How Much Does Epoxy Floor Coatings Cost in Smithtown, NY? (2026 Guide)
Most Smithtown two-car garages land between $2,800 and $5,500 for a full flake system, which works out to roughly $6 to $11 per square foot installed. Published Long Island figures put epoxy floor work at $6 to $10 per square foot and a 500 square foot two-car garage at $3,000 to $4,800, and that matches what we see in Suffolk County. The variables that actually move the number are the condition of the slab, whether it needs moisture mitigation, and how many mils of clear topcoat the floor is asked to carry. Here is how the line items usually break out.
| Service | Typical Smithtown Range |
|---|---|
| Two-car garage, full flake system (400-550 sq ft) | $2,800 - $5,500 |

| Three-car garage or oversized bay (600-750 sq ft) | $4,200 - $7,500 |
| Solid-color epoxy, roll-applied, two coats | $4.00 - $7.00 per sq ft |
| Polyurea-polyaspartic full flake system | $7.00 - $13.00 per sq ft |
| Double-broadcast quartz system | $12.00 - $20.00 per sq ft |
| Diamond grinding and prep, standalone | $1.50 - $4.00 per sq ft |
| Moisture-mitigation primer over a wet slab | $1.75 - $4.00 per sq ft added |

| Basement floor coating (600-1,200 sq ft) | $3,500 - $9,000 |
| Commercial floor, 2,000 sq ft and up | $4.00 - $9.00 per sq ft |
| Slab moisture testing (calcium chloride or in-situ RH) | $150 - $450 per slab |
What Changes the Price?
Slab moisture is the biggest swing. A dry slab needs no mitigation primer; a wet one adds $1.75 to $4.00 per square foot and it is not optional if you want the floor to stay down.
Condition of the concrete: a smooth, sound slab grinds fast, while a pitted, spalled, or previously painted floor needs more passes, more tooling, and resin mortar to fill what grinding exposes.
System choice: a two-coat roll-on epoxy is the cheapest thing that works, a full-broadcast flake with a polyaspartic topcoat runs roughly double, and a double-broadcast quartz floor doubles again.
Access and season: a detached garage with no power, a basement reached by a narrow stair, or a January install that needs the space heated all change the labor number more than the material number does.
Every quote is measured on site and written out by line - prep, crack repair, primer, base, broadcast, topcoat - so you can see what each piece costs and delete anything you do not want. There is no charge for the visit and no deposit taken before you have the number in hand. If the slab tests wet and you would rather not pay for mitigation, we will say so and decline the job rather than coat over it and hope.
