Assessing the Type and Severity of the Crack

Before you begin the repair process, it is important to assess the type and severity of the crack in your concrete. Hairline cracks are typically less than 1/4 inch wide and can be easily repaired with a simple DIY method. However, larger cracks may require professional help to ensure they are properly fixed.

Materials and Tools Needed for the Repair

To repair small cracks in concrete, you will need the following materials and tools:

  • Concrete crack filler
  • Putty knife or trowel
  • Wire brush
  • Safety goggles and gloves
  • Clean water

Step-by-Step Guide to Repairing Small Cracks

  1. Start by cleaning the crack with a wire brush to remove any debris or loose concrete.
  2. Fill the crack with concrete crack filler, making sure to smooth it out with a putty knife or trowel.
  3. Allow the filler to dry according to the manufacturer’s instructions.
  4. Once the filler is dry, use a wire brush to blend the repaired area with the surrounding concrete.
  5. For a professional finish, you can also apply a concrete sealer over the repaired area to protect it from future damage.

By following these simple steps and using the right materials and tools, you can successfully repair small cracks in concrete without having to hire a contractor. Remember to always wear safety goggles and gloves when working with concrete and follow all manufacturer instructions for the best results.

When to Seek Professional Help

If you are dealing with complex cracks in your concrete that are beyond the scope of DIY repairs, it may be time to seek professional help. While minor cracks can often be repaired by homeowners, there are certain situations where the expertise of a contractor is necessary.

Identifying Complex Cracks Requiring Expert Attention

Complex cracks in concrete may include structural damage, extensive cracking throughout the surface, or cracks that are reoccurring despite multiple repair attempts. If you notice any of these signs, it is best to consult with a professional contractor who can assess the extent of the damage and recommend the appropriate course of action.

Knowing When DIY Repairs are Not Sufficient

While DIY repairs can be effective for minor cracks, there are instances where they may not be sufficient. If you have attempted to repair the cracks yourself and they continue to worsen or reappear, it is a sign that the damage is more severe than initially thought. In these cases, it is important to seek the expertise of a contractor who can provide a long-lasting solution to the issue.


In conclusion, repairing cracks in concrete without a contractor is definitely possible with the right tools, materials, and knowledge. By following the steps outlined in this article, homeowners can save money and take on this DIY project themselves. However, it is important to assess the severity of the crack and determine if professional help is needed for more serious issues. With proper maintenance and timely repairs, homeowners can prolong the lifespan of their concrete surfaces and keep them looking great for years to come.
