How Much Does Garage Floor Replacement Cost? [2025 Data]

Garage Floor Replacement Cost Breakdown

The local cost of living will determine what you pay for labor, but there are a few other items that affect the final price of a garage floor replacement, including structural testing and repairs. Then you can get to the more fun decisions, like deciding if you want to stain or stamp your concrete. 

Whatever your plans are, it’s essential to know the price tag of your project. Here’s a breakdown of garage floor replacement costs.

Size of Garage Floor

On average, the cost to replace a garage floor is $7 per square foot, but prices range from $2 to $14 per square foot. Flooring for one-car garages (roughly 240 square feet) costs $1,680, and flooring for two-car garages (roughly 440 square feet) costs $3,080.

The cost to replace a garage floor will depend on what parts of the job you tackle yourself. Doing minor repairs and recoating can save you $3 to $4 per square foot if you’re confident in your DIY abilities. However, if you make a mistake DIYing it, you’ll pay double the price, plus a couple of wasted afternoons. 

Keep in mind that installing a new floor in your garage can also mean that you’ll need a garage door replacement if the new floor is too high. If your garage door won’t close after replacing the floor, you’ll need to start budgeting for a replacement.

Type of Flooring

Don’t feel like you’re stuck with the same concrete flooring that’s been there since you bought the home. While concrete flooring is the standard, you can always put different flooring over it if you want to change the purpose of the garage.

The price depends on the type of flooring material and size. For example, glass tile costs much more than carpet or vinyl. Here’s the average cost of garage floor replacement per square foot for each type of material:

Structural Testing

Since the garage floor is often a part of the concrete foundation of the home, you’re likely going to need to call out a structural engineer to verify that there are no structural issues. You might also be required to have a geotechnical engineer come out to test the soil to make sure the land is still suitable to build on.

Common prices for evaluations include:

• The cost to hire a structural engineer: $550 for a single report

• The cost to hire a geotechnical engineer: $1,500 for a single report

Repair

In the event that either of these reports brings about needs for repairs, then they are considered a priority, and you’ll need to tackle these issues first. These can be small repairs that only cost you around $10 to tackle yourself. 

Or it could be something major such as foundation repair, which could cost upwards of $5,000. Below are some common garage floor repairs and associated costs you might run into:

• Sealing hairline cracks: $10 to $250

• Sealing leaking cracks: $150 to $500

• Concrete leveling: $220 to $1,000

• Mudjacking: $300 to $3,300

• Underpinning: $3,000 to $10,000+

Garage floor repairs will tend to be more expensive in attached garages because the foundation issues are usually more severe. Repairs in detached garages cost less in most cases because issues are often not as severe and because the slab tends to be easier to access from all sides.

Staining or Stamping

The garage doesn’t need to be a dull and boring place where you just park your car. You can spruce it up by adding in different colors or textures, though doing so will raise the overall price.

The cost to stain a concrete floor can vary by type of concrete:

• Single stain: $4 per square foot

• Multi-stain: $10 per square foot

• Stamped concrete: $14 per square foot

Comparing Garage Floor Replacement vs. Repair

You don’t always have to jump straight to garage floor replacement when issues arise; in many cases, you may simply need to make some basic epoxy repairs. Repairing garage floor damage is an attainable DIY task if you have a free afternoon and some tools at your disposal; here’s how to repair a concrete garage floor in six easy steps.

So how can you tell if your garage floor can simply be repaired or if it’s time for a total replacement? Here are a few things to consider:

• How old is the concrete floor? Concrete doesn’t last forever. If it’s more than 20 years old, it’s probably smarter to replace the entire floor rather than attempt to fix individual cracks. But if the concrete is only a few years old, it may be worth it to try to repair individual cracks rather than replace the entire floor.

• How extensive are the cracks? Repairing garage floors by filling in cracks with epoxy filler is a simple DIY project, but if the floor is suffering from more than basic surface cracks, you may need to consider a replacement. Long, deep, and wide cracks can let water in; as it freezes and thaws, it will lead to further deterioration of your garage floor.

• What’s the issue? Concrete crack repair is a great alternative to full garage floor replacement, but if there are other issues with the floor or foundation, such as a sinking concrete slab or ineffective water drainage, it may be best to install an entirely new garage floor.

DIY Garage Floor Replacement vs. Hiring a Pro

Just resurfacing a garage floor yourself costs around $2 to $5 per square foot on average. You can tackle this project as a DIY only if you’ve worked with concrete in the past. However, garage floor work is labor-intensive, and even small mistakes can be costly. 

Unless you have an advanced understanding of flooring—whether you’re pouring concrete or installing tiles—we recommend working with a garage floor contractor near you to get the job done right.
