Pompano Beach · Chimney GuideIt happens two or three times a winter: a front clears the humidity, the evening breeze turns sharp, and suddenly every fireplace in north Broward gets remembered at once. Firewood bundles vanish from the grocery stores. Before you join the rush, spend twenty minutes on the fireplace that has been sitting untouched since February. It will repay you.
Between your last fire and this one, the flue has spent most of a year breathing warm, salty, humid air. Old soot absorbs that moisture and hardens into a crust. Metal parts, the damper especially, develop corrosion that can freeze the mechanism half-open or half-shut. Summer storms push leaves, palm litter, and grit past any gap in the cap, and nesting season may have added a tenant you have not met yet. None of it announces itself until you strike a match.
The riskiest opening move is lighting a full fire on faith. A flue with anything lodged in it sends smoke into the room within seconds, and a hidden nest above the smoke shelf can ignite. These are not rare, theoretical events; they are the standard cold-snap service calls every January in Broward County. Twenty minutes of checking, or a pre-season sweep booked back in the fall, is what separates a good fire night from an evening of airing out the house.
Start outside. From the yard, confirm the cap is present, sitting straight, and not visibly rusted through; binoculars help. Inside, open the damper and run it through its full travel a few times. It should move smoothly and seat firmly. With the damper open, shine a strong flashlight up past the smoke shelf and look for daylight, obstructions, or dangling debris. Sniff, too: a sharp animal or ammonia odor is a stop sign, not a quirk. Anything that looks or smells wrong means pause and get it checked.
Then run a draft test before committing real wood. Light a single sheet of rolled newspaper and hold it near the open damper. The smoke should pull upward decisively within a few seconds as the flue warms. If it drifts, stalls, or curls back into the room, the chimney is telling you it cannot move air right now, whether because of blockage, a stuck damper, or pressure conditions in the house, and a full fire will behave the same way, only bigger.
Our cold snaps call for small, hot, short fires, not the roaring all-nighters of northern winters. Dry wood is the whole game: buy it early, store it off the ground and under cover, and give grocery-store bundles a few days somewhere dry indoors before burning, since they often sit in open-air racks soaking up coastal humidity. A compact fire of genuinely dry wood burns clean, drafts hard, and leaves minimal residue in the flue. A smoldering heap of damp firewood does the opposite on every count.
Modern South Florida houses are sealed tight for air conditioning, and a tight house can starve a fireplace of makeup air. The fire wants to pull air up the flue, and the house has none to spare. If your fire seems sluggish or the room gets smoky despite a clear flue, crack a window an inch on the windward side and watch the draft straighten out. It is a small trick that resolves a large share of first-fire complaints in newer and remodeled homes.
When the warm weather returns, usually within seventy-two hours, close the damper completely once the ashes are stone cold. An open damper in this climate is a hole in your air conditioning envelope for the next ten months, quietly leaking cooled air and inviting humidity, odors, and wildlife. Scoop the cold ash, but leave a thin layer if you expect another front; it insulates the next fire's coal bed. Then the fireplace goes back to sleep properly instead of by neglect.
Finally, note anything the fires revealed. A damper that fought you, smoke that hesitated, an odor that lingered, stains that appeared above the mantel: each is easier and cheaper to address in the off-season than during the next December rush. If your opening fire of the season turned up any of them, call us while it is fresh. A free written quote now beats a cold living room when the next front is already on the radar.

Usually a blocked flue, a half-open damper, or a tightly sealed house starving the draft. Stop burning, let it die down, and have the flue checked before trying again.
It works if it is dry. Bundles often sit outdoors at the store absorbing humidity, so buy ahead and keep them somewhere dry for a few days before burning. Damp wood means smoke, weak fires, and extra flue residue.
Yes, fully closed once the ashes are cold. An open damper leaks conditioned air all summer and gives odors and wildlife a route inside. If yours will not seat properly, that is a repair worth making.
