Traditional timber windows and doors

Beautiful wooden window and doors

Are your windows or doors rotten or letting in the cold weather, resulting in high heating costs? Operating out of our factories in Berkshire, we manufacture and install energy efficient new sash windows, wooden casement windows, external French doors, timber Front doors, Stable doors, Sliding doors and Bi-fold doors.

We also supply and install secondary glazing and new sashes into existing frames (replacing just the moving parts) for timber windows. Our repair services comprise draught sealing and minor repairs.

The majority of our replacement wooden windows and doors are double glazed. However, we can also manufacture single glazed windows and doors, or use our heritage glazing, where standard double glazing is unlikely to be approved (listed buildings and some conservation areas).

We use a timber called Accoya, as standard, which is highly durable and stable. Accoya is a sustainably sourced timber which comes with a 50 year anti-rot guarantee.

All our new windows and doors come fully factory finished and are draught proofed to further improve the soundproofing of the windows and improve the energy efficiency.

OUR RANGE

SASH WINDOWS

TESTIMONIALS

I am extremely satisfied with all aspects of your service – from the initial enquiry and surveyor visit, to the quoted price of the window and its installation. I will be using The Sash Window Workshop again for future replacements.
