Side Sewer Repair in Burien, WA
In Burien, property owners are responsible for the entire side sewer pipe connecting their home foundation to the municipal sewer main in the street. Washington Plumbing – Burien delivers trenchless pipe bursting, spot excavation repairs, and complete side sewer replacements across King County.
Common Side Sewer Problems in Burien Properties
Burien's housing boom between 1940 and 1970 utilized underground sewer pipes made of vitrified clay tile, unreinforced concrete, or bituminous fiber (Orangeburg). These materials have now exceeded their functional life expectancy.
Tree Root Intrusion into Joints
Clay and concrete pipes were installed in short sections joined by mortar or tar. Over time, ground movement cracks these joints, allowing tree roots from native firs and maples to enter seeking water.
As root masses expand, they trap toilet paper and solid waste, causing recurrent backups and eventually shattering the pipe walls.
Pipe Bellies & Offset Joints
Burien's wet winter soils and steep hillside terrain near Seahurst and Three Tree Point cause localized soil settling. This shifts pipe segments, creating offsets where waste catches.
Depressions in the line—known as "bellies"—hold standing water and sludge continuously, choking off gravity flow and triggering backups.
Cracked & Collapsed Pipe Walls
Ground pressure, vehicle traffic across driveways, and decades of wastewater erosion eventually cause brittle clay and concrete pipe walls to collapse inward.
When a side sewer collapses, wastewater cannot drain and soil falls into the line. We diagnose the exact collapse location using a sewer camera inspection.

Trenchless Pipe Bursting vs. Open-Trench Excavation
We utilize advanced trenchless pipe replacement technologies that save your mature landscaping, asphalt driveways, and concrete patios while installing modern seamless piping.
Trenchless Pipe Bursting Technology
Trenchless pipe bursting requires only two small access pits—one near your home foundation and one at the property line connection. A heavy steel bursting head attached to seamless High-Density Polyethylene (HDPE) pipe is pulled directly through the old failing clay line.
The conical bursting head fractures the brittle old pipe outward into surrounding soil while seamlessly pulling the new fused HDPE line into place behind it.
- Seamless, joint-free HDPE pipe completely impenetrable by tree roots
- Eliminates massive landscape trenches across yards and gardens
- Engineered for a 100-year subterranean service lifespan
- Full permitting and inspection coordination with City of Burien
Open-Trench Spot Excavation & Relining
When a side sewer has severe negative slope (back-pitch), severe directional bends, or when damage is confined to a single isolated joint near the surface, targeted open-trench repair is the most practical solution.
We excavate the damaged segment, install heavy-duty schedule 40 PVC pipe with mission couplings, and install code-compliant two-way cleanouts for future sewer maintenance and hydro jetting.
