Installing laminate flooring can be a rewarding DIY project, but a beautiful, long-lasting result depends on more than just the click-and-lock planks. At Simple Floors Portland, we often see customers come in for advice after a DIY job has gone wrong. Here are the five most common mistakes and how to avoid them for a flawless finish.
1. Skipping the Acclimation Period
This is arguably the most critical and most overlooked step. Laminate flooring, with its wood-based core, is a natural product that reacts to changes in temperature and humidity. When you bring the planks into your home, they need time to adjust.
The Mistake: Unpacking the boxes and installing the planks immediately. The Pitfall: The planks will expand and contract after installation as they adjust to the room's environment, leading to buckling, warping, and unsightly gaps. The Fix: Always follow the manufacturer’s instructions. This typically means leaving the unopened boxes in the room where they will be installed for at least 48 to 72 hours. This simple step allows the material to reach a moisture and temperature equilibrium with its new environment.
2. Neglecting Subfloor Preparation
A beautiful finished floor is only as good as the foundation it's built on. The subfloor must be clean, dry, and perfectly level.
The Mistake: Installing laminate over a bumpy, dirty, or damp subfloor. The Pitfall: Unevenness can cause soft spots, squeaks, and excessive wear on the locking mechanism, leading to premature failure. Dust and debris can scratch the underside of the planks, and moisture can cause mold growth or warping. The Fix: Before you begin, sweep and vacuum the entire subfloor. Use a long level or straightedge to check for any high or low spots. Sand down high points and fill in low spots with a leveling compound. Also, perform a moisture test and use a proper moisture barrier if needed.
3. Not Using the Right Underlayment
The underlayment is an unsung hero of a successful laminate installation. It's a thin layer that goes between the subfloor and the laminate.
The Mistake: Using the wrong underlayment or skipping it altogether. The Pitfall: The wrong underlayment can lead to poor sound insulation, a lack of moisture protection, and a hollow sound underfoot. The Fix: Choose an underlayment designed for laminate flooring. It provides cushioning, deadens sound, and acts as a moisture barrier. Many modern laminates come with an attached pad, but for others, a separate underlayment is a must.
4. Failing to Leave an Expansion Gap
Laminate flooring is a "floating" floor system, meaning it’s not attached to the subfloor or walls. It needs room to expand and contract freely with changes in humidity.
The Mistake: Cutting the planks to fit snugly against the walls, baseboards, or other fixed objects. The Pitfall: When the planks expand, they have nowhere to go. This "pressure" causes the floor to buckle, tent, or lift away from the subfloor. The Fix: Leave a consistent expansion gap of about ⅜ of an inch around the entire perimeter of the room. This includes along walls, at doorways, and around columns. Use spacers during installation to maintain this gap, which will later be covered by baseboards or quarter-round molding.
5. Improperly Staggering Planks
While this mistake won't cause structural damage, it will make your floor look unprofessional.
The Mistake: Laying planks with the end joints aligned or in a repetitive, "H" pattern. The Pitfall: This creates a manufactured, unnatural look and can weaken the structural integrity of the floor. The Fix: Stagger your planks randomly and ensure that the end joints of adjacent rows are at least 6 inches apart. A good rule of thumb is to use the offcut from the previous row to start the next row.
By following these simple guidelines, you can avoid the most common installation mistakes and achieve a professional, long-lasting laminate floor you can be proud of. If you have any questions or need a helping hand, our experts at Simple Floors Portland are always here to help.
