Wooden staircases add coziness and elegance to a home, but over time they can begin to make unpleasant creaking noises with every step. Not only are these sounds annoying, but they can also indicate structural problems that need attention. So why do wooden stairs start to creak and what can be done to fix the problem?

In this article, we'll look at the main causes of creaking in wooden stairs, including fastener wear, wood shrinkage, and other factors. We'll also offer practical tips and techniques to help you deal with this nuisance. Learn how to get your stairs back to quiet and sturdy by following our recommendations and professional advice.

The main causes of staircase creaking

Shrinkage

Wood shrinkage is one of the most common causes of wooden stairs squeaking. Wood tends to change its dimensions depending on moisture levels and temperature. Over time, it can shrink and expand, which leads to gaps between the elements of the structure and, as a result, to squeaking.

Wear over time and deformation

Natural wear and warping of wood occurs over time due to the constant use of the staircase. Gradual abrasion of the surfaces and disruption of the original joints can cause squeaks. Wood can also warp due to stresses and changes in the microclimate of the room.

Insufficient fastening

Insufficient fastening of steps, treads or railings can also cause squeaking. If the fixing elements are loose or installed incorrectly, when walking, there are movements of parts of the stairs, which lead to the appearance of squeaks.

Fitting errors

Errors in the manufacture and installation of stairs, such as improper fitting of parts, can cause squeaks. Uneven or poorly fitted joints create unnecessary gaps and stresses in the structure, which leads to sound effects under load.

Floor deflection

Sagging of the floor base under the stairs can be an additional cause of squeaks. If the floor is not sufficiently rigid and stable, the movement of the staircase causes distortion and friction, which causes unpleasant sounds. Fixing the deflection and reinforcing the base of the floor will help solve this problem.

Understanding the main causes of wooden staircase squeaking will help you determine the most effective methods of eliminating this unpleasant phenomenon. In the next section, we'll look at what you can do to eliminate squeaks and restore comfort to your home.

What can be done?

Repair the steps

The first step in eliminating the squeaking of a wooden staircase is to repair the steps. To do this, the following steps can be performed:

• Tighten the fasteners: Make sure that all step fasteners are tightened and secure. Use a instruments to tighten screws and nails.
• Fixing gaps: If there are gaps between the steps and treads, use wooden wedges or a special sealant to fill the gaps. This will prevent movement and friction of the parts.
• Replacing damaged elements: If the steps or treads are badly worn or damaged, replace them with new elements. This will ensure that the structure is secure and sturdy.

Checking the connections of the supporting structures

An equally important step is to check the connections of the supporting structures of the staircase. Here are a few recommendations:

• Inspect and reinforce the fasteners: Check all the main fasteners of the staircase, including connections to beams and walls. If necessary, reinforce them with additional fasteners or metal brackets.
• Fitting of parts: Make sure that all parts of the staircase fit together correctly. If you find any irregularities or gaps, use sanding tools to remove them.
• Using glue: You can use carpenter's glue to strengthen the joints. Apply it to the joints where the pieces meet and securely fasten them together.
• Reinforcing the floor base: If the problem is related to floor deflection under the stairs, consider reinforcing the floor. This may include installing additional joists or reinforcing existing joists.

These measures can greatly reduce or completely eliminate wooden staircase creaking, ensuring comfort and quietness in your home. If you can not cope with the problem on your own, it is recommended to contact professionals for a more detailed inspection and quality repair.

Seasonal creaking

Creaking stairs can be caused not only by defects in parts and their connections, but also by the impact of environmental factors. Wood absorbs atmospheric moisture well, so at high humidity in the air the parts increase in volume, which leads to the formation of gaps and weakening of connections. This causes creaking, which can come and go depending on the season.

To prevent this effect, you can apply a hydrophobizer to wood surfaces. It will reduce moisture absorption and stabilize the dimensions of the wooden parts.

Another way to eliminate seasonal squeaking is to treat the mating planes with paraffin or silicone sealant. This procedure should be carried out at low humidity. After applying the sealant, the staircase should not be used for 1-2 days, until the composition is completely hardened.

Additional recommendations:

• To slow down the wear and deformation of parts, you can install damping pads from elastic material in places where they touch.
• It is better to repair the steps under a load equal to the average weight of a person.
• In the staircase structures installed on the three Kosoûr, the greatest wear is subjected to the central Kosoûr. You can eliminate the squeak by fixing the steps in the central part with metal fasteners or glue.

These measures will help minimize the seasonal creaking of the stairs and preserve its durability.
