A service and repair contract in California is an agreement between a contractor and a homeowner for work that involves repairs or services related to plumbing, electrical, heating/air conditioning systems, or any other household appliance repairs. This type of contract must include specific details about the services to be performed, exact costs for labor and materials, payment terms, as well as any guarantees or warranties provided by the contractor. It is important for homeowners to carefully review these contracts before signing to ensure they fully understand their rights and obligations.
