Heritage windows


Ruislip Windows and Doors Ltd are a respected local installer specialising in replacement windows, doors and conservatories in both uPVC and aluminium. Based in Eastcote and Watford, we cover all local areas in and around Middlesex, Herts, South Bucks and North West London and now throughout South East England. Proud to be celebrating over 38 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, almost four 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 window and door 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.



Fantastic Windows, Professional Service, Great Price.

"I can't recommend Ruislip Windows and Doors highly enough. Top class, professional service from start to finish. From the initial surveyor visit where there was no hard sell, just good advice on types and styles of windows and no pressure to place the order, to amazing glaziers who came and fitted 8 windows in less than 2 days. And on top of that a very competitive price. An all round great experience and fantastic customer service. Thank you so much, I am so pleased with our new windows."
