"As a Realtor, Schan has done many of my clients' radon system install and they all were extremely please with his knowledge, install and his going above and beyond to make the system appealing from the exterior of the home. Many companies will not make the effort to ensure that the system does not look unsightly. Schan does and he is an expert at what he does. I would only recommend Schan to my clients!"

"When your basement floods it is a very stressful time and I am so grateful that the first phone call I made was to US Waterproofing. Jose came out right away and quickly diagnosed what happened (Sump Pump failure) and then took me through all the options -- Good, Better, Best to fix it. I ended up going with the Better option. They scheduled the work quickly and I was very happy with the professionalism of the 3 installation people that came out led by Mauricio who installed a new sump pump and a battery backup sump pump so that I have insurance in case the main sump pump fails or there is a power issue. Could not be more satisfied with US Waterproofing. I highly recommend them!"

Radon Detection and Reduction FAQs, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

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