Common mistakes when laying laminate flooring

When it comes to laying laminate flooring, certain mistakes are commonly made that can compromise the overall quality and appearance of the installation. Being aware of these pitfalls is essential to ensure a successful flooring project. This section will explore the most common mistakes when laying laminate flooring and provide valuable insights on avoiding them.

  • Not Purchasing Enough Flooring for the Job: A Costly Oversight

Picture this: midway through your laminate flooring installation, suddenly, you realize you’re running short of material. Panic sets in, accompanied by delays, inconveniences, and the frustrating need to buy additional flooring, often at a higher cost. This scenario is avoidable with careful planning and accurate measurement. Take the time to precisely calculate the square footage of your space, accounting for irregularities and obstacles. Moreover, always purchase good laminate flooring, considering a 10% buffer for waste and future repairs. By doing so, you’ll be well-prepared to tackle your project without unwelcome interruptions.

  • Selecting the Wrong Floor for the Space: A Recipe for Premature Wear

Each space within your home has unique demands, and laminate flooring that thrives in one area may falter in another. Not considering crucial factors such as moisture levels, foot traffic, and subfloor conditions can lead to unsightly wear and premature damage. Before making your flooring selection, carefully assess the specific requirements of your space. Does it experience high humidity or heavy foot traffic? Is it a residential or commercial area? Opt for laminate flooring with an appropriate AC (Abrasion Class) rating that aligns with your space’s usage. By choosing wisely, you’ll ensure a durable and long-lasting floor that will withstand the demands of your environment.

  • Not Sealing Your Floor or Subfloor: Shielding Your Investment

Your laminate flooring is only as strong as the foundation on which it rests. Neglecting to seal your floor or subfloor before installation can pave the way for future headaches. Unwanted moisture can seep through cracks and cause warping or damage to the laminate planks. Before installation, meticulously inspect the subfloor for any signs of moisture or damage, and address these issues accordingly. Applying a moisture barrier and sealing the subfloor will provide an added layer of protection, preserving the integrity and longevity of your laminate flooring.

  • Installing on an Uneven Surface: Setting the Stage for Imperfection

Attempting to install laminate flooring on an uneven surface is akin to building a house on a shaky foundation. The consequences are far from ideal—unstable and squeaky floors, premature wear, and a less-than-flawless finish. Before installation, devote careful attention to leveling the subfloor and rectifying imperfections or irregularities. By diligently preparing the surface, you’ll create a smooth and secure foundation, ensuring the flawless installation of your laminate flooring.

  • Miscalculating the Dimensions of Your Room: Precision Matters

In the realm of laminate flooring installation, precision is paramount. Miscalculating the dimensions of your room can lead to ill-fitting planks, awkward gaps, or excessive waste. To sidestep these pitfalls, take meticulous measurements of your space, considering its square footage and any irregularities or obstacles present. You’ll achieve a seamless installation that exudes visual appeal by meticulously planning the layout and ensuring accurate calculations.

  • Skipping the Instructions: A Shortcut to Subpar Results

Diving headfirst into a laminate flooring installation project is tempting without reading the manufacturer’s instructions. After all, how hard can it be? However, this oversight can prove detrimental. Each brand and product may have specific requirements and guidelines that must be followed for a successful installation. Take the time to peruse and understand the instructions provided by the manufacturer thoroughly. Doing so ensures that every step is executed flawlessly, leaving no room for avoidable errors.

  • Not Checking for Damage: A Potential Blemish in Your Floor’s Perfection

Your laminate flooring is meant to be a visual masterpiece, free from visible defects. Overlooking damaged planks during installation can compromise aesthetics and diminish structural integrity. Before installing, meticulously inspect each laminate plank for any chips, cracks, or other visible imperfections. Set aside any damaged pieces for replacement. By exercising due diligence, you’ll achieve a polished and professional-looking laminate floor that commands attention.

  • Not Leaving a Gap Around Vertical Surfaces: Allowing Your Floor to Breathe

Laminate flooring requires space to expand and contract as temperatures and humidity levels fluctuate. Failing to leave an adequate gap around vertical surfaces, such as walls, door frames, or pipes, can result in unsightly buckling, warping, and a compromised appearance. Ensure the proper installation of your laminate flooring by employing spacers to maintain the necessary expansion gap, typically around 1/4 inch, as the manufacturer recommends. You’ll safeguard your floor’s longevity and preserve its immaculate appearance by giving it the freedom to breathe.

  • Using the Wrong Tools: Equipping Yourself for Success

They say that a skilled craftsman is only as good as their tools, and this adage rings true when laying laminate flooring. Utilizing improper or inadequate tools can lead to damaged planks, uneven cuts, and exasperating installation experiences. Before embarking on your project, ensure you have the necessary tools, including a laminate cutter, tapping block, pull bar, and measuring tape. By arming yourself with the appropriate tools, you’ll execute precise and efficient installation, bringing your vision to life.


Laying laminate flooring can be a gratifying endeavor that adds beauty and value to your home. By familiarizing yourself with the common mistakes when laying laminate flooring outlined in this comprehensive guide, you can confidently navigate the installation process and achieve flawless results. 

Remember to measure your space accurately, select the appropriate laminate flooring for your specific needs, follow the manufacturer’s instructions diligently, and pay meticulous attention to sealing, leveling, and leaving proper expansion gaps. Equipped with the right tools and a meticulous approach, you’ll embark on a journey to create a stunning laminate floor that will stand the test of time. 

Avoiding the pitfalls of common mistakes ensures that your flooring project will be a resounding success, leaving your space transformed and your floors exuding beauty for years to come.


What not to do when laying laminate flooring?

When laying the laminate flooring, it’s crucial to avoid underestimating the material needed, neglecting to seal the floor or subfloor, disregarding instructions, and failing to check for damage. You’ll set the stage for a successful installation by steering clear of these common mistakes.

Does it matter in which direction laminate flooring is laid?

The direction in which laminate flooring is laid can significantly impact the overall aesthetics of a space. As a general guideline, laminate planks are often installed parallel to the longest wall to create a visually pleasing flow. However, the specific layout and direction may vary depending on factors such as room size, shape, and the presence of natural light sources.

Why does my laminate flooring keep separating during installation?

Laminate flooring may separate during installation due to inadequate expansion gaps, uneven subfloors, or improper installation techniques. It’s essential to carefully follow the manufacturer’s instructions, allowing the necessary space for the laminate to expand and contract. Additionally, ensuring a level and well-prepared subfloor is crucial for a secure and flawless installation.

What is a common problem with laminate flooring?

A common issue with laminate flooring is water damage. Although laminate is generally resistant to moisture, excessive exposure to water can cause swelling, warping, and irreversible damage to the planks. Promptly cleaning up spills and avoiding laminate flooring installation in areas prone to high humidity or moisture, such as bathrooms and laundry rooms, can help prevent this common problem.
