The warranty on an epoxy floor: 10 clauses to look for

The warranty on an epoxy floor is only as good as its exclusions, the list of things it won’t cover, and the people who stand behind it. On September 28, 2026, we looked up 87 floor coating company listings across Oklahoma, Arkansas, Mississippi, Missouri, Tennessee, and Texas. Only 20 posted real written terms. 58 showed a number, like “15-year” or “lifetime,” with no terms we could find.

Most of the exclusions in those 20 were fair. A few were not. They let the installer decide after a failure that it’s someone else’s fault. Below are the 10 clauses we’d ask about before signing. Each one comes with a plain question that turns it into something you can hold a contractor to.

What we found in each state

We searched the bigger markets in each state for epoxy, garage floor, and resinous coating installers. Then we read whatever each one posted. Some franchise brands work in more than one state, so the rows overlap a little.

Which exclusions are fair, and which are red flags?

Some exclusions are normal, and ours has them too. A fair warranty on an epoxy floor leaves out accidents, floods, abuse, and roof leaks. It also leaves out damage from other trades, or from a spill no one wiped up.

The trouble starts in two places. One is a clause that names a cause no one can test for. The other is a clause that lets the company be the only judge. So for any clause, ask two things: what would prove it, and who decides? A fair clause names a test with a number. It also promises a written reason inside a set number of days. If there’s no test and the company alone decides, treat it as a red flag.

1. Moisture and “hydrostatic pressure” exclusions with no number

Nearly every warranty we read leaves out moisture from below. That part is fair. A slab that pushes water vapor up through it can break any coating loose. What matters is whether the warranty on your floor names the test that measures it.

Some give a number. One national garage floor franchise leaves out vapor coming off the slab above 8 lbs. That’s pounds of vapor per 1,000 square feet in 24 hours. One Mississippi installer caps it at 3 lbs. One coating maker’s warranty for homes names a meter and a limit: 5.5% on a moisture meter reading. Many give no number at all. Another national franchise leaves out moisture and hydrostatic pressure with no test named. One Tennessee installer leaves out the same pressure and high vapor, again with no number. One Oklahoma installer leaves out hydrostatic pressure from moisture that moves up to the surface.

The worst version we found says no one checks. One Arkansas installer posts a coating maker’s warranty as its written promise on the floor. That paper says the maker takes no part in finding out whether moisture moves through the slab. Put that next to a moisture exclusion and the result is simple: moisture isn’t covered, and no one on that paper has to measure it.

Hydrostatic pressure is liquid water pushing up on the bottom of a slab. Think of groundwater pushing on a basement wall. It does happen. But it takes soaked soil or a water table above the bottom of the slab. The water has to stay there long enough to build pressure. Under most homes and shops, the real problem is something else. Water vapor moves up through the concrete and collects under the coating. No ASTM field test measures that pressure under a floor that’s already down. ASTM F1869, the calcium chloride test, measures how much vapor leaves the surface in 24 hours. ASTM F2170 measures the humidity inside the slab. Neither one measures pressure. So a hydrostatic pressure exclusion with no test named lets the installer blame it after any failure, and you can’t prove it wrong any more than they can. A clause like that isn’t fair to you, because it leaves the installer a way out of almost any claim.

Ask: “What moisture test will you run before you coat? What number does the warranty on my floor use? Will you write the result on my paperwork?” A contractor who never checked for moisture has no fair ground to blame it later. Our moisture testing guide explains both tests.

2. Blanket “cracks” and “deficient concrete” exclusions

Concrete cracks. No coating can hold a moving slab together, so any fair warranty on an epoxy coating leaves out slab movement. But look at how wide the clause reaches. One coating maker’s warranty for homes leaves out cracks and says nothing more. One national garage floor franchise leaves out cracking, heaving, settling, and any ground movement. One Oklahoma installer leaves out deficient concrete, meaning a slab that isn’t up to standard, and faulty structural design.

The problem is the gap between a crack in the slab and a coating that failed at a crack because it never bonded there. A crew that skips crack repair, or grinds poorly along a joint, can still point at the crack.

Ask: “If the coating peels at a crack, how will you tell whether the slab moved or the coating never bonded?”

3. Why does it matter who decides a claim on your floor?

Because the company that pays for the fix shouldn’t be the only judge of whether you get one. One coating maker’s warranty for homes covers only what the maker itself finds defective. It also gives the maker the final word on what its warranty means. One Tennessee installer and one Texas installer both decide claims at their sole discretion. That means they alone decide. Every warranty needs someone to look at a claim. The fair version puts the answer in writing, with a reason, inside a set number of days.

Ask: “Who decides my claim, and how many days do you have to answer? Will a denial come in writing with the reason?”

4. Is labor covered for the full term?

This is where a long warranty often shrinks. One national garage floor franchise covers labor only for the first year after substantial completion. That’s the point when the job is done enough to use. One coating maker’s warranty for homes supplies material only and leaves labor out. The one exception is a recall where the maker finds no mistake in how the floor went down.

Material is the cheap part of a floor repair. The costly part is the labor. The crew grinds out the failed spot, feathers the edges, coats it again, and waits for it to cure. On a garage or shop, that labor often costs several times what the resin does. So a lifetime term that only ships new material to the installer can leave you paying most of the bill. The paperwork will still call that floor covered for as long as you own it. Coating makers write their warranties this way on purpose. The maker didn’t put your floor down, and it won’t pay for someone else’s labor. That’s fair for a maker. It’s also why the installer’s own workmanship warranty matters more than the brand name on the bucket. Ask for both papers, and read which one pays for the crew to come back.

Ask: “For how many years is labor included on my floor? What do I pay if a covered failure happens after that?”

5. How long do you have to report a problem?

This one is the claim clock. One Oklahoma installer asks customers to report problems promptly, with no number. One coating maker’s warranty for homes is clear but tight. It wants a written claim within about 30 days after you found the problem. The clock can also start when you reasonably should have noticed it. That last part matters. Peeling and moisture damage start small. A clock like that can run out before you knew there was a problem to report.

Ask: “When does my clock start, and how many days do I have to report in writing?”

6. Who pays to clear the floor for a repair?

Before a repair, one Oklahoma installer makes the customer clear out the room. That means all the gear and anything else in the way. What that costs depends on the building:

• Home garage: move the cars, the shelves, and the freezer.
• Shop: move lifts, tool chests, and anything bolted down, often with a rented forklift.
• Restaurant or clinic: close for the days the repair and cure take. One coating maker’s warranty for homes also leaves out loss of use.

No one expects a floor contractor to pay a business’s lost sales. But before you sign, you should know who pays to empty the room and how long a repair takes.

Ask: “If a repair is covered, who moves the equipment, and how many days will the area be out of service?”

7. What rights does the warranty on your floor ask you to give up?

This one lives in the fine print. One coating maker’s warranty for homes sends any dispute to a trial in the maker’s home state. That’s more than 700 miles from Oklahoma. It waives trial by jury, so a judge decides alone. It waives class actions too, and it gives you about 90 days after the coverage ends to sue. One national garage floor franchise leaves out special and consequential damages. Those are costs a failure causes beyond the floor itself. The maker’s own paper admits that some states don’t allow some of these limits. Does a warranty on your floor send you to court far from home? Then have a lawyer read it before you count on it.

Ask: “Which state’s law covers the warranty on my floor, and which court hears a dispute? Does it waive a jury trial?”

8. What does “lifetime” mean in the paperwork?

Lifetime almost never means the life of the floor. One national garage floor franchise covers peeling only while the first buyer owns the home, and it doesn’t pass to the next owner. One coating maker’s lifetime term ends when any share of ownership changes hands. It also wants a sign-up form, called a registration, within about 30 days of the install. Miss that, and the owner loses the coverage.

This one isn’t a trap if it’s stated plainly. Ours works the same way. Our lifetime workmanship term runs for as long as the original purchaser owns the property. Federal ad rules expect a lifetime claim to say whose life it means. The trap is a sales pitch that says “lifetime” out loud and hides what it means in the paperwork.

Ask: “Whose lifetime? Does it transfer if I sell? Do I have to register it by a deadline?”

9. Can you be charged for filing a claim?

We didn’t expect this one. The Tennessee installer from clause 3, the one that decides claims at its sole discretion, also charges a fee. If it judges that a claim isn’t a warranty issue, the customer gets a $200 invoice for claim fees. Put those two together and the company both decides the claim and bills you when it says no. A fee like that makes people think twice before they report a real defect.

Ask: “Is there a fee to file a claim on my floor? Who decides whether it counts?”

10. Does anyone cover the installation itself?

This one hides in plain sight. The same Arkansas installer from clause 1 posts only the coating maker’s product warranty on its site. That paper leaves out any defect tied to how the product went down. That’s normal for a maker, since it only made the product. The trap is an installer who hands you that paper as its only written coverage. Poor grinding, a skipped primer, or a coat that went on too thin is the most common reason a floor fails. Under that paper, no one covers it.

Ask: “Which written document covers mistakes in prep and application on my floor, and for how many years?”

How can you tell if a contractor will honor the warranty on your floor?

Look at how they’ve handled claims, as well as what the paper says. The clauses above do the most harm when a company uses them to dodge its own mistakes. If no one tested a floor first, a floor that peels from poor prep can always be blamed on the slab. A fair warranty from people who fight each claim is worth less than a short one from people who come back for the fix.

Three questions tell you more than the length of the term. First, ask for a reference whose floor had a problem, and how the company fixed it. Any contractor with more than a few years of floors has had a callback. One who says otherwise is either new or not being straight with you. Second, ask what they check before they coat. Look for three things: moisture, with ASTM F1869 or ASTM F2170, the surface profile after grinding, and cracks and joints marked for repair. Testing first is what makes a moisture or crack exclusion fair later. Third, ask what they’d say if your floor peeled in year two. Listen to how the answer starts. It might start with “we’d come look at it,” or with a list of things that aren’t covered. The first answer is the one you want in writing.

The same review for other floors

We ran this search for the other floors we put down too, across the same 6 states. Each guide below sums up real, dated terms:

• Polished concrete
• Concrete overlays and resurfacing
• Stained and sealed concrete

We post a plain-English summary of the workmanship warranty on our own floors, including what it leaves out. It leaves out moisture coming up through the slab, and slab cracking and movement. It also leaves out repairs by someone else before we get a chance to look, except emergency repairs. On our epoxy flooring service, we check each slab before we pick a product, and we test for moisture when the check shows a warning sign.
