Concrete is tough, but it doesn’t last forever. Cracks, sinking slabs, and crumbling edges can hurt curb appeal, create trip hazards, and lead to costly damage if ignored. A good concrete repair contractor can restore safety and appearance without a full replacement.
Below is a clear guide to help you spot problems early, understand your options, and hire a contractor you can trust.
Common Signs You Need Concrete Repair
Watch for these issues around your home:
- Cracks in driveways and walkways
Hairline cracks are common, but wider or growing cracks, or cracks that are uneven (one side higher than the other), should be checked.
- Uneven or sunken slabs
If part of your driveway, patio, or sidewalk has dropped or lifted, it can cause pooling water and trip hazards.
- Crumbling or flaking surfaces (spalling)
The top layer breaks away in chips or flakes, often from freeze-thaw cycles, de-icing salts, or poor installation.
- Pitting and holes
Small pits, exposed aggregate, or holes can collect water and worsen over time.
- Water draining toward your home
Slabs that tilt toward your foundation, garage, or basement can push water where you don’t want it.
If you see one or more of these, it’s worth getting a professional opinion before the damage spreads.
Types of Concrete Repair & What to Expect
Not all problems need a full tear-out. Here are common repair methods and what typically happens during the project.
Crack filling and sealing
Best for: Hairline to moderate cracks that are stable.
What pros do:
- Clean out dirt, debris, and loose concrete
- Fill cracks with a flexible or rigid repair material
- Seal the area to keep out water and ice
What you can expect:
- Usually a quick, lower-cost repair
- Short cure time; you may need to stay off the area for a day or so
Surface patching and resurfacing
Best for: Spalling, pitting, and cosmetic damage when the slab is still structurally sound.
What pros do:
- Grind or clean the surface
- Repair deep pits or localized damage
- Apply a thin overlay or resurfacer for a smoother, fresh-looking finish
What you can expect:
- A noticeable improvement in appearance
- Options for light texturing or slip resistance
- Curing time before driving or placing heavy items back on the surface
Slab lifting (mudjacking or foam lifting)
Best for: Sunken driveways, walkways, garage floors, and patios that are otherwise in good shape.
What pros do:
- Drill small holes in the slab
- Pump in a mixture (slurry or foam) to raise the slab back into position
- Patch the holes and clean the work area
What you can expect:
- Often faster and more affordable than full replacement
- Minimal disruption to landscaping
- Limited downtime; many slabs can be used again soon after lifting
Full slab replacement
Best for: Severely cracked, broken, or poorly installed concrete where repairs won’t last.
What pros do:
- Demolish and remove old concrete
- Prepare and compact the base properly
- Install new forms, reinforcement, and pour new concrete
- Finish, cure, and seal the new slab
What you can expect:
- Higher cost and longer timeline than repair
- Several days to weeks of curing before full use, especially for driveways
How to Evaluate and Hire a Concrete Repair Contractor
Concrete repair is part skill, part judgment. A good contractor will explain options, not push the most expensive one.
Questions to ask before you hire
- What repair method do you recommend and why?
They should explain the pros and cons of each option for your specific slab.
- How long should this repair realistically last?
No one can promise forever, but they should set honest expectations.
- Are you licensed and insured for this type of work?
This protects you if something goes wrong on site.
- Can I see recent local projects or reviews?
Photos and references help show the quality of their work.
- What is included in your quote?
Ask about surface prep, disposal of old concrete, sealers, and cleanup so there are no surprises.
Comparing quotes the smart way
When you request estimates from multiple pros:
- Share the same details with each contractor (photos, measurements, age of the slab, problem areas)
- Look beyond price – consider methods, materials, warranties, and timeline
- Be wary of quotes far below the others – that can signal shortcuts in prep, base, or reinforcement

Preparing for Your Concrete Repair Project
A little planning can make the job smoother and faster.
Before work starts
- Clear the work area – move vehicles, planters, furniture, and toys
- Plan parking and access – especially for driveway or garage work
- Discuss noise and hours with your contractor, and let neighbors know if work will be loud
- Confirm curing times – when you can walk, park, or place heavy items back on the surface
During and after the repair
- Stay available for quick decisions about small changes or add-ons
- Follow care instructions – such as avoiding de-icing salts on new concrete the first winter
- Schedule follow-up sealing if recommended, to extend the life of the repair
When to Repair vs. Replace
Use these simple guidelines:
- Repair is usually enough if:
- Cracks are limited and not rapidly spreading - The slab is mostly level and solid - Damage is mainly surface-level
- Replace may be better if:
- Large sections are broken or heaving - The base beneath the slab has failed - Past repairs keep failing or look patchy
A trusted concrete repair pro can walk you through both options and help you choose what makes the most sense for your home and budget.
