"Exceptionally knowledgeable professionals with a service mindset. My office and storage building was flooded from a burst pipe last winter (2021/2022). I called up Affordable Restoration and they helped me through the whole process. They also referred me to a fantastic public adjuster who took care of the whole claim for me. I was impressed on how knowledgeable the Affordable Restoration crew was on not only the flood aspect but also on how to work best with my insurance company. They took the time to educate me throughout the whole process on water, mold, mitigation, restoration and the claim process. After my initial meeting with them, I felt like I was an expert on these topics. This gave me a lot of confidence in working with my insurance claim. It was a breath of fresh air to deal with a contractor that actually cares about you and takes the time to listen and address all of your concerns. Their crews did a great job. They always showed up on time, constantly monitored the site conditions and left the site cleaner than they found it. I'm confident that my building was restored properly and is safe for future use. I would highly recommend working with them."

25 EMPLOYEES NO SUBS.

"Excellent company. Iwas freaked out and they calmed me down (call them before you lose sleep!) It's not as bad as it seems. Showed up right on time. Gave an excellent consult that didn't feel rushed nor about just making money (instead.. doing it right!). The actual remediation (all the dry wall in the bathroom, cutting new electrical holes, etc was done to perfection with a clean air test and no debris. They respected HOA rules and they got all this scheduled after permits. It was a seamless stress-free process and ironically it was also the most affordable."

Radon Detection and Reduction questions, answered by experts

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Through air sampling devices and surface swabs in key areas of concern.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
