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Older homes in neighborhoods like Queen Anne, Rainier Valley, and North Seattle often contain galvanized steel or outdated copper pipes that are prone to corrosion, scaling, and leaks.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:

  • Full system replacements with durable PEX or Type L copper
  • Water quality and flow improvements
  • Long-term material warranties
  • Clean, efficient workmanship with minimal wall and floor disruption

We’ve upgraded full systems in homes from Edmonds to Issaquah — bringing them up to modern standards.

Main Shutoff Valve Replacement

Your main shutoff valve is the most important control point for your home’s water system—and often the most overlooked. If it’s stuck, leaking, or simply old, we can replace it with a modern, code-compliant valve for easy, reliable control in case of an emergency.

We recommend this upgrade for homes in areas with older infrastructure, such as Snohomish, Newcastle, and Kenmore.

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

Gas Line Installations & Repairs

We also install and repair gas lines for indoor and outdoor appliances. Whether you’re installing a new gas stove in Lynnwood or adding an outdoor BBQ line in Mukilteo, our licensed technicians will make sure everything is safe, tested, and up to code.

Frequently Asked Questions


How do I know if I need a water line replacement?

If you’re seeing discolored water, low pressure, or soggy spots in your yard, it could be a sign of water line failure. We offer inspections throughout Seattle, Redmond, and Bothell.

Is repiping with PEX better than copper?

Both materials are excellent. PEX is flexible, more affordable, and ideal for retrofits in older homes, especially in Capitol Hill or Fremont. Copper is highly durable and better for high-heat applications.

What’s the benefit of trenchless repair?

Trenchless relining is ideal if you want to avoid digging up your yard or driveway. It’s faster, cleaner, and available to customers in cities like Bellevue, Woodinville, and Sammamish.

Do you replace main shutoff valves?

Yes, and we recommend it if yours is older or difficult to operate. It’s a critical upgrade for any homeowner.

Can you handle emergency leaks?

Absolutely. We provide emergency pipe and water line services across King and Snohomish counties.
