Probably the Best Wooden Sash Window Renovation Service in London
Sash Window Draught Proofing London
Part of any good quality wooden sash window renovation service should definitely include draught proofing or insulation of some kind. The reason draught proofing is so important when carrying out sash window renovation is the fact that all your sash cords and parting beads will all need to be removed and replaced as part of the renovation work and this is the ideal time to install the draught proofing system. Once the window is fully renovated and refurbished the window can be painted further enhancing the aesthetics of your original period sash windows. Once your windows are renovated all the windows will slide up and stay up and when closed they should be draught free and secure.

As a family-run business established in 1994, we have spent over 30 years restoring traditional timber windows using expert craftsmanship and time-honoured restoration techniques. Rather than recommending unnecessary replacements, our experienced restorative joiners focus on renovating existing wooden windows to improve their appearance, performance and longevity while preserving the original character of your property. Every project is completed by our dedicated in-house team, ensuring exceptional workmanship, honest advice and a personal level of customer care from your initial quotation through to completion.
Restore the Beauty and Performance of Your Original Timber Windows
Years of exposure to the elements can leave wooden windows looking tired and performing poorly. Common issues such as peeling paint, rotten timber, sticking sashes, broken sash cords, worn pulley systems and rattling frames can all affect both the appearance and functionality of your windows.
Our wooden window renovation service is designed to breathe new life into original timber windows while preserving their historic character. Every renovation begins with a thorough assessment to determine the condition of the existing windows before carrying out the most appropriate repairs. Depending on the project, we may replace damaged timber sections, renew sash cords, repair glazing bars, service pulley wheels, rebalance sash windows, replace locks and catches, repair window frames and carry out complete refurbishment where required.
As part of the renovation process, we also install discreet draught-proofing systems that significantly reduce heat loss and eliminate unwanted rattles, helping to improve comfort and energy efficiency without altering the traditional appearance of your windows. The result is beautifully restored timber windows that operate smoothly and continue to protect your property for many years to come.
Expert Renovation for Period and Heritage Properties
Period properties deserve specialist care, and our renovation work is always carried out with respect for the original design and craftsmanship of the building. Whether your home is Victorian, Georgian, Edwardian, located within a conservation area or formally listed, our experienced team understands the importance of maintaining its architectural integrity.
Where original components are beyond repair, we manufacture bespoke hardwood replacement sections in our independent workshop to replicate the existing mouldings, glazing bars and timber profiles as closely as possible. This enables us to preserve the property’s original appearance while strengthening its long-term durability.
For homeowners looking to improve thermal performance, wooden window renovation can also be combined with sash window draught proofing or slimline double glazing where suitable and permitted. Our objective is always to retain as much of the original timber as possible while delivering a high-quality renovation that enhances both the appearance and functionality of your windows.

Frequently Asked Questions
What does a sash window renovation involve?
A Mortice & Green sash window renovation is a comprehensive restoration of an original sash window to full working order and improved condition. It typically includes: removing the sashes and stripping all existing paint back to bare timber; repairing or replacing any rotted or damaged sections of timber; re-glazing where required; fitting new sash cords; installing draught proofing brush seals; repainting or priming all surfaces; and re-hanging both sashes to operate smoothly and correctly. The result is a window that looks and performs as it should have done when first installed.
Is it better to renovate or replace original sash windows?
In most cases - particularly for Victorian and Edwardian period properties in London - renovation of the original windows is preferable to replacement. Original sash windows were made from old-growth timber that is denser and more durable than modern equivalents. A well-executed renovation restores both function and appearance, retains the original character of the property, and at the same cost of replacement typically produces a longer-lasting result. Mortice & Green always provides an honest assessment of whether renovation or replacement is the right choice for your specific windows.
How long does a sash window renovation take?
A full renovation of a single sash window - including stripping, repairs, draught proofing, and re-hanging - typically takes one to two days depending on the extent of the timber repairs required. For properties with multiple windows requiring renovation, we can work on a programme that suits your schedule. We always give you a clear programme at the quotation stage.
How much does sash window renovation cost in London?
A full sash window renovation typically costs from £400 to £900 per window depending on the size of the window, the extent of the timber repairs required, and whether the client requires painting or just priming. Properties with many windows may be quoted at a combined rate. Mortice & Green provides free, no-obligation quotations - call 020 7118 9191 to arrange a survey.
Can you renovate sash windows in a conservation area or listed building in London?
Yes. Sash window renovation - restoring the existing windows to working order without changing their external appearance - is generally acceptable in all conservation areas and on listed buildings. It is often the only option available to owners of listed buildings where replacement windows would not be approved. Mortice & Green has extensive experience working on period properties across London's conservation areas and can advise on any specific requirements at the survey stage.
What is the difference between sash window renovation and sash window refurbishment?
Renovation typically refers to a comprehensive restoration of the window to its original condition - including structural timber repairs, re-glazing, new sash cords, and draught proofing. Refurbishment can refer to a lighter scope of work focused on improving the functional and cosmetic condition of the window without necessarily addressing all underlying structural issues. Mortice & Green will assess your windows and recommend the most appropriate scope of work based on their actual condition.
