The $50 Fall Checklist That Prevents $20,000 in Winter Damage

Skip it and risk: $3,000 - $8,000 (burst pipe + interior water damage)

This is the number one cause of burst pipes we see every winter. Leave a garden hose connected and the water inside the hose bib freezes, expands, and cracks the pipe inside your wall. The worst part? You will not know until spring when you turn the water back on — or until a warm spell mid-winter when the ice melts and water starts pouring into your wall cavity.

Disconnect all hoses. Open the outdoor faucet to let it drain. If you have an interior shutoff valve for outside taps, close it. Two minutes of work. This alone prevents more claims than any other item on this list.

Skip it and risk: $5,000 - $15,000 (ice dams, foundation damage, basement flooding)

Clogged gutters overflow, sending water cascading down your foundation walls. In freezing temps, this creates ice dams at the roofline and ice buildup against your foundation — both of which force water into places it was never meant to go.

Clear them in October, check again in November after the last leaves drop. If you have large trees nearby, gutter guards are worth the investment. A $50 bag of gutter mesh beats a $15,000 foundation repair every time.

Skip it and risk: $10,000 - $20,000+ (flooded basement during snowmelt)

Pour a bucket of water into the pit. Does it kick on? Does it actually pump the water out? If not, fix it before spring melt season — not during it. A failed sump pump during BC snowmelt is a flooded basement. We respond to these calls every single spring and it is always the same story: it worked last year, so they assumed it still worked.

Test it twice a year — fall and early spring. Takes 60 seconds with a five-gallon bucket and tells you everything you need to know.

Skip it and risk: $1,000 - $5,000 (frozen pipes, rodent damage, electrical fire)

Walk your foundation perimeter. Look for gaps around pipes, dryer vents, hose bibs, and any other penetrations. These gaps let cold air in — and more importantly, they let mice in. Mice chew on wires (fire risk) and nest in insulation (damage risk). We have seen house fires start from rodent-chewed wiring more times than you would think.

A can of expanding foam and a tube of exterior caulk from the hardware store handles most gaps. Twenty minutes around the outside of your house. Done.

Skip it and risk: Carbon monoxide exposure, mid-winter failure, frozen pipes from no heat

This is the one item on the list that costs real money, and it is worth every dollar. A tuned furnace runs efficiently and safely. An un-serviced furnace can leak carbon monoxide, fail in the middle of a cold snap, or have a cracked heat exchanger that you cannot see or smell until it is too late.

When your furnace dies at minus 20 and the plumber is booked for three days, your pipes freeze. Now you are dealing with a furnace repair and a burst pipe. Many BC furnace companies offer fall tune-up specials — book in September before the rush.

This is the single most important item on this list.

Know where your main water shutoff valve is and make sure it actually works. Turn it. Right now. If it is seized, if it is buried behind storage, if you cannot find it — fix that before winter.

If a pipe bursts at 2 AM, the difference between a mop-up and a $20,000 flood is whether you can shut off the water in 60 seconds. We have walked into homes where the homeowner could not find the shutoff for 20 minutes while water poured through the ceiling. Every minute the water runs is thousands of dollars in additional damage. If your valve is seized, get a plumber to replace it. That $200 service call is the best insurance you will ever buy.

Skip it and risk: $3,000 - $10,000 (burst pipe in crawlspace or garage)

Any water pipes running through unheated spaces — crawlspace, garage, exterior walls — need pipe insulation. Foam pipe sleeves from the hardware store. They are pre-slit, you just snap them over the pipe. A bag of them costs less than lunch.

Pay special attention to pipes in crawlspaces in the BC Interior. Kamloops, Vernon, Kelowna — these areas see sustained cold snaps that will freeze uninsulated pipes in 24 hours. Ten minutes of work that you only have to do once.

Skip it and risk: $5,000 - $10,000+ (water damage from winter storms)

You do not need to climb up there. Grab binoculars and look for missing or curling shingles, damaged flashing around vents and chimneys, and any visible wear. A winter storm will exploit every weak point on your roof — wind-driven rain and heavy snow loads will find the gaps.

A $200 roof repair in October prevents a $10,000 water damage claim in January. If you see anything concerning, get a roofer out before the busy season. By November, every roofer in BC is booked solid.
