Common Mistakes When Laying Laminate Flooring


When it comes to home renovation projects, laying laminate flooring is a popular choice for many homeowners. Laminate flooring offers durability, affordability, and a wide range of design options. However, it’s important to be aware of the common mistakes that can occur during the installation process. In this article, we will explore the most frequent errors made when laying laminate flooring and provide expert advice on how to avoid them. Whether you’re a DIY enthusiast or a professional contractor, this guide will help you achieve a flawless laminate flooring installation.

Here are the Common Mistakes When Laying Laminate Flooring

Laying laminate flooring may seem like a straightforward task, but there are several common mistakes that can lead to unsatisfactory results. By understanding these mistakes and taking the necessary precautions, you can ensure a successful and visually appealing installation.

Insufficient Subfloor Preparation

One of the most crucial steps when laying laminate flooring is preparing the subfloor. Failing to adequately prepare the subfloor can result in uneven surfaces, squeaky floors, and premature wear and tear. Before installation, it’s essential to ensure that the subfloor is clean, dry, and level. Remove any debris, repair any cracks or imperfections, and ensure that the subfloor is free from moisture.

Poor Acclimation of Laminate Flooring

Proper acclimation of laminate flooring is often overlooked but is vital to prevent issues such as buckling and gaps. Laminate flooring needs time to adjust to the temperature and humidity of the installation environment. Neglecting to acclimate the flooring can cause it to expand or contract after installation, leading to significant problems. Follow the manufacturer’s guidelines for acclimation, which typically involve leaving the flooring in the room for a specific period before installation.

Incorrect Expansion Gap

Laminate flooring expands and contracts with changes in temperature and humidity. To accommodate these movements, it’s crucial to leave an expansion gap around the perimeter of the room. This gap allows the flooring to shift without buckling or warping. Failing to provide an adequate expansion gap is a common mistake that can result in unsightly gaps, distorted planks, and even damage to the flooring.

Using the Wrong Underlayment

Underlayment plays a vital role in the performance and longevity of laminate flooring. It provides moisture protection, sound insulation, and helps to smooth out minor imperfections in the subfloor. Using the wrong type or thickness of underlayment can lead to various problems. For instance, using an underlayment that doesn’t provide sufficient moisture protection can cause damage to the flooring over time. Always follow the manufacturer’s recommendations for the appropriate underlayment for your specific laminate flooring product.

Incorrect Installation of Underlayment

Even if you choose the right underlayment, incorrect installation can undermine its effectiveness. Common mistakes include overlapping seams incorrectly, failing to secure the underlayment properly, or using inappropriate fasteners. These errors can lead to a compromised underlayment, reducing its ability to provide the desired benefits. Always carefully read the installation instructions provided by the manufacturer and follow the recommended installation techniques.

Poor Cutting and Measuring Techniques

Accurate cutting and measuring are essential for a professional-looking laminate flooring installation. Cutting planks too short or too long can result in uneven gaps and an unattractive finish. Using improper tools or techniques can also lead to chipped edges or damaged planks. Take the time to measure and mark each plank carefully before making any cuts. Use appropriate tools such as a laminate cutter or a circular saw with fine-tooth blades for laminate flooring for clean and precise cuts.

Neglecting to Stagger Planks

Staggering the planks during installation is crucial to achieving visually appealing and structurally sound laminate flooring. Failing to stagger the planks can result in weak points and an unnatural, repetitive pattern. Follow the manufacturer’s instructions regarding the recommended stagger pattern, typically involving starting each new row with a plank cut to a specific length. This technique ensures the stability and integrity of the flooring while creating an aesthetically pleasing layout.


Avoiding common mistakes when laying laminate flooring is essential for achieving a successful and visually appealing installation. By properly preparing the subfloor, ensuring proper acclimation, leaving an adequate expansion gap, using the right underlayment, and following correct cutting and measuring techniques, you can avoid many potential issues. Additionally, staggering planks and addressing frequently asked questions about laminate flooring installation further contribute to a seamless and professional finish. Remember to follow manufacturer guidelines, take your time, and prioritize accuracy for a long-lasting and beautiful laminate flooring installation in your home.
