Home Improvement Contractors in McNair, VA

The median home in the community of McNair was built in 2003, newer than the U.S. median of 1980 and newer than the Virginia median of 1984. That is newer than the Fairfax County median of 1983.¹ A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Most of McNair's housing is recent: only 4% of units predate 1980 (U.S. 50%) and 26% were built since 2010. The largest single share, 36%, dates from 2000-2009. That makes it an older stock than Fairfax County as a whole (44% built before 1980).¹ On houses from the 2000s, the common first-time jobs are the first roof replacement, original water heater and HVAC, and warranty paperwork on anything still covered.

The median owner-occupied home in McNair is valued at $595,800 (ACS), above the Virginia median of $383,700.
