ALS Radon & Environmental, Inc Before & After Photos

Main extraction point of a multi extraction point radon system.

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. 

This is an good example of crack sealing completed on a radon mitigation project. It is important to seal all areas of the concrete slab and/or foundation to seal off radon entry points. 

Dual suction points. One for the concrete slab and the other for the concrete addition crawlspace. 

Here is a before and after photoshoot detailing a radon extraction point installed by ALS Property Associates, Inc. in Otsego, MI. This system ended up having (3) radon extraction points.
