How to Vet a Garage Floor Coating Contractor in Kenosha: A Local Checklist
Wisconsin does not license floor coating as a trade, so the vetting is on you. Here is the checklist we would use on ourselves - insurance, prep, system, and warranty, in that order.
Here is the fact most Kenosha homeowners do not know when they start calling around: Wisconsin has no trade license for garage floor coating contractors, and most coating jobs never touch a building permit. The state vets electricians and plumbers for you. For a coating crew, nobody is checking their work but you. The good news is that four questions - insurance, prep method, coating system, and warranty terms - will sort a career installer from a spring paint crew in one phone call. This checklist walks through each one, what a good answer sounds like, and the free ways to verify what you are told.
TL;DR
Wisconsin does not license floor coating as a trade, so vet the installer yourself: ask for a current certificate of liability insurance and workers' comp coverage, require diamond grinding (not acid etching) as prep, get the system named layer by layer, and read what the written warranty excludes. Check any state contractor credentials on the DSPS site and read their worst reviews first. Then compare bids on scope, not bottom line.

What does Wisconsin actually license, and where does that leave coatings?
Wisconsin regulates building trades through the Department of Safety and Professional Services (DSPS). Electricians, plumbers, and HVAC contractors carry state credentials, and contractors who pull permits on homes hold a dwelling contractor certification. Floor coating sits outside all of that. There is no coating-specific license, and grinding and coating an existing slab does not normally require a permit in Kenosha or the surrounding towns. That is not a loophole anyone is exploiting - it is just how the trade is classified - but it means the barrier to entry is a van and a sprayer. If a company tells you they are "fully licensed for epoxy work in Wisconsin," that phrase should sharpen your attention rather than relax it, because there is no such license to hold. What a straight operator says instead: we are insured, here is the certificate, and here is exactly what we do to your slab.
What insurance proof should I ask a coating contractor for?
Two documents, and both are ordinary requests that no legitimate installer will resent. First, a current certificate of general liability insurance. If a grinder gets away from someone and takes out your water heater, or a coating fails and takes drywall repair with it, liability coverage is what pays. Ask for the certificate itself, issued by the insurer or their agent - not a sentence on a website. Second, ask whether everyone working on your floor is covered by workers' compensation. If an uninsured worker is hurt in your garage, you do not want to be the deepest pocket standing nearby. A real company can produce both within a day. While you wait, two free checks: look the company up on the DSPS credential search if they claim any state contractor certification, and read their Google reviews sorted worst-first, because the one-star stories tell you how they handle a problem, which matters more than how they handle a compliment.
Which three questions expose a paint crew fastest?
One: how do you prep the slab? The only answer that should survive is diamond grinding. Acid etching is faster and cheaper, and coatings laid over etched concrete are the ones peeling in Kenosha garages three winters later. Around here the slab has usually absorbed years of road salt, and grinding is what opens the surface so a coating can grab it mechanically. Our garage floor coating installation page shows the full sequence step by step.
Two: what exactly goes on the floor? You want the system named layer by layer: what the base coat is, what carries the flake, what the topcoat is. A strong answer for this climate is a polyurea base with a polyaspartic topcoat, because the topcoat is UV-stable and cures in hours. A weak answer is "commercial-grade epoxy" with no other nouns. If the word epoxy is doing all the work in their pitch, read our epoxy garage floor page first so you know what to ask next.
Three: what does the written warranty exclude? Everyone claims a warranty on the phone. The document is where you learn whether it covers adhesion failure and hot-tire pickup, whether it is prorated into uselessness, and whether the company plans to exist long enough to honor it. Ask to see the actual warranty language before you sign, not after.
The Kenosha vetting checklist, in one table
Print this or keep it open during the call. Every row is a question you are allowed to ask, and none of them should offend an installer who does this for a living.
| Check | What to ask for | A good answer looks like |
|---|---|---|
| Liability insurance | A current certificate of insurance | The certificate arrives from the insurer or their agent within a day |
| Workers' comp | Confirmation the crew is covered | A plain yes, with the policy on the same certificate |
| State credentials | Any DSPS contractor certification they claim | A name you can verify on the DSPS site - or an honest "coatings are not a licensed trade" |
| Prep method | How the slab is prepped | Diamond grinding, with dust extraction - never acid etching alone |
| Moisture check | Whether the slab is tested before coating | Yes, especially on basement floors and older slabs |
| System | Every layer, named | Base coat chemistry, flake broadcast, topcoat chemistry, in order |
| Repair scope | How cracks and pits are handled | Chased, filled, and patched before coating - listed in the bid |
| Warranty | The written terms | Covers adhesion and hot-tire pickup; exclusions in plain English |
| Track record | Reviews and time in business | Consistent reviews across seasons, worst ones handled professionally |

How do I compare coating bids without getting burned?
Compare scope, not bottom lines. Two bids for the same Kenosha garage can sit far apart because one includes crack repair, a full grind, and a two-coat build with a polyaspartic topcoat, and the other is a single coat over an etch. The cheap one is not cheaper - it is a different, smaller job that happens to be printed on the same size paper. Line the bids up row by row against the checklist above and make each contractor point to where the bid covers prep, repair, layers, and warranty. What moves the figure itself - size, slab condition, repair, system, finish - is a separate subject, and we keep the honest version of it on our garage floor cost page, with zero made-up numbers.
The last filter is the visit itself. An installer who quotes your floor without standing on it is guessing, and a guess cuts one of two ways: padded to protect them, or lowballed to win you and adjusted later. Every floor we quote gets measured and read in person, free, and you get the scope in writing so you can hold it against any other bid on your kitchen table. That is the vetting working exactly as it should - request a free on-site quote and bring the checklist.
