A Window Is Not Just A Window

Capital Windows bring over 3 decades experience in the manufacture, supply and installation of replacement windows.  Unlike many other window companies we offer a choice of materials and window options.  Having carried out thousands of installations we know that every property is different.

A reputable and experienced window company needs to be able to advise on the right choice of products that are right for you, your home and your family.  A window is not just a window. We are one of only a few expert window companies that can provide the style of windows to suit your property.

Traditional houses often call for more rounded and softline profiles.  Contemporary extensions often require flat line and more modern looking windows with the right aesthetics inside and out.  Colour is also hugely important as is design.
