Three quotes for the same Colorado Springs driveway, and the numbers are nowhere near each other. Nothing on any of them explains why.
The quotes are not for the same work. They look that way because the parts that differ all happen before anything visible goes down.
Here is how to tell them apart. These questions work on us too, and that is the point.
1. Are you grinding or etching?
This is the one question that sorts quotes fastest.
Concrete has to be mechanically opened before a coating will bond to it. Diamond grinding does that. Acid etching, where a wash is poured on and rinsed off, does not open it anywhere near enough.
Grinding takes equipment, dust collection, and hours. Etching takes a jug and a hose. That difference shows up in the price, and it shows up again a year or two later when the floor comes off in sheets.
A company that grinds will say so plainly, because it is what they are charging for. A vague answer here is an answer.
2. Are you testing the slab for moisture?
On any interior floor, this should be a yes.
Concrete sits on ground, ground holds water, and water vapor moves up through the slab. Coat over a live vapor drive and the coating lifts from underneath with nothing wrong with the product at all. A calcium chloride test or a relative humidity probe tells you before, not after.
Most slabs pass and it changes nothing. The point is knowing.
3. What happens to the cracks?
If there are cracks and the quote has no repair stage, ask what the plan is. A coating goes over concrete, it does not knit it back together, and a crack that is still moving telegraphs through any finish above it.
The answer you want is that cracks get cut, cleaned, filled and ground flush before any finish. Every resurfacing job we do includes the crack repair rather than adding it later.
4. How many coats, and what are they?
“Epoxy floor” can mean one thin coat of one-part paint or a five-layer build. Both get called epoxy.
Ask for the stack: what goes down first, what goes over it, what the topcoat is. A real garage floor build is a pigmented epoxy base, a broadcast of decorative flake, and a clear polyaspartic topcoat, over a slab that was ground and repaired first.
5. Full broadcast or light?
If flake is part of it, this changes both the look and the number. Full broadcast means flake goes down until the floor is covered wall to wall and the excess is scraped back. Light broadcast scatters it for effect.
Neither is wrong. Comparing one against the other as if they are the same job is.
6. What happens at the edges?
Where the floor meets the wall is hand work. Running the coating up the stem wall or forming a proper cove takes time a roller cannot save you.
It is also where a cheap job shows first.
7. Are you licensed and insured, and can I see it?
A normal question and a fast one. Anyone who hesitates has told you something.
8. Can I see work you did three years ago?
Not last month. Anything looks good the week it goes down.
Three years in a Colorado Springs driveway or garage means it has been through mag chloride, freeze-thaw, and a couple of July afternoons with hot tires on it. That is the test.
9. What is the warranty, and what voids it?
The second half is the useful half. A long warranty whose exclusions cover everything that goes wrong is not a warranty.
10. Will you tell me if I do not need this?
The best answer a contractor can give you is that your concrete is fine and you should spend the money in a year or two.
We say it when it is true. A company that has never said it to anyone is selling, not assessing.
Comparing the quotes once you have the answers
Two quotes that answer questions 1 through 6 the same way are comparable, and then price is a fair basis for choosing.
Two that do not are not comparable at all, and the cheaper one is usually cheaper for a reason you will meet later. The why garage floor coatings peel post walks through what that reason looks like when it arrives.
If you are not sure which type of work your concrete needs before you start calling, the types of concrete coatings post sorts that out first.
FAQ
Is the cheapest quote always the worst one?
No, but it is the one to ask the most questions about. Grinding is the single most expensive part of doing it right and the easiest to leave out invisibly. If the low quote grinds, tests for moisture and repairs the cracks, it may well be a good quote. If it does not, you have found the reason.
How do I check a contractor’s work if I am not a concrete person?
Ask for addresses of jobs three or more years old and drive past them. You are not inspecting, you are looking for the obvious: peeling at the edges, patches lifting, color gone chalky. Anyone proud of their older work will hand you the list.
Does it matter if they are local?
For this work in this climate, it helps. Mag chloride, altitude UV and a hundred-plus freeze-thaw cycles a year are specific problems, and a contractor who works here every winter has seen what fails. Ask what they do differently because of the mag chloride. A real answer tells you a lot.
What if the quote has no detail on it at all?
Ask for one in writing before you decide. Prep method, number of coats, what the topcoat is, how the edges are handled, what the warranty excludes. A company that will not put that in writing has given you your answer.
Should I get three quotes?
Two or three is plenty, as long as you ask all of them the same questions. Ten quotes that you cannot compare is worse than two that you can.
