🦺 The Valcourt Group Stands Down for Safety 🦺

Safety isn’t just a week-long focus—it’s a core part of our culture at the Valcourt Group. This month, the Valcourt Group family came together to participate in OSHA’s National Safety Stand-Down to Prevent Falls in Construction, reinforcing our shared commitment to keeping every team member safe on the job.

Across the U.S., we hosted 33 trainings with:
✔️ 1,195 Waterproofing team members
✔️ 584 Window Cleaning team members
💪 1,779 total employees united for safety

👏 A huge thank you to everyone who made this effort impactful—from safety leads and branch teams to the technicians who show up every day to do the job safely.

Let’s keep the momentum going. Every job. Every site. Every day.
