I was very impressed with the professionalism and level of service Green Shield performed on my home. The installer came right at 8am as we requested and worked diligently for the entire day until the front of my home was complete. They set down drop sheets, cleaned up after themselves and wiped down all the windows. After they were finished my father (retired carpenter) inspected their work and he concluded that the job was "professionally done", which is great feedback knowing his standards. I have been recommending Green Shield since my installation in Sept 2010, and I hope to do the back of my house this year.
