Radon Mitigation Before & After Photos

Basement slabs will have cutouts to provide tubs access to sewer lines.  These cutouts have exposed soil and are radon entry points into the home. We fill these areas with expanding foam to seal it off.  

This crawlspace a damaged vapor barrier that covered the dirt floor only and did not seal against foundation wall.  We installed a new vapor barrier and sealed against the foundation wall.  Note: the after photo shows the new vapor barrier installation prior to installing the radon riser and returning the insulation to foundation wall. 

In Colorado Springs, CO, a homeowner contacted Purple Mountain Radon after their recent radon test revealed elevated levels in their basement, even though previous tests years ago showed safe results. The basement, which includes bedrooms, a family room, and a basement office, had radon entering through the soil under the slab and an open sump pit. Purple Mountain Radon installed a perimeter drain depressurization system, utilizing the existing perforated pipe drain tile and sealing the sump pit with an airtight lid. Despite the tight space between a window well and a planter box, the team was able to dig and install the system efficiently. This proactive approach reduces the radon risk, giving the homeowner peace of mind.
