Customers consistently praise our tidy workmanship, professionalism, and clear, prompt communication from first quote to final fit.
I don't lightly give reviews normally, but I just feel that this company deserve one after completing seven windows and two composite doors. From the very outset from coming to give me a quote to finishing the work, C G windows have been consistently excellent. We are absolutely thrilled with the windows and doors, attention to detail and so clean. Fantastic product and an excellent price. Such a very big thank you to you and your team Cam, so polite and respectful. I would definitely recommend them

Highly recommend C G Windows. Cameren and his team (Dave and Lewis) were brilliant. We had seven windows and a new front door and cannot fault their professionalism and work. From the time of quote to installation they were brilliant. Thank you again.
