Trenchless Water Line Replacement — Greater Seattle
Replace your water line without destroying your yard
Your Yard Doesn't Have to Be a Construction Zone
A failing water line used to mean one thing: a backhoe in your driveway and a trench across your lawn. Not anymore.
Done Right Plumbing specializes in trenchless water line replacement — a modern approach that gets your water flowing again with minimal digging, less mess, and faster results. We own our own directional drilling rig (no subcontractors), so we control the quality and timeline from start to finish.
Signs You Need a Water Line Replacement
Not sure if your water line is the problem? Watch for these warning signs:
- ✓Unexplained spike in your water bill — often the first sign of a hidden leak
- ✓Low water pressure throughout your home — not just one fixture, but everywhere
- ✓Discolored or rusty water — sediment or corrosion in aging pipes
- ✓Wet spots in your yard — especially along the path from the street to your home
- ✓Recurring repairs — if you’ve patched the same line multiple times, it’s time to replace
How Trenchless Replacement Works
Camera Inspection
We start by running a high-resolution camera through your existing line to pinpoint the damage and map the route.
Directional Drilling
Using our own horizontal directional drilling rig, we bore a new path underground — beneath your driveway, landscaping, and sidewalks — without digging them up.
New HDPE Pipe Installation
We pull through a new high-density polyethylene (HDPE) pipe that’s corrosion-resistant and built to last 50+ years.
Connection & Testing
We connect the new line to your home and the city main, pressure-test everything, and restore water flow — usually the same day.
Why Trenchless Beats Traditional Excavation
Minimal Yard Disruption
Your driveway, lawn, and landscaping stay intact. We only need small entry and exit points — not a trench across your property.
Lower Total Cost
Less excavation means less restoration. You’re not paying to re-pour concrete, re-sod the lawn, or replant landscaping.
Faster Completion
Most trenchless replacements are done in a single day — traditional excavation can take 3–5 days or more.
Longer-Lasting Results
HDPE pipes resist corrosion, root intrusion, and ground shifting. Your new water line will outlast the old one by decades.
