Crystal Windows & Doors

Crystal was started in 1995 to offer a fair, honest and decent service to customers wanting replacement windows and doors. From small beginnings in Rainham Essex, the company and its new approach to business and customer service began to thrive and expansion was brisk. After many years of dedication and hard work, Crystal has become one of the longest standing and most trusted Home Improvement brands in the South East of England.

Crystal tilt and turn windows are functional engineering masterpieces. Originally they were designed for taller buildings or those with restricted outside opening space. These windows open inwards: either by a small tilt inwards for ventilation purposes or, a full 90 degree turn into the room, similar to a residential door.
