Are Squeaky Floors A Structural Problem?

Squeaky Floor

No matter where you lived, you probably immediately interacted with a squeaky floor that makes the freaking voice every time. It could be more irritating and terrible at midnight when you go to the kitchen to drink water and hit a squeaky floor. Unfortunately, this squeakiness will go wild over time.

If you want to get rid of these annoying voices, you have to instantly maintain or treat your floor. It doesn’t mean that you have to hire a professional every time for this issue. You can also deal with it yourself after reading this post.

There are several reasons behind the squeaky floors, including the poor installation and low quality of wood. So, you cannot choose a treatment for the surface without knowing the leading cause.

If you also think that the noisy floor occurs because of a structural problem, we will help to clear this concept with more details and facts. Let’s start focusing on each cause behind the noisy floor to find out the right solution.

Reasons Behind Squeaky Floor:

If you want to eliminate the irritating noises out of your wood floor, you have to focus on the main reason behind this issue. A squeaky floor is not always because of poor installation. That’s why stop blaming the contractors and consider the correct facts to get the right solution. There would be many reasons behind an inappropriate and noisy floor. Let’s discuss a few of them.

Changes In Humidity Level:

Undoubtedly, most people don’t consider this fact. But changes in the humidity levels surely disturb the structural pattern of the wood floor. So, the seasonal expansion because of humidity might be the main reason for the squeakiness of flooring.

We all know that wood expands because of moisture and the absorption of water from the air. On the other hand, you may suffer from the wood contraction issue in the winter season. The contraction creates gaps between the floorboards. The cracks and gaps create noise out of the floor when you step on it.

The best thing is that you don’t need to worry about the seasonal contraction because it will go when the spring or summer arrives.

Issues In the Floor’s Layers:

If your floor is facing the squeakiness issue, it might be because of inappropriate floor layers. Basically, the wood floor is based on the upper layer, joists and lower layers. The main reason for considering the joists in the wood floor structure is to increase the integrity. Contractors install the joists using nails. If you hear some freaking noise out of your floor, it may be because of losing joist nails.


You have to tighten the nails for complex layering instead of changing or installing the whole structure again.  To tighten the nails yourself, use a hammer and place the nails between the subfloor and floor joists. Moreover, clean out all the remaining and residues of shims after nailing. Consequently, use a super adhesive for filling the floor gaps and cracks.

Gaps Between Each Floor Layer:

As we mentioned above, nails may lose over time that join the joists and subfloors. In this case, space occurs between the subfloor and the floor surface. These gaps lead to squeaky voices out of the flooring.


 If you want to resolve this issue, you have to consider the following steps:

  • Determine the thickness level of the floor
  • Check the registers and heat indicators by peeling back the metal material to reveal the levels of your floor.
  • If you want to check the thickness level of the floor, use a power drill.
  • You don’t need to drill the holes throughout the surface but only between the upper and subfloor layer.
  • Fill the drilled holes with the screws using the power drill.

The screws will help tighten the floor and bring all layers near to one another. No gaps, no squeaky voices!

Fill The Cracks:

Ideally, filling the floor cracks with the WD-40 is an effortless and quick way to get rid of annoying voices. The best thing is that you don’t require any professional skill to perform this action. All you need to do is use the suitable filler to fill inside the gaps and flooring cracks.

However, it’s not a good option for your floor to use the filler in extreme amounts. If you are doing this, it may damage the whole floor’s surface. But it’s totally okay for all types of wood floor to use the filler in an appropriate amount yourself or with the help of professionals.

Before filling the cracks, it’s better to determine the affected area. So, you can save the other area from unnecessary filling. Keep in mind that you cannot move the boards once you have placed the WD-40. So, set the position of the boards before starting this process.

Does The Noise Occur Because Of Structural Issues?

According to the points discussed above, there are many reasons behind the annoying voices on the floor. So, it’s not accurate to only blame the flooring structure for the squeakiness. Don’t worry; squeaky floors are not dangerous for human beings and the overall flooring surface. But these floors may be irritating for your routine or comfort because of noise popping.

So, you can fix this issue by considering the right solution yourself. However, you can also hire a professional if you don’t know about the flooring structure of your home.


Hopefully, you get the correct answer to your question after reading this article. In short, the structure is not an issue behind the freaking noise of your floor. It may be because of humidity changes, inappropriate floor layers and loose floor joists. Moreover, it also occurs because of gaps and cracks between the floorboards. Now, it’s up to you to choose the right floor repairing option according to your needs and requirements.
