"Tom was wonderful and extremely thorough! He explained everything as he went along and I left feeling like I really knew the ins and outs of the property. He was extremely personable and very professional. He called to schedule and follow up prior to the date of the inspection. I felt confident in him during the entire process. I would recommend him to anyone."

"Bob and his crew did a great job. From dealing with the office staff from the first call all the way until job completion I was impressed with the service. Not only that he had the best quoted price as well and while this may not seem like a big deal there were a few factors that made this impressive. First he was coming from further away than any other company, a lot further, over an hour away. Next he quoted the job site unseen and found that a portion of the work he quoted was already done when he arrived onsite so after the lab test came back showing everything within acceptable ranges he surprised me with a refund for that portion of the job that he didn't have to perform."

"This team was professional, as well as friendly and knowledgeableâ ¦gave us up front scenariosâ ¦ we didnâ t have to pay them before OR after the job was done (once the testing is done and we are SATISFIED, we are to pay the bill â ¦which was a little higher than the first company we contacted but the first company wanted payment up front and said nothing about OUR satisfaction). We were appreciative of the explanation of what was done and what WE needed to do to make sure the system was working properly. We got clear instructions on testing after installation. So far, so good! We are pleased."

Radon Detection and Reduction FAQs, answered by experts

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
