Sash window specialists for Portsmouth’s period properties
Original timber sashes are still common on Portsmouth’s older streets, and replacing them properly takes more care than a modern casement. Old Portsmouth and parts of Southsea carry conservation status protecting their Georgian and Victorian character, which is exactly the kind of area where sympathetic sash replacement or refurbishment matters most. As the historic home of the Royal Navy, the city’s identity and its tightly packed housing are both shaped by its naval past, so sash window specialists here need to understand both the mechanics and the look expected on these streets.

Frequently asked questions
Can I fit double-glazed sash windows on a listed or conservation-area property in Portsmouth? Often yes, but old Portsmouth and parts of Southsea carry conservation status protecting their Georgian and Victorian character, so slimline double-glazed units that replicate the original glazing bars are usually the way through rather than a standard modern sash.
Is it better to repair or replace old sash windows? If the timber frame itself is sound, draught-proofing and mechanism repairs are usually cheaper and can be enough. Full sash replacement makes more sense once the frame has rotted or the sash cords have failed repeatedly.
How long does sash window replacement take in Portsmouth? A single sash window usually takes half a day including making good the surrounding plaster or woodwork, though full-house jobs on larger period properties take longer.
