What Makes Us Different?

We like to think that our many years specialising in purely sash windows, we have a good handle on what makes perfection.

Continuous Innovation

Dedicated to retaining the elegant proportions of traditional windows through continuous innovation, creative flair and passion, you can be confident we set extremely high standards with excellent craftsmanship and attention to detail.

You’ll find we’re not cheap. Indeed we’d go so far as to say we’re considerably more expensive than other sash window producers. That’s because we include more, do more and taking like for like, you can expect us to be excellent value for money.

Exceeding Expectations

You set the standards with your own specification, the benchmark you expect your new windows to attain, using the components you require and that you believe are right for your project. We will help you understand what is important and set out to exceed all expectations.

As conservation officers across the UK have found, if you decide to invest in our products, your perceptions of PVC-U will probably change for good.

What People Say…

“I’m always so impressed with the service from the entire team at masterframe. Recently, I called the office while I was with a customer. I needed some information quickly, to help me to close an order. With an average window supplier I wouldn’t usually make this call, as typically I can wait hours or even days for the right information, but I knew masterframe would react straight away with the right information. In this instance carol and jane between them had an email over to me within minutes, and my customer was very happy. Top quality service from knowledgeable staff as always. Thank you!”
