Why Replace Your Windows?
Replacing old or poorly performing windows can make a noticeable difference to the comfort, appearance and security of your home. Modern double glazing can help reduce heat loss and outside noise while giving your property a cleaner, more contemporary finish.
Improve Energy Efficiency
Modern glazing and insulated frames can reduce unwanted heat loss and cold draughts.
​
Reduce Outside Noise
The right glass specification can help create a calmer and more comfortable interior.
​
Strengthen Home Security
Modernise Your Property
New windows can transform both the outside appearance and internal atmosphere of a home.
​
Double-Glazed Units and Gas Options
The space between the panes of a double-glazed unit plays an important part in its thermal performance. Depending on the window specification, the cavity may contain ordinary air or an insulating gas such as argon, krypton or xenon, each offering different levels of efficiency, cost and suitability.

How Much Does Double Glazing Cost?
The cost of new windows depends on the number and size of the openings, frame material, window style, glass specification, access and installation requirements.
​
A straightforward UPVC casement window will generally cost less than a bespoke timber sash window or large aluminium glazing system.
The most reliable way to understand the likely cost is to provide the installer with basic information about the property and the windows you want to replace.
