Latest review:
Kory and his team did a very good job of replacing existing bad flat roof with a new GRP covering. A 100% improvement. They were quick and the work was good. Whilst they were there I pointed out some other work that needed doing, including some brick laying, Kory brought in some other members of the team to do the work. Again very good work at a good price. Overall I am very happy and would recommend Kory for any roofing or building work.

Garry and team were very knowledgeable about how the windows should be installed. They managed to retain the Victorian features of the existing windows and were perfectionist when it came to finishing each window. I am very happy with my windows and would highly recommend them.
