a little care, all year long
Minnesota Seasonal
Home Maintenance Guide
Minnesota weather puts a house through everything — deep freezes, spring meltwater, summer storms, and back again. This season-by-season checklist covers the jobs that matter most here, so small tasks never turn into big repairs.
Spring
March · April · May You are hereSpring in Minnesota is really about one thing: water. Snowmelt and spring rains test your sump pump, gutters, and grading all at once — while you check for whatever winter left behind.
Outside
- Clean gutters and downspouts once the thaw is done, and confirm downspout extensions carry water 4–6 feet from the foundation.
- Inspect the roof for shingles lifted or damaged by ice dams and winter winds.
- Check grading — soil should slope away from the house so meltwater drains off, not in.
- Turn outdoor faucets back on slowly and check inside for any pipes that cracked over winter.
- Start up the sprinkler system after the last hard freeze (usually late April–May) and check heads for winter damage.
- Rake out the lawn, then apply crabgrass pre-emergent when soil warms to about 50–55°F — the old Minnesota cue is when the lilacs bloom.
- Wash windows and repair screens before bug season arrives in earnest.
- Inspect the deck and driveway for frost heave and winter cracking; plan sealing and repairs.
Inside & Systems
- Test the sump pump before the big melt — pour a bucket of water in the pit and confirm it kicks on. A battery backup is cheap insurance.
- Walk the basement after the thaw and after heavy rains, checking corners and walls for moisture.
- Service the air conditioner in spring so you're not in line behind everyone else on the first 90° day.
- Check the attic for leaks or staining left by ice dams.
- Flush a few gallons from the water heater to clear sediment, or schedule it with your plumber.
- Clean the dryer vent line all the way to the exterior — lint buildup is a fire risk.
- Test smoke and carbon monoxide alarms and swap in fresh batteries.
- If you have a well, test the water yearly — spring is a good anchor date. Septic systems get pumped every 3–5 years.
Summer
June · July · August You are hereSummer is the season for exterior projects and storm watch. Humidity management inside, hail and heavy rain outside — and the best working weather of the year for anything that needs paint, stain, or sealant.
Outside
- After any hail or severe storm, inspect the roof (from the ground with binoculars is fine) and photograph any damage promptly for insurance.
- Touch up exterior paint and caulk — summer is the only reliable window for both in Minnesota.
- Clean and reseal the deck every couple of years; check boards and railings for rot.
- Trim trees and shrubs back from the siding, roof, and AC unit — keep a few feet of air space around the condenser.
- Water the lawn deeply and less often to grow deep roots, and mulch beds to hold moisture through hot spells.
- Check window wells are clear of leaves and debris so storm water drains instead of pooling against basement windows.
- Seal asphalt driveway cracks before freeze-thaw season turns them into craters.
- Mid-summer gutter check — summer storms clog them fast with seeds and storm debris.
Inside & Systems
- Run a basement dehumidifier and keep indoor humidity around 30–50% to prevent musty odors and mold in humid months.
- Change the AC filter monthly during heavy cooling use.
- Watch for pests — carpenter ants, wasp nests under eaves, and bats in the attic all peak in summer. Seal gaps you find.
- Test the garage door auto-reverse and lubricate hinges and rollers.
- Check the attic on a hot day — it should be warm but ventilated; blocked soffit vents make the whole house work harder.
- Inspect washing machine and dishwasher hoses for bulges or cracks; braided steel replacements are inexpensive.
- Clean the range hood filter and give the garbage disposal a rinse of ice and citrus.
- Review your sump pump again mid-summer — thunderstorms drop a lot of water fast.
Fall
September · October · November You are hereThis is the most important season on the Minnesota maintenance calendar. Nearly every expensive winter problem — frozen pipes, ice dams, a dead furnace in January — is prevented by work done in September, October, and November.
Outside
- Blow out the sprinkler system before the first hard freeze — October is the standard window, and a cracked line from frozen water is an expensive spring surprise.
- Disconnect every garden hose, shut off the interior valve to each outdoor faucet, and open the faucet to drain. A hose left on is the #1 cause of burst pipes here.
- Clean gutters after the leaves drop (late October–November) so melting snow has somewhere to go.
- Inspect the roof and flashing before snow covers it for five months.
- Caulk windows and renew weatherstripping — drafts you feel in October are heating dollars in January.
- Check attic insulation and ventilation — this is your main defense against ice dams. Warm air leaking into the attic melts roof snow unevenly.
- Apply fall "winterizer" fertilizer and give the lawn a final mow slightly shorter than summer height.
- Drain and store rain barrels, cover or bring in patio furniture, and service the snowblower before you need it — not during the first storm.
Inside & Systems
- Schedule the annual furnace tune-up in September or October — HVAC companies book out fast once the first cold snap hits.
- Replace the furnace filter and stock spares for winter's monthly changes.
- Test carbon monoxide alarms before heating season starts; CO risk peaks when the furnace runs daily.
- Have the chimney swept if you burn wood, before the first fire of the season.
- Test the sump pump one more time before the ground freezes.
- Seal foundation cracks inside and out — freeze-thaw widens them, and mice need only a dime-sized gap.
- Reverse ceiling fans to a low clockwise setting to push warm air back down.
- Stock up: ice melt, a roof rake, furnace filters, and flashlight batteries — all easier to find in October than in a January blizzard.
Winter
December · January · February You are hereWinter maintenance is mostly vigilance: keep the heat running safely, keep water moving where it should, and keep snow and ice from quietly damaging the roof and foundation.
Outside
- Watch for ice dams — thick ice ridges at the roof edge. Use a roof rake from the ground to pull snow off the first 3–4 feet of roof after heavy storms.
- Keep furnace and water-heater exhaust vents clear of snow — high-efficiency units vent through PVC pipes near ground level, and a blocked vent can push carbon monoxide indoors.
- Clear snow away from the gas meter, dryer vent, and basement windows.
- Shovel snow away from the foundation rather than piling it against the house, so spring melt drains away.
- Clear walks promptly — most Minnesota cities require sidewalks cleared within about 24 hours of a snowfall.
- Knock icicles down carefully where they hang over walkways and entries.
- Check the roof after major storms for uneven snow loads, especially on additions and low-slope sections.
Inside & Systems
- Change the furnace filter monthly while the furnace runs around the clock — a clogged filter is the most common cause of a no-heat call.
- During deep cold snaps (below zero), open cabinet doors under sinks on exterior walls and let faucets drip slightly to protect pipes.
- Know where your main water shutoff is — and make sure everyone in the house knows — before you ever need it in a hurry.
- Run the humidifier and aim for 30–40% indoor humidity; much higher causes frost and condensation on windows, much lower dries out wood floors and trim.
- Peek into the attic mid-winter: heavy frost on the underside of the roof deck signals warm air leaking up from the house — a spring project note.
- Test smoke and CO alarms monthly while the house is closed up tight.
- Test your home for radon. Winter's closed-house conditions give the most accurate reading, and Minnesota has some of the highest radon levels in the country — test every few years, especially with a finished basement.
- Book spring contractors early — roofers, HVAC techs, and landscapers fill their Twin Cities schedules by March.
the steady habits
Every Month, All Year
A short standing routine that keeps the seasonal jobs small.
Monthly
- Change or check the HVAC filter every 1–3 months depending on the filter type, pets, and how hard the system is running.
- Test smoke and carbon monoxide alarms with the test button.
- Run water in rarely used drains (guest bath, floor drains) to keep traps full and sewer gas out — especially important in dry winter air.
- Glance under every sink for drips or moisture before a slow leak becomes a cabinet replacement.
- Check your water bill — a sudden unexplained jump often means a running toilet or hidden leak.
Once or Twice a Year
- Professional furnace and AC service — one visit each, in fall and spring.
- Clean the dryer vent line end to end, spring and fall.
- Inspect the water heater for rust or weeping at the base; most last 8–12 years, so knowing its age saves a surprise.
- Review the roof, gutters, and foundation on a slow walk around the house twice a year — most big repairs are visible small problems first.
- If you're on a well: annual water test. If you're on septic: pumping every 3–5 years.
