Process

Remove

We gently prise out decayed and damaged timber from windows, frames and sills - retaining as much of the original wood as we can.

Replace

Where decay is severe our skilled carpenters replace sections of timber with new joinery work to closely match the original.

Fill

We treat the remaining timber with a multi-stage epoxy resin repair system called Repair Care

Smooth

Using specialist tools, our trained sash window repair specialists carefully smooth the surface of the repair to match the shape of the original timber, so that it blends seamlessly.

Finish

Finally, the window is stained or painted as required.

Maintain

We also offer a preventative maintenance service for windows to reduce or prevent future decay.

The unique benefits of Repair Care

All of our window restorers are specially trained and certified in the Repair Care system, providing assurance that each repair is conducted with expertise and sensitivity to the building’s requirements. Repair Care is a multi-stage epoxy resin system with versatile product options that cater to every repair scenario.

The resin maintains its form during application, allowing us to create external corners and three-dimensional shapes effortlessly. Once cured, Repair Care can be drilled, stained, or painted just like timber. This innovation ensures the longevity and durability of our repairs, providing an enduring solution for the preservation of London’s architectural treasures.
