"Professional, punctual, knowledgeable, and honest. After I contacted him to hire him for testing he came by and offered to test, then explained how the radon level was low during warm weather. However I still wanted to test. When the test came back very low level, he offered to come back, and retest for free during the cold weather. I would definitely recommend this company to anyone needing Radon testing or mitigation."

"Brian was really friendly and professional, and you could tell he was very thorough. He explained everything in a way that was easy to understand during the inspection, and the report he sent after was super detailed with pictures and notes on all the systems in the home. I especially liked that he included a section that called out the main issues to focus on. Overall, we were very happy with his service and would definitely recommend him to anyone."

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.

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.

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

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.

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.
