Draught proofing sash windows


Box sash window draught proofing.

An overhaul and draught proof of box sash windows, casement windows and doors, is the most effective way of allowing your windows to be energy efficient and still work as they were originally intended, without the need for replacement or  uPVC double glazing.

What we do to draught proof your sash window

A general overhaul and draught proof includes all minor repairs, re-cording and making sure the windows are balanced, fully operational and draught proofed. Any new timber will be treated and under coated, and the window will be made ready for decoration.

How we draught proof sash windows

To overhaul and draught proof a box sash window we remove both top and bottom sashes. We then machine a groove in the top of the top sash and in the meeting rail of the bottom sash, and then install a weather pile into these groves. Once this is done we replace the parting bead and staff bead both of which have the weather pile pre-installed.

We replace the cord with a traditional style cord that is pre-waxed and pre-stretched. The weights will also be altered if required, in order for the sashes to operate in the correct manner.

The window will then be put back together with traditional style window furniture to finish it off.

To overhaul and draught proof casement windows and doors we remove them and plane the window or door to suit and allow for the weather pile. We then run a groove all the way around and install the weather pile.

In addition to this, where possible we fit the weather pile in to the frame of the window or door to create an extra seal around them. We will also replace the hinges and handles if required.

Call us on 0800 756 6389 or book a draught proofing window survey.
