Expansion Joint Repair Service in Wilmington, NC
Expansion joint repair involves replacing the compressible filler and sealant in joints designed to absorb movement between concrete sections or between concrete and another structure. These joints are not the same as control joints — they handle larger movement and are often found where a slab meets a building foundation, bridge, or curb. When expansion joint material breaks down, the joint closes under heat expansion and the concrete has nowhere to go but up or sideways.

When to Call
When You Need Expansion Joint Repair Service
- Your concrete patio is buckling where it meets your Wilmington home's foundation

How It Works
Our Process for Expansion Joint Repair Service
- 1
Joint Evaluation
We confirm the joint type, measure total movement gap, and check if adjacent concrete has already been damaged.
- 2
Old Material Removal
Deteriorated foam, rubber, or sealant is fully extracted — leaving remnants causes the new install to fail.
- 3
Filler Installation
New compressible backer is sized to the joint and set at the correct depth for the sealant above it.
- 4
Sealant Finish
A flexible, UV-stable sealant is tooled over the backer to complete the weathertight seal.
Wilmington Context
Why this matters in Wilmington
Expansion joints in Wilmington take real thermal stress — summer slab temperatures here can exceed 140 degrees on exposed concrete. Standard foam filler compresses permanently at those temperatures, which is why so many older Wilmington slabs show buckling at what should be a functioning joint.
Straight Talk
About pricing & scope
Cost depends on joint depth, total linear footage, and whether the adjacent concrete needs edge repair before the new material will bond properly. Joints near water features or pool decks often require a different sealant chemistry entirely.
