The difference between a fitted job and a fitted-looking job is the setting out. For timber casement windows in your home 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.

Timber Casement Windows — common questions
What is the difference between flush and stormproof casements?
A flush casement sits within the frame so the face is level — it is the traditional look and correct for period and conservation work. A stormproof casement overlaps the frame with a weathered lip, which sheds water better and is a mid-century onwards detail.
How long do timber casements last?
In Accoya with a factory finish, fifty years plus with routine maintenance. In unmodified softwood, twenty to thirty. The failure point is nearly always the bottom rail and the sill where water sits.
Can you match the existing opening pattern?
Yes, and in a period property you should. Which lights open, where the mullions fall and how many panes there are is what makes the elevation read correctly.
What ironmongery do casements use?
Either traditional peg stays and casement fasteners, or concealed friction hinges with espagnolette locking. Traditional looks right; friction hinges are easier to seal and give you an egress-compliant opening where a fire escape window is required.
Will they meet current building regulations?
Yes. We specify glazing and frames to the required U-value, provide trickle ventilation where the regulations call for it, and size at least one light per habitable room for means of escape where needed.
Can casements be made in a curved or arched head?
Yes. Segmental and semicircular heads are made from laminated sections so the head does not have short grain. It adds to the cost and the lead time.
Do the windows come painted?
They can come primed for your decorator, or fully finished in the workshop in any colour. Factory finishing is far more durable — the coating is applied to all six faces including the ones you cannot reach once fitted.
How much disruption is there when replacing windows?
One to two windows a day, each open for a few hours. We make good the internal reveal and the external pointing; redecoration of the reveal is usually needed afterwards.
