─── Common Questions
Before you
break ground
The questions we get asked most on the first call. If yours is not here, pick up the phone and ask it.
In Washington State, property owners are generally responsible for maintaining, repairing, and replacing the entire side sewer pipe connecting their house or commercial building to the municipal main sewer, including any portion running beneath the public right-of-way.
Common warning signs include persistent drain backups, slow-draining sinks or toilets, sewage odors in the yard, wet or unusually lush green patches of grass, standing water near the foundation, and gurgling noises in your plumbing fixtures.
Tree root intrusion is the leading cause of pipe damage in the Pacific Northwest. Age-related pipe deterioration (such as old concrete, orangeburg, or cast iron), ground shifting, soil settling, and heavy vehicle pressure over shallow lines can also cause cracks and structural collapses.
We conduct a sewer scope video inspection by inserting a high-resolution camera directly into the pipe. This allows us to pinpoint exact depth, location, and structural issues like cracks or root blockages without unneeded digging.
Yes. Most cities and counties across Skagit, Snohomish, and Whatcom County require specific utility, plumbing, or right-of-way excavation permits. We handle local permitting coordination and line up required municipal inspections to guarantee full code compliance.
A side sewer carries wastewater from indoor plumbing fixtures (sinks, toilets, showers) to the municipal sanitary sewer or septic system. A storm drain carries rain and surface runoff away from foundations and driveways into catch basins or storm retention systems.
Most standard residential side sewer or storm drain replacements are completed in 1 to 3 days. Timeline factors depend on pipe depth, distance to the main connection, soil conditions, and required city utility inspections.
