I have 4 of my window glass replaced with new insulated glass units. I'm very satisfied with the service provided by Chris of the Glass Guru of North Surrey. He's very courteous in answering my questions. He worked with care and diligence. I can see that he's had a lot of experience installing IGUs as he worked promptly and accurately. Bottom line, I'm very happy with my windows. I definitely will trust him again for my other home projects in the future.
