Radon is a dangerous, radioactive gas that can seep into your home through your foundation. Recognized as the second largest cause of lung cancer in the United States, this substance is scary stuff.

When you purchase a new home, radon testing is frequently included in a home inspection. If your home has not been tested for radon in recent years, you might want to consider having a test performed, especially if you are now occupying a lower part of your home such as the basement. Weatherseal is a certified radon test and mitigation company.

Customized Radon Mitigation Services

Like our other services, we have no one-size-fits-all approach to radon mitigation. We strive to find the lowest-impact method to keep radon out of your home. Sometimes, we can resolve the issue by properly sealing air gaps in your foundation or building envelope.

Often, radon requires a ventilation system. We can install an energy regulation ventilator to help control airflow and keep radon out of your home. We also can install below-slab piping that works in cooperation with your home systems to provide cleaner, safer indoor air.


“James, Lesley, Michael:

Your radon remediation was effective.

Post-mitigation radon tests came back well below the maximum safe threshold of 4.0 pCi/L, with levels indicating little short-term risk:
0.6 pCi/L (finished part of basement)
1.3 pCi/L (unfinished part of basement)

This is a big improvement over the pre-mitigation numbers, which were way over the maximum safe threshold:
7.6 and 9.8 pCi/L (finished part of basement)
16.6 and 19.1 pCi/L (unfinished part of basement)

Thanks again,
Greg S.”

Many Thanks! and Congrats to your team, Wilson. I'd be delighted when time allows, have Weatherseal go over every INCH of this old house. There are many areas that lack proper insulation and I'd be more than happy to identify and and "fix" as many as possible. A grateful, warm-- Carla H.
