"Simply Radon was great. They were very responsive, professional and friendly. I bought a radon detector to test our basement and got readings well over 4 pCi/L. After Simply Radon installed a mitigation system it dropped to below 1 pCi/L. I strongly recommend them for anyone considering radon mitigation."

Residential and commercial property inspections, and infrared thermal imaging services.

"Bill was excellent! He was at the house when we arrived and was already walking and viewing the exterior. He was very knowledgeable, and patient in explaining what he was looking at and why. The house had some very serious issues that without his expertise, would have devastated us financially, down the road. We have used other inspectors in the past, but we will only call Bill at BC Warner Inspections from here on out!"

Radon Detection and Reduction questions, answered by experts

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.
