Why Epoxy Floor Quotes Vary So Much (and What You're Actually Paying For)
If you've collected a few quotes for an epoxy garage floor in San Antonio or the Hill Country, you've probably noticed something: the numbers are all over the place. One company might quote half of what another does for the same two-car garage. It's a fair question to ask why.
The honest answer is that two quotes can say "epoxy floor" and describe completely different products. Some of those differences are visible on day one. Most of them show up in year two, three, or five. Here's what actually drives the price of a coated floor, so you can compare quotes on what matters.
1. Surface prep is most of the job
A coating is only as good as its bond to the concrete underneath. The most common reason floors peel, bubble, or flake is prep that was rushed or skipped.
Proper prep means mechanically grinding the slab with diamond tooling to open up the surface, repairing cracks and spalls, and removing old sealers and contaminants. It takes heavy equipment, dust control, and time. Lower-cost installs often replace grinding with an acid wash or a light scuff, which is faster and cheaper but gives the coating far less to grab onto.
What to ask: "How will you prepare my slab, and what equipment do you use?"
2. Moisture is a South Texas reality
Concrete is porous, and moisture moving up through a slab is one of the biggest threats to a coating. In our climate, a moisture vapor barrier (MVB) primer is cheap insurance against bubbling and delamination later. It's also an easy step to leave out of a lower bid.
What to ask: "Does your system include a moisture barrier primer?"
3. Not all coatings are the same material
"Epoxy" covers a wide range of products, from big-box roll-on kits to professional-grade systems. A quality floor is usually a multi-layer system: a primer or base coat, a full broadcast of decorative flake, a grout coat to lock the flake in and even out the texture, and a durable UV-stable topcoat.
Each layer adds material and labor, and each one does a job. Skipping the grout coat or thinning out the topcoat saves money up front but shows up later as uneven flake, rough spots, or a finish that yellows and wears through in the tire paths.
What to ask: "How many coats are in your system, what product is the topcoat, and is the flake a full broadcast?"
4. Insurance and who's actually on the job
A low price means less if nobody is around to stand behind the work. Proper liability insurance and a business you can reach after the check clears are part of what you're paying for.
What to ask: "Can I see your certificate of insurance, and who will be on site doing the work?"
5. A word about "lifetime" warranties
You'll see "lifetime warranty" in a lot of flooring ads. It sounds like the safest choice, and some of those warranties are solid. But the word "lifetime" can mean very different things, so it's worth reading closely before it becomes the reason you pick a contractor.
A few things to check on any warranty, lifetime or not:
Whose lifetime? The product's, the company's, or only as long as you own the home? Is it transferable if you sell?
Who backs it? A manufacturer's material warranty usually covers product defects, not installation. If the floor fails because of prep, it may not apply.
What's excluded? Look for exclusions like moisture or vapor issues, hot-tire pickup, concrete cracking, UV yellowing, and normal wear. Those are some of the most common real-world problems.
What keeps it valid? Some warranties are prorated or require paid recoats or inspections on a schedule to stay in effect.
And the simplest point of all: a warranty is only as good as the company that's still in business to honor it.
What to ask: "Can I see the warranty in writing before I sign? What does it exclude, and who honors it?"
Why we offer 5 years instead of "lifetime"
AES offers a 5-year written warranty on residential floors, and we chose that number on purpose. We're a small, owner-operated company, and we'd rather make a promise we know we'll personally be here to keep than one that just sounds good in an ad.
That doesn't mean we expect your floor to last five years. We build every floor to last well beyond its warranty, with the prep and materials described above. The warranty is our guarantee on the work; the system is what keeps you from ever needing it.
Think in cost per year, not cost per square foot
A floor isn't a one-time purchase; it's something you live with every day. A cheaper floor that needs to be ground off and redone in a few years usually costs more than doing it right once, and removing a failed coating adds cost to the second job.
When you compare quotes, divide each price by how long you can realistically expect the floor to last and what the warranty actually covers. That number tells you much more than the price on the first page.
Where AES fits
We're not the cheapest option in San Antonio, and we're comfortable with that. We'd rather explain our price once than apologize for a failed floor later. Here's what's included in every AES floor:
Mechanical diamond-grind prep with crack and spall repair, not an acid wash.
Professional-grade, multi-coat systems built for Texas heat and moisture.
A straightforward 5-year residential warranty in writing, with no fine-print games.
Fully insured to general contractor standards, BBB accredited with an A+ rating, and Sherwin-Williams trained.
Owned and run by three Army veterans who answer the phone and stand behind the work.
Whoever you hire, we encourage you to ask every contractor the questions above. A good installer will be glad to answer them.
