National Contract Glazing was incorporated in May of 2000. Specializing in the design, fabrication and installation of custom aluminum curtain wall, windows, skylights, storefronts and glazing. The two principals, Jean-Guy Tremblay and John Bastedo share a combined personal experience of over 60 years in the Glass and Aluminum industries. Jean-Guy and John have assembled a team of dedicated professionals who are committed to your success.   In 2020, they both decided to retire.

It is with confidence that they chose Jean-Claude Coelho to be their successor. His expertise in construction in general and more specifically Building Science and Building Envelope, his ambitions will take the company to a new level.
