Why homeowners pick Vision Custom

A home addition contractor who shows up — and finishes.

The most common home addition complaints in Northern Virginia come down to the same three things: no clear scope, vanishing project managers, and finish work that fails inspection. We fix all three before demo day. You'll have a fixed-price contract, a dedicated project manager who answers texts, and an in-house crew — not a rotating cast of day-labor subs.

FAQs

Home Addition questions, answered.

How much does a home addition cost in Northern Virginia?

Bump-outs start around $45K. Single-room additions run $85K–$180K. Primary suite additions run $180K–$300K. Second-story additions run $250K+. NOVA labor, permits, and engineering costs run higher than national averages.

How long does a home addition take?

Plan on 4–8 months for most additions, end-to-end. Design and permitting alone take 2–4 months in most NOVA jurisdictions. Construction runs 3–6 months after demo starts.

Do I need an architect for a home addition?

Yes — every NOVA jurisdiction requires sealed architectural and structural drawings for additions. We work with licensed architects and structural engineers and include the full design package in our proposal.

Will the addition match my existing home?

Yes. We match siding, trim, roof pitch, shingle color, and interior finishes. Older homes sometimes require custom-milled trim — we handle that in-house.

Can I live in the house during the addition?

Usually yes. Most additions are sealed off from the existing home with temporary walls and dust barriers. The breakthrough to existing space is scheduled near the end and typically takes 2–3 days.

Are you licensed and insured?

Active Virginia Class A contractor license and $2M general liability. Certificates available on request before contract signing.

After talking with a few companies, we decided to go with Vision. During the consultation, I immediately felt the good vibe from the team and was impressed by their knowledge about permits and home additions. We knew right away we were in good hands and the finished kitchen and bathroom prove it.

I had a great experience working with Vision Custom Build & Remodel on a rooftop expansion and deck project. I spoke with a number of contractors but was really impressed by their design vision and the thoughtful modifications they suggested. Amir kept communication and organization tight from start to finish — we love the finished outdoor space.

We recently had an addition and kitchen extension built by Vision Custom Build + Remodel, and we're excited to share our positive experience. Our designer Kay was fantastic — he guided us through every step with patience and creativity.
