Conservatory & Doors

"Very impressed with Global Windows. I contacted them regarding my 16 year old conservatory. After 16 years one of the doors has dropped slightly, I phoned for advice on how to adjust the door, the response was, don’t worry we will come out and adjust it for you. Not many firms will do that for something 6 years out of warranty."
