Box Sash Windows by Alco Design


Preserve your home’s heritage and character by restoring your box sash windows.

Alco Design has over twenty five years of experience in reinstating box sash windows to their former glory. We have experience working on listed buildings and homes and have repaired many box sash windows across the Liverpool and other Merseyside areas.

Box sash windows – how they work

The operation of a box sash windows is down to the weight of the window, which is balanced by a heavy steel, lead or cast iron sash weight concealed within the box sash window frame. The sash weight is connected to the window by a sash cord, or sometimes by a chain, that runs over a pulley at the top of the frame.

Alco Design refurbishes existing box sash windows

As part of our specialist joinery services, Alco Design reconditions, repairs and renovates existing box sash windows by carefully removing the sash window from the frame and removing the ironmongery, reconditioning the wood if this is possible.

If the existing timber can’t be repaired, we will replace the old, or damaged timber, with new wood. We ensure that the new wood is carefully in-line with the existing profile of your window and treat it with specialist products to ensure that your sash window will resist hostile weather conditions.

We also repair and service existing sash cords and weights and ensure that your windows are operating smoothly before they are hand or spray painted using only the best quality paint. 

Draught exclusion for box sash windows

A useful enhancement to any box sash window is our draught exclusion system that will help you save money in your energy bills and eliminate those annoying cold spots in the room.

Added security for box sash windows

Security is a major concern these days. At Alco Design we can improve the security of your box sash windows by fitting specialist locks to keep out intruders.

Double glazing for box sash windows

Traditionally, box sash windows are single-glazed. However, using our new extra slim glazing units that comply with current building regulations we can install double glazing within your existing box sash windows.

New box sash windows made to measure

Where replacement of the sashes is not possible, Alco Design can install complete new box sash windows to your specification.
