Concrete Repair vs. Replacement: How to Decide
Not every crack means you need a new slab. Here’s how to tell whether repair or full replacement makes sense.
When repair is usually enough
- Hairline or surface cracks that aren’t widening.
- Minor spalling or pitting on the surface.
- A few small, isolated cracks in otherwise sound concrete.
- Slabs that have settled slightly (often fixable with mudjacking/foam leveling).
When replacement is the better call
- Deep, wide, or rapidly spreading cracks.
- Significant heaving, sinking, or unevenness.
- Widespread crumbling or large sections of damage.
- Concrete near or past its lifespan (driveways often last 25–30+ years).
Cost trade-off
Repairs are far cheaper short-term, but pouring good money into a failing slab adds up. If repair costs approach roughly half the price of replacement — or the damage is structural — replacement is usually the smarter long-term investment.
Frequently asked questions
Can cracked concrete be repaired instead of replaced?
Often yes — stable, minor cracks can be filled and sealed. Structural or spreading damage usually warrants replacement.
