The houses we see in the best shape are not owned by people who do big projects. They are owned by people who do small ones on a schedule. A filter here, a gutter there, a quick look at the roof after a storm. None of it takes long. The trick is remembering.
Here is the calendar we use. For a printable month-by-month version, see our home maintenance calendar tool.
Every month
- Test smoke and CO alarms (press and hold the test button)
- Test GFCI outlets (press TEST, then RESET)
- Check the furnace or AC filter and change it if dirty
- Run water in unused sinks and tubs so drain traps do not dry out
- Look under sinks for drips
Spring
- Clean gutters and downspouts once trees finish dropping blossoms and seeds
- Walk the roof line from the ground with binoculars after winter storms
- Check the foundation for new cracks and grading that slopes toward the house
- Turn outdoor water back on and check for leaks inside
- Inspect the deck, railings and stairs. See our deck check.
- Have the air conditioning serviced before the first hot week
Summer
- Re-caulk around windows and trim where it has cracked
- Wash and seal or stain the deck if water no longer beads on it
- Clean the dryer vent from end to end
- Clean bathroom exhaust fans and check they vent outside
- Trim trees and shrubs back from the roof, siding and AC unit
- Check the attic for heat buildup, pests and roof leaks
Fall
- Service the furnace or heat pump
- Replace worn door weatherstripping and sweeps
- Disconnect hoses and winterize outdoor faucets. See our winterizing post.
- Clean gutters again after the leaves drop
- Seal gaps where pipes and cables enter the house
- Have the chimney inspected if you burn wood
- Check alarm dates; replace any past the manufacturer’s replacement date
Winter
- Watch for ice dams and large icicles after snow. See why they form.
- Keep heating vents and returns clear of furniture
- Check space heaters and cords before each use
- Keep the area around the furnace and water heater clear
- Notice drafts on windy days and add them to the spring list
- Know where your main water shut-off is, in case a pipe freezes
Once a year, have someone look
A yearly once-over by someone who repairs houses catches things you walk past every day: a pipe boot cracking on the roof, a deck ledger with no flashing, a water heater starting to rust at the base. It is the cheapest way to find a problem while it is still small.
Our guides are general information for typical homes. Codes, permits and conditions vary, so check local rules, and leave gas, main electrical panel and structural work to a licensed professional.
