Home Maintenance Calendar: What to Do Each Month

Home maintenance rarely fails because owners do not care. It fails because everything seems optional until something breaks. A calendar solves that by converting a vague obligation into a short list attached to a month.

This calendar assumes a typical single-family home in a four-season climate. Adjust the seasonal items if you live somewhere warm year-round, and skip exterior items if your association handles them. Most months take under an hour.

How to Use This Calendar

• Pick a fixed day — the first Saturday of each month works well — and put it on your calendar as a recurring event.
• Do the monthly core first, then the seasonal items for that month.
• Write down what you find, even when nothing needs action. Trends matter more than single observations.
• Schedule contractors early. Furnace technicians in October and roofers after a storm are booked out for weeks.
• Do not climb what you are not comfortable climbing. Binoculars from the ground are an acceptable roof inspection.

The Monthly Core: Four Recurring Tasks

These four take fifteen minutes combined and prevent a disproportionate share of common problems.

1. Check the HVAC filter. Hold it to a light. If you cannot see light through it, replace it. A restricted filter raises energy use and strains the blower.
2. Test smoke and carbon monoxide detectors. Press the test button on each unit.
3. Walk the perimeter and the basement or crawlspace. Look for water stains, damp spots, musty smells, and new cracks.
4. Run water in unused fixtures. Guest bathrooms and floor drains have traps that dry out and let sewer gas in.

January

Deep winter. Focus on heating performance, ice, and interior humidity.

• Check for ice dams at roof edges and icicles along gutters; both signal heat loss into the attic.
• Inspect the attic for frost or condensation on the underside of the roof deck, which indicates a ventilation problem.
• Monitor indoor humidity. Roughly 30–40% in winter limits condensation on windows without drying out the house.
• Keep cabinet doors open under sinks on exterior walls during hard freezes, and know where your main shut-off is.
• Test the sump pump by pouring water into the pit; thaw cycles arrive fast.
• Vacuum refrigerator condenser coils and clean the range hood filter.
• Review your homeowners policy renewal and confirm coverage limits still match rebuild costs.

February

The quietest month is a good time for indoor systems and planning.

• Inspect plumbing supply lines to washing machines, dishwashers, and toilets. Replace rubber hoses with braided stainless lines if they are more than five years old.
• Check under every sink for slow drips and corrosion at shut-off valves.
• Test GFCI and AFCI outlets using the test and reset buttons.
• Clean the dryer vent duct, not just the lint trap. Restricted ducts are both an efficiency and a fire concern.
• Inspect the water heater for rust at fittings and moisture on the floor beneath the tank.
• Get quotes now for spring projects; contractor availability is best before the season starts.
• Check garage door balance and the auto-reverse safety feature.

March

The thaw reveals winter damage. This is the most productive inspection month of the year.

• Inspect the roof from the ground for missing, lifted, or curling shingles and damaged flashing.
• Clean gutters and downspouts after the last freeze; confirm downspouts discharge at least several feet from the foundation.
• Walk the foundation looking for new cracks, spalling, or soil that has settled toward the house.
• Check caulking and weather seals around windows and doors; winter is hard on both.
• Inspect the driveway and walkways for freeze-thaw cracking and seal where needed.
• Reconnect and pressure-test exterior hose bibs after the freeze risk passes; watch for leaks inside the wall.
• Service the lawn mower and small engines before the first mow.

April

Prepare cooling equipment before you need it and address water management.

• Schedule an air conditioning tune-up. April technicians are available; July technicians are not.
• Clear leaves and debris from the outdoor condenser unit and maintain roughly two feet of clearance around it.
• Pour water down the condensate drain line and confirm it flows; clogged lines cause ceiling and wall damage.
• Test the sprinkler or irrigation system, checking for broken heads and misdirected spray against siding.
• Inspect the deck or patio for loose boards, popped nails, and rot at ledger connections.
• Check window and door screens and repair tears before insect season.
• Look for early pest activity: mud tubes at the foundation, carpenter ant frass, or wasp nests under eaves.

May

Exterior surfaces and drainage.

• Wash siding and check for damage, gaps, and failed paint.
• Touch up exterior paint and caulk; small gaps admit water and insects.
• Trim vegetation back from siding, roofline, and the air conditioner.
• Confirm grading slopes away from the foundation; add soil where settling has created a low spot.
• Inspect fences and gates for rot at ground contact.
• Clean and inspect the grill, and check the propane connection for leaks with soapy water.
• Check attic ventilation and confirm soffit vents are not blocked by insulation.

June

Cooling season begins. Verify efficiency and comfort.

• Confirm the air conditioning is cooling adequately; a large gap between set and actual temperature during moderate weather signals a problem.
• Inspect ductwork in unconditioned spaces for disconnected sections and missing insulation.
• Check ceiling fan direction — counterclockwise in summer pushes air down.
• Clean bathroom exhaust fan covers and confirm they vent outdoors rather than into the attic.
• Inspect the washing machine drain hose and the dishwasher supply line.
• Look for standing water anywhere on the property; it invites mosquitoes and foundation issues.
• Review your emergency plan and supplies if you live in a storm-prone region.

July

Peak heat. Keep tasks short and indoors where possible.

• Flush the water heater to remove sediment, following the manufacturer's instructions, and test the temperature and pressure relief valve if you are comfortable doing so.
• Inspect and clean the garbage disposal, dishwasher filter, and refrigerator water filter.
• Check the attic on a hot day; excessive heat indicates ventilation problems that shorten shingle life.
• Inspect window seals for fogging between panes, which indicates a failed insulated unit.
• Verify that outdoor outlets and lighting are working and weather-sealed.
• Monitor for pests entering to escape heat; seal gaps around pipes and utility penetrations.

August

Begin the transition toward fall and get ahead of scheduling.

• Schedule a heating system tune-up for September or October now, before the rush.
• Inspect and clean gutters if summer storms have left debris.
• Check chimney and fireplace condition, and book a sweep if you burn wood.
• Inspect insulation levels in the attic; late summer is a comfortable time compared to what comes next.
• Test the sump pump and backup battery if you have one.
• Wash windows and inspect frames and sills for rot.
• Review energy bills against last year to spot developing efficiency problems.

September

Weatherproofing month. Every hour here pays back in winter comfort and utility cost.

• Replace worn weatherstripping on doors and add door sweeps where you can see daylight.
• Caulk exterior gaps around windows, trim, and utility penetrations before temperatures drop.
• Have the furnace or boiler serviced, and replace the filter.
• Test the heating system early on a cool morning so problems surface while service is available.
• Check the roof and flashing again before leaves fall.
• Inspect the driveway and seal cracks before freeze-thaw widens them.
• Seal exterior entry points against rodents, which begin seeking shelter this month.

October

Winterization. The deadline-driven month.

• Clean gutters after leaf drop — the single most important fall task in most climates.
• Shut off and drain exterior hose bibs, disconnect hoses, and install faucet covers.
• Blow out or drain irrigation lines.
• Reverse ceiling fans to clockwise at low speed.
• Check attic insulation depth and add where it is thin or displaced.
• Inspect and test the chimney damper, and confirm the cap and screen are intact.
• Store or cover outdoor furniture and drain fuel from seasonal equipment.
• Stock winter supplies: ice melt, shovels, and spare furnace filters.

November

Final checks before deep cold.

• Verify the heating system is running efficiently and that all vents and radiators are unobstructed.
• Insulate exposed pipes in unheated spaces such as crawlspaces, garages, and attics.
• Test all smoke and carbon monoxide detectors again; heating season raises CO risk.
• Check the attic for signs of rodent entry now that outdoor food sources are gone.
• Confirm exterior lighting works, since evenings are dark.
• Clean the range hood and oven ahead of heavy cooking season.
• Review your annual maintenance log and note what you deferred.

December

Light month. Focus on safety and planning.

• Inspect extension cords and holiday lighting for damage; do not overload circuits.
• Check fire extinguisher gauges and confirm each is accessible.
• Watch for condensation on windows and adjust humidity if moisture is collecting.
• Clear snow away from furnace intake and exhaust vents on high-efficiency systems — blocked vents can shut the system down or create a CO hazard.
• Keep the path to your water shut-off clear.
• Plan and budget next year's projects using what you logged this year.

Adjusting for Your Climate

What Annual Maintenance Costs

A widely used planning figure is about 1% of the home's value each year, though older homes and larger lots often run higher and newer homes lower in the early years. That budget covers both routine service and the occasional larger repair.

For a fuller treatment of how to size your reserve, see how much to budget for home maintenance each year.

Keeping a Maintenance Log

A log is what turns this calendar from a chore list into an asset. Record the date, the task, what you observed, and any cost. A simple note on your phone or a spreadsheet is enough. The benefits compound:

• You learn your home's actual filter interval, gutter load, and system behavior instead of guessing.
• Documented servicing supports manufacturer warranty claims.
• A record of maintenance is persuasive at resale and helpful for appraisals.
• Patterns become visible — a basement that is damp only after heavy rain points to drainage, not plumbing.

Conclusion and Next Step

Maintenance is not about doing everything. It is about doing the right small thing at the right time so the large thing never happens. If you adopt only part of this calendar, keep the monthly core plus two gutter cleanings and two HVAC services a year — those five habits cover the most common sources of expensive damage.

Next, put a number to it. Run your home through the Full Home Cost Calculator with maintenance included, and if you have recently bought an older property, read what to replace after buying an older home to sequence the bigger items.
