How to Fix Gaps in Solid Wood Flooring

Solid wood flooring is a classic and durable choice for homes, offering a timeless aesthetic and long-lasting performance. However, over time, gaps can develop between the planks. These gaps are a common issue caused by seasonal changes, improper installation, or natural wear and tear. At The British Wood Flooring Company, we understand how frustrating these gaps can be, so we’ve compiled this comprehensive guide to help you address the problem effectively.

Why Do Gaps Appear in Solid Wood Flooring?

Understanding the root cause of gaps in your flooring can help you choose the best repair method:

1. Seasonal Changes: Wood is a natural material that expands and contracts with changes in humidity and temperature. In the winter, lower humidity levels can cause the wood to shrink, resulting in gaps.
2. Improper Installation: If the flooring was not adequately acclimated to the room’s environment before installation, it may shrink or expand excessively, leading to gaps.
3. Wear and Tear: Over time, heavy foot traffic and general use can cause planks to shift or wear down, creating spaces between them.
4. Age of the Flooring: Older flooring may develop gaps due to the material’s natural settlement over decades.

Tools and Materials Needed

Before you begin any repairs, gather the following tools and materials:

• Wood filler or putty (colour-matched to your flooring)
• Putty knife
• Wood glue
• Shims
• Sandpaper
• Sawdust (for DIY filler)
• Floorboards (if replacement is necessary)
• Mallet
• Clamps

Methods to Fix Gaps in Solid Wood Flooring

1. Use Wood Filler

Wood filler is a quick and easy solution for small gaps:

1. Clean the Area: Remove debris or dust from the gap using a vacuum or soft brush.
2. Apply the Filler: Use a putty knife to spread the wood filler evenly into the gap.
3. Smooth the Surface: Wipe away excess filler with a damp cloth and let it dry as per the manufacturer’s instructions.
4. Sand and Finish: Lightly sand the area for a seamless finish once dry.

This method works best for minor gaps less than 3mm wide.

2. Insert Wood Slivers

For more significant gaps, inserting wood slivers is a durable and visually appealing solution:

1. Measure the Gap: Use a tape measure to determine the width of the gap.
2. Cut the Sliver: Cut a thin piece of wood (preferably the same species as your flooring) to match the gap’s size.
3. Apply Wood Glue: Spread wood glue along the edges of the sliver.
4. Insert the Sliver: Gently tap it into the gap using a mallet.
5. Sand and Finish: Once the glue is dry, apply a matching finish to the area.

3. Refit Loose Boards

If loose boards cause the gaps, refitting them can solve the problem:

1. Identify Loose Boards: Look for planks that move when stepped on.
2. Apply Wood Glue: Lift the loose plank slightly and apply wood glue underneath.
3. Secure the Board: Use clamps to hold the plank in place until the glue dries.
4. Inspect Surrounding Areas: Check for additional loose boards and repeat the process if necessary.

4. Replace Damaged Boards

If a plank is severely damaged or warped, replacement may be the best option:

1. Remove the Damaged Plank: Carefully pry it up using a chisel or pry bar.
2. Cut a Replacement Plank: Measure and cut a new plank to fit the space.
3. Acclimate the New Plank: Allow the replacement wood to acclimate to the room’s environment for at least 48 hours.
4. Install the Plank: Secure the new board with wood glue and a mallet.
5. Sand and Finish: Smooth out the area and apply a matching finish.

5. Create a DIY Wood Filler

For a cost-effective and custom solution, make your wood filler using sawdust and wood glue:

1. Collect Sawdust: Use sawdust from the same wood species as your flooring for a perfect colour match.
2. Mix with Glue: Combine the sawdust with wood glue to form a paste.
3. Fill the Gaps: Apply the mixture to the gaps using a putty knife.
4. Smooth and Sand: Once dry, sand the area and apply a finish.

Preventing Future Gaps

To minimise the risk of gaps forming in the future, consider these preventative measures:

1. Acclimate the Wood: Allow your flooring to adjust to the room’s temperature and humidity for at least a week before installation.
2. Maintain Consistent Humidity: Use a humidifier or dehumidifier to keep indoor humidity levels between 40-60%.
3. Regular Maintenance: Clean your flooring regularly and address minor issues promptly to prevent them from worsening.
4. Professional Installation: Hire experienced professionals to ensure proper installation and minimise the likelihood of gaps.

FAQs

1. Can gaps in wood flooring close on their own? Gaps caused by seasonal changes may close when humidity levels rise, but permanent gaps require repair to prevent further issues.

2. What is the best way to prevent gaps in solid wood flooring? The keys are maintaining consistent indoor humidity levels and ensuring proper installation.

3. Can I use caulk to fill gaps in wood flooring? While caulk can be used for temporary fixes, it is not recommended for long-term solutions as it lacks the durability and finish of wood filler or slivers.

4. How often should I inspect my wood flooring for gaps? Inspect your flooring annually or whenever you notice changes in its appearance or performance.

5. Should I repair gaps myself or hire a professional? Small gaps can often be repaired with DIY methods, but professionals best handle larger or more complex issues to ensure a flawless result.
