What we do / 01
Diagnose first.
Dig (only if needed) second.
Scoping the pipe before we touch it is how we avoid replacing 60 feet of line when the problem is at 12 feet.
Camera inspection
HD color camera with locator. We show you the footage, save it for you, and pinpoint exactly where the issue is.
- Pre-purchase home inspections
- Insurance documentation
- Locate & mark for excavation
Hydro jetting
For grease, scale, and root mats — high-pressure water that scours the pipe wall back to clean.
- Up to 4000 PSI
- Restaurant & residential lines
- Far better than chemical drain cleaners
Sewer line repair
Spot repairs for cracks, bellies, offset joints, and root intrusion. Permits and locates handled.
- Excavation & spot fixes
- Cleanout installation
- Backfill & surface restoration
Trenchless replacement
Pipe lining (CIPP) and pipe bursting let us replace a sewer line with minimal digging — a game-changer under driveways and landscaping.
- Cured-in-place lining
- Pipe bursting full replacement
- 50-year material warranties
Recurring backups
If the same drain clogs every few months, the problem isn't the clog — it's the slope, venting, or root intrusion. We find the root cause.
- Slope & vent diagnosis
- Permanent fixes, not just clears
- Annual maintenance plans
How we work / 02
The honest sewer-line
process, in four steps.
No "you need to replace everything" without proof.
Scope before we quote
We push a camera through the line and you watch the screen with us. No diagnosis without footage you can see.
Locate, don't guess
We mark exactly where the issue is — depth and footage from the cleanout. That's how we avoid digging the wrong spot.
Fix the smallest thing that works
If a 6-foot spot repair solves it, we don't replace 60 feet. Trenchless lining only when it's actually warranted.
Re-scope after
Post-repair camera pass to confirm the line is sound and clear. Footage saved for your records.
FAQ / 03
Drain & sewer questions.
Got something not covered? Call (360) 488-8553.
How much does sewer scoping cost?
It varies, but we price it transparently up front. If we end up doing the repair, the scoping fee is typically credited toward the work.
What is trenchless and is it right for me?
Trenchless replaces or relines a sewer line with one or two small access pits instead of trenching the whole length. It's great under driveways, mature landscaping, and porches — but it requires a serviceable host pipe and good access. We'll tell you honestly if it fits.
Will hydro jetting damage my pipes?
Not when sized right for the line. We adjust pressure and nozzle to the pipe material and condition — and if the line is already fragile, we recommend a different approach.
Why does my drain keep clogging?
Repeat clogs usually mean a slope problem, a venting issue, or root intrusion in the main. A scope tells us in 15 minutes which one it is.
Do you handle restaurant grease lines?
Yes — we hydro jet kitchen lines and grease traps for light commercial customers in Snohomish County.
