"Mark is very thorough and explains findings well. Took his time and when he picked up the radon tests a few days later, he took another look at the exterior as it was raining the day of the inspection. Great customer service."

"This is the third time I've had Joseph perform an inspection for me in the last three years. You will find my previous reviews elsewhere on Home Advisor. His first inspection saved me from purchasing a house with many issues that the sellers failed to disclose. They initially declared that they would not negotiate on anything, but when he was finished they were rushing to backpedal and begged me not to cancel my offer. The sale was cancelled the same day he was done with his inspection. His second inspection ended in my purchasing my current home, and after three years I remain very satisfied with the purchase. This latest inspection was done in order to renew my insurance. I was asked for a 4-point but based on his expertise, he recommended I also do the wind mitigation since it might be asked at some point. Turns out, it will be needed after all, and his recommendation saved me from having to do this twice. So I have used Joseph's services for years, and he's always delivered even if asked to do so in short notice, with time constraints, while being flexible and accommodating when it comes to scheduling the work. I haven't had reason to complain about his services yet, and I will continue to call him first whenever I require any sort of home inspection."

"They installed a Radon Mitigation System. They were very accommodating. They wanted to ensure we were satisfied with the placement of the radon fan and plumbing. We went over everything twice. They were highly experienced. Our radon level in our basement was 4.5 before the installation and 48 hours later was 3.5 and is now recording steadily at 2.5. We will probably take additional measures to improve the quality of air but a radon mitigation system is the first step. Over time we hope the radon mitigation system will drop the level even further. I would recommend this company to others who need a radon system installed."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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.

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

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.
