A smoking fireplace is not always a dirty fireplace. ABC Chimney Solutions evaluates the entire draft path, including the chimney height, flue condition, liner, cap, house pressure, appliance connections, nearby structures, terrain and wind exposure to determine why the system is not moving smoke the way it should.
The house can be part of the problem
A tightly sealed home or strong exhaust appliances can change the pressure around a fireplace. ABC Chimney Solutions can evaluate whether the building is short on replacement air or whether kitchen hoods, bathroom fans, HVAC or other systems are contributing to negative pressure when the fireplace is operating.
Terrain and wind matter
A home in a valley, on a hill or in an exposed wind pattern can experience draft behavior even when the chimney itself is generally well built. ABC Chimney Solutions can evaluate chimney height, wind interaction and the existing cap and may recommend a draft-assist or wind-resistant cap, a height change or another system-specific solution.
A practical starting tip
In a very tight house, slightly opening a nearby window or door while starting the fire can sometimes help establish the initial draft. Once the chimney is drawing steadily, the opening may no longer be needed. ABC Chimney Solutions treats this as a troubleshooting clue, not as a substitute for diagnosing a recurring draft problem.
Verify the result
When a draft repair can be tested with the operating system, ABC Chimney Solutions checks the system in use so the result is evaluated under real conditions rather than only on paper.
- Smoke rolling back
- Weak or reversing draft
- Heating venting checked

Draft & Smoke Problems — frequently asked
What homeowners ask ABC Chimney Solutions most often about draft & smoke problems.
Why does smoke come back into my house?
ABC Chimney Solutions checks for blockage, flue or liner damage, chimney height, cap problems, house pressure, terrain, wind and other conditions because smoke backup can have more than one cause. Learn more about this service.
Can a house be too airtight for a fireplace?
Yes. ABC Chimney Solutions can evaluate whether a very tight home or competing exhaust equipment is reducing the replacement air available to the fireplace and contributing to poor draft. Learn more about this service.
Can changing the chimney cap improve draft?
Sometimes. ABC Chimney Solutions may recommend a wind-resistant or draft-assist cap when the existing cap or local wind pattern is part of the downdraft problem, but the rest of the chimney is evaluated first. Learn more about this service.
Can you make a chimney taller to improve draft?
Yes, when additional height is the appropriate solution. ABC Chimney Solutions can extend masonry or approved venting systems based on the chimney configuration and project requirements. Learn more about this service.
What does ABC Chimney Solutions mean by the house can be part of the problem?

Why does my fireplace smoke only sometimes?
Intermittent smoking usually points at wind, terrain or air pressure in the house rather than the flue itself, because a blockage would cause it every time. ABC Chimney Solutions can tell you which applies to your chimney when it looks at draft & smoke problems. Learn more about this service.
How do you diagnose a draft problem?
By checking the things that actually govern draft: chimney height relative to the roof, flue size against the opening, the smoke chamber, blockages, and how much replacement air the house allows. ABC Chimney Solutions works to this on every draft & smoke problems job it takes on. Learn more about this service.
Does flue size matter that much?
It does. A flue too large for the opening never establishes a proper column of rising gas, and one too small cannot carry what the fire produces. ABC Chimney Solutions can tell you which applies to your chimney when it looks at draft & smoke problems. Learn more about this service.
Will adding height fix it?
Only where height was the cause. Adding height to a chimney whose problem is the smoke chamber or the flue size changes nothing, which is why the cause is established first. It is one of the things ABC Chimney Solutions assesses when it looks at draft & smoke problems. Learn more about this service.
What if two appliances share the chimney?
That can cause it, particularly where one was added later without the venting being reconsidered. It is one of the first things worth checking. This is part of what ABC Chimney Solutions checks before quoting draft & smoke problems. Learn more about this service.
Why does my fireplace smoke into the room?
Usually because the chimney is not drawing enough for the opening it serves. Chimney height, flue size, the smoke chamber, a blockage, or the air pressure in a tightly built house can each cause it, and ABC Chimney Solutions checks which before changing anything. Learn more about this service.
What is a downdraft?
Air coming down the chimney rather than up it. Terrain, nearby trees or roof shapes, and a stack that is short relative to the roof can all push a flue into downdraft in certain wind conditions, which is why it can be intermittent. It is one of the things ABC Chimney Solutions assesses when it looks at draft & smoke problems. Learn more about this service.

Reviews from the towns we work in
Eight of the several thousand chimneys we have swept, lined and rebuilt across Connecticut.
The inspection found a cracked clay liner two other companies had missed. Relined in stainless the following week and the smoke coming back into the room stopped dead.
Open fire had not been swept in six years. They pulled out a shocking amount of creosote, sheeted the whole hearth, and left the room spotless.
Damp was coming through the chimney breast for two winters. They traced it to a failed crown, recast it and waterproofed the brickwork — bone dry since.
Flashing had lifted and the damper had seized shut. Both repaired in one visit, and they showed me the before and after photos on the roof.

Full stack rebuild above the roofline on a 1920s house. They matched the original brick and mortar so closely the neighbors asked who did our repointing.
Booked the sweep on Monday, done Tuesday. The photographs and written flue report are more thorough than the survey we paid for when we bought the place.
Our wood stove never drew properly. They worked out the flue was oversized for the appliance, fitted an insulated liner, and it lights first time now.
Needed the chimney looked at fast for a house sale. On the roof the next morning, and I had a clear answer and a price the same afternoon.
