Conducting restorations
from the inside out
Whilst still full of charm, many older sash windows will fall victim to general wear and tear, weather exposure and the natural ageing of the materials they're made with. If rotten wood, pulley and cord issues or peeling and flaking of the paint are making your windows creaky and difficult to operate, it might be time to give them some TLC.
Dedicating decades to London's heritage properties, Sash Window Repairs are committed to preserving the history of your windows while ensuring they meet modern efficiency and durability standards. And it all begins with a detailed assessment. Simply call us to book your inspection and we'll identify any areas of concern. We believe that a window replacement should be the last resort, and will always look to restore and repair before we recommend a new installation.

Our meticulous window restoration process
A sash window replacement should be a last resort; it should only be carried out when the condition of the window has deteriorated beyond repair. After 4–5 years your sash windows can often start to look faded or the paint will have begun to flake or peel. This can lead to an unattractive appearance and to paint getting stuck in the sash runners, making your window creaky and difficult to open and close. With Sash Window Repairs' restoration service your windows will be restored to their former glory.

01
Thorough Assessment and Consultation
Our restoration process commences with a detailed assessment of your sash and casement windows. During the consultation, we discuss your preferences, style, and any specific requirements. This initial step allows us to tailor the restoration to your unique vision.
02
Pulley Wheel and Sash Cord Replacement
​​
We prioritise functionality by replacing worn-out or damaged pulley wheels and upgrading to high-quality UK sash cord. This ensures smooth operation and longevity for your restored windows.
03
Beading Installation for a Seamless Finish
Precision is key. We install new beading, carefully selecting materials to complement the aesthetic of your windows. This not only enhances the visual appeal but also contributes to the overall integrity of the restoration.

Old Paint Removal and Intensive Stripping
To reveal the true beauty beneath the layers of old paint, we meticulously remove the existing coatings. Our intensive stripping process is thorough, aiming to uncover the original features of your windows.
05
Sanding and Filling for Flawless Surfaces
Achieving a smooth and flawless finish is our priority. We employ professional sanding techniques to refine surfaces, preparing them for the next steps. Any imperfections are expertly filled, ensuring a pristine foundation for the final restoration.
06
Top-Quality Paint Application
​
With surfaces prepared, we apply top-quality paint or stain, paying attention to your colour preferences and maintaining the authenticity of your windows. Our skilled craftsmen ensure an even and durable finish that stands the test of time.
07
Stringent Quality Checks and Guarantees
Before completion, our team conducts stringent quality checks to ensure that every aspect of the restoration meets our high standards. We stand behind our workmanship with comprehensive guarantees, providing you with peace of mind and assurance in the longevity of your restored sash and casement windows.

Traditional sash windows that meet modern demands
Whilst the traditional sash is hard to beat in terms of style, the original wooden frames and glazing used within these units often leave a lot to be desired when it comes to thermal and acoustic performance. As part of the restoration process, we'll utilise new components and features for added security, efficiency and safeguarding.
Preserving craftsmanship and character with guaranteed results
Throughout each project, our goal is to retain the craftsmanship and skill that went into your original sash window installation. By focusing on showcasing the unique character or your property's features, we guarantee results that impress, with the added assurance that all labour and parts are fully guaranteed - and, by tackling each job from the inside out, scaffolding erection will not be required.

Archie arrived on time, re-hung a large Georgian window and did a basic refurb. The job ended up being more complicated than anticipated, and however he charged what he had quoted. Nice bloke, good punctual service - I have asked him to quote to replace / refurbish the windows in the whole property. Highly recommend
