Georgian style sash windows price guide
Georgian-style sash windows typically require more labour and skill to repair and substantially more time to reglaze than other window types like Victorian-style sash windows or casement windows with simple glazing configurations.
That’s why we have a separate price for this style of window, ensuring that you can get an accurate budgeting estimate for your project.

After rot repairs, to avoid cracks at the joints and improve the durability of our refurbishment, we also laminate the entire length of the frame with a rot-proof 4mm sheet of wood veneer. These are custom-made to fit the existing frame perfectly, so you won’t notice them—just like the logic behind tooth ceramic veneers.
8 Years guarantee on paintwork
20-year guarantee on parts repaired with Accoya or Tricoya – based on the logic that these materials are guaranteed by the manufacturer not to rot for 50 years.
