Concrete Repair vs. Replacement
Not every cracked slab needs to be torn out. Small cracks and surface wear can often be repaired or resurfaced. Widespread cracking, heaving or crumbling usually means replacement.
Repair options
| Option | Good for | Limits |
|---|---|---|
| Crack filling | Hairline and small cracks | Cosmetic; cracks may reappear |
| Patching | Small holes and chipped edges | Patches may not match in color |
| Resurfacing (overlay) | Surface flaking (spalling) and worn finishes on a sound slab | Will not fix a slab that is moving or broken |
| Leveling | Sunken sections | See concrete leveling vs. replacement |
Signs replacement is the better choice
- Cracks wider than about a quarter inch or many interconnected cracks.
- Sections that have heaved or tilted from tree roots or frost.
- Crumbling throughout, not just at the surface.
- Poor drainage that sends water toward the house; replacement lets you fix the slope.
Removing an old concrete patio typically costs $550–$1,700, according to our deck and patio cost guide.
Getting quotes
- Ask what is causing the damage (water, roots, poor base) and how the repair addresses it.
- For replacement, ask about base depth, reinforcement, control joints and slope.
- Ask how long before you can walk or drive on new concrete.
