Ruislip Windows and Doors are a respected local installer specialising in replacement windows, doors and conservatories in both uPVC and aluminium. Based in Eastcote, Middlesex, we cover all local areas in and around Middlesex, Hertfordshire, South Buckinghamshire and North West London. Proud to be celebrating over 30 years in the business, the company was established back in 1986 by John Flynn, a City and Guilds qualified carpenter and double glazing installer. Originally trading as Ruislip Building Ltd, we became Ruislip Windows and Doors Ltd in May 1995 to better reflect our business.


As the company grew and became more experienced, we undertook increasingly more challenging contracts and our portfolio continued to develop and expand.


Now, over three decades since we first began, our installations range from the local domestic market to large commercial contracts.

Advances in the development of uPVC and aluminium systems, along with cutting edge technology and attention to detail now means there has never been a better time to experience the benefits that our home improvement products will bring to your home.

As professional installers with a reputation for quality and integrity, we choose our products very carefully, ensuring that our customers will benefit from the latest in technical and security specification. To this end, we install a range of products from trusted leading manufacturers, guaranteed to provide you with a top quality product that you will enjoy and benefit from for many years to come.
