"Wilmar was a pleasure to work with. We had them remove asbestos popcorn ceilings. His crew was very professional and Wilmar was a great communicator. He explained the process and answered all my questions very knowledgeably. The preparation process was thorough and they took great care to protect my floors, walls and carpet. I especially appreciated that they told me in advance that there would be some paint damage to upper walls from the tape to protect them so that wasn’t a surprise. Price was good and they finished in 3 days."

"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

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.

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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.
