Renewal of double glazing
AGS have just renewed all our windows and doors apart from the front door which we’d had done a couple of years ago. We would definitely recommend AGS. Andy’s quote was straightforward with no messing about and didn’t take hours like some companies. Once we’d accepted the quote the surveyor came to measure up, everything was ordered and we very quickly had an installation date. The installation team arrived early on the planned day and worked hard. The job was finished in three days as promised at the beginning even though three panes of glass had broken at the depot - these were ordered and arrived in time to be installed without the job being delayed. The team were friendly, worked hard and cleared up very well each day. We were impressed with the attention to detail given to the job.

Efficient, tidy, great quality and excellent service from start to finish.
Once Andy and Tyler walked through the front door I sensed professionalism. My wife and I talked through what we would like installed, being 5 windows and a new front door, all in uPVC and the windows being sash. Andy explained everything from the window design, a sample, to how best the installation could be done, clarifying with his surveyor on the phone whilst with us. The date for install was set and met and the installation completed in 2 days. The work was brilliant, the mess, non existent. The guys cleaned up as if they'd never been here. Brilliant company and highly recommended

Quality Service from a Professional Family Business
The replacement UPVC double glazing units for the front and back of our house totalled 11 units, including porch doors, flat and bay windows, and a back door. The work was completed in 5 days by Carl and Jordan, who work well together, and were professional in ensuring a quality job with the minimum of intrusion. They responded rapidly to an unforeseen problem when taking out one of the old windows. From the commencement of our enquiry to the company, we found the responses from Andy Barnett to be concise and prompt, and in the administration department, Ella was knowledgeable and friendly. A well-run and efficient family business, who put service and quality (at a reasonable price) first, and they are worthy of being a Which Trusted Trader. Thank you and well done. We are pleased to recommend Advanced Glazing Systems.

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.

One word describes my dealings with AGS, EXCELLENT
First contact: Phones are answered promptly by polite, efficient, knowledgable members of staff. I found their prices very competitive. The products are good quality. The surveyor and fitter did an excellent job, making good all areas and even vacuuming up the small amount of mess, 1st class.

Surpassed our expectations
All new doors and windows fitted. We found this company excelled in all services it provided. We had spent several weeks asking numerous questions about product design, efficiency, alternatives such as acoustics and laminate glass, size, design, seals and gaskets, trickle vents, creasing tiles, door handles and locking mechanisms. The company was very patient answering all our inquiries, was able to provide detailed information to support quality of products so that we could check for our peace of mind. Installation was very efficient and staff courteous and professional. Work carried out to agreed schedule and accommodated our own work commitments. All completed within budget and no hidden costs. What we were particularly pleased about was accommodating our special request to have our kitchen window sprayed black on the inside whilst remaining white on the outside, which is not standard and required third party involvement which the window company dealt with directly. In summary, we would highly recommend this long established family company who really go the extra mile to ensure a first class experience.

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!

WONDERFUL FLUSH FITTED WINDOWS
Really very pleased with the quality of our flush fitting windows. The fitters arrived on time every day and took all old windows away, they were always helpful with any issues we had. Would definitely recommend Advanced Glazing Systems.

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!

100% satisfaction on all aspects.
On 04/02/10, we had the windows and door replaced by AGS and were very impressed by the professional way our order was taken with help, then the very high quality of materials and fittings. On 30/09/15 we chose AGS again to fit windows and door to a new extension on rear with same full satisfaction.
