"They were prompt, efficient and courteous. They called to let me know they were on their way and cleaned up everything when they were done. They were supposed to explain something to me about some monitor after the installation, but they forgot. They did walk through how to do the radon test in another week. they also gave me a senior discount, which was definitely appreciated. Otherwise, their pricing was pretty much in the range with the other estimates I received."

"Zach Shipley of Clear Environmental took on the task of removing my extremely large inground swimming pool, filling the cavity and resodding the lawn. He and his crew were very professional in all aspects and he was very "hands-on" throughout the entire process. He was on-site for delivereies and to oversee the work and to keep me apprised of everything that was being done and how the job was progressing. It was a monumental job and he made it as painless as possible at a very competitive price. I would highly recommend Clear Environmental to anyone with a home or commercial project."

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.
