Radon Mitigation in Fairfax, Virginia
Fairfax County sits in a moderate radon zone. Sub-slab depressurization systems reliably reduce elevated radon levels — we install and verify with post-mitigation testing.
Radon mitigation lowers the radon concentration in a building's living space below the EPA action level of 4.0 pCi/L. The standard technique is sub-slab depressurization — a fan continuously draws air from beneath the slab and exhausts it outside, preventing radon-bearing soil gas from entering the structure. Other techniques (crawlspace depressurization, sub-membrane suction, block-wall depressurization) apply where the standard system isn't appropriate.
Fairfax County has elevated radon potential across most of its geology, and most homes test high enough at some point to warrant mitigation. We install sub-slab and crawlspace systems on residential properties throughout the county, often as part of pre-sale negotiations or after a homeowner-initiated test. The installation is a 1-day scope; post-installation testing 48 hours after commissioning confirms the system is achieving the target reduction.
