"Bill is hands down an amazing home inspector. We hired him this past weekend and he came early, answered all of our questions, took notes down, took pictures of things that needed repairs, did a roof inspection as well as termite inspection and did everything so thoroughly that he stayed well past 4 hours. He was so nice and very knowledgeable. He truly is passionate about his job and wants us to know every detail about our future home, which is so appreciative. Thanks for all of your help Bill!"

"H&G is fantastic - extremely professional, timely, and by far the best bang for your buck. I was able to talk directly to the owner and easily schedule an emergency appointment for that same day. Mr. Garvin himself came out the the property to locate and treat standing water and mold in our crawl space and kitchen and conduct an air quality test. He worked hard and quickly to identify and fix the issue, didnâ t overcharge for anything unneeded, and even took the time to be sure we understood exactly what he was doing. Overall I appreciated their urgency, care and precision. Iâ ll be using H&G from now on!"

"Tommy, Paul and crew did an excellent job with my radon remediation and installation of a new attic stairs. They tailored the exhaust piping for my radon removal so the only thing that showed was the exhaust vent, which they painted to blend in with the roof. The test results after remediation was only 0.4 pCi/l. The very low results is a testimony for their outstanding work. They were very friendly and accommodating. They always strived to exceed my exceptions, which they did. I highly recommend Atlantic Radon."

Radon Detection and Reduction questions, answered by experts

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Installation typically takes 1-2 days, depending on the system and property layout.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
