Window Warehouse is one of the most established window and door fabricators on the South Coast. We supply trade windows, doors and the Leka solid conservatory roof system to installers in and around areas including Portsmouth, Southampton, Bournemouth and Chichester. 

Starting out in 1986, we set out to manufacture the most energy efficient windows to replace draughty old ones in homes across Hampshire. We were one of the first companies to manufacture ‘A’-rated energy windows and we’re committed to developing new energy saving products to improve homes. Our latest exciting development is the Leka insulated solid conservatory roof replacement. 

We are the Approved Fabricator of Leka solid conservatory roofs and from our Portsmouth manufacturing facility, we supply to your local installers across the South Coast, Hampshire, Dorset, Buckinghamshire and the M25 circular into London, Kent and Essex.
