Before & After Photos

ALS Radon & Environmental a local radon company in Kalamazoo completed a radon system mitigation at a residential property. A sub-slab depressurization radon system was used on this home. Schedule 40 piping was run from the basement extraction point to the exterior of the home. The radon fan was installed on the side of the home and vented above the roof line.

ALS Radon & Environmental installed a radon gas mitigation system at a residential home in Kalamazoo, MI. A sub-slab radon depressurization system was used on this home. The radon fan was installed in the garage attic and vented through the roof line.

This is an example of exterior portion of a standard radon mitigation system ran for a real-estate transaction. As always, we took time to professionally install the system so it looks great and will withstand the outdoor elements. 

Interior example of a radon mitigation system completed for a real-estate transaction. Notice how clean and inconspicuous this installation is. We always take the time and make sure we are installing our systems professionally and strategically to not only effectively lower radon levels but maintain the value of the home. 

Check out the before and after photos of a sub-membrane depressurization completed by our team. We proceeded and installed 20 mil Cleanspace Vapor Barrier throughout the crawlspace. We then completely sealed it making it airtight. Our depressurization system is connected creating negative pressure under the barrier. The radon gas follows the bath of least resistance and is safely vented up above the roof.
