Diamond Decks

Diamond Decks is a San Antonio deck builder and general contractor that designs and builds custom decks, railings, concrete patios, and sunrooms tailored to your space and budget. As a concrete contractor and railing contractor, they can deliver code-compliant footings, proper drainage, and durable, low-maintenance rail options like aluminum or composite—ask for samples to compare looks and grip. As a sunroom contractor, they can enclose your patio with insulated glass and HVAC-ready framing; request a 3D design, clear timeline, and written scope with permit handling included. For the best value, ask for line-item pricing, material options (cedar vs composite), warranty coverage, and a maintenance plan before you commit.
