Radon Mitigation · Arlington, Virginia
Radon Mitigation in Arlington, VA
Arlington County sits in EPA Radon Zone 1, the highest-risk zone in the country. If your Arlington test came back at 4 pCi/L or higher, a mitigation system is the fix: a sealed suction point under the slab, a PVC pipe and a quiet fan that vents the gas above the roof. Viper Home Services matches you with certified, independent radon mitigation contractors who serve Arlington, sends your request to up to three of them, and follows up until you have a quote. The matching is FREE for homeowners; you pay only the contractor you choose.

The problem in Arlington
Radon is the second-leading cause of lung cancer after smoking, according to the EPA and the U.S. Surgeon General, and it has no smell or color. About one in every fifteen U.S. homes has elevated levels; in Zone 1 counties like Arlington County the share is higher. Most Arlington homeowners find out during a home sale, with a closing date a few weeks away and no idea which contractor to trust or what the job should cost.

Frequently asked questions
Does Viper Home Services install the system?
No. We match you with independent, certified radon contractors who serve Arlington and send your request to up to three of them. The contractor you choose does the work under its own certification, insurance and warranty.
What level of radon needs mitigation?
The EPA recommends fixing a home at 4 pCi/L or higher and considering a fix between 2 and 4 pCi/L. There is no known safe level; lower is better.
How long does installation take?
Most systems are installed in four to eight hours, in one visit. The post-mitigation test is done a few days to a few weeks later.
Will it be loud or ugly?
Modern fans are quiet, about the sound of a refrigerator, and are mounted outside, in the attic or in the garage. Pipes can be routed through closets or along the exterior to match the siding.
Are the contractors licensed?
Virginia and Maryland do not issue a separate radon license; the standard is NRPP or NRSB certification, which Virginia requires for real-estate radon work. Every contractor we match you with holds it, and we check it before adding them.
What does the matching cost me?
Nothing. Homeowners never pay us. If you want, call 1-800-455-5691 and tell us what your test showed; we will send your request within one business day.
