1. Are you licensed, bonded, insured, and carrying workers' comp?
Why it matters. Pool cleaning by itself does not need a contractor license, but any equipment or repair work over $500 needs the CSLB C-53 Swimming Pool Contractor license. Insurance protects your property if a tech slips on the deck.
Good answer. A C-53 license number read off without hesitation, plus an offer to email a certificate of insurance the same day. Verify the number on the California State License Board lookup page.
Red flag. We don't really need that or I'll get back to you on the number.
