Visitors arrive asking one thing: do you work where I live
Service area is the first question in a metro split across three jurisdictions, so answer it above everything else.
Name the places in plain text on the first screen. The District, Arlington, Alexandria, Falls Church, Bethesda and Silver Spring reads as a real answer. Serving the greater Washington area reads as an evasion, because in a market with three sets of rules it usually is one.
Say what you do not cover with the same clarity. A firm that works the District and Northern Virginia but not Montgomery County should write that down. The inquiry you lose was never a job, and the hour you save belongs to your design lead.
Put the same statement on every landing page rather than only the home page. Search traffic rarely lands on a home page, and a visitor who arrives on a bathroom page deserves the answer there.
Pair the service area with the scope you take. Full kitchen and bath renovation is a different business than a fixture swap, and stating your floor politely filters the calls that end in disappointment.
