How Much Does Epoxy Flooring Cost for 1,000 Square Feet?
October 2, 2026
At the rates published for Smithtown, the multiplication gives about $4,000 to $14,000 installed. The real budget is that number plus whatever the slab adds to it.
The Short Answer: $4,000 to $14,000 Installed
At the 2026 rates published for Smithtown, epoxy flooring for 1,000 square feet costs about $4,000 to $14,000 installed, labor and materials together, depending on the system that goes down. That figure is simple arithmetic: the published per-square-foot ranges, most of them in the Smithtown epoxy flooring cost guide, multiplied by 1,000. Quartz, a specialty finish, runs higher. By system:
- Two-coat, roll-applied solid-color epoxy at $4.00 to $7.00 per square foot: $4,000 to $7,000
- A full flake floor, published at roughly $6 to $14 per square foot across the cost guide and the service pages: $6,000 to $14,000
- Double-broadcast quartz at $12.00 to $20.00 per square foot: $12,000 to $20,000
What Kind of Floor Is 1,000 Square Feet?
A slab 25 feet by 40 feet is 1,000 square feet, and so is one 20 by 50. That is larger than the Town of Smithtown code allows for an attached garage: section 322-12F caps private garage floor area within a principal building at 750 square feet. A floor this size is therefore more likely a basement, a garage coated together with an adjoining workshop, a detached building or a small commercial bay.
The type of floor decides which published figure applies. For a basement the guide gives a job range, not a per-square-foot rate: $3,500 to $9,000 for 600 to 1,200 square feet, with 1,000 square feet in the upper half of that size band. At 1,000 square feet the solid-color figure and the lower part of the flake figure both fall inside that range, so a basement budget should start from it. The guide's commercial rate of $4.00 to $9.00 per square foot begins at 2,000 square feet, so it does not apply to a 1,000 square foot bay.
A basement or commercial floor coating is specified from the moisture reading and from how long the room can sit empty. A garage-style floor, attached or detached, follows the build on the garage floor epoxy coating page.
What the Slab Can Add at 1,000 Sq Ft
The guide prices testing, moisture mitigation and joint repair as their own lines, apart from the system rate, and on a floor this size the amounts are large enough to plan for:
- Slab moisture testing, by calcium chloride kit or in-situ probe: $150 to $450 per slab
- Moisture-mitigation primer when the slab tests wet: $1.75 to $4.00 per square foot, or $1,750 to $4,000 across the floor
- Cracks and control joints, routed and filled: $8 to $25 per linear foot, so 50 linear feet runs $400 to $1,250
A Worked Budget for a Flake Floor
Start with the flake figure of $6,000 to $14,000. Add a moisture test at $150 to $450, where testing is billed as its own line, and, as an example, 50 linear feet of joint repair at $400 to $1,250. On a dry slab that totals $6,550 to $15,700. If the test comes back wet, the mitigation primer moves the total to $8,300 to $19,700.
That gap is the reason the test comes first. A line worth a few hundred dollars decides whether a four-figure line belongs in the budget at all. Until the reading is in, carry the mitigation figure as a contingency instead of assuming the slab is dry. On Long Island that assumption is the expensive one.
Where Inside the Range a Floor Lands
The system sets the base number, and the spread between systems is wide. Solid color sits at the bottom, quartz carries the highest rate of all and flake runs between them. Choosing between flake and quartz broadcast systems comes down to use: quartz is the finish for floors that get wet by design, such as wash bays and commercial kitchens.
Access and season move the labor. The guide names three cases: a detached garage without power, a basement that can only be reached down a narrow stair and a January job where the space has to be heated. Standard epoxy wants the slab at roughly 55 degrees and rising, so an unheated space in winter means paying for heat, switching to a polyaspartic system with a wider temperature window or waiting for spring.
Two quotes for the same 1,000 square feet can still come back thousands apart, for the reasons covered in what changes the price of a garage floor coating. Prep depth and film thickness in mils are the two specifications to line up before comparing totals.
How to Build the Budget in Order
For an epoxy flooring project in Smithtown, the order of the decisions protects the total more than haggling over the rate does:
- Measure the floor that will actually be coated: length times width for each room, added together
- Have the slab tested before settling on a number, because the result decides the largest add-on
- Choose the system for what the room does, then price that system across the full area
- Keep the mitigation contingency in the budget until the reading clears it
- Ask for the quote by line, with prep method, film thickness and joint work each stated, so every figure can be checked against the work

Quick Answers
How much does it cost to epoxy 2,000 square feet?
For a commercial floor of 2,000 square feet and up, the Smithtown cost guide gives $4.00 to $9.00 per square foot, which is $8,000 to $18,000 at exactly 2,000 square feet. Quartz is priced on its own row at $12.00 to $20.00 per square foot, and a moisture-mitigation primer, where the slab tests wet, adds $1.75 to $4.00 per square foot.
How much does it cost to epoxy a 1,000 square foot basement?
The Smithtown cost guide lists basement floor coating at $3,500 to $9,000 for 600 to 1,200 square feet, and a 1,000 square foot basement sits in the upper half of that size band. A below-grade slab is specified from its moisture reading, and a wet result adds a mitigation primer at $1.75 to $4.00 per square foot, or $1,750 to $4,000 on 1,000 square feet. Testing before pricing keeps that from arriving as a surprise.
Can a DIY kit cover 1,000 square feet for less?
In materials, yes, but it is not the same floor. A store kit lays roughly 3 to 5 mils of film, against 15 to 25 mils for a typical residential system and 20 to 30 for a full flake broadcast. Kits also assume a dry slab and a surface profile that acid etching does not reliably produce, and on Long Island slabs neither is safe to assume.
