- Gutters: July is the wettest month here (1.7″) — clear them before it, not during.
- Masonry, driveway and sealant: 1 month a year cross freezing both ways on an average day (May). That cycle is what opens cracks — seal them before the season, not after.
- Roof load: October brings the most snow (12″ on an average year). Own the roof rake before then.
- Roof, fence and trees: wind peaks in May at 9.8 mph on average (8.9 mph year-round). Loose shingles, wobbly posts and dead limbs get found for you if you don't find them first.
The small jobs on this list are cheap. The failures they prevent are not:
- $20 faucet covers vs $5,000+ burst pipe
- $40 roof rake vs $8,000+ ice-dam repair
- $150 HVAC tune-up vs $5,000+ replacement
- $150 gutter cleaning vs $3,000+ water damage
Typical U.S. repair ranges — rough estimates, not promises. The risks shown are the ones Yellowknife's climate actually produces.
Spring.
Clean the gutters
Scoop out leaves and grit, then flush with a hose. Watch for water sheeting over the edge — that's a clog telling on itself.
Inspect the roof
Walk the perimeter with binoculars. Look for missing shingles, curled edges, or debris around vents and flashing.
Service the AC
Swap the filter. Hose down the outdoor condenser fins (power off first). Clear a two-foot radius of leaves and weeds.
Reseal exterior wood
Drop water on your deck. If it beads up, you're good. If it soaks in, time to clean, dry, and reseal.
Wake up the yard
Service the mower, reconnect hoses, rake beds. Plant things before the heat sets in.
Test the sump pump
Pour a bucket of water into the pit until the float lifts — the pump should kick on within seconds and send water well away from the house. No sump pit? You're on a slab — skip this one.
Foundation movement check
Look for new cracks, doors that won't latch, or windows that bind. Permafrost thaw shifts foundations every season.
Summer.
Check the irrigation
Run every zone, once. Watch for broken heads, geysers, dry patches, and spray hitting the siding.
Pressure-wash exteriors
Siding, walkways, and the deck, in that order. Use the widest nozzle that still does the job — narrow tips strip paint fast.
Check windows & seals
Run a hand around each frame. Cracked caulk gets a bead of fresh stuff; squished weatherstripping gets replaced.
Walk the pest perimeter
Pencil-width gaps at the foundation, sill plates, and where pipes enter. Seal with copper mesh and expanding foam.
Mow & water smart
Blade on the highest reasonable setting. Water deep and less often, early morning, twice a week.
Vacuum the refrigerator coils
Pull the fridge out (or pop the front grille) and vacuum the dust off the condenser coils. Check the door gasket with a dollar bill while you're there — it should grip.
Refresh bathroom caulk
Check the bead where tub and shower meet tile and floor. Any gap, crack, or black mold line: strip it out and run a fresh bead of silicone.
Fall.
Service the heating
Swap the filter, vacuum around the unit, and test-fire it for twenty minutes. Any odd smells or bangs? Call the pro now, not in January.
Chimney & fireplace check
Before the first fire: damper opens, flue is clear, no nest in the cap. Creosote build-up is a real fire risk.
Winterize outdoor plumbing
Disconnect hoses. Close the interior shut-off for each outdoor spigot, then open the spigot to drain. Insulate exterior-wall pipes.
Clean the gutters (again)
Do this after the last leaves drop. Clear downspouts and direct them away from the foundation.
Stow the outside
Drain the mower fuel or add stabilizer. Cover or bring in the grill. Shake out and store patio cushions.
Flush the water heater
Hook a garden hose to the drain valve and flush until the water runs clear. Test the pressure-relief valve while you're at it — lift the lever, listen for the rush.
Reverse the ceiling fans
Flip the small switch on the fan body so the blades run clockwise on low — it pushes the warm air pooled at the ceiling back down to person height.
Insulate exposed pipes
Foam sleeves on every pipe in unconditioned space — garage, crawlspace, exterior walls.
Wrap the water heater
Insulating blanket on the tank and on the first 6 ft of hot-water pipe. Saves money even on new units.
Attic insulation audit
R-49 or better. Look for compressed batts, daylight at the eaves, and missing baffles at the soffits.
Buy a roof rake
Telescoping aluminum, 16+ ft. Stage it by a door before the first storm.
Test heat tape
Plug it in, feel for warmth along the line, check the GFCI. Replace bulbs and dead sections.
Seal the driveway
Asphalt sealer every 2–3 yr; concrete sealer on a 5-yr cycle. Do it before the first thaw cycle.
Winter.
Watch for ice dams
Big icicles along the eaves mean warm air is escaping into your attic. Real fix: attic insulation. Urgent fix: roof rake.
Mind the indoor humidity
Aim for 30–50%. Below 30, add a humidifier. Above 50, run the bath fan longer and crack a window.
Hunt drafts & drips
Hold a candle near window edges on a breezy day — the flame tattles. Listen for toilets that cycle on their own.
Manage snow load
Rake low-slope and flat roofs after big snows. Keep a path to every exit and to the gas meter.
Check hoses & supply lines
Washing machine hoses, dishwasher line, ice-maker line, and the flex lines under every sink. Bulges, rust, or dampness mean replace — braided stainless, not rubber.
Don't let the house get cold
Heat at 55°F or higher even when away. Open cabinet doors under sinks during deep freezes.
Rinse the garage floor
Hose off the floor whenever the temp gets above freezing. Salt eats concrete and rebar.
Safety.
Test smoke & CO detectors
Smoke alarm on every level and outside every sleeping area. CO alarm near every bedroom. Press the test button.
Fire extinguishers & escape plan
One ABC-rated extinguisher in the kitchen, one near the furnace, one in the garage. Pressure gauge in the green. Walk the escape plan with everyone.
Know the shut-offs
Water main, gas meter, and electrical panel. Everyone in the house should know where each one is and how to operate it in the dark.
Clean the dryer vent
Pull the dryer out, detach the duct, and clear the lint from the full run — machine to the outside flap. Clothes taking two cycles to dry is the warning sign.
Test GFCI outlets
Press TEST on every outlet with the two small buttons — kitchen, baths, garage, outdoors. Power should cut instantly; RESET brings it back.
Home maintenance golden rules
- Water is the enemy. Nine out of ten expensive problems start with water going somewhere it shouldn't.
- Small, often, beats big, rarely. A Saturday every season saves a month of regret later.
- Know what you can't do. Roofs, gas lines, main electrical — call the pro. No prize for bravery here.
- Write it down. Date the filter. Keep receipts. Future-you will thank present-you.

Frequently asked
When should I winterize outdoor faucets in Northwest Territories?
Around Yellowknife the first 32°F night lands about September 16 on average, so have hoses off, spigots drained, and the shut-off closed by September 2. "Average" is the trap — half of all years freeze EARLIER than that date, and a single hard night is enough to split a hose bib you won't notice until spring. The frost-free stretch here runs roughly 113 days, from May 26 to September 16.
How do I prevent frozen pipes in Northwest Territories?
The coldest month around Yellowknife averages a -22°F low — deep enough that an unheated pipe is a question of when, not if. Three habits cover it: insulate every exposed run (garage, crawlspace, exterior walls), never let the house drop below 55F even when you're away, and open the cabinets under sinks on the coldest nights so warm air reaches the pipe inside the wall. The pipe that bursts is almost always the one you couldn't see.
How much snow should a Northwest Territories home be ready for?
Yellowknife averages roughly 60 inches of snow a year — enough that roof load and a clear path to your exits are real planning items, not afterthoughts. Buy the roof rake in October rather than after the first big storm, keep gutters clear going into winter so meltwater has somewhere to go, and walk the property once in autumn for branches that would come down under a heavy wet load.
How often should I clean gutters in Northwest Territories?
Twice a year is the working rule — late spring and late autumn — and Yellowknife's roughly 11 inches of annual precipitation is what makes it non-negotiable. Even in a drier climate it's the concentrated storm runoff that does foundation damage, not the yearly total. Add a pass after any big storm, and check that downspouts discharge at least four feet from the house — most water-in-the-basement calls trace back to that one detail.
What causes ice dams and how do I stop them in Northwest Territories?
Ice dams are an insulation problem disguised as a roof problem. Heat escaping into a cold attic melts snow on the roof; the meltwater refreezes at the cold eaves and backs up under the shingles. The real fix is R-49+ attic insulation with clear soffit baffles. The urgent fix during a storm is a roof rake — buy it in October, not after the first 6-inch snow.
How often should I do home maintenance in Northwest Territories?
A weekend per season handles about 80% of what matters, and around Yellowknife the calendar sets itself: the autumn pass has to finish before the first freeze around September 16, and the spring pass starts once the last freeze passes around May 26. Layer in monthly safety checks (smoke and CO test, a glance at the breaker panel) and one yearly walk of the big shut-offs. The pattern that fails homeowners isn't doing too little — it's doing nothing for two years and then trying to catch up at once.
Can I do this checklist myself, or do I need a pro?
Most of it is DIY — gutters, filters, windows, sealants, irrigation, pest perimeter. Hire a pro for: anything on the roof past a quick eyeball with binoculars, gas-line work, the main electrical panel, and any plumbing repair that involves soldering or splicing into a main. There's no prize for bravery on those — the cost of a mistake is much higher than the cost of the call.
