How do I know if my garage floor needs a new install or just a repair?

If the concrete has never been coated, you need a new install. If there's an existing epoxy or polyaspartic coating that's failing in spots but mostly intact, a repair or recoat is usually enough.

Is it cheaper to repair than to install new?

Generally yes, because repair work covers less surface area and skips some of the prep steps a full new install requires.

Can a repair be done on top of an old coating that was applied poorly?

Not usually. If the original prep was bad, most installers will recommend grinding it all off and starting over rather than repairing on top of a weak bond.

New epoxy install vs. repairing an existing garage floor

Garage floors usually fall into one of two jobs: a brand new coating over bare or previously uncoated concrete, or a repair/recoat of a system that's already failing. The prep, materials, and timeline differ enough that it's worth figuring out which one you actually need before calling around for quotes.

New install: bare concrete or an old paint/sealer that needs full removal, followed by grinding or shot-blasting and a multi-coat epoxy or polyaspartic system
Repair/recoat: an existing epoxy or polyaspartic floor with peeling, chipping, or wear in traffic lanes, needing patch work or a full recoat over sound existing material
Signs you need a repair rather than a new install: coating is lifting at the edges, hot tire marks, isolated cracking
Signs you need a new install: floor was never coated, or old coating has failed across most of the surface

Providers on this list quote both, so describing your floor's current condition up front gets you a more accurate estimate.

What it costs

A full new install involves more grinding, more coats, and more material, so it typically costs more than a repair or recoat of an already-prepped floor. Getting an accurate quote depends on describing the current state honestly: bare concrete, lightly worn coating, or heavily failed coating all lead to different scopes of work.
