How to choose a garage floor coating contractor in Charleston.
The difference between a floor that lasts 20 years and one that peels in two usually comes down to prep and the fine print — not the color. Here’s what to ask a Charleston contractor before you sign.
Prep is everything
Ask exactly how they prep the slab. Diamond grinding opens the concrete so the coating bonds mechanically; an acid etch (or no prep) is the #1 reason coatings lift and peel. If a Charleston bid is far cheaper than the rest, skipped prep is usually why — and you’ll pay again to grind off the failure and redo it.
Warranty red flags
- Does the warranty cover both materials and labor? Many “lifetime” warranties quietly exclude one or both.
- Are there moisture exclusions (MVER thresholds, Tramex readings) buried in the terms? Those are often escape clauses to deny a claim.
- Do they apply a moisture-mitigating primer on every job, or only after they “find” moisture on install day and upcharge?
- Can they produce technical data sheets for the products they’re using?
- Are they licensed, insured, and local, with Charleston-area references you can check?
What matters locally
The Lowcountry is relentless on concrete. Coastal humidity keeps slabs damp, salt air attacks weak coatings, and many Charleston-area homes sit low against a high water table. Moisture from below is the first thing to solve here — without proper prep and a moisture-tolerant finish, even a good-looking coating blisters in the coastal air. From historic-district properties to newer raised builds, the common thread is humidity, so a slab read and moisture management come before anything decorative.
That’s why moisture control and the right prep aren’t optional add-ons in the Lowcountry — they’re the job.
