We had all our windows and doors replaced by AGS, and from start to finish their service was first class From the initial meeting there was no hard sell just lots of useful advice and support; - the fitting was a full weeks work, and any problems that come across was resolved effectively; - the two fitters where excellent and worked very hard and always left everything spotlessly tidy; - the aftersales has been great - any issues have been dealt with in an efficient and effective way.. Goes without saying if you are looking for new windows I would definitely recommend Andy and his team at AGS
