I have had a few doors and windows fitted at different times this year and each time the company has arrived on time, the work has been carried out professionally. I would highly recommend this company.

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.
