Installation was 5 wks. after contract signed, by a professional and mostly efficient crew (clean up could have been a bit better). Materials for some finishing work were forgotten and necessitated a return the next day, a bit of an inconvenience for us. We said we did not want a subcontractor to do the job and were assured that this was the contractor's crew. We found out later the crew is a subcontractor who works exclusively for the company, but would have appreciated an explanation beforehand. The job was completed satisfactorily however, so we would recommend with the caveat about subcontractor status. Windows are very high-quality.
