"They were not satisfied until my radon levels were pretty much annihilated! Very clean install, came back to measure levels, were still a little higher than expected, so came and dug deeper and put in a different fan and that did the trick! Very reasonable pricing and great communication."

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

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
