"I had a pipe burst in the basement of our rental property, Flood Crew was referred by our realtor. They arrived quickly after the pipe was fixed by our plumber, demoed, and dried out the areas, even handled packing out our furniture and placing carefully in a pod storage while the work was being done. They did mold testing and made sure everything was safe, the best part was that they dealt with the insurance and we didn’t have to do anything."

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 is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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.
