Let’s talk about it—Florida concrete loves to crack. But that doesn’t always mean disaster.

Concrete naturally expands and contracts with heat. So small cracks? Totally normal. But how do you know when a crack’s just a cosmetic issue—or a sign of something serious?

Tip #1: Hairline Cracks? Relax.

Thin cracks (think: less than 1/8 inch) are usually no big deal. Especially in driveways, patios, or sidewalks. Just keep an eye on them.

Tip #2: Cracks You Can Fit a Dime In? Watch Out.

Wider or deeper cracks, especially those that shift in height between sides, could point to a structural problem—like soil settling, erosion, or even sinkhole activity in some parts of Florida.

Tip #3: Diagonal Wall Cracks Inside? Call a Pro.

If you see diagonal cracks above doors or windows inside your house, or if doors won’t close right anymore—that’s a red flag. Your foundation might be shifting.

A story: One homeowner called me about a crack in their carport. We checked it out and realized water from the gutter had been draining there for years, softening the soil underneath. The fix? Reroute the gutter, recompact the soil, and patch the concrete. No more crack.

Tip #4: Seal and Maintain

Even harmless cracks should be sealed to prevent water intrusion. Florida’s moisture can work its way in, freeze (rare, but it happens), or lead to mold and mildew buildup underneath.

Bottom line: not all cracks are a crisis. But don’t ignore the ones that grow, shift, or keep coming back. And when in doubt, call someone to check it out.
