Advanced Glazing Systems (AGS) provided a seamless, efficient, effective service from quotation to installation. The aluminium windows, door and integrated window blinds ordered for the three flats in our building were competitively priced and manufactured and installed to a very-high standard. The installers, Mark and Jordan, were excellent ambassadors for AGS managing the project with speed, precision and skill. Our sincere thanks to AGS - highly recommended.

Excellent service from day one. Took the time to listen to what we wanted. Gave us a great price and there was no hard sell with AGS as there was with other Double Glazing companies. Did a great job installing double glazing to replace all the doors and windows in our house. I would definitely recommend 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.

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.
