Windows are a defining feature of historic buildings, contributing to their architectural character and playing a crucial role in their performance. Over time, timber frames, glazing, and ironmongery can deteriorate due to exposure to the elements, poor maintenance, or past repairs using inappropriate materials. Rather than replacing original windows, careful repairs can extend their lifespan, retain their historic integrity, and improve their efficiency.

Why Historic Window Repairs Matter

Many period properties feature timber sash windows, casement windows, and leaded lights, all of which were designed to be repairable. Unlike modern mass-produced alternatives, these traditional windows can often be restored to full working order while preserving the craftsmanship that makes them unique.

Common issues that arise with historic windows include:

  • Rot and decay in timber frames, particularly where moisture has been trapped by modern paints or sealants.
  • Draughts and rattling due to worn or missing putty, loose glazing bars, or failed joints.
  • Broken or missing ironmongery, such as catches, pulleys, and stays, affecting functionality.
  • Paint build-up and stiff operation, particularly in sash windows, where excessive layers of paint can prevent smooth movement.

The Benefits of Repairing Over Replacing

Too often, historic windows are removed and replaced with modern alternatives that fail to match the original detailing. Repairing and upgrading existing windows is not only more sustainable but also ensures that the building retains its historic character.

Key benefits of window repairs include:

  • Preserving original materials and craftsmanship that cannot be replicated with off-the-shelf replacements.
  • Enhancing energy efficiency through discreet draught-proofing, secondary glazing, or careful reglazing with appropriate glass.
  • Maintaining the building’s aesthetic integrity, ensuring the proportions and detailing remain true to the period.
  • Reducing costs and environmental impact by avoiding unnecessary replacements and landfill waste.

Our Approach to Window Restoration

At Craft Build, we specialise in restoring, repairing, and upgrading historic windows while ensuring they remain functional, durable, and sympathetic to the building’s character. Our approach includes:

  • Careful timber repairs, using traditional techniques to replace only the damaged sections rather than entire frames.
  • Reinstating proper operation, ensuring sashes run smoothly and casements open and close as intended.
  • Using breathable paints and finishes, preventing moisture from becoming trapped and causing further deterioration.
  • Improving thermal performance, where appropriate, while maintaining the appearance and functionality of the original windows.

For historic buildings, well-maintained windows are key to both aesthetics and longevity. If your property’s windows are showing signs of wear, thoughtful repairs can restore their beauty and function for years to come.
