Mill House Window Workshop

Wooden Sash Windows


Whether you're looking for a one-off sash window or to replace all the windows in your house, you should be able to find a manufacturer of sash windows here who can supply to your specifications and many also provide a window fitting service. Many of the manufacturers supply to the trade for either new build or restoration work.

Sash windows were traditionally made using softwoods such as red deal or hardwoods like oak, or a combination of the two. These days wood from a wider range of trees is used, some treated with new, more environmentally friendly timber treatments than were available in the past.

The sashes can be hung with traditional sash cord and weights or, especially for larger heavier ones, using spiral balances. Finishes include paint, stains and varnishes.
