Why Haymarket homeowners choose Vision Custom
If you’re looking for Haymarket addition remodeling, you’re at the right page. Our licensed addition remodeling contractors in Haymarket, VA handle projects of all shapes and sizes — from refresh-level updates to full gut renovations involving structural work, permits, and high-end finishes.
Haymarket homes are typically dominion valley custom colonials, estate homes, and historic old town properties, which means we plan every remodel around the realities of these floor plans — 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 — and across ZIP codes 20169.
What’s included in a Haymarket addition remodel
Permits in Prince William County
Every addition remodel in Haymarket that touches plumbing, electrical, or structure requires permits through the Prince William County Development Services. Vision Custom pulls and manages every permit, schedules each inspection, and meets the inspector on site — you never sit in a permit office.
Haymarket addition remodel FAQs
How long does a home addition take?
Most additions run 3 to 6 months from groundbreaking. Two-story additions and additions requiring structural work on existing foundations land at the longer end.
Do you handle the architectural drawings?
Yes — our in-house design team produces stamped architectural and structural drawings, then we manage the permit submission directly with your county.
Will you match my existing home's exterior?
Yes. We source matching brick, siding, trim profiles, and windows so the addition reads as original construction, not a bolt-on.
