What Our Customers Say

Pro-Line has been trading in West Cornwall for nearly 20 years. After many years of fabricating the 'REHAU' frames for ourselves, we decided to cease manufacturing and once again buy-in our frames from Dessian. I had no hesitation in renewing our friendship and ties with Dessian and have not been disappointed... John Elsey - Pro-Line Window Company, Penzance
