Why is My Laminate Floor Bubbling? Causes, Prevention, and Solutions

Laminate flooring is a popular choice for homeowners due to its affordability, durability, and the wide range of designs that mimic natural wood or stone. However, one issue that can arise with laminate flooring is bubbling. If you’ve noticed your laminate floor bubbling, it’s crucial to address the problem promptly to prevent further damage. 

Understanding Laminate Floor Bubbling

Laminate floor bubbling occurs when parts of the flooring rise or swell, creating uneven surfaces. This bubbling effect not only detracts from the aesthetic appeal of your floor but can also be a sign of underlying problems that need immediate attention. Bubbling can happen for various reasons, but the most common culprit is moisture. However, improper installation and wear and tear over time can also contribute to this issue.

Common Causes of Laminate Floor Bubbling

1. Moisture and Water Damage

One of the primary causes of laminate floor bubbling is moisture. Laminate flooring is made up of layers, including a core layer of high-density fiberboard (HDF) that is susceptible to water damage. 

When water penetrates the seams of the laminate, it causes the core to swell, leading to bubbling. This moisture can come from spills, leaks, or high humidity levels in the room. If your laminate flooring is installed in areas prone to moisture, such as kitchens, bathrooms, or basements, it’s at a higher risk for bubbling.

2. Poor Installation Practices

Another common reason for laminate floor bubbling is improper installation. Laminate flooring needs room to expand and contract with changes in temperature and humidity. If the flooring is installed too tightly against the walls or without adequate expansion gaps, it can buckle and bubble as it tries to expand. 

Additionally, using the wrong underlayment or not allowing the laminate to acclimate to the room’s temperature before installation can also result in bubbling.

The gap between the two laminate tiles indicates it was improperly installed. 

3. Subfloor Issues

Problems with the subfloor can also lead to bubbling in your laminate flooring. If the subfloor isn’t level, or if it has moisture issues, the laminate can rise in certain areas. Additionally, if the subfloor material is not compatible with laminate flooring or if there are gaps and cracks, these can all contribute to the bubbling effect.

4. Temperature Fluctuations

Laminate flooring is sensitive to temperature changes. Extreme heat can cause the laminate to expand, while cold temperatures can make it contract. If the flooring is not installed with proper expansion gaps, these temperature fluctuations can cause the floor to buckle and bubble. It’s essential to maintain a stable indoor climate to avoid these issues.

5. Heavy Furniture and Impact Damage

Placing heavy furniture directly on laminate flooring without protective padding can lead to bubbling over time. The weight can compress the laminate layers, and if moisture seeps in, it can worsen the problem. Additionally, dropping heavy objects on the floor can cause impact damage, which might lead to bubbling in that area.

Preventing Laminate Floor Bubbling

Prevention is key when it comes to maintaining your laminate flooring and avoiding issues like bubbling. Here are some tips to help you prevent laminate floor bubbling:

1. Control Moisture Levels

To prevent moisture-related bubbling, it’s essential to control the humidity levels in your home. According to the Environmental Protection Agency, indoor relative humidity should be below 60 percent and ideally between 30 and 50 percent.

Use a dehumidifier in areas prone to high humidity, such as basements or bathrooms. Clean up spills immediately, and avoid using excessive water when cleaning your laminate flooring. Ensure that any leaks, whether from appliances or plumbing, are promptly fixed to prevent water from seeping into the laminate.

A dehumidifier helps remove moisture from your room, which can help your laminate floor. 

2. Proper Installation

Ensuring that your laminate floor is installed correctly is one of the best ways to prevent bubbling. Ensure that the flooring is installed with the proper expansion gaps around the edges to allow for natural movement. 

It’s also crucial to use the correct underlayment and to allow the flooring to acclimate to the room’s temperature before installation. Hiring a professional to install your laminate flooring can help ensure that it’s done correctly.

3. Choose the Right Laminate for the Area

When choosing laminate flooring, consider the specific area where it will be installed. Some laminate options are more water-resistant than others and are better suited for areas like kitchens or bathrooms. Selecting the right laminate for high-moisture areas can help reduce the risk of bubbling.

4. Protect Your Flooring

Use furniture pads under heavy furniture to distribute weight evenly and prevent compression of the laminate. Additionally, avoid dragging furniture across the floor, as this can cause damage. Place rugs in high-traffic areas to reduce wear and tear, and be cautious when moving heavy objects.

Placing a pad on your furniture helps protect your flooring.

5. Regular Maintenance

Regular maintenance is crucial in preventing issues like bubbling. Keep your laminate floor clean and dry, and avoid using harsh chemicals that can damage the surface. Inspect your flooring regularly for signs of bubbling or other damage, and address any issues promptly to prevent them from worsening.

What to Do When Your Laminate Floor is Bubbling

If you’ve already noticed bubbling in your laminate flooring, it’s important to take action to prevent further damage. Here’s what you can do:

1. Identify the Source of Moisture

The first step is to identify and eliminate the source of moisture causing the bubbling. This could be a leak, high humidity, or a spill that wasn’t cleaned up promptly. Addressing the moisture issue is crucial to preventing further bubbling.

2. Repair or Replace Affected Areas

Depending on the extent of the damage, you may need to repair or replace the affected areas of your laminate flooring. For minor bubbling, you might be able to fix the issue by placing a heavy object on the bubbled area to flatten it out. However, if the damage is severe, you may need to replace the affected planks. It’s important to follow the manufacturer’s guidelines for repairs to ensure the best results.

3. Consult a Professional

If you’re unsure about how to address the bubbling or if the damage is extensive, it’s best to consult a professional. They can assess the situation and recommend the best course of action, whether it’s repairing or replacing the affected areas or addressing underlying issues with the subfloor.

Laminate floor bubbling is a common issue that can be caused by various factors, including moisture, poor installation, and temperature fluctuations. By understanding the causes and taking preventive measures, you can protect your laminate flooring from bubbling and ensure it remains in good condition for years to come.
