Andy came to our home to provide a quote for our front windows. We were very impressed with this professionalism and went ahead. The two guys who installed our windows were 'spot on'. I would definitely recommend this company.

Fantastic New Windows Installed

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.
