Before & After Photos

See the before and after photo of a radon extraction point. This ties into the drain tile system and creates negative pressure throughout the drain tile system. The radon gas follows the path of least resistance and is vented out and above the roof.

Here is a before and after shot of an exterior radon fan. Our team uses Premium Festa Radon Fans. We include a radon system muffler and fan moisture guard (10 year warranty) on all radon reductions systems we install. 

ALS Property Associates installed a radon mitigation system at a residential property in Caledonia, MI. A sub-slab depressurization radon system was used on this property. Schedule 40 piping was run from the extraction point in the basement to a crawl space. From the crawl space schedule 40 piping was run through the main level wall and to the above attic. The radon fan was installed in the attic and vented through the roof.

See how we professionally ran the radon vent piping in the garage to the attic. This radon reduction system can not be seen from the exterior of the home except for the roof vent. The piping in the inside is retrofitted, but looks as if it were part of the home. 

In Byron Center, MI, radon levels in homes can pose significant health risks, with elevated levels detected at 6.3 pCi/L in one particular residence. The homeowner was understandably concerned about the potential dangers associated with prolonged exposure, as radon is the second leading cause of lung cancer after smoking. Recognizing the importance of addressing this issue, they reached out to ALS Radon for assistance.

The mitigation process involved installing two extraction points—one in the basement and another in the newly added crawlspace—efficiently connected through a pipe that ran to the garage and up to the attic. A Festa radon fan was installed in the attic of the garage, venting the radon safely above the roofline, where it would not re-enter the home. The results were remarkable, bringing the radon levels down to just 0.4 pCi/L, significantly reducing the health risks for the family. If you’re worried about radon in your home, consider having it tested and taking necessary steps for mitigation. Here, you can see the before and after photos showcasing the effective installation of the radon depressurization system. Reach out to ALS Radon today to protect your family from radon exposure.
