Installing Hardwood Floors Over Concrete Floor


Can Hardwood Floors Be Installed Over Concrete? The simple answer to this question is yes, hardwood floors can be installed on an already present concrete floor. But there are some things that you should keep in mind before installing a hardwood floor over a concrete floor. The first thing that you should keep in mind that your concrete floor should not contain any moisture or dampness. You cannot install a hardwood floor of any type over a concrete floor that has a higher level of moisture in it. This is because the moisture in the concrete floor would destroy the wooden floor. The article below is a complete guide for installing a hardwood floor over a concrete flooring surface. Let’s start with the advantages of installing a hardwood floor over a concrete floor.

Advantages of Hardwood Flooring Over Concrete

Here are some of the advantages of a hardwood floor over a concrete floor.

  • Protection: When you install a hardwood floor over the surface of a concrete floor, the concrete floor provides hardwood floor protection. It protects the structure of the hardwood floor by providing a hard base. So, when pressure is applied over the surface of the hardwood floor, the concrete floor provides support and helps avoid bending or dents in the hardwood floor. Not only this, but it also protects the hardwood floor from other damages including protection from dampness and moisture as well.

    This damage protection of hardwood floors increases the age of the hardwood floors. Making the hardwood floors more durable and long-lasting. This protection also helps avoid the costs for repairs, as it protects against damages. This means the floor is less likely to get damaged and less likely to require repairs, hence saving a lot of time and money that otherwise would have been spent on the repairs.
  • Aesthetics: Concrete floors do not look good on their own as they have a rough, rigid, and colder surface. But installing a hardwood floor over the surface of a concrete floor can increase the beauty of your place and make it look more aesthetic. There are a lot of colors, shapes, sizes, grain structures, and other options in wooden floors that concrete floors do not provide. That is why installing a hardwood floor over the surface of the concrete floor would make it look more beautiful. So, if you are looking forward to upgrading your concrete floor, it is a good idea to install a hardwood floor over its surface. 
  • Warm and Soft under the feet: Concrete floors are extremely cold, hard, and have rough surfaces. All this can be felt when you are walking over the surface of such a floor. To get rid of this hard and unpleasant feel when walking, you should install a hardwood floor. The hardwood floors, unlike the concrete floors, absorb light and hence they remain warm. Also, the surface of these floors is far softer than the concrete and this can also be felt when you are walking over the surface of a hardwood floor. Apart from these, hardwood floors also have a smoother surface in comparison to the concrete floor. So, if you want to transform your inner concrete floor into a much more pleasant, warm, and softer floor with a smooth surface, you should install a hardwood floor over it.
  • Increased Value: Homes with concrete floors do not have any value in terms of flooring. That is why it becomes difficult for the homeowners to sell such a property. Whenever buyers visit your property, they first take a look at the floor and its condition. So, if you have a concrete floor, most of the buyers would not return.

    This is because buyers prefer a home with a decent type of floor. You can attract more buyers if you have installed a hardwood floor, not only this but buyers will show more interest in your property if you have a hardwood floor. This can help you increase the value of your property and make some profit.

You have learned about the benefits of having a hardwood floor over a concrete floor, now it is time to know what factors impact the installation of a hardwood floor over a concrete floor.

Factors to Consider for Hardwood Floor Over Concrete

Here are some of the important factors that impact the hardwood floor installation and maintenance of the hardwood floors over a concrete floor.

  • Understanding the Grade Level: Before installing a hardwood floor over the surface of a concrete floor, you must understand the grade level system. There are three types of floors based on this grade level system. One is known as above-grade floors.

    These are the floors that are above the ground or not attached to the ground directly. Consider the ceiling of your home or the floor of your upper story. The second type of floor is on-grade flooring. This is the floor that is aligned with the ground. Consider it a ground-level floor. The third type of floor that you have is known as a subfloor. It is a floor that is below the ground. It is also known as the below-grade floor.
  • New and Old Concrete Floor Difference: It is also important that you should know if your concrete floor is new or old. There is a chance that older floors have more damage on their surface and that is why they require extra work on the repair before installation of the hardwood floor. But the new floors also have a problem with moisture. The new floors have more moisture in them as they need to completely dry first and then you can install a hardwood floor over the concrete floor.
  • Moisture level in the Concrete Floor: Checking the moisture in your concrete flooring is important. If the moisture level in your concrete floor is higher, it would immediately destroy your hardwood floor. To avoid this kind of destruction of the hardwood floor, you should first check the floor for moisture, if it is high, use different techniques that are required to make the concrete floor completely dry and moisture-free.

Another important thing, if your concrete floor has some level of moisture that is not going away, try to use concrete floor sealers to make sure that moisture does not seep into the hardwood floor and causes any damage. So, before installing hardwood floors over the concrete floor, you should check the level of moisture in the concrete floor.

  • Flatness – Level of the Concrete Floor: It is also important that you should check the flatness of the surface of your concrete floor before installing any hardwood floor over it. This is important because if your concrete floor does not have a flat or level surface, there is a chance that the hardwood floor would get dents over its surface. To make sure that your hardwood floor remains flat and, on the level, you should check the flatness.

    If you find any spot in your concrete floor that is not on the level or is damaged, try to make it as flat as possible. You can also repair the cracks, and damaged parts of the concrete floor to make sure it stays flat completely under the hardwood floor and provides equal support for the entire planks of the hardwood floor. This would protect the hardwood floor planks from denting, or rupturing.

You have learned about the things that you should consider before installing a hardwood floor over the surface of a concrete floor. It is time to know about installing a hardwood floor over a concrete floor.

If you do not remove the old floor completely, the surface of the concrete floor would not be flat, this could cause dents and the unlevel surface of the floor. After removing the old floor from the surface of the concrete floor, it is time to remove any paint or sealer from its surface as well.
  1. Check Concrete Floor for Moisture: After completely removing the old floor from the concrete flooring, it is time to check the concrete floor for moisture. There are a lot of devices that you can use, but if you do not have any devices, you can also talk about the moisture in the concrete floor by taking a close look at the floor surface. If the floor has signs of wetness, or white powder is spread over its surface, it is impacted by the moisture.

    But to be completely sure about this situation, it is suggested that you use a device that can tell you about the moisture level in the concrete floor. Make sure that your concrete floor has the lowest amount of moisture in it. If the level of moisture is higher, try using heaters, to heat the floor. The heat from the heaters will absorb all the moisture and dampness from the concrete floor.
