5 Things You're Probably Not Doing as a Homeowner (But Should Be)

Here's a confession to get us started: plenty of people who write homeowner tips for a living have stood in a spreading puddle at 11 p.m., phone flashlight in hand, with no idea where their main water shutoff was. Owning a home doesn't come with a syllabus. You learn the important lessons the expensive way, usually on a holiday weekend when every plumber in town is booked.

The homeowner tips that actually save you money are almost never the fun ones. Nobody daydreams about registering a dishwasher or rereading an insurance policy. But the five unglamorous tasks below are often the difference between an annoying Tuesday and a five-figure claim, and every one of them costs little or nothing.

And none of this is a judgment. If you're currently doing zero of the five, you're in good company with most homeowners we know. The point isn't guilt. The point is that each item takes minutes to fix, and the only bad time to fix it is after something goes wrong.

Why the best homeowner tips are the boring ones

There's a pattern to all five of these tasks: they're invisible when they work. Nobody compliments your tagged shutoff valve. Your home inventory does absolutely nothing, possibly forever. That invisibility is exactly why they get skipped, and exactly why they're worth so much on the one day they matter.

Here's the whole list at a glance:

Task	Time	Typical cost	What it protects you from
Find and tag the main water shutoff	10 minutes	Free	Five-figure water damage
Build a home inventory	Roughly 2 hours	Free	An undocumented insurance claim
Register your appliances	About 5 minutes each	Free	Missed recalls and warranty disputes
Test the sump pump	10 minutes, twice a year	Free	A flooded basement
Review your insurance	30 minutes a year	Free	Finding out you're underinsured

Total investment: an afternoon, give or take. Let's take them one at a time.

1. Find your main water shutoff before the flood

Water damage is consistently one of the most common home insurance claims, and once flooring, drywall, and cabinets are involved, a claim can easily run into five figures. A burst supply line can release several gallons a minute. The difference between shutting the water off in ninety seconds versus twenty minutes is the difference between a wet floor and a renovation.

So, today, go find the valve. Common spots:

• In the basement or crawl space, along the wall that faces the street
• Near the water heater or the laundry hookups
• In the garage
• In warmer climates, outside in a covered box near the meter

Once you find it, actually turn it. Older gate valves (the round-wheel kind) can seize after years of never moving, and you want to discover that now, not mid-flood. If it's stuck or weeping, a plumber can typically swap in a quarter-turn ball valve for roughly $150 to $350, which is some of the best money you'll ever spend on this house.

Then tag it. A label on a zip tie works fine. Show everyone in the household where it is, kids included. If you've just moved in, this belongs at the very top of your first 30 days checklist.

2. Keep a home inventory, serial numbers included

Imagine your insurer asks you to list everything in your kitchen, from memory, a week after a fire. Every gadget, every pan, roughly what you paid, and when. That's essentially what a claim looks like without an inventory, and it's why people routinely recover less than their policies actually entitle them to.

The lazy version takes fifteen minutes: walk through your house filming a slow video on your phone, narrating as you go, opening drawers and closets. Done. That alone puts you ahead of most homeowners.

The better version takes roughly two hours. Photograph the model and serial number plates on anything worth more than a couple hundred dollars, and keep receipts for the big stuff. We wrote a full walkthrough in our home inventory guide if you want the step-by-step.

Wherever the inventory lives (a spreadsheet, a cloud folder, or an app like Casamia that keeps serial numbers alongside your receipts and warranty documents), make sure a copy exists somewhere other than inside the house it's protecting.

3. Register your appliances, even though it feels like junk mail bait

That registration card in the box reads like a marketing trick, and honestly, it partly is. Register anyway, and here's why: registration is how manufacturers find you when something gets recalled. Appliance recalls happen more often than most people realize, and they're frequently for genuinely scary stuff — dryers with fire risks, ranges that tip, dehumidifiers that overheat.

An unregistered appliance means the recall notice goes to whoever bought the thing originally, or to nobody at all.

Registration also timestamps your purchase, which matters when you're making a warranty claim two years later and can't find the receipt. It typically takes about five minutes per appliance on the manufacturer's website, with the model and serial number in hand. Knock them all out in one sitting while watching something forgettable.

While you're at it, get clear on what that warranty actually covers versus your homeowners policy. The gaps are bigger than most people expect, and we broke them down in home warranty vs. manufacturer warranty vs. insurance.

4. Test your sump pump before the storm does it for you

Skip ahead if you don't have a basement. If you do, and there's a pit with a pump in it, that pump is quietly responsible for keeping your lowest floor dry, and it will fail eventually. Most last roughly 7 to 10 years, and they have a knack for dying during the first big storm after a long dry spell, which is exactly when you find out.

The test takes ten minutes. Pour a five-gallon bucket of water into the pit. The float should rise, the pump should kick on, the water should drain, and the pump should shut off. That's the whole procedure. Do it twice a year, ideally early spring and fall.

If the pump is dead or dying, a replacement unit typically runs $150 to $400, or roughly $400 to $700 installed. A battery backup system, for when the power fails during the same storm that's flooding your yard, typically runs $600 to $1,500 installed. That sounds steep until you price out a flooded finished basement, where cleanup alone typically starts in the low thousands and climbs fast.

One more thing worth knowing: standard homeowners insurance typically does not cover groundwater flooding or sump pump failure unless you've added a specific water backup endorsement. Which brings us to number five.

5. Give your insurance policy an annual once-over

For most of us, the renewal notice arrives, the premium is higher than last year, we sigh, and we pay. The policy itself goes unread for years while the house it covers keeps changing.

Once a year, at renewal, spend 20 to 30 minutes on four questions:

1. Is the dwelling coverage still enough to rebuild? Construction costs have climbed a lot in recent years, so a limit set five years ago may be badly short today.
2. Does the policy know about your improvements? A finished basement, a new deck, a renovated kitchen. If it's not reflected, you may be underinsured.
3. Do you have a water and sewer backup endorsement? It typically costs $50 to $250 a year and covers the exact basement scenario from the last section.
4. Is your deductible still right for your savings? Raising it can trim the premium, but only if you could comfortably pay it tomorrow.

None of this requires expertise. Call your agent, ask the four questions, take notes. It's the least glamorous half hour of your year, and quite possibly the highest-leverage one.

The homeowner tips that stick are the scheduled ones

Here's the honest failure mode: you read a list like this, nod along, and do none of it. Not because you disagree, but because there's never a moment when any of it becomes urgent. That's not a character flaw. It's just how invisible tasks work.

So borrow the trick that works for everything else in life and put these on a calendar. "Test sump pump" in April and October. "Insurance review" the week your renewal lands. "Update home inventory" once a year. This is the kind of thing Casamia was built for, with reminders that sync straight to your Google or Apple Calendar, but a plain recurring calendar event works too. The tool matters far less than the trigger.

Fifteen minutes of setup, once, and future-you never has to remember any of this cold again.

The bottom line

These five tasks cost almost nothing, take about one combined afternoon, and quietly stand between you and some of the most expensive bad days a house can produce. Find the shutoff and tag it. Film the inventory. Register the appliances, test the pump, and ask your insurance agent four questions a year. Then schedule all of it, so the remembering happens automatically and you can get back to the parts of homeownership you actually enjoy.
