Important Radon Testing in Your Home

Federal agencies like the U.S. Surgeon General and the EPA suggest that all homes be regularly tested for Radon Gas. This is the main cause of lung cancer in nonsmokers.


Keystone Home & Environmental Services LLC will test your home by using an electronic, Continuous Radon Monitor (CRM) over a 48-hour period.

Our special monitor takes samples from the air at preset intervals and graphs each reading. After 48 hours, our inspector will read the test equipment to determine the average.


If your home's radon level is at or above the EPA-recommended maximum level, you should consider a mitigation system. Our inspector is happy to assist you with any questions regarding the results.
