AGS was the first of three quotes I got for new front of house double glazing. I chose them because they were only interested in selling their product, not trying to sabotage the reputations of the other companies I got quotes from. Any questions I had at the time were answered, plus a few I belatedly thought of and emailed about, professionally and honestly. In the end their quote was also the most competitive. From saying yes, everything was done in two weeks, at exactly the price quoted. Highly recommend them.

An excellent company, prompt, professional and clean. No over the top sales jargon, their straight price given was price paid. Not pushy. Workmanship great, any minor faults found by the company and rectified straight away. Extremely tidy workers and finished within estimated time. Would certainly recommend 100%.

Excellent product fitted professionally, on time and for price quoted. Used this company because they gave good references and a good price - with none of the ridiculous discounts/offers we got from the bigger companies. They, the big boys, could learn how to get business from this company - who gave a fixed price after a short visit instead of a whole evening's hard sell we got from the big boys!

Reliable and friendly staff. Professional company that listened to what I wanted and ensured I got this and was happy. The quality of the workmanship was outstanding and friend and family have also been impressed. Will use again in the future when I want a conservatory installed. Would recommend and very impressed with the service.
