We have recently had our front door and windows replaced by Jack of Glass. They were great. The communication was amazing, we knew every step of the way what was happening and they left place spotless. Our new door and windows have completely changed the house. Very happy and would recommend to anyone.

Jack of glass have recently replaced all my windows efficiently and to a high standard. The price was also very reasonable. The customer service was outstanding along with the services they provide. Highly recommended.

Mr Bennett

I had to replace a small double glazed panel in a window. I though it would be difficult to get anybody interested as it was such a small job. However, Jack of Glass did the work. They visited the house to take the measurements, ordered the replacement glass and fitted it all very efficiently and at a reasonable cost. I will use them again.
