September

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 burned wood last winter, your flue has creosote in it — that's not a maybe, it's chemistry.

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

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.

You've done the homework by now — found the main water shutoff, exercised the valves, met the gas meter.

Boilers are the longest-lived heat in the business — 30-year-old ones run fine all over the country — but only when someone lays eyes on them once a year.

Your heating system sat idle all summer, and the first cold snap is when every marginal part announces itself.

Say it clearly up front: gas fireplaces and wood fireplaces get different service.

Your heating and cooling system breathes through two sets of openings: supply registers that blow, and return grilles that inhale.

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.

The laundry standpipe — that open vertical pipe the washer's drain hose hooks into — is the most abused drain in the house.

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.

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.

Your sump pump is the appliance version of a smoke detector: it does nothing 360 days a year, and then one night it's the only thing standing between your basement and the water table.

First, the honest gate: if your fridge has no water dispenser and no ice maker, close this card — it's not for your house, and no appliance tech should ever sell you otherwise.

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.

Your metal roof will likely outlive your mortgage — the panels, anyway.

Tile is the marathon runner of roofing — concrete and clay tiles routinely outlast the people who installed them.

A wood roof is the most maintenance-honest roof there is: treat it well and cedar gives you 30–40 years of the best-looking roof on the street; ignore it and it composts in place.

Caulk is the disposable part of your home's skin.

Concrete cracks.

Closing a pool isn't about the water in the bowl — it's about the water hiding in the plumbing.

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.
