Before anyone comes out

  • Asked for the contractor's CSLB license number
  • Looked it up at cslb.ca.gov and confirmed it is active
  • Confirmed the business name on the license matches who I am dealing with
  • Confirmed they work in my part of Anaheim Hills
  • Asked what the leak detection visit includes and costs

At the detection visit

  • They repeated the meter test and isolated hot and cold sides
  • They ruled out toilets, irrigation and the yard line
  • They explained how confident they are in the leak location
  • They described spot repair, reroute and repipe options for my house
  • I know whether employees or subcontractors will do the repair

Before signing

  • Written scope names the exact repair and the line involved
  • Openings in floor, walls or ceilings are described
  • Patching level is stated: rough close or finished
  • Permit responsibility is stated, and I checked the requirement with the city
  • Testing of the repair before closing up is described
  • Price and payment terms are in writing
  • Any warranty is written in the contractor's own terms

When the work is done

  • I watched or was shown the pressure test of the repaired line
  • My own meter test with everything off shows no movement
  • I have the removed pipe section, if I asked for it
  • I have the permit and inspection sign-off, if one was required
  • I have the final invoice matching the written scope

If a box stays unticked

  • IfThe license lookup does not match or is not activeThenDo not hire on that license; ask why, and choose another contractor if the answer is unclear.
  • IfThe leak was not isolated to hot or coldThenAsk for that testing before agreeing to a repair.
  • IfPatching or permits are left vagueThenAsk for them in writing before signing, not after the floor is open.
  • IfYour own meter test still moves after the repairThenCall the contractor back promptly; there may be a second leak or another source.

Keep a file

Put the license lookup printout, written scope, invoice, photos and permit papers in one folder. If another leak appears years from now, the next plumber will want to know what was done, where, and with what pipe. If you sell the house, buyers may ask the same.

Common questions

Do I need the CSLB lookup?

It takes a few minutes and confirms the license is active and matches the business. It is one of the simplest protections you have.

What if the plumber will not put the scope in writing?

Treat that as a reason to look elsewhere. Slab leak work is hidden once finished; the written scope is your record.

Should I use this checklist with you too?

Yes. This is a preview site for Anaheim Hills Slab Leak Repair, and we would expect you to hold us to the same checklist as any contractor you consider, starting with the CSLB license lookup.
