I am pretty clued up on DIY and some traders are reluctant or edgy doing work for people like me, not AGS, they understood that some jobs need the professionals. Every aspect of the job scored 100%.

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.
