WINDOWS

Advances in the development of replacement window systems means that the ability to retain the character of your home is much easier to achieve than it ever was previously. Period properties can now enjoy the benefits of modern replacement windows that are hard to differentiate from the originals. Woodgrain effect foils look just like painted wood and are available in an infinite number of colours.


We specialise in Conservation Areas and install only top quality products from trusted names such as Interfusion Timber, Smarts Aluminium, AluK, Kömmerling and Rehau uPVC,  ECOSlide by Victorian Sliders and our premium Residence Collection. Windows from across our collections combine good looks with enhanced security features and are thermally efficient, usually attaining at least an A rating.
