What Causes Laminate Flooring To Bubble? (Explained)

Laminate flooring is a popular choice for many homeowners due to its attractive appearance, affordability, and durability. Yet, as a flooring contractor with years of experience, I’ve encountered one particular issue that can lead to frustration: bubbling in laminate floors. This phenomenon can be alarming for homeowners and often raises questions about its causes and solutions. In this article, I will share my personal experiences, insights, and tips regarding what causes laminate flooring to bubble, how to fix it, and how to prevent it from happening in the first place.

The Functionality of Laminate Flooring

What I love about laminate flooring is its functionality. It mimics the look of hardwood or stone without the hefty price tag. Plus, it’s resistant to scratches and stains, making it ideal for busy households. However, despite its overall resilience, laminate flooring can experience problems like bubbling if certain precautions are not taken.

Bubbling can occur due to various reasons, and understanding these factors is crucial for anyone looking to install or maintain laminate flooring. Let’s explore the potential causes of bubbling in laminate flooring more closely.

Causes of Bubbling in Laminate Flooring

Moisture Intrusion

Moisture is arguably the most significant factor in the bubbling of laminate flooring. Laminate is constructed from multiple layers, including a core board that can absorb moisture. When water seeps into the core layer, it can cause the boards to swell and create bubbles on the surface.

I remember working on a lovely kitchen remodel where the homeowners had chosen a beautiful laminate flooring option. Unfortunately, they hadn’t sealed the edges properly before installation. After a few weeks, they noticed bubbles forming near the dishwasher due to a small leak. It was a painful lesson in moisture management.

To avoid moisture-related issues, always ensure that any potential sources of water are addressed before installation. Using moisture barriers is essential when installing laminate in areas prone to spills or high humidity.

Poor Installation Techniques

Another common cause of bubbling is poor installation practices. When I first started my career as a flooring contractor, I made my fair share of mistakes. One critical error was not allowing laminate planks to acclimate to the room’s humidity and temperature before installation.

Imagine setting up a beautiful floor only for it to bubble up within weeks because the boards were ill-prepared for their new environment! I recall one specific job where I installed laminate flooring in a newly built home during winter. The outside temperature was far lower than the indoor conditions. The laminate planks were cold and rigid when they were installed, leading to bubbling once they warmed up inside.

To avoid this problem, always allow laminate planks to acclimate for at least 48 hours in the room they will be installed. This step helps ensure that the material adjusts to its new environment.

Insufficient Expansion Gaps

Laminate flooring expands and contracts with changes in temperature and humidity levels. If there aren’t adequate expansion gaps around the room’s perimeter, pressure can build up as the flooring expands, leading to bubbling.

I’ve seen this firsthand when working on installations where I didn’t leave enough space between the flooring and fixed objects like walls and door frames. In one case, I had completed a living room installation but neglected to leave a sufficient gap around the edges. As temperatures fluctuated due to heating systems being turned on and off, bubbles began to appear near the walls.

To prevent this issue, I now ensure there’s at least a ¼ inch gap around all edges of the laminate flooring. This little detail can save you from significant headaches down the line.

Low-Quality Materials

Using low-quality laminate materials can also contribute to bubbling. Some manufacturers cut corners during production, leading to weaker core boards that are more susceptible to moisture damage and swelling.

I’ve worked with various brands over the years. Some cheaper options initially seem appealing due to their low price point, but they often lead to issues later on, including bubbling and warping. Investing in higher-quality materials pays off in terms of longevity and reliability.

How to Fix Bubbling Laminate Flooring

If you find yourself facing bubbling laminate flooring, don’t stress; there are several methods to address this issue based on its severity.

Minor Bubbles

For minor bubbles that haven’t caused significant damage, you might be able to fix them simply by applying weight over the affected area. I’ve used heavy books or bricks placed on top of small bubbles for a few days. This technique can sometimes help flatten out minor bubbles caused by temporary moisture exposure.

Significant Bubbling

If you’re dealing with significant bubbling due to moisture intrusion or improper installation, you may need to take more drastic actions. In one instance, I had to lift sections of flooring to dry out the underlayment after discovering extensive bubbling caused by a hidden leak.

This process took about two days and involved removing damaged planks. After drying out the underlayment thoroughly, we replaced any affected planks before reinstalling everything correctly.

Maintenance Tips To Prevent Bubbling

Preventing bubbling is much easier than fixing it later. Here are some tips based on my experience:

  • Regular Cleaning: Keep your laminate flooring clean and avoid excessive water when mopping. A damp mop is best for maintaining cleanliness without risking moisture damage.
  • Use Rugs Strategically: In high-traffic areas or near water sources like sinks or dishwashers, consider using rugs or mats to catch spills before they reach your laminate.
  • Monitor Humidity Levels: If you live in an area with high humidity, invest in a dehumidifier to keep moisture levels under control.
  • Seal Edges Properly: When installing laminate in moisture-prone areas, make sure to seal edges thoroughly with caulk or sealant.

Cost Estimation With FloorTally

Budgeting for laminate flooring projects can be challenging, but tools like FloorTally have made my job much easier over the years. This platform allows me to pull local material and labor rates accurately.

For instance, during a recent project for a 1,200 square foot installation in suburban Chicago, I was able to determine realistic costs using FloorTally’s features. Typically, laminate materials run around $3-$5 per square foot. But with FloorTally’s assistance, I was also able to include costs for waste management and labor accurately.

Having an accurate estimate upfront helps me communicate better with clients and ensures there are no surprises later on when it comes time to settle the bill.

Comparing Different Laminate Options

Over my years in this industry, I’ve experimented with numerous laminate brands and types. Some have performed better than others concerning durability and resistance to bubbling.

  • Standard Laminate: While these are cost-effective choices for many projects, they tend to be more prone to bubbling if exposed to moisture.
  • Water-Resistant Laminate: This type has gained popularity among my clientele due to its added protection against moisture damage—ideal for kitchens and bathrooms.
  • High-Quality Brands: Brands like Pergo or Quick-Step have proven themselves over time with better warranties and robust construction methods that minimize issues like bubbling.

Technical Specifications

When selecting laminate flooring, it’s crucial to consider its specifications:

  • AC Rating: This rating indicates durability; an AC3 rating is suitable for residential use while AC4 or AC5 can handle commercial settings.
  • Thickness: Generally speaking, thicker planks (12mm or more) perform better regarding sound absorption and stability.
  • Locking Mechanism: A strong locking system helps prevent gaps and misalignment that lead to bubbling.

Personal Anecdotes: Successes and Challenges

Throughout my career as a flooring contractor, I’ve encountered numerous successes and challenges related to laminate flooring installations and maintenance.

For example, I once completed an installation for a young couple who had just purchased their first home. They wanted a stylish yet durable floor that could withstand their busy lifestyle with pets and children. We chose a high-quality water-resistant laminate option that not only fit their aesthetic preferences but also provided added durability against spills and scratches.

This project turned out beautifully! Their excitement upon seeing their new living room floor was incredibly rewarding. They later reported no issues with bubbling even after several years of use.

However, not every job goes smoothly. I remember another project where I didn’t realize until too late that the existing subfloor was uneven. After installing the laminate flooring, we discovered several bubbles forming due to pressure points caused by the uneven surface beneath. We had to remove sections of the flooring and level out the subfloor before reinstallation—a frustrating setback that extended the project timeline by several days.

Practical Information About Usage

Maintaining laminate flooring doesn’t have to be complicated if you follow some basic guidelines:

  1. Avoid Excessive Water: When cleaning your floors, always use a damp mop instead of soaking wet cloths.
  2. Use Appropriate Cleaners: Make sure you’re using cleaners specifically designed for laminate surfaces—avoid harsh chemicals that can damage the finish.
  3. Address Spills Immediately: Promptly clean up spills using a dry cloth or a damp cloth followed by drying the area thoroughly.
  4. Protect Against Scratches: Use felt pads under furniture legs and avoid dragging heavy items across the floor.

Conclusion: Making Informed Choices

Bubbling in laminate flooring can be frustrating but understanding its causes enables you to take preventive measures effectively.

By investing time upfront in proper installation techniques—like allowing acclimation time, ensuring sufficient expansion gaps, and choosing high-quality materials—you can significantly reduce the chances of encountering issues down the road.

As I’ve learned throughout my journey as a contractor, utilizing tools like FloorTally for accurate cost estimates has made budgeting more accessible while ensuring transparency with clients regarding expenses.

If you’re faced with bubbling or other issues related to your laminate flooring, remember that solutions exist! With careful attention and preventive measures taken during installation and maintenance phases alike—you can keep your floors looking beautiful for years to come.
