"Chris was very professional on the phone and it surprised me that, for such a low price, I was getting as much as I did! MA CARRES is a FHA 203k qualified inspector (though I only hired him as a home inspector) AND a Realtor so I got a little bit of everything when he and his employee came. The fact that they are retired firefighters was a bonus as I had some questions about darkened wood and they let me know where the CO2 detector should really be located for best effect. I definitely will use MA CARRES in the future!!"

"I have zero complaints about our tech, Jack. He was thorough and communicative! We have a system installed through the roof and he was able to paint the exhaust pipe to match the shingles. The front office wasn't as great. We had to schedule a follow up visit because the initial install wasn't going to work. Unfortunately they never put me on the schedule the second time. So my install day came and went but we didn't hear anything from Swat. I calle the next day and no one knew what I was talking about. Our account manager (Brian) was very apologetic and offered to take some money off our install because of the confusion and the fact that there were no available appointments until August 11th. Luckily they were able to add me to the top of their cancellation list, so we ended up with a system just 3 days later. I appreciate their willingness to make it right with me. I would reccommend them to others looking to have a radon abatement system installed."

"Things went well. We had a poor sales experience due to a previous salesperson that did not fully disclose the situation I would experience, however Floodbusters did make the situation right and warrantied the product to ensure that my experience moving forward was the best it could be given the complexity of my basement situation. They continue to work with me and believe me if you have any situation like I do in regards to Iron Ore and the devastation it delivers to your waterproofing system, this crew through my experience is the team now to hire."

"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

Radon Detection and Reduction FAQs, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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