Built around five man-made lakes in 1967, Columbia is Howard County’s planned community, known for its tree-lined neighborhoods, the open water of Lake Kittamaqundi, and the village squares of Wilde Lake, Harper’s Choice, Long Reach, and Owen Brown. Homeowners here care as much about the view from the back porch as the curb out front.
Since 1993, Diamond Decks, a trusted deck builder in Columbia, MD, has built custom decks, screened-in and covered porches, and patios for Howard County homeowners who want their outdoor spaces to match the neighborhood.
Why Diamond Decks Stands Out in Columbia
Columbia’s clay soil, summer humidity, and shaded lots punish cheap builds, which is why choosing the right deck contractor in Columbia, MD, matters. Our team addresses regional challenges with a specialized approach:
- Owner Manages Every Job: Bill Zinnert personally manages every Columbia project, and ensures all work is consistently.
- Higher-Grade Materials: #1 grade extreme-rated .23 framing under composite from Fiberon, Trex, Timbertech, Wolf, and Deckorators.
- Two Specialized Crews: A dedicated porch crew and deck crew, with 3D interactive design up front and a 1-week average on-site build time.
- Award-Winning Reputation: Best of the Best winner since 2018, NADRA member, 2,500+ projects across Howard and Anne Arundel County.
