Concrete Driveway Repair Cost: Cracks, Resurfacing and Leveling

Quick reference: the terms that change the price

Four terms explain most of the gap between two quotes for the same job.

Cost by problem

The same crack can be a $150 cosmetic fix or part of a $2,300 resurfacing job, depending on whether the slab is moving and how much of the surface is damaged. The diagnosis is the quote.

Repair or replace? The question that decides the budget

Repair makes sense when the slab is structurally sound and the problems are at the surface. Replace when the base has failed, the slab is broken into several moving pieces, or the drainage cannot be fixed in place.

A useful rule: repair the surface, replace the base. If the slab moves as one piece, lifting or resurfacing can work. If it moves in several pieces, the base has failed and any new surface fails with it. That is why a repair quote that ignores the base is not a real quote.

Mudjacking and foam lifting: what you get for the money

Mudjacking costs about $3 to $6 per square foot, or roughly $700 to $2,100 for a typical sunken section, and a whole driveway can run $3,000 to $6,000. Most companies have a minimum charge of $400 to $800, so lifting one small square costs close to lifting three.

Polyurethane foam does the same job for $5 to $25 per square foot. It is lighter, cures faster and is less messy, which matters under interior floors or where soil is weak. For a simple driveway panel, slurry is often enough; for a garage floor or a pool deck, the lighter material can be worth the premium.

What a repair cannot fix

Repair will not fix a settling foundation, a broken sewer line or a drainage problem that keeps water under the slab. If the house is dropping rather than the driveway, that is underpinning and a structural engineer, not a concrete repair crew.

If a trip hazard is the only problem, grinding a raised edge costs about $100 to $300 and takes under an hour. It solves the safety issue without lifting anything, and it is often the cheapest correct answer.

A worked example: patching vs resurfacing a 24 by 24 driveway

A 24 by 24 driveway is 576 square feet. Patching cracks and small imperfections at $1.75 to $2 per square foot is roughly $1,000 to $1,150. Resurfacing the same area at $2.50 to $4 per square foot is $1,440 to $2,300. Lifting a sunken section at $3 to $6 per square foot is about $1,700 to $3,500 for the same area, though lifting is usually priced per section rather than for the whole driveway.

The numbers explain why the same driveway can get quotes that differ by a factor of two: they are not the same job. Patching is maintenance; resurfacing is a cosmetic rebuild; lifting addresses movement.

Five repair mistakes that shorten the fix

• Filling cracks without routing and cleaning them, so the filler fails within a season.
• Resurfacing over a slab that is still moving or wet.
• Skipping the base repair when a section has settled.
• Using the wrong product in cold or wet weather.
• Choosing the cheapest quote without knowing which problem it solves.

The fix usually lasts as long as the preparation behind it. A repair that starts with cleaning, routing and a diagnosis lasts years longer than a fast cosmetic patch.

When to call an engineer instead of a repair crew

Concrete repair is the right trade for flatwork. It is the wrong trade when the house is moving. Call an engineer if interior doors stick, if cracks in the foundation wall widen, or if the floor inside slopes with the driveway outside.

Foundation repair starts with a diagnosis: an engineer report is $450 to $600 in the published data, and underpinning runs $1,250 to $3,100 per pier. Paying for a diagnosis is cheaper than paying for the wrong repair.

Crack types and what they mean

Not every crack is a repair emergency. Hairline cracks are usually cosmetic and can be sealed. Cracks that follow a straight line and stay closed are often control joints doing their job. Cracks that are wide, uneven, or let one side sit higher than the other point to movement and need a diagnosis, not a filler.

Map the cracks before calling a contractor: photograph them with a ruler, note whether they have widened since last year, and check for water staining. That record is what a good contractor needs to quote the right repair.

Sealing: when it helps and when it does not

Sealing costs $0.25 to $0.50 per square foot and slows water, salt and staining. It does not fix cracks, stop a moving slab, or restore a spalled surface. On a sound slab, sealing every few years is cheap maintenance. On a failing slab, it is a cosmetic coat over a structural problem.

Seal after curing, not immediately after the pour, and never over a wet slab. A sealer applied too early traps moisture and can cause a white haze or delamination.

How long a repair lasts, and the maintenance that follows

A patch in a stable slab can last years. A resurfacing over a sound base can last a decade or more with sealing. A repair over a moving slab fails within a season or two, no matter how good the material.

After any repair, keep the joints sealed, keep water draining away and avoid de-icing salt on new patches for the first winter. Maintenance is small; neglect is what turns a $200 repair into a $2,000 replacement.

Repair versus replacement: the money view

A repair is cheaper this year; replacement is often cheaper over twenty. Patching a crack that returns every season costs more than the first quote suggested. If the slab has failed in several places or the base is moving, replacement is the lower total cost even though the invoice is larger.

The decision line is usually around half the replacement price: if a repair costs more than about half a replacement and the slab has multiple failures, replace it.

Choosing a repair contractor

Ask what problem the repair solves, which product is used, how the crack or area is prepared, and what the warranty covers. A crew that quotes without looking at the drainage is guessing.

Ask for photos of similar repairs after a winter, not just fresh work. Concrete repairs show their quality in the second year.

Resurfacing, overlay or replacement

Each step up the table fixes more but costs more. The mistake is jumping to replacement when patching works, or patching when the base has failed.

What repair day looks like

Most repairs are one day: clean and prepare the area, route and fill cracks, apply the repair material, then seal or cure. Traffic restrictions depend on the product, usually 24 hours for foot traffic and longer for vehicles. Resurfacing takes longer to cure than patching.

Ask for the product cure time and the weather limits before the crew starts, and keep vehicles off until the stated time.

How to brief a repair contractor

Describe the problem with photos and a timeline: when it appeared, whether it has grown, and what the surface looks like after rain. State what you want: a safety fix, a cosmetic improvement or a permanent repair.

Ask for the diagnosis in writing, the product names and the warranty. The diagnosis is what separates a repair from a patch.

Seasonal and weather limits for repairs

Sealers and resurfacing products need dry conditions and moderate temperatures. Patching can be done in a wider range, which makes it the practical winter option. Resurfacing should wait for a dry, mild window.

Ask for the product temperature range before scheduling and plan the cure time around your parking needs.

Long-term maintenance after a repair

After a repair, keep joints sealed, keep water moving away and avoid de-icing salt on new patches for the first winter. A repaired slab still needs the same drainage and sealing as a new one.

Check the repair in spring. A patch that has lifted or cracked by the first thaw points to a base or drainage problem that was not fixed.

When repair is not worth it

Repair stops being worth it when the slab has failed in several places, when the base is moving, or when the repair price approaches half the replacement price. At that point, patching is buying time, not solving the problem.

Replacement quotes should include tear-out and disposal. If they do not, add that to the comparison before deciding.

A step-by-step repair decision guide

Step 1: describe the problem precisely. Photograph every crack, pothole and settled area with a ruler or coin for scale. Note when each appeared and whether water stands on the surface after rain. A written description with photos gets better quotes than "my driveway is cracked".

Step 2: decide what the slab is doing. A stable slab has cracks that have not changed shape, a surface that may be worn, and no water pooling against the house. A moving slab has widening cracks, uneven sections, or doors that stick near the driveway. Stable slabs are repair candidates; moving slabs need a base or drainage diagnosis first.

Step 3: pick the smallest correct fix. For a stable slab, sealing, patching or resurfacing in that order, depending on how much surface is damaged. For a sunken but sound slab, lifting. For a failed base or multiple broken sections, replacement. Doing the smallest correct fix keeps money available for the real problem.

Step 4: get two quotes with the diagnosis in writing. A quote should name the problem, the method and the product. If two contractors disagree about the cause, that disagreement is valuable: it tells you a diagnosis is missing.

Step 5: check the base and drainage plan. A repair without a plan for the water that caused it will fail again. Grading, downspout extensions and joint sealing belong in the scope where relevant.

Step 6: schedule the weather window. Sealers and resurfacing need dry, mild conditions; patching is more tolerant. Plan the cure time around parking and access.

Step 7: keep the record. Photos, product names and the warranty go into the same folder as the house documents. A future owner, insurer or repairer will ask for them.

Most driveway repair regret comes from skipping steps 1 and 2 and going straight to a price. The diagnosis is the cheap part of the job and the one that decides the rest.

How to compare repair quotes

Ask what problem the quote is solving, how much area it covers, what material is used, and whether it includes cleaning, crack routing and sealing. A crack filled without routing and cleaning will fail; a resurfacing over a wet slab will delaminate.

Then compare the diagnosis, not just the price. Two quotes for the same crack can differ tenfold because one is patching and the other is resurfacing a section.

Season and weather matter for repairs

Most repair products need dry conditions and moderate temperatures. Sealer and resurfacing in cold or wet weather fails early. If the repair is urgent, patching can be done in a wider range of conditions than resurfacing, and a temporary fix may be the right call until spring.

Ask what the weather window is for the product the contractor plans to use, and put the cure time and traffic restrictions in the quote.

What this guide does not cover

Some jobs depend on things a national range cannot see. These are the ones where you need a local quote or an engineer.

• Structural foundation movement, which needs an engineer and underpinning.
• Sewer, drainage or utility problems under the slab.
• Full-depth slab replacement, priced as a replacement not a repair.
• Permit and inspection requirements that vary by city.
• Engineered repair designs for commercial or unusual loads.
