Specializing in emergency water damage mitigation, mold remediation, moisture control, Radon mitigation systems and air duct cleaning for residential, commercial and industrial customers.

"AdvantaClean installed a radon mitigation system at my house. Within two years, the piping they put in on the outside of the house to vent the gas collapsed. Upon further inspection, the ~30ft., ~50lb. pipe had been affixed upright by two plastic ties screwed to the siding, and the weight of the pipe had caused the screws to tear through the thin plastic on both ties. Similar systems I've looked at in the neighborhood use lighter, metal, gutter-like pipes, and metal ties (stronger ties for lighter pipes!). When contacted, Dave (the owner) tried to get me to pay $300 to fix it, claiming that he otherwise "couldn't help me" because I couldn't reasonably expect their work to last for almost two years. He also said any kind of warranty was void because "wind damage" wasn't covered. The winds in Frederick topped out at 8mph the day it fell, but I guess he's right. It honestly WOULD be unreasonable to expect this quality of work to hold up to normal weather events (normal storms and winds in a fairly mild weather part of the country) and wear for two whole years! I'm frankly surprised it didn't fall earlier. Oh, and it took me calling AdvantaClean three times to get ahold of him (thought I was promised a call back each time!), but that's way less egregious than the whole "doing sub-par work and trying to get me to pay for it when it failed" thing."

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed.
