"Ron came out to inspect my master bathroom tub/shower & closet for mold remediation. It took approximately 3-4 days for the mold remediation to be completed. For all extensive purposes the mold remediation appears complete. The project went downhill when Ron referred me to Bluebonnet Renovations LLC (Javier & Daniel) to perform buildback. Javier is the primary owner & was not present during the entire project, his workers performed terrible work.They did not grout & caulk correctly,chipped tile & incorrect shower pan install. I got a second opinion on the shower and they did a flood test yesterday. It was discovered the shower pan was not installed correctly b/c the shower started leaking.Bluebonnet also put grout in the drain & the cover can't be removed. The brand new shower cannot be used. I would not recommend using Ron's contractors unless you want to go through the stress of poor workmanship, lack of communication & a shower that does not include the customer's preferences."

"I have a very dangerous situation with my foundation in the front of my house. I hired these guys to tell me how to tell a contractor to fix the problem. When they came out to inspect, I showed them the problem and they agreed, it was a real problem. Later, they send a report back that completely ignores the very real problem I have. Instead, telling me to fix the back of the house that is no problem at all. Trying to ask for further assistance, they said they did what I paid them for."

"I found Hayden on Angi and I'm so glad I did. We had a bad situation where both of our bathrooms were leaking and mold was growing in several locations. We received a mold protocol and got a few estimates from well-reviewed restoration services but Hayden Restoration won our business for a few reasons. Brenton, the owner, came out and found the sources of the problems that others hadn't bothered to find. He clearly explained their process for remediation and their estimate to our satisfaction. Other bids treated us like a spreadsheet with no comprehensive understanding of the layout of our house or the unique remediation needed, but Brenton's estimate was clear and self-explanatory. I could tell Brenton had a ton of experience with all sorts of situations and won our trust when we were feeling overwhelmed with the prospects of moving out of our house and needing to demo both bathrooms. When the process began I could tell his team was taking great care of our house despite the extensive demo - all areas were properly contained and it was very clean. Brenton worked with our mold inspector and made sure we passed the final inspection. And initially we didn't want to go through insurance but when we changed our minds Brenton jumped at the chance to help us with the adjuster's questions and inspection. We are truly so glad that we chose Hayden Restoration and wish we'd found them sooner. When you are in a rough spot with water damage, do yourself a favor and contact this team!"

FAQs for radon gas testing projects in San Antonio, TX
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.
