Round Rock built out fast, and most of its backyards came with the same thing: a concrete slab the width of a back door and a lot of flat St. Augustine behind it. A deck is how you turn that into somewhere you actually sit. Deck building is a large share of what we do in Williamson County, and Round Rock lots have their own quirks worth knowing about.
Decks we build in Round Rock
- Cedar decks. Western Red Cedar handles our heat, takes stain beautifully, and stays cooler underfoot than composite in August. Roughly $50 to $75 per square foot installed.
- Pressure-treated pine decks. The value build. Same framing standards, same hardware, lower material cost. Roughly $30 to $45 per square foot installed.
- Composite and PVC decks. If you never want to stain again. Roughly $60 to $100 per square foot installed.
- Low-profile and ground-level decks. The right answer on Round Rock's flatter lots, where a raised deck would sit awkwardly against the slab and leave an odd gap underneath.
- Covered decks and patio covers. Framed as one structure so the posts carry the roof properly instead of being bolted on afterwards.
- Deck tear-out and replacement. A lot of Round Rock's builder decks are now twenty years old and failing at the ledger and posts, not at the boards you can see.

What's different about building a deck in Round Rock
The lots are flat, which changes the design
Round Rock does not fall away the way Cedar Park and the Hill Country do. That is mostly good news, because you are not paying for tall posts and engineered footings. It does mean a standard raised deck often looks wrong: it sits eighteen inches proud of a flat yard with a dark gap under it that collects leaves. On these lots we usually build low-profile, stepping down to grade, which reads as part of the yard instead of a platform dropped into it.
Blackland clay
Much of Round Rock sits on expansive clay that swells when it rains and shrinks when it doesn't. That movement is exactly what cracks slabs and heaves shallow footings. Footing depth is the part of the quote nobody asks about and the part that decides whether your deck is still flat in ten years.
Drainage on a flat yard
Flat is easy to build on and hard to drain. When Round Rock gets a real storm, water that used to sheet across the yard now has a deck in the way. We look at where water actually goes before setting a post, because a deck that dams the drainage path turns the yard behind it into a bog and rots the framing from underneath.
HOAs
Nearly every Round Rock subdivision built since the 90s has an active architectural committee, and several have specific rules about height, materials, and how close a structure can sit to the rear setback. We prepare and submit the full ARC packet as part of the project, and pull City of Round Rock permits when the build requires them.

My Round Rock yard is completely flat. What kind of deck works?
Usually a low-profile deck that steps down to grade rather than a raised platform. On a flat lot a standard raised deck sits proud of the yard with a dark gap underneath that collects leaves and looks like an afterthought. Built low and stepped, it reads as part of the yard. The other thing we plan for on flat lots is drainage, because a deck sitting in the path water used to take will turn the ground behind it into a bog.
