ALS Property Associates, Inc Before & After Photos

ALS Property Associates installed an energy recovery ventilator at a residential property in Jonesville, MI. The ERV was installed to help with the high radon levels. There was multiple crawlspaces that could not be properly sealed and a regular radon mitigation system would to be feasible. The ERV will bring in fresh air and create a small positive pressure inside the home to help reduce radon levels.

The radon removal system was installed with a sub-slab depressurization that was run from the basement to the garage. From the garage the schedule 40 piping was run to the attic where the radon fan was installed and vented through the roof.
