Laminate Floor Uneven Floorboards: How to Fix Them

Laminate flooring is a popular choice for homeowners because of its durability, affordability, and easy installation. However, it requires a flat and level surface for proper installation. Uneven floorboards can cause problems when installing laminate floors, leading to a poor finish and potential damage to the flooring. In this article, we’ll discuss how to fix uneven floorboards to ensure a smooth and successful laminate floor installation.

Uneven floorboards are a common issue in older homes or those that have suffered from structural damage. It can also occur if the subfloor is not properly prepared. When installing laminate flooring over uneven floorboards, it can cause the planks to warp, buckle or crack. Not only does it look unsightly, but it can also be a tripping hazard. Therefore, it’s crucial to ensure that the surface is flat and level before installing laminate flooring.

Identifying Uneven Floorboards

The first step in fixing uneven floorboards is to identify the problem areas. You can do this by laying a straight edge or level across the floorboards and checking for any gaps or dips. If the floorboards are uneven, you’ll notice that the straight edge or level will not sit flush against the surface.

Fixing Uneven Floorboards

There are different ways to fix uneven floorboards, depending on the severity of the problem. Here are some methods you can use:

1. Sanding

If the floorboards are only slightly uneven, you can sand them down to create a level surface. Use a floor sander to remove any high spots and create a smooth surface. Make sure to wear a mask and eye protection when sanding to avoid inhaling dust or debris.

2. Shimming

If the floorboards have significant dips or gaps, shimming is a good option. Shims are thin pieces of wood that you can place underneath the floorboards to level them out. You can use a combination of shims and sanding to create a level surface.

3. Self-leveling Compound

If the floorboards are severely uneven, you can use a self-leveling compound to create a smooth surface. Self-leveling compound is a cement-based product that you can pour over the floorboards to fill in any dips or gaps. It’s easy to use and dries quickly, creating a smooth and level surface for laminate flooring installation.

Preparing the Subfloor

Once you’ve fixed the uneven floorboards, it’s essential to prepare the subfloor properly before installing laminate flooring. Here are some steps you can take:

1. Clean the Subfloor

Make sure the subfloor is clean and free of any debris or dust. Use a broom or vacuum to remove any dirt or debris that may be on the surface. A clean subfloor will ensure that the laminate flooring adheres properly and looks great.

2. Install an Underlayment

An underlayment is a thin layer of material that you place between the subfloor and laminate flooring. It helps to absorb sound, provide insulation, and create a smooth surface for the laminate flooring. You can choose from different types of underlayment, such as foam, cork, or felt.

3. Use a Moisture Barrier

A moisture barrier is a plastic sheet that you place over the subfloor to prevent moisture from seeping through and damaging the laminate flooring. It’s especially important if you’re installing laminate flooring in a basement or a high-moisture area.

Conclusion

Laminate flooring is an excellent choice for homeowners who want a durable and affordable flooring option. However, it requires a flat and level surface for proper installation. Uneven floorboards can cause problems when installing laminate floors, leading to a poor finish and potential damage to the flooring. By identifying and fixing uneven floorboards and properly preparing the subfloor, you can ensure a smooth and successful laminate floor installation.
