FAQ

Common questions

Are the plumbers licensed?

We connect you with independent licensed, insured plumbers. California requires a CSLB license (C-36) for plumbing jobs of $500 or more — and we recommend verifying any license at cslb.ca.gov before work begins; see our guide.

Is the estimate really free?

Yes — calling costs nothing and the on-site estimate carries no obligation. You decide after you have a price.

What causes slab leaks in Ontario?

In hot-dry zone 3B, soils expand and contract sharply between dry summers and wet winters, stressing copper lines under slab foundations. Signs include warm spots on floors, unexplained water bills, or the sound of running water when everything is off.
