We had quotes from several traders for new windows. John from AGS came to our house, was relaxed, left plenty of brochures, no hard sell and followed up when he said he would. Other companies quoted two to two and a half days for job. We decided to go ahead with AGS and are glad we did. Clean friendly staff from start to finish. Fitters sheeted all rooms, stairs and walkways for a clean job. Fantastic new look to the property and all completed in one day. WOW. Already had good comments from our neighbours and only fitted yesterday. Thoroughly recommended trader. Even when I called to pay the balance, Julie was friendly and informed me again or the service call out if any problems and would be dealt with in 1 day. An absolute delightful company. One that others could learn an awful lot from but I am glad they haven't. Thanks again for a fantastic job well done.

Andy and Peter, the surveyor were both a pleasure to work with. Very patient and explained all the costs involved very clearly. The installation was completed in the time stated and they were very clean and tidy.

Last year this company installed a porch for me. I contacted them for French windows. The work was professional, affordable & just what I wanted. I will use them again.
