Before You Call

Water Line Repair: Common Questions

Repair or replace the whole supply line?

One leak in copper or newer PEX: repair. Multiple leaks in old galvanized or polybutylene: replacement is usually cheaper than the third repair. Trenchless pull-through replacement often avoids destroying the yard.

Who owns the water line?

You own everything on your side of the meter. The utility owns the meter and everything before it.

How do I check a company's license?

Ask for their Washington L&I contractor number and verify it at secure.lni.wa.gov/verify — active license, bond, and insurance. Listings above with a green badge are ones we've already matched to an active license in state records.
