We hired Unique Construction as the primary electrician for a large commercial project in Lafayette Colorado. After bidding out the project, endless planning, and taking almost 200 thousand dollars, no one ever showed up to do the work. Calls were unanswered, emails were ignored. They completely went off the radar. Due to the loss of time and coordination with other vendors, we have lost millions.
