What a Toronto epoxy floor quote should itemize, and why four of them disagree

Ask four Greater Toronto Area contractors what a double garage runs and the four numbers you hear will hardly line up. Toroo Epoxy Coatings places a 400 to 500 square foot double car garage between $1,500 and $3,000. Armour Guard places a 400 square foot double garage between $1,600 and $4,000. Epoxy Dudes places a two-car garage of 400 to 500 square feet between $3,000 and $4,000. SurfacePro Epoxy Flooring gives $3,800 to $6,800 or more for a 400 square foot two-car garage.

The immediate reaction is to suspect someone is padding the bill. That read is usually mistaken. A realistic Toronto and GTA price band for a double garage runs from about $1,500 to $6,800, set by the coating system, the prep work required and the contractor giving the quote, and all four of those figures sit inside it without stretching.

A warning about tallying sources. SurfacePro Epoxy Flooring operates under Cedarwood Development Group Inc., and both report the same cost of $3,800 to $6,800 for a 400 square foot double garage. That is a single data point with two labels, not two separate confirmations.

GLI Epoxy Flooring and Toroo Epoxy Coatings both identify surface preparation, which means diamond grinding or shot blasting, as the largest single cost factor in an epoxy job. It is also the line item most readily omitted from a quote, since it occurs before any visible work begins.

GLI Epoxy Flooring quotes $1 to $3 per square foot as an add-on for surface preparation covering stains, paint, cracks or moisture. That work is priced as its own line item, measured by the floor, and a headline rate can leave it out without drawing attention. Armour Guard and Epoxy Dudes state that crack repair, oil-stain treatment and taking off an existing coating all push labour and material costs up before the first coat goes down.

That is why GLI Epoxy Flooring advises you to confirm that diamond grinding or shot blasting, crack repair, primer, base coat and topcoat sealer each appear as separate line items. A quote that itemizes them is telling you about the work. A quote with a single figure is telling you about the cost.

With prep work already counted, the coating itself makes up the rest of the range, and it climbs in a clear sequence. In the Toronto market GLI Epoxy Flooring lists solid colour at $5 to $7 per square foot, flake or chip systems at $7 to $10, metallic at $9 to $12 and quartz at $9 to $13. That sequence holds together, and it stands as the clearest published breakdown for this market.

Other sources reach similar figures by separate routes. Sealcon Floor Coatings lists a residential garage span of $5.99 to $12.99 per square foot before tax for the GTA. Monarch Epoxy Coatings sets a basic solid-colour garage floor at $4 to $6 per square foot and a metallic finish at $8 to $12.

A quote therefore responds to two questions simultaneously: how much work this slab requires, and which system you are purchasing. A cheap quote can be cheap on either axis, and only one of those is a saving.

GLI Epoxy Flooring's Ontario guide gives a number to keep in mind: be wary of any quote below roughly $3 per square foot, since that price typically signals a thin coat or no actual diamond grinding.

That fact carries particular weight in Toronto because of the freeze-thaw cycle and the road salt tracked in on tires each winter, which is why contractors in this city push for diamond grinding instead of acid etching. A coating that never bonded properly does not fail slowly; it lifts.

The price of that failure is on record as well. GLI Epoxy Flooring states that redoing a failed DIY epoxy kit professionally, with correct removal and grinding, runs about $2,800 to $3,200 for a double garage. Compared to a quote that saved a thousand dollars by leaving out the grind, the math is not close.

Two adjustments turn a confusing set of quotes into a comparable one.

The first is tax. In Ontario, residential coating work carries HST at 13 percent, and at least one GTA contractor openly states its per-square-foot range before tax. On a job this size, that is a line no one brought up.

Scale is the second factor. Bigger jobs usually run cheaper per square foot because fixed expenses like equipment and travel get distributed across a larger surface, according to GLI Epoxy Flooring and Armour Guard. Sealcon Floor Coatings makes the effect plain: commercial projects above 1,500 square feet cost $1.99 to $8.99 per square foot, while smaller residential work runs $5.99 to $12.99. If you are deciding whether to add the basement while the crew is already there, that difference is the reason to do it in a single visit.

The final step to take is also the least expensive. Use the rate from your quote, apply it to your own floor area, and check that figure against a published project total for a comparable job.

Armour Guard lists precisely that sort of number for an 800 square foot Toronto garage: a basic system runs $5,150 to $8,800, while a premium one runs $8,700 to $13,400. GLI Epoxy Flooring lists a 1,000 square foot basement with a flake system and a moisture barrier at $5,000 to $9,000, and a 600 square foot basement with a metallic finish at $5,400 to $7,200.

If the quote you received sits well under all of those figures, find out which line item explains the difference before you conclude you got a deal.
