How to Vet an Epoxy Flooring Contractor
Last updated: August 2026
The floor itself is only half the job — who installs it decides whether it lasts 20 years or peels in two. Here’s exactly what to ask, check, and watch for before you sign anything.

Watch For These
Five Red Flags Before You Sign
Most bad epoxy jobs trace back to one of these being ignored during the hiring process, not a bad batch of material.
No Mention of Grinding
If a quote describes “acid etching” or doesn’t mention mechanical prep at all, walk away — that’s the #1 cause of early peeling.
No Moisture Testing Offered
Especially for basements or slabs on grade. Coating over untested moisture is one of the most common failure causes we get called to fix.
Verbal Quote, No Paper
A legitimate contractor gives you an itemized written estimate. “I’ll just text you a number” is a sign there’s nothing to hold them to later.
Same-Day, Same-Coat Pressure
A quality install takes 2+ days minimum for prep, base, and topcoat with proper cure time between steps. “In and out in a few hours” means shortcuts.
No Warranty, or a Vague One
“We stand behind our work” isn’t a warranty. Ask for the specific term in writing — years, what’s covered, what voids it.
Full Payment Upfront
A deposit is normal. Being asked for 100% before any work starts removes your leverage if something goes wrong mid-project.
Come Prepared
Six Questions Worth Asking Directly
Click a question to see what a good answer sounds like — and what a bad one sounds like.
“What does your surface prep involve?”
Good answer: “Diamond grinding to open the concrete pores, plus crack repair before any coating goes down.” Bad answer: “We acid-wash it” or a vague “we clean it well first.”

Before You Compare Prices
What a Real Quote Should Include
Two quotes with wildly different prices are often not quoting the same job. Before you compare numbers, check that both actually cover these same items — otherwise you’re not comparing apples to apples. See our full cost guide for what realistic 2026 pricing looks like.
Get an Itemized Quote-
Named prep steps, not just “prep included”
Grinding, crack repair, and moisture testing should each be spelled out, not bundled into one vague line.
-
The specific coating system by name
“Epoxy coating” alone could mean anything from a thin single-coat to a full flake broadcast system — ask which.
-
Total square footage and price per square foot
Lets you sanity-check the math yourself instead of trusting a single lump sum.
-
Timeline, including cure time before use
Should state install days plus how long before you can walk on it and park on it.
Paperwork That Protects You
Three Things to Verify, Not Just Ask
Licensed & Insured
Ask for proof, not just a claim. If they hesitate to provide it, that’s your answer. Insurance matters most if something is damaged during the job.
Real, Local Past Work
Ask to see floors they installed 3–5 years ago, not just fresh photos. A floor that still looks good after a few years tells you more than a brand-new one.
Reviews That Mention Specifics
Generic 5-star reviews are easy to gather. Look for ones that mention punctuality, communication, or how an issue was actually resolved.
Every Prime Coat Floors estimate includes proof of license and insurance, a written itemized quote, and a clear breakdown of cost before you commit to anything — because we’d rather you ask these questions than find out the hard way.
A Quick Gut Check
Why the Cheapest Quote Is Usually the Riskiest
Grinding equipment, quality material, and trained labor all cost money — there’s a floor beneath which a quote simply can’t include real prep and still turn a profit. When one bid comes in far below the others, the difference is usually coming out of the prep work, not the contractor’s margin.
That doesn’t mean the highest bid is automatically the best either. Use the questions above to figure out what each price actually includes, then compare like for like — not just the bottom-line number. See how epoxy floor lifespan differs between a properly prepped floor and a rushed one.

Hiring Questions We Get Asked Most

Get a Free Estimate- Ask for proof of license and insurance, a written itemized quote, and examples of work at least 3–5 years old. A legitimate contractor won’t hesitate to provide any of these.
- Yes — two or three, so you can compare what each one actually includes, not just the bottom-line price. Use the quote checklist above to make sure you’re comparing the same scope of work each time.
- For a basement or any slab on grade, yes — that’s one of the clearest signs a contractor is skipping a step that prevents the #1 cause of early failure. It’s worth asking directly if they don’t bring it up.
- Usually because they’re not quoting the same job. The gap almost always comes down to how much surface prep, what coating system, and what warranty each price actually includes — not the contractor simply being cheaper or pricier for the same work.
- An itemized price, named prep steps, the specific coating system, the timeline including cure time, and the warranty term and coverage. If any of that is missing or vague, ask for it before signing.
