Great service from start to finish. Andy was very helpful with lots of suggestions and his price was very competitive. Peter the surveyor was also helpful. Mark and Jordan were very fast and did an excellent job. They were also very good in cleaning up after themselves. Very pleased with the result and would have no hesitation in recommending them.

New front door supplied & fitted work well done & left clean & tidy. The glass we had chosen we thought was leaded light - but turned out not to be - contacted AGS who promptly fitted one that was.

AGS were totally professional from start to finish. Andy's quote was very competitive and the work completed by Gavin and Steve was first class. Everyone that I dealt with were polite, courteous and punctual and consequently I would have no hesitation in recommending AGS.

Everyone involved in this project (the installation of full double-glazing) was reliable, punctual, efficient, friendly and fully responsive to our needs. In addition to the standard units, John sourced a stunning decorative arched window, at a very reasonable price. Recommended without reservation.

We wanted to use a local trader, was told to try Advanced Glazing, which we are very glad we did. Very professional in what could have been an awkward installation. Over the moon with the results and will recommend AGS in the future.
