A radon mitigation system only protects your family while the fan is running, and radon fans wear out. Most last 8 to 12 years; some fail sooner in attics that hit 130°F every summer or on exterior walls that take a beating from York's freeze-thaw winters. The warning sign is the U-tube manometer on your pipe: when the system is working, the two liquid columns sit at different heights. When they are level, the fan has stopped and radon is entering your home again exactly as it did before the system was installed.
We replace fans on any system, regardless of who installed it. We stock the common models — RadonAway RP145, RP265 and GP series, Festa AMG Maverick and Legend, and Fantech Rn series — and match the replacement to the pressure and airflow your system actually needs rather than swapping like-for-like without thinking. If the original fan was undersized for tight York County shale ground, or oversized for a porous limestone lot, replacement is the moment to correct it. A fan swap typically takes under an hour, and we retest afterward.
Fans are not the only failure point. Over time, PVC joints can separate, exterior pipe can crack, the sump lid gasket can dry out, and condensation can pool in horizontal runs and drip back into the fan. We also see systems that were never sealed properly in the first place — open floor-wall joints, unsealed slab cracks around the suction point, sump pits with a loose plywood cover — which forces the fan to pull basement air instead of soil gas. A repair visit includes a full system inspection, smoke testing at joints and penetrations, and correction of whatever we find.
If a home inspector flagged your radon system during a sale, we can address the report items quickly: missing labels, a manometer that isn't visible, an exhaust that terminates too low or too close to a window, or an aging fan the buyer wants replaced before closing. We provide documentation the buyer's agent can file.
