"After learning that radon levels in my home was higher the recommended levels, I reached out to Eddie. He was very easy to work with and was very patient with us. In the end our radon levels are very low! We are completely satisfied with the services provided. Eddie went above and beyond for me. Thank you!"

"He was fantastic. We have purchased 4 homes and have never had such a complete inspection. He did not leave any stone unturned. The house was built in 1906 and had a great many issues. Chris was extremely thorough. His office sent us the contract ahead of time so that we could review it. He was on time and stayed for about 3.5 hours. The report his submitted was complete and quick. It inlcuded a picture with each property comment to illistrate his point. Overall, excellent. <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."

"<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 />"

"Overall, the company is very professional, knowledgable and friendly. The technician came late about 45 minutes, but he was accessible by mobile. The initial testing didn't test for asbestos due to some miscommunication, but Environcheck made good by discounting the actual asbestos testing. They were also good about responding back in a timely manner and provided all the documentation and results via email as well as mailed copies of the receipts and test results."

"Even before they came to test, Chuck spent quite a while on the phone with me personally just answering questions and giving me an idea of the process. He was very honest about what to expect and the pricing. They were very quick in responding to my call. They were able to schedule a visit the very next day, on the weekend.  The visit went exactly as described by very professional servicemen.  Not only were they well informed, but also recommended that I call the homeowners insurance as a claim.  They were very quick about the results and Chuck even called me personally with the results and some recommendations.  He even was very conscientious to save us some money by cancelling some testing at the lab that wasn't needed because of the positive result. I would highly recommend them to anyone. <br />"

FAQs for radon gas abatement projects in Agoura Hills, CA

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
