What epoxy garage floor costs

Prices in this category are quoted per unit — per square foot, per linear foot, per pier, per job — and the unit is where most quotes become incomparable. The table below is the range we verified in November 2026, with what each line includes.

Job	Typical range	Notes
Epoxy kit, DIY	$3–$7 / sq ft	Includes flakes and topcoat
Professional epoxy	$5–$12 / sq ft	Grind, prime, base, topcoat
Polyaspartic system	$8–$15 / sq ft	Fast cure, UV stable
Metallic epoxy	$10–$20 / sq ft	Decorative, skill-heavy
Concrete grinding	$1–$3 / sq ft	Prep, often excluded
Moisture mitigation	$2–$5 / sq ft	When a vapour barrier is missing

What moves the price

• Access. Height, water, tight side yards and finished interiors all add labour.
• Prep. Cleaning, grinding, draining or removing an old system is often the largest hidden line.
• Materials. The same job in a premium finish can double the material cost.
• Permits and disposal. $100–$800 depending on the jurisdiction and the waste stream.
• Season. Spring and autumn are busy; February is not.

What a quote should show

Ask for the same five lines from every contractor: unit price and quantity, prep included, materials by brand, permits and disposal, and the warranty. A quote that only shows a total is a price, not a scope.

The methods hub explains what each option actually does, and the problems hub starts with the diagnosis every quote should follow.

Is the cheapest quote a red flag?

Usually it is a scope difference — less prep, no permit, thinner material. Compare the five lines, not the total.

How long is a quote valid?

30 days is common; material prices move. Ask what happens if you sign after the window.
