I recently made contact due to a blown window, this was put in by myself just under seven years ago. The service given was just fantastic. As soon as I made contact I had an email the next day saying its been ordered and delivery would be the following Monday. Just easy is all I can say, they tried to call but my number had changed over that time. I got an email saying they don't have my updated number. The ladies I dealt with and service I received need for nothing. Exceptional in my opinion.

We bought some aluminium bi-folds from Window Warehouse. The product is excellent and the all their people from sales, admin and delivery were very helpful throughout. An excellent company which we would use again.
