The Complete Home Maintenance Checklist by Season

Owning a home is the largest investment most people will ever make — and like any investment, it requires ongoing maintenance to hold its value. The average homeowner should budget 1–2% of their home's value per year for maintenance and repairs. Skip the maintenance, and that number climbs fast.

The good news: most home maintenance tasks are simple, inexpensive, and take less than an hour. The key is doing them at the right time of year. This checklist organizes everything by season so you always know what to tackle next.

Your home faces different stresses in different seasons. Winter puts pressure on your heating system, pipes, and roof. Summer strains your cooling system and exterior surfaces. Doing the right maintenance at the right time prevents the kind of failures that turn into emergency calls — and emergency bills.

A $15 furnace filter replaced in October prevents a $3,000 furnace repair in January. A $200 gutter cleaning in November prevents a $4,000 foundation repair in spring. The math is straightforward.

Spring is the time to assess winter damage and prepare for warmer months.

• Inspect the roof — look for missing, cracked, or curling shingles; check flashing around chimneys and vents
• Clean gutters and downspouts — remove debris from winter; check for sagging or damage
• Check downspout drainage — water should discharge at least 6 feet from the foundation
• Inspect the foundation — look for new cracks, especially horizontal cracks in block foundations
• Check exterior caulking — around windows, doors, and where siding meets trim; re-caulk where cracked or missing
• Inspect wood siding, trim, and decks — look for rot, peeling paint, or loose boards
• Check driveway and walkways — fill cracks before they expand with freeze-thaw cycles
• Inspect fencing — tighten loose posts, replace damaged boards

• Schedule AC tune-up — before the first hot day, have a technician check refrigerant levels, clean coils, and test the system
• Replace HVAC filter — every 1–3 months depending on filter type
• Clean AC condenser unit — remove debris from around the unit; gently rinse fins with a hose
• Test ceiling fans — switch to counterclockwise rotation for summer (pushes cool air down)

• Check for leaks under sinks — look for water stains, soft cabinet floors, or musty smell
• Test outdoor hose bibs — turn on and check for leaks; if they froze over winter, they may need repair
• Inspect water heater — look for rust, corrosion, or moisture around the base; test the pressure relief valve
• Check sump pump — pour water into the pit to test that it activates; replace battery backup if present

• Test smoke and CO detectors — replace batteries; replace detectors older than 10 years
• Check fire extinguisher — verify pressure gauge is in the green zone
• Inspect attic — look for signs of moisture, pest activity, or inadequate ventilation
• Check window and door seals — replace weatherstripping where worn

Summer is about protecting your home from heat, moisture, and pests.

• Inspect and clean deck or patio — power wash, check for loose boards or fasteners, re-seal if needed
• Check window screens — repair or replace torn screens before mosquito season peaks
• Trim trees and shrubs — keep branches at least 6 feet from the house; overhanging branches damage roofs and provide pest access
• Check irrigation system — inspect sprinkler heads for damage or misalignment; adjust coverage to avoid watering the foundation
• Inspect exterior paint — look for peeling, bubbling, or fading; address before fall

• Check AC performance — if the system is struggling to maintain temperature, schedule a service call before the hottest weeks
• Replace HVAC filter — especially important in summer when the system runs constantly
• Clean dryer vent — lint buildup is a fire hazard; clean the duct from the dryer to the exterior vent

• Check for slow drains — address before they become full blockages
• Inspect washing machine hoses — replace rubber hoses older than 5 years with braided stainless steel
• Check dishwasher door seal — look for cracks or mold; clean with white vinegar

• Inspect foundation and exterior walls — seal any gaps larger than 1/4 inch where pests can enter
• Check attic and crawl space vents — screens should be intact to prevent nesting
• Look for signs of termites — mud tubes along the foundation, hollow-sounding wood, or discarded wings near windows

Fall is the most critical maintenance season. The work you do now determines how your home handles winter.

• Schedule furnace or boiler tune-up — before the first cold snap; technician will clean, inspect, and test the system
• Replace HVAC filter — start the heating season with a fresh filter
• Bleed radiators (if you have hot water heat) — release trapped air for more efficient heating
• Test thermostat — switch to heat mode and verify it responds correctly; consider upgrading to a programmable or smart thermostat

• Clean gutters — after leaves have fallen (late October/November); clogged gutters cause ice dams and foundation damage
• Inspect roof before winter — address any issues before snow and ice make repairs impossible
• Caulk and seal — check all exterior penetrations (pipes, wires, vents) and re-caulk where needed
• Drain and store garden hoses — disconnect from hose bibs to prevent freeze damage
• Shut off and drain irrigation system — in freeze-prone climates, have it professionally blown out
• Check exterior lighting — shorter days mean you'll rely on outdoor lighting more; replace bulbs and check fixtures

• Locate your main water shutoff — know where it is before you need it in an emergency
• Insulate exposed pipes — in unheated spaces like garages, crawl spaces, and exterior walls
• Drain outdoor water features — fountains, ponds, and irrigation systems

• Schedule chimney inspection and cleaning — before the first fire of the season; creosote buildup is a fire hazard
• Check damper operation — should open and close smoothly; a stuck damper wastes heat
• Stock firewood — store away from the house to avoid pest problems

• Check weatherstripping — replace where worn; a simple test is to close a door on a dollar bill — if it slides out easily, the seal is inadequate
• Install storm windows (if applicable) — or check that existing storm windows are in good condition
• Check attic insulation — inadequate insulation is the leading cause of ice dams and high heating bills

Winter maintenance is mostly about monitoring and responding to problems quickly.

• Know the signs of freezing pipes — reduced water flow, frost on pipes, or unusual sounds in the walls
• Keep cabinet doors open — under sinks on exterior walls during extreme cold to allow warm air to reach pipes
• Maintain minimum indoor temperature — keep the thermostat at 55°F or above even when away
• Check for ice dams — ridges of ice at the roof edge that can force water under shingles; address with a roof rake if safe to do so

• Replace HVAC filter — monthly during heavy heating season
• Test smoke and CO detectors — monthly; CO risk increases with heating system use
• Check for drafts — use a candle or incense stick near windows and doors to find air leaks
• Monitor attic — check for moisture or frost buildup, which indicates inadequate ventilation

• Review home maintenance records — what was done this year? What needs attention next year?
• Get quotes for spring projects — contractors are less busy in winter and may offer better pricing
• Review homeowner's insurance — make sure coverage reflects current home value and any improvements made

• Drain and flush water heater — removes sediment that reduces efficiency and shortens lifespan
• Test GFCI outlets — in bathrooms, kitchens, garages, and outdoors; press the test button and verify the outlet loses power
• Inspect electrical panel — look for signs of heat damage, corrosion, or tripped breakers; call an electrician for anything concerning
• Check attic insulation depth — most homes need R-38 to R-60 in the attic; inadequate insulation is one of the most cost-effective things to address
• Inspect crawl space (if applicable) — look for moisture, pest activity, or damaged insulation
• Clean refrigerator coils — vacuum the coils on the back or bottom; dusty coils reduce efficiency
• Test garage door auto-reverse — place a 2x4 flat on the ground; the door should reverse when it contacts it

Some maintenance tasks require licensed professionals — both for safety and because DIY work on certain systems can void warranties or create liability:

• Electrical work beyond replacing outlets or switches
• Gas line work of any kind
• HVAC repairs (not just filter replacement)
• Roof repairs beyond minor patching
• Structural concerns — cracks in the foundation, sagging floors, or bowing walls
• Chimney cleaning and inspection

The most valuable thing you can do as a homeowner is keep a simple record of what maintenance was done and when. A spreadsheet or even a notebook works fine. Include:

• Date of service
• What was done
• Who did it (contractor name and contact)
• Cost
• Next service date

This record is invaluable when you sell your home (buyers love documented maintenance history), when filing insurance claims, and when diagnosing recurring problems.

Your home is worth protecting. A few hours of maintenance each season is the cheapest insurance policy you can buy.
