Miami Estimate Guide
A Miami garage floor estimate, decoded line by line
A garage floor coating estimate Miami homeowners can trust is itemized: prep, moisture, system, and topcoat as separate lines. This page is the decoder — what each line of a real estimate should say, what has to happen in your garage before any honest number exists, and how a request on this site turns into one installer's written estimate instead of an auction of your phone number.
What a real estimate contains, line by line
Prep, named
Diamond grinding (or shot blasting) stated as the method, with crack and joint repair as its own line. “Prep included” with no method named is where cheap quotes hide an acid etch.
Moisture, in writing
Your slab's actual reading, and the mitigation line — roughly $1.50–$3.00 per sq ft — if it tests wet. In Miami-Dade this line decides whether the floor survives its first wet season; an estimate written before the reading cannot contain it.
The system, by layer
Base coat chemistry and build, the flake broadcast, and the topcoat — each named. A full polyaspartic system and an epoxy-base hybrid are different builds at different prices; the estimate should say which one you are buying.
The rest of the job, priced
Removal of a failed coating as its own line (roughly $1.50–$3.00 per sq ft), stem walls, steps, and edges, cure and return-to-service times, and the warranty — including whether a prep failure is covered.
Before the number: the measure and the reading
Every line above depends on two things no phone call can supply: the garage measured in person, and a moisture reading taken from your slab. Moisture is the Miami variable — the county's water table pushes vapor up through concrete, and a coating priced without the reading is priced without the fact that decides the system build. That is why a sight-unseen firm price is a guess wearing a signature. Planning numbers are fine before the visit — the Miami cost guide and the cost calculator exist for exactly that — but the estimate itself is written after someone stands in your garage.
How the match works — and what a qualified request requires
Dade Garage Floors is a matching service, not an installer. A request goes to one participating Miami-Dade installer — one introduction, not a bidding war — who books the visit, takes the reading, and writes the itemized estimate. A qualified request is a homeowner (or decision-maker) with a real coating project — a new system, a replacement, or removal plus recoating — who wants that on-site estimate within the next 90 days. Repair-only, DIY, and product questions are answered honestly and routed differently; nobody buys them as leads. Timing questions — how long the estimate stays valid, whether the visit is charged — are answered by the installer's stated policy, in writing, before the visit is booked.
Miami estimate questions
What should a garage floor coating estimate Miami homeowners receive actually contain?
Separate, named lines: the prep method (diamond grinding, stated — not "prep included"), your slab's moisture reading and the mitigation line if it tests wet, the system build by layer (base, flake, topcoat, named products or chemistry), crack and joint repair, removal of any old coating as its own line, stem walls and steps if they are coated, cure and return-to-service times, and the warranty terms. One lump sum with none of that is not an estimate — it is a teaser.
Why won't a good installer give me a firm price from photos?
Because the three things that set the price are invisible in photos: the slab's moisture level, the hardness and condition of the concrete under the surface, and what is actually bonded to it now. A firm number given sight-unseen is either padded against surprises or headed for a mid-job revision. A planning range from photos is honest; a contract price needs the visit.
How long is a Miami garage floor estimate valid?
Practices vary by installer — many written estimates carry a stated validity window, commonly a few weeks, after which material pricing is rechecked. What matters is that the window is printed on the estimate you hold. If it is not stated, ask before you compare it against fresher quotes.
Does the estimate visit cost anything?
That depends on the installer. Some fold the measure and moisture reading into the project, others charge a visit or testing fee that is credited on signing. Either model can be fair — what is not fair is discovering it afterward. Your matched installer states their policy up front, before the visit is booked.
What makes a request a qualified one on this site?
You own the home (or decide for it), the garage is a coating project — new system, replacement of a failed one, or removal plus recoating — and you want an on-site estimate within the next 90 days. Repair-only questions, DIY advice, and product-only requests are answered honestly and routed differently; they are never sold as leads.
