Service areas
Onyx works throughout Northern Virginia and Washington DC. Estimates are free everywhere on this list — if you are just outside it, call and ask, because we often can.
From Clifton to the District
Shaded areas are the counties and independent cities we work in. Towns like Vienna, Burke, and Fairfax Station sit inside Fairfax County, so they are marked with pins rather than their own outline.
