Just make sure to leave the repair of tongue-and-groove hardwood flooring to the professionals. By following a few tips to avoid future buckling, you’ll not only maintain the value of your home but also potentially increase its selling price.

Signs of Buckled Hardwood Flooring

Cracks

One of the signs that your hardwood flooring may be buckled is the presence of cracks. These cracks can occur in various sizes and shapes, and they are a clear indication that something is wrong with your floor.

Cracks can form when the wood expands and contracts due to excess moisture, causing it to buckle and shift. If you notice cracks in your hardwood floor, it is important to address the issue as soon as possible to prevent further damage.

Cupped Edges

Another sign of buckled hardwood flooring is cupped edges. Cupping occurs when the edges of the floorboards are higher than the center, creating a concave shape. This can be an indication that moisture has been absorbed into the wood, causing it to swell and buckle.

Cupping can occur due to excess moisture accumulation or water damage. If you notice cupping on your hardwood floor, it is essential to identify and address the underlying problem to prevent further damage.

Crowning

Crowning is the opposite of cupping and occurs when the center of the floorboards is higher than the edges. This can create a hump-like appearance on the surface of the floor.

Crowning can also be caused by excess moisture accumulation or water damage, leading to the wood expanding and pushing against each other. If you notice crowning on your hardwood floor, it is crucial to take immediate action to prevent further damage and restore the floor to its original condition.

Lifting

One of the most noticeable signs of buckled hardwood flooring is lifting. Lifting occurs when the floorboards become detached from the subfloor and rise above its surface. This can create an uneven and unstable floor, making it unsafe to walk on.

Lifting can be caused by excess moisture accumulation or water damage, which weakens the adhesive holding the floorboards in place. If you experience lifting in your hardwood floor, it is essential to address the issue promptly to prevent accidents and restore the floor’s stability.

Causes of Buckled Hardwood Flooring

Excess Moisture Accumulation

Excess moisture accumulation is one of the primary causes of buckled hardwood flooring. When wood absorbs too much moisture, it expands and can no longer fit within the space it was installed.

This leads to buckling, as the wood pushes against the neighboring boards and the subfloor.

Excess moisture can come from a variety of sources, such as high humidity levels, poor ventilation, or water leaks. It is important to control the moisture levels in your home to prevent this issue from occurring.

Water Damage

Water damage is another common cause of buckled hardwood flooring. This can occur when the floor is exposed to water for an extended period of time, causing the wood to swell and warp.

Water damage can happen due to various reasons, including plumbing leaks, overflowing toilets, or burst pipes. It is crucial to fix any water-related issues promptly to prevent damage to your hardwood floor.

Flooding

Flooding is an extreme form of water damage that can result in severe buckling of hardwood flooring. When a significant amount of water enters your home, it can quickly saturate the wood, causing it to absorb excessive moisture.

This rapid and excessive swelling can lead to significant buckling and damage to the floorboards. If your home experiences flooding, it is essential to dry out the affected area and assess the extent of the damage as soon as possible.

Gradual Moisture Build-Up

In addition to excess moisture accumulation and water damage, gradual moisture build-up can also cause hardwood flooring to buckle. This can happen over time if there are small and continuous water leaks in your home.

The constant exposure to moisture can lead to the gradual expansion of the wood, eventually causing it to buckle and warp. It is important to regularly check for any signs of water leaks and address them promptly to avoid long-term damage to your hardwood floor.

Poor Acclimation

Another cause of a buckled wood floor is poor acclimation. Acclimation refers to the process of allowing the wood floor to adjust to its new environment before installation. If the wood is not properly acclimated, it can expand or contract after installation, leading to buckling.

It is crucial to store the wood flooring in a space with similar conditions to where it will be installed to ensure it absorbs or disperses its moisture until it is “equal” to the surrounding air. This allows the wood to get used to its environment and prevents buckling.

Poor Installation

Improper installation can also cause a wood floor to buckle over time. For nail-down floors, incorrect subfloor construction or inadequate nailing can lead to buckling. For glue-down floors, insufficient or incorrect adhesive, as well as subfloor contamination or separation, can cause buckling.

Additionally, if the expansion gap left around the room’s perimeter is not large enough, the wood floor can start to buckle. The expansion gap is crucial for proper wood flooring installation, as it allows the planks to expand when the room humidity increases. Inadequate expansion gaps can result in buckling.

Repairing Buckled Hardwood Flooring

If you notice signs of buckled hardwood flooring in your home, it is crucial to take action and repair the issue to prevent further damage and restore the integrity of your floor. The following are steps you can take to repair buckled hardwood flooring:

Removing Excess Moisture

The first step in repairing buckled hardwood flooring is to remove excess moisture from the affected area. This can be done by using towels or a vacuum cleaner to soak up any standing water.

After removing the excess moisture, you can use an electric fan or open windows to increase airflow and aid in the drying process. It is important to thoroughly dry the area before proceeding with any repairs.

Replacing Damaged Boards

Once the excess moisture has been removed, you can proceed with replacing the damaged boards. Start by using a circular saw to cut along the length of the buckled boards. Be careful to only cut through the damaged area and not the surrounding floorboards.

After making the cuts, use a pry bar to carefully remove the damaged boards from the subfloor. Once removed, use a chisel and hammer to clean up the edges and prepare them for the replacement planks.

Finally, install the replacement planks using flooring adhesive or nails, ensuring a secure fit. Allow the adhesive to dry completely before walking on the repaired area.
