Are Cracks in the Garage Floor Normal?

While a few cracks in your garage floor are probably nothing to worry about, large or numerous cracks could be indicative of a more serious problem.

Foundation issues are one of the most common causes of cracked concrete floors, so if you notice any cracks in your garage floor, it’s important to have them inspected by a professional as soon as possible. In some cases, cracked concrete floors can be repaired. However, in other cases, the entire floor may need to be replaced. 

Whether or not repairs are possible will depend on the extent of the damage and the underlying cause of the cracks. If you’re not sure whether or not your garage floor needs to be repaired, it’s always best to err on the side of caution and consult with a professional.

What else causes garage floor cracks? Some of the most common culprits are:


Garage floors are subject to a lot of wear and tear. Over time, they can develop cracks, chips, and other damage. While many people assume that this damage is caused by poor quality materials or poor construction, the truth is that it is often the result of settling. When a house is first built, the foundation is not yet set. 

The weight of the house causes it to settle into the ground, and this process can cause cracks in the garage floor. In addition, as the house settles, the soil around the foundation may shift, resulting in additional pressure on the garage floor. 

As a result, it is important to have your garage floor inspected regularly for signs of settling so that you can take steps to prevent or repair the damage before it becomes too severe.


Cracks in your garage floor can be more than just an eyesore–they can be indicative of a serious problem. One common cause of cracks is shrinkage. As concrete dries, it naturally shrinks. This process is usually gradual and happens over the course of several years. 

However, if the concrete dries too quickly or unevenly, it can cause the material to crack. Shrinkage is often exacerbated by temperature changes and moisture levels, both of which are common in garages.

Poor Installation 

While these cracks can be caused by a variety of factors, such as weather changes or poor drainage, they are often the result of poor installation.

If the concrete is not properly prepared before the flooring is installed, it can lead to a weak bond between the concrete and the flooring material. This can cause the flooring to shift and crack over time.

In addition, if the flooring is not installed level, it can also lead to cracking.

Poor Drainage

One of the most common causes of cracking is poor drainage. If water isn’t able to drain away from your garage floor, it can seep into the concrete and cause the ground to shift. This can eventually lead to cracks forming in the floor.

In addition, standing water on your garage floor can also cause problems with mold and mildew. As a result, it’s important to make sure that your garage has good drainage in order to avoid these issues.

Accidental Injury

Cracks can occur for a variety of reasons, but one of the most common is accidental injury. A dropped tool or piece of equipment can easily create a crack, as can a heavy object that is dropped onto the floor. In addition, parking a vehicle on an uneven surface can also cause cracking.

Garage floors take a beating from cars, tools and weather. Over time, the concrete can begin to crack and crumble. 

While some people may think that these cracks are purely cosmetic, they can actually lead to a variety of problems. For example, cracks can provide a place for water to seep in, which can lead to freeze-thaw damage or even mold growth.

In addition, cracks can destabilize the entire floor, leading to chips and flakes. Not only is this unsightly, but it can also create a trip hazard.

As a result, it is important to repair garage floor cracks as soon as they appear. 

How Do You Treat Cracks in a Garage Floor?

There are several ways to repair cracks in a garage floor, depending on their size and severity. For small hairline cracks, mix a batch of epoxy resin and use a putty knife to fill the crack. 

Larger cracks may require the use of a concrete saw to create a clean, straight edge before filling. For very large or deep cracks, it is best to consult with a professional contractor who can evaluate the damage and suggest the best course of action. 

For a DIY fix, we’ll walk you through the simple steps below, but here’s a helpful video to walk you through the process:

If you have cracks in your garage floor, you may be wondering how to fix them. 

  1. First, it’s important to evaluate the crack to determine how severe it is. If the crack is only a few millimeters wide and doesn’t go all the way through the floor, it can likely be repaired. 
  2. However, if the crack is more than a few millimeters wide or goes all the way through the floor, it will need to be replaced. To repair a small crack, start by using a chisel to cut along both sides of the crack. 
  3. Then, use a hammer to chip out the cracked area of concrete. Once the area is cleared, fill it in with concrete filler and Smooth it over with a putty knife. 
  4. Finally, add resurfacer to the crack to help blend it in with the rest of the floor. 

By following these steps, you can easily repair small cracks in your garage floor.

How Much Does it Cost to Fix Cracks in Garage Floor?

Depending on the size and severity of the cracks, the cost to fix cracks in the garage floor can vary. 

For small cracks, a simple repair kit with epoxy glue can be sufficient. These kits typically cost between $10 and $20. For more significant cracks, however, you may need to replace the entire section of concrete. 

The average cost to replace a section of concrete is around $300. If the cracks are due to a structural problem, such as settling foundation, the repair costs can be much higher. In these cases, it is best to consult with a professional to assess the damage and determine the best course of action. 

Ultimately, the cost to fix cracks in the garage floor will depend on the cause and severity of the damage.
