"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"Steve examined the concrete slab - tested for moisture.  He also reported the potholes created during removal in slab be filled in before laying out the wood flooring.  We needed this inspection to have the work to be done properly. <br /> He also gave us a lot of helpful feedback which left us feeling confident on how the work should be done. <br />"

"Mike Cantor (20/20 Advanced Property & Mold Inspection) was referred to us by a family member when we recently brought a home. He is the absolute best, most thorough, and professional inspector we have worked with. Mike responded immediately when we contacted him for a home inspection that we wanted done ASAP because of our short escrow time. We were able to set up the inspection in the same week. Mike arrived early on the date of inspection around 8:45 am (start time was 9:00 am). He requested about 7 hours to perform the inspection which caught the owner and realtor both by surprised as most home inspector only gave a cursory 3 hours inspection. Mike was meticulous in his inspection and took time to points out many aspects of the house's construction, remodeling, and reconstruction that we were unaware of. He was extremely detailed in his inspection and documentation with videos, still photos, and even drones (to inspect the roof). Mike was still going strong around the 7th hours which irked the seller/ realtor but was extremely favorable and reassuring to us when we are making such a large purschase/ investment. Mike is a little bit more expensive than your run of the mills home inspector but he is worth every pennies and more. He ended up discovering multiple issues with our house that were not apparent to us on our examinations. We ended up negotiating with the owner to reduce the sale price by $40,000. Mike continued to help us with recommendations after the completion of the inspection on vendors (termite, landscaper, roofer, etc) who he felt were reliable. We can honestly say that Mike Cantor truly loves his work and he is the only inspector we are going to use or recommend going forward. Can't thank you enough Mike."

"The deal was beyond disappointing.  The representative spent a great deal of time explaining the 'deal' was deceptive in that you had to read the 'small print' to realize that this inspection didn't include any testing.  Test would be necessary of assess the hazzard level and each room would require multiple tests costing from $75 to $125 each.  We focused on one wall in one room and he took a tape sample of the mold on the wall.  I paid the additional $75 for the test and did receive a 'report' with some information information about the mold. <br />"

FAQs for radon gas testing projects in Seal Beach, 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.
