Your concrete walkway is showing its age with spreading cracks, and you are torn between attempting repairs yourself or hiring a professional. Making the right choice depends on understanding the type and severity of the damage you’re facing.
In this detailed guide to concrete crack repair, you will find how to assess the damage, learn which repairs you can handle yourself, and understand when professional concrete repair services become necessary for your walkway’s longevity.
Take a closer look at your concrete walkway to spot these common crack types. Understanding the type of crack will help you pick the right repair method:
These tiny surface cracks are usually less than 1/8 inch wide. While they might look concerning, these narrow cracks often don’t affect your walkway structural integrity. They typically form during the concrete drying process. You can easily fix these using a concrete patching compound.
Measuring between 1/8 to 1/4 inch wide, these cracks need quick attention. These cracks in concrete often result from slight ground settlement or seasonal temperature changes. You will want to repair these using a concrete patch or specialized crack repair products to prevent them from growing larger.
Any crack wider than 1/4 inch or extending deep into the concrete slab needs serious attention. These cracks can let water seep underneath your walkway, causing more damage. For these bigger cracks, you might need to use a combination of backer rod and self-leveling caulk for an effective repair.
These are the most severe, often showing signs of heave or uneven surfaces. Tree roots, major ground settling, or freezing and thawing cycles usually cause these problems. When you see this type of cracked concrete, you might need to consider removing and replacing the damaged concrete sections.
Remember, the sooner you tackle these cracks, the easier and cheaper your concrete crack repair will be. If you’re unsure about the type of crack you are dealing with, its smart to consult a professional for an accurate assessment of your concrete problems.
If you are facing hairline or moderate cracks in your concrete walkway, dont worry – these are often manageable through simple home improvement fixes. Surface cracks and narrow cracks typically respond well to DIY repair methods.
For hairline cracks measuring less than 1/8 inch, a concrete patching compound works great. You’ll need to clean the area thoroughly before applying any repair materials to ensure the patch bonds properly with the existing concrete.
Moderate cracks between 1/8 to 1/4 inch need a bit more attention. For these, you will want to use a concrete mix or specialized crack repair products. These materials are specifically designed for cracks of this size and create a uniform repair that blends with your surrounding concrete.
With the right tools and materials, you can fix these small surface cracks yourself. Start by gathering what you will need: a pressure washer or brush, concrete patching compound, and a caulk gun.
First, clean the area thoroughly. Remove any loose debris, dirt, or old concrete from the crack. Using a pressure washer makes this job much easier, but a wire brush works too. Just make sure the crack is completely clean and dry before moving forward.
Your main repair material will be a flexible concrete caulk or concrete patch designed for narrow cracks. Pick one that matches your existing concrete color for the best results. You’ll also need safety glasses and a putty knife to ensure a smooth application.
Keep in mind that proper preparation is key to ensuring your repair lasts. If you spot lots of hairline cracks, consider consulting a professional to check for underlying issues.
Fixing those moderate cracks in your concrete sidewalk requires a bit more effort than hairline repairs. For cracks wider than 1/8 inch, you’ll want to use a combination of backer rod and self-leveling sealant for the best results.
Start by cleaning the crack thoroughly with a pressure washer. Once the area is clean and dry, insert the backer rod into deep cracks. This rod helps support the repair material and prevents it from sinking too deep into the crack.
Next, load your caulk gun with a self-leveling concrete repair compound. Apply it carefully over the backer rod, making sure to fill the crack completely. Use a concrete finishing brush or trowel to smooth the surface and match the surrounding concrete texture.
Let the repair cure as directed on the label. This step is critical for ensuring your concrete repair holds up over time. While the concrete is drying, protect it from foot traffic and weather elements.
When you notice deep cracks or cracks wider than 1/4 inch in your concrete walkway, it’s time to think twice about DIY repair. These larger cracks often signal serious issues beneath your concrete slab that need expert attention, especially if you spot signs of heave or uneven surfaces.
Your concrete walkway might need professional help if concrete slabs are not level or have shifted from their original position. Major settlement problems typically show up as uneven surfaces where parts of your concrete driveway or walkway sit lower than others, often due to soil issues or problems with the initial concrete installation process.
Professional concrete repair specialists bring specialized equipment and expertise beyond basic home improvement tools. They use industrial-grade pressure washers, concrete finishing brushes, and advanced repair techniques like slab jacking – a process that pumps material under your concrete to lift and level it. These specialists can properly assess if your concrete is sound enough for repair or needs complete replacement.
Tree roots, severe heave, or extensive damage might require removing and replacing sections of your existing concrete. Professionals use specialized concrete mix formulas and proper forming techniques with two pieces of wood to ensure lasting results. During installation, they will use concrete insulating blankets to ensure proper curing of the new concrete.
Remember, attempting to fix major concrete problems yourself might lead to costly repairs later. When in doubt, consult a professional who can provide a free onsite cost estimate. Their expertise helps determine whether repair or replacement will provide the most cost-effective, long-lasting solution for your damaged concrete walkway.
Don’t wait if you spot these warning signs – reach out to professionals who have worked with damaged concrete locally. They can evaluate your situation and recommend the best solution for your cracked walkway.

Technically its possible to pour new concrete over old, this approach often leads to disappointing results. The existing cracks typically reflect through the new layer, and underlying problems remain unaddressed. Instead, focus on proper repair or replacement of severely damaged sections for a lasting solution.
Your choice of filling material depends entirely on crack characteristics. Hairline cracks respond well to specialized concrete crack fillers, while larger cracks require concrete patching compound combined with backer rods. Match your repair material to the specific situation for optimal results.
The decision between patching and full repair depends on several factors. Small, isolated cracks often respond well to patching, proving both cost-effective and practical. However, extensive cracking, heaving, or settling usually signals deeper problems requiring comprehensive repair or replacement. Consider the crack’s cause, size, and location when making your decision. Sometimes, investing in full repair now prevents costly replacements later.
