Renovating in New Jersey's Capital#

Trenton carries a housing stock unlike any other city in Mercer County. Victorian row homes in Mill Hill. Early-American colonials in Hiltonia. Pre-war two-families in Chambersburg. Mid-rise multifamily buildings along West State Street. Whether you're restoring a historic brownstone or modernizing a residential investment property, Trenton renovations demand expertise beyond standard suburban remodeling.

The 5th Wall is based in Lawrence — just eight minutes from downtown Trenton — and Trenton has been part of our core service area since we opened. We understand the unique challenges that come with pre-war construction: plaster walls, knob-and-tube wiring, galvanized plumbing, cast-iron drain stacks, and century-old framing that doesn't match modern dimensions. We also understand NJ's lead-safe work practices, asbestos awareness requirements, and the historic-district review process that some Trenton neighborhoods require.

Trenton Neighborhoods We Serve#

Mill Hill & Hanover Academy — Historic District Work#

Mill Hill is Trenton's most prominent historic district, featuring Victorian row homes, Italianate townhouses, and Federal-era masonry structures dating from the 1840s through the early 1900s. Homes here often need behind-the-scenes modernization — updated electrical panels, PEX plumbing replacing galvanized, new HVAC systems — while preserving original architectural details. Exterior changes within the historic district require design review, which we navigate routinely.

Chambersburg & Villa Park — Working-Class Row Homes#

The Chambersburg neighborhood is one of Trenton's most densely built areas, with row homes and two-family houses on narrow lots. Renovation projects here typically focus on kitchen modernization, single-bathroom expansions (many Chambersburg homes were built with one bathroom), and basement finishing. Tight party walls mean sound isolation matters.

Hiltonia & Berkeley Square — Single-Family Colonials#

Hiltonia and Berkeley Square feature single-family colonials and Tudors on larger lots, many dating from the 1920s through the 1940s. These are strong renovation candidates — solid construction, good bones, but 80-100 year old kitchens, bathrooms, and mechanical systems that are well past replacement age.

Ewing-Trenton Border & West State Street — Multi-Family Investment#

Many Trenton renovation projects involve investor-owned two-families and small multi-family buildings. We handle these with the same quality we bring to owner-occupied work — new kitchens that attract quality tenants, bathrooms that meet code, and electrical/plumbing upgrades that pass rental inspections.

What We Build in Trenton#

Kitchen Remodeling — Typical Budget: $22,000-$55,000#

Most Trenton kitchens are compact (8x10 feet is common in pre-war homes). Our most-requested kitchen project here is a thoughtful gut-renovation that modernizes the space without losing the historic character — refinished original hardwood floors, period-appropriate cabinetry, subway tile, and modern appliances sized for older layouts.

Bathroom Remodeling — Typical Budget: $12,000-$28,000#

Trenton bathrooms often need full gut-renovations. Proper waterproofing is critical because most pre-war bathrooms were built before modern moisture standards. We install Schluter systems on every tile installation.

Basement Finishing — Typical Budget: $25,000-$55,000#

Trenton basements present unique challenges — older foundations, potential moisture issues, low ceiling heights. We assess each basement before committing to finishing and include egress window installation when required by code.

Roofing & Siding#

Most Trenton homes are 80-130 years old with roofs that have been replaced multiple times. We handle full tear-offs, flat-roof systems for the flat-top row homes in Chambersburg, and vinyl or fiber-cement siding replacement.

Whole-Home Renovations#

Trenton's revitalization wave has created real demand for full-scope renovation of historic homes. We manage these projects end-to-end — demolition, structural, rough-ins, finishes, cleanup.

Questions answered

Frequently asked

Yes. The 5th Wall has extensive experience with Trenton's pre-war housing stock — Mill Hill Victorians, Hiltonia colonials, Chambersburg two-families. We handle the specific challenges of older construction (plaster walls, knob-and-tube wiring, galvanized plumbing) while respecting original architectural details.

Kitchen remodels in Trenton typically range from $22,000 for a functional refresh to $55,000 for a premium gut-renovation. The most common Trenton kitchen remodel costs $30,000-$40,000 and includes new cabinetry, quartz countertops, tile backsplash, and appliances. Historic homes may cost more due to the care required when working with older framing and plaster walls.

Yes. Our crew is EPA Lead-Safe certified, which is required for renovation work on homes built before 1978. The vast majority of Trenton's housing stock falls in that category. We follow proper containment, cleanup, and disposal protocols on every project.

If your property is within Mill Hill, Hanover Academy, or another designated historic district, exterior changes — including facades, windows, roofing materials, and visible additions — require Historic Preservation Commission review. Interior renovations generally do not. We handle the HPC submission process when required.

Yes, but Trenton basements require careful assessment first. Older foundations, potential moisture issues, and low ceiling heights are common considerations. We evaluate each basement, recommend waterproofing if needed, and build egress windows when code-required.

Yes. Many of our Trenton projects are investor-owned two-family and small multi-family buildings. We bring the same quality to rental properties as owner-occupied work — focused on kitchens, bathrooms, and mechanical upgrades that attract quality tenants and pass rental inspections.

Yes. The 5th Wall holds NJ Home Improvement Contractor license and carries $2M general liability insurance. We are fully licensed and insured for all residential renovation work in Trenton and throughout New Jersey.

Initial walkthroughs are typically scheduled within one business day. Actual project start depends on permit processing (Trenton Building Department timelines vary by scope) and our current schedule — usually 3-8 weeks from signed contract to demolition.
