Sash Windows in London
Repair a Sash is a London specialist in timber sash windows, working with homeowners across the capital’s period and character homes. Whether your sash windows need attention now or you are simply exploring what is involved, our focus is on giving honest, practical advice based on the condition of the windows in front of us.
Sash windows can need very different things depending on their age and condition. Some homeowners come to us for straightforward repairs, others want draught proofing to improve everyday comfort, and some are looking at new sash windows or a double glazing upgrade. Wherever you are starting from, we can help you understand the right next step.
Timber sash windows for London homes
Timber remains the material of choice for sash windows in London’s Georgian, Victorian, and Edwardian properties, and for good reason. It suits the proportions and character of period architecture in a way that alternative materials cannot replicate, and it can be repaired, renovated, and refinished over many decades rather than discarded and replaced.
For homeowners with original timber sash windows, or wooden sash windows fitted as later replacements, the right approach depends entirely on the condition of what is already there. A window that is fundamentally sound may need nothing more than draught proofing. Where deterioration is more advanced, new sash windows may be the more sensible long-term route. We assess each property individually rather than applying a single standard recommendation, because period properties across London vary considerably in how their original windows have aged and been maintained.
Our sash window services
We offer a focused range of sash window services, each suited to a different starting point.
New sash windows
Where existing sash windows are too deteriorated to repair or renovate cost-effectively, we manufacture and install new sash windows designed to match the character and proportions of the property.
Sash window repair
For windows with specific issues such as rotten timber, broken cords, or damaged frames, our sash window repair service addresses the problem directly, restoring function and appearance without unnecessary replacement.
Draught proofing and renovation
Where existing windows are basically sound but draughty, rattling, or sticking, our draught proofing and renovation service improves comfort and everyday operation while keeping the original windows in place.
Double glazing for sash windows
For homeowners who want a meaningful improvement in thermal and acoustic performance while retaining the original box frame, our new double glazed sashes service fits new double glazed sashes within the retained original box frame.
Designed for period properties across London
A large proportion of our work is in London’s period housing stock, where sash windows are often original features that contribute directly to the character of the building. Working on these windows requires an appropriate approach: understanding the original proportions, respecting existing detailing, and recognising that what suits one property may not suit another.
For homes in conservation areas or listed buildings, the approach to sash windows often needs particular care, and requirements can vary depending on the property and the local authority. We are experienced in working within these contexts and will always give you a clear, honest view of what is likely to be appropriate for your specific situation.
Why homeowners choose Repair A Sash
We work specifically with London homeowners, and a significant proportion of our projects involve period properties where the details genuinely matter. Our approach is built on careful assessment rather than a standard sales pitch: we look at the actual condition of your windows and recommend the service that suits them, not the one that suits us.
This means we will recommend repair or draught proofing where that is the more sensible and cost-effective route, and we will be equally clear when full replacement or a double glazing upgrade is the better long-term answer. Our work is carried out with care and attention to detail, and is fully guaranteed.
