How to Fix Gaps Under Skirting Boards?

Identify the Gaps

The first step in fixing gaps under skirting boards is identifying where the gaps are. Look for gaps that are large enough to see or feel air coming through. Often, these gaps are more prominent in older homes or in areas with fluctuating temperatures.

Gather Your Tools and Materials

Before you start, gather the necessary tools and materials:

• Caulk or wood filler
• Caulking gun
• Putty knife
• Sandpaper (fine grit)
• Paint (if needed)
• Cloth for cleaning

Clean the Area

Ensure the area under the skirting boards is clean before applying any filler. Use a cloth to wipe away dust, dirt, and debris. This will allow the caulk or filler to adhere properly, creating a better seal.

Choose Your Filler

If the gaps are small, caulk is usually the best choice. For larger gaps, wood filler may be more appropriate. Choose a product that matches the material of your skirting boards, ensuring a seamless finish.

Apply the Filler

Using a caulking gun, apply the caulk along the gap in a steady motion. If using wood filler, scoop it out with a putty knife and press it into the gap, smoothing it out to even it with the surrounding surface. Be generous but avoid excess overflow.

Smooth the Surface

Once you've applied the filler, use your finger or a putty knife to smooth the surface. If you're using caulk, you can lightly wet your finger and run it along the bead to create a clean finish. For wood filler, ensure it's level with the skirting board.

Allow to Dry

Follow the manufacturer's instructions for drying times. It’s crucial to allow the filler to fully dry before proceeding to the next step to ensure a durable seal.

Sand the Area (if necessary)

Once the filler is dry, sand the area lightly with fine-grit sandpaper to create a smooth surface. This will help the skirting boards blend in seamlessly with the wall.

Paint (if needed)

If you used wood filler, you might need to paint over the area to match the skirting boards. Choose a paint that matches the existing finish for a uniform appearance.

Final Inspection

Once everything is dry and painted, conduct a final inspection. Look for any remaining gaps or imperfections, and repeat the process as necessary. Your skirting boards should now look neat and secure.
