We don't get the extreme winters that other parts of Canada deal with, but homeowners in Victoria, Langford, Saanich, and the surrounding areas know that cold snaps happen — and when they do, exposed or unprotected plumbing is the first thing to suffer. A frozen pipe can crack or burst in a matter of hours, turning a mild weather event into a costly emergency.
The good news is that winterizing your plumbing is straightforward. Most of it you can do yourself in an afternoon. This checklist covers everything a Victoria homeowner needs to know to get through the season without a surprise call to an emergency plumber.
If anything on this list feels unfamiliar or you would rather have a professional handle it, our team is happy to help. Call us at (778) 265-6446.
Know Where Your Main Water Shutoff Is
This is the single most important thing you can do — not just for winter, but year-round. If a pipe freezes and bursts, the first thing you need to do is stop the flow of water. Every second counts when water is pouring into your home.
In most Victoria homes, the main shutoff valve is in the basement or crawlspace near the front of the house, close to where the water main enters the building. It may be a gate valve (round handle, turns multiple times) or a ball valve (lever handle, quarter turn). Ball valves are more reliable — if yours is an older gate valve that is stiff or hard to turn, consider having it replaced before winter.
Find it now, test it, and make sure everyone in the household knows where it is. Tag it with a label if it's in a dark or cluttered area. In an emergency, you do not want to be searching for it with a flashlight while water is running.
Insulate Exposed Pipes
Any pipe that runs through an unheated space is vulnerable — and in Victoria homes, that typically means crawlspaces, garages, and exterior walls. These are the pipes most likely to freeze when overnight temperatures dip below zero.
Pipe insulation sleeves (the foam tubes you can pick up at any hardware store) are inexpensive and easy to install. Slip them over exposed hot and cold water lines and secure the seams with tape. Pay particular attention to:
- Pipes running through the crawlspace, especially near vents or openings
- Any supply lines in an unheated garage
- Pipes along exterior walls, particularly on the north side of the home
- The hot and cold lines leading to outdoor hose bibs
For areas that are especially cold or hard to heat, self-regulating heat trace cable is an option. It wraps along the pipe and provides gentle warmth to prevent freezing. A licensed plumber can advise on whether heat trace makes sense for your home.
Outdoor Taps and Irrigation
Outdoor hose bibs are the most common casualty of Victoria's cold snaps. Water left sitting in an outdoor tap or a connected garden hose will freeze, expand, and crack the fixture — or worse, the pipe behind it inside the wall.
Before the first frost:
- Disconnect all garden hoses from outdoor taps and drain them
- If your outdoor tap has an interior shutoff valve, close it and then open the outdoor tap to let any remaining water drain out
- Drain irrigation systems — blow out the lines with compressed air if your system has a blowout port, or open the drain valves and let gravity clear the water
- Insulate outdoor taps with foam hose bib covers — they cost a few dollars and take seconds to install
If you have frost-free hose bibs installed, they are designed to drain automatically — but only if the hose is disconnected. Leaving a hose attached defeats the purpose and traps water in the line.
Protect Pipes in Unheated Spaces
Crawlspaces and garages are the areas most likely to cause problems because they sit outside the heated envelope of your home. A few steps to reduce the risk:
- Seal crawlspace vents during cold weather or install vent covers that can be opened in warmer months
- Add pipe sleeves or heat trace to any water lines running through the crawlspace
- Make sure the crawlspace access door fits snugly and is not letting cold air pour in
- On cold nights, open kitchen and bathroom cabinet doors on exterior walls to let warm air circulate around the pipes behind them
If you have plumbing that runs through a garage, keep the garage door closed as much as possible during cold stretches. Even a partially open garage door lets enough cold air in to freeze exposed pipe overnight.
Leaving for More Than a Few Days?
Heading south for the holidays or leaving your Victoria home for a week or more during the winter months? A few precautions will protect you from coming home to a disaster:
- Keep the thermostat at 16 °C (60 °F) minimum — never turn the heat off entirely while you are away in winter
- Shut off the main water supply and open a couple of taps to relieve pressure in the lines
- Ask a neighbour, friend, or property manager to check on the home every two to three days
- If you have a smart thermostat or leak sensor, set up alerts so you are notified immediately if the temperature drops or water is detected
Many home insurance policies in BC require that the home be checked regularly during extended absences in winter — often every 48 to 72 hours. Failing to do so can void your water damage coverage. Check your policy before you leave.
Signs a Pipe Has Frozen — and What to Do
If the temperature has dropped and you notice any of the following, you likely have a frozen pipe:
- Reduced water flow or a tap that barely trickles when you turn it on
- No water at all from a specific tap or fixture
- Visible frost on the outside of an exposed pipe
- A pipe that feels ice-cold to the touch or looks swollen
If you suspect a pipe is frozen but has not yet burst, you can attempt to thaw it gently using a hair dryer, warm towels, or a space heater placed nearby. Never use an open flame, propane torch, or heat gun directly on a pipe — this can damage the pipe, melt fittings, and create a serious fire hazard.
Open the tap that the frozen pipe feeds so that water can flow as the ice melts and pressure is relieved. Work from the tap back toward the frozen section.
If you cannot locate the frozen section, if the pipe has already burst, or if you are not comfortable working on it yourself — shut off the main water supply and call us immediately. Our team provides emergency plumbing repairs across Greater Victoria.
"A couple of winters ago temperatures dropped well below zero for three nights running. Burst pipes in crawlspaces, flooded garages, cracked outdoor taps — the calls came in across Victoria, Langford, and Saanich.
The frustrating part is that nearly every one of those calls was preventable. A few dollars in pipe insulation, a disconnected garden hose, a thermostat left at a reasonable setting — that's all it would have taken. I put this checklist together because I would rather help homeowners avoid the problem than fix it after the damage is done."
