★ Serving Northern Virginia
When moving is not the answer, the right addition gives you the space you need without leaving the neighborhood you love. Custom Painting & Remodeling designs and builds additions across Northern Virginia, from a single bump-out to a full second story, tied in so cleanly that the new work reads as original to the house.
What we build
- Room additions for a bigger kitchen, a family room, a home office, or a primary suite.
- In-law and guest suites with their own bedroom, bath, and often a private entrance.
- Second-story additions that add bedrooms and baths on the existing footprint.
- Bump-outs and sunrooms that stretch a room a few feet where it counts most.
- Foundation, framing, and roofline work that carries the load and matches the existing home.
What it costs in Northern Virginia
Cost depends heavily on scope, foundation work, and how the addition ties into the existing structure. As a local guide, home additions in Northern Virginia generally run about $200 to $400 per square foot, with simple bump-outs on the lower end and second-story additions or suites with full kitchens and baths on the higher end. Site conditions, roofline changes, and finish level all move the number. After we see your home we give you a fixed, itemized quote, so the price is set before demolition.
How it works
- Free in-home consultation and measurements, with a clear estimate.
- Design and engineering, where we lock the footprint, structure, and finishes.
- Fixed written proposal, so the price is set before demolition.
- Permitting and construction, managed by one accountable team.
- Walkthrough and warranty once every detail is right.
Permits
Additions change the footprint or structure of your home, so they require a permit from your local Northern Virginia building department and usually a zoning review for setbacks and lot coverage. We prepare the stamped drawings, pull the permits, and manage every inspection, so your renovation stays on schedule.
Frequently asked questions
How long does a home addition take?
Most Northern Virginia additions take three to six months from permit to final walkthrough, depending on size, foundation work, and whether a second story is involved. We give you a realistic schedule with your quote.
Will the addition match my existing house?
Yes. Matching siding, roofline, trim, and interior finishes is the whole point, and it is where a contractor with a painter’s eye for detail earns their keep.
Are you licensed and insured?
Yes. Custom Painting & Remodeling is a licensed and insured Virginia contractor, and every job carries our workmanship warranty.
Depending on your goals, an addition can pair with a basement remodeling project for even more living space, or make sense alongside a full whole-home remodeling.
