Clay lateral failure in older Beardslee homes
Why it happens here
Homes built before the 1990s often have clay sewer laterals. Root intrusion and ground movement crack them, and once cracked, waste backs into basements and floor drains instead of draining away. The Sammamish River corridor has some of the oldest stock in the area.
Our approach
We extract and disinfect first, then camera-check the affected area with you so the source is documented for insurance. We dry the space fully and hand the lateral repair to a licensed plumber before closing out.
