  • Customization – As an experienced deck contractor, we’re capable of designing a deck that meets your functional needs while complementing the external appearance of your home.

  • "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"
