"Came the same day posted job. Cleaned the vent and dryer still didn't work. "I don't fix dryers I just clean them." Charged us $225 and dryer still doesn't work. How about charging less since it wasnt fixed. Very disappointed."

"Andy showed up having already done some research on our house, i.e. when our house was built. He looked at our crack, did a little digging to see how deep and how hard the concrete wall was. He then explained his process in a very clear manner and showed samples of the epoxy that he uses. He also showed the tools that deliver the epoxy into the crack. He had several other jobs, but kept us apprised of when he could begin our job. He showed up when he said he would and did a very professional job, cleaning up after each time. Andy was very personable and great to work with. And the price was a little less than I thought the job was going to be. Highly recommended!"

"John, Bill, and Michelle worked very hard and effectively to remove extensive mold in the basement, and mold throughout the rest of the house. The project took many days. These workers were genuinely concerned about the health and comfort of the family member who remained in the house throughout the project, and were excellent about communicating with the family about what was planned and accomplished for each day. We recommend JP Improvements! This is a trustworthy company with extensive experience in mold remediation."

"We have had such a wonderful experience with Certi-Dry. They were responsive, professional, great communication, and - above all else - patient with us as we figured out what was going on with insurance. We used Certi-Dry both for mitigation of flood damage and rebuild of our finished basement. The sub-contractors that they hired for dry wall, flooring, painting, and electrical were also phenomenal and I appreciated the input of the project managers assigned to our jobs. Great company - would suggest them to anyone and would happily use them again (though really really hoping we never have to!)."

FAQs for radon gas testing projects in Madison, WI

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
