Where Traditional Craftsmanship Meets Modern Performance

Our refurbishment service is designed to enhance comfort, efficiency, and longevity, while preserving the character of your original windows. Through a considered approach to conservation and sustainability, we deliver lasting improvements without compromising heritage.

  • We offer a full refurbishment service in which the sashes are carefully removed and taken to our workshop for a complete overhaul. This includes repairing or replacing rotten timber and putty, reglazing where applicable, installing a new draught-proofing system with QLon seals, and fully repainting the sashes.

  • The exact process can vary depending on the level of refurbishment required for each window.

    In most cases, the windows are carefully removed and the openings are temporarily boarded using OSB to maintain security and weather protection.

    The sashes are then taken to our workshop, where the refurbishment is carried out under controlled conditions. This may include repairing or replacing damaged timber and putty, reglazing where necessary, installing a new draught-proofing system, and fully preparing and repainting the sashes.

    Once complete, the windows are returned to site and professionally reinstalled, ensuring a high-quality finish and smooth operation.

  • This process significantly improves the performance, appearance, and operation of your windows, helping to enhance both comfort and energy efficiency.

  • A full refurbishment can typically extend the life of your windows by 10–20 years, provided they are properly maintained.

  • All refurbishment work is covered by our 5-year guarantee.

What to Expect From Your Window Refurbishment

Inside a Preservation Window Refurbishment

  • Draught-Proofing

    The benefits of draught proofing include improved insulation, removing rattles and rolls and sound proofing. Modern innovations and products allow Preservation Windows to seal any gaps around your windows and eliminate draughts without altering the appearance of your windows.

  • Repair & Repaint

    Putty repairs, repainting, and any necessary timber repairs are carried out as part of the process. The window cases are also refurbished, with mastic replaced on site where required, before a final finish is applied.

  • Slimline Vacuum Glazing (Optional Upgrade)

    Slimline vacuum glazing can be incorporated into selected refurbishment projects as a high-performance upgrade.

    This option significantly improves thermal efficiency while maintaining a traditional appearance, and is available where suitable for the existing windows.

  • Ironmongery

    When refurbishing your windows, you have the option to either replace the ironmongery with new, high-quality fittings or retain and refurbish your existing hardware. This ensures your windows look authentic while remaining fully functional, giving you the flexibility to preserve original features or update for improved performance and style.

  • Planning & Approval

    For listed buildings and properties within conservation areas, Preservation Windows provides expert guidance on all aspects of window refurbishment and replacement. We can manage the planning process on your behalf, securing the necessary approvals while ensuring your project meets heritage requirements smoothly and efficiently.
