We specialise in the draught proofing,
servicing and repair of period sash windows.

Draught-proofing is one of the most cost effective and least intrusive ways of improving the comfort for you and your family and reducing energy used for heating with virtually no change to a window’s appearance. According to the Energy Saving Trust, draught proofing your windows is one of the best ways to save money on your heating bills.

With the Addition of Our Brush Pile Draught Proofing System Less Heat Escapes and Little to No Cold Air Comes In.

We eliminate 90% of window draughts, stop the window from rattling, as well as preventing unwanted jams and helping your beautiful sash window slide smoothly. Road noise and dust ingress is also vastly reduced. We believe that older properties need to breathe so a very small amount - around 10% - of ventilation will still trickle in and out of your rooms.

We also carry out repair work to sash windows, such as sill replacements, timber repairs and glazing.

How Much Can I Save by Draught Proofing My Sash Windows?

By carrying out a full draught proofing on your home you could save on average £55 per year according to the Energy Saving Trust. By doing so you will benefit from not losing hot air from your home meaning you can turn down your thermostat or reduce your heating temperature, saving you another £65 per year. Imagine the effects on properties with sash windows as they experience bigger losses of heating, could they save even more?

Every Year the UK Would Save £180 Million Which Would Be Enough to Heat Nearly 930,000 Homes

The Energy Saving Trust also suggests that if every household in the UK was to carry out this procedure on their home, every year the UK would save £180 million which would be enough to heat nearly 930,000 homes.

So not only does it improve the energy efficiency within your own home but it reduces the consumption of the UK in general.

We have extensive experience of working on Listed property and heritage buildings and all works are carried out sympathetically in keeping with the history of your property.
