Frozen & burst pipes
Frozen & Burst Pipe Damage
The signature loss of this region. A supply line lets go in a building nobody is standing in, and the discovery date is the number that decides everything.
Shut the water off at the main, then read the rest of this. If you cannot find the main, that is the first thing to ask us on the phone, and it takes about a minute.
Why this is the loss that defines the trade here
A burst supply line runs at mains pressure and does not stop. In an occupied house somebody hears it, and the damage is measured in hours. Across a great deal of this market that is not the situation: The Blue Mountains, Craigleith and the escarpment above them are full of buildings that are visited rather than lived in, and Wasaga Beach empties almost entirely for the winter. A line that fails on a Tuesday in January in an empty chalet is found when somebody drives up for the weekend, or in March.
That gap is the whole cost difference. Three hours of water is a drying job. Three weeks of water is a demolition, an insulation replacement, a mould remediation and frequently a floor structure question — and it is the same failed fitting either way.
| Found after | What is typically wet | What the work becomes |
|---|---|---|
| Under 6 hours | Finishes and the room it happened in | Extraction and drying |
| 1–3 days | Cavities, insulation, the floor below | Partial removal, then drying |
| 1–3 weeks | Structure, and mould has started | Removal, remediation, rebuild |
| Over a month | Everything below the failure, plus contents | A rebuild with a drying phase in it |
Where the pipes actually freeze
Rarely in the middle of a heated room. The failures we are called to cluster in the same handful of places: a line run in an outside wall, a crawl space with a vent somebody never closed, an unheated garage that holds the laundry, a cottage kitchen on a slab addition, and — most often on the escarpment — a service that runs through an unconditioned space between two heated ones.
The failure is usually at the thaw, not at the freeze
Ice forming in a pipe does not always split it. What splits it is the pressure trapped between the ice plug and a closed fixture, and what releases the water is the thaw. So the flood does not arrive on the coldest night. It arrives two days later, on the mild afternoon, which is why the first warm spell after a hard cold snap is the busiest run of calls in this trade all year and why a property checked during the cold snap and not after it has not really been checked.
Frozen pipe damage in a seasonal Blue Mountains property
A property that is shut down properly — drained, valves open, low heat maintained and monitored — very rarely produces this call. A property that is merely left at 12°C with the water on produces it repeatedly. The difference costs almost nothing in October and a great deal in February, and it is the single most useful piece of prevention in our whole service area.
Freeze-thaw counts and what they mean for a supply line
Environment Canada normals at the nearest reporting station put the Collingwood area at about 92 days a year that cross the freezing point and come back. Each one of those is a cycle for whatever is sitting in an unheated space, and the coast along Nottawasaga Bay and the escarpment behind it do not experience them on the same days. That is why a monitored low-temperature alarm is worth more here than a thermostat setting.
FAQ
Frozen & burst pipes — common questions
The pipe burst weeks ago and nobody was here. Is it still a drying job?
Usually only partly. After that long the assumption has to be that materials in contact with the water have failed rather than merely got wet, and that mould growth is established behind finishes. The honest sequence is an inspection that establishes the boundary of the affected area first, because the answer decides whether this is drying with some removal or a rebuild with a drying phase inside it.
Will insurance cover a burst pipe in a property I do not live in?
It depends on the policy wording, and seasonal and unoccupied properties are exactly where wordings differ most. Many require the water to be shut off and drained, or heat maintained and the building checked at a stated interval, for freeze damage to be covered. Read that clause before you need it. We will tell you plainly what we can see about the cause, but the coverage question belongs to your broker and your adjuster.
Do you fix the pipe?
No. The plumbing repair is a licensed plumber's work and the rebuild is a carpenter's, and we would rather say that than pretend a single call covers all three. What we do is stabilise, establish what is wet, remove what has to come out and dry the rest to a measured standard, so the trades that follow are working on a dry building.
Talk to a Collingwood water damage restoration company
Tell us where the water is, where you think it came from, and when you first saw it. Those three answers decide almost everything — whether this is an afternoon of drying or a scope with removal in it, whether it is likely to be an insurable event, and whether the honest advice is to stop reading and shut the water off first.
