Diamond Decks Expert Deck and Patio Builders

Deck, Screened Porch & Patio Construction in Columbia, Ellicott City, Annapolis, MD


If you’re looking to expand your outdoor living space with a deck, patio, or screened porch, turn to the experts at Diamond Decks. We pride ourselves on providing unparalleled customer service and the highest level of technical skills and expertise. We build decks, patios, screened-in porches, hardscapes, and even provide general contracting services.

That means we use your feedback to guide our planning process. And once the building begins, our crews maintain a clean work area, tend to your landscaping, and even power wash your new deck once they’re done.  This attention to detail has garnered us an A+ rating from the Better Business Bureau, and a certification as one of the first and only Master Deck Professionals in Maryland as designated by the North American Deck and Railing Association (NADRA).

Our Deck Building Experience

When it comes to deck design and installation in Maryland, there’s no better place to turn than Diamond Decks. We have been constructing decks, screen rooms, patios, and other home additions since 1992, and from the start we’ve priortized terrific customer service, unparalleled craftsmanship, and the use of high-quality and long-lasting materials.

We use products from trusted manufacturers such as Azek, Fiberon, TREX, and TimberTech to ensure that our customers’ decks will hold up for years to come. Like our decking materials, our durable, crack-resistant patio pavers are also designed to hold up long into the future, with almost no need for maintenance.

We can also install custom screen rooms to increase the livable space of your home and help you enjoy the outdoors in the comfort of an enclosed space. We can even add a ceiling fan, lights, and other touches needed to make your screened porch feel as inviting as any other room in your house.

Our Guarantee

Diamond Decks doesn’t build cheap decks. Our expert builders use high-quality, durable materials to build additions that will last a lifetime. Because of this difference, we’re able to offer a two-year warranty—twice the industry standard. We also offer maintenance plans to ensure your deck remains beautiful for years to come.

But don’t take our word for it. Read some of our customer testimonials to see how we’ve done for homeowners in the past. You’ll see the level of expertise and customer service that we bring to every job.
