Quick answer
Garage floor repair cost depends on diagnosis and finish goals:
garage floor repair cost =
prep and diagnosis
+ repair method
+ moisture, coating prep, cleanup, and warranty terms
If the floor will receive epoxy, the repair quote must include prep quality, moisture checks, and whether cracks may telegraph through the coating.

FAQ
Can I epoxy over repaired concrete?
Sometimes, but the slab must be prepared correctly. Ask the coating contractor whether repairs will remain visible or affect warranty.
Is garage floor lifting cheaper than replacement?
It can be when the slab is intact and settled. Broken, thin, or badly spalled concrete may not be a good lifting candidate.
What should I photograph?
Photograph cracks, spalls, floor drains, garage door edges, vehicle paths, and any water stains before asking for bids.
