At Keystone Custom Decks, we stand behind the work we do. All of our custom designed vinyl and composite decks are covered by our limited lifetime warranty. “If the structure of the deck is ever compromised due to our workmanship, Keystone Custom Decks, at our discretion, will repair the deck free of charge.” This warranty is between Keystone Custom Decks and the original purchaser and covers the labor portion of the project. Our warranty does not cover any materials that are used on your project. The warranty on materials varies by manufacturer (see specific manufacturer’s warranty for info). Our warranty does not cover the following: Using the deck in a way it was not designed for, any damage due to weather, damages that result from the owner’s neglect, etc. At Keystone Custom Decks, we take great pride in our workmanship, and we will stand behind our product. It’s our promise to you.
