When to Level Concrete vs. Replace It

Should You Level Your Concrete or Replace It?

Leveling costs 50-75% less than replacement and typically takes one day instead of a week. But some slabs need replacement. Here's how to decide.

When Leveling Is the Right Call

Concrete leveling works well when:

• The slab has settled but is still structurally sound
• Cracks are minor (hairline to moderate) and primarily caused by settlement
• The slab has not settled more than a few inches
• The concrete surface is in reasonable condition
• You want to save money compared to full replacement
• You need a faster solution with less disruption

When Replacement Is Necessary

Full replacement may be the better option when:

• The concrete is severely cracked or broken into multiple pieces
• The slab has settled more than 4 to 6 inches
• The concrete surface is badly deteriorated, spalled, or eroded
• There are significant structural issues with the subgrade
• The concrete is very old and near the end of its useful life
• You want to change the size, shape, or finish of the slab

Cost Comparison

Concrete leveling typically costs 50 to 75% less than full replacement. For a typical driveway slab, leveling might cost $500 to $2,000, while replacement could run $3,000 to $8,000 or more. For a single sidewalk section, leveling might cost $200 to $500 versus $500 to $1,500 for replacement.

The Middle Ground

In some cases, a hybrid approach works. Level most of your concrete and replace only the worst sections. A qualified contractor can help you identify which slabs are good candidates for leveling and which should be replaced.

Getting Professional Advice

The most important step is having a knowledgeable contractor evaluate your concrete in person. Look for a company that offers both leveling and replacement services, since they are more likely to give you an honest recommendation rather than pushing the only service they offer.
