Clera Windows + Doors

I researched 5 window companies to replace my current ones, and returned to the same company that installed some doors and windows 10 years ago. Ron, the salesperson was informative, helpful and flexible. However, it is the installer Diego who was a true craftsman and values excellent work. We installed retrofit windows to preserve the interior moulding of the house and the capping he spent (5 hrs on the bay windows) ensuring the front looked well with the rest of the house was impressive. Since we live in Toronto, the competition for work is high, however, the quality and follow up is varied. Clera windows with Diego working for them for 17 years suggests something about how a company treats its employees. This is my signpost when I hire contractors to work on the house; how long are employees with the company.
