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

Laminate flooring is a popular choice for homeowners in Suffolk and Nassau counties due to its affordability, durability, and the wide range of designs that mimic natural wood or stone. However, the region’s humid subtropical climate, characterized by warm summers and significant precipitation, can pose challenges such as laminate floor bubbling. Understanding the causes and implementing preventive measures is essential to maintain the longevity and appearance of your flooring.

Understanding Laminate Floor Bubbling

Laminate floor bubbling occurs when sections of the flooring rise or swell, creating uneven surfaces. This not only detracts from the floor’s aesthetic appeal but also indicates underlying issues that require immediate attention. In Suffolk and Nassau counties, the primary causes include moisture intrusion, improper installation, and temperature fluctuations.

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.

  1. 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.

  1. Subfloor Issues

An uneven or moisture-compromised subfloor can lead to bubbling. If the subfloor isn’t level or has moisture problems, the laminate may rise in certain areas. Ensuring the subfloor is dry, level, and compatible with laminate flooring is crucial to prevent such issues.

  1. Temperature Fluctuations

Suffolk and Nassau counties experience a range of temperatures throughout the year. Laminate flooring is sensitive to these fluctuations; extreme heat can cause expansion, while cold can lead to contraction. Without proper expansion gaps, these changes can result in buckling and bubbling. Maintaining a stable indoor climate helps mitigate this risk.

  1. Heavy Furniture and Impact Damage

Placing heavy furniture directly on laminate flooring without protective padding can compress the layers, leading to bubbling, especially if moisture is present. Dropping heavy objects can also cause localized damage and bubbling.

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.

  1. 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.

  1. Choose the Right Laminate for the Area

Select laminate flooring designed to withstand higher moisture levels for areas like kitchens, bathrooms, or basements. Some products offer enhanced water resistance, making them more suitable for such environments

  1. Protect Your Flooring

Use furniture pads under heavy items to distribute weight evenly and prevent compression. Avoid dragging furniture across the floor, and place rugs in high-traffic areas to reduce wear and tear.

  1. Regular Maintenance

Keep your laminate flooring clean and dry. Avoid using excessive water or harsh chemicals during cleaning. Regularly inspect for signs of bubbling or damage and address issues promptly to prevent escalation.

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.

  1. 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.

  1. 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.
