Water Where It Shouldn't Be? Call Now.

Burst pipes, sewer backups and dead water heaters get worse by the hour. Shut the water off at the main, then call.
What is happening?
  • Burst Pipe or Active Leak

    Shut the main valve first, then call. Every minute of running water is more to dry out.
  • Sewer Backup

    Wastewater coming back up a drain or toilet means a main-line clog. Stop running water in the house, then call.
  • No Hot Water

    Check the breaker or the pilot light first. If neither is the answer, call with the heater's age and type.

Don't know where your water shutoff is?

When a pipe bursts, the first minute matters. Here are the three shutoffs every homeowner should be able to find in the dark.
Schedule a Shutoff Walk-Through
Know Your Shutoffs 0 / 3
  1. Main Water Shutoff
    Usually at the meter near the street, or where the main line enters the home. One quarter-turn stops all water.
  2. Water Heater Shutoff
    A cold-water valve on top of the tank (or a flexible line into the tankless unit). Closes off heater supply without killing the rest of the home.
  3. Sink and Fixture Stops
    Small angle valves under each sink, behind each toilet, and behind the washer. Lets you isolate one fixture without losing whole-home water.

Septic System

Tank, Drain Field, and Lines

Septic-line clearing, riser installs, drain-field troubleshooting, and routine pump-out coordination with licensed septic haulers.

From Homeowners With Hot Water Again

Real reviews from Seattle homeowners we've helped with water heaters, drains, and leaks.

★★★★★
“Our water heater died on a Sunday and Cascade had a new tankless unit in by that afternoon. Quoted the price up front and stuck to it exactly.”

Megan R.

★★★★★
“Kitchen drain had been backing up for weeks. They hydro-jetted it, showed me the grease buildup on camera, and it has drained perfectly since.”

Tyler B.

★★★★★
“Found a slow leak under the bathroom sink I didn't even know was there. Friendly, clean, and left the cabinet drier than they found it.”
