When I called to inquire about our house winterproofing I spoke with Randy and he answered all my questions right away and made my appointment for the following week. Branden and Tiffany arrived on the scheduled date and explained everything they were going to do. They started the work right away and when something came up that they were unsure of what we thought they asked us our opinion how we would like it done, very professional. When we asked any questions they were very knowledgeable with the answer. They were always very courteous and did their work with pride. We were very happy with the end results and would highly recommend Great North Insulation Company to do the job right.
