The average cost to replace a garage floor is $4,300, but the size of the garage and type of floor can lead to a variation in price. Most people pay between $2,400 and $11,200, but you can call a garage floor pro for a more accurate estimate based on your garage’s specifications.
Garage floor replacement costs $4,300 on average, but you could pay as little as $480 or as much as $18,100. It’s safe to say that the garage gets pretty heavy traffic—both foot traffic and literal traffic from your car. This can quickly lead to a cracked surface, which could be detrimental to the total foundation of your home. The cost to redo a garage floor encompasses a lot of different factors, and we’ve got them all lined up for you so that you can start budgeting.
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.
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.
| Garage Size | Square Feet | Average Cost |
|---|---|---|
| One-car garage | 240 | $480–$3,700 |
| Two-car garage | 400 to 484 | $800–$6,800 |
| Three-car garage | 864 to 1,296 | $1,700–$18,100 |
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.
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:
| Flooring Material | Average Cost Per Square Foot |
|---|---|
| Concrete with epoxy | $2–$12 |
| Vinyl flooring | $2–$7 |
| Carpet | $3–$5 |
| Rubber | $1–$2 |
| Ceramic tile | $4–$8 |
| Porcelain tile | $2–$15 |
| Porcelain wood tile | $3–$12 |
| Rectified tile | $6–$8 |
| Slate | $4–$10 |
| Glass | $10–$180 |
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
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.
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
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.
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.

If you're only working with a gravel pad, and there is no concrete foundation, you might be able to upgrade to a concrete slab, but you’d have to speak with a professional concrete expert to confirm and get pricing. If you have a concrete foundation or cement block walls around the area where you want to build flooring, you might be able to pour a new concrete floor over the existing one to forgo repairs. Again, speak with a concrete expert or foundation company to see if this is an option.
Resurfacing a garage floor takes about eight hours on average, with another couple hours over three days to do the epoxy. Epoxy goes on in three coats, with each coat taking 24 hours to dry and cure. You’ll need to keep foot and vehicle traffic off of your garage floor for around 4 days in total when replacing your garage floor, so be sure to plan ahead before you start. This is a great time to organize your garage since you’ll need to move everything out to apply the epoxy.
Epoxy helps protect your garage floor from moisture, staining, and cracks over time. Concrete itself is typically porous, and epoxy fills those tiny holes and creates a smooth finish. Installing garage floor epoxy may also extend the life span of your garage to upwards of 20 years, as it strengthens the concrete and helps prevent water from seeping through it.
If your cement garage floor is sinking and cracking, your first step should be to call a local structural engineer to assess the problem. They can determine if it’s a minor amount of sinking related to normal settlement or if the issue is structural in nature. If you do have structural damage, the engineer or a foundation repair company that you hire will come up with a plan to fix the issue, which often consists of mudjacking for less severe issues or underpinning for more extensive problems.
Generally speaking, epoxy is the best garage floor coating. There are two main types of garage floor coating you can consider: epoxy and polyaspartic. Epoxy coating comes at a more affordable price but loses when it comes to durability and long-term use. Polyaspartic coatings cost more and don’t offer as much traction, but they withstand accidents better and don’t tend to fade. Most homeowners choose an epoxy coating.
The concrete that likely already makes up your garage floor is the longest-lasting garage floor material, although you can treat it with a variety of coverings to improve its durability. Epoxy is one of the most popular options, as it’s relatively affordable, adds strength to the floor, helps prevent staining and physical damage, and even improves the resistance to water intrusion. Other popular options for durable floor coverings include rubber, an aspartic coating, and vinyl.
