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.
