Unnoticeable When Closed,
Unobtrusive When Open

Draughty windows are one of the most common complaints in period properties. Gaps around sash and casement frames allow cold air in and warm air out, making rooms uncomfortable and driving up heating costs.

At Timber Window Repair Services, we install high-quality draught proofing systems specifically designed for timber windows. Our seals are discreet, durable and sympathetic to the appearance of your original windows — you get all the benefits of a modern draught-free window without losing any of the character.

Draught proofing is one of the most cost-effective improvements you can make to a period property. It can be carried out as a standalone service or as part of a full window restoration.

Benefits of Draught Proofing

Reduced Heat Loss

Properly sealed windows can significantly reduce the amount of heat escaping through gaps, helping to maintain a comfortable temperature throughout your home.

Lower Energy Bills

Less heat escaping means your boiler works less hard. Draught proofing is one of the simplest and most affordable ways to improve the energy efficiency of a period property.

Reduced Noise

Sealing gaps around window frames also helps to reduce the amount of external noise entering your home — particularly beneficial for properties on busy roads.

No Replacement Needed

Draught proofing allows you to retain your original timber windows while dramatically improving their performance. There is no need to replace them with uPVC alternatives.

Discreet & Sympathetic

Our brush-pile seals are fitted into the window frame itself and are virtually invisible once installed — preserving the appearance of your period windows.

Conservation Area Approved

Draught proofing is acceptable in conservation areas and listed buildings, making it the ideal solution where window replacement is restricted, or not permitted.

How We Do It

We use brush-pile seals, fitted precisely into the rebates and channels of your sash or casement windows. For sliding sash windows, seals are installed into the meeting rail, the sash channels and the top and bottom of the frame. For casement windows, compression seals are fitted around the full perimeter of the opening sash. All work is carried out neatly and with minimal disruption, and windows are left fully operational on completion.
