How to Find a Qualified Epoxy Flooring Contractor

Your garage floor is peeling. Or you want that showroom finish you’ve been seeing in every home improvement video. Either way, you’ve decided to hire a pro — smart move. But “epoxy contractor” covers a massive range: from skilled applicators who’ve coated thousands of floors, to handymen who bought a kit from Home Depot last month and called themselves contractors.

Finding the right one takes about two hours of work upfront. Skip that work and it costs you thousands on the back end.

Where to Look (and Where Not To)

Manufacturer certification directories are the most underused resource in the industry. Sherwin-Williams, Rust-Oleum (professional division), Tennant, and ArmorPoxy all maintain lists of certified installers who’ve been trained on their specific coating systems. If a contractor is on one of those lists, you know at minimum they’ve received formal product training. Start here.

Angi (formerly Angie’s List) has a contractor-search feature with verified reviews. According to Angi’s own data, contractors with 20+ verified reviews and a 4.5+ star rating have a significantly lower dispute rate than unreviewed listings. Use it for discovery, but don’t rely on it alone — reviews can be gamed, and “epoxy flooring” in their category lumps together wildly different skill levels.

National trade associations like the Painting and Decorating Contractors of America (PDCA) and the International Concrete Repair Institute (ICRI) list member contractors. ICRI in particular focuses on concrete surface preparation — which is the single most important part of any epoxy job.

Local flooring showrooms often have referral relationships with installers. It’s not as neutral as a directory, but a showroom that stands behind its referrals has skin in the game.

Where to avoid: Facebook Marketplace, Craigslist, and door-to-door solicitations are where the lowest-quality operators concentrate. That doesn’t mean every Craigslist contractor is bad — but your ability to verify credentials and hold them accountable drops dramatically outside of established platforms.

The Vetting Process: What to Actually Do

Don’t just collect names. Run each one through this process before you invite anyone to your property.

Step 1: Verify business existence. Google their business name plus your state. A legitimate contractor has a registered business entity, a real address, and at minimum a basic web presence. If you can’t verify they exist as a company, stop there.

Step 2: Check the BBB. The Better Business Bureau isn’t perfect, but it’s a fast way to spot patterns. A contractor with three “failure to honor contract” complaints in two years is telling you something. BBB accreditation alone means little; look at the complaint history, not the grade.

Step 3: Ask for proof of insurance. General liability (minimum $1 million per occurrence) and workers’ compensation are non-negotiable. If they balk at this request, that’s your answer. Real contractors carry certificates they hand out routinely.

Step 4: Request references from jobs similar to yours. Not a list of 10 names from five years ago. Specifically ask: “Can I speak to someone whose garage floor you coated in the last 12 months?” Then call. Ask about prep time, dust and mess management, whether the crew showed up as scheduled, and how the floor looks today.

Questions to Ask Before You Commit

You’re not being difficult by asking these. Any contractor who’s been doing this for more than a year has heard them all and has good answers ready.

• What surface prep method do you use — diamond grinding or acid etching? (Diamond grinding is the professional standard; acid etching is cheaper and far less reliable.)
• What’s the solids content of your epoxy? (Anything under 90% solids is a red flag for a “professional” system.)
• How thick will the finished system be in mils?
• What’s your warranty, and is it from you or the manufacturer?
• Who does the work — your crew or subcontractors?
• What’s your timeline from deposit to finished floor?

That last question matters more than people realize. A contractor who says “we’ll be done in 4 hours” on a two-car garage with proper prep is leaving something out.

Red Flags That Should End the Conversation

• They quote a price over the phone without seeing the floor.
• They push you to decide today to “lock in pricing.”
• They can’t produce a certificate of insurance on request.
• The quote is below $2.50 per square foot for installed professional epoxy.
• They describe their product as “epoxy” without being able to name the manufacturer or solids percentage.

Getting Multiple Quotes

You need at least three quotes. Not because you should always pick the cheapest — you absolutely shouldn’t — but because the quoting process itself reveals how a contractor thinks and communicates. A contractor who asks good questions, measures carefully, and provides a detailed written proposal is demonstrating competence before they ever touch your floor.

HomeAdvisor’s 2024 data shows that homeowners who got three or more quotes on flooring projects saved an average of 14% compared to those who accepted the first quote — and reported higher satisfaction with the work quality.

The 3-quote rule for epoxy flooring isn’t about price shopping. It’s about information gathering.
