Safety checklist — Doors and windows
Installation of doors, windows and hardware. Based on Québec's Construction Safety Code (CSTC) and CNESST standards.
Before work
10 items- ✓
PPE worn: cut-resistant gloves, safety glasses, safety shoes
- ✓
Openings verified — dimensions conforming to plans
- ✓
Installation materials available (foam, screws, shims, membrane)
- ✓
Fall protection in place if installing at height
- ✓
Glazing handled with suction cups — cut-resistant gloves
ℹ️ Good practice. The CSTC does not write “cut-resistant gloves mandatory” for glazing.
- ✓
Frame plumb and level verified before final fastening
- ✓
Adequate shimming to hold frame during screwing
- ✓
Expanding foam applied without excess — don't distort frame
- ✓
Waterproofing membrane installed around frame (flashing)
- ✓
Glazing set on setting blocks — not resting on frame alone
After work
4 items- ✓
Opening and closing tested — hardware functional
- ✓
Exterior caulking applied — air and water seal

Temporary protection applied on new glazing

Packaging and trimmings recovered — area cleaned

Risks and prevention — Doors and windows
Door and window installation exposes workers to glass cuts, musculoskeletal strain from heavy frame lifting, and falls during upper-storey installation. CSTC 3.8.3 / 2.9 govern openings and falls. Protect voids while work is underway.
Large windows often require vacuum lifting equipment or hoists. Coordination between interior and exterior crews is essential to prevent glass drops and crushing.
