"Drennen fixed a faulty radon system in our home. They took a look at what was going on and were very straight forward and honest in their approach. Every employee from the office manager to the installers exhumed care and professionalism at every step. They were extremely pleasant and kind. It was very evident that they cared about their customers and doing the job right. They also installed a radon mitigation system for my elderly father and the first thing he said when I talked to him was how nice the installers were and what a great job they had done. Both of these experiences demonstrate an integrity and honest care that is hard to find these days in any profession. I am truly grateful for Drennen and will recommend them to everyone without reservation."

"Mike & This Efficient House have done several jobs for us in the past. Most recently, they did radon mitigation & insulation work in our crawlspace plus in-wall cellulose fill insulation last December. Mike and his crew were punctual, got the job done very efficiently, and were very communicative through the entire process. We have much better peace-of-mind with the radon work done, and the house was much more comfortable through the rest of the winter with the new insulation. Previously they had performed an energy efficiency audit on the house, and managed the replacement of our old hot water heater and furnace with new high-efficiency units better sized for our small house. Good experiences in all cases, and we would definitely work with them again in the future. Highly recommended!"

"Been Living here in Fort Collins for 5 years now and Brandon Strong from Strong Heating and Cooling is quite simply, hands down, the best repair/serviceman I've EVER had!!! While his work on our furnace was excellent, it was his ability to handle some curve balls, which he hit out of the park by GOING ABOVE and BEYOND what most service/repair men would have. He saved us well over $500 on the repairs AND never EVER tried to upsell us. He was very prompt on his visits and was always just a real nice guy! I don't recommend a lot and have NEVER written a review before, but I can't recommend Brandon enough, you will NOT be disappointed!!"

FAQs for radon gas testing projects in Windsor, CO

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.
