Statewide conditions
Drains & sewer in Washington: what to know
Long rainy seasons saturate soil around older pipe, and roots from mature trees cause repeat clogs. Side sewer work in Seattle needs a city permit.
A camera inspection shows the problem's location and depth, and trenchless lining avoids digging on steep lots.
Spokane's large trees also root into old laterals.
- Climate
- Washington gets periodic hard freezes and ice storms, often after mild spells, which catch exposed pipes off guard. Pipes in crawl spaces, exterior walls and garages are the first to freeze.
- Typical foundations
- Older Seattle homes often have basements and aging side sewers, and the region is seismically active. Most common: basements.
Drains & sewer services
Drain cleaning
If one fixture is slow, the clog is usually in that fixture's branch line. If several drains back up at once, or the basement floor drain fills when you run the washer, the main sewer line is blocked and needs a larger cable or a jetter.
Hydro jetting
Hydro jetting cleans the full width of a drain pipe with high-pressure water, washing out grease, scale and fine roots that a cable only punches a hole through. It works best on sound pipe and is usually done after a camera inspection confirms the pipe can take it.
Sewer camera inspection
A sewer camera inspection runs a waterproof camera through the line from your house to the city main and records what it finds: roots, cracks, sags, offset joints or collapsed pipe. It's the best way to decide between cleaning, spot repair and replacement.
Sewer line repair
A damaged sewer line can be fixed with a spot repair, a trenchless liner, pipe bursting or an open-trench replacement. Which one fits depends on what the camera shows, how deep the pipe is, and what's on top of it, such as a driveway, trees or landscaping.
