Vancouver Winter Prep: The Complete Home Checklist (Plumbing, Heating, Windows)

What a Vancouver Winter Actually Does to Homes

Vancouver's cold is not Prairie cold, and that is exactly why it damages houses differently. Our core winter - November through February - runs daytime highs of 4 to 8 degrees Celsius with overnight lows just above freezing, delivered as rain, drizzle and saturating humidity. That is two months of water working into every gap a building has, followed by windstorms that test trees and roofs.

Then, once or twice most winters, an arctic outflow funnels cold interior air down the Fraser Valley and the temperature drops to -5 to -15 degrees Celsius with wind - often with clear skies and no protective snow cover to insulate the ground. Homes built for mild dampness suddenly face true freeze conditions: hose bibs split, crawl-space pipes burst, and heating systems that were marginal all season fail at the exact moment they are needed most.

The November 2024 freeze event made this pattern impossible to ignore. A sudden, early cold snap caught Metro Vancouver before homes were winterized, and our emergency line ran wall-to-wall with burst outdoor lines, frozen crawl-space piping, no-heat calls and flooding. The expensive failures shared one trait: they were all preventable tasks on a checklist nobody had gotten to yet. The valley communities - Abbotsford, Mission, Chilliwack - always see the deepest outflow temperatures, but the burst pipes in that event were as common in Vancouver and Burnaby because the unprotected plumbing was identical.

Plumbing: Freeze-Proofing Your Pipes

Frozen plumbing is the number one winter emergency we respond to, and nearly every case traces to the same handful of overlooked tasks. Work this list in order.

Disconnect every outdoor hose

Left attached, a garden hose traps water in the hose bib and the supply pipe behind the wall. When that water freezes, it expands and splits the pipe - often inside the wall cavity where the first sign is a ceiling stain in January, long after the hose was finally removed. Disconnect all hoses, drain them, coil them, and store them in the shed or garage. Then shut off the indoor supply valve feeding each outdoor bib (older Vancouver homes have a shutoff in the basement or a nearby access panel), open the outdoor faucet fully, and let it drain. Frost-free hose bibs help, but they still need the hose off to work as designed.

Know your main shutoff - and prove it

The single most valuable 60 seconds in a flood: knowing where the main water shutoff is and that it actually turns. In most Vancouver-area homes it sits in the basement near the front foundation wall, in a crawl space at the water entry, or beside the water meter. Give it the knowledge test - can every adult in the household close it in the dark? If the valve is seized, corroded or painted over, get it serviced now: trying to learn this on the night of a burst pipe is how small floods become large ones. While you are there, tag it, and clear the boxes stacked in front of it.

Insulate exposed piping

Any water line running through an unheated space - crawl spaces, garages, exterior walls, under decks, along rim joists - is a freeze candidate. Foam pipe insulation sleeves cost roughly $2 per foot at any hardware store and install with a utility knife in an afternoon; choose the sleeve size matching your pipe diameter and slit-fit it around elbows too. Priority zones in our service area: crawl spaces under pre-1980 East Vancouver and Burnaby homes, garage-supply lines in Surrey and Langley townhouses, and pipe runs along uninsulated rim boards everywhere.

Vacation mode, done properly

Travelling over the holidays? Set the thermostat to hold 13 degrees Celsius (55 Fahrenheit) - warm enough to keep interior wall cavities above freezing without paying full heating rates. Then go further: shut the main water valve, open the lowest faucet in the house to drain pressure, and open a high faucet to let air replace water in the lines. A pipe that bursts in an empty, water-shut-off house drips a few gallons; a pipe that bursts with the main open runs for days. For week-plus absences, consider having a neighbour or our service team do a mid-trip walkthrough. Leaving the water on? A smart water-leak sensor under the water heater and near the washing machine ($30 to $60 each) will text you at the first drip.

Hot water recirculation and cold-room checks

If your hot water takes two minutes to arrive at the kitchen tap, your recirculation line (or lack of one) is dumping cooled water through the least-insulated route in the house repeatedly all winter. A demand-controlled recirculation pump retrofits under a sink in a few hours, saves thousands of litres a year, and keeps that pipe run warm - a genuine freeze-prevention bonus for long attic and crawlspace runs. While you are planning it, check that the water heater closet or utility room is not bleeding cold outdoor air through penetrations and that any tankless unit's condensate line is protected and sloped, so it cannot freeze and back up.

For deeper coverage, our plumbing page covers frozen pipe response and prevention in detail, and the burst pipe first-60-minutes guide is the companion read for what to do if prevention loses a round.

Heating: Tune It Before It Breaks

The October furnace tune-up ($149-$229) and why it exists

Heating failures in Vancouver are overwhelmingly January problems created in October. A professional tune-up in October - $149 to $229 for most systems - cleans the burner, verifies the heat exchanger, tests safety limits, replaces the flame sensor if weak, and documents combustion efficiency before the first long run of the season. Book it now because every competent company's calendar fills by mid-October, and November freeze events convert skipped tune-ups into no-heat emergency calls at 11 p.m. - at emergency rates, with parts on backorder during cold snaps.

Filters: the monthly $25 habit

A clogged filter starves the blower, overheats the heat exchanger, and quietly shortens the furnace's life by years. Check the filter monthly through the heating season and replace it every one to three months depending on household dust, pets and filter rating. Write the date on the filter frame with a marker; it is the simplest maintenance log you will ever keep.

CO detectors: test them the same weekend

Carbon monoxide is a winter risk because that is when gas appliances run hardest and houses are sealed tight. Test every CO detector, replace any unit older than its printed expiry (typically 7-10 years), and make sure one sits on every sleeping floor and near the furnace or boiler. If your detectors are past date, replace them - they cost $30 to $60 and they are the only device in the house that can smell an invisible failure.

Heat pump winter mode

Heat pump owners have two pre-winter tasks. First, confirm the outdoor unit has 15 to 30 centimetres of clearance all around and no debris, firewood or plants stacked against it, and that it stands clear of gutter drip lines that can ice the coil. Second, understand your defrost cycle: in damp Vancouver cold, outdoor frost on the coil is normal, and brief steam rising during defrost is the system working correctly, not a fault. Do not switch a heat pump to "emergency heat" during regular cold - it doubles running cost; save it for actual equipment failure, and let cold-climate models do their job to their rated temperature.

A thermostat schedule that matches your life

Programming a weekly schedule instead of holding one temperature saves 5 to 10 percent on heating without touching comfort. A sane Metro Vancouver example:

Going away? Hold 13 degrees Celsius minimum - deep setbacks while travelling are how wall cavities and the pipes inside them reach freezing. The full tune-up checklist and heating service details live on our heating page.

Windows and Doors: Stopping the Drafts

Drafts are comfort killers and heating-bill inflators, and in Vancouver they are mostly a sealing problem, not a window-replacement problem. Sealing the envelope costs dozens of dollars; replacing windows costs thousands (worth it eventually, but rarely an October job).

Find the leaks first: the candle trick

On a windy day, close every window and door and walk the perimeter of each with a lit incense stick or candle held near the frame edges. Where smoke or the flame pulls sideways, air is moving. Test the bottoms of exterior doors, window meeting rails on sliders, and anywhere trim meets framing. Ten minutes of walking finds the winter's worst offenders - typically the front door sweep, the mail slot, the attic hatch, and old sliding-window seals.

Weatherstripping: $15 per door, an afternoon of work

Self-adhesive foam tape, V-strip and door sweeps are hardware-store items costing roughly $15 per door and installable by anyone who can hold scissors. Replace compressed or torn old weatherstripping rather than adding layers on top of it, and sweep-check the door bottom in daylight: light under an exterior door is air moving through the same gap. Door sweeps, threshold adjustment, and foam tape around loose window sashes will recover a surprising share of a drafty room's comfort.

Storm windows, films and curtains

• Interior storm inserts: acrylic or glass panels that magnetize or press into place inside heritage windows - invisible from the street, removable in spring, and they convert a single-pane window to near double-pane performance. Ideal for character homes where replacement is restricted or unwanted.
• Heat-shrink window film: the $20 clear-film kit is a genuine budget solution for basements and bedrooms that will be sealed all winter; applied cleanly it is near-invisible and stops convective loss through the glass.
• Heavy curtains: closed at dusk, open at dawn to capture free solar gain through south glass - the oldest, cheapest window upgrade there is.
• Lock your windows: locking sashes compress their weatherstripping; unlocked sliders and hung windows leak through relaxed seals.

When drafts come from frames that have rotted or glass that fogs between panes, that is a replacement conversation - our windows and doors page covers the options, and the window replacement cost guide has the 2026 numbers.

Gutters and Drainage: Where Winter Damage Starts

The chain of damage is reliably the same every winter: clogged leaves hold meltwater and rain, trapped water freezes, the ice dam backs moisture behind the gutter and under shingles, and the leak enters the wall or soffit. By the time a stain appears on a bedroom ceiling in January, the repair involves roofing, insulation and possibly drywall - versus a $150 to $300 gutter cleaning in October.

Book or perform the cleaning after the last major leaf drop (late October to mid-November for most of Metro Vancouver - the North Shore and any maple-lined street runs later). The job is not just clearing the troughs: flush downspouts with a hose until water runs free, confirm hangers are tight, and make sure downspouts discharge 1.5 to 2 metres from the foundation onto sloped ground or a splash pad. Water pooling at the foundation edge is how wet crawl spaces and hydrostatic seepage happen through the wettest months.

While you are outside: clear the storm drain grate at your curb if leaves are matting over it - a five-minute rake that prevents the classic Vancouver street-flood, which is what pushes water up driveways and into garage door seals. And test any sump pump before the rains: pour a bucket of water into the pit, confirm it cycles, and check the discharge line is not kinked, frozen or dumping right back at the house. Homes in low-lying Richmond, Delta, North Delta and floodplain areas of Abbotsford should treat the sump check as non-negotiable.

Trees and Wind: The West Coast Winter Threat

Vancouver's winter storms arrive from the southwest at 60 to 90 km/h with soaked soil, and that combination takes down trees every season - cedars especially, whose dense canopies act like sails in saturated ground. The result lands on roofs, cars, fences and power lines, and the damage is usually weeks in the making: a cracked limb over the roof that wind finishes.

Walk your property in October and look up. Any dead branch, cracked leader, or limb within falling distance of your roof, car zone or your neighbour's, and any cedar or tall conifer leaning or heaving soil at its base, is a job for a certified arborist. An assessment visit runs roughly $150 to $500 depending on the number of trees, and targeted pruning of problem limbs is far cheaper than the emergency crane removal after a storm. Keep in mind the insurance nuance: a tree that falls because it was clearly dead or neglected can put the damage and even the removal cost dispute on the owner of the tree - documentation of due care matters.

Pre-storm habits worth adopting: clear patio furniture and planters into shelter before forecast windstorms, check that fence panels and gates are latched and braced, know where your electrical panel and exterior disconnect are, and keep the number of a 24/7 service team handy. After a wind event, walk the exterior before the next rain: lifted shingles, shifted flashing and punctured gutter runs leak quietly for weeks otherwise.

The Emergency Kit Every Home Needs

Between windstorms and freeze events, Metro Vancouver loses power somewhere every winter. The prepared household rides it out; the unprepared one discovers that sump pumps, furnaces, fridges and phones all share the same vulnerability. Build the kit once and check it every October:

• Flashlights or headlamps for each person, with spare batteries (headlamps leave hands free)
• Battery bank, charged monthly, plus charging cables for the household's phones
• Battery or crank radio for news during extended outages
• Three days of water - four litres per person per day, refreshed annually
• Three days of no-cook food plus a manual can opener
• First aid kit, and a week of any essential medications
• Battery backup or water-powered backup for sump pumps in flood-prone homes
• Spare furnace filters, and a backup CO detector battery
• Warm blankets, and a plan for the one room you will gather in and heat with the fireplace or safely-rated heater
• Candles and matches as tertiary light only - never for heat
• Cash in small bills, printed copies of key documents, and insurer contact
• Snow brush, ice scraper, and a small snow shovel for the rare but real snow days

Two service notes: know where your gas and water shutoffs are and keep the right wrench within arm's reach of each - a paper label on a pipe beats memory in a panic. And never run generators, barbecues or any fuel-burning equipment indoors or in a garage; every windstorm brings a carbon monoxide emergency somewhere in the region.

Insurance: Coverage and Documentation

November is review season for homeowner policies, because the most common Metro Vancouver winter losses are exactly the ones with the most coverage variation. Pull your policy and check three things. First, burst pipe and sudden water damage - standard policies cover sudden and accidental discharge but not damage from long-term neglect, so the frozen hose bib you were "about to fix" can become a negotiation. Second, sewer and sump backup riders: basic policies frequently exclude backup damage, and the rider is inexpensive relative to one basement event. Third, your deductible and your wind/hail terms, especially in tree-heavy North Shore and Coquitlam neighbourhoods.

Then do the 30-minute documentation pass that turns any future claim from a dispute into a formality: photograph every room, the mechanical room, the water heater, the roof line and gutters, and the exterior walls, and store the set in cloud storage. Keep receipts for major systems, service records, and this winter's prevention work - insulation receipts and tune-up invoices are evidence of due care. Insurers move fastest for documented claims, and adjusters take the photos seriously.

The Week-by-Week Checklist (September to November)

Everything above, sequenced so nothing depends on an emergency. Print this, work top to bottom, and by mid-November your house is ready for whatever the season sends.

Early Warning Signs Not to Ignore

Winter communicates before it destroys. These are the signals that mean a small fix is still available:

• Louder furnace or longer cycles: a system straining against a clogged filter, failing inducer or dirty sensor - tune-up territory today, breakdown territory in January.
• Yellow or orange furnace flame instead of steady blue: incomplete combustion - shut it down and call a gas technician the same day.
• Reduced water pressure at one fixture: a partially frozen supply line warming up by day - insulate that run immediately, before the next clear cold night finishes the job.
• Frost on exposed pipe runs: the pipe is at freezing temperature and asking for insulation now.
• Staining or mustiness at a ceiling edge or soffit: an active gutter or flashing leak already past the first stage.
• Water pooling at the foundation after rain: a downspout or grading problem that will become a crawl-space problem.
• Gurgling or slow drains: a developing blockage that becomes a backup during holiday usage.
• Heat pump icing solid and staying iced: defrost failure - service call before the compressor fights a block of ice.

Anything on this list that you catch this month is an appointment; the same item ignored until the January cold snap becomes an emergency call. Our 24/7 emergency page covers triage when prevention loses - and the average response across our 17 cities is about 45 minutes.
