After using AGS in the past for windows and front door 4 years ago, they were the obvious choice when we were doing a kitchen revamp and wanted a back door and a window put in. The first point of contact was John and he was very helpful and obliging and said they would fit us in within our time scale. Darren & Gavin the fitters arrived on Saturday morning to cut out the brickwork and fit the new door and window. Both guys where very professional, clean and tidy in their work. New door and window looks a treat, very happy.

Really pleased with our new windows from Advanced Glazing, they look incredible in situ and really change the whole vibe at the back of the house. Inside is already noticeably warmer, quieter and lighter! The decorative architrave around the windows is stunning and I love the colour outside! John really understood our brief and delivered everything I was hoping for... and for such a good price. The fitting team were absolutely lovely and really did a fine job - they were a pleasure to have in the house. All of the team were a pleasure to deal with from start to finish - I will definitely be using them again when I have the money to do the front of the house!

We have used AGS previously, replacement French doors and a new external door, so we chose to use them again and once again they delivered a great service, from the my initial phone call to completion of the work. Highly recommended, we will be using them again to complete our work at a later date.

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.

We have an old house and the original small conservatory was becoming dilapidated. We decided to replace it with a larger one. We chose Advanced Glazing Systems after careful research and a site visit. The work was carried out by their regular builder, Alan Fernee, of New Space Developments. We are entirely happy with the product and the workmanship involved. Everything was done carefully and with due regard to the disturbance that was inevitable in such a project. We fully recommend both the product and the builder.

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.

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.
