Transform Your Home With Beautiful Windows

When it comes to changing your casement windows, we understand you have a wide choice of options. So what makes us different? Well, we’ve been trading non-stop since 1991. We’ve transformed over 100,000 homes, and gained the coveted support of Trading Standards. We employ our own installers, don’t pressure sell and have a dedicated Customer Service department to look after you once everything has been finished.


Only The Best

Every window that we install is made to suit every individual customer’s home. We use industry-leading Kömmerling windows, the best energy-efficient glass on the market, and locks that will keep you and your family safe.

Our surveyors and installers are all employed by us, and many of them have been with us for well over a decade. We know how they work, and we are proud of their excellent workmanship. Lots of companies will replace your windows for you, but we’ll do it with care, skill and treat your home as if it were our own.


Casement Windows

Casement windows, also known as flat windows, are what most people think of when picturing a window. They are typical of many properties up and down the country, and we install hundreds of them every week. From a fixed window to a large bedroom window with multiple openings, we’re sure we’ll be able to design a casement window that’s prefect for you and your home.

As well as regular uPVC casement windows, we also offer a flush sash window that is designed to replicate the traditional, flush finish of timber windows but with the high-performance thermal properties of modern day uPVC. These are a new addition to our product offering, so enquire now if you’d like to learn more.
