Radon Removal and Crawlspace Encapsulation

See the before and after of a crawlspace our team recently encapsulated. The encapsulation was part of the radon depressurization system we installed to mitigate the radon. The CleanSpace liner is 20 MIL thick with an antimicrobial coating and really improves the air quality and overall environment of not only the crawlspace, but the home. 

Sub Membrane Depressurization in Lansing, MI

Before and after of a full crawlspace encapsulation for a radon sub-membrane depressurization. What a transformation! This system lowered the radon levels significantly and greatly improved the comfortability of the home.

Sub Membrane Depressurization - Kalamazoo, MI

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. 



Radon Sub-membrane Depressurization - Berrien Springs, MI

This radon mitigation was a combination depressurization. We encapsulated the crawlspace and created negative pressure under the membrane as well as the basement slab. 

ERV Installation - Galien, MI

Our client not only had concerns regarding elevated radon levels, but the indoor air quality of the basement as well. They decided to have us install an Energy Recovery Ventilator to bring fresh air in and stale air out. ERV's bring filtered fresh conditioned air in and are set at a slight positive pressure. This improves the overall indoor air quality and helps to lower radon levels as well.
