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.

How fast can someone get to Altadena?

Response times depend on provider participation, location, technician availability, and demand. Emergency calls are prioritized; when you call, we tell you honestly what's available for Altadena right now.

Is hard water a problem in Altadena?

Much of inland Los Angeles County has mineral-rich water. Scale builds up in water heaters, on fixtures, and inside tankless heat exchangers. Regular flushing — and in some homes a softener or conditioner — extends equipment life.

What causes slab leaks in Altadena?

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.
