5 Year Deck Warranty

So you’re ready to start building a new deck—that’s great! When you choose a deck builder, make sure they offer a warranty and that you know your options and get it in writing before starting the project. At Diamond Decks, we offer a five year deck warranty—five times the industry standard—because we believe in building products that last!!

As a testament to our work, we are happy to provide you with references so you can get a better feel for how we work. Contact us today to learn more about our services or to set up an appointment for a free estimate for deck installation!

Deck Warranty Coverage

Our five year deck warranty covers any structural damage related to the actual construction of the deck. Which includes your deck and stairs in the event that they begin to sink, shift, or lean.

Sinking: If you notice that your deck or stairs become unleveled because either one or all foundation posts have sank, or the ledger board has dropped or separated from your house, this would be covered under your warranty.

Shifting: If you notice that your deck or stairs are not level because one or all foundation posts have shifted upward, this would be covered under your warranty.

Leaning: If you notice your deck or stairs start leaning left or right because the foundation posts are leaning in that direction, that would be covered under your warranty.

It is important to note that the original owner must own the deck in order to maintain the warranty. Meaning, if you build a deck and move out of your home the next year, the new homeowner will not inherit your warranty.

Importance of a Deck Warranty

Other deck contractors may try to sell you on how structurally sound their decks are and that they are built to last. However, if there is no guarantee that they will return free of charge in the next five years if something goes wrong, how much faith can you put in a contractor?

Diamond Decks is a certified Master Deck Professional builder through the North American Deck and Railing Association (NADRA), an industry group that promotes safe, affordable, and high-quality deck building.

  • "My wife and I are very pleased with our recent experience with Diamond Decks. Our interaction with everyone from the company was great from the schedulers on the phone to the men who did the work. William remained in close communication with us until the job was completed and we were satisfied. The deck itself is beautiful and of excellent quality. We will be recommending Diamond Decks to everyone we know. -Kev Mitchell, Piney Orchard, MD"
