If something bothers you, don't be afraid to cancel the contract. Sending the cancellation to the contractor by registered mail will give you a record of its mailing date and of its receipt by the contractor. Thereafter, you can work out the problem with your contractor and sign a new contract, or you can get a different contractor if you prefer. If you have any concerns, see an attorney right away. Make sure all the contract terms are in writing and that you understand and agree to everything in the contract.
Warranties Be sure to get any warranty offered by the contractor for labor and materials in writing.
It should specify which parts of the work are covered and the duration of the warranty. You should also request any written warranties offered by the manufacturers of materials or appliances installed by the contractor. For patent or readily observable defects, California law limits the period within which a complaint may be filed against a contractor to four years from the date when the act or omission occurred. This statute of limitations may be extended if there is an express, written warranty issued by the contractor. If such a warranty has been breached by the contractor, the CSLB has authority to act on a complaint during the entire duration of the warranty.
