My wife and I have had new windows and doors supplied by John and his excellent team over the last few days. The service has been exceptional from start to finish. John attended and gave a very competitive quote compare with 3 other local and national companies. No lengthy sales pitch or discounts if you sign up now, just honest and competitive quote with no pressure. The products were made and fitted within 3 weeks. They are of excellent quality. Darren and Adam the fitters were the most friendly and helpful tradesmen we have ever used. They are prompt, tidy and highly skilled professionals. We are so please as other trades people have often disappointed. Advanced Glazing Systems Ltd did not disappoint. Kind Regards Andy and Jan

Fantastic New Windows Installed
Customer Service

We had quotes from several traders for new windows. John from AGS came to our house, was relaxed, left plenty of brochures, no hard sell and followed up when he said he would. Other companies quoted two to two and a half days for job. We decided to go ahead with AGS and are glad we did. Clean friendly staff from start to finish. Fitters sheeted all rooms, stairs and walkways for a clean job. Fantastic new look to the property and all completed in one day. WOW. Already had good comments from our neighbours and only fitted yesterday. Thoroughly recommended trader. Even when I called to pay the balance, Julie was friendly and informed me again or the service call out if any problems and would be dealt with in 1 day. An absolute delightful company. One that others could learn an awful lot from but I am glad they haven't. Thanks again for a fantastic job well done.

The service was fantastic throughout the whole cycle. We received a great quote which had not been inflated and didn't feel pressured at all. Once the windows were ordered we had a very experienced and knowledgeable surveyor attend the house. He gave good practical advice and really added value to the process. Once we were ready to install the team of two arrived. They were again very experienced and friendly just like everyone else had been. The experience and knowledge really helped for the little things that happen on the day. All in all we found the whole company and employees of the highest standard and would recommend to others.

Superb from start to finish. Gave realistic and competitive quote on day one with no "wheeling & dealing", Special offers etc, etc. Explained window specification and they were as described when fitted. Quick turn around, very prompt installation and very professional and friendly fitters.

After meeting such awful double glazing salesmen who quoted ridiculous amount, AGS was a breath of fresh air. The job was done to perfection and the price was amazing. In my view the best out there.

From the initial contact with AGS, Andy turned up on time and very knowledgeable and went through the product and our requirements, which was very useful and we changed our opinion, for the good, on a couple of things. We agreed price, surveyor turned up within a week and windows were ordered. The fitters turned upon time, were punctual, tidy and professional pleased with the fitting. I have already recommended them and would have no issues with using again, if need arises.
