Report
CSG replaced a patio door glass 8 years ago and have just replaced the other side of the door for little more cost than 8 years ago. Kept me well informed of when the work could be done and did an excellent job. Very pleasant people and would highly recommend.

Replaced a window in my shop. Came and measured same day. Kept in contact regarding glass being made as it was being made in Newcastle. Came to put it in and did an excellent job. Highly recommended.
