Durham is a county of stone-built pit-village terraces alongside Georgian and Victorian city stock. That is exactly the kind of building stock a sash window has to be drawn around, so we allow for it at survey stage rather than on fitting day — walls get checked for wind and plumb, floors for level, and the setting-out is taken from the worst reading, not the best.
How we approach it
We build timber sash windows as cabinetmakers rather than fitters: machined joints, real carcass construction, and a finish applied under workshop conditions before anything reaches your Durham address.
How we build it
Timber is chosen for the room it is going into. Painted work is built in tulipwood and moisture-resistant MDF because they hold a crisp arris and take a sprayed finish without grain rise. Where the grain is meant to be seen we use European oak, walnut or ash, with veneers laid so the figure runs continuously across a set of doors.
Finish and materials
You can have it primed for your own decorator, sprayed in any RAL or heritage colour, or left in oiled timber. Oiled finishes can be refreshed at home; sprayed finishes are harder wearing and are what we recommend for kitchens and anything at knee height.

Straight answers
Timber Sash Windows in Durham — common questions
Can you match the original glazing bars?
Yes. We match the bar width and profile from the original. With double glazing, a true divided bar with individual small units is the authentic route; a bonded bar with a spacer inside is far cheaper and reads correctly from the street.
Is it cheaper to repair the existing sashes?
Very often, yes — see our sash window restoration service. If the boxes are sound and only the sills and bottom rails have gone, repair is usually the better value and keeps the original glass.
Do I need planning permission or listed building consent?
In a conservation area, replacing windows usually needs permission and the replacement must match the original. In a listed building you will need listed building consent. We can supply drawings and a specification to support an application.
How draughty will they be?
A new sash with brush seals in the meeting rail, staff bead and parting bead is not draughty at all. The draught in an old sash comes from a worn rebate, not from the design.
Do I need to empty the room before you fit?
Clear the working wall and anything fragile. We bring dust sheets and a vacuum-extracted saw, but fitting makes dust and we would rather your furniture was out of the way. For kitchens we will agree a sequence with you so you keep a sink and a kettle for as long as possible.
