"They came back and checked on it when the levels weren't quite what they should be. I only have good things to say about them. They were very professional and knowledgeable. They seemed to have a lot of information about radon and how to have it removed from our house, and keep the levels down. The price was reasonable."

"I received 3 quotes from 3 different company's who are certified in radon and Mason Dixon was the highest by $170.00 plus they have a gravel clause in their contract while others did not which could cause the price to go up another $500."

"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."

"If you’re looking to get any type of inspection or home services then look no further. I recently became a customer of Justin Ake after trying to get my soon to be home inspected. Rick was dispatched to the property and went above and beyond, both explaining the inspection process and showing me key points in the houses plumping and drainage systems. As well as providing information on other tests and services the company performs. I don’t normally write reviews, but I have to say this is one business that takes pride in their trade."

Radon Detection and Reduction FAQs, answered by experts

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.

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.

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

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.
