The underlying logic
Almost every vacant-property failure has damage proportional to how long it runs undetected. A leak, a heating failure, an open door after a break-in, a sump that stopped working — none of these get worse because of what caused them. They get worse because of time.
That makes the visit interval a cap on your worst case. Weekly visits mean nothing runs longer than seven days. Monthly visits mean something could run for thirty.
So the question is not really "how often should it be checked" — it is "what is the longest I am willing to let something run".
What raises the frequency
- Winter, particularly during extreme cold events
- Water left on rather than shut off and drained
- Poly-B plumbing, or supply lines and a hot water tank at end of service life
- A history of basement water or drainage problems
- An older heating system, or one that has not been serviced recently
- A property with no neighbours who would notice anything
- High-value contents or a property that visibly signals affluence
- An insurance condition specifying an interval
- A property under renovation or with trades attending
What allows less
- Water shut off and system fully drained
- Newer construction with modern plumbing and mechanical systems
- Summer rather than winter
- Connected sensors providing temperature and leak data between visits
- Neighbours who are present and engaged
- A property that has been prepared thoroughly rather than simply left
Common cadences
Weekly is the most common arrangement for an Alberta property during the heating season, with owners moving to twice weekly or every 72 hours during deep cold events.
Biweekly is common through summer for a well-prepared property with the water off.
Every 72 hours is typical where the water is on through winter, where an insurance condition requires it, or where the property has known risk factors.
Monthly is generally too infrequent for an Alberta winter unless the water is off and drained and the heating is off, in which case the risk profile is genuinely different.
Related questions
How often should a vacant home be checked?
The honest answer is that it depends on the season, the property and — critically — what your own insurance policy says. There is no universal standard, and anyone who gives you a single number without asking about your policy is guessing.
That said, the practical logic is straightforward. The damage from most vacant-property failures is proportional to how long they run undetected, so the visit interval is effectively a cap on your worst-case outcome. A leak found after three days and the same leak found after three weeks are very different events.
In practice, weekly is the most common cadence for an Alberta property during the heating season, with owners increasing to twice weekly or every 72 hours during extreme cold. Through summer, weekly or biweekly is common. Properties with known risk factors — poly-B plumbing, an aging hot water tank, a history of basement water, or no water shut-off — warrant more frequent visits than a newer, lower-risk property.
The number that actually matters is the one in your policy. Many policies contain a required check interval during extended absences, and some specify who must perform it. Call your insurer or broker and ask directly before you leave.
