McDermott Windows allow you to tranform your home to suit your individual taste

uPVC Windows from 2 Leading window frames

Whatever the style of the home, our window design blends in beautifully. Choose from casement windows, bay or bow casements, and ‘tilt and turn’ windows enable easy cleaning from inside.

You can even have windows and doors to match both your interior and exterior décor – for instance, a clean white finish on the inside and Rosewood or golden oak colour on the outside.

With our choice of window frames you not only get a slim, stylish and attractive window frame, but also a product that incorporates all the benefits of modern uPVC, whilst preserving the appearance of traditional timber frames.

A traditional look can be achieved with the addition of external Georgian bars. The choice of glazing is huge, with leaded and even bevelled for true aesthetic appeal.

Energy Rated Windows

All our products have been designed with energy efficiency in mind, stopping heat from inside your home escaping, while allowing heat from the sun into the room: the result – savings on fuel bills and reduced energy waste.

We install BSI Kitemark Energy Ratings (WER) windows, with A, B & C ratings available. For every order that qualifles for an energy rating, a certificate is issued by us so that, so you can feel safe that you’re getting a genuine product.

Choosing the right replacement windows can help make your home more energy efficient and reduce heating costs. All our window systems can achieve an ‘A’ rating (A rated windows) – the highest energy rating and when installed with the appropriate glazing unit, double glazed windows from us comply with the latest building regulations.
