Timber Box Frame Repair in Sunbury-On-Thames , Surrey

Preserving original joinery requires a careful, materials-led approach. We specialise in timber splicing, where we surgically remove decayed sections of your box frame and replace them with high-quality, seasoned timber. This method is particularly effective for pulley stiles and bottom rails that have suffered from water ingress over time. By rebuilding the frame rather than removing it, we keep your interior plaster and exterior brickwork undisturbed, saving you the cost and mess of wider building works.

Yes, our team frequently performs extensive rotten sill repairs. We cut away the damaged, soft wood and splice in new, durable hardwood or Accoya sections that are primed and sealed to prevent future moisture penetration. This process restores the structural integrity of the window base, allowing the sashes to sit correctly in the box frame again. This is a common requirement for period villas in the Sunbury-On-Thames area and is far more sustainable than replacing the entire unit.

For properties located within Spelthorne conservation areas, maintaining original sightlines and authentic profiles is essential. We understand the local planning landscape and ensure all our joinery work adheres to strict conservation requirements. Whether you are dealing with traditional Victorian box frames or delicate Georgian glazing, we provide high-quality repairs that satisfy local authorities while significantly improving the comfort and thermal performance of your home.

Every project begins with a detailed sash survey where we physically inspect your frames, pulleys, and sills to provide a clear, fixed written quotation. As a FENSA registered specialist, we maintain high standards across all our installations and repairs. If you are dealing with a dropped sash, a snapped cord, or accidental damage requiring immediate attention, we offer same-day emergency call-outs within our 15-mile operating radius. For urgent repairs or to book your survey, call 020 7046 0157 between 08:00 and 18:00, Monday to Saturday.
