Toilet Repair: Common Questions

My toilet keeps running — is that urgent?

It's money, not safety: a running toilet wastes up to 200 gallons a day. Try a flapper replacement first ($10 DIY); if it persists, the fill valve or flush assembly needs a pro's 30 minutes.

Repair or replace the toilet?

Repairs under ~$250 on a decent toilet: repair. Cracked porcelain, chronic clogs on an old 3.5+ gallon unit, or repeated wax-ring failures from a rocking base: a new toilet installed often costs little more.

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.
