Your Four Corners Radon Experts:
Reliable Radon Mitigation Solutions for a Safer Home Environment
What Is Radon?
Radon is a natural radioactive gas that forms when uranium breaks down in soil, rock, and water. It is colorless, odorless, and tasteless, so you can’t see or smell it. Radon gas can enter homes and commercial buildings through small cracks in foundations, crawl spaces, sump pumps, and other openings.
Once inside, radon can build up to dangerous levels. Breathing high levels of radon over time increases the risk of lung cancer, making it the second leading cause of lung cancer in the U.S.
Because radon has no warning signs, professional radon testing is the only way to know if your home, office, or business is affected. If high levels are found, radon mitigation systems can quickly and effectively reduce radon concentrations, creating safer indoor air and protecting your health.
For accurate radon testing and mitigation services, trust certified professionals who use the latest technology and follow EPA and NRPP standards.
At RMX, we are your dedicated Four Corners Radon Mitigation Experts!
