A $4,000 quote on a 2-car garage breaks down roughly like this: $900 in materials, $700 in grinding and prep, $1,800 in labor, and the balance in overhead, warranty, and insurance. Here is the full line item so you can see where every dollar goes.
Customers ask me this all the time, usually politely, sometimes not: why is it $4,000? It's a fair question. I'd rather show you the math than dodge it, so here is an actual breakdown on a standard 450 sqft 2-car garage.
Why $4,000 and not $2,000?
A proper polyurea/polyaspartic floor is a two-day job for two installers with serious equipment. The quote is not one guy with a paint roller. Let's walk it.
Line 1: Materials
The Valence Covalent Flake System uses three products: a 100% solids polyurea basecoat, a broadcast flake, and an 85% solids polyaspartic topcoat. On 450 sqft, materials run about:
- Polyurea basecoat: $350 to $420
- Flake (color blend, full broadcast to rejection): $180 to $220
- Polyaspartic topcoat: $280 to $350
- TerraMend crack filler and patch material: $40 to $80
Total materials: roughly $850 to $1,070. This is real product cost, not marked-up line items. I buy direct from Valence in Mendota Heights because I'm a Valence Certified Installer, and I wrote about that in why we use Valence.
Line 2: Surface prep and grinding
This is the line that separates a floor that lasts 20 years from a floor that fails in 3. We diamond grind the entire slab to a CSP 2-3 profile, which means the concrete surface looks like rough sandpaper up close. That profile is what lets the polyurea actually bond.
- Diamond grinder wear (tooling is expensive and consumable): $120 to $180
- HEPA vacuum filter and bag cost: $30 to $50
- Grinder fuel/electric cost and generator wear: $20 to $40
- Labor: 3 to 4 hours of grinding, 1 to 2 hours of edging
You are looking at about $650 to $800 on this line once you count the physical cost of wearing out $6,000 diamond tooling. More on this in surface prep and repair.
Line 3: Crack repair and patching
Most 2-car garages in western Wisconsin have 2 to 6 hairline cracks and a spot or two of surface spalling near the garage door. On a standard quote, crack repair for hairline through 1/4-inch cracks is included. Larger cracks or full-depth spalling adds to the quote, but on most homes we are talking:
- Crack chase-out and fill: 30 to 60 minutes
- TerraMend material: already counted above
- Patch cure and re-grind: 20 to 30 minutes
Call it $100 to $150 of labor time on the average job.
Line 4: Install labor
A 2-man crew on a 1-day polyurea install puts in about 16 labor hours between the two of them, not counting grind time. Cut in the edges, roll the basecoat, broadcast the flake to rejection, scrape back the excess the next morning, roll the polyaspartic topcoat.
At honest working-wage rates plus payroll taxes and workers comp, install labor runs $1,600 to $2,000. This is the biggest line on any legitimate quote, and if someone is quoting you a number where the labor doesn't pencil out, somebody is getting shorted - usually you, on prep time.
Line 5: Overhead, insurance, warranty reserve
Here is the part no contractor likes to talk about, so I will. Running a legit business means paying for:
- General liability insurance: a real policy, not a certificate that lapsed last year
- Vehicle and trailer costs, fuel, maintenance
- Valence training and certification renewals
- Warranty reserve - money set aside against the 15-year warranty
- Phones, software, the time I spend on the drive out to your house to quote it
On a $4,000 job, overhead and warranty reserve is usually $400 to $600. That is what keeps the business standing behind the floor in year 8.
Putting it all together
Materials $950 + Prep $725 + Crack work $125 + Labor $1,800 + Overhead/warranty $500 = $4,100 on a typical 2-car garage.
That is why the number is what it is. It is not a markup game. It is what the job actually costs when it is done right with the right materials.
Where quotes go wrong
When you see a $2,000 quote from another installer, one of these things is happening: they are acid etching instead of grinding, they are using water-based epoxy, they are skipping the topcoat, or they are not insured. Sometimes all four. I covered more of this in the Wisconsin cost guide.
