Reviews
What customers say
Two customers praised the service on small residential and custom-glass projects, and one specifically described the communication as kind and clear. A customer reported two mismeasured windows, a later delivery of the wrong window type, more than 90 days before the correct windows were installed, and dismissive responses. Other reported problems included streaking in installed glass, unanswered requests to order replacement windows and unavailable digital payments.
