Spectrum Glazing · Your home, considered
A better outlook, without losing your home’s character.
Replacing windows starts with the elevations you already have. For your Wivenhoe home, we look at opening sizes, the balance of glass and frame, and how you want each room to feel before narrowing down a material. The Wivenhoe Comp Door project began with an entrance that was no longer usable. For your own brief, separate essential improvements to operation and access from the colours and decorative details you would like.

Before you choose
Photograph adjoining windows together. Matching the height of transoms, the width of opening lights and the position of handles can make separate replacements feel considered. Tell us which rooms are difficult to ventilate or keep comfortable.

Compare the flush window layout and the patio opening in this Colchester installation. For your replacement, note which windows need to open, where privacy matters and whether surrounding frames will stay. Ask for the frame system, glass specification and making-good to be itemised in your quote.
