What we design, build & maintain

What we do

From a 3D design to the last paver — built in-house.

Theiss Landscape Works is a full-service design-build outfit. We render your yard before we touch it, then our own crew installs the hardscape, plantings, irrigation, and lighting. One team, one standard, from the first sketch to the final walk-through.

Landscape Design & 3D Rendering

See your finished yard before a shovel hits the dirt. We design to your property, your budget, and the Texas climate — then render it in 3D so there are no surprises.

02 — WHY US

The owner who quotes your job is on site the day it's built.

A lot of landscape companies hand your project to a sub-crew and disappear. Theiss doesn't work that way. Monty Theiss writes the plan, his own crew installs it, and he's on the job most days making sure it's done to perfection — the same way the family has done it for 40+ years.

01
Honest Agreement Guarantee
Transparent scope, transparent pricing, no surprise change-orders. You get a stress-free project and a result that lasts.
02
Owner on the job site
Monty is on site most days checking the work. The standard never drops between the estimate and the final walk-through.
03
Real warranties in writing
Two years on hardscapes and structures, 90 days on plants and irrigation. We stand behind what we build.
04
Design-build, in-house
From 3D rendering to the final paver, it's one team. No design that can't be built, no crew that didn't see the plan.
