We have a minimum labor warranty of 1 year for our work only, from the date of installation. Longer labor warranties are available on larger jobs at additional charges. It does not cover parts and materials, unless we specifically express that in a written contract. Material manufacturers carry their own warranties, and you will need to consult their respective manuals. (Example: we installed a switch, but the switch turned out to be faulty due to manufacturing defects and our installation was correct; if we come back to replace the switch, we will have to charge another service call.) We will not warranty or validate someone else’s work, we warranty ONLY what we do. If our work is altered in any way, by anyone, even if it’s another electrician, our warranty is voided, and follow-up visits will be charged at our standard rates.
