Would your home pass a home inspector's 60-second walkthrough? Try these 7 checks

Home inspectors don't need hours to spot trouble. Within the first minute of walking through a house, most seasoned professionals have already clocked a handful of red flags simply by scanning outlets, sniffing the air, and glancing at a few key spots most homeowners never think twice about.

The instincts they've built over thousands of inspections aren't magic. They're pattern recognition, and you can borrow a version of it yourself.

A national survey found that 86% of home inspections turned up something that needed fixing, which means the odds are stacked against any house being flawless. The good news is that most of what trips up an inspection is minor, cheap, and fixable in an afternoon.

Here are seven checks that mirror what a trained eye looks for the moment they step inside.

Check your outlets near water for the test and reset buttons

Ground fault circuit interrupter outlets, the ones with small "test" and "reset" buttons, are one of the first things an inspector's eyes go to in kitchens and bathrooms. The current NEC mandates GFCI protection for receptacles serving bathroom countertops and kitchen countertops.

If your outlets near sinks are the plain, flat kind with no buttons, that's an immediate flag on almost any inspection report. This isn't a rare oversight either.

Missing GFCI outlets are a common occurrence in homes and are generally easily remedied, though they act as an important first defense against electrical overload. The rules have also tightened recently: the 2023 update of the National Electrical Code requires GFCI protection in all kitchen receptacles, expanding the earlier requirements.

If your house predates that update, don't panic, just know it's likely to come up.

Look up at your smoke and carbon monoxide detectors

Smoke detectors seem like a permanent fixture, but they age out quietly. Inspectors often find smoke and carbon monoxide detectors that are either expired or missing altogether, since these units generally have a 7 to 10 year life expectancy and tend to turn a cream color as they age.

If yours look yellowed or you can't remember installing them, that's your answer. Nationally, this is a widespread issue rather than an isolated one.

The percentage of homes with outdated or faulty smoke detectors is approximately 25%, according to industry data. A quick fix involves checking the manufacture date printed on the back of each unit and swapping out anything older than a decade, plus confirming there's one in every bedroom, a rule many local codes now require.

Scan the roofline and attic for early warning signs

Roofing tops nearly every list of common inspection findings, and for good reason. The most common problems associated with inspections are related to the roof, at roughly one in five inspections, followed closely by electrical and window issues.

An inspector will glance at shingle condition, sagging lines, and flashing around chimneys before they even step inside. Age matters just as much as appearance.

The average lifespan of a home's roof before repair is needed is approximately 20 to 25 years, so if you don't know when yours was last replaced, that's worth finding out before a buyer's inspector does. Peek into the attic too, since the condition of the attic space is a common concern flagged by nearly half of inspectors during their evaluations.

Test how your water heater and visible plumbing hold up

Plumbing problems are less dramatic than a leaking roof but almost as common. One in three home inspections find some issue with the home's plumbing system, ranging from slow drips under sinks to corroded shutoff valves that won't turn.

Inspectors will often crouch down and check the base of the water heater tank for rust stains or moisture. Moisture issues in general show up more than most homeowners expect.

Fifty five percent of inspections report small to moderate moisture issues somewhere in the home, and plumbing is frequently the source. A five minute check under every sink and around the water heater base can catch a slow leak before it becomes a much bigger repair bill.

Open your electrical panel and note its age

The electrical panel is one of the quietest but most telling parts of a walkthrough. Every home has some sort of electrical panel present, and most modern homes use circuit breakers in place of the older fuse-style panels.

An inspector will open the panel cover, check for signs of scorching, and note the brand and age. Older panels draw extra scrutiny for a reason.

Homes with older electrical panels, over 20 years old, are inspected twice as often for safety issues compared to newer systems. If your panel still uses fuses rather than breakers, or if the labeling is faded and inconsistent, expect that to be flagged and possibly recommended for an electrician's review.

Walk the perimeter and check how the ground slopes

Grading is easy to overlook because it's just dirt, but inspectors treat it seriously. Grading refers to the ground surrounding a home and the direction it slopes, and inspectors look for positive grading, meaning the ground slopes away from the house.

Negative grading, where water pools toward the foundation instead of away from it, is one of the quieter causes of long term moisture damage. The fix doesn't have to be complicated.

Optimally, the ground around a home should be about six inches higher than ten feet away, though when that isn't possible, creative landscaping can help divert water away from the house. Walk around your foundation after a heavy rain and see where puddles form.

That's usually the clearest sign something needs regrading.

Check window and door seals for drafts and fogging

Windows rank among the most frequently cited issues on inspection reports, and the reasons are almost always small but noticeable. Fifty percent of inspections find issues related to window and door seals, which often show up as drafts, condensation between glass panes, or doors that no longer close snugly.

Foggy double-pane windows are a particularly clear tell, since it usually means the seal between the panes has failed. These issues rarely threaten a sale on their own, but they add up in an inspector's notes and can become a bargaining chip.

Window defects were identified in close to one in five inspections nationally, putting them right alongside roofing and electrical problems as one of the top three categories inspectors flag. A simple test is running your hand around window frames on a cold or windy day to feel for air movement.

Final thoughts

None of these seven checks require special tools or training, just a willingness to look at your home the way a stranger paid to find flaws would look at it. Most of what turns up is inexpensive to fix, and catching it yourself means you control the timeline and the cost rather than scrambling during a real estate negotiation.

A house doesn't need to be perfect to pass muster, it just needs an owner who's paid attention to the small things before someone else does.
