A solid monthly home maintenance routine takes about an hour and runs to ten tasks: testing safety devices, checking for leaks, cleaning a few key components, and walking your home for new damage. It’s the cheapest insurance you can buy against the surprise repairs that hit roughly 60% of homeowners every year — and unlike most checklists you’ll find online, none of these belong on a separate “seasonal” or “annual” list.

Why a monthly checklist is worth your hour

Skip a few months and the cost compounds quickly. Bankrate’s 2025 Hidden Costs of Homeownership Study puts the average annual hidden cost — maintenance, insurance, taxes, utilities — at about $21,400. A 2022 Ipsos survey for Hippo Insurance found 60% of homeowners paid for an unexpected repair in the prior year, with average costs near $4,000.

The pattern behind those numbers is almost always the same: a slow leak, a clogged filter, a dead detector battery, an attic that’s been quietly filling with squirrels. Caught early, any of these are a quick fix. Caught after a year, and the cost is exponential.

Fannie Mae recommends budgeting 1% to 4% of your home’s value every year for maintenance and repairs. The lower end of that range is realistic if you keep up with maintenance, but skip the routine and the cost drifts toward 4%.

When Jonathan and I started Hank, the first homes we used as test cases were our own. Mine was a fixer-upper condo in Atlanta, and for the first year I kept track of repairs across Google Drive, my inbox, and a few half-dead text threads. By month six I couldn’t tell you the last time I’d checked anything.

The 10-task monthly home maintenance checklist

Run the list once a month — same day if you can, like the first Saturday. None of these takes longer than ten minutes, most are inspection-only, and none require a contractor. The order matters less than actually doing them.

#	Task	Typical time	Tool	What it prevents
1	Test smoke and CO detectors (press the button)	2 min	None	Disabled alarms during a fire or leak
2	Check under every sink for leaks or moisture	5 min	Flashlight	Cabinet rot, mold, drywall damage
3	Clean the garbage disposal (ice + lemon, cold water)	3 min	Ice cubes	Clogs and odor
4	Pour water down rarely-used drains	2 min	None	Sewer-gas smell from dried P-traps
5	Walk the perimeter for new cracks, paint failure, missing caulk	10 min	Phone for photos	Water intrusion, pest entry
6	Test GFCI outlets (kitchen, bath, exterior, garage)	3 min	None	Shock hazard, code failure at sale
7	Vacuum refrigerator coils and the dryer lint trap behind the screen	10 min	Vacuum + crevice tool	Energy waste, dryer fires
8	Pull and clean the range hood filter (dishwasher or degreaser)	5 min	Dishwasher	Grease fire risk, weak ventilation
9	Check the fire extinguisher pressure gauge (green = good)	1 min	None	Dead extinguisher in an emergency
10	Run the sump pump (pour a bucket of water in)	5 min	Bucket	Basement flood during the next big rain

That’s less than an hour and makes a huge difference over the long run. A few tips to highlight:

• Do not skip the leak walk. A small drip under a sink can soak a baseboard in a month.
• Don’t skip the dryer-lint cleanup behind the screen. Lint that gets past the screen builds up in the duct, and a clogged duct is the leading cause of dryer fires.
• Take photos on the exterior walk. Comparing month-to-month photos catches new damage that “looks the same” in the moment.

Quarterly items to keep in mind

A few items get pinned onto the monthly checklist only when they’re due, so the core list stays at ten:

• HVAC filter — every 1 to 3 months. This is the most common monthly task in other checklists, but for most homes once a quarter is correct. We have a full guide on how to change an HVAC filter, including how MERV ratings and pets change the cadence.
• Water heater — flush a quart every 3 to 6 months. Crack the drain valve and run a quart into a bucket to clear sediment. NAHB lists water heater life expectancy at about 10 years; doing this is most of why some make it past 15.
• Gutters — twice a year for most homes, four times if you have a lot of trees.
• Smoke-detector batteries — every 6 months. Swap the batteries even if the test is passing. The detector itself should be replaced at 10 years.

Tools to keep in one place

You don’t need much. Keep these in one spot so the routine doesn’t stall while you hunt for a flashlight:

• A bright LED flashlight or headlamp
• A wet/dry vacuum with a crevice attachment
• A phone or small notebook for the perimeter walk
• A spare HVAC filter for next quarter (saves a separate trip)
• A digital multimeter (optional, but useful for outlet testing if you want to be thorough)

How long this should realistically take

About 45 to 60 minutes the first month, then 30 to 45 once you know your home. The exterior walk and refrigerator-coil cleaning are the two longest tasks. If a month’s check turns up something new — a soft spot under a sink, a rusted hose-bib, an outlet that won’t reset — it goes on a separate “to fix” list. Don’t try to fix and inspect in the same hour. You’ll cut the inspection short, every time.

How to keep the routine

The list isn’t the hard part. Remembering is. Most homeowners I talk to have tried a routine like this and dropped it by month four. Two things make it stick:

1. Tie it to a calendar event you already keep. First Saturday of the month works for a lot of people because that is already home errand day. Pick a date, set a recurring calendar reminder, and don’t move it.
2. Track what you actually checked. Skipping a month is fine if you know you skipped. The problem is forgetting that you forgot. Even a paper checklist on the inside of a closet door beats nothing.

This is the gap Hank is built to fill. Tell us about your home and what’s in it, and we generate a maintenance schedule that knows the difference between your home and your neighbor’s. Your monthly hour stops being a checklist you have to remember and becomes a notification with insights on what to check.

Frequently asked questions

How long should monthly home maintenance actually take? Plan for 45 to 60 minutes the first time and 30 to 45 once you have a rhythm. Most tasks are inspection or two-minute cleaning, not repairs.

What’s the single most important monthly task? Walking your home and looking under every sink. Roughly 60% of homeowners hit a surprise repair every year per the Ipsos / Hippo Insurance survey, and water is the cause behind the most expensive ones. A monthly glance at sink cabinets is what stops a $30 valve from becoming a $3,000 floor job!

Do I really need to change the HVAC filter every month? Usually not. Most homes are fine on a 3-month cadence; pets, allergies, or heavy use shorten that to 1 to 2 months. Our HVAC filter guide walks through the rules. Don’t burn a $15 filter on a 30-day cycle if your home doesn’t need it.

What does monthly home maintenance cost per year? Supplies — replacement filters, a bottle of degreaser, a few odds and ends — run roughly $150 to $300 a year for an average home. Fannie Mae recommends budgeting 1% to 4% of your home’s value annually for maintenance overall, including the bigger quarterly and seasonal items. The monthly-task supplies are a small fraction of that.

Is this checklist different for a townhouse or condo? Yes — drop the exterior walk, gutters, and sump pump. Add HOA-specific items: storage-room ventilation, in-unit shutoff valves, and balcony or patio drains. The other seven items are the same. If your HOA covers the exterior, your monthly hour just got shorter.

A monthly hour is the cheapest insurance a home will ever ask of you. The trick isn’t doing the work — it’s not forgetting. Join the Hank waitlist and we’ll handle the remembering for you.
