Cornwall is a county of granite cottages, fishermen's terraces and a strong second-home refurbishment market. 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
The difference between a fitted job and a fitted-looking job is the setting out. For timber sash windows in Cornwall we rod the job first, so what arrives on site already accounts for the bows, the skirting and the ceiling line.
How we build it
Moisture matters more than most people expect. Timber is conditioned before machining, and anything going into a kitchen, utility or bathroom is specified in materials that will not swell at the bottom edge. That is why the base of a well-made unit still closes cleanly after five winters.
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.

What happens next
Four steps, no surprises
Survey
A joiner visits, measures the opening, checks for level and plumb, and talks through how you want to use the space.
Drawings & quote
You get a setting-out drawing and a fixed written price. Nothing is ordered until you have approved both.
Workshop
Parts are machined, assembled and finished under cover while the site carries on with other trades.
Fit & handover
We fit, scribe, adjust and touch in, then walk you through care and adjustment before we leave.
Straight answers
Timber Sash Windows in Cornwall — common questions
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.
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.
How do I pay, and when?
A deposit at order to cover materials, a stage payment when the work leaves the workshop, and the balance on completion after you have inspected the fit. Everything is written into the quotation before you commit.
