Most of us aren’t walking around our houses every Sunday with a clipboard, checking every pipe, hose, filter, and gutter.
I certainly don’t want to pretend we are.
But I do think there’s something useful about taking 20 minutes every once in a while to actually pay attention to your house.
Because houses give us clues.
A drip under the sink.
A toilet that suddenly won’t stop running.
A strange smell.
A new stain on the ceiling.
A washing machine hose that looks different than it did a few months ago.
Water collecting somewhere outside that didn’t used to.
You don’t have to be particularly handy to notice those things.
You just have to pay attention.
So here’s the 20-minute home check I wish I did every week… and probably should. 😂
Start Where Water Likes to Hide
You don’t need to start with the most complicated part of your house.
Start with the places where a small leak can quietly sit unnoticed.
Look under the sinks
Open the cabinets underneath your kitchen and bathroom sinks.
Look for:
- Drips or active leaks
- Dampness
- Water stains
- Swollen or damaged cabinet material
- Corrosion around connections
You don’t need to know exactly what’s wrong.
If something is wet when it shouldn’t be, you’ve found something worth investigating.
Regularly looking for leaks is a simple part of home maintenance, and the EPA specifically recommends checking places such as under-sink plumbing for signs of leaks.
Listen to your toilets
This one takes almost no time.
If you hear a toilet running when nobody has flushed it recently, don’t automatically tune it out.
A running toilet can indicate a leak, and some toilet leaks aren’t obvious just by looking at the toilet.
You don’t necessarily have to take the tank apart immediately.
Just noticing that something has changed is a good first step.
Give the Washing Machine a Quick Look
Your washing machine moves a lot of water through a relatively small space.
Take a quick look around the machine and its connections.
Is there any moisture on the floor?
Do the hoses or connections look damaged?
Is there anything that looks different from the last time you paid attention?
You don’t need to pull the entire machine out every week or start replacing parts just because you’re doing a home check.
You’re looking for something unusual.
If you see an active leak or damaged supply line, that’s the point where it’s worth addressing the problem rather than waiting for it to get worse.
Look Up
Now take a quick walk through the main rooms of your house and actually look at the ceilings and walls.
You’re not inspecting every square inch.
You’re looking for changes.
A new stain.
A discolored patch.
Peeling or bubbling paint.
A spot that looks different from the last time you noticed it.
The same goes for windows and other areas where moisture can show up.
A stain doesn’t automatically tell you where the water came from. That’s important.
The visible problem isn’t always the source of the problem.
If you notice something new, don’t simply paint over it and hope it disappears.
Figure out what changed.
Pay Attention to What You Smell
Your nose can sometimes notice something before your eyes do.
A new musty smell is worth paying attention to, especially if you can’t identify an obvious reason for it.
Musty odors can be associated with mold or moisture problems, and the EPA recommends investigating the source rather than simply masking the smell. US EPA
That doesn’t mean every strange smell means you have mold.
It means your house is giving you information.
Pay attention to it.
The same goes for unusual smells coming from drains, appliances, mechanical equipment, or other parts of the house.
You don’t need to diagnose the problem from the smell alone. You just need to notice that something has changed.
Check Your HVAC Filter
This one is less exciting, but it’s easy to forget.
Take a look at your HVAC filter.
How often it needs to be changed depends on the system, filter, and how the home is used, so don’t assume every filter needs the same schedule. ENERGY STAR recommends checking filters monthly and replacing or cleaning them according to the equipment and filter requirements.
If the filter is visibly dirty, that’s your reminder to deal with it.
And if you’re not sure what your system requires, check the manufacturer’s instructions or ask your HVAC professional.
Again, this isn’t about becoming an HVAC technician.
It’s about noticing when basic maintenance has been forgotten.
Walk Outside
This is especially useful during rainy weather.
Take a quick walk around the outside of your house and look at what the water is doing.
Are gutters overflowing?
Are downspouts sending water somewhere it shouldn’t?
Is water collecting near the foundation?
Are there areas of the yard that stay unusually soggy?
This doesn’t mean every puddle is a major drainage problem.
You’re looking for patterns and changes.
Renton’s surface-water system is designed to manage stormwater and reduce flooding, but homeowners still need to pay attention to drainage and water movement around their own properties. The City also identifies gutters and downspouts as part of its residential weatherproofing work.
And sometimes rain is actually helpful.
It lets you see where the water is going in real time.
You Don’t Have to Fix Everything You Notice
This might be the most important part of the whole exercise.
The purpose of a 20-minute home check isn’t to turn you into a contractor.
It’s to help you notice when something has changed.
You might see moisture under a sink and have no idea why it’s there.
You might notice a ceiling stain but have no idea where the water is coming from.
You might hear a strange sound from an appliance.
You might discover that water is collecting in the same place outside every time it rains.
That’s okay.
You don’t necessarily need to know how to fix the problem.
You need to know when something doesn’t look, sound, smell, or behave the way it normally does.
When to Call a Professional
There are plenty of basic maintenance tasks homeowners can handle themselves.
But there are also times when the smartest DIY decision is not doing it yourself.
I’d bring in the appropriate professional for things like:
- Electrical problems or wiring concerns
- Significant plumbing leaks or plumbing problems you can’t identify
- Roofing problems, especially anything requiring roof access
- Structural concerns
- HVAC repairs or problems beyond basic filter maintenance
- Persistent moisture when you can’t identify the source
- Suspected mold or significant moisture damage
You can learn a lot from YouTube.
That doesn’t mean YouTube should be your contractor.
If you don’t know what you’re looking at, or the problem involves a major home system, get someone qualified to evaluate it.
The EPA similarly recommends professional assistance when moisture or mold problems require more than basic homeowner-level action.
Your House Doesn’t Need a Weekly Inspection
Despite the title of this article, I don’t think you need to set a recurring Sunday appointment with your house.
The 20 minutes is a framework, not a rule.
Maybe you do this once a week.
Maybe it’s every couple of weeks.
Maybe you do a quick version after a big rain, before leaving for vacation, or when you realize you’ve been ignoring the house for longer than you’d like to admit.
The point is simply to build the habit of looking.
Because small problems are often much easier to deal with when they’re still small.
You Don’t Have to Be Handy. You Just Have to Pay Attention.
I think we sometimes make homeownership sound like you need to know how to fix everything.
You don’t.
You don’t have to know how to repair a toilet, diagnose an HVAC problem, replace a roof, or figure out exactly why water is showing up in your crawlspace.
But you should know your house well enough to notice when something changes.
That’s what this 20-minute check is really about.
Look. Listen. Notice.
You might not know what the problem is.
But catching it early gives you a much better chance of figuring that out before a small clue turns into a much bigger repair.
And honestly, that’s probably 20 minutes well spent.
| You notice… | Your first job is… |
|---|---|
| Water under the sink | Notice where it’s coming from |
| Running toilet | Investigate the leak |
| Ceiling stain | Find the source |
| Musty smell | Look for moisture |
| Dirty HVAC filter | Check/replace as appropriate |
| Standing water outside | Watch where the water is going |
You don’t have to fix everything yourself. You just need to notice when something changes.
