"This was a great experience from start to finish. They arrived on time got and got the work done with zero mess even though this involves drilling a large hole in the basement floor. The system did what it’s supposed to do and reduced radon levels to almost 0. I am very happy with this company and would highly recommended them.The price was great too."

"Corey is great to work with. He gave an accurate estimate, was quick to respond to our messages, and did a good job installing the radon mitigation system. Within 24 hours, our radon levels dropped from 15+ pCi/L to less than .5 pCi/L (and still dropping). Corey also ensures his work up to a year after install for free, which gives even greater peace of mind and value for our purchase."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
