Your Local Fix for a Smoky Fireplace
Smoke comes into the room when the chimney cannot pull as hard as the house pushes back. The cause can be inside the chimney, such as a flue too small for the opening, or outside it, such as a top that sits too low or wind off a taller roof. Or the house itself, with fans running, pulls air down the flue. We test until we know which.
About Smoke & Draft Problems
Draft is a pressure difference. Hot flue gases are lighter than the air outside, so a column of them rises and pulls room air into the firebox behind it. A taller, warmer flue pulls harder. Smoke rolls into the room when something tips that balance: a flue too cold to start drawing, a flue too small for the opening, wind pressing on the chimney top, or the house itself pulling air in through the easiest path, which is often the fireplace.
Each of those causes is common in the region's housing. Brownstone and older rowhouse fireplaces were often enlarged or converted from coal and now feed flues that are too small for them. Exterior chimneys on colonials and capes start cold on winter evenings. Insulated, air-sealed homes with powerful kitchen hoods can outpull a chimney. Additions, dormers and taller houses next door change how wind flows over a roof and push it down short stacks.
Diagnosis comes before any repair. The pattern says a lot: smoke only at lighting points to a cold flue; smoke only in wind points to the top; smoke when the range hood runs points to house pressure. Testing with the flue warmed, and with doors, windows and fans in different positions, confirms it. The repair then targets the cause, starting with the simplest change that solves it.
What Our Crew Does
- A history of when the fireplace smokes, in what weather and with which fans running
- A blockage check of the cap, flue, smoke chamber and damper
- The opening measured and compared with the flue size
- Chimney height checked against the roof and nearby structures
- A draft test with the flue warmed and the house set up several ways
- The likely cause explained, with the simplest fix tried or proposed first
- Further work, if needed, priced in writing before it starts
When to Call Us
- Smoke spills from the top of the opening as soon as the fire is lit
- It only smokes on windy days
- It smokes when the kitchen fan or the dryer is running
- You smell smoke in an upstairs room while the fireplace burns
- Soot stains on the brick or mantel just above the opening
How the Job Goes
- Hear the pattern
We ask when it smokes: at lighting, all the time, in wind, or with fans running. The pattern points to the cause.
- Test the draft
With the flue warmed, we watch how smoke moves at the opening with doors, windows and fans in different positions.
- Check the build
Flue size against the opening, chimney height, the cap, the damper and any blockage are checked one by one.
- Fix the cause
We start with the simplest fix that answers the cause and give you a free written estimate for anything beyond that.
Your Options
A metal or glass strip across the top of the opening that reduces its height, helping an oversized opening match its flue.
Masonry work that reduces the opening permanently when a smoke guard is not enough.
For chimneys that smoke mainly in wind, by adding height or shielding the flue top from gusts.
An electric fan mounted on the flue top that pulls exhaust up when natural draft cannot do it alone.
A dedicated source of combustion air so the house stops pulling air down the chimney.
What Affects the Cost
- What the testing shows the cause to be
- Metalwork for a smoke guard sized to the opening
- Masonry work to resize the firebox or extend the chimney
- Electrical work to power a chimney fan
- Safe access to the top for a cap, fan or extension
Every job starts with a free written estimate, so you know the price before we start.
When It Cannot Wait
- Smoke appearing in rooms on another floor, which can mean a crack in the flue
- Carbon monoxide detector sounding while the fire burns: leave and call 911
- Smoke seeping from walls, closets or around the chimney breast
- Heavy smoking that began right after a chimney fire
Make It Last
- Prime a cold flue by holding burning rolled newspaper up near the open damper for a moment
- Turn off range hoods and bath fans while the fire is getting started
- Burn small, hot fires of dry split wood rather than large smoldering loads
- Keep the cap screen clean so it does not choke the draft

Guides From Our Crew
Why Is My Fireplace Smoke Coming Into the House?Smoke rolls into the room when the chimney cannot carry it away as fast as the fire makes it.
Why Is My Chimney Not Drawing Smoke Up?A chimney draws because hot smoke weighs less than the cold air outside, so it rises and pulls room air in behind it.
What Causes a Chimney Downdraft?Downdraft is air flowing down the chimney instead of up.
Why Is My Chimney Smoking So Much?Heavy smoke from a chimney usually means the fire is not burning completely.
Chimney Fans for Fireplaces: When They HelpA chimney fan earns its place when a fireplace smokes because the chimney cannot make enough draft by itself: a short chimney, a taller building next door, or an opening too big for its flue.
Why Does My Neighbor's Chimney Smoke Get Into My House?Smoke from next door usually enters through your own chimney.
