How to Choose a Garage Floor Coating Company

To choose a garage floor coating company, verify four things: that they diamond grind rather than acid etch, that they test the slab for moisture before quoting, that they carry liability insurance and WorkSafeBC coverage, and that their warranty specifically names peeling and delamination. Everything else is preference. Those four separate a floor that lasts from one you pay twice for.

The short answer

The hard part of hiring here is that the most important work is invisible by the time you see the result. Every floor looks good on install day. The difference between a good contractor and a bad one only shows up in year two — which is exactly why the questions below matter more than the photos in someone's gallery.

The eight questions

1. How will you prepare my concrete? You want to hear diamond grinding. Acid etching and pressure washing are shortcuts that leave the slab too smooth for a lasting bond.
2. Do you test for moisture before quoting? In this climate the answer needs to be yes, with a clear explanation of what happens if readings come back high.
3. What exactly is the system? Ask for the layers by name. A vague "epoxy floor" answer is different from "grind, epoxy base, full flake broadcast, polyaspartic top coat."
4. Is it a full broadcast or a partial one? Partial flake uses less material and leaves a thinner, less uniform floor. Full broadcast is what gives you the depth and traction.
5. What does the warranty actually cover? "Lifetime warranty" means nothing on its own. You want peeling and delamination named explicitly, with a stated term.
6. Are you insured and WorkSafeBC covered? Ask for proof, not reassurance. Uninsured crews working in your home are your liability.
7. Who does the work? Owner-operated crews and subcontracted labour behave differently. Neither is automatically bad — but you should know which you're getting.
8. Can I see recent local work? Photos from the manufacturer's catalogue are not the same as floors this crew installed nearby.

Red flags

How to compare quotes fairly

Quotes are rarely comparable as written, because they're often describing different jobs. Before you compare numbers, normalise them: same prep method, same number of layers, same flake coverage, same warranty term.

Once you do that, a suspiciously low quote usually reveals itself — it's cheaper because it's less work. And redoing a failed floor costs more than the gap you saved, because you pay for grinding off the old coating on top of the new install. Our cost guide breaks down what drives the price in the Lower Mainland.

For what it's worth, this is why we quote on site rather than over the phone, bring flake samples to every visit, and put the layer stack in writing.

Frequently asked questions

What should I ask a garage floor coating company before hiring?

Ask how they prepare the concrete, whether they moisture-test before quoting, what the full layer system is, what the warranty names specifically, and whether they carry liability and WorkSafeBC coverage.

Is diamond grinding necessary for a garage floor coating?

Yes. Grinding opens the concrete so the coating bonds mechanically into the slab. Acid etching and pressure washing leave the surface too smooth, which is the leading cause of coatings peeling later.

Why are some garage floor quotes so much cheaper?

Cheaper quotes usually mean less work — skipped grinding, partial flake coverage, thinner material or fewer layers. The saving disappears if the floor fails, since removal is added to the cost of doing it properly.

Should I get a quote over the phone?

A ballpark range is fine, but a firm price without seeing your slab isn't reliable. Concrete condition is one of the biggest cost drivers, and nobody can assess it remotely.
