June

Renters live with unanchored furniture because they can't drill.

Your heat comes from burning fuel, which means your house makes carbon monoxide on purpose all winter and exhausts it on purpose — until something interferes: a cracked heat exchanger, a blocked flue, a backdrafting water heater sharing the chimney.

Everything in a modern house has a circuit board in it now — the furnace, the water heater if it's fancy, every appliance with a display.

Here's the thing your semiannual button-test can't tell you: the test button proves the battery and the horn work — not the smoke sensor.

If you don't charge a car at home, close this card — it's not for you, and there's nothing to buy.

Insurance claims run on evidence, and the evidence has a deadline nobody announces: it must exist BEFORE the bad day.

Since 1993, every opener sold has had two independent safety systems: auto-reverse (the door hits something and retreats) and photo eyes (the door won't close through a broken beam).

Your house's era means some or all of its wiring predates modern grounding.

Fire escape planning upstairs comes down to one question: if the stairway is full of smoke, how does each person in each bedroom get down?

Every water disaster starts as a drip you couldn't see: the washing machine hose weeping behind the machine, the water heater rusting through at the base, the supply line sweating inside a vanity.

Every shower puts about a pint of water into the air, and the little fan in the ceiling is the only exit.

You told us you're not sure what kind of water heater you have — join the club; it's the appliance people interact with least and depend on most.

Water heaters ship set by a factory that has never met your household.

Someday — a burst washing machine hose, a split supply line, a frozen pipe letting go — water is going to be spraying inside your house, and every minute it runs costs you real money.

A house your age has a sewer lateral made of whatever the year offered, and none of the options aged gracefully.

Your water meter watches every drop that enters the house, which makes it the cheapest leak-detection technology you'll ever own.

Every toilet and faucet in your house is fed by a small flexible line, and if those lines are gray or black rubber, each one is a little time bomb with a 5–10 year fuse.

You're on well water, which means you are your own water utility — no city lab is checking your water, ever.

Your annual septic walk-through card watches the tank and the pumping schedule.

Behind your washing machine are two hoses under constant pressure, and the factory rubber ones have a service life people don't respect: about five years before the material starts giving up.

Your chimney sweep handles the inside of the flue — this card is about the outside top, which nobody looks at and which quietly determines whether your chimney lasts fifty years or needs rebuilding in fifteen.

You told us you don't know your roof's age — totally normal, most homeowners don't, and nobody hands you a binder at closing with this stuff filled in.

Your gutters can be spotless and still ruin your foundation if the downspouts fire all that roof water straight down at the base of the wall.

You have gutter guards, which means someone — maybe you, maybe the last owner — bought a reduction and was probably sold an elimination.

This card acts on what your siding-and-paint walkaround finds — that one inspects, this one fixes.

Your house is old enough to have real wood windows, and here's what the replacement industry won't tell you: those windows were built from old-growth lumber that outlasts anything sold today, and every part of them is repairable.

Your siding and paint are the house's only raincoat, and raincoats fail at the seams: butt joints, nail heads, window trim, and anywhere wood meets weather.

Siding isn't decorative — it's the raincoat.

In your county's kind of humid summer, mosquitoes don't come from "outside" — they come from your property, seven days after water sits still.

Plants against a house do damage on three quiet channels: they hold moisture against the skin, they abrade whatever they touch in the wind, and they give every pest in the yard a covered highway to your walls.

Desert rain is a different animal.

A house fails differently when nobody's home to hear it.

Every key to your house that existed before closing day is still out there.

You've never actually tested this house's windows and doors — the inspector opened a sample, the sellers stopped noticing years ago.

Every major system in your house has its birthday stamped on a data plate — usually encoded in the serial number — and knowing those dates changes how you spend money for the next decade.

Of everything you inherited from the sellers, the HVAC filter is the item you can reset to factory-new for ten bucks — and one of the most revealing.

Your house has a paper trail, and the first weeks of ownership are when it's easiest to collect — the sellers' agent still answers email, the sellers still remember their vendors, and warranty-transfer windows (some manufacturers give you 60–90 days) are still open.

Somewhere on your property are capped pipes that exist purely for the worst day your plumbing will ever have — and the middle of a sewage backup is the wrong time to learn they exist.

Your breaker panel is the index to your whole electrical system, and right now it's either blank, or — worse — labeled by someone else's memory of a renovation two owners ago.

That red cord hanging from your opener rail is the manual override, and it has a technique.

Your first full month of bills is a diagnostic report about the house, disguised as junk mail.

Everything else on your punch list generates paper and photos: lock receipts, breaker maps, detector dates, meter shots, serial numbers, permit printouts.

You don't know when these detectors were tested, how old they are, or whether the sellers' painter took the batteries out in 2019 and never confessed.

Your find-the-shutoff card covered the inside of the house.
