Let us Transform your Sash Windows

We will use our 50 years of combined experience together with our proven double glazing system to upgrade your windows

Why replace your sash windows, when you can double glaze your existing ones?

You can preserve your existing sash frames and draught proof them with our revolutionary system.

Read how our founder, Phil Novell, created our unique double glazed sash window replacements

I was already successfully repairing and draught proofing sash windows back in early 2005.

But it seemed absurd to me that the big window companies were tearing out perfectly good box frames when they could be preserved. So I collaborated with a skilled joiner to develop a revolutionary system.

Our system not only effectively draught proofed the windows but also allowed for the creation and installation of double glazed sashes (the sliding parts) into existing box frames (the main frame).

We even mastered a seamless method for replacing rotten windowsills, ensuring that even frames in disrepair could receive the benefits of new double glazing.

Through my own personal journey, I’ve honed the expertise and techniques needed to transform your sash windows into efficient, warm, and beautiful features of your home.

Join me in putting an end to the struggles of outdated windows, and let’s create a comfortable and inviting space for you and your loved ones.

With almost two decades of experience under my belt, my dedicated team and I have successfully converted thousands of single glazed windows into double glazed masterpieces.

What sets us apart is our unique approach—we accomplish this transformation without the need to replace the box frames.

This means that our customers can say goodbye to the hassle of replastering and redecorating interior walls, which would be necessary with traditional replacement windows.

We take pride in our expertise and the satisfaction of saving our customers time, effort, and unnecessary expenses. We have two decades of local experience and are members of FENSA.
