About Cosyseal Double Glazing Ltd
Cosyseal provides planned window and door replacement projects and reactive repairs. It has worked in double glazing for more than three decades, serving housing associations and social landlords across London and the Home Counties.
Its services include uPVC, aluminium and timber windows, secondary glazing, fire doors, composite doors for homes and communal doors with entry systems. The company also repairs windows and doors and offers window maintenance contracts.
For replacement work, Cosyseal offers a free, no-obligation quote and carries out a detailed survey. Windows are made in Britain and fitted by directly employed teams. Installers explain how to operate and care for the new products, take away old windows and doors for recycling, and leave the home clear of installation mess. Window and door replacements carry a 10-year parts and labour guarantee covered by insurance.
