Kitchen, Bath, Basement & Renovation — For Lawrenceville's Character Homes and Village Properties

Lawrenceville Village — Character Homes That Deserve Careful Work#

Lawrenceville is the historic village center within Lawrence Township, anchored by Main Street's tree-lined shops and the prestigious Lawrenceville School. Properties here often date from the early-to-mid 20th century, carrying distinctive architectural details — arched doorways, built-in cabinetry, original hardwood floors, plaster walls — that deserve contractors who will preserve rather than demolish.

The 5th Wall is based right here in the Lawrence/Lawrenceville area. Many of our past projects have been in these exact neighborhoods, and we understand the construction era of most homes: knob-and-tube wiring, galvanized plumbing, original millwork, and 70-100 year old framing that doesn't match modern stud dimensions.

Lawrenceville Housing Stock#

Historic Main Street Area — Craftsman & Colonial-Revival Homes#

The area radiating from Lawrenceville School and Main Street features older character homes — Craftsman bungalows with built-in cabinetry, Colonial-revival homes with formal dining rooms, and Cape Cods from the 1940s. These homes need kitchen modernization (most original kitchens are 6x8 feet), bathroom additions (often only one full bath), and energy upgrades.

Princeton Pike & Federal City Road — Mid-Century Suburbia#

The neighborhoods along Princeton Pike and Federal City Road contain colonial and bi-level homes from the 1970s-1980s. These are now 40-50 years old — the renovation sweet spot. Original kitchens, bathrooms, roofing, and siding are all due for replacement.

Franklin Corner & Cold Soil Area — Larger-Lot Homes#

The residential streets between Franklin Corner Road and Cold Soil Road feature well-maintained homes on generous lots. Renovation projects here often include whole-home updates, basement finishing, and outdoor living additions.

What We Build in Lawrenceville#

Kitchen Remodeling — Typical Budget: $30,000-$70,000#

Lawrenceville kitchens often require a balance — modernizing functionality while preserving the historic character that makes the village special. Our approach: refinish original hardwood floors when possible, install period-appropriate cabinetry styles, use classic subway tile or stone backsplashes, and select modern appliances that don't visually dominate the space.

Bathroom Remodeling — Typical Budget: $15,000-$35,000#

Bathroom additions are common in Lawrenceville because many pre-war homes were built with only one full bath. We carve out space from oversized closets, hallway alcoves, or unfinished attic areas to add second or third bathrooms while respecting the home's original flow.

Basement Finishing — Typical Budget: $30,000-$65,000#

Pre-war basements in Lawrenceville often have lower ceilings (7 feet is common) and stone or rubble foundations. We assess each basement before committing — some are ideal for finishing, others need excavation or waterproofing first.

Whole-Home Renovations#

Many Lawrenceville homes benefit from whole-home updates that modernize plumbing, electrical, HVAC, and finishes in a single coordinated project. We manage these end-to-end.

Questions answered

Frequently asked

Yes — that is exactly what we specialize in. We assess original features (millwork, hardware, flooring, plaster details), create a preservation plan, and selectively modernize systems behind the walls while maintaining the home's essential character.

Kitchen remodels in Lawrenceville typically range from $30,000 for a budget refresh to $70,000 for a premium renovation. Historic homes may cost more due to the care required when working with older framing, plaster walls, and preserving original details.

Yes. Adding a second or third bathroom is one of the most common Lawrenceville projects because many pre-war homes were built with only one full bath. We identify the best location (often an oversized closet, hallway alcove, or unfinished attic space), handle plumbing routing, and add the bathroom without disrupting the home's original flow.

Yes. Many Lawrenceville homes have plaster walls, and we have the experience to repair cracks, patch damaged areas, and finish new drywall to match existing plaster textures. When plaster is beyond repair, we replace it with drywall matched to the original profile.

Yes. The 5th Wall holds NJ Home Improvement Contractor license and carries $2M general liability insurance. Lawrence Township (which includes Lawrenceville village) is literally our home base — we are fully licensed, insured, and experienced in this specific market.

Yes. Many Lawrenceville kitchens are 6x8 feet or smaller, and we specialize in making compact kitchens functional and beautiful. Full-custom cabinetry designed to maximize every inch, proper lighting design, and clever storage solutions make a big difference in small pre-war kitchens.

Whole-home renovations in Lawrenceville's character homes typically take 4-7 months depending on scope, age of the home, and how much of the original structure is preserved. We provide a detailed project timeline before work begins.

Depends on scope. Single-room renovations (one kitchen, one bathroom) usually allow you to stay. Whole-home renovations or projects involving major plumbing/electrical/HVAC typically require temporary relocation for 2-4 weeks. We'll give you an honest assessment upfront.
