Very professional from pre survey through to installation. Team 3, Davie, Bryan and Liam arrived on time on both days ( 8 windows being fitted) and worked non stop, were polite and explained each stage of the process. Despite it being the two coldest days of the year they worked inside and out without complaint. On completion they hoovered up the mess ( not too much as they put down dust sheets before starting ) and demonstrated each window. There are a couple of areas of render needing repair and the office has been on the phone already to make an appointment. Altogether very pleased, would not hesitate to recommend CSJ and team3
