Used Advanced Glazing for roof light and kitchen window replacement. Andy and his team were top notch from start to finish. We have used them twice now and also recommended them to friends and family. Always on time, great attention to detail and superb finish. We are chuffed to bits and would not hesitate to recommend.

Installation of a new rear window and door. This was the third time we have used this company and, as on previous occasions, their products and workmanship are first class.

This is the second time we have used this company as we had such a positive experience before. We had new windows installed to back of the house. All questions were answered, nothing was too much trouble. The windows were installed promptly and professionally and our property was left clean and tidy. So pleased with the quality of the new windows and the look. We would definitely recommend this company 100%.

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

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.
