How do I find a good garage floor contractor in Houston?

Look for contractors who specifically mention diamond grinding (not acid etch), use UV-stable polyaspartic topcoats, provide written contracts and warranties, and have recent work in your area they can reference. Avoid contractors who give estimates without seeing the floor, or who can't explain their prep process.

Why is Houston a harder market for garage floor coatings?

Houston's heat, humidity, UV intensity, and concrete expansion/contraction patterns create conditions that expose inferior products and prep methods faster than northern climates. A coating that lasts 10 years in Minnesota may fail in 2–3 years in a Houston garage. Contractors who know the local conditions — and use polyaspartic for UV-exposed surfaces — produce results that hold up.

How to Choose a Garage Floor Contractor in Houston

Houston and Fort Bend County have dozens of garage floor coating contractors. The range of quality is enormous — from professional crews with proper equipment and chemistry to one-man operations with a box-store kit and a garden hose. Here's how to tell the difference.

Start with the Prep Method

Before you ask about price, ask how they prepare the concrete. This single question reveals more about a contractor than anything else.

Diamond grinding: Industrial machines with diamond tooling grind the surface to remove laitance, old coating, oil, and curing compounds. This creates a mechanical bond profile the coating adheres to permanently. This is the correct method.
Acid etching: Muriatic acid or similar is applied to the surface to chemically open pores. Faster, cheaper, and widely used by lower-tier contractors. It doesn't remove laitance or contamination, and it doesn't create an adequate bond profile for Texas heat conditions.
Pressure washing only: A sign the contractor doesn't understand coating adhesion. Walk away.

Understand What You're Comparing

Getting three quotes is smart. But if you're comparing a $1,200 quote to a $3,200 quote, you're not comparing the same thing. The price difference almost always reflects one or more of: prep method, product quality, film thickness, warranty, and whether your tires will be pulling up the coating in three summers.

Ask every contractor:

What coating product are you using (brand and line)?
Epoxy or polyaspartic base? Epoxy or polyaspartic topcoat?
What is the film thickness after cure?
Is the topcoat UV-stable?

The UV question matters most in Houston. Standard epoxy topcoats yellow in UV. A coating that looks great in January will be noticeably yellowed after its first Texas summer. Ask "Is your topcoat UV-stable?" and watch the response. A contractor who knows what they're doing will say yes, specify polyaspartic or polyurea, and explain why.

Red Flags to Watch For

Estimate given over the phone without seeing the floor
"We'll take a deposit and schedule" without a written scope of work
No mention of diamond grinding — only acid etch or "standard prep"
No written warranty
No insurance documentation available
Subcontracting without disclosure
Large downpayment required before any work begins

Green Flags to Look For

In-person estimate with concrete assessment before pricing
Specific mention of diamond grinding
Polyaspartic or polyurea topcoat for Texas UV conditions
Written contract with product specifications
Written warranty on labor and materials
Recent local references you can contact
Crew is the contractor's own employees

How to Compare Quotes Accurately

To compare quotes fairly, get the following in writing from each contractor: prep method, base coat product and brand, topcoat product and brand, total installed film thickness (mils), warranty terms. Once you have this from each bidder, you can compare apples to apples. A cheaper quote using acid etch and a non-UV-stable epoxy topcoat isn't cheaper if it fails in three years and you're paying to redo it.
