Overview

Home Additions in Trenton — for homeowners in Mercer County, built by a team that lives here.

As New Jersey's state capital, Trenton carries a rich architectural heritage — Victorian row homes in the Mill Hill district, early American colonials in the Hiltonia neighborhood, and a growing number of mixed-use renovation projects throughout the city. Trenton is also in the middle of a revitalization wave, with homeowners and investors renovating properties to meet rising demand for quality housing in the urban core.

Trenton renovation projects often involve older buildings with unique challenges: plaster walls, outdated wiring, lead paint, and century-old plumbing. These require a contractor who understands pre-war construction techniques and NJ remediation requirements. Whether you are restoring a historic row home or modernizing a multi-family investment property, Trenton projects demand expertise beyond standard suburban remodeling.

Scope of work

Every additions project covers the full scope — start to finish.

One contractor pulls every trade under one roof — design, demolition, rough-in, finish, cleanup. You deal with the owners. No coordinating subs, no finger-pointing, no surprise line items.
