Casement windows for Portsmouth homes
Casements are the standard replacement across the interwar and postwar stock of Cosham, Paulsgrove and Drayton, and on the rear elevations of the Southsea and Fratton terraces. A flush-sash casement suits the older island streets better than a lipped frame.

Frequently asked questions
What is a flush casement window? One where the sash closes level with the frame - a more traditional line for Portsmouth’s Victorian streets, at roughly 10 to 15% more.
Do casement hinges last near the sea? Standard ones corrode faster - ask for marine-grade friction stays on any elevation that faces the weather.
How much are casement windows in Portsmouth? Around £361 to £927 per window fitted, using the local 1.03x cost factor.
