"Mat is the inspector realtors hate... tongue-in-cheek. He is extremely knowledgeable, has great attention to detail, and is very honest. If there is something wrong with the property, you better believe he's going to find it. He takes the time and does a thorough job. I highly recommend him!"

"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"It went very well, from the estimate to completion. Greg was clear, honest and direct and he cares about his customers being satisfied. The workmen arrived  on the date agreed upon, were generally neat and clean and careful about my  house. It was a big, messy job and they cleaned up well. There were a few details to finish and Greg came personally to complete the little things. For example, during the clean out and other work, a t.v. cable was pulled loose and fell between the walls.   Greg came back to fix it. He made sure I was  happy with the job. I can already notice a difference from the pebble/dirt crawlspace and the new one with the liner. I notice less dampness in the family room, and there is no more smell, even on days it is raining. I trust it will be significantly warmer in the winter.

Radon Detection and Reduction questions, answered by experts

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.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
