How Much Does Epoxy Flooring Cost in Great Falls, MT? (2026 Guide)
Published figures for Montana and the northern plains put most residential epoxy work between $4 and $10 per square foot installed, with full-broadcast flake garage systems for a two-car garage typically landing between $2,500 and $5,000. Decorative metallic floors run higher, usually $8 to $14 per square foot, and industrial systems for shops and ag buildings range from about $6 to $14 depending on build thickness and chemical exposure. Those brackets are wide because prep is the swing factor: a sound slab that needs a grind and two coats sits at the bottom of a range, while a pitted, previously-sealed floor that needs repair mortar and a moisture-tolerant primer climbs toward the top. The table below shows how the numbers usually break out around Cascade County.
| Service | Typical Great Falls Range |
|---|---|
| Two-car garage, full flake system (approx. 400-500 sq ft) | $2,500 - $5,000 |
| Single-bay or one-car garage | $1,500 - $2,800 |
| Residential interior epoxy (basement, laundry, mudroom) | $4 - $10 per sq ft |
| Decorative metallic or designer flake system | $8 - $14 per sq ft |
| Commercial epoxy (retail, kitchen, clinic, office) | $5 - $12 per sq ft |
| Industrial shop, fab bay or ag building system | $6 - $14 per sq ft |
| Concrete grinding and surface prep only | $1 - $3 per sq ft |
What Changes the Price?
Slab condition drives everything: freeze-thaw pitting, spalls, open cracks and old sealers all add prep hours before the first coat, and prep is priced as its own line so the why is visible.
System choice moves the number: a solid-color utility coat, a full flake broadcast with polyaspartic top, and a metallic showpiece are three different budgets on the same square footage.
Heated versus unheated space in winter: cold-season installs need the slab held in the product window, so an unheated detached garage in January may wait for spring or price in temporary heat.
Travel radius: small jobs out toward Fort Benton, Choteau, Conrad or Stanford carry a stated small-job minimum, since grinders and material ride an hour each way. Larger rural shops absorb the miles easily.
Treat every figure above as a bracket, not a bid. Trust one number: the figure put in writing once the slab gets measured, moisture-checked and honestly assessed. That quote costs nothing. Grinding, repairs, every coating layer and the topcoat each show as their own line, which makes stacking it against another bid easy. If coating a given floor does not pencil out, that gets said plainly before any money changes hands.
