Once you have selected a window style, the next step is to customise the window to your liking. We have a superb array of coloured finishes, glazing choices and exquisite hardware for our impressive window suite.

A colourful array of stylish finishes...

Choosing a window colour is as important as selecting the actual window design. You may not want to veer too away from the original coloured window you had installed so take your time to assess all the options to enable you to locate a suitable replacement finish. Our colour palette is extremely broad so the chances are that you will find something that works and will reinvigorate your home once the new windows have been integrated into the property. You can even have a dual-colour finish.

Glazing comes in many different forms…

When returning home and closing the front door behind you, it’s only right to expect a certain amount of privacy, but it’s sometimes never as simple as that. If you feel somewhat exposed even when indoors then perhaps think about installing privacy glazing as it will limit what people can see as they look into your property from the outside. Despite its purpose, you can still expect a generous amount of natural sunlight to force its way through the glass during the day.

Meticulously crafted handles...

Our traditional and contemporary-styled handles have been lovingly made by expert craftspeople and will make opening and closing your new windows effortlessly simple and forever pleasurable.

Built into each individual handle is a secure locking system that will keep the windows securely fastened.
