Looking for home addition contractors near you in Haymarket? Vision Custom Build & Remodel is a licensed Class A Prince William County contractor that designs and builds bump-outs, second-story additions, primary suites, sunrooms, and in-law additions across Haymarket and the surrounding area.
Why Haymarket homeowners pick Vision Custom
Haymarket homes are typically dominion valley custom colonials, estate homes, and historic old town properties — which means every addition has to be designed around the actual floor plan, foundation, and roofline of your house, not a generic template. Haymarket homes near the Bull Run Mountains are frequently on well and septic with large unfinished basements — basement finishing here almost always involves an egress window and a dedicated HVAC zone. We size both correctly the first time.
We serve every Haymarket neighborhood including Dominion Valley, Regency, Sheffield Manor, and Old Town Haymarket — across ZIP codes 20169.
