Sash Window Restoration
For Over 20 Years We Have Been Restoring & Draught Proofing Sash Windows.
Sash Window Draught Seal & Overhaul Will improve energy efficiency and Ease Sliding Operation
Sash Window Draught Sealing should be considered an essential upgrade for all existing sliding sash windows.
- Sash seals stop rattles & draughts as well as reducing noise & dust.
- Sash window overhaul replaces cords & restores proper functionality.
Our sash window draught proofing & restoration service is designed to fix the most common problems associated with traditional timber sash windows.
Window brush seals are fitted as part of our sash window restoration service that includes an overhaul of the whole box sash frame to bring new life to your old windows.
Draught proofed sash windows have improved functionality and energy efficiency at a fraction of the cost of replacement period windows.
“Draught-proofing is one of the most cost effective and least intrusive ways of improving the comfort of occupants and reducing energy used for heating with little or no change to a building’s appearance.” Historic England

Sash Window Restoration Service: In More Detail
Installing effective draught seals at the same time as overhauling your existing sash windows is the best value for money service we can offer. For many home owners our Draught Seal & Restore service provides a significant, rewarding home improvement without the added expense of replacing glass. A wide range of timber window repairs can also be undertaken in conjunction with this service.
All of our more advanced window solutions include this service as the foundation.
Less than a quarter of the heat lost through a typical traditional window escapes by conduction through the glass. The rest is air leakage as draughts.
Improving Energy Efficiency
Sealing draughts in your home will return significant savings on heating and cooling costs.
Traditional double-hung sash windows are not regarded as being very energy efficient. The sliding sash window frames have inherent gaps that allow the sashes to slide and the timber frames can also warp over time, creating even larger gaps where air leakage and air infiltration will occur.
Draught-stripping your existing period sash windows can reduce the draughts by almost 90%, therefore significantly reducing the cooling or heating requirement needed for the room. Draughts make air cooling and heating systems work harder and make occupants feel uncomfortable, often adjusting room thermostats to compensate.
Whilst heat does pass through the glass itself, less than a quarter of the heat transfer through a typical sash window is by conduction, the rest is by air infiltration – draughts. Heavy curtains or close-fitting roller blinds can help cut the amount of heat transfer through glass by more than 30%.
Unaltered Heritage Appearance
We understand the charm of traditional wooden windows. All of our work is designed to be as authentic as possible.
Our draught seals are machined into the timber components to become an integral, practically invisible part of the window. Draught Seal & Restore Service is ideal for conservation areas and listed buildings.
“one of the best and least intrusive ways of achieving improved performance from windows in old buildings. This will considerably reduce heating bills and energy use… reduce noise and dust ingress… Most importantly, draught proofing does not damage the visual aesthetics of an old building.”

WEATHER PILE With Fin (Brush Seal) & UPVC Carrier
At Sash Window Specialist we have been installing the same brush system for over 20 years. It is an excellent system and simply the best choice when restoring of old windows. Our seals are of the highest quality and Made In England.
- Weather pile is recommended for use in UK Grade I and II listed buildings
- Low friction allows the sash to glide
- Brush draught seals are the best option for long life in a sliding sash window.
Air penetration resistance & water tightness test to BS 6375 & BS 5368
Schlegel Q-Lon Weatherseals are available on request. In our experience these are best used in casement windows or when acoustic sealing is the primary concern, over durability.
Range of Security & Window Furniture
Various catches effectively bring the sashes into a locked position, however, the screws holding these in place are small and these catches should not be considered an effective security measure.
