The Best Gunite Companies in Houston: An Honest Comparison

If you search for the best gunite company in Houston, you will find plenty of pool builders and almost nothing about the crews who actually shoot the concrete. That is a problem, because the gunite shell is the one part of a pool you cannot redo, and in Houston most shells are shot by a small group of specialist contractors, not by the builder whose sign is in the yard.

Full disclosure before anything else: South Coast Gunite is our company, and it is on this list. We wrote this guide because nobody else has, and we kept it honest. Every fact about the other companies below comes from their own websites or public records like the Better Business Bureau, and each one gets a fair account of what they are genuinely good at. Houston is a big market. There is real work for all of us, and the right crew depends on your job.

First, know what you are hiring

A gunite company is not the same thing as a pool builder. The builder designs the pool, pulls the project together, and manages the trades. The gunite contractor is the specialist who shoots the structural shell: the floor, the walls, the raised spa, the bond beam. Some gunite companies work only for builders, some work directly with homeowners on repairs and structural work, and a few do both. Matching that to your situation is most of the decision.

The comparison at a glance

South Coast Gunite

That is us, so judge this entry with that in mind. We are a family-owned gunite and shotcrete contractor with more than 20 years on the Texas Gulf Coast, and we do one thing: structural concrete shells. Custom pools and raised spas, rock and waterfall structures, commercial and structural shotcrete, engineered retaining walls, and structural repairs on existing shells. We shoot for pool builders who need a crew they do not have to babysit, and we work directly with homeowners on repairs, renovations, and owner-managed builds. Our service area runs from Katy and The Woodlands east to Beaumont and south to Galveston. What you get with us that the bigger operations cannot offer is simple: you deal directly with the family that does the work, on every job.

Modern Method Gunite

Modern Method Gunite, or MMG, is the biggest operation on this list. Their site describes more than 40 years in business, operations in Houston, Austin, and Tucson, and thousands of projects a year, and they run one of the largest fleets in the Texas gunite trade. They are a dedicated subcontractor rather than a consumer-facing builder, and unlike most gunite crews they also handle interior finishes, describing themselves as a major authorized PebbleTec applicator, plus faux rock work through their Boulder Creations line. If you are a builder moving serious volume and want gunite and plaster coordinated under one roof, MMG is built for exactly that. The trade-off of that scale is the same as with any large operation: you are one of a great many jobs on the board that week.

JR Pool Plastering & Texas Gunite

JR has been in business since 1984 and holds the strongest third-party credential of anyone here: a BBB A+ rating with continuous accreditation since 1997. They run two distinct operations. For pool builders, they are a multi-trade subcontractor covering excavation, steel, gunite, tile, coping, and plaster. For homeowners, they are a remodeling company handling replastering, retiling, decking, and equipment. If you own an aging pool and want one established company to take the remodel end to end, JR is the obvious first call. For a new custom shell, they are one of several capable options, and their multi-trade model means gunite is one of many things they do rather than the only thing.

Houston Gunite, Inc.

Houston Gunite is a family-owned company established in 1984, and they present as a full-process gunite construction outfit: excavation, steel, dry-gun gunite, plaster, and custom water features like grottos and slides. They highlight commercial capability, including a rooftop pool project in downtown Houston, and a fleet they describe as able to travel anywhere in Texas. For design-heavy or commercial gunite construction where one company handles the structure start to finish, they have four decades of history. Whether they shoot shells for outside builders is not something they advertise, so builders looking for a pure sub should ask.

United Gunite Texas

United Gunite is a Cypress-based crew that works exclusively for pool builders and contractors. They do not sell to homeowners and they do not do plaster or remodeling; the pitch is focused gunite and shotcrete application, and they pair it with a mobile app that gives builders real-time material quantities and invoicing, which is genuinely unusual in this trade. They cover the Houston metro with a footprint strongest in the northwest corridor: Cypress, Tomball, The Woodlands, Katy, Magnolia, Conroe. A newer presence than the 40-year names on this list, and a fit for builders who value tight job-level reporting.

Union Gunite

Union Gunite operates out of Missouri City and supplies and installs gunite for swimming pools and retaining walls, from residential jobs up to larger commercial work, serving builders rather than homeowners. They are a newer entrant with a modest public footprint, which makes them harder to evaluate from the outside. Builders working the Sugar Land and Missouri City side of the metro may find the proximity useful; ask for recent builder references, as you should with any crew.

How to actually choose

Names matter less than fit. Whoever you talk to, the questions that separate a good shell from a future problem are the same everywhere.

• Homeowner building a new custom pool: your builder likely picks the gunite sub. Ask who it is, then ask that crew the questions below.
• Homeowner with a cracked, leaking, or aging shell: you want a contractor who works direct on structural repair, not just remodel cosmetics.
• Pool builder: decide whether you want a pure shell specialist or a multi-trade sub, then vet for the shell itself.
• Ask every crew: Do you shoot the shell in one continuous pour? How do you handle rebound? What is your curing procedure in Houston heat? Who is the nozzleman, and how long has he been on the gun?

Any contractor on this list can point to real work. The ones worth hiring will answer those four questions without flinching, because continuous pours, cleared rebound, correct steel coverage, and real curing are what decide whether a shell lasts five decades or fails in five years. That is true no matter whose name is on the truck, including ours.
