It's the first question everyone asks, and the honest answer is that it depends on your floor. Two garages the same size can be priced very differently. Here's what actually drives the cost, so you can make sense of any quote you get in London or Southwestern Ontario.
What affects the price
- Size: the square footage of the floor is the starting point. A single-car garage, a double and an oversized triple are very different jobs.
- Concrete condition: cracks, spalling, pitting and uneven spots all need repair before coating.
- Old coatings or paint: anything already on the floor has to be ground off first.
- Moisture: slabs with moisture coming up through them, common in basements, need more care.
- The system: a full flake broadcast with a clear polyaspartic topcoat is a different product from a single coat of paint-on epoxy.
- Extras: stairs, landings and curbs add time.
Why the cheapest quote can cost more
The easiest places to cut cost are the ones you can't see once the floor is done: grinding, crack repair, primer and the topcoat. A floor that skips them can look identical on day one and start peeling within a couple of years. Removing a failed coating and starting over usually costs more than doing it properly the first time.
How to compare quotes
Ask each company to spell out what's included, then compare line by line:
- Diamond grinding, or just cleaning or acid etching?
- Crack and concrete repair included?
- Primer or vapour barrier coat?
- Full flake broadcast or a light sprinkle?
- Clear polyaspartic topcoat, or epoxy on top?
- How many days, and how long does each layer cure?
- What does the written warranty cover?
