Additions in Dover

What additions projects look like in Dover

The Dover homes we work in are mostly 1950s–1990s suburban, plus older downtown stock, typically ranches, split-levels, and two-story colonials. We've completed projects across downtown Dover, Mayfair, Wild Meadows, and the Camden-Wyoming corridor.

Dover is a healthy 1-hour drive from our Wilmington base, we routinely take Kent County projects and bring the same crew, same materials, and same quality standards we run in northern Delaware.
