What a pool contractor checks here
The $25,000 contractor's bond is the legal minimum, and it is shared by everyone with a claim against this license. On a $100,000 pool it covers very little, so it is not a substitute for a good contract.
Before you sign: confirm the license is active on that day, that the business name and license number on the contract match this record exactly, and that the salesperson is either on this license or registered with CSLB as a home improvement salesperson. The full checklist.
