Short answer: It's one of the most common questions we hear: you get three estimates for the identical garage and they're miles apart. That gap almost never means someone is ripping you off — it usually means the three contractors are quoting three genuinely different floors. Here's how to read past the bottom-line number and compare like for like.

Here's how to read past the bottom-line number and compare like for like.
What a lowball quote usually leaves out
When a price looks too good to be true, the savings are almost always hiding in the parts you can't see once the floor is finished. The most common omissions are the prep method (acid etching instead of mechanical grinding), the number of coats, and whether there's a dedicated topcoat at all. A cheaper bid may also assume your concrete is in perfect shape — no crack repair, no oil-stain remediation, no moisture testing — and treat anything it finds as a change order later. It's worth asking directly whether the quote is a complete single-coat system or a multi-layer build, because those are not the same product even if both are called 'epoxy.'
How to read a quote line by line
A quote you can actually trust tells you four things: how the slab will be prepared, how many coats go down and of what, whether decorative flake or a topcoat is included, and how cracks and moisture will be handled if they show up. Diamond grinding or shot blasting signals real surface profiling; 'acid wash' or 'clean and coat' on a garage that sees vehicles is a yellow flag. Look for a named topcoat — a polyaspartic or urethane clear coat is what gives the floor its abrasion and UV resistance. If two quotes are far apart, line them up side by side and you'll usually find the expensive one is buying grinding, an extra coat, and a topcoat the cheap one skipped.
The questions that reveal the real scope
You don't need to be a coatings expert to level the playing field — you just need to ask a few pointed questions and give every bidder the same ones. Ask how they'll profile the concrete and why they chose that method. Ask whether they moisture-test the slab and what happens if it reads high. Ask what the full cure schedule is before you can walk on it and before you can park on it, since a rushed timeline sometimes means a thinner, faster system. Finally, ask what warranty covers and what voids it. The answers turn three mystery numbers into an apples-to-apples comparison, and the contractor who answers plainly is usually the one who has done the homework.
