Prepare Your Building for Winter
Winterization isn’t just about turning up the heat. The process involves anticipating where failures might occur, addressing them proactively, and keeping your team informed. At a high level, the steps include:
- Maintain heat and insulation in mechanical, electrical, and riser rooms.
- Drain or protect all exposed sprinkler and water piping.
- Verify fire alarm monitoring and emergency power.
- Inspect roofs and drains before and after freeze events.
- Communicate procedures and responsibilities to all tenants and staff.
- Keep full documentation for insurance and AHJ compliance.
1. Building Envelope & Heating
| Task | Action Steps | Responsible Party |
|---|---|---|
| Inspect and seal exterior openings | Check windows, doors, vents, and roof hatches for leaks. Apply weather stripping or caulking as needed. | Building engineer/maintenance staff |
| Verify insulation and heating in mechanical rooms | Confirm that mechanical rooms, fire riser rooms, and electrical panels are insulated and heated above 40°F (4°C). | Maintenance staff |
| Maintain minimum indoor temperatures | Keep conditioned spaces heated even if unoccupied. Monitor temperature in remote or vacant areas. | Building management / HVAC contractor |
| Test backup or emergency heat | Confirm unit heaters, space heaters, and control systems operate properly on emergency circuits. | HVAC or electrical contractor |
| Roof and drain inspection | Clear roof drains, scuppers, and gutters to prevent standing water and ice buildup. | Maintenance or roofing contractor |
2. Fire Protection & Suppression Systems
Goal: Prevent freezing and ensure operational readiness of fire sprinkler, alarm, and pump systems.
Note that this is especially important in areas like Dallas, where winters are noticeably colder than other population centers like Houston and Austin.
| Task | Action Steps | Responsible Party |
|---|---|---|
| Heat and secure riser rooms | Ensure sprinkler riser rooms are sealed, insulated, and equipped with thermostatic heaters. Keep doors closed and posted. | Maintenance staff |
| Drain low points in dry or pre-action systems | Open auxiliary drains to remove trapped condensation before freezing. | Licensed fire protection contractor |
| Inspect antifreeze systems | Verify antifreeze concentration meets NFPA 25 standards for local low temperatures. | Licensed fire protection contractor |
| Test air compressors and pressure monitoring | Confirm dry system compressors are operational and gauges are accurate. Drain moisture traps. | Licensed fire protection contractor |
| Inspect and test fire pumps | Run weekly churn test; ensure pump rooms have heat and ventilation. | Licensed fire protection contractor |
| Verify alarm communication | Confirm fire alarm signals transmit correctly to the central monitoring station. | Licensed fire alarm technician |
