We deliver peace of mind

We understand that you want to protect what you cherish the most, and that’s why our windows are manufactured to exacting security standards. If you’re interested in the best of the best, ask us about PAS24 accreditation, too.

We also understand the importance of choice. Choose from a combination of little top openers, full side openers, bottom openers and many more configurations. And when it comes to colour, texture and finish, we’ve a whole host of options for you to consider.

Mimic the timeless aesthetic of timber windows, choose slim sightlines for a more contemporary impact, or recreate the traditional appearance of Britain’s much-loved sash window. Our range of finishes includes English Oak, Anthracite Grey, Painswick and Grained White.

Exceptional customer service throughout

We employ our own surveyors and installers. In fact, some of them have been with us for more than 20 years and are very much part of the family. There’s no middleman – no contractors to deal with – just excellent service from time-served tradespeople.

We will replace your windows with care and skill, treating your home no differently than we would our own.
