I recently used professional window cleaning from Cody Building Services in Ottawa and was completely satisfied with the results. Initially, I was skeptical about how well they could clean heavily soiled windows, but the company's technicians exceeded all my expectations. Using state-of-the-art equipment and glass-safe cleaning products, my windows sparkled as if they had just been installed. I was particularly impressed by the attention to detail: every corner and frame were meticulously cleaned, leaving no streaks or smudges. Furthermore, the team worked meticulously, maintaining order, and respecting my privacy. The process took minimal time, and the results were immediately noticeable—the light in the house became brighter, and the building's exterior took on a fresh, well-maintained appearance. I also appreciated the friendly and professional communication from the staff: all my questions and requests were addressed without the slightest problem. Overall, my experience was extremely positive.
