Heating season is a few weeks out for most of the country, and the fireplace has spent six months as a decorative hole in the wall.
Below: the twenty-minute pass before you light anything, what to look at from the sidewalk, the houseplants that need to come in this week, and how to tell seasoned firewood from an expensive mistake.
Reply and tell us: do you actually use your fireplace, or is it furniture? We read every one.
Four Checks Before the First Fire

Nobody inspects a fireplace in July. So the first fire of the year usually goes into a flue that nobody has looked at since spring, and that's where the smoke-in-the-living-room stories come from.
The pass takes about twenty minutes. Do it in daylight, with a flashlight and a pair of gloves.
Open the damper and look up. Work it fully open and fully closed a couple of times, then shine the flashlight up the throat. You're looking for a nest, a pile of leaves, or anything blocking the view of daylight.
Look at what's coating the walls. The Chimney Safety Institute of America puts the sweep threshold at one eighth of an inch of sooty buildup. Flaky soot you can scrape off is normal at that depth. Shiny black tar is not, and it's the kind that burns.
Clear out the old ash. It goes into a metal can with a metal lid, and the can goes outside onto something that won't burn, well away from the house. Ash holds live embers for days.
Prime the flue before you light the fire. Roll up a sheet of newspaper, light one end, and hold it up inside the throat for a minute. That warms the column of cold air sitting in the chimney so it starts pulling upward instead of sitting on top of your kindling.
Step two is the one to take seriously. That shiny, glazed coating is hardened creosote, and CSIA's guidance is to stop and call a professional when you see it rather than sweep it yourself.
The standing rule behind all of this is NFPA 211, which CSIA quotes directly: chimneys, fireplaces and vents are to be inspected at least once a year for soundness, freedom from deposits and correct clearances. Once a year holds even for a chimney nobody used.
What to Check From the Sidewalk
Everything above happens inside. Five minutes outside is worth just as much, and almost nobody does it.
Stand back far enough to see the whole chimney. Binoculars help more than you'd think.
The cap. A missing or damaged one is how rain, leaves, squirrels and birds get in. Animal nests are part of why CSIA wants that annual look even on an unused chimney.
The crown. That's the concrete slab at the very top. Cracks in it let water into the masonry, and water is what takes chimneys apart.
The mortar joints near the top, for anything crumbling or missing.
Whatever is growing near it. A branch can reach across a flue in a single summer.
The stack itself, for any lean or bulge.
If you rent, none of this is yours to fix and all of it is worth putting in writing to your landlord in September rather than on the first cold night in December. A dated email is the entire point.
Nothing on that list is a job for you. The value is knowing before you light rather than after.
The Houseplants Have About Two Weeks Left

Anything that spent the summer on a porch or a balcony is on borrowed time now. Most common houseplants are tropical, and they stop being happy long before frost.
The working rule is to bring them in once nights start touching the low 50s, rather than waiting for a frost warning.
Don't just carry them through the door, though. A plant that has been outdoors all summer is carrying passengers.
Look under every leaf, and where each leaf meets the stem. Aphids, mealybugs, spider mites and scale all live in exactly those two places.
Hose the whole plant down outside, undersides included.
Soak the pot in a tub of water for about fifteen minutes to drive out whatever is living in the soil, then let it drain all the way.
Keep the new arrivals away from your existing indoor plants for two or three weeks. One infested pot will find every other pot in the house.
Then change how you treat them. Indoor light in October is a fraction of what a porch gets, so a plant that drank hard outside now needs far less water. Let the soil go dry an inch down before you water again.
Stop feeding them until spring as well. Growth is slowing down, and fertilizing a slow plant mostly builds up salt in the pot.
Expect some leaf drop for a couple of weeks either way. That's the plant shedding foliage it grew for brighter light, and it passes.
What Seasoned Firewood Actually Looks Like

Plenty of firewood sold as seasoned isn't, and wet wood is the reason a fire smokes, smells, throws little heat, and lays down the glazed creosote from the first section.
The target is one number. The EPA's Burn Wise guidance is that wood burns best at a moisture content below 20 percent, and that it needs to season for at least six months.
Four things tell you, without any equipment:
The cut ends are cracked. Dry wood splits outward from the center as it shrinks.
The bark is loose or has already fallen off.
It's lighter than it looks. Water is heavy, and a seasoned split feels surprisingly empty in the hand.
Two pieces knock rather than thud. Bang them together. Dry wood rings hollow, wet wood sounds dull and flat.
Storage is where most people undo the seasoning they paid for. The EPA is specific about it: keep wood outdoors, off the ground, with only the top covered, because covering the sides traps the moisture in.
A tarp wrapped around a whole pile is a greenhouse. Top on, sides open to the wind.
If you're buying this month, buy for next winter as well as this one. Wood bought green in September and stacked properly is what burns easily a year from now, and it costs less in the shoulder season than it will in January.
The Meter That Settles the Firewood Argument
Every check in the last section is a proxy for one reading, and the EPA's own advice is to test wood with a moisture meter before you burn it.
The one we'd point you to is the Firewood Moisture Meter from Northline Express, at $47.99, down from $59.99.
You push its two pins into a freshly split face, never the weathered outside, which reads dry no matter how wet the log is. It covers 3.0% to 40.0% at a stated accuracy of plus or minus 1%, which is far more resolution than a 20 percent decision needs. The display is backlit and gives you a bar graph alongside the number, and it ships with a padded case and a battery.
We haven't run this one through a season ourselves. The specs and the price come from the retailer's own listing.
$47.99 is more than this measurement has to cost. Plain pin-type wood moisture meters do the same job for less, and if you light three fires a winter, the four hand checks above will get you close enough. What the extra buys is a tool built and scaled for firewood rather than for lumber.
It's worth it if you burn regularly, buy by the cord, or have ever paid for seasoned wood and spent the winter regretting it. One rejected cord covers the cost.

What Never Goes in the Fire
One short list to finish on, because a fireplace is the one appliance people treat as a bin.
The EPA is blunt about what stays out of it:
Painted, coated or pressure-treated wood, plus plywood, particle board and anything with glue in it. All of them give off toxic fumes.
Ocean driftwood. The salt in it burns dirty and corrodes what it touches.
Wet, rotted, diseased or moldy wood.
Household trash, including cardboard, plastics, foam, and the colored ink on magazines, boxes and wrappers.
Plastic, rubber, and anything that used to be an animal.
What's left is one line: dry, split, well-seasoned firewood.
The two that catch people out are cardboard and wrapping paper, because both feel like they belong in there. Cardboard burns fast and sends large flaming pieces straight up the flue, and printed paper puts its ink into your air and your chimney on the way past.
One quick tap
Which should we cover next?
That's Friday: twenty minutes before the first fire, five minutes from the sidewalk, the plants that need to come in, and how to tell wood that's ready.
If you do one thing this weekend, open the damper and shine a light up there.
Forward this to whoever in your house is planning the first fire of the year.
Have a good weekend.
