Whole-Home Pipe Replacement & PEX Upgrades
Older homes in neighborhoods like Queen Anne, Rainier Valley, and North Seattle often contain galvanized steel or outdated copper pipes that are prone to corrosion, scaling, and leaks. Our repiping services include:

Pipe Relining
(Trenchless Repair)
When pipe replacement isn’t ideal, pipe relining offers a cost-effective, non-invasive alternative. This trenchless method reinforces the inside of your existing pipe with a durable liner — perfect for sensitive areas like Medina, Mercer Island, or yards with mature landscaping. Ideal for:
- Cracked drain or sewer lines
- Pipes under driveways, patios, or landscaping
- Minimizing digging and restoration costs
