| Garage | HomeGuide | Angi |
|---|---|---|
| 1-car | $1,200–$3,900 (288–392 sq ft) | $750–$3,000 (250 sq ft) |
| 2-car | $1,600–$5,800 (400–576 sq ft) | $1,500–$6,000 (500 sq ft) |

Cost per square foot
- Epoxy, professionally installed: $4–$10/sq ft per HomeGuide (about $1–$5 materials and $3–$5 labor). Angi gives a wider $2–$12 range.
- Polyurea: $5–$10/sq ft (HomeGuide).
- Polyaspartic: $5–$12/sq ft; HomeGuide puts a 2-car polyaspartic floor at about $2,000–$6,900.
Angi notes labor typically makes up roughly 33–60% of the total.
What pushes the price up
- Condition of the concrete. Patching cracks and pits runs about $25–$250 per repair area according to Angi. Badly scaled slabs may need resurfacing first, which HomeGuide estimates at $3–$7/sq ft.
- Removing an old coating. Peeling paint or failed epoxy has to come off before a new system will bond. That's extra grinding time.
- Moisture problems. A moisture-mitigating primer adds material cost.
- System choice. Full-broadcast flake, quartz, metallic, or a polyaspartic topcoat generally cost more than a single-color epoxy.
- Extras. Stem-wall coating, cove base, and moving stored items.
What can lower it
- A newer slab in good shape with no existing coating.
- A simpler finish (solid color or light flake).
- Flexible scheduling outside the busiest season.
DIY kits vs professional
Store-bought kits cost far less up front, but they're usually thinner, water-based products applied over acid-etched (rather than ground) concrete. HomeGuide estimates water-based epoxy lasts about 3–5 years, versus 10–20 years for 100% solids systems.
