Labor-heavy projects (with high labor costs) benefit most from getting multiple contractor bids. You can save on materials-heavy projects by sourcing materials yourself at contractor pricing.
Contractor Quote Worksheet for Epoxy Garage Floor Coating
Use this checklist when comparing bids. The cheapest quote is not always the lowest final cost; the bid that defines scope, allowances, permits, cleanup, and change-order rules usually gives the cleaner budget.
| Bid line | What to ask | Why it matters |
|---|---|---|
| Scope definition | Confirm what is included in the epoxy garage floor coating base bid and what is priced as an allowance or option. | Vague scope turns into change orders after demolition or material selection. |
| Labor assumptions | Labor is about 55% of the mid-range budget. Ask whether demo, prep, cleanup, disposal, and final punch-list time are included. | A low bid may exclude prep work, disposal, or return trips. |
| Material allowances | Materials are about 45% of the budget. Get brand, grade, finish, and quantity assumptions in writing. | Allowance bids look cheap until fixtures, finishes, or delivery fees are upgraded. |
| Permit and inspection plan | Confirm whether your city treats this as permit-exempt or requires a trade, zoning, or HOA approval. | Permit gaps can delay final payment, insurance claims, or home resale. |
| Timeline and disruption | The normal timeline is 2-3 days. Ask what happens if materials arrive late or hidden conditions are discovered. | A fast verbal timeline without milestones is hard to enforce. |

Garage Floor Coating Prep Audit
Epoxy and polyaspartic floors fail when prep is rushed. Compare quotes by surface preparation, moisture handling, product system, thickness, and return-to-service timing.
Scope checks
- 1Ask whether the slab will be diamond-ground, crack-repaired, moisture-checked, vacuumed, primed, broadcast, and topcoated.
- 2Confirm the product system, flake coverage, anti-slip additive, UV resistance, hot-tire pickup warranty, and cure schedule.
- 3Define who moves items, protects walls, ventilates the garage, and handles edge detail at doors and steps.
Quote traps
- Acid-etch-only prep on a slab that needs mechanical grinding.
- No moisture or vapor discussion.
- A one-day promise without explaining cure time and product chemistry.
Proof to collect
- ✓Prep photos after grinding and crack repair.
- ✓Product data sheet or coating system name.
- ✓Written cure, cleaning, and warranty instructions.
