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%.
