How Can You Fix A Cupped Hardwood Flooring?

If you're considering installing hardwood floors in Los Angeles, it's essential to be aware of potential issues, such as floorboard cupping. Addressing these problems promptly is key to avoiding costly replacements down the line.

Dealing with a cupped floorboard early on is relatively straightforward! You can follow DIY tutorials and employ repair techniques, though consulting a professional is advisable.

In the following guide, we'll walk you through the steps to remedy cupped hardwood flooring. Let's get started!

Why Does Cupping Occur?

Cupping typically arises due to moisture-related issues. Excess moisture causes the edges of floorboards to swell, creating a dip in the center and resulting in a cupped appearance.

Here are some additional reasons for floorboard cupping:

Moisture Imbalance: Uneven moisture levels across the floorboards can lead to differential expansion, causing cupping.

Inadequate Moisture Barriers in Subflooring: If the subfloor installation is not done properly with proper sealing and moisture protection, it causes moisture from the subfloor to rise and affect the flooring. So, along with proper hardwood floor installation in Los Angeles, checking the subfloors is also crucial.

Water Damage: Leaks, spills, flooding, and prolonged exposure to high humidity levels can contribute to floorboard cupping.

How to Fix Cupped Floorboards

Now, let's explore how to effectively address cupped floorboards and restore your flooring's appearance.

Identify the Source of Moisture: 

Locate and eliminate any sources of excess moisture, such as leaks. Use a dehumidifier to reduce humidity levels in the air.

Determine the Type of Cupping: 

Assess whether the cupping is concave (high edges, dipped center) or convex (low edges, bulged center), as each requires different repair methods.

Allow the Affected Area to Dry:

Let the cupped area dry naturally for a few days. Use a moisture meter to ensure the moisture levels stabilize.

Sanding and Refinishing: 

Once dry, use a belt sander or drum sander to level the surface of the floorboards. Avoid over-sanding to prevent damage. Apply a uniform coat of finish recommended by the manufacturer.

Monitoring and Maintenance: 

Regularly monitor humidity levels and promptly clean up spills. Use a dehumidifier if needed to control indoor humidity. Proper maintenance ensures the longevity and optimal condition of your hardwood floors.

When considering hardwood floor installation in Los Angeles, familiarize yourself with the maintenance guide. Regular maintenance and timely repairs can extend the lifespan of your hardwood flooring and keep it looking its best.
