Looking after sash windows

Sash Windows UK carry out draught proofing, sash window repair, full sash window restoration and double glazed sash windows with a five year guarantee on all work.

Sash windows are an important part of most traditional Victorian properties in and around UK.  Sash Windows UK believe firmly in the restoration and maintenance of your original sash windows over, in most cases unnecessary replacement. A large proportion of sash windows in UK will have been in place for over a hundred years and if looked after and maintained well, can offer the same duration of service and more again.  We can help with draught proofing, noise reduction, heat retention, and general renovation including full redecoration if required.


Most of our work involves full sash window renovation and refurbishment. With full restoration in mind we will offer a comprehensive overhaul and Sash window draught proofing service to almost all customers. We will always repair a sash window if it is economically viable.

As beautiful and functionally good as your windows can be they do suffer from the same inherent problems. You may want to look at servicing them if they are:

Draughty through sides and meeting rail – we can eliminate this problem with our  comprehensive draught proofing system

Rattling in the wind and when vehicles pass – this will also be resolved with our draught proofing system. The draught deals serve to ‘cushion the sashes within the frame’.

Allowing dust ingress with the draughts – a weathering within the brush pile will catch all dirt and avoid the need for time consuming removal of nets and curtain for cleaning purposes.

Generally not operating well – on removal of your windows for draught proofing we will machine sashes to fit your frame better, given they most likely a hundred years old some settling and movement is normal and can be expected.

Suffering from rot and timber decay – we can splice and replace any defective timber within your window negating the need for entire replacement!

Not As Secure as you might like – security restrictions and other locking devices can be discussed and fitted as necessary.

Windows are too noisy – we can draught proof and double glaze your existing sashes in most circumstances.

London is one of our busiest areas for sash window repairs. We always try to repair sash windows rather than replace there are three simple reasons for this, it’s cheaper for you, cheaper for us and its just as effective as replacements. With over 30 years of experience repairing sash windows we pretty much know everything there is to know. That’s not to say we don’t learn new things, we’re always looking for ways to improve the service we provide our customers in London.


Sash windows were designed to be repaired. That’s why where possible you should always try to get your windows repaired. We break down a sash window repair into several different jobs, they can change depending on the state of the window. Firstly we will take your sashes out to machine them in our vans, at this stage we will also repair any problems with your sashes like rot. Once we have made any repairs required, we then machine your sashes so we are able to install U-Section and Brush Pile as part of our draught proofing system. While this is being done someone will also be repairing any problems on your box like broken pulleys, often pulleys are painted shut and are easy to fix. Once we have carried out any repairs required we will begin to put your windows back together and install our draught proofing system to stop rattling, water ingress and help reduce noise pollution.

If you think your sash windows need repairing or want to find out more about sash window repairs in London then feel free to phone us on our number or send us an email.

We have been installing sash window draught proofing in London for many years. We have one of the most dedicated teams and service thousands of sash windows each year. We carry out sash window draught proofing on nearly all of the sash windows we service be it repair, overhaul or replacement. Installing a draught proofing system costs very little and it doesn’t take a lot of time but the benefits are massive. If your windows are at all draughty, noisy or allow water/debris ingress then a draught proofing system can eliminate all of those problems.


The way draught proofing works is quite simple. while the sash window is in our van we will machine a groove that allows us to fit U-Section and brush pile to the bottom and top rail of the top sash. We then fit U-Section and Brush Pile into Parting and staffing bead. With Brush Pile fitted to these parts of the sash window it creates a watertight seal which will block any draughts or rain. With no gaps in your windows any noise will be drastically cut but if noise is an issue with your property in London we would recommend having double glazing installed to form an even better defence against noise pollution.

If you would like to know more about our draught proofing system or would like to request a free no obligation quotation for your property in London then simply email or call us on our number.
