I always do what i say. Never do I cut corners by using the cheapest fan, or not install something that could put homeowners at risk. I have never quoted a price then asked for more money. I install radon mitigation systems because my family has been affected by cancer. I'm proud of what I do to try and help other families.

"John went out of his way to find an ingenious way of installing a radon mitigation system in our house. He had to drill to the garage from the electric room and connect the pipe there and place a fan on the garage attic, where it took power from the second garage opener. Five years later, the system works fine and we have had no radon. Not only that but he also installed a nice sump pump before sealing the sump well, and this pump has actually saved us a lot of issues this year with the torrential rains we have had (it’s currently running every 5 minutes in November!) John did a fantastic job and for a good price as well. I asked him once to come test the system, and he said it would cost me for him to come over just for that, and he recommended I test it myself, and told me how. All this to save me money. I highly recommend John and I’m sorry I never got to write this review earlier."

Got our installation scheduled right away and blew away the tight timeline we were facing with closing approaching. I hope I only need one remediation system in my lifetime but if I ever had to use his services again, this would be the first spot I would call."

Radon Detection and Reduction questions, 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.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.
