Gwynedd is a county of slate-roofed stone cottages in quarrying villages and coastal holiday properties. That is exactly the kind of building stock a casement 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
Walls in Gwynedd are rarely square and floors are rarely level. A casement window that is built in a workshop to a nominal size will show every millimetre of that. We survey first, scribe on site, and finish so the joint line disappears.
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 Casement Windows in Gwynedd — common questions
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.
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.
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.
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 does a bespoke job take from order to fitting?
Most fitted furniture runs four to eight weeks from approved drawings to fitting day. Kitchens, staircases and timber windows are longer at eight to fourteen weeks because the components are larger and the finishing schedule is longer. We give you a date band at quotation and confirm the fitting week once the drawings are signed off.
