Fantastic Windows and Excellent Service!

I had a couple of Windows fitted in the first week of May by AGS. I experienced a professional, extremely efficient approach from the start and felt confident that the product I was ordering would be suitable for my requirements. The fitters were prompt and went over and above to make sure the work was perfect. There were no hidden costs (which I have unfortunately experienced with other companies in other trades) and what you see is what you get. I would highly recommend this company. Thank you again!

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.

I had a Conservatory which was falling down. Relatives and friends would not go in it. The trader replaced all the rotten woodwork and the single glazing, replacing it with double glazing, and put a new roof on. I now have a fabulous conservatory and cannot praise the company enough.
