What garage floor epoxy coating costs in Ontario, and what changes the price

Ask five installers to quote the same garage and you can end up with five different numbers. That is normal in this trade. The floor itself, the finish you pick, and how much prep the concrete needs all move the price, sometimes by a thousand dollars or more on an identical-looking garage. Here is what actually drives the number, with typical Ontario ranges for each piece.

Start by getting a feel for the categories in the garage floor coating hub, where you can compare installers by rating and see what past customers said about their pricing and finish quality.

What drives the price

Three things set the quote: floor size, coating type, and current floor condition. Size is the easy one, most installers price per square foot once they know the coating system. Coating type and condition are where the spread comes from.

• Coating type. A basic two-coat epoxy costs the least. Add a flake broadcast finish (the coloured chips scattered into the top coat) and the price climbs roughly 25 to 30 percent over basic epoxy. Move to a polyaspartic or polyurea system and expect another 15 to 20 percent on top of that, mostly paying for a faster cure and better UV stability.
• Floor condition. A slab with no cracks or staining costs the least to prep. Minor cracks or oil stains add roughly 10 to 15 percent to the job for patching and degreasing. Significant cracking or spalled concrete can add 30 percent or more, since it needs grinding and structural patching before any coating goes down.
• Access and prep logistics. A detached garage with easy equipment access is cheaper to work in than a finished garage full of storage that needs to be emptied and the space ventilated for fumes.

Typical price ranges by finish

These ranges reflect the kind of pricing spread installers report across Ontario garages of common sizes. Treat them as a starting point for budgeting, not a quote.

Garage size	Basic 2-coat epoxy	Flake broadcast epoxy	Polyaspartic
Single-car (~250 sq ft), good condition	$1,000 – $1,300	$1,300 – $1,700	$1,550 – $2,000
Double garage (~400–500 sq ft), minor cracks	$1,900 – $2,700	$2,400 – $3,900	$2,850 – $4,500
Double garage, significant cracks or damage	$2,600 – $3,900	$3,300 – $5,300	$3,900 – $6,000

Larger garages and triple bays scale up from the double-garage figures roughly in proportion to square footage, with a small per-square-foot discount for bigger jobs.

Why floor condition matters more than most people expect

Concrete that looks fine can still fail a moisture or adhesion test. Older Ontario garage slabs, especially ones poured before proper vapour barriers were standard, sometimes trap moisture that pushes coatings up from underneath months later. A contractor who tests for this before quoting is doing you a favour, even if the quote comes in higher than a competitor who skipped the test. Ask directly whether the price includes moisture testing and crack repair, or whether those get added once the crew is on site.

Basic epoxy vs flake vs polyaspartic: picking by value, not just price

Basic epoxy is the budget option and works fine for a garage used mainly for parking, with light wear and no heavy chemical exposure. Flake broadcast systems cost more but hide dirt, tire marks, and minor imperfections far better, which matters if the garage doubles as a workshop. Polyaspartic costs the most up front but cures in a fraction of the time, so if you cannot afford a week without garage access, the extra cost often pays for itself in convenience alone.

How to avoid overpaying

Get at least three quotes and ask each installer the same three questions: what prep is included, how many coats, and what the warranty covers. A quote that looks cheap because it skips grinding or moisture testing usually costs more later when the coating lifts. Compare the coverage, not just the bottom line. Once you have picked a finish and a price you are comfortable with, our step-by-step installation guide covers what a crew actually does on site, from prep to final cure.

Financing and payment

Financing is common enough in this trade that it is worth asking about even if an installer does not mention it. Some offer in-house payment plans over three to six months; others partner with a financing company for longer terms. If cost is the main barrier, ask before you rule an installer out. This guide is general cost information, not a substitute for a written, itemized quote from a licensed installer.
