Garage floors deal with heavy pressure. Cars and other vehicles can be driven over them, boxes of items can be stacked on top, and they usually do not get the same care and maintenance as other floors. It is natural for the garage floor to wear, leading to cracks, holes, stains, and sagging sections. Call a garage floor repair company or contractor to fix the damage when issues like this arise.
The national average cost for garage floor repairs is between $500 and $1,750, with most homeowners paying around $1,000 to resurface and patch a 240 sq.ft. pitted garage floor. However, prices may be significantly higher or lower, depending on the issue and repair type. This project’s low cost is $100 to pressure wash a 240 sq.ft. concrete garage floor. The high cost is $4,000 for major mold remediation in a 240 sq.ft. garage.
|Average Cost to Repair a Garage Floor|
|National average cost||$1,000|
The average cost of garage floor repairs is between $2 and $7 per sq.ft. Some contractors and repair companies use square footage to calculate their costs. This is especially relevant with big jobs like large-scale resurfacing or garage floor cleaning and sealing. However, contractors may charge based on the amount of effort or hours they spend repairing rather than the size of the issue for smaller jobs like patching holes and cracks. Speak with your licensed contractor before work begins to understand the costs.
Most garage floors are concrete. This material is chosen due to its strength and resistance because it can cope with heavy loads and high pressures better than other materials. Epoxy is another relatively common garage floor material. There are others, such as rubber and stone, but these are rarely used. We focus on concrete and epoxy in this guide because they are the most common choices for garage floors. The table below shows average repair costs for each, based on a standard 240 sq.ft. single-car garage.
|Concrete||$400 - $1,500|
|Epoxy||$500 - $1,600|
The average cost to repair concrete garage floors is between $400 and $1,500. Concrete is a very common and popular choice for garage floors because it is strong. It can withstand the weight of a vehicle without buckling under the pressure. Concrete is also relatively low-maintenance, requiring little cleaning and fewer superficial repairs than other flooring materials like vinyl 1. However, it can still suffer from stains, cracks, holes, and crumbling, so it may require patching, resurfacing, and cleaning.
Homeowners pay between $500 and $1,600 for epoxy garage floor repairs. Epoxy is applied to concrete floors to make them stronger and more durable, so when we talk about epoxy floors, we refer to epoxy and concrete together. These floors can be more expensive to repair because of the price of epoxy, but they may last longer than regular concrete. Common issues include cracks, sinking sections, holes, and oil stains. Repair methods for these problems include patching and resurfacing.
Many problems can occur with your garage floor. These include relatively minor issues like small cracks and holes that need to be filled and patched to bigger problems like uneven or sinking sections. Certain problems are much quicker and cheaper to fix than others. The table below shows average costs for common garage floor issues, based on a single-car 240 sq.ft. garage.
|Oil Stains||$100 - $250|
|Crack||$150 - $1,000|
|Holes||$150 - $1,000|
|Salt Damage||$200 - $750|
|Spalling||$500 - $2,000|
|Pitted||$500 - $2,000|
|Sinking||$500 - $2,500|
|Uneven||$500 - $2,500|
|Leaking||$750 - $3,000|
|Crumbling||$750 - $3,000|
|Mold||$1,500 - $4,000|
It costs between $100 and $250 to remove oil stains on your garage floor. Oil stains commonly appear on garage floors when vehicles are stored inside the garage. These stains do not necessarily cause damage, but they can be unsightly and ruin the aesthetic. A professional contractor can use WD-40, grease cleaner, concrete cleaner, and tools to wash the stains and leave your floor looking clean and new.
The average cost to repair a cracked garage floor is between $150 and $1,000. The total cost depends on the crack size and depth. Cracks appear naturally on garage floors over time or may appear suddenly due to an impact or accident. The crack must be filled and patched to prevent further damage. Cracks that are not fixed quickly may grow larger, deeper, and more problematic, so act fast.
Homeowners usually spend between $150 and $1,000 on repairs for holes in a garage floor. The total cost depends on the size and depth of the holes. Filling one small hole is much quicker and cheaper than filling multiple large ones. Holes may appear due to wear and water damage. They must be filled and patched to avoid further damage.
The average cost to repair a salt-damaged garage floor ranges from $200 to $750. Salt damage is common in cold and snowy areas because salt from the roads can be brought into the garage and left on the floor. This leads to ugly white stains and other issues like spalling and pitting. It may need to be cleaned, patched, and lightly resurfaced.
Homeowners spend between $500 and $2,000 to repair spalling damages to your garage floor. Spalling is the technical term for freeze-thaw water damages. This is when small amounts of water freeze and thaw in tiny holes or cracks, making those holes and cracks bigger over time and wearing at the top layer of concrete. This can expose the weaker aggregate underneath. Resurfacing may be needed to fix spalling damages.
Homeowners pay between $500 and $2,000 on repairs for pitting in concrete garage floors. Pitting is when little holes appear on the surface and go deep down, allowing water to seep in and do damage. This may be caused by improper installation, salt damage, and exposure to certain chemicals and fluids. The area usually must be cleaned and patched with epoxy, resin, or cement to fix pitting.
If your garage floor is sinking in certain areas, expect to spend between $500 and $2,500 to fix it. Leveling 2 must be used to fill the sinking sections or lift them up. Filling the sunken areas can be cheaper but may not be possible, and slabjacking may be required, which can be more expensive. Call a contractor to look at the issue and decide the best action.
The average cost to fix uneven areas of a garage floor ranges from $500 to $2,500. The total cost depends on how much of the floor is uneven and which leveling method is chosen to fix it. Filling the uneven areas can be an efficient and affordable method, but slabjacking might also be required to push the foundations from below, raising costs.
If your garage is leaking at the floor level, expect to spend between $750 and $3,000 on repairs. Various possibilities cause a leaking garage, including cracks in the floor, pitting, and other damages. The floor may need some patching or resurfacing, and it may have to be sealed to prevent leaks.
If your garage floor is crumbling in certain areas, prices average $750 to $3,000 for repairs. Crumbling can be a serious problem on concrete floors because the crumbled areas are weaker and less stable, and the damage can quickly spread. The crumbling parts are usually removed, and new concrete can be poured in to fix this issue. A sealant may also be used to protect the area against further damage.
If you have mold on your garage floor, expect to spend between $1,500 and $4,000 on professional mold remediation services. Mold is common in garages because they are less insulated than other parts of the home, so water can seep in easily. It may grow in corners and dark spaces around the garage and on items stored inside it. Some of the most common types include black, green, and white mold.
A range of repair methods or solutions can fix common garage floor problems. For example, filling and patching are commonly used for holes and cracks, while pressure washing removes marks and stains. The table below shows a range of garage floor solutions and the average costs for each, based on an average single-car 240 sq.ft. garage.
|Power Washing||$100 - $250|
|Filler||$150 - $750|
|Patch||$150 - $1,000|
|Level||$500 - $2,500|
|Resurface||$960 - $2,400|
The average cost to power wash a garage floor is between $100 and $250. This solution is mainly used for aesthetic reasons and to clear spots, stains, and marks. It can be useful for reviving an old and tired-looking floor and may help remove lingering mold or mildew after a mold treatment.
Homeowners spend between $150 and $750 on filling garage floors. This solution is most commonly used when dealing with holes and cracks. The holes or cracks are filled with a special filling material like epoxy or resin. In some cases, a sealant may be applied at an additional cost to prevent further damages.
Patching a garage floor averages $150 to $1,000. Patching is a common repair method for when the floor suffers from wear, cracks, pitting, and spalling. Special concrete floor patches can cover these damaged sections, filling in holes or weak areas and strengthening the floor.
Garage floor leveling costs average $500 to $2,500. This solution is used on uneven sections of the garage floor. There are two forms of leveling: applying compound and slabjacking. Applying compound involves using a special self-leveling concrete filler material on low areas of the floor. This is best used for small and uneven areas. Slabjacking is a more intensive leveling method that involves pumping 3 material under the floor to lift it. This is best used on larger sagging and sinking sections.
The average cost to repair and resurface a garage floor ranges from $960 to $2,400. Resurfacing is used to revitalize and strengthen old garage floors that may have various stains, superficial damages, and problems like spalling. This process involves cleaning the floor, filling deep holes and cracks, and applying new concrete resurfacing materials over the top to make the floor look new.
Contractors and garage floor specialists charge between $50 and $100 per hour. Prices may be higher or lower, depending on the amount of competition in the area. Some charge by the hour, while others have set fees and flat rates for different garage repairs.
Those in remote areas may also have to pay extra to cover the workers’ travel costs. You may also need to pay an additional $50 to $100 per job if you need urgent same-day garage floor repairs. For example, if you have a crumbling section of floor in the garage that makes it impossible to use safely, you might want the repairs done as quickly as possible.
Many contractors charge by the hour for their services, and fixing garage floors can take a couple of hours to a full day or several days. Contractors may offer discounts on very large jobs or have set fees for specific repairs like filling a hole or patching a crack.
Keeping your floor well-maintained is one of the best ways to reduce the risk of garage floor problems and reduce the amount you spend on garage floor repairs. Homeowners can do several items to look after their garage floors, and one of the first things is to treat your garage floor with respect and care.
Homeowners tend to worry less about garage floors than other floors. You might walk on your garage floor in dirty boots or throw things into the garage without much care, for example. However, you can extend the floor’s lifespan by treating it more carefully.
Another good tip is to keep your garage floor clean. You can use a broom to sweep surface dirt that accumulates. This can be done weekly, and you can do a deeper sweep and clean every few months. Look for stains or rust marks during a deep clean and scrub them away with hot soapy water or white vinegar solution.
Watching your garage floor and looking for warning signs like surface cracks, holes, spalling, or mold is also useful. If you spot something, take action and deal with it as soon as possible.
It can be really important to apply a coating or sealant to your garage floor. Sealants and coatings protect the floor’s lower layers against moisture damage, oil, grease, and other materials like road salt and de-icing fluids. Coatings should be reapplied every 2 to 5 years.
If your garage floor is heavily damaged or old and worn, you may want to consider replacing it rather than repairing it. However, before you decide, think about two factors: cost and age. Replacing a standard 240 sq.ft. garage costs $1,680 to $4,800, which works out to around $7 to $20 per sq.ft. This covers demolishing the old floor and pouring new concrete. This is significantly higher than the average repair cost, ranging from $500 to $1,750.
So, if the estimated price of your garage door repairs is similar to this, or you have to spend money on recurring floor problems, it may be best to fit a new floor. Age is another factor. Garage floors last 15 to 25 years with regular care and maintenance, but they are more likely to develop issues and need repairs as they get older. An old floor could cause you trouble, so getting a new one might save money long-term.
It is also worth noting that you do not necessarily need to demolish your old floor to install a new one. It may be possible to pour new concrete over the top. The cost to pour concrete over a garage floor is usually significantly cheaper than demolishing and removing the old one, so this may be something to ask your contractor. The table below shows how the average repair and replacement costs for garage floors compare to one another, based on a 240 sq.ft. garage.
|Repair||$500 - $1,750|
|Replace||$1,680 - $4,800|
Homeowners spend between $500 and $1,200 to paint a standard single-car 240 sq.ft. garage floor. Painting your garage floor is a good way to improve its look, make the space more attractive, and provide a barrier of protection against dirt, debris, oil spillages, and other messes. You can choose from various paints and save some money by painting the floor yourself. Epoxy paint is the best variety on garage floors.
Adding rubber tiles 4 to your garage floor costs $240 to $720 for a 240 sq.ft. space, or between $1 and $3 per sq.ft. Rubber floor tiles are not suitable for spaces where you plan to park your car. However, rubber flooring can be a cheap and reliable option if you use your garage for other purposes like a home gym, chill-out area, man cave, or guest room. It is anti-slip, easy to install, and provides extra warmth and insulation underfoot to enjoy while walking around, so it can be useful for enhancing your floor’s usage and comfort after repairs.
If you need to seal your concrete garage floor, expect to pay between $2,400 and $3,600 for a full 240 sq.ft. floor. The price depends on which sealant you want to use. Some sealant materials are stronger, more resistant, and more expensive. Sealing is a great method to protect your garage floor against water damages and oil and gasoline spills.
It depends on the type of damage. Repair methods may include patching, filling, resurfacing, and leveling for holes, cracks, and uneven sections.
Different methods may be used for varying problems. For example, an uneven floor might need slabjacking, while a floor with spalling or pitting might need to be resurfaced.
The best repair method for spalling is usually to resurface the floor. This involves applying new concrete and special resurfacing materials to reinforce the damaged areas.
Yes, but the cracks must be filled or patched. A layer of epoxy can be applied once this is done.
Yes, it is normal for most garage floors to develop cracks. However, you should not leave the cracks because they can get deeper and wider. Fill or patch them to prevent further damage.
A concrete floor might crack for various reasons. It could be due to too much pressure, temperature changes, shrinkage and expansion, or settlement as the soil under your home moves.
