Our story

Expertise built over the years.

Over the years, Vitrerie Justalex has built a strong reputation for the quality of its work, professionalism and attention to detail. What began as a passion for the trade has grown into a trusted company serving residential and commercial clients with custom glass projects.

2003

The journey begins with Réno-Vitrage enr., a general contractor specializing in glazing. This first company laid the foundation for what would eventually become Justalex.

2009

Réno-Vitrage enr. becomes Justalex Réno-Vitrage inc., a name inspired by Justine and Alexia, the two daughters of the family.

2012

Justalex welcomes its first employee, Sébastien Brunelle. The company moves into its first location and gives its first vehicle the Justalex branding.

2013

François Brunelle joins the team. Justalex continues to grow its team, driven by the same ambition to grow the company.

2014

I am very happy I chose Justalex to replace a half-moon Insulated Glass Unit (8 feet across at its base). In addition, the unit is more than 15 feet above the ground and is very heavy. The installation went exceptionally well, and the result is impeccable! Well done!
