DIY vs. hiring a pro
How to Choose an Epoxy Contractor: The Full Checklist
Short answer: ask about prep method (grinding, not just etching), moisture testing, product solids content, licensing/insurance, and get the warranty in writing — a quote that skips any of these is worth a second look before you sign.

You've decided to hire a pro — good. Now the question is which one. A legitimate epoxy contractor should welcome every question below; hesitation or vague answers are the actual signal to watch for, more than price alone.
DIY if…
- You're reconsidering DIY after reading the vetting bar below — worth revisiting the full decision guide
- A qualified contractor is hard to find in your area and the DIY case looks stronger by comparison
Hire a pro if…
- You've found a contractor who clears every item on this checklist
- That's exactly the outcome this page is meant to help you reach
Questions to ask before you sign anything
- How do you prep the slab? The answer should be mechanical diamond grinding, not acid etching alone — see why this matters.
- Do you test for moisture, and what happens if it fails? They should have a real answer beyond "we haven't had an issue."
- What product and solids percentage do you use? 100%-solids epoxy or polyaspartic outperforms retail-tier water-based products — see what solids content means.
- Are you licensed and insured? Ask to see proof, not just a verbal yes.
- What's the warranty, in writing? Get specific coverage and duration — a verbal "we stand behind our work" isn't a warranty.
- Can I see photos of similar completed jobs? A contractor with real experience will have these readily available.
Red flags to walk away from
- A quote with no mention of surface prep or moisture testing at all
- One-day-completion promises — proper prep, coating, and cure genuinely takes several days
- No written estimate, or reluctance to put the warranty in writing
- Pricing dramatically below every other quote you've gotten (a real red flag, not a deal)
- Pressure to sign same-day without time to compare quotes
