Most garage floor coating failures don't come from bad chemistry — they come from bad contractors. The same Big Box epoxy that peels in 18 months in one driveway can last 20 years on another, and the difference is almost always the crew that installed it. Here's how Nashville homeowners should vet contractors before signing anything.
Ask How They Prep the Slab
If a contractor doesn't lead with concrete grinding, walk away. Mechanical grinding with a diamond-tooled rig is the industry standard for residential and commercial floor coatings — acid-etching is for hobbyists. Any pro you hire should describe the grind, the moisture test, and the crack-repair process before they ever mention color.
Verify the Materials They Use
There's a huge gap between '100% solids epoxy with a polyaspartic topcoat' and 'water-based epoxy with a clear coat from the home center.' Ask for product data sheets, brand names, and solids content. Pros are happy to provide them — closers won't.
Check License, Insurance, and Reviews
Tennessee doesn't require a specific epoxy-installer license, but legitimate contractors carry general liability and workers' compensation. Ask for a certificate of insurance. Then check Google reviews, focusing on installs that are 2+ years old — that's where peeling shows up.
Read the Written Quote Carefully
A real garage floor coating quote in Nashville lists: square footage, prep method, base coat product, flake brand and coverage, topcoat product, crack repair scope, and a clear timeline. A one-line quote that just says 'epoxy garage floor — $X' is a red flag.
Beware of High-Pressure Sales
If a contractor offers a 'today-only' discount or asks for a large deposit at the door, walk away. Pros price honestly and let you take time to decide. We've never had to discount our way into a job — and we never will.
