Vancouver homes are not built for deep cold, so it only takes a few days below freezing to find every uninsulated crawlspace run and every hose left on a tap.
A burst pipe is a race against water volume. Everything else — the repair, the insurance, the drying — is downstream of how fast the supply gets shut off. If you take one thing from this page, make it this: find your main shut-off valve now and label it.
Once the water is off we cut back to sound pipe, make a permanent repair rather than a clamp, pressure-test it, and then look at why that particular run froze. A pipe that froze once in an unheated crawlspace will freeze again in the next cold snap unless something changes.
The single highest-value five minutes you can spend. A hose left attached traps water against the bib, and the resulting split is usually inside the wall.
Most Vancouver crawlspaces have at least one length of uninsulated supply pipe. Foam sleeve is cheap and it is the difference between a normal winter and an emergency call.
Label it. Show everyone in the house. In a real burst, the time spent hunting for the valve is the most expensive part of the whole event.
Most calls turn up something else worth looking at. Here is what else we handle.
We answer 24/7. Every minute the water is off is damage that does not happen.
