How much should I budget annually for home maintenance?

The traditional rule is 1 to 3 percent of the home's value per year, averaged across a decade. Some years will be lower; others you'll replace a water heater and blow through the budget.

What's the single most-overlooked maintenance task?

Flushing the water heater. Almost no one does it, and it dramatically extends tank life and efficiency.

Can I do most maintenance myself?

Yes for filter changes, gutter cleaning, caulking and detector batteries. Hire a pro for HVAC service, roof work, and anything gas-related.

How often should I really change HVAC filters?

Every one to three months, depending on pets, allergies and filter type. Check monthly — if it's grey, it's time.

Seasonal Home Maintenance Checklist for Every Homeowner

Most of the expensive repairs I got called out for in 22 years as a contractor could have been prevented by two hours of maintenance a season. Not the fun kind. The boring kind — clean the gutters, change the filter, drain the sediment out of the water heater.

This is the checklist I keep taped inside my own utility closet. It's short on purpose. A list you'll actually do beats a perfect list you won't.

Spring (March–May)

Walk the roof line from the ground with binoculars. Look for lifted shingles, damaged flashing around vents, and any sagging gutters. Book a pro for anything you can't reach.

Clean gutters and downspouts. Confirm water flows away from the foundation, not toward it.

Service the AC before the first hot week. Change the filter. Clear vegetation from around the condenser.

Check exterior caulking around windows and doors. Recaulk any gaps before summer storms.

Summer (June–August)

Test smoke and CO detectors, replace batteries. Do this every June and every December.

Check the dryer vent hose and outdoor flap. Lint buildup is a real fire hazard.

Inspect the deck or patio. Look for loose boards, popped nails, wobbly rails. Tighten and repair now, not before your July 4th cookout.

Drain a few gallons off the water heater to flush sediment. Ten-minute job, meaningfully extends the tank's life.

Fall (September–November)

Second gutter cleaning after the leaves drop. Skip this and you're inviting ice dams.

Shut off and drain exterior hose bibs. Disconnect hoses. A burst pipe in January is a five-figure mistake.

Service the furnace or heat pump. Book it in September — HVAC calendars fill fast.

Reverse ceiling fan direction (clockwise, low speed) to push warm air down.

Winter (December–February)

Walk the basement or crawlspace weekly during the first cold snap. Catch a small leak before it becomes a flood.

Check attic ventilation and insulation gaps if you see icicles forming — those are usually a sign of heat escaping.

Re-test smoke and CO detectors.

Review your home insurance policy while you're inside anyway. Update the inventory list every couple of years.

Expert tips

•Put the checklist on a shared calendar with reminders. A habit that lives in your head doesn't get done.
•Keep a running note of maintenance dates in the utility closet. Future you (or the next owner) will be grateful.
•Buy a five-pack of HVAC filters at a time. You'll change them more often when they're already in the house.
•Take photos after each maintenance session. If something fails in a year, you know exactly when you last checked it.

Common mistakes to avoid

✕Skipping fall gutter cleaning to avoid the ladder trip. The repair bill for ice damming is enormous.
✕Ignoring small water stains on ceilings — they always come from somewhere and always get worse.
✕Waiting to service the HVAC until it fails. Emergency service is triple the price.
✕Doing maintenance on the roof or ladder alone. It's the leading cause of homeowner injuries.
