This is the third time I have used this company and as usual the work was carried out in an efficient and competent manner from my first enquiry regarding the job and the completion. The company is a family run business and all members are pleasant and helpful from the office staff to the actual installers.

AGS replaced my windows and doors. The fitters were punctual, completed the work to a high standard left having tidied up afterward. Pleased with the product and service. There were a couple of small issues, which they returned to fix without any fuss. Very impressed with AGS and have already recommended them to a friend and would use them again.

New Porch, Front Door & Monocouche Render
Customer Service

Absolutely amazing. Has completed changed the front of our house from half ugly old render, old flat roof porch falling apart and old sliding glass door and wooden 2nd door. House now looks beautiful in chalk white render, chartwell green front door, pitched roof porch. We already had the windows and back bifold done 6 months prior by Andy and his AGS team. They were best price and done the best work then. So asked if they done porches/render as well as front door after some disappointingly high quotes elsewhere from more builder based companies. Yet again AGS come out best on price, Andy as detailed as ever, his building team done an amazing job, worked so hard and in 8 solid work days changed the front of our house into something looking brand new. Outstanding. Having never liked quotes and work being done but have been absolutely chuffed to bits we found AGS. They should really call themselves advanced fanatical home improvements as so much more than glazing.

We have used AGS a few times before and didn't regret using them again to complete the rest of the house. They did an excellent job, four large windows, one a bay, and a front door. The whole process from first call to completion was great.

I am very satisfied with the work done by AGS. From the initial phone call to the after work service, I have been communicated with professionally, the work has been done to a high standard, receipt and after service documents provided swiftly. I've got no complaints at all and would not hesitate to recommend AGS for any window replacement work.

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!

Even though we had our windows fitted over 3 years ago we had a problem with smears appearing inside a couple of sealed glazed units. No problem, AGS replaced them! Excellent service.

I have used them on a couple of occasions before for whole house double glazing. They were by far cheaper than the multinationals and a better product. Also gave a 10-year guarantee. We had this house double glazed including bi-folding doors in 2013. Our neighbour was looking for a cheap supplier but was so impressed with the work being done on ours she had her whole house done too by AGS. We needed a garage side door replacing from wood. Should have done it in 2013! Still the same efficient family-run company. Would thoroughly recommend.
