Customer Testimonials

Excellent material and very quick, efficient and repairs and fitment of windows. Left the site very neat and tidy and and the workers were very polite. Will definitely be using you guys again.


As part of our refurbishment project we approached a number of suppliers for windows and bi-fold doors. We were recommended to discuss our requirements with Capital Windows by a friend and I am glad to have spoken to Ash to get the right advice and was quickly assured that we were speaking to the experts. We got all our new aluminium windows, patio door, internal bi-fold door and external door from Capital Windows and are very happy with the service and product. We would not hesitate to recommend anyone to this company looking for a good product for a great value. After sales services has been satisfactory as well.
