DIY Guide: Simple Steps to Fix Your Uneven Floors

Fix Your Uneven Floors

An uneven floor can cause frustration and even danger in a home or workspace. From tripping hazards to foundational issues, an uneven floor is a problem that should be addressed ASAP. While it may seem daunting to fix, with the right tools and steps, you can fix your uneven floor with ease. This DIY guide will walk you through simple steps to fix your uneven floors and keep them sturdy for years to come.

Assessing the Cause of Uneven Floors

Before getting started, it’s important to determine the cause of your uneven floors. Perhaps it is a result of natural settling, or it could be more serious like a foundation problem. Understanding the cause will give you a better idea of how to tackle the issue. For example, if the cause is natural settling, the solution may be easier than dealing with a foundation issue. Here are a few things to consider when assessing the cause of uneven floors:

1. Age of the building: Older buildings may have uneven floors due to wear and natural settling.
2. Previous work done: If previous building work was done incorrectly, such as lack of support or uneven leveling, this could cause uneven floors.
3. Water damage: Moisture caused by leaks or flooding can cause wood floors to warp, creating an uneven surface.
4. Foundation issues: Uneven floors can be a sign of more significant foundation issues. These can include structural damage, shifting or settling.

If the problem is significant and beyond your expertise, it’s best to consult with a professional.

Preparing to Fix Your Uneven Floor

Once you’ve determined the cause, it’s time to prepare to fix your uneven floor. Here are some general steps to follow:

1. Clear the area: Remove any furniture or obstacles from the area.
2. Have the right tools: Depending on the method you choose, the necessary tools can vary. For example, if you’re using a self-leveling compound, you’ll need a mixer and trowel.
3. Wear protective gear: Since you’ll be working with tools and potentially chemicals, it’s important to wear protective gear. This includes gloves, goggles, and a mask.
4. Know your flooring: Before proceeding, make sure you know what type of flooring you have. Different materials require different treatments.

DIY Methods for Repairing Uneven Floors

There are several DIY methods available for fixing uneven floors. Here are a few options to consider:

Self-Leveling Compound

A self-leveling compound is an effective way to fix an uneven floor. This method can be used for both concrete and wooden floors. Here’s how to use it:

1. Prepare the surface: Make sure the floor is clean and dry before beginning.
2. Mix the compound: Follow the manufacturer’s instructions for mixing the compound.
3. Apply the compound: Pour the self-leveling compound onto the low areas of the floor and use a trowel to spread it evenly.
4. Allow the compound to dry: Give the compound time to dry completely before walking or putting any weight on it.

Patching Compound

A patching compound can also be a good option for fixing small areas of an uneven floor. You’ll need the following supplies:

1. Patching compound: Purchase a patching compound designed for your flooring material.
2. Trowel: A trowel will be needed to apply the patching compound.
3. Sandpaper: Sandpaper may be used to smooth down the surface of the compound.

Here’s how to use a patching compound:

1. Prepare the surface: Make sure the floor is clean and dry.
2. Mix the compound: Follow the manufacturer’s instructions for mixing the patching compound.
3. Apply the compound: Spread the patching compound evenly onto the low areas of the floor using a trowel.
4. Allow the compound to dry: Wait for the compound to dry completely, then sand it down to make it level with the rest of the floor.


If the issue is with wooden floors, using shims can be an effective and affordable way to fix the unevenness. You’ll need:

1. Shims: Purchase pre-cut wooden shims.
2. Handsaw: A handsaw will be needed to trim the shims to the correct size.
3. Hammer: A hammer will be needed to secure the shims into place.

Here’s how to use shims:

1. Determine the low area: Walk around the room to determine where the low areas are.
2. Trim the shims: Use a handsaw to trim the shims to the correct size. Be sure to check as you go to ensure a snug fit.
3. Hammer the shims: Using a hammer, gently tap the shims into place. Be sure to not hit the shim too hard as this can cause damage to the floor.
4. Check for level: Once you’ve placed all the shims, check for level. If the floor is still uneven, adjust the shims as needed.

Preventing Further Unevenness

Now that you’ve fixed your uneven floor, it’s important to take steps to prevent further issues. Here are a few things you can do:

1. Monitor moisture and water damage: Keep an eye on water damage and moisture to prevent warping or rotting of wooden floors.
2. Keep rooms at consistent temperatures: This helps prevent sagging or shifting.
3. Address foundation issues: If the uneven floors were due to foundation issues, get them addressed immediately to prevent further damage.
