If there's one thing Calgary homeowners learn the hard way, it's this: winter doesn't do its worst damage with snow. It does it with water.
A burst outdoor tap, a sprinkler line that cracked in the first deep freeze, a flooded basement after a chinook melt. These are some of the most common (and most expensive) winter surprises I hear about, and the frustrating part is that almost all of them can be prevented with a little attention in the fall.
The good news? Most of these jobs take less than an hour, and a few of them take less than five minutes. Here's what to tackle before the cold really sets in.
If you have an underground sprinkler system, this is the big one. Any water left sitting in the lines can freeze, expand, and crack pipes and fittings. You won't know anything is wrong until spring, when you turn the system back on and find soggy patches in the lawn and a repair bill waiting for you.
Book your blowout early. Calgary can see a hard freeze well before the snow sticks around, and irrigation companies get very busy once the temperatures start dropping. If you're comfortable doing it yourself, make sure you have the right equipment and know your system's pressure limits. Otherwise, this is a job worth handing to a pro.
It sounds simple, but this one catches a lot of people. Even if you have a frost-free outdoor faucet, leaving a hose attached can trap water inside the valve, where it freezes and splits the pipe. Often that pipe runs inside your wall, which means the leak shows up in your basement, not outside.
Here's what to do:
Unhook all hoses, drain them, and store them somewhere dry.
If your outdoor taps have an interior shut-off valve, close it.
Open the outdoor tap afterward to let any remaining water drain out.
Five minutes of work can save you from a very unpleasant discovery in January.
Once the leaves have mostly fallen, give your eavestroughs a good cleaning. Clogged gutters can't drain properly, and in Calgary, that's a real problem. Our chinooks melt snow on the roof, then the temperature drops again and everything refreezes. Blocked gutters turn that meltwater into ice dams, which can push water back under your shingles or send it spilling right down beside your foundation.
While you're at it, check your downspouts. They should carry water well away from your house, ideally at least a couple of metres. If an extension has come loose or been knocked out of place over the summer, now's the time to fix it.
Take a quick walk around your house and look at how the ground slopes. You want the soil to slope away from your foundation, not toward it. Over time, soil settles, and low spots can form right against the house. Those low spots collect water every time snow melts, and that water has one place to go: toward your basement.
Adding a bit of soil to fill in low areas is an easy fix that can make a big difference come spring.
If your home has a sump pump, give it a quick test before winter. Slowly pour a bucket of water into the sump pit and make sure the pump kicks on and drains it properly. Check that the discharge line outside is clear and pointing away from the house, and that it isn't likely to freeze shut or get buried under snow.
A sump pump that quietly stopped working over the summer is not something you want to find out about during a spring melt.
Pipes that run along exterior walls, in unheated spaces, or under sinks on outside walls are the most vulnerable during a deep cold snap. A few habits go a long way:
Insulate any exposed pipes in unheated areas like a garage or crawl space.
During extreme cold, open cabinet doors under sinks on exterior walls to let warm air in.
If you're travelling this winter, keep your heat on at a reasonable temperature and have someone check on your home.
This one takes thirty seconds and could save you a fortune. Find your home's main water shut-off valve, make sure it turns easily, and make sure everyone in your household knows where it is. If a pipe ever does burst, being able to shut off the water right away can be the difference between a small mess and a major insurance claim.
While you're thinking about it, it's also a great time to review your home insurance policy and make sure you understand what's covered when it comes to water damage.
✅ Blow out the sprinkler system
✅ Disconnect hoses and shut off outdoor taps
✅ Clean eavestroughs and extend downspouts
✅ Fill in low spots around the foundation
✅ Test your sump pump
✅ Insulate vulnerable pipes
✅ Locate your main water shut-off
A Little Effort Now, a Lot of Peace of Mind Later
Your home is likely your biggest investment, and a few hours of fall prep is one of the easiest ways to protect it. Water damage is one of the most common issues that comes up during home inspections, and a well-maintained home is always easier to enjoy (and to sell, when the time comes).
If you have questions about your home, need a trusted trade recommendation, or are curious what your home is worth this fall, I'm always happy to help. Just reach out anytime!
Stay warm, Calgary!
