Radon Gas Mitigation Photo Album: Radon Mitigation and Crack Repair, Milford, NH

A homeowner residing in Milford, New Hampshire, has been living in their house since 2018. Recently, they noticed a PVC pipe in their basement that appeared to be a passive radon system. Consequently, they decided to get their home tested for radon. After testing, they discovered high levels of radon, between 6.7-10 pCi/L, which exceeded the recommended amount from the National Radon Defense. As a result, they contacted EFS to design and install a radon mitigation system in their home. The homeowners also requested the sealing of the cracks in their basement.   Josh Phillips, the Design Specialist from EFS, met with the homeowners and designed a suitable radon mitigation system for their home. He also recommended sealing the foundation cracks with NexusPro Crack Repair. The homeowners raised a concern about the air quality inside the main living space, and so, Josh suggested an Aspen Air Purifier.   The Installation team, led by Steven Dumais, began by plugging in the Aspen Air Purifier into the main home. Then, they created two extraction points for the Radon Mitigation System in the basement. For this, the team used a 3" core drill to make a circular hole in the slab and installed a 3" PVC pipe to link the two extraction points. The PVC pipes carried the radon-filled air to the radon fan, which the team installed on the exterior of the home. They then vented the system with more PVC piping above the roofline of the home. After hooking up the power to the fan, the system began to draw up the radon from beneath the home and direct it out and above the home, where it could dissipate into the open air. Finally, the team sealed the cracks in the basement slab using NexusPro, sealing up to 25 feet of cracks to prevent radon from seeping up through the slab.   The homeowners were pleased with the installation of the Aspen Air Purifier, Radon Mitigation System, and NexusPro into their home.
