"Rob followed up after a day or 2 to see what I thought. Based on Platinum’s customer service, I chose them to clean several rooms, upholstered furniture and large basement of my home. Henry was the tech on site and kept me informed as each room was started and completed. He also conferred with me to see if I was satisfied with an area before moving on to the next. My carpets turned out fabulous and after several weeks, not one of the original stains has resurfaced."

"Aaron was great to work with on our elevated deck project from start to finish. Safety and quality workmanship were our biggest priorities and we were quickly put at ease with how he explained the connection to the house and the support structure. He helped evaluate the site and made design and material recommendations that best suited our needs while accommodating our budget. He was patient and very knowledgeable in answering our many questions. Communication before and during the work was awesome. Very polite and professional at all times. In addition, the finished product looks AWESOME and is rock solid. Excellent craftsmanship! We couldn't be happier. For any future projects we'll definitely be going back to Clean Edge to do the work."

FAQs for radon gas testing projects in Sandwich, IL

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.
