Can You Put Laminate Flooring on an Uneven Floor?

Laminate flooring is a popular and cost-effective choice for many homeowners, admired for its durability, low maintenance, and the wide range of styles it offers.

Yet, its requirements must be met for a successful installation, including a level surface. As someone with experience with this, I can attest to the importance of a flat surface.

Once, in my eagerness to update my home, I overlooked a slight dip in the floor of my living room. The result? A laminate floor that creaked ominously with every step and required a complete do-over.

This ordeal taught me, and I hope to impart to you, that the effort spent in ensuring a level surface far outweighs the inconvenience of dealing with an uneven laminate floor.

This blog post will explore whether you can lay laminate flooring on an uneven floor and provide guidance on preparing your floor for laminate installation.

Understanding Laminate Flooring

To truly understand why level flooring is crucial when installing laminate, we first need to grasp what laminate flooring is.

Laminate flooring is a multi-layer synthetic flooring product that amalgamates a photographic applique layer with a clear protective layer.

Its popularity stems from its ability to emulate wood, stone, or even ceramic tiles while being significantly less expensive and easier to maintain.

Now, onto the advantages; laminate flooring is not only economically friendly but incredibly durable and resistant to scratches.

It’s an excellent choice for high-traffic areas and homes with pets or children. The variety of styles makes it a versatile choice for any interior design aesthetic.

But let’s circle back to the importance of a level surface. The very nature of laminate flooring, a floating floor system not directly fastened to the sub-floor, requires a flat surface.

This is to prevent “tenting” or lifting of the laminate, which can lead to premature wear and tear, not to mention the annoying creaking sound.

A few years back, eager to infuse a touch of modernity into my quaint kitchen, I decided on a beautiful rustic oak laminate flooring.

Despite a warning from a friend about the slight unevenness of my kitchen floor, I proceeded, convinced that a bit of unevenness wouldn’t hurt.

A few weeks post-installation, I started noticing gaps between the planks and an irritating creaking noise.

It was a hard lesson in the importance of a level surface for laminate flooring, which came with the added cost of re-installation. So, trust me when I say a flat surface is not an installation step you want to overlook.

Assessing the Uneven Floor

Before diving into the installation of laminate flooring, it’s essential to assess the level of your floor. Here are some methods to determine if your floor is uneven:

Methods to Determine if Your Floor is Uneven

  1. Visual inspection: One of the most basic ways to spot an uneven floor is by visual inspection. Look for gaps under baseboards and check if furniture is leaning to one side.
  2. Using a level: A more accurate method is using a level. Place it on different areas of the floor. If the bubble isn’t centered, you have an uneven floor.
  3. Placing a straightedge: For a more comprehensive inspection, place a straightedge across the length and width of the room. Any gaps between the floor and the straightedge indicate unevenness.

We noticed our dining table wobbling when we moved into our new home. At first, we thought the table was the issue until we used a level and discovered the floor was uneven!

Potential Reasons for an Uneven Floor

There could be a variety of reasons why your floor is uneven. Some of the most common are:

  1. Subfloor issues: Your subfloor might not have been installed correctly or could have been damaged.
  2. Structural problems: If your home is old, the joists and beams may have shifted over time, causing floors to dip or bulge.
  3. Settling or moisture damage: Over time, a house can settle, causing floors to become uneven. Additionally, moisture can lead to wood warping and swelling, creating an uneven surface.

Understanding the cause of your uneven floor will help you determine the best solution before installing your laminate flooring.

Preparing the Uneven Floor

1. Subfloor Preparation

Before installing your new laminate flooring, properly preparing the uneven subfloor is paramount.

Fixing low spots:

You must fill in the low spots on your floor. Make sure to use a good-quality self-leveling compound.

When I was prepping my living room floor, I had a couple of really stubborn low spots. It took a couple of applications of the compound, but the floor was perfectly flat.

Leveling high spots:

Any high spots on the floor will need to be sanded down. Be careful not to overdo it, you don’t want to create a low spot while trying to correct a high one!

Addressing structural issues:

Consulting a professional would be advisable if the unevenness is due to structural issues. They can assess the situation and make the necessary adjustments.

2. Moisture Mitigation

Next, it is imperative to protect your new floor from moisture. Install a vapor barrier, a thin plastic or foil sheet layer, to prevent moisture from seeping into your laminate flooring.

3. Proper Cleaning and Debris Removal

Finally, ensure that the subfloor is clean and clear of any debris. Sweep and vacuum thoroughly.

When I was installing my laminate, I found that taking an extra moment to ensure the floor was completely clean made a huge difference.

A clean subfloor means a smoother installation and a better end result.

Choosing the Right Underlayment

The underlayment is a crucial component of the flooring installation process, often overlooked but significantly impactful.

It’s a thin, soft layer between your subfloor and your new laminate flooring, acting as a buffer.

The underlayment can serve many purposes, like providing insulation, soundproofing, and, most importantly, helping to level out minor unevenness in your subfloor.

Types of Underlayment Available

Several kinds of underlayment are available, each boasting unique benefits. Foam underlayment is a popular choice due to its affordability and simplicity of installation.

It provides a small amount of insulation and can help alleviate minor unevenness. Another option is cork underlayment, which offers superior soundproofing and is environmentally friendly.

However, it’s important to note that it can be more costly. Lastly, felt underlayment provides excellent insulation and contains a vapor barrier, but it tends to be the most expensive.

Selecting the Appropriate Underlayment

Choosing the right underlayment for your uneven floor depends on your needs and the severity of your floor’s unevenness.

For small imperfections, a foam underlayment might be sufficient. For more significant unevenness, you may want to consider the thickness and density of cork or felt underlayment.

When faced with this decision, I was drawn to the cork underlayment. Despite its higher cost, I was sold on its soundproofing capabilities and how it would contribute to evening out my floor.

Plus, being eco-friendly was a welcome bonus! The result was astounding – my new laminate flooring looked fantastic felt comfortable, and the soundproofing made my living room the peaceful retreat I’d always wanted it to be!

Installing Laminate Flooring

Step-by-step Guide to Installing Laminate Flooring

1. Acclimating the Laminate Planks

  • Acclimating the laminate planks is a critical first step that should not be overlooked.
  • I left my laminate flooring in the room where it would be installed for about 48 hours.
  • This allowed the planks to adjust to the room’s temperature and humidity.

2. Establishing a Starting Point

  • I chose the longest, straightest wall as my starting point.
  • This ensured that the installation process went as smoothly as possible.

3. Installing Underlayment

  • I laid out my cork underlayment, ensuring it extended beyond the edges of my installation area.
  • I overlapped the seams and taped them down to create a moisture barrier.

4. Laying the Laminate Planks

  • Starting from my established point, I began installing the planks.
  • Remember always to stagger the joints for a more natural appearance.

5. Trimming and Finishing Touches

  • Once all the planks were installed, I trimmed the excess underlayment and installed quarter-round molding to cover the expansion gap.

Tips for Handling Uneven Areas During Installation

  1. Shimming: I used shims to level out the flooring when I encountered minor unevenness. This is a simple solution that can make a big difference.
  2. Using self-leveling compound: I used a self-leveling compound for larger uneven areas. Be sure to follow the manufacturer’s instructions on how to mix and apply the compound properly.
  3. Ensuring proper gaps: It’s essential to ensure proper expansion gaps around the room’s perimeter. I discovered that skipping this step can lead to warping or buckling of the laminate floor due to changes in temperature and humidity.

Installing laminate flooring may seem daunting, but with careful preparation and patience, even a novice DIYer like myself could transform a room. The satisfaction of seeing my new, even quiet floor was definitely worth the effort!

Maintaining Laminate Flooring on an Uneven Floor

Keeping your laminate flooring in optimal condition, especially when installed on uneven flooring, requires extra care and attention.

Here’s my personal experience and handy tips on how to maintain it.

Cleaning and Care Tips

Cleaning laminate flooring is a fairly simple process. However, when I first installed mine, I quickly realized it wasn’t quite the same as cleaning a regular hardwood floor.

A dry mop or vacuum works best for regular cleaning, as excess water can seep into the seams and cause damage.

I used a laminate-specific cleaner and a slightly damp mop when my floors needed a deeper clean.

Addressing Issues Like Creaking or Shifting

  • Despite best efforts, you might encounter some creaking or shifting with your laminate flooring. I certainly did.
  • At one point, a few months after installation, I noticed a particular plank had started to creak whenever I walked over it.
  • After doing some research, I found out it was due to a small gap that had formed underneath the plank.
  • I addressed this by applying some laminate floor gap filler, which solved the issue immediately.

Regular Inspections and Maintenance

It’s crucial to conduct regular inspections of your laminate flooring.

I make it a habit to inspect my floors every few months, looking out for any signs of wear, lifting, or shifting.

During one of these routine checks, I discovered some lifting on a plank near the entrance.

I was able to catch it early and prevent further damage by using a small amount of adhesive and a heavy object to press down the plank until the glue dried.

I’ve kept my uneven laminate floor in good condition by staying vigilant and addressing issues as soon as they arise.


In sum, maintaining laminate flooring requires a consistent blend of regular cleaning, addressing minor problems promptly, and performing systematic inspections.

These key points have helped me keep my uneven laminate flooring in good condition. The importance of proper preparation cannot be overstated.

A well-prepared foundation can prevent numerous issues, from creaking to shifting.

Let’s not forget that while DIY solutions can handle most minor repairs, consulting professionals becomes necessary when dealing with significant flooding issues.

They bring in-depth knowledge and experience, ensuring that repairs are carried out effectively and safely.

On the whole, laminate flooring on uneven floors is absolutely feasible. You can maintain its beauty and functionality for years with the right care and attention.

Never underestimate the potential of a bit of knowledge, a dash of DIY spirit, and the willingness to call in professionals when needed.
