Radon Testing Companies Near Ashburn

Radon Inspectors In Your Area

Radon is a colorless, odorless, and tasteless radioactive gas that can't be found without special equipment. Homeowners exposed to the gas are more likely to develop lung cancer and other illnesses over time, so it's important to have a professional tester check the air in and around your home to prevent future medical problems.

Professional inspectors use equipment which can detect small pockets of radon to determine whether a property has a safe amount or not. To find a company in your area, enter your zip code. HomeAdvisor will connect you with radon testing companies near you.

"Great service..... I mean....who shows up at 8 p.m. on a Sunday night! I was in a hurry and only had a few days to get this done... he said no problem and was at my house within 30 min setting up the test kit. Well.... he is a former Marine....so getting the mission complete is in his blood."

"After living in our home almost 25 years, we recently learned that radon has become more of an issue in our neighborhood. We did a couple of tests and found that our house needed remediation. When googling "radon remediation" Home Advisor came up. I quickly contacted (or was contacted by) 3 companies. Boulder Edge was willing (even preferred) to come out for an estimate - to look at the setting and determine location for the system (we were concerned about placement because out basement is so full. Tom found a suitable location and we set installation for the next week. His workers showed up and did the work neatly within a couple of hours. Post-test revealed radon levels well below EPA guidelines. The cost was reasonable in comparison to other estimates. Very satisfied with this company and highly recommend their service. "
