"Danny Wine from A2Z Inspection provided excellent customer service. He was professional, and always quick to reply. I asked a lot of questions and he was patient and thorough regarding the process. I was in a rush to book my home inspection and he was accommodating. You never know these days when finding service online but A2Z proved to be trustworthy and professional. I would highly recommend using them. Five stars for sure!"

"Frontier Foundation and Crawl Space Repair is a top notch company! Their work is timely and second-to-none. Mark inspected and serviced our crawl space dehumidifier along with our radon mitigation system. He is a true professional who went above-and-beyond, and I will definitely request him on future inspections. I feel confident in the quality work Frontier provides and strongly recommend them to anyone in need of crawl space/basement/foundation work! Thanks again, Mark!"

Radon Detection and Reduction FAQs, answered by experts

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.

Installation typically takes 1-2 days, depending on the system and property layout.

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 present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
