Timber Flush Casement Windows in Portstewart
The flush casement is the classic English window — the sash closes flat into the frame, giving a clean shadow line and a very period-correct face.
Homeowners across Portstewart come to us for timber flush casement windows after a uPVC replacement has aged badly. Timber is the material you specify when you intend to still be happy with it in twenty years.
What is included
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
- Kiln-dried to 12% moisture content before machining, so the sections stay true once they are installed.
- Stainless or solid brass ironmongery, because plated steel fails first and takes the finish with it.
- Glazing beaded internally, so the sealed units can be replaced without disturbing the external finish.
Timber moves. The craft in flush casements is anticipating exactly how much, in Portstewart conditions, and detailing the joints and finish so that movement never becomes a problem.

Questions
How do the surveys and quotations work?
The guide price tool gives you an indicative range in a couple of minutes. If that range works, we book a free survey — measurements, profiles, exposure, access — and issue a fixed written quotation with a drawing. Nothing is manufactured until you have approved that drawing.
What sort of guarantee do you offer?
Ten years on the joinery and the manufacture, and the sealed units carry their own manufacturer's warranty. Accoya frames carry the 50-year above-ground timber warranty from the material supplier. All of it is confirmed in writing with the quotation.
Will the timber warp or stick?
Not if it is specified correctly. Sticking comes from moisture ingress into unsealed end grain, or from solid stock used where laminated sections were needed. Kiln-dried timber, sealed end grain, factory finishing and engineered sections on longer spans between them eliminate it.
Can you fit trickle vents?
Where Building Regulations require background ventilation, we design it into the head of the frame at manufacture. That looks far better and performs far better than a vent drilled through a finished frame on site.
