Family-owned since the 1980s

Four decades of Texas landscapes — and the family name still on the truck.

Theiss Landscape Works has designed and built landscapes across Cypress and Northwest Houston for over 40 years. We're still family-owned, still in-house, and Monty Theiss is still on the job site most days.

Monty Theiss · Owner
Our story

Built around one idea: do it honestly, and do it once.

Owner Monty Theiss grew up in the construction and landscaping trades around his hometown of Hockley, Texas — and he's spent more than 40 years building outdoor spaces across Northwest Houston. To this day, you'll find him on the job site checking in on his crew, making sure every project runs smoothly and efficiently for the client.

That hands-on standard is why Monty built the Honest Agreement Guarantee into every job. Clients deserve transparent, stress-free, long-lasting landscaping — no vague scopes, no surprise change-orders, no disappearing after the deposit. The family name on the truck means it gets done right.

How we work

From first call to final walk-through.

A simple, honest process — the same on a small front-yard refresh or a full backyard build.

01
Consultation
We walk your property, listen to how you want to use it, and talk budget — no pressure, no charge.
02
3D Design
We render the finished yard in photo-real 3D and put an honest, itemized proposal in writing.
03
Build
Our in-house crew installs it — hardscape, planting, water, light — with Monty checking the work.
04
Stand Behind It
Final walk-through, warranty in writing, and a maintenance plan if you want it kept showroom-fresh.

Work with the family that's done this for 40 years.
