Belfast is a county of red-brick Victorian terraces and generous interwar suburban housing. 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 Belfast 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
Hardware is specified to the weight it is carrying, not to a price point. Soft-close runners are rated for the drawer load, hinges are adjustable in three planes, and sliding gear is sized so a full-height door still moves with one finger a decade later.
Finish and materials
Finishing happens in the workshop wherever possible. Sprayed paint gives an even film that brushwork cannot match, and the only work left on site is the final touch-in around scribes and fixings.

Straight answers
Timber Casement Windows in Belfast — common questions
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.
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.
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.
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.
Can you match existing joinery in the house?
Yes. We take a profile of the existing skirting, architrave or door and either match it from stock cutters or have a cutter ground so the new work runs identically. Matching an old paint colour is straightforward; matching aged oak takes a sample panel and a couple of attempts, which we build into the programme.
