Select the styles that suit your property: casement for broad versatility, flush sash for a heritage look, sliding sash for period elegance, tilt & turn for flexible ventilation and easy cleaning, plus bay and bow configurations to maximise light and space. Every window is made to measure for a seamless fit.
Personalise with popular colours (e.g., Anthracite Grey, classic whites, lifelike woodgrains) and coordinated hardware. Glazing choices include privacy, decorative, leaded or Georgian designs; add astragal bars for traditional character or keep lines minimal for contemporary builds. For acoustic comfort near roads or schools, specify laminated or specialist sound-reduction glass to help keep interiors calm.

Great products demand skilled fitting. Our trained installers provide professional installation to current Building Regulations with FENSA-registered compliance. We handle precise measurement, careful removal of old frames, squaring, packing and sealing of new units, and thorough finishing—protecting surrounding plaster, render and décor. Security options include multi-point locking and child-safety restrictors where required; trickle ventilation supports healthy airflow.
