A broken underground sewer pipe, damaged wax seal under the toilet, or dried P-trap allows raw fumes straight into living areas.

Our licensed Riverdale technicians isolate the exact breach with non-invasive smoke and high-definition video sewer cameras.

The curved pipe under every drain (the P-trap) holds standing water that blocks sewer gas. When a drain goes unused for weeks, the water barrier evaporates completely, giving sewer gases direct entry into your rooms.
Run water for 60 seconds down the affected fixture or pour a cup of water into floor drains. If the odor lingers after water refill, the seal or vent is compromised.
