Basement Sewer Backup — Delaware County, PA
Basement Sewer Backup in Delaware County, PA
Same-Day Emergency Response — We Clear the Backup and Find the Cause
A basement sewer backup is a sewage emergency. Effluent on your basement floor is a biohazard, a structural risk to finished spaces, and a sign that your main sewer line is completely blocked or collapsed. In Delaware County, basement backups spike during heavy rain events when groundwater infiltrates aging clay tile laterals and overwhelms the main. They also occur when root masses inside the pipe finally grow dense enough to stop flow entirely. Either way, the response is the same: clear the line, camera it, understand what caused it.

- Call us. We respond same-day, including nights and weekends, no overtime charge.
How We Clear a Basement Sewer Backup
- Emergency Hydro Jet — High-pressure water blast breaks up the blockage and flushes it through. Faster and more thorough than snaking.
- Camera Inspection — Always run after clearing. We confirm the line is open all the way to the municipal main and identify the cause: roots, grease, offset pipe, or collapse.
- Permanent Repair If Needed — If the camera shows a structural problem (cracked pipe, root entry, pipe offset), we quote the repair on the same visit. CIPP lining or pipe replacement.
Why Basements Back Up During Rain
Clay tile sewer laterals — standard in Delaware County homes built before 1970 — are not watertight. Every joint allows groundwater to infiltrate during heavy rain. When groundwater infiltration plus normal household wastewater volume exceeds the pipe’s capacity, the line backs up into the lowest point in the house: the basement floor drain. This is called inflow and infiltration (I&I). CIPP lining eliminates the joint gaps and stops the infiltration permanently.
