I remember when I first bought my 100-year-old cottage. I was so excited to be living in a piece of history, but I quickly realized that the charming old floors came with a few quirks. The kitchen floor sloped so much that my plates kept rolling off the counter, and the living room felt like a carnival ride. After months of tripping over the uneven surfaces, I decided enough was enough. I was ready to level the floors and reclaim a sense of stability in my home. My journey to learn how to level my wood floors taught me so much about patience, perseverance, and the importance of good tools. But most importantly, it taught me that even the most daunting DIY projects can be tackled with careful planning and a little bit of elbow grease. So, if you’ve got an uneven wood floor in your old house, don’t despair. Read on, and let’s get started!

Assessing the Problem and Deciding Your Approach

Before you start leveling, it’s important to understand the severity of the unevenness and the best approach to tackle the problem. The first step is to assess the situation. Walk around the floor, paying close attention to any areas that feel uneven or bouncy. You can use a level to confirm the degree of unevenness and identify the areas that need the most attention.

There are two main approaches to leveling a wood floor: **floor leveling compound** and **shimming.**

Floor leveling compound is a self-leveling concrete product that is poured over the existing floor. It’s often used for larger areas or when there are significant height differences. Shimming involves placing thin wooden wedges, sometimes called shims, between the floor joists and the subfloor to raise the sunken areas. This method tends to be more labor-intensive but is often preferred for smaller areas or when you want to avoid adding extra weight to the floor.

Detailed Explanation of Each Approach:

Floor Leveling Compound:

Floor leveling compound is a versatile solution that can be used to fill in gaps, level out dips, and create a smooth, even surface. It comes in different formulations, including self-leveling compounds, thin-set mortars, and patching compounds. Here’s a breakdown of the process for using floor leveling compound:

1. Prepare the Subfloor: Begin by cleaning the subfloor thoroughly and removing any debris, dirt, or loose materials. This ensures that the leveling compound adheres properly. If there are any cracks or gaps in the subfloor, you’ll need to fill them with wood filler or patching compound before applying the leveling compound.
2. Mix the Compound: Follow the manufacturer’s instructions carefully when mixing the compound. Use a drill with a mixing attachment to ensure that the compound is thoroughly blended. It’s important to mix only as much as you can use in about 30 minutes, as the compound starts to harden quickly.
3. Pour the Compound: Once mixed, pour the leveling compound onto the subfloor and spread it evenly using a trowel or squeegee. Work quickly and efficiently to ensure that the compound flows smoothly and levels itself.
4. Allow the Compound to Dry: Let the leveling compound dry completely before walking on it. Drying time can vary depending on the type of compound used, but it generally takes 24 to 48 hours.
5. Sand the Surface: Once the leveling compound is completely dry, sand the surface to smooth out any bumps or uneven areas. This will create a smooth finish for your new flooring.

Shimming:

Shimming is a more traditional method of leveling wood floors, and it’s often preferred for older houses with smaller areas of unevenness. Here’s a breakdown of the process for shimming:

1. Identify Low Spots: Carefully inspect the subfloor to identify any areas that are lower than the surrounding flooring. This can be done by using a level or by simply walking around the floor and feeling for any dips or unevenness.
2. Cut Shims to Size: Once you’ve identified the low spots, cut shims to the appropriate size. The shims should be long enough to span the width of the floor joist and thick enough to raise the subfloor to the desired height. Most shims are made of wood or plastic and can be purchased from any hardware store.
3. Secure Shims to the Joists: Place the shims between the floor joists and the subfloor, ensuring that they are properly positioned to raise the subfloor to the desired level. Use wood glue or screws to secure the shims in place.
4. Install a New Subfloor: Once the shims are in place, you can install a new subfloor over the shims to create a smooth, even surface for your new flooring. Plywood or OSB (oriented strand board) are commonly used for subflooring.

Expert Tips and Advice:

To make the process of leveling your wood floors in an old house smoother, consider these tips:

• Get Professional Help: If you’re not comfortable with DIY projects or if the unevenness of your floors is significant, consider hiring a professional contractor. They have the experience and expertise to handle complex leveling projects and ensure that the new floor is correctly installed.
• Use Quality Materials: When using leveling compound, choose a good quality product that is designed for wood floors. Check the manufacturer’s specifications to ensure that the product is suitable for your application. Similarly, when shimming, use high-quality shims that are cut to the right size and will hold up well over time.
• Protect Yourself: Always wear appropriate safety gear, including gloves, goggles, and a dust mask when working with leveling compound or shims. These materials can be dusty and can irritate your skin and eyes.
• Work in Small Areas: If you’re working with a large area, divide it into smaller sections and tackle them one at a time. This will help you to ensure that the leveling compound dries evenly and avoids cracks.
• Check for Moisture: Ensure that the subfloor is dry before applying any leveling compound. Excess moisture can interfere with the drying process and affect the adhesion of the compound.

Leveling a wood floor in an old house can be a challenging but rewarding project. By following the steps outlined above and using high-quality materials, you can transform your uneven floors into a smooth, even surface that will stand the test of time.
