"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!"

"We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them."

"Ray and Jacob came right out, quickly diagnosed my problem, and did exactly what they needed to fix it permanently. Super competent and really nice guys (Go Seahawks!). Ray also did a full inspection of my crawl space and attic for free as he knew I was planning to put the house on the market. Ray is certified for both mold and pest control and does not mind getting dirty to do a thorough inspection. I would give ten stars if I could!"

Radon Detection and Reduction questions, answered by experts

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

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.

Installation typically takes 1-2 days, depending on the system and property layout.

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
