Buckled Laminate Flooring: How to Prevent Laminate Floors from Buckling

What Is Laminate Floor Buckling?

Laminate floor buckling is an uneven appearance caused by planks lifting and splitting. This can be a very unsightly problem, resulting in raised ridges on affected laminate floors. A variety of factors, including moisture, temperature changes, and improper installation can cause it. Moisture and water damage are the most common causes of buckling, as they can cause the planks to swell and lift up from the subfloor. Temperature changes can also cause buckling due to the expansion and contraction of the laminate planks. An improper installation such as not allowing for proper acclimation or not leaving an expansion gap between the walls and flooring can also lead to buckling. Buckling is most common near walls where the expansion of the laminate flooring has been restricted.

How to Prevent Laminate Floors from Buckling

Reasons Your Laminate Floor Is Buckling

Laminate flooring buckling is a common issue that can be caused by a variety of factors. Buckling is most likely to occur near walls where the laminate flooring expansion has reached its maximum capacity. Improper acclimation, lack of an expansion gap, high or low room temperature, and no vapour barrier can all contribute to buckling in laminate floors.

Moisture and Temperature Changes

Moisture and temperature changes can have a significant impact on laminate flooring. When moisture levels increase, the laminate floorboards can expand, separate, warp, buckle or lift. This is especially true when there is flooding or water leaks in the home. Poor cleaning practices such as wet mopping or steam cleaning can also push water into the core of the laminate flooring and cause damage. Additionally, humidity variation in the house due to temperature changes can cause swelling and other issues with the laminate flooring.

It is important to take steps to protect your laminate flooring from moisture. Make sure that any potential sources of water are addressed immediately and that you use simple cleaning techniques when caring for your floors. Additionally, it may be beneficial to invest in a dehumidifier to help regulate humidity levels in your home. Taking these precautions will help ensure that your laminate flooring remains in good condition for years to come.

Improper Installation

Improper installation of laminate flooring can lead to a variety of problems, such as buckling, lifting, or warping. This is often caused by humidity in the room, which causes the laminate boards to expand and press against each other and the wall. As a result, bubbling on the floor or swollen laminate flooring may occur. Additionally, it is important to choose the right type of laminate flooring for rooms exposed to moisture as using the wrong variety can cause buckling.

To ensure the proper installation of laminate flooring, it is important to follow all instructions carefully and use the correct tools and materials. It is also essential to measure twice before cutting any boards and leave enough space between walls and furniture for expansion. Additionally, it is important to check that there are no gaps between laminate boards where water could seep in and cause damage. These steps will help ensure that your laminate flooring is properly installed and remains in good condition for years to come.

Subfloor Imperfections and Problems

Subfloor imperfections can cause a variety of problems with laminate flooring. An uneven surface can lead to the laminate floor lifting, whereas moisture barrier and proper underlayment play a major role in preventing moisture accumulation and buckling of the floor.

It is important for homeowners to be aware of potential subfloor imperfections and take steps to prevent them from occurring. Regular inspections should be conducted on both the subfloor and laminate flooring in order to identify any issues before they become too severe. If moisture damage has occurred, it is essential that it be addressed as soon as possible in order to avoid further damage or costly repairs.

Why Is My Laminate Flooring Buckling

How to Repair Buckled Laminate Flooring

Buckled laminate flooring is a frustrating problem for homeowners. It often seems to happen overnight and can cause the entire floor to become uneven and unsightly. In order to repair the buckled laminate floor, it is important to first determine the underlying issue causing the buckling. This could involve repairing any damage to the subfloor or replacing any damaged laminate planks with new ones. Additionally, using a humidifier to maintain humidity levels in your home can help prevent future buckling.

Once you have identified and fixed the cause of the buckling, you can begin replacing the damaged planks. Ashley’s blog post about her experience with kitchen cabinets and flooring mistakes to avoid provides a great outline for how to replace laminate floor planks correctly. This includes ensuring that all boards are level before securing them into place and using a floor roller to ensure that the entire floor is even and secure. With proper care and maintenance, your laminate floors should remain in good condition for years to come!

Replacing a Damaged Laminate Floor

Replacing a damaged laminate floor can be a daunting task, but with the right tools and knowledge, it can be done. The first step is to identify the area of damage and remove any moulding closest to it. Once this is done, you can begin replacing the damaged laminate planks with boards from a new batch, locking them as you proceed to the moulding. It is important to use high-grade laminate with a built-in moisture barrier when selecting new flooring and consider hiring a professional to install the planks properly with an expansion gap to prevent damage. To ensure that the planks are firmly set, tap them with a hammer and wood block. For more extensive damage, you may need to see off the affected part with a circular saw and tape for a more complex solution. Finally, make sure to order surplus quantities of flooring material so that you don’t have to order another batch if something goes wrong during installation. With these steps in mind, you can successfully replace your laminate floor and prevent future buckling.


To reduce buckling, it is important to avoid excessive moisture by using a dehumidifier and cleaning up spills quickly. Mats or rugs at entryways can also help reduce dirt and debris that can cause buckling. Additionally, heavy furniture should be placed on felt pads to prevent it from scratching the floor and causing buckling. Finally, it is important to check the manufacturer’s instructions for any additional tips or precautions that should be taken.
