Q: Why is radon gas abatement necessary for homes?

Q: How long can you go without a radon fan?

• <div><p>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.</p></div>

Q: Is radon mitigation worth it?

• <div><p>Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home&rsquo;s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.</p></div>

Q: What is considered a safe or dangerous level of radon?

• <div><p>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.</p></div>

"RADON SYSTEM WAS NOT WORKING. (Installed by another company years ago). The phone contact was pleasant and efficient. The Technician came on the agreed day and the agreed time: he explained what was wrong, explained the options, then repaired the system so it is working better than it did when first installed."

"I had done two separate radon tests and knew the level was high. Bill came to evaluate where to place the system. He gave me a rough cost and time it would take for the install. He was able to schedule the install within a week. He arrived when scheduled. They did a very thorough job and cleaned up well after the install. It was hard to tell they were here. Very professional. The only knock I would have is that because they are quite busy, it is difficult to get an initial visit as Bill does the evaluation himself. You may have to call a few times and it was a challenge to pin down.
