Concrete Crack Repair Service in Wilmington, NC
Cracks in concrete aren't all the same — some are cosmetic, some signal movement underneath, and the repair method depends entirely on which kind you have. We assess the crack width, depth, and cause before touching it, because filling a structural crack the wrong way just masks the problem. The goal is to stop the crack from migrating and restore the surface integrity.

When to Call
When You Need Concrete Crack Repair Service
- A crack in your garage floor has grown noticeably wider over one winter
- Water is seeping through a crack in your foundation wall after heavy rain

How It Works
Our Process for Concrete Crack Repair Service
- 1
Call and Basic Triage
You describe what you're seeing and we ask a few questions — location, approximate width, any movement or heaving. This helps us bring the right materials to the estimate.
- 2
On-Site Assessment
We look at the crack in person, probe depth, check for slab movement, and look at what's around it — soil drainage, tree roots, downspout placement. Cause matters as much as the crack itself.
- 3
Surface Prep
The crack gets cleaned out with a grinder or wire brush, removing loose debris and any old filler. A dirty crack won't bond. This step takes longer than most homeowners expect.
- 4
Repair Application
Depending on crack type, we use polyurethane injection, epoxy, or a routed-and-sealed method. Structural cracks get different treatment than shrinkage cracks — we don't use one product for everything.
- 5
Cure and Inspection
We let the repair cure properly before calling it done, then walk you through what we did and what to watch for. Some repairs need a second pass after full cure.
What's included
- Full visual and physical assessment of crack cause and severity
- Surface grinding and debris removal before any filler is applied
- Appropriate filler material matched to crack type and location
- Labor for the complete repair from prep through finish
- Walkthrough explaining what was done and what to monitor going forward
What's not included
- Repairs to underlying soil or drainage issues causing the cracking
- Cosmetic color-matching to aged or stained existing concrete surfaces
- Structural engineering assessments for foundation movement concerns
Real Situations
Common Scenarios in Wilmington
A homeowner in Midtown Wilmington has a garage floor with three parallel cracks that appeared after a dry summer followed by heavy fall rain.
We assess whether the cracks are from normal shrinkage or slab movement. If there's no differential settling, we clean and route the cracks and fill them with a semi-rigid polyurethane that handles minor flex. We explain that some surface staining from the old cracks will remain.
A family near Wrightsville Beach notices a crack along the base of their exterior concrete steps that gets a little wider every year.
We check whether the steps have separated from the house foundation or are just settling independently. That determines if epoxy injection is appropriate or if the steps need to be addressed with mudjacking first. We won't fill a crack that's actively moving — it won't hold.
A homeowner in Ogden calls about a crack in their back patio that water runs into and then comes up under the door threshold.
We trace the drainage path and fill the crack with a waterproof sealant rated for horizontal surfaces. We also look at whether the patio slope is directing water toward the house, since fixing the crack alone may not solve the water intrusion problem.
Wilmington Context
Why this matters in Wilmington
Wilmington's sandy, expansive soil shifts with the wet-dry cycles that come with coastal weather. Slabs poured in the 1980s and 1990s — common in neighborhoods like Masonboro and Carolina Place — are at the age where shrinkage cracks have had decades to grow. Salt air also degrades sealants faster here than inland, so cracks that were sealed once may be open again.
Straight Talk
About pricing & scope
Crack repair cost varies based on total linear footage, crack depth, and which method is appropriate. Hairline shrinkage cracks cost less to address than wide structural cracks needing injection. We sometimes find mid-job that a crack goes deeper than it appeared on the surface — we'll tell you before we proceed further.
