Additions in Chester

What additions projects look like in Chester

The Chester homes we work in are mostly 1900s–1950s rowhomes, with newer infill, typically brick and stone rowhomes, older single-family, and twin homes. We've completed projects across the West End, Sun Hill, and Bethel Court.

Chester's older row and twin homes often need full mechanical updates, knob-and-tube wiring, original plumbing, and outdated panels are common. We bundle the modernization into the remodel scope so it gets done once.
