"Wish I could leave 0 stars. Save yourself the headache and DO NOT HIRE this company to do your home inspections! Michael missed over 4 major natural gas leaks in an outdated gas line as well as major bathroom plumbing issues. Bathroom now needs work because of old galvanized plumbing that is mixed with copper and PVC leaking into crawlspace. Michael reported that all plumbing was copper and indeed there was not any galvanized plumbing. False! Repairs exceed over $8,000+ worth of parts and labor for both of these projects. Even though this was a major bargaining/repair oversight prior to closing, it could have been much, much worse. Me, my friends and/or family could have been severely injured in an explosion. Someone could have even died from this negligence! When I called a plumber to check out gas smells, there were leaks so bad the soap bubble tests looked like something out of a science fiction tale. There was absolutely no apology or attempt to apologize or to correct the situation. Metro Inspection could have said something like, "We are so sorry. What can WE do to make this right!?" Most companies do everything they can to help their customer. That didn't happen. They simple ignore me and contacted me only when I mentioned I would be leaving behind negative reviews. When Mike contacted me, he said things like, "You [and your realtor] knew I was not going down in the crawlspace, the gas leaks weren't there before there happened after the inspection, and we are not responsible for this because you know that we checked." At least two of the gas leaks occurred outside of the crawl space, actually in the garage, something that was lazily and neglectfully overlooked. They leaks weren't even in the crawl space as Mike argued. Customer service doesn't exist with this company and they simply blamed me and my realtor instead of correcting the problem. I feel rotten, upset, and extremely disheartened after the phone call. I requested that the gas line be paid ($3,900!) as well as a refund as a result of this company's incompetence and negligence. I requested that Metro Inspection contact the warranty service and the plumber to HELP ME OUT and get this sorted out as the warranty is only paying $500 of this bill, supposedly. This didn't happen either. No one helped me. To boot, when I requested a refund from Metro Property Inspection, they sent me a bunch of paperwork with legal jargon on it saying things like omitting liability in order to receive my refund back. That won't be happening. I am planning on holding them responsible. Absolutely abhorrent, vile, and repulsive business practices from this company. I have never in my life been blamed as a customer for a company's oversight. A major gas leak and it's the customer's fault?! Save yourself the nightmare these people will put you through and DO NOT HIRE THEM! I am a full-time educator and I have been dealing with this for months now when I come home. **Go someplace else whatever you do!! DO NOT HIRE THIS COMPANY!!!!!!!!!!**"

FAQs for radon gas testing projects in Saint-louis, MO

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.
