"I had significant water intrusion into my garage and a bathroom, which is underneath my kitchen, during the tropical storm last fall. There had also been some previous water damage as well. I used Angie's list deal to get mold testing done. Aaron showed up at the scheduled time and completed the testing. In a few days, he sent me the results of the testing and a quote on remediation. Fortunately the mold was minor,, however the damage was still significant so I contracted to fix the damage. The work took about three days. They used vapor barrier and fans to keep the air contained in the garage as they removed the drywall and insulation, treated the mold that they found. They replaced the insulation and put up new drywall using quality materials. Overall, the work went smooth. The workers were timely, professional and took good care of my home."

"A two-man team worked very efficiently to remove each vent cover and vacuum inside the vent openings throughout the townhouse. One man removed the vent covers while the other man vacuumed inside the vent openings. No problems with how they worked but I think there are other companies who perform a more thorough cleaning of ductwork using other methods. This company did a superficial cleaning and worked very quickly. In and out within an hour.

Radon Detection and Reduction FAQs, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.
