About This Project

Having spent more than 20 years specialising in windows, doors and conservatories in Milton Keynes, our team now branches further afield and caters to clients across Buckinghamshire, Hertfordshire, Bedfordshire and more. Most recently, they have been working on this fantastic two-phase project in Harpenden. Our wonderful client opted for upgrading several elements of their home, from their front door to all 12 windows – and the results are excellent!

Window, Roof Lantern & Door Installation - Harpenden

What We Did

After visiting our showroom and discussing the hundreds of options available, our client chose a combination of products by Formula One Range, Smart Aluminium and Diamond Composite Doors. They selected the shade, finish and handle type of each before our team arranged for all products to be custom-made to fit our client’s specifications.

The first phase of the installation involved fitting 12 white PVC windows by Formula One Range. This is, by far, the most popular window manufacturer amongst our clients, promising long-lasting durability, reliability and security.

Our FENSA-approved team returned to the property for a second day to install a bespoke Smart Aluminium roof lantern for the client’s new extension, along with a steel blue front door by Diamond Composite Doors.

This project is the perfect example of how updating your windows and doors can completely transform your property. To get started on your project, please do not hesitate to contact our experts in windows, doors and double glazing in Milton Keynes, Harpenden and many other areas.
