"David, Veronica and Maria we're pleasant to work with, Upfront and direct with all Communication. They also recommended a Clearance Testing Facility which was great, they made the Clearance appointment for me and the company called to schedule. David and his team where very profession, I've dealt with quite a few contractors and project managers and they did a fantastic job. David gave me his word that it will pass, and it did due to his expertise, knowledge and his Team. I thought his pricing was extremely fair as I have dealt with this problem in another area in the household due to lack of engineering integrity, I would definitely recommend AM:PM Restorations & Construction Inc. to friends and family. Don't hesitate to call and have them give you a quote."

"not that great. basically paid $99 to get an estimate. included cleaning roof and minimal repairs. took a while to get appointment, and then when they came, they didn't even do the work! gave a really big estimate and then re-seheduled to have someone else do the work. they wouldn't totally replace the roof, gave different estimates to repair, I went with a different company to do a full roof rplacement."

"I've been planning remodeling my home for years, i finally decided to commit to it and called unique. my friend said they did great work in her home. i met with the same contractor and i really liked him. he spent 4 hours with me and went into detail about what he can do and how to bring my ideas to life.
i decided to move forward and start the work. the project took about 5 weeks to do everything. they started on my bathroom and i was scared at first when i saw everything being ripped out but see it come together is amazing. first the floors vanity and shower. they finished the bathroom in a little over a week. my jaw dropped when i saw the finished result.
i couldn't wait to see the kitchen done. everyone was really nice the workers covered everything. and cleaned up after they were done. i would definitely use them and refer them to anyone i know."

FAQs for radon gas testing projects in Bryn-mawr, CA

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.
