We started with decks and we’re proud to be certified as master deck builders through the North American Deck and Railing Association (NADRA), an industry group that promotes safe, affordable, and high-quality deck building. We don’t build cheap decks because we believe in quality over quantity. And that’s why we provide a five-year warranty for our products—five times the industry standard.

"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"

"Just wanted to express our thanks to Diamond Decks for a job well done. Our deck is absolutely beautiful, and is just how we envisioned. The crew that worked on our project had an obvious attention to detail. Min is a master of his trade, and he and the other guy (sorry, didn't get his name) worked their tails off to get the project done on time. We did have a little issue where we had to have some of the existing framing replaced, which added to the cost of the deck. But that was not anyone's fault, and Buddy was very clear to begin with that once the old decking was removed there could be some issues (which there clearly was). Over all Diamond was comparable to two other bids we received, and Buddy was sensitive to keeping the cost down, but still factored superb quality materials (Fiberon) in the price. The project was started ahead of schedule, and was completed on time. All in all, my wife and I would highly recommend Diamond, if quality at a reasonable cost is the goal. (I've learned years ago, cheapest is never the best). Hats off to Diamond Decks. Sincerely, Bruce and Susan Gaesser (Ellicott City)"

"The work that Diamond Decks did on our screened in porch, far exceeded our expectations! Our porch looks amazing and we attribute that to our initial consultations with Buddy, the superior workmanship of the construction team, and the continued consultations and suggestions from Bill. Everyone who sees the porch for the first time, is amazed!"

"Diamond Decks was great! We used Diamond Decks to tear down an old deck and replace it with a new deck w/decking underneath while we were selling my mom's house. William Zinnert helped us with the proper paperwork for our HOA and pulled the permit for Howard County. They started the project when they said they would. They followed our suggestion of which side of the house to go around. The guys on the job were punctual, respectful and efficient. They did not cut any corners. They passed all inspections with Howard County. They cleaned up after the job was finished. William Zinnert was available at all times for questions. I highly recommend Diamond Decks for your next project. Katie Randolph"

"The deck was installed very quickly. The manager in charge was helpful in getting the necessary paper work and approval to build the deck.He also gave us very good recommendations on the size of the deck, and giving us options on the steps vs. a larger deck. He was very pleasant to deal with. "

"The recent service call to replace some deck planks that were discolored went effortlessly for us. I had planned to move the deck furniture and potted plants away from the affected area but they beat me to it by coming earlier than expected. They even put everything back! Couldn't be more satisfied. "
