We ordered 9 UPVC windows (2 triple glazed and 7 double glazed) and 1 UPVC front door (all Rehau). They were professional and patient, answering any questions we had such as u-values, timescales and process. On the day of the install the workmen arrived and explained in detail the roadmap for completing the job i.e what would be accomplished each day and what to expect. It was a 3 day Job, they worked hard throughout each day. They kept us informed every step of the way and guided us around the finished product to check we were happy with the work. I would highly recommend SGS to othersVerified reviewerJob location: TS16- MMark S
