Kitchen, Bath & Whole-Home Renovation — For Pennington's Character Homes and Historic Farmhouses

Pennington — Village Character, Modern Expectations#

Pennington is a small borough with big charm, sitting just north of Ewing and east of Hopewell. Its compact downtown, tree-lined streets, and mix of historic and newer homes give it a village feel that residents fiercely protect. Properties range from pre-Civil War farmhouses on the outskirts to 1990s colonial developments within walking distance of Main Street shops and restaurants.

The 5th Wall appreciates the craftsmanship that Pennington homes deserve. We're based 15 minutes south in Lawrence and have completed projects across the borough and surrounding Hopewell Township.

Downtown Pennington & Main Street — 19th Century Character Homes#

The walkable downtown area features Victorian homes, Federal-era buildings, and Craftsman bungalows dating from the 1850s-1920s. Many of these homes are in the borough's historic district, which adds design-review considerations for exterior changes.

Pennington Rocky Hill Road Area — Country Estates#

The rural edges of Pennington feature farmhouses from the 18th and 19th centuries on larger lots, alongside newer custom builds designed to fit the rural character.

1990s-2000s Developments — Newer Colonials#

Several planned developments along Federal City Road and Lewisville Road contain colonial and Cape Cod homes from the 1990s-2000s. These are structurally solid but often have builder-grade finishes that homeowners are now upgrading.

What We Build in Pennington#

Kitchen Remodeling — Typical Budget: $32,000-$80,000#

Pennington kitchen renovations often involve historic-appropriate design in older homes and mid-to-high-range updates in newer developments. We carefully select cabinetry, countertop, and fixture styles that complement each home's architectural era.

Bathroom Remodeling — Typical Budget: $15,000-$40,000#

Pennington bathroom projects range from historic second-bathroom additions (carved from existing space in pre-war homes) to premium master bath renovations in newer developments.

Whole-Home Renovations#

Full-scope renovations of historic Pennington farmhouses are some of our most rewarding projects. These require a balance of modernizing systems (HVAC, electrical, plumbing, insulation, windows) while preserving original architectural features.

Basement Waterproofing & Finishing#

Pennington's higher water table in some areas requires proper waterproofing before basement finishing. We assess each basement and recommend either waterproofing + finishing or leaving the basement as storage.

Roofing & Siding#

Many Pennington homes need roof replacements on original structures and sensitive exterior work that matches the borough's historic character.

Yes. For historic homes, we carefully source matching siding, trim, window profiles, and roofing materials to maintain architectural consistency. For additions, we design to complement the original architecture rather than contrast with it.
