"This is the review. Let me know this is good before I send Prompt and on time service for the asbestos removal along with safe and proper poly containment. Also 3rd party testing confirmed safe air test. The workers were in suits, masks and had ASD machines running very professional and highly recommended for any asbestos work! We are very pleased the cleanup was nice, with no debris . I would definitely hire again if needed"

"Bill was wonderful and has our highest recommendations. He answered every call and replied to every message promptly, with knowledgeable responses. He was early to the inspection, took the time not only to inspect our new house thoroughly (no rushed feel), but also answered all of our questions as first-time home buyers in a very personable manner. He even inspected the roof despite the rain! Pricing was very reasonable and included all of the work we needed (added radon and pest). His thorough report came as promised later that day, and he answered follow-up questions we had afterward. We felt confident in our decision to move forward with our home purchase because of Bill's outstanding work. It shows that Bill really cares about his work and enjoys what he does. Excellent service, thank you!"

Radon Detection and Reduction FAQs, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
