Garage floor coating cost depends on the inspected slab and the work included. Compare removal, preparation, repairs, named products, coating boundaries and return-to-use instructions before a square-foot rate. The worksheet below uses your actual quoted amounts; it does not supply a price estimate.
There is no verified Detroit Garage Coating price list yet
A project estimate needs the floor dimensions, the existing surface, repairs, access and a specified system. We have not collected a representative set of local quotes, so this page does not publish a Detroit average or advertise a starting price.
Public promotions are snapshots from individual contractors, with their own included work and terms. They are not an independent market average and should not be treated as this brand’s prices. The useful comparison is the total for the same written scope.
Measure the floor before multiplying a rate
For a rectangular floor, multiply length by width in feet. A 20 by 22 foot rectangle is 440 square feet. This is an arithmetic example, not a standard Detroit garage size or a quoted project. Measure recesses and separate areas independently. Record vertical surfaces and steps separately.
If an installer quotes a square-foot rate, ask what that rate includes and whether there is a minimum charge. Then add or confirm removal, repair and optional details. A low rate with a larger exclusion list may have a higher final price.
Use this worksheet with actual quoted amounts
No assumed rates. Enter the dollar amounts from one written proposal.
Enter your quoted costs
Avoid counting an item twice if it is already included in the main amount. Add taxes only as shown on the quote. This total is arithmetic, not an estimate from us.
Read the floor-condition allowance
Ask which cracks, damaged edges and old coatings are included. If storage hides part of the slab, identify that uncertainty. The proposal should explain how newly exposed conditions are priced and when you must approve extra work.
The technical reason for a separate preparation scope is simple: the substrate must suit the selected system. ICRI: selecting a concrete surface preparation method explains how preparation selection relates to concrete condition and the protective system. For your quote, record the specified preparation and repair work rather than rely on the phrase “professional prep.”
Compare products and details, not a layer count
| Item | What to ask each bidder |
|---|---|
| Preparation | Method, profile requirement, removal and cleaning |
| Repairs | Included defects and allowance for concealed damage |
| System | Named primer, resin layers, broadcast and topcoat |
| Boundaries | Threshold, steps, drains, vertical faces and fixed equipment |
| Return to use | Written release for people, stored items and vehicles |
| Warranty | Covered failure, exclusions and repair responsibility |
| Extra work | Unit rates or written change-order process |
Include the cost of using the room again
Decide who empties the garage, where belongings stay and where vehicles park during work. Ask whether moving a freezer or heavy tool chest is included. If the room must be available by a particular date, tell the estimator before accepting the system.
Read the installation timeline and the cold-garage scheduling guide. A quick application window and a release for your particular load are separate questions.
Before accepting a price
Keep the estimate, product list, coating boundary, any test record and written warranty together. Ask for missing items to be clarified. An honest allowance can be compared; an unspoken assumption cannot.
Describe your floor for a project discussion. Include measurements and known issues. Final contractor pricing and availability must be confirmed after the required assessment.
