I wanted to use a local company, and buy British made. I tried 3 different Companies, and CGDC were the most competitive as well as stocking Garador (Made in Yeovil). They came out and did a quote, then came out again to make sure that everything was correct after I had accepted their quote (measure and measure again). Installation was easily achieved, and they took away my old scrap door. Came back a few days later to do final tweaks and finish off. Door works perfectly and is very quiet. I'd highly recommend these guys.
