Gap Filling with Timber Strips for Wood Floors in Kent

When gaps between floorboards are too wide for resin filling, timber strip gap filling is the ideal solution. Natural Finishers provides expert strip gap filling services in Maidstone, Kent, and across the South East. We use carefully selected and shaped timber strips to close large gaps, creating a solid, beautiful, and draught-free floor.

Timber strip filling involves cutting thin slivers of matching wood to fit precisely into the gaps between your floorboards. Once glued in place and sanded flush, the strips become virtually invisible, blending seamlessly with your existing floor. This method is perfect for older properties and period homes where boards have shrunk over decades, leaving substantial gaps.

How Timber Strip Gap Filling Works

  1. Assessment – We measure the gaps and determine the best timber match
  2. Strip preparation – Thin slivers of matching wood are carefully cut to size
  3. Gluing – Each strip is coated with wood adhesive and tapped into the gap
  4. Trimming – Excess strip material is planed or trimmed flush with the floor surface
  5. Sanding – The entire floor is sanded to create a perfectly smooth, level surface
  6. Finishing – Oil, lacquer, or wax is applied to protect and unify the floor

Benefits of Timber Strip Gap Filling

  • Ideal for gaps wider than 5mm where resin alone would crack
  • Uses real wood for a natural, authentic look
  • Timber-matched to your existing floorboards
  • Eliminates draughts and improves insulation
  • Prevents debris, insects, and dust collecting in gaps
  • Strong and permanent – strips become part of the floor

Strip Filling vs Resin Filling

For narrow gaps (under 5mm), resin filling is usually sufficient. For wider gaps, timber strips provide a more durable and stable solution. In many restoration projects, we use a combination of both methods – strips for the largest gaps and resin for smaller ones – to achieve the best possible result.

Frequently Asked Questions

What size gaps are suitable for strip filling?

Strip filling is typically recommended for gaps of 5mm or wider. Narrower gaps are usually better suited to resin filling. We assess your floor and advise the best approach.

We use timber that matches your existing floorboards as closely as possible in species, colour, and grain. Once sanded and finished, the strips are virtually invisible.

Strip filling is mainly used for plank and board floors. For parquet, resin filling is generally more appropriate due to the smaller gap sizes. We recommend the best method for your specific floor.

Yes. The strips are glued with strong wood adhesive and, once sanded flush, they become an integral part of the floor. They are designed to last the lifetime of the floor.

Absolutely. Many of our projects use both methods – timber strips for the wider gaps and resin for the smaller ones. This combination delivers the best overall result.
