"Radon 1 did a great job. We wanted to have our existing radon mitigation system removed as it was right by our new screened in porch and have a new one installed in different location in our home. The crew removed the old system and installed the new system in an area far from our screened in porch. The installation was done in an expert manner, the crew were respectful of our property, quiet, clean, wore masks and cleaned up after themselves so you would never know they'd been there, all in less than a day. The pricing was competitive, we feel like we got a fair price. I would hire Radon 1 again."

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

"It went very well. Although the situation itself is quite distressing the team helped us by answering questions, working quickly, carefully, and by removing the debris daily. The post mold air sample test showed they had done the job of removing mold successfully. They worked very hard every day until the job was done and treated our personal belongings with care as they cleaned, moved or removed them. Their team was pleasant to be around and trustworthy to be in our home when we were not. I would recommend them highly."

"Excellent service. Discovered mold from Hurricane Irma. EcoStrike was very prompt in coming to evaluate, arrange for testing, formulating a mold remediation plan and executing the plan. All work was done very professionally- very neat and thorough. Helped me file my insurance claim as well. Would highly recommend them."

"With the recent snow melt and the rain we are having this may be a timely recommendation. I hope you don’t have this need, but if you do I would like to recommend Master Service Company. We had at least six estimates for waterproofing our basement and although not nearly the cheapest, we were impressed by the presentation and the personnel and low key sales approach. So, we hired them! The work was done last week and again we were impressed with the crew doing the work, the care given to hold down the dust created, the quality of the materials used, and the willingness of the crew to keep us apprised of the job as it progressed. The was great care given to cleanup of what is a very messy job. We waited until the repair had been “battle tested”, (and this inclement weather has certainly accomplished that) before writing a recommendation. We could not be more pleased at this point. Again I hope you don’t have the need, but if you do give Mr. Jeff Russell at Master Service a call. Contact: Jeff Russell 317-720-3288."

FAQs for radon gas testing projects in Chattanooga, TN

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.
