Wood Floor Gap Filling

Gap filling of hardwood floors

Wood floor gap filling is a common procedure that addresses the natural contraction and expansion of wood floors over time. Different methods are available for filling gaps in timber floors.

Wood Floor Gap Filling - Stability and Durability

Wood floor gap filling is a popular service suitable for all real wood floors. Over time, moisture, humidity, and temperature fluctuations cause floorboards to contract and expand, resulting in gaps of various sizes.

Neglected gaps can impact the structural stability of the floor and affect its appearance and insulation. Our professional gap filling service in London provides high-quality, efficient, and time-saving solutions. We take pride in achieving outstanding results, delivering smooth and even surfaces, improved stability, and solidness.

Enhanced Insulation for Your Wooden Floor

Our professional gap filling service not only fixes gaps but also improves the insulation properties of your wood floor. Gaps compromise insulation, leading to heat loss and increased heating costs. By sealing the gaps, you can enjoy cost-effective heating, cosy warmth, and reduced draughts.

We use high-quality products that ensure long-lasting and hard-wearing results, withstanding high traffic and everyday use. Choose our professional wood floor gap filling service in London to invest in the lasting power and comfort of your floor.

Expansion Gap Considerations

While not all wood floor gaps need to be filled, expansion gaps play a crucial role in wood floor installation. These gaps allow floors to expand and contract with temperature and humidity changes. Professional installers create sufficient expansion gaps, typically ranging from ¼ to ½ inch, to ensure the floor's condition and aesthetics are preserved over time.

Resin Mixed with Saw Dust

A widely used method for gap filling wooden floors is mixing clear resin filler with sawdust collected during the floor sanding process, to create a thick putty with the same colour as the floors, applied with a spatula between the floorboards. This method is ideal for gaps on parquet floors and floorboards where the gap is less than 5 mm wide.

The advantage of this wood floor gap filling method is that it provides a basis for a smooth floor finish, dries quickly and the gap filling mixture has identical colour to your flooring because the sawdust has been collected from the sanding of your floors.

A perfect solution for floorboards gap filling in actionThe downside of resin gap filling is that it is not suitable for solid and stable planks over solid base/joist support. On non-grooved floors such as the original pine floorboards, is difficult to guarantee its durability as any movement caused by weak, cracked or over-sanded boards as well as movement in the joists will cause displacement of the filling. That is why this method is often more efficient when applied to parquet flooring or lock joint floorboards where the gap filling putty will not fall through.

To minimise the risk of gap filling putty falling through, we use exceptionally high-quality resin filler products and our wood floor gap filling service comes with inspection and refitting of the flooring, prior to the restoration.

Wood Strips Filling (Slivers) - Durable and Natural Solution

Another effective method for gap filling is using wood strips, especially for floorboards. This involves cutting strips of wood and gluing them into the gaps. Wood strips provide durability and a natural visual effect. They sit on the joists, preventing them from falling through.

The advantage of filling the gaps with wood strips is not only the durability but also the visual effect which is natural and nice. All gap filling methods are applied before the floor sanding process, ensuring a smooth surface ready for varnishing or oiling.
