I have used C-thru 3 times; to replace all our gutters, replace two external doors and then to replace 13 windows and a large glazed door. Every time, Stuart has been the best quote, most willing to meet my design requests and nicest person to deal with. The quality of the work is very high, Stuart and team are professional and polite and the results of he work are so good that several other houses on our road have since booked C-thru for similar jobs that have also been completed to a high standard. When having our windows and glazed door quoted for, both other companies that quoted told me they did not think my design choices would look good and both were inflexible about what they were willing to do. They wanted to fit exactly the same outdated style of window that was being removed. I wanted modern windows with larger panes of glass and fewer sections in each frame. Stuart at C-thru trusted that I knew what I wanted for my own home and did exactly what I asked for. He also went out of his way to speak to the manufacturer when I asked for an unusually large glazed door. He managed to get the manufacturer to add additional hinges to take the extra weight and managed to fit a beautiful door which I have had absolutely no issues with since it was installed. We have had so many compliments about the new windows and even had people knock on the door to ask who fitted them. I could not be more pleased with the service or the results.
