I've had to deal with a lot of companies in the last few months and AGS have been one of the best. A terrific experience from the beginning to the end. I would recommend them very much if you need a new front door.

From start to finish everything was as promised. Survivor came on time, fitters came on time, job finished. The workmen were polite, tidy and got on with the work. John was an excellent initial contact, answering my questions immediately. It was a pleasure doing business with this company

Bay Windows Front Door

New Bay windows and Endurance Front door fitted by AGS. The fitters have been amazing, they were very helpful in selecting and recommending ideas. The surveyor was brilliant, worked everything out perfectly. Could not find a fault if I tried. Everything finished to a high standard. They have totally transformed the House . Flush sash windows in white woodgrain with Heritage sills. Definitely worth the extra money, they look like the original windows that would have been fitted when house was built. If everyone had these done the road would look fantastic. So pleased am getting rest of house done. Well done AGS.

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.

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.
