New lines and repairs, dug to depth and set to hold.
New home going in? Old sewerline failing? Adding a bathroom or ADU? Sewerline work is one of those jobs where you really want the same team doing the excavation and the pipe work. Coordination problems between separate trades are where most homeowners get stuck, and it usually ends up costing more.
We're licensed for both. We hold Oregon plumbing contractor certification (PB #PB2389) and handle the full scope: excavation, pipe install, connection, backfill, and site restoration. One team, one point of contact, one estimate.
We work directly with local municipalities and utility providers to keep permits and inspections on track. If something needs coordination, we handle it.
Sewerlines need consistent slope to drain properly. We use laser levels and grade rods to hit spec every time. Cutting corners here causes backups years down the road.
We use approved pipe materials rated for the load and lifespan you need. No cheap patch jobs, no shortcuts that fail after a few winters.
Before we dig, we identify existing utilities, call in locates, and plan the work to avoid surprises. It's tedious, but it prevents the very expensive kind of mistakes.
We use the right fill material and compact it correctly. That prevents settling, sinking spots, and future problems above your line.
When we're done, your yard looks like it did before we started, not a torn-up mess. We regrade, seed, and clean up as part of the job.
