"My good friend recommended me Palm Construction on my roof replacement. I also contacted some other recommended roofing contractors and offer from Palm Construction was very acceptable. Lee and his crew started roof replacement soon after we signed a contract. Lee was very professional, honest and helpful. His crew kept working area clean as possible and they finished my roof quick and on time. The roof passed inspection and it looks great. I would highly recommend Palm Construction!"

Radon Detection and Reduction questions, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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’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.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.
