Why did it only happen on the first cold night?

A cold flue draws badly until it warms up, and the colder the chimney, the longer that takes. If the flue is also partly blocked or the damper is not fully open, that slow start is enough to push smoke into the room. It is worth having it swept and inspected rather than waiting to see if it clears.

Does smoke in the room mean carbon monoxide?

If smoke is coming back, combustion gases are coming back with it, and carbon monoxide is among them. You cannot see or smell it. Put the fire out, open a window, and if anyone feels headachy or dizzy, get outside and call 911.

Do I need a permit for this in New York City?

Sweeping and inspection generally do not require one. Installing a stove or insert, relining a flue with an appliance, or rebuilding a chimney above the roofline usually does, and permits in the city come from the NYC Department of Buildings. Call them before work starts, since the city also restricts solid-fuel appliances.

Is there a state chimney sweep license in New York?

New York does not issue a statewide license for chimney sweeping, inspection or masonry repair. It is handled locally instead — New York City requires a Home Improvement Contractor license through the Department of Consumer and Worker Protection. Verify current requirements with the city or county licensing office where the work will be done.

Smoke in the room in New York, NY

You lit a fire and the smoke rolled out into the room instead of going up. That means the chimney is not pulling. Something is in the way, the damper is shut or stuck part way, or the flue simply is not drawing enough air. Whatever the cause, the smoke you can see is coming with combustion gases you cannot see, and carbon monoxide is one of them. Put the fire out, open a window, and stop using the fireplace until someone has looked up the flue. If anyone in the house feels headachy, dizzy or sick, get outside first and call 911.

This happens a lot in New York. A cold flue draws badly until it warms up, so the first fire of the season is often the one that backs up. The city's housing stock is largely pre-1940 brick and brownstone, and those old chimneys, liners and mortar joints are a constant maintenance item. Freeze-thaw cycles from roughly December through March crack crowns and open mortar joints, and debris from that damage can drop into the flue. Air matters too: a tightly sealed home or a powerful kitchen extractor fan can beat the chimney for air and pull the smoke back toward you.

While you wait — please don't

Do not light another fire. Until the flue has been checked, every fire puts smoke and carbon monoxide back into the room.
Get air moving, and get out if anyone feels unwell. Open a window and leave the room; headache, dizziness or nausea means go outside and call 911.
Turn off extractor and range fans. A strong fan in a tight house can pull harder than the chimney and drag smoke back into the room.
Do not force the damper or poke at a blockage. Forcing a seized damper or shoving something up the flue can jam it worse or bring debris down on you.

What the technician does

The flue is swept and camera-inspectedThe technician sweeps the flue and runs a camera up it to find the blockage or damage. Ask to see the footage yourself.
The damper is checkedA damper that is stuck, warped or only opening part way is a common reason smoke comes back. It is freed, repaired or replaced.
Draft is tested and the cause identifiedThe technician tests how the chimney is actually drawing and works out why it failed, rather than guessing at it.
Cap and crown are checkedA damaged cap lets debris and nests into the flue, and a cracked crown lets water into the masonry. Both get looked at from the top.
The smoke chamber is cleaned and pargedThe smoke chamber sits just above the firebox and guides smoke into the flue. Cleaning and parging it smooths the path so the chimney pulls properly.

Why this happens in New York, NY

New York's fireplaces are mostly old ones. Brick rowhouses, brownstones, masonry walk-ups and prewar apartment buildings make up much of the housing here, and many of those original fireplaces have been sealed over the years or converted to gas or to heating-flue use. Liners, parapets and mortar joints in that kind of building need regular attention. Working fireplaces with driveways and yards around them are concentrated in the outer boroughs — Bay Ridge, Forest Hills, Riverdale, St. George on Staten Island, eastern Queens — while a lot of Manhattan and dense Brooklyn and Queens buildings are co-ops and condos where a board has a say in what gets done.

Timing matters here as well. Demand climbs with the first hard freeze and the start of the heating season in late fall, then again after winter nor'easters, so the flue is worth booking before you need it. On permits and licensing, New York City enforces its own NYC Construction Codes and issues permits through the Department of Buildings, not a state agency. Routine sweeping and inspection generally do not need a permit; installing a wood stove or insert, relining a flue as part of an appliance installation, or rebuilding masonry above the roofline usually does. New York City also applies extra restrictions to solid-fuel appliances, so call the Department of Buildings before any work begins.
