JMG Windows

“We recently used JMG to do our windows and front door, I have to say how refreshing it was not to have the usual sales flannel and NO pressure to make a decision straight away.  Jamie was really friendly and very knowledgeable, plus our windows look great, the price was also extremely competitive.  Definitely, would recommend them!”
