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.

We were very pleased with the service received from Advance Glazing Systems. The fitters were very hard working, polite and helpful. They did a reasonable job of cleaning up afterwards and we were surprised that so little touching up was required by us after the windows and door were fitted. The office were very helpful when we requested a slight amendment to our order and they did everything they could to accommodate us.

I contacted John after my front porch door had been burgled, realizing old porch needed replacement ASAP to be made safe. I got same day design, quote and the nearest installation date possible given parts are custom made. The team arrived on time, were really nice, worked hard and finished everything to very high quality, leaving everything clean and tidy. The team then returned after 2 weeks to also replace the kitchen window - which was not that urgent. I like the look of the new porch and feel much safer now at home - thanks so much John, Julie and the team for a job well done at a time that I really needed it.

Highly recommended (Replacement gutters and windows)

We had replacement gutters, fascia and windows fitted for our 1920's semi-detached house which has bay windows. The contract was part fulfilled prior to the COVID19 lock-down but some of the work had to wait a few weeks. AGS kept us up-to-date through the process. All work has now been completed to a high standard. We're very happy customers. Dealing with AGS has been a pleasure throughout the process. From initial visit (no hard sales pitch and their quote was quite competitive); to survey/measurements (where they proactively sought to resolve issues) to arranging scaffolding (being flexible with the dates )... the office were very efficient. For the fitting...One team was used for the gutters/fascia and another for the windows. Both teams worked efficiently and were very tidy - keen to make everything "just right". We highly recommend AGS.

I used Advanced Glazing Systems to supply and fit a double glazed side door. They were professional from start to finish and did a fantastic job, and very reasonably priced. Having used another local company on previous occasions I wished I had know about AGS before as they were far more trustworthy, helpful and knowledgeable! I would certainly recommend them!
