Customers say: Quick response

"Mike came out to do Radon Mitigation at our property. We had received quotes from some local companies reaching into 5 figures! Mike not only did the job for a 3rd of the cost, but the radon levels were massively reduced to proper safe amounts. High quality materials used in the work, and he completed everything in one day. He is a super nice guy, who is very experienced at what he does, straight forward, and honest. You can't go wrong, and I would definitely recommend him to friends."

Choosing the right home inspector can be a difficult. Unlike most professionals, you probably won't get to meet your home inspector before hiring them. Furthermore, different inspectors have varying qualifications, experiences, equipment, reporting methods, and pricing. One thing for sure is that a quality home inspection requires a lot of work, and a thorough inspections depends heavily on the individual inspectors effort. If you honor us by permitting us to inspect your new home, we guarantee to give our very best effort and perform the inspection as if we are buying the home ourselves. This we promise to you. We look forward to earning your business! \n

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

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.

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.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.
