How to Choose a General Contractor: Complete Guide (2026)

How to Choose a General Contractor Without Getting Burned

Hiring a general contractor is one of the biggest financial decisions most homeowners make outside of buying the house itself. A kitchen remodel in Mercer County runs $40,000-$80,000. A whole-home renovation can easily exceed $150,000. Hand that money to the wrong person and you are looking at unfinished work, code violations, legal battles, and a home that is worth less than when you started.

We are writing this as contractors. The5thwall is a licensed, insured general contractor based in Lawrence, NJ. We work across Princeton, Hamilton, Ewing, Hopewell, West Windsor, Pennington, Robbinsville, Plainsboro, and the surrounding Mercer County area. We are going to tell you exactly how to evaluate us and every other contractor you talk to. If that means you hire someone else because they checked every box and we did not, good. An informed homeowner makes better decisions, and that is better for the entire industry.

This guide covers everything: what to look for, what to ask, what should make you walk away, and how the process works in New Jersey specifically.

Why Choosing the Right Contractor Matters

The stakes are not abstract. They are financial, legal, and emotional.

Financial reality: The average NJ homeowner spends $50,000-$120,000 on a major renovation. That is not a number you can absorb twice if the first contractor fails.

The horror stories are real. Every contractor in Central NJ has been called to fix someone else's disaster. Walls framed out of plumb. Electrical work done without permits that fails inspection when the homeowner tries to sell. Bathrooms that leak into the floor below within six months because the waterproofing was skipped. Contractors who took $30,000 deposits and never came back.

Legal exposure: In New Jersey, if you hire an unregistered contractor and a worker gets injured on your property, you can be held personally liable. If unpermitted work is discovered during a home sale, you as the homeowner are responsible for bringing it up to code — even if the contractor told you permits were not needed.

The good news: These problems are almost entirely preventable. Homeowners who do their homework before signing a contract almost never end up in these situations. This guide gives you the homework.

10 Things to Look for in a General Contractor

1. NJ Home Improvement Contractor (HIC) Registration

This is non-negotiable. New Jersey requires every contractor performing home improvement work over $500 to register with the NJ Division of Consumer Affairs. The registration number (starts with 13VH) must appear on every contract, estimate, advertisement, and business card.

What registration means: the contractor has submitted proof of identity, a business address, and is subject to the NJ Consumer Fraud Act and the Contractors' Registration Act. They can be investigated and penalized for violations.

What registration does NOT mean: it is not a skills test. NJ does not test contractors on building knowledge or inspect their work as part of registration. It is an administrative requirement to legally operate — not a quality guarantee. That is why the other nine items on this list matter just as much.

For a deep dive on what NJ licensing actually means (and does not mean), read our licensed contractor guide.

2. Insurance — Both General Liability and Workers Compensation

Ask for a Certificate of Insurance (COI) before any work begins. Do not accept "yeah, we are insured" as an answer. A COI is a document issued by the insurance company that lists coverage types, limits, and expiration dates.

General liability insurance covers damage the contractor causes to your property. A plumber floods your basement, a framing crew damages your existing hardwood floors, a ladder goes through a window — general liability pays for it. Require a minimum of $1 million per occurrence.

Workers compensation insurance covers injuries to the contractor's employees on your property. This is the one most homeowners overlook. If an uninsured worker falls off a ladder at your house, your homeowners insurance may be on the hook for their medical bills. In New Jersey, any contractor with employees is legally required to carry workers comp.

You can call the insurance carrier listed on the COI to verify the policy is active. Fake certificates exist. A two-minute phone call eliminates that risk.

3. Verifiable References

Any contractor who cannot provide references from recent projects in your area should not be on your list. Ask for at least three references from the last 12 months, and actually call them.

When you call, ask specific questions:

• Did the project come in on budget? If not, why?
• Did the project finish on time? If not, how was it handled?
• How was communication throughout the project?
• Were there any surprises or issues? How were they resolved?
• Would you hire them again?

Online reviews matter too, but they are not a substitute for direct conversations with past clients. A contractor with 200 five-star Google reviews and zero willingness to connect you with a past client is a red flag.

4. A Portfolio of Completed Work

Photos and descriptions of past projects tell you what a contractor is capable of and what kind of work they typically do. A contractor who primarily does commercial build-outs may not be the right fit for your kitchen remodel. A contractor who specializes in new construction may not have the patience or skill for renovation work, which requires solving problems in existing structures.

Look for projects similar to yours in scope, style, and budget. Even better, ask if you can visit a completed project or a current job site.

5. Communication Style That Works for You

Pay attention to how a contractor communicates during the estimate process. That is exactly how they will communicate during the project.

• Do they return calls and emails within a reasonable timeframe?
• Do they listen to what you want, or do they immediately start telling you what you should want?
• Do they explain things in plain language or hide behind jargon?
• Do they show up on time for the estimate?

If communication is poor before they have your money, it will be worse after. This is one of the most common complaints homeowners have about contractors, and it is completely avoidable if you pay attention during the hiring process.

6. Detailed Written Estimates

A legitimate estimate is not a number on a napkin. It should be a document that breaks down:

• Materials: What products are being used, what brand, what grade
• Labor: How many crew members, how many days
• Scope: Exactly what work is included and what is excluded
• Allowances: If exact selections have not been made (tile, fixtures, countertops), what dollar amount is budgeted
• Permits: Whether permit costs are included
• Contingency: Whether the estimate includes a contingency for unknowns (it should for renovation work)

If two estimates look wildly different in price, it usually means they are not covering the same scope. A $30,000 bathroom remodel estimate that does not include tile, fixtures, or plumbing relocation is not cheaper than a $45,000 estimate that includes everything. It is just less honest.

7. Realistic Timelines

Be skeptical of any contractor who promises your project will be done faster than everyone else. Renovation work takes time, especially in New Jersey where permit approvals, inspections, and material lead times add weeks to every project.

A good contractor will give you a realistic timeline that accounts for:

• Permit processing (2-6 weeks in most Mercer County townships)
• Material lead times (custom cabinets can take 6-10 weeks)
• Inspection scheduling
• Weather impacts for exterior work
• Subcontractor availability

If a contractor tells you they can gut and rebuild your kitchen in three weeks, they are either cutting corners or lying. For realistic expectations on project timelines in NJ, see our renovation timeline guide.

8. Clean Jobsite Practices

How a contractor maintains a job site tells you everything about how they run their business. A clean, organized site means they respect your home, their tools, and the work.

Ask about their daily cleanup process. Ask past references about jobsite cleanliness. If you visit a current job site, look for:

• Materials stored neatly and protected from weather
• Dust barriers between the work area and living space
• Debris removed regularly, not piled up for weeks
• Tools organized, not scattered everywhere
• Protection on floors and surfaces outside the work area

Homeowners in Lawrence, Princeton, and West Windsor often continue living in their homes during renovations. A contractor who does not respect that reality will make your life miserable for months.

9. Warranty and Guarantee

Every contractor should stand behind their work with a written warranty. Ask specifically:

• What does the warranty cover?
• How long does it last? (One year is standard minimum for workmanship; two or more years is better)
• Does it cover materials, labor, or both?
• What is the process for making a warranty claim?
• Is the warranty transferable if you sell the home?

A contractor who will not put their warranty in writing does not actually have a warranty. Verbal promises are worthless when a tile starts cracking 14 months after installation.

10. Reasonable Payment Terms

How a contractor structures payments tells you a lot about their financial stability and business practices.

Standard payment structure for NJ renovations: - 10-15% deposit upon contract signing - Progress payments tied to completed milestones - Final payment (10-15%) upon completion and your satisfaction

We will cover payment red flags in detail later in this guide, but the short version: never pay more than 15% upfront, never pay for work that has not been completed, and never pay the final amount until you are satisfied with a final walkthrough.

15 Questions to Ask Before Hiring a General Contractor

These are not theoretical. Ask every single one of these to every contractor you are considering. Their answers — and how they answer — will tell you who is legitimate and who is not.

Licensing and Legal

1. What is your NJ HIC registration number? If they hesitate, that is your answer. The number should start with 13VH and they should know it by heart.

1. How long have you been in business under this name? Contractors who change business names frequently may be running from bad reviews or legal issues. Search the NJ Division of Consumer Affairs for their history.

1. Do you pull permits for your projects? The only acceptable answer is yes. Any contractor who suggests skipping permits to "save you money" is putting your investment at risk. Read our NJ renovation permits guide for what requires a permit.

1. Will you provide a written contract before work begins? Again, the only acceptable answer is yes. New Jersey law requires a written contract for home improvement work over $500.

Insurance and Protection

1. Can you provide a current Certificate of Insurance? They should be able to email this within a day. If it takes longer, the policy may be expired or nonexistent.

1. Does your insurance include workers compensation? If they have employees (and most GCs do), the answer must be yes. If they claim to be a sole proprietor with no employees, verify that they are not showing up with a crew of "subcontractors" who are actually uninsured workers.

1. What is your general liability coverage limit? Minimum $1 million per occurrence. Do not accept less for any renovation project.

Project Specifics

1. Have you done projects similar to mine in scope and budget? A contractor who primarily does $15,000 bathroom refreshes may struggle with a $200,000 whole-home renovation. Make sure their experience matches your project.

1. Who will be on site daily managing the project? On larger projects, the owner may not be there every day. Know who your day-to-day contact will be and meet them before signing.

1. What subcontractors do you use, and are they also licensed and insured? General contractors use subcontractors for electrical, plumbing, HVAC, and other specialty work. Those subs should be licensed in their trade and insured. Your GC is responsible for verifying this.

1. How do you handle change orders? Changes happen on every project. A professional contractor has a written change order process: you agree to the added scope and cost in writing before the work is done. No surprises on the final invoice.

1. What is your realistic timeline for this project? Compare this answer across multiple contractors. If one says four weeks and everyone else says eight to ten, the outlier is either cutting corners or buying your business with an unrealistic promise.

Communication and Process

1. How will you communicate project updates? Weekly updates? Daily photos? A project management app? Know what to expect so you are not chasing your contractor for information.

1. What happens if we disagree about something during the project? This question catches people off guard. A professional will describe a resolution process. Someone who gets defensive or dismissive is showing you how they handle conflict.

1. Can you provide three references from projects completed in the last year? And then actually call them. This is the step most homeowners skip, and it is the most valuable one.

Bonus Questions for NJ Specifically

1. Are you familiar with building codes in my township? Code requirements vary across Lawrence, Princeton, Hamilton, Ewing, and other Mercer County towns. A contractor who works locally will know these nuances.

1. How do you handle NJ inspection scheduling? Inspections are required at multiple stages of permitted work. A contractor who manages this process smoothly keeps your project on track.

Red Flags That Should Make You Walk Away

Not every red flag means a contractor is a scam. Some just mean they run a sloppy business, which is nearly as dangerous when they are working on your home. Here are the ones that should end the conversation.

No License Number

If a contractor cannot or will not provide their NJ HIC registration number, the conversation is over. Operating without registration is illegal in New Jersey. If they are willing to break that law, what other corners are they cutting?

Demands a Large Upfront Payment

Any contractor asking for more than 10-15% upfront before work begins is either undercapitalized (meaning they need your money to buy materials for someone else's job) or running a deposit scam. New Jersey's Home Improvement Practices regulations set guidelines on deposits. A contractor who needs $20,000 before picking up a hammer does not have a stable business.

No Written Contract

New Jersey law requires a written contract for home improvement work exceeding $500. The contract must include the contractor's HIC registration number, a description of the work, the total price, payment schedule, and start/completion dates. A contractor who wants to work on a handshake is not just unprofessional — they are breaking the law.

Will Not Pull Permits

Permits exist to protect you. They ensure work meets building codes and gets inspected by the township. When a contractor says "we do not need a permit for this" or "we can save you money by skipping the permit," they are creating a liability that you will own forever. Unpermitted work can derail a home sale, void your homeowners insurance, and create safety hazards. Check our guide on NJ renovation permits to know what requires a permit.

No Insurance Certificate

"We are insured" is not proof. If they cannot produce a Certificate of Insurance, assume they are not insured. The risk to you is too high to take their word for it.

Pressures You to Decide Now

"This price is only good today." "I have another job starting Monday, so I need your answer by Friday." "If you don't sign now, I can't guarantee the schedule." These are sales tactics, not construction realities. A legitimate contractor will give you time to make an informed decision because they want informed clients who will not become problems later.

Cannot Provide References

Any established contractor has happy clients who are willing to vouch for them. If they cannot connect you with a single past client, either they do not have happy clients or they have not been in business long enough to have a track record. Neither is acceptable for a major renovation.

Only Accepts Cash

Cash-only businesses exist to avoid taxes, and they leave you without a paper trail. If something goes wrong, you have no proof of payment. If they disappear, you have no recourse. Always pay by check or credit card so there is a documented record of every transaction.

Dramatically Lower Bid Than Everyone Else

If you get four bids and three are in the $60,000-$70,000 range while one is $38,000, that $38,000 bid is not a bargain. It means they are using cheaper materials, cutting scope, skipping steps, using uninsured labor, or planning to hit you with change orders once the project starts. The cheapest bid almost always costs more in the end.

No Physical Business Address

A contractor operating out of a P.O. box or with no verifiable business address is hard to find when something goes wrong. Legitimate contractors have a shop, office, or at minimum a well-established local presence you can verify.

How to Check Contractor Licenses in New Jersey

New Jersey uses the term "registration" rather than "license" for general contractors. Here is exactly how to verify a contractor's status.

Step-by-Step Verification Process

1. Go to the NJ Division of Consumer Affairs website at njconsumeraffairs.gov
2. Navigate to the license verification section and select "Home Improvement Contractor" from the list
3. Search by contractor name or registration number (the number starts with 13VH)
4. Review the results for registration status, effective dates, and any enforcement actions

What to Look for in the Results

• Active status: The registration must be current, not expired or suspended
• Matching information: The business name should match what is on the estimate and contract
• No enforcement actions: Check for complaints, fines, or disciplinary actions
• Registration number format: Always starts with 13VH followed by numbers

What the HIC Registration Number Means

The 13VH prefix identifies the contractor as registered under the Home Improvement Contractor category with the NJ Division of Consumer Affairs. This number must legally appear on all contracts, written estimates, advertisements, business cards, and commercial vehicles.

The5thwall LLC is registered as NJ HIC #13VH04175700. You can verify this at any time through the Division of Consumer Affairs website.

Beyond State Registration

Some municipalities in Mercer County require additional local contractor registration or licensing. Check with your township's building department — Lawrence, Princeton, Hamilton, and Ewing each have their own requirements that supplement state registration.

Insurance Requirements Explained

Understanding contractor insurance protects you from financial exposure that most homeowners do not realize exists until it is too late.

General Liability Insurance

What it covers: Physical damage to your property caused by the contractor's work, plus injuries to third parties (like a visitor who trips over construction materials).

Minimum coverage: $1 million per occurrence, $2 million aggregate. For projects over $100,000, consider requiring higher limits.

Real scenario: A contractor's crew is installing recessed lighting and accidentally punctures a water pipe in the ceiling. Water floods the floor below, destroying hardwood floors, drywall, and furniture. Without general liability insurance, the contractor might say "sorry" and disappear. With insurance, the damage is covered by their policy.

Workers Compensation Insurance

What it covers: Medical expenses and lost wages for workers injured on the job.

NJ legal requirement: Every employer in New Jersey must carry workers compensation insurance. Sole proprietors with no employees may be exempt, but any contractor with a crew must have it.

Real scenario: A worker falls from scaffolding at your house and breaks his back. Without workers comp, that worker (or their attorney) may file a claim against your homeowners insurance. Your premiums could skyrocket, or worse, you could face a personal liability lawsuit.

How to verify: The worker's comp policy should be listed on the Certificate of Insurance. You can also verify NJ workers compensation coverage through the NJ Department of Banking and Insurance.

What Happens If They Are Uninsured

If an uninsured contractor damages your property, your homeowners insurance may cover it — but your deductible applies, your premiums will likely increase, and your insurer may deny the claim if they determine you hired an uninsured contractor knowingly.

If an uninsured worker is injured on your property, you could face medical bills, legal fees, and a lawsuit that your homeowners policy may not fully cover.

The bottom line: verifying insurance takes 15 minutes. Dealing with an uninsured incident can take years and cost tens of thousands of dollars.

Getting and Comparing Multiple Bids

How Many Bids to Get

Three is the minimum. Four or five is better for large projects. Fewer than three does not give you enough data points. More than five becomes unmanageable and wastes contractors' time — most legitimate contractors invest 3-5 hours in preparing a detailed estimate.

How to Compare Bids Accurately

The biggest mistake homeowners make is comparing total numbers without comparing scope. A $50,000 bid and a $65,000 bid might include completely different work.

Create a comparison matrix:

When bids vary significantly, ask each contractor to explain their pricing. Often the differences come down to material quality, scope assumptions, or how much detail they put into the estimate.

Why the Cheapest Bid Is Rarely the Best

We see this constantly across Lawrence, Princeton, Hamilton, and the rest of Mercer County. A homeowner picks the lowest bid, and six months later they are calling us to fix the result.

The cheapest bid often means:

• Lower quality materials that will need replacement sooner
• Excluded scope that gets added back as change orders
• Uninsured or unlicensed subcontractors who create liability
• No contingency for the unexpected issues that renovation work always uncovers
• Unrealistic timeline that leads to rushed, sloppy work

The best value is rarely the lowest number. It is the contractor who gives you a thorough, honest estimate, does quality work, stands behind it with a warranty, and finishes on time. That contractor is almost never the cheapest. They are usually in the middle of the pack or slightly above. Learn more about how renovation costs work in NJ in our home renovation ROI guide.

Contract Essentials: What Should Be in Writing

A proper construction contract protects both you and the contractor. In New Jersey, a written contract is legally required for home improvement work over $500. Here is what it must include.

Scope of Work

The most important section. It should describe in detail exactly what work will be performed. Not "remodel kitchen" but specific items:

• Remove existing cabinets, countertops, flooring, and backsplash
• Install new cabinets (brand, style, number of units)
• Install new countertops (material, square footage, edge profile)
• Install new flooring (material, square footage)
• Relocate sink plumbing from X to Y
• Install new electrical circuits for island (number, amperage)
• Paint walls and ceiling (number of coats, paint brand)

The more specific the scope, the fewer disputes later. If something is not in the contract, it is not included — regardless of what was discussed verbally.

Project Timeline

The contract should include:

• Start date (or conditions that trigger the start, like permit approval)
• Estimated completion date
• Milestone dates for major phases
• Language about delays: What happens if the project falls behind? What constitutes an excusable delay (weather, material backorders, permit delays) versus an inexcusable one?

Payment Schedule

Tied to milestones, not calendar dates. Example for a kitchen remodel:

• 10% upon contract signing
• 20% upon completion of demolition and rough framing
• 20% upon completion of mechanical rough-ins (plumbing, electrical, HVAC)
• 20% upon completion of drywall and cabinet installation
• 20% upon completion of countertops, flooring, and fixtures
• 10% upon final walkthrough and punch list completion

Never agree to a payment schedule that front-loads money before work is done.

Change Order Process

Changes will happen. The contract should specify:

• All changes must be documented in writing before work begins
• Each change order must include the revised scope, added cost (or credit), and impact on timeline
• Both parties must sign the change order before the changed work proceeds

Without a formal change order process, you end up arguing about what was agreed to, what was included, and who owes what.

Warranty

The contract should spell out the warranty terms: what is covered, for how long, and how to make a claim. New Jersey does not mandate a specific warranty period for home improvements, but industry standard is one to two years for workmanship.

Dispute Resolution

How will disagreements be resolved? Options include:

• Mediation: A neutral third party helps you reach agreement. Less expensive than litigation.
• Arbitration: A neutral third party makes a binding decision. Faster than court.
• Litigation: Court. Expensive and slow, but sometimes necessary.

The contract should specify which method applies. Many NJ contractors include a mediation-first clause, which is generally favorable to homeowners because it is faster and cheaper than going straight to court.

NJ-Specific Contract Requirements

Under NJ law, home improvement contracts must also include:

• The contractor's NJ HIC registration number
• The contractor's legal name, business address, and phone number
• A notice of the homeowner's right to cancel within three business days (for contracts signed at your home)
• A description of any guarantee or warranty

Payment Schedule Red Flags

Payment disputes are one of the top complaints filed against NJ contractors with the Division of Consumer Affairs. Protect yourself by understanding what is normal and what is not.

The 10-15% Rule for Deposits

A deposit of 10-15% of the total contract price is standard and reasonable. It demonstrates your commitment and allows the contractor to order materials and reserve their schedule. Some homeowners in Hamilton, Ewing, and Robbinsville have told us about contractors demanding 30%, 40%, even 50% upfront. That is not a deposit. That is a loan to an undercapitalized business.

Milestone-Based Payments Are Standard

Every payment after the deposit should correspond to completed work:

• Rough framing complete and inspected
• Mechanical rough-ins complete and inspected
• Drywall complete
• Finishes installed
• Final walkthrough approved

You pay for what you can see and verify. Period.

Never Pay in Full Before Completion

This should be obvious, but it happens. A contractor says the project is "basically done" except for a few small items, and asks for the final payment. Those small items never get finished. Always hold 10-15% of the total until you are completely satisfied and all punch list items are resolved.

What to Do If a Contractor Asks for More Money Mid-Project

If a contractor claims they need additional money beyond the agreed schedule, ask why:

• Legitimate reason: Unexpected conditions were discovered (hidden water damage, outdated wiring that does not meet code). This should be documented as a change order with your written approval.
• Illegitimate reason: They underestimated the job, spent your deposit on another project, or are trying to squeeze more money out of you. Refer to the contract terms.

If they threaten to stop work unless you pay outside the agreed schedule, that is a breach of contract on their part. Document everything and consult an attorney if necessary.

How to Check NJ Contractor References the Right Way

Getting references is step one. Knowing how to use them is step two.

Go Beyond the Names They Give You

The references a contractor provides are obviously their happiest clients. That is fine — you still want to talk to them. But also:

• Check Google, Yelp, and Facebook reviews for patterns. One bad review is normal. A pattern of similar complaints (communication, timeline, quality) is a warning.
• Search the NJ Division of Consumer Affairs for complaints and enforcement actions.
• Search your local township for permits pulled in the contractor's name. If they claim to do a lot of work in Princeton or Lawrence but have no permit history there, ask why.
• Check the Better Business Bureau for complaints and resolution history.

What to Ask References

Go beyond "were you happy with the work?" Ask questions that reveal how the contractor handles problems — because every project has them.

• What surprised you about the project (good or bad)?
• How did the contractor handle a mistake or unexpected issue?
• Was the final cost within the original estimate? If it went up, by how much and why?
• How long after "completion" did it take to finish punch list items?
• Did you feel informed throughout the project, or did you have to chase updates?

The answers to these questions tell you more than a star rating ever will.

Working With Your Contractor During the Project

Hiring the right contractor is step one. Managing the relationship during the project matters just as much.

Establish Communication Expectations Upfront

Before work begins, agree on:

• How often you will get updates (daily, twice a week, weekly)
• Who your primary contact is (the owner, a project manager, a site foreman)
• How updates will be delivered (phone call, text, email, project app)
• How quickly you need to respond to questions (decisions on materials, design changes, etc. — your delays become the project's delays)

Document Everything

Keep a project file with:

• The signed contract and all change orders
• Every invoice and proof of payment
• Photos of progress at each stage
• Notes from conversations (date, who you spoke with, what was discussed)
• Permit documents and inspection results
• The Certificate of Insurance

This documentation protects you during the project and is valuable if you sell the home later.

Visit the Job Site Regularly

Even if you are not living there during the renovation, visit regularly. You do not need to micromanage — in fact, please do not — but regular visits let you catch issues early, ask questions while the walls are still open, and maintain a presence that keeps the crew accountable.

Handle Problems Early

If something looks wrong, say something immediately. Do not wait until the project is done to bring up concerns. A problem caught during framing is a $200 fix. The same problem caught after drywall is a $2,000 fix. The same problem caught after tile is a $5,000 fix.

Frame your concerns constructively. "I noticed the outlet placement in the kitchen seems different from what we discussed — can we look at the plan together?" works better than "You did this wrong."

Be Decisive on Selections

One of the biggest causes of renovation delays is homeowner indecision on materials. When your contractor needs you to pick a tile, pick a tile. Every week you delay a decision is a week added to the timeline. If you need help making design decisions, start with our home remodel checklist to get organized before the project begins.

Pay on Schedule

Just as you expect the contractor to perform on schedule, they expect to be paid on schedule. When a milestone is completed and verified, process the payment promptly. Withholding payment on completed work is as damaging to the relationship as a contractor demanding payment for incomplete work.

Prepare for the Unexpected

Renovation projects, especially in older homes throughout Princeton, Hopewell, Pennington, and the rest of Mercer County, uncover surprises. Water damage behind walls. Outdated plumbing that does not meet code. Asbestos in old flooring. A good contractor will bring these to you immediately with options and costs. Budget 10-15% above your expected cost for contingencies. For common issues homeowners face, read our guide on home renovation mistakes to avoid.

The Punch List Process

At the end of the project, do a thorough walkthrough with your contractor and create a punch list — a written list of items that need to be completed, corrected, or touched up. This is normal. Every project has a punch list.

Be thorough but reasonable. A scratch on a cabinet door is a legitimate punch list item. A demand to redo all the tile because one grout line is 1/16" off is not.

Agree on a timeline to complete the punch list (typically one to two weeks) and withhold final payment until everything is resolved to your satisfaction.

New Jersey-Specific Protections for Homeowners

New Jersey provides several legal protections that homeowners should know about.

The Three-Day Right to Cancel

Under NJ law and federal FTC rules, if you sign a home improvement contract at your home (not at the contractor's office), you have three business days to cancel without penalty. The contractor must provide you with a written notice of this right. If they do not, the cancellation period extends indefinitely.

NJ Consumer Fraud Act

The NJ Consumer Fraud Act provides treble (triple) damages for unconscionable business practices. If a contractor engages in fraud, deception, or misrepresentation, you can recover three times your actual damages plus attorney's fees. This is one of the strongest consumer protection statutes in the country.

NJ Contractors' Registration Act

Unregistered contractors face fines up to $10,000 per offense. Homeowners who hire unregistered contractors may lose certain legal protections. Always verify registration before signing a contract.

Filing a Complaint

If you have a dispute with a registered NJ contractor, you can file a complaint with the NJ Division of Consumer Affairs. They investigate complaints and can take action including fines, suspension, or revocation of registration. You can also file in NJ Small Claims Court for disputes up to $3,000, or in NJ Superior Court for larger amounts.
