General notes · Fit guide

Which one fits your project?

When ACG is the fit

  • Your project is in Florida or Tennessee — ACG works the Southeast, while Giroux Glass operates in California, Nevada, and Arizona.
  • You need Florida hurricane-zone expertise: HVHZ Miami-Dade NOA compliance and Florida Product Approval glazing ACG installs as routine work.
  • You want a single owner-level decision-maker reachable directly — Connor or Rielly on every change order and schedule call.
  • You value a Woman-owned · Rielly Walsh, CEO and 51% majority owner, Procore-native sub with 48-hour bids on documented scopes.

When Giroux Glass is the fit

  • Your project is in California, Nevada, or Arizona, where Giroux Glass has decades of regional relationships and crews.
  • You want an established, ENR-ranked specialty contractor with a nearly 80-year track record and an employee-owned (ESOP) culture.
  • Your scope leans toward high-end West Coast retail, architectural metals, or luxury residential glazing in Giroux's home markets.

Both companies build good buildings. They are built for different jobs — and different coasts.
