i used AGS last year to renovate my porch and was very impressed with the team, the price and the workmanship, therefore i have just used them again to replace all the window glass throughout my bungalow. I would and have highly recommended this company to others.

Lovely new front door

AGS were super helpful from the start. We have tried 3 or 4 times in the past to get a new fire rated front door (FD 30), glazed, with no success, but AGS made it a pleasant and straightforward process. From the initial consultation, survey and fitting, they took trouble to make sure we got exactly what we wanted. Looking forward to winter now, with no draughts, and lots of light coming in, we are so pleased with the door which has transformed our flat!

New composite door

I love my new door! My rep, Tyler, was so helpful in guiding me through the process, providing the clarification and info I needed in order to complete the spec for my bespoke door. He was endlessly patient with my to and fro calls and emails and the rest of the AGS team were equally polite, helpful and efficient. For both measurement and fitting, they came when they said they would and did what they said they would, and all so fast! I'd happily use AGS again and have recommended them to my friends. Thank you Tyler and AGS!

New door installations

I reached out to 6 door manufacturers and Tyler from AGS contacted me the next day. He came and showed us exactly what we wanted with samples and pictures etc. we had other quotes but AGS beat them all. I didn’t choose them for the price but the detail of Tyler’s visit to the accuracy of the new door being centered when it was originally offset. The door has now been installed and looks better than we expected and we are glad we chose AGS. The aftercare is excellent from Simone who constantly checked if we were happy with things even to the point of payment. Well done A+ service.

Great windows, nicely installed

I had aluminium windows installed by AGS and had a really great experience. From the first visit with no hard sell (which was very important to me), I got a reasonable price and they were accommodating when I changed my mind on one or two things. Their communications throughout were spot on. Their in-house installation team were friendly, efficient and experienced. There were a few anomalies with my old house which they cheerfully worked around. I am very pleased with the result and have nice, warm, sunny, draft-free rooms. I highly recommend AGS.

Fire escape window and Front door

Have now used Advanced Glazing on a few jobs,this job was for a rented property in Upton Park and council wanted us to get bedroom window changed to a fire escape window,as expected from first call to finish I would like to give 10/10 for the professionalism from staff that took the call, the Surveyor and the fitters. I had a call from the tenants once the work was done to say how pleased they were with the work and were so surprised with the tidiness of the fitters,they left the property spotless and were so polite.Would not use anyone else as even the after sales is absolutely fantastic.
