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.

I would recommend AGS to anyone looking to replace their windows or doors. The work was carried out in the time frame stated and the fitters were very polite & tidy. Nothing was too much trouble for them either. We had a couple of problems after the fit and as soon as we phoned AGS someone came round to sort it out the very same day. My parents used them as well & they were so happy with the work done and with the price that was quoted.
