What Should Be on an Epoxy Garage Floor Quote? A Line-by-Line Guide
We won't post a number here on purpose - every slab prices differently. Here's what an honest written quote names, so you can tell a real bid from a lowball.
The most useful thing we can hand you here isn't a number - it's a checklist for reading whatever number you get. Two garages that look the same can price very differently once someone actually assesses the concrete, and two contractors can quote the identical job wildly apart depending on what is quietly left off the page. Walk through the line items below before you sign anything.

The line items an honest quote always names
Before comparing totals, check that each bid actually spells out the same five things. If any of these is missing or vague, the total is not comparable to one that includes it:
- Grind, not etch. The prep method should be named specifically - full diamond grinding, not "surface prep" left undefined.
- Repair scope. Whether crack routing and pit fill are included in the number, or billed separately once the crew starts.
- Base coat and topcoat, both. Some bids price only the base and treat the clear topcoat as an upsell.
- The finish. Solid color, flake broadcast, or metallic - named, not assumed.
- Cleanup and disposal. Ground concrete dust and old coating debris have to go somewhere; that should not be a surprise line item.
How a lowball quote hides its gaps
The number that looks best on the page is sometimes the one missing the most. The two quiet tricks worth knowing: pricing an "acid etch" instead of a real grind (etching opens the surface chemically, not mechanically, and coatings bond to it far less reliably), and quoting the base coat while treating the topcoat, the actual UV-stable, wear-resistant layer, as an add-on discovered on install day. Neither shows up as a lie on paper - they show up as a callback a few weeks later asking for more money to finish what you thought was already priced. Reading the checklist above before you compare totals is what catches this.
The short version
Compare what's named, not just the total. An itemized quote naming grind, repair, base, topcoat, and cleanup protects you from a number that grows after the crew arrives.
What actually moves the number, in pairs
A sound slab vs. one that needs real repair. Clean concrete with a few hairline cracks takes far less labor than a floor with active pitting or spalling that needs routing and fill before anything else can happen - see our guide on what pros do with a pitted or spalled slab if that sounds like yours.
Solid color vs. full decorative flake vs. metallic. Each step up uses more material and more labor time; our finish options guide shows what each actually looks like installed.
Basic epoxy vs. a polyurea-and-polyaspartic system. Different chemistry, different price point, and a very different number of years before you are having this conversation again - the full breakdown is in our polyaspartic vs epoxy guide.
A small single bay vs. a larger multi-car footprint. Bigger jobs often see the per-square-foot rate ease slightly, since crew setup and mobilization spread across more area.
The DIY math, if you're tempted
A box-store kit is the cheapest line item you will find anywhere in this comparison, and that is exactly the problem: thin water-based epoxy applied over an acid-etched rather than ground slab is the single most common cause of hot-tire peeling within a year or two. At that point a professional still has to grind the peeling film back off the slab before anything real can be installed, so the DIY route quietly bills you for prep a second time. We lay out that comparison in more detail in DIY epoxy kit vs. pro install, and in the bigger-picture math in is a coating worth it at all.
Ask about these two add-ons up front
Two extras show up on most real quotes, and a good written bid itemizes both rather than surprising you with them later: coating the stem walls (the low concrete lip that rings the garage's edge, just below where the drywall starts) to match the floor, and coating steps or stairs in the same finish. Neither is required, but both should be a clear line on the page, priced or explicitly declined, not a verbal add-on after the fact.
Getting your real number
An online calculator that asks for your email before showing a figure is a lead form wearing a calculator's clothes, and the number it produces is still a guess made without ever seeing your slab. If you are in Waukegan or anywhere in Lake County, we measure the floor and assess the concrete in person, free, and confirm a written, itemized number the same day - no email trade required to get it. Still weighing whether a coating is the right move at all? Our garage flooring options comparison lays out the alternatives. Ready for the real number?
