Customers say: True professional

"Jeff and his folks were a pleasure to work with. His communication regarding any delays or other issues is excellent. He is also great at answering followup questions that I have about how the system is running. It took our radon readings down to nearly zero from an alarmingly high value. We were hovering below 4 pCi for many years, but then our crawlspace was sealed and insulated and it soared in the living space. (The crawlspace itself was 20 pCi). Highly recommend."

"We recently bought a house and knew we needed some basement waterproofing. We went to Sure Dri because of the Angie's List reviews. And Keith Martin and his staff were great! Keith was very responsive if I had any concerns or questions. He walked me through the process and seemed to genuinely want to make sure what my options were before deciding on an interior French drain. His staff were very fast & professional (& kept the work area super clean). They even cemented an old drain to secure it and move the new sump pump to a new location with no extra charge. He guarantees his work and I highly recommend Sure Dri."

"The energy audit surfaced some significant issues. That's what we wanted. Shelter Alternatives presented a bid for the job, which seemed high. We are checking with other contractors to complete the work."

Radon Detection and Reduction FAQs, answered by experts

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

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.
