Winterization

Protecting Your Property Through Ontario Winters

Ontario winters are among the harshest in Canada. A vacant property with no one monitoring the heat or responding to failures is exceptionally vulnerable to catastrophic freeze damage. A single burst pipe can cause $50,000 or more in water damage within hours.

What Winterization Includes

Sentinel's winterization service prepares your property for the full winter season and includes seasonal check-ins to ensure systems remain operational.

Heating System Monitoring

We verify that your heating system is functional and set to maintain a minimum safe temperature. Where heating failures are a risk, we install low-temperature alarms that notify our team immediately.

Pipe and Plumbing Protection

For properties where winter shutdown is preferred, we fully drain all water lines, add antifreeze to trap lines, and shut off the main water supply — eliminating the risk of freeze damage entirely.

Roof and Exterior

Ice damming is one of the most common and damaging winter issues for vacant properties. We inspect and clear vulnerable roof areas, check attic insulation levels, and ensure eavestroughs are clear before freeze-up.
