The perfect finish every time

uPVC windows have been at the heart of our business for over 30 years. With more than 250,000 contracts under our belt and centuries of combined experience among our colleagues, our goal is for you to feel that you’re in safe and capable hands from start to finish.

We pride ourselves on our high standards and attention to detail. We install A-rated windows as standard, employ all of our own installers and have a rigorous quality control process. Knowing that the manufacture and installation is taken care of, we hope you’ll enjoy indulging your creative side; our windows are available in hundreds of styles and a wide range of colours. 

Our unrivalled product knowledge is backed by experience and a passion for what we do. We will listen to your reasons for replacing your windows, recommend products, carefully draw and cost each frame and send a quotation for your consideration. Whether it’s one window or a full house, a simple casement or a complex bay, chances are we’ve seen it before and can talk you through it.

A-Rated as standard

We won’t compromise on energy efficiency, comfort or warmth.  That’s why we install high-performance, A-rated windows as standard.

Security is as important to us as it is to you. Every window we install is incredibly secure, and our PAS24 option is the cherry on top.

Kommerling House

Kömmerling since 1991

We’ve been installing Kömmerling casement windows for over 30 years. 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.

Exceptional service

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

Committed to choice

Every window we install is made to suit each individual customer’s home. We offer a range of foiled finishes, from Anthracite Grey to Painswick. These are available in two different Kömmerling profiles, and are complemented by a broad range of high-quality furniture.
