Before & After Photos

Before and after photos of crawlspace encapsulation.

In Colorado Springs, CO, this homeowner discovered elevated radon levels in a home with an unfinished basement and sump pit, prompting the need for a reliable mitigation solution to protect their indoor air quality. They chose Purple Mountain Radon for their experience, clear communication, and ability to handle custom challenges with precision. Before mitigation, radon gas was entering through the basement and sump system, creating a potential health concern. The team installed a strategically placed suction point near the sump pit, tapped into the sump lid to enhance airflow through the perimeter drain, and carefully routed the riser up the basement wall. A unique challenge arose with built-in shelving along the wall, which Purple Mountain Radon skillfully drilled through and reassembled to seamlessly extend the system into the attic and out through the roof. After installation, the home achieved safer radon levels and improved peace of mind. If you’re facing elevated radon or a challenging layout, schedule a professional radon test and mitigation to safeguard your home and family.

A sub-slab mitigation system was installed in this Colorado Springs home against back wall of basement behind HVA system. 

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.
