The lead story

A Deck That Fits This Town

San Marcos is not a suburb copy of Austin. It is a river town with a lot of rental houses, steep and low lots side by side and fast changes in the ground. A deck that works here has to fit all of that.

For an owner who lives in the house, that means a deck sized for how you use the yard. Shade where the afternoon sun hits. Stairs that feel solid. Boards you can live with for years.

For an owner who rents the house out, it means a deck that holds up to heavy use, with rails and stairs that do not turn into a tenant call. We build and fix for both, and we tell you plainly which path fits your deck. Start with new decks or deck repair.

Most Decks Here Belong to Someone Who Lives Elsewhere

Census numbers show only 30.8 percent of homes in San Marcos are lived in by their owner. So most decks in town are used by tenants and paid for by landlords who are not on site.

We work that way. We meet your manager or tenant at the house, take photos, and email you a written scope and price. Between leases is the easiest time for bigger work. Read more on rental property decks.

Under the boards

Stairs, Railings and the Ground That Moves

Most deck trouble starts in two places. The first is the stairs and rails, because they take the most wear. The second is the ground, because our soil can dry out and crack, then swell when the rain comes back.

Over years, that movement can push a footing out of line. A post leans. A stair stringer twists. A rail starts to give. New boards on top will not fix any of it.

So on every repair, we look under the deck first. On every new deck, we plan the footings for the ground we have. See stairs and railings for what we check.

River and hills

From the River Bottom to the Hill Country Edge

A covered porch is a deck with a roof and a view of the street.

The west side of town climbs into the Hill Country. Lots there slope, so decks need taller posts, more bracing and real stairs down to the yard. Near the river, lots sit lower, and flood zones come into play.

Outside city limits, Hays County requires a permit for any kind of development. Parts of the county also sit over the Edwards Aquifer, where state rules apply to building at private homes. Our permit guide covers both.

On any lot, shade makes a deck worth using. Look at covers and pergolas or a covered porch if your deck sits empty all afternoon.

Questions People Ask

Do I need a permit for a deck in San Marcos?

The city lists decks under its building permits. It does not post a size or height that sets the line. Ask the city with its Permit Requirement Determination Form, or email permitinfo@sanmarcostx.gov. Our permit guide walks through it.

Do you work on rental houses and duplexes?

Yes. Most homes in town are rented, so a lot of our work is for owners and managers. We can meet you or your manager at the property and send photos with the estimate.

Can you fix my deck instead of tearing it out?

Often, yes. If the posts and beams are sound, new boards, stairs or rails can be enough. If the frame is soft, a rebuild is the safer call. We show you what we find.

What does a free estimate include?

A visit to the site, a look at the frame and footings, and a written scope with a price. There is no charge for it and no pressure to sign.

Do you build outside the city limits?

Yes, across nearby Hays County. Outside the city, the county runs permits instead of the city. Some lots also sit over the Edwards Aquifer, which has its own state rules.
