Radon In Salem And Salem city
Radon is an invisible, odorless radioactive gas that seeps into homes from the soil, and it is the second-leading cause of lung cancer in the United States, behind only smoking.
Because radon comes from the ground beneath each individual foundation, levels swing widely from house to house on the same street. New homes and old homes, with and without basements, can all have elevated radon. The EPA and the Surgeon General recommend that every home below the third floor be tested. The Virginia radon office ((804) 864-8161) can point you to test kits and current state guidance.
If your test comes back at 4.0 pCi/L or higher, a mitigation contractor can install a radon reduction system, usually in a single day, that cuts levels by up to 99%.
14 of them are based in or right beside Salem; the rest travel in. 24 of them install mitigation systems and 48 test. 21 of them do both. Having the same company test and then mitigate is convenient; having a different one do the post-mitigation retest is the more independent check.

- DIY test kit, available from your state radon program and most hardware stores.
- Sub-slab depressurization, the standard system for a basement or slab home, usually installed in a single day.

Certification And Licensing In Virginia
Whether radon work requires a license depends on the state. Some license anyone who measures radon for a fee or installs mitigation systems; others leave it to voluntary national certification, so two companies a mile apart can be held to different standards. The radon guide lists where to check either one.
Certification and license details change over time, so check a company's current standing with the Virginia radon office at (804) 864-8161 before you hire.
Radon FAQ For Salem Homeowners
What Are Radon Levels Like In Salem?
Radon levels vary house to house, even next-door neighbors can test very differently. The only way to know your home's level is to test.
What Radon Level Is Dangerous?
The EPA action level is 4.0 pCi/L, at or above that, the EPA recommends having a mitigation system installed. Because there is no known safe level of radon exposure, the EPA suggests considering mitigation between 2.0 and 4.0 pCi/L as well. The World Health Organization recommends acting at 2.7 pCi/L.
How Do I Test My Home For Radon In Salem?
You have two options: hire a radon measurement professional from this page for a precise 48-hour monitor test, or use a do-it-yourself test kit from a hardware store or your state radon program. Short-term tests take 2–7 days; if the result is 4.0 pCi/L or higher, confirm with a follow-up test or move straight to mitigation.
How Much Does Radon Mitigation Cost In Salem?
Most single-family radon mitigation systems cost between $800 and $2,500 installed, with typical jobs around $1,200–$1,800. Those are national figures; we do not publish a price for Salem, because the number that matters is the one a contractor gives you after looking at your foundation. Price depends on foundation type (basement, slab, crawlspace), house size, and how the piping has to be routed. 51 companies cover Salem, 28 of them within 25 miles, and the 25 below are a selection of them. Three quotes is a reasonable ask rather than an imposition, and prices for the same job vary more than most homeowners expect.
How Does A Radon Mitigation System Work?
The standard fix is active sub-slab depressurization: a sealed pipe is inserted through the foundation floor, and a continuously running inline fan pulls radon-laden soil gas from under the house and vents it above the roofline, before it can enter your living space. Systems typically reduce radon by 80–99%, run on about as much electricity as a light bulb, and include a manometer so you can see it's working.
Do Radon Contractors In Salem Need To Be Certified Or Licensed?
It depends on the state. Some states license anyone who measures radon for a fee or installs mitigation systems; others leave it to voluntary national certification. Certification and license details change over time, so check any company's current standing with the Virginia radon office at (804) 864-8161 before you hire.
