Why Prep Work Is the Part Nobody Sees

This is the step contractors skip when they’re racing to finish a job cheap, and it’s the reason so many epoxy floors fail early. Cracks left unrepaired telegraph through the new coating. Low spots collect water underneath. And a slab that isn’t properly ground won’t let the epoxy bond correctly, no matter how good the topcoat is. We diamond-grind every surface to open the concrete pores, fill and level cracks with a flexible polyurea filler that moves with the slab, and moisture-test before any coating goes down. If your existing floor is failing because of bad prep work the first time around, we can also strip and re-prep it.

What’s Included

  • Free assessment of your slab’s condition
  • Diamond-grinding to open the concrete pores
  • Crack filling with flexible polyurea filler
  • Moisture testing before any coating is applied

Who Needs Crack Repair & Prep

This service isn’t just for people getting a new coating. Here’s who calls us for prep work alone:

  • Home sellers whose inspector flagged foundation or slab cracks
  • Homeowners whose old epoxy or paint coating is peeling because it was applied over bad prep
  • Anyone with a garage, patio, or basement slab that collects water in low spots
  • Businesses with damaged industrial or warehouse floors before a re-coat
  • Homeowners who just want cracks and unevenness fixed, with no coating at all

Crack Repair Questions We Hear a Lot

How do I know if my cracks are just cosmetic or a real problem?

That’s exactly why we do a free assessment before quoting anything. Hairline surface cracks are usually cosmetic, while wider cracks, cracks that run through the slab, or ones with vertical offset can point to settling. We’ll tell you honestly which one you’re dealing with.

Can you just fix the cracks without doing a full epoxy coating?

Yes. Plenty of customers just want the slab repaired and leveled with no coating on top. If you decide you want the extra protection later, our garage floor coating and other services are always available.

How long does moisture testing take, and why does it matter?

It’s built into the same visit, no extra trip required. It matters because moisture trapped under a slab is one of the most common reasons epoxy coatings fail in Charleston’s humid climate. Testing before we coat means we catch the problem instead of covering it up.

Talk to a Real Person

Yes — coating over unrepaired cracks almost always telegraphs through the new finish and can cause the coating to lift right at the crack line. Proper repair is a small upfront step compared to redoing a failed floor later.

Crack repair pricing depends on the number, size, and severity of cracks, typically ranging from a few hundred dollars for minor hairline cracks to more for structural repair work. We assess your slab and include this in your overall estimate.

Some contractors use a rigid filler that doesn’t move with the slab, which just cracks again within a season. We use a flexible filler designed to handle the natural seasonal movement of concrete, which holds up far longer.

Yes, moisture that gets into a crack and repeatedly expands and contracts with temperature changes will widen it over time. Repairing cracks early, before they grow, is usually cheaper and more effective than waiting.

You can attempt minor hairline cracks with a store-bought filler, but for cracks that will be coated with epoxy, professional repair with a flexible, coating-compatible filler gives a much more durable, seamless result.

Yes, we handle concrete crack repair and surface prep throughout the Charleston Tri-County area, both as a standalone service and as part of a full epoxy installation.

Crack filling addresses individual cracks with a flexible filler; full slab repair may involve grinding, leveling, or addressing more significant structural settling. We’ll recommend the right approach based on what we find during your estimate.

Most crack fillers cure enough to coat over within 24 hours, though we’ll confirm exact timing based on the specific product and repair scope for your project.
