Crystal Windows

Crystal began trading in 1995 to provide replacement windows and doors and is jointly owned by its management, who provide day-to-day leadership. It has grown into a home-improvement business serving the South East, with more than 100 experienced staff and over 140,000 installations recorded on its current profile. Its range includes windows and doors, porches, garage doors, insulation, solar PV and other home-improvement products.

For windows, the company supplies made-to-measure units and carries out its own measurements and installations. It offers uPVC, aluminium and wood frames, including sash, casement, tilt-and-turn and bay windows. The site also lists bespoke window designs and door installations, and describes its double-glazing products as designed for energy efficiency, security and comfort.

Crystal states that its windows have an A+11 energy rating and advertises guarantees of up to 10 years. It lists double-glazing services in Essex, Kent, Hertfordshire, London and Surrey, and provides finance options through a panel of lenders, subject to status and affordability.
