"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."

Radon Detection and Reduction questions, answered by experts

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.
