We had a radon fan installed in our crawlspace last month, and it’s made a huge difference in our peace of mind. The crew sealed the sump hole, ran a PVC pipe up through the garage, and mounted the fan outside near the roofline so it vents safely. It’s quiet and runs continuously; our test readings dropped from 8.2 pCi/L to under 0.5 pCi/L. Feels like a solid investment in home safety.
