AGS were replacing windows in a nearby house and I was impressed with the work, so decided to contact them to get a quote for replacing the windows in the two front rooms of my 1st floor maisonette. I telephoned the company and the fitters working on the nearby house came the same day to measure the windows. I received a call from AGS the following day, followed a little later by a further call with a quote which was well below what I thought I would need to spend on the work. Two fitters arrived at 8.30 a.m. on the chosen date and the work was completed by midday. Everything was left clean and tidy and there was no damage whatsoever to the existing windowsill paintwork. The two fitters didn't even take a tea break when tea was offered! I am delighted with the windows, which add greatly to the appearance of my maisonette.

Can't praise this company too highly. Expertise second-to-none. Their work ethos is exemplary. Arrived on time, removed the old front door, fitted the new double door, tidied up as they went along, so no mess. Demonstrated how the lock worked, nothing too much trouble. I have used them before to fit double-glazed windows, so expected nothing less than perfection, which certainly was confirmed. I would have no hesitation in recommending them for customer service, quality of workmanship and value for money.

We had quotes from several traders for new windows. John from AGS came to our house, was relaxed, left plenty of brochures, no hard sell and followed up when he said he would. Other companies quoted two to two and a half days for job. We decided to go ahead with AGS and are glad we did. Clean friendly staff from start to finish. Fitters sheeted all rooms, stairs and walkways for a clean job. Fantastic new look to the property and all completed in one day. WOW. Already had good comments from our neighbours and only fitted yesterday. Thoroughly recommended trader. Even when I called to pay the balance, Julie was friendly and informed me again or the service call out if any problems and would be dealt with in 1 day. An absolute delightful company. One that others could learn an awful lot from but I am glad they haven't. Thanks again for a fantastic job well done.

My wife and I have had new windows and doors supplied by John and his excellent team over the last few days. The service has been exceptional from start to finish. John attended and gave a very competitive quote compare with 3 other local and national companies. No lengthy sales pitch or discounts if you sign up now, just honest and competitive quote with no pressure. The products were made and fitted within 3 weeks. They are of excellent quality. Darren and Adam the fitters were the most friendly and helpful tradesmen we have ever used. They are prompt, tidy and highly skilled professionals. We are so please as other trades people have often disappointed. Advanced Glazing Systems Ltd did not disappoint. Kind Regards Andy and Jan

AGS was the first of three quotes I got for new front of house double glazing. I chose them because they were only interested in selling their product, not trying to sabotage the reputations of the other companies I got quotes from. Any questions I had at the time were answered, plus a few I belatedly thought of and emailed about, professionally and honestly. In the end their quote was also the most competitive. From saying yes, everything was done in two weeks, at exactly the price quoted. Highly recommend them.

John, the Director, was very knowledgeable and experienced in dealing with local council. He even helped us with planning application and was persistent with calling and going to council office to reason with planning officer and after months they finally approved! That's John! They organised scaffolding for all 3 flats in the building thanks to John co-ordinating the dates and it was all done with 12 windows (4 per flat) and a balcony door and all cleaned up in 3 days. The guys worked long days to get job done. Double glazed acoustic glass really keeps the noise out now. We don't hear a thing even when DLR train goes past. New windows and doors kept us warm, dry and quiet all winter. Cannot recommend John and his team more!

AGS Ltd carried out a prompt and professional service. From the helpful initial quotation service to the professional delivery and fitting of the windows, I couldn't have asked for better. The quality of the windows are exactly what I wanted - superb job!

Very happy with the service from AGS. Quote was very competitive and they were able to install a new kitchen door and window within two weeks of my placing the order, which was much faster than I had expected. They did a very neat job and left the kitchen clean and tidy. Dealing with them was easy with no pressure to buy. Originally asked them to quote based on the recommendation of one of my neighbours. Cover a reasonably wide area as we live in London N10

Small family company, no hassle sales pitch, sensible, honest, good workmanship. Took nightmare out of looking for double glazing company.
