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.

New Kitchen Door & Window

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.

Quality front porch & window replacement, good value, great service

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.

Conservatory replacement

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.
