Chimney Drafting Problems? A Chimney Pot Might Solve Them.

Chimney drafting repair in Amherst, NH

Does your fireplace periodically (or regularly) have drafting problems? Does smoke back up into the house when you’re burning a fire? Are your fires sluggish and never seem to get up and roar? A “yes” answer to any of these questions may point to a drafting issue. If this is the case, a chimney pot could be your solution.

What is a chimney pot?

Chimney pots are hollow cylinders that are attached to the top of chimneys to provide more draw for the air that circulates through the firebox and up the flue.

Most often made of clay, steel or copper, chimney pots can be round, square or some other shape, just as long as they’re hollow and are correctly fitted to the chimney top. Common installation methods include crown-mounted, flue-mounted and mortar-mounted.

There’s nothing high-tech about a chimney pot, but the effect it has on your fire-burning experience can be quite amazing.

Drafting physics

Without getting overly scientific, smoke combined with combustion gases is lighter than air, so it naturally rises into the air above it (i.e., goes up the chimney). Think of an outdoor fire: the smoke always goes up, never down. But, in a relatively enclosed space like a chimney flue, the smoke needs the assistance of air flow to move upwards efficiently.

When a fireplace and chimney are built, the chimney should be the correct diameter and height for the size of the fireplace. If the chimney is too short, drafting will be impeded because there isn’t enough air-draw.

Years ago, somebody figured out that the best way to solve this problem wasn’t to build on to the chimney or reduce the size of the fireplace, but rather to add a chimney extension.

The chimney pot made the perfect extension to give the flue the added height necessary to draw air and smoke efficiently. If your chimney draws sluggishly or inconsistently, a chimney pot may be the answer. Then again, it may not.

Chimney drafting repair in Concord, NH Other reasons for drafting issues

If a chimney pot doesn’t help, you’ll need to look at other reasons for a poorly drafting fireplace/chimney. These include:

Air-tight house:  Many newer homes, in the name of energy-efficiency, have been built pretty close to air-tight. This arrangement helps to keep outside air outside and inside air inside, but it can hamper chimney drafting. Chimneys rely on interior air to get the draft moving, and if there isn’t enough, smoke won’t rise as it should.

Obstructions in the flue:  A large buildup of soot and creosote as well as outside debris such as bird nests, leaves, twigs and air dust can create a flue obstruction and reduce drafting ability of the structure.

Damper issues:  Rusted or warped fireplace dampers may not open fully during a fire, which will impede air flow.



If you’re having problems with how your chimney is drafting smoke and the dangerous toxins it contains, rest assured that there is a solution.

I wanted to give 5 stars but they are very busy which meant I had a good wait for both the inspection/cleaning, then for a quote on repairs and then for the repairs. Their prices seemed a little high to me but I have nothing to compare with as they were highly recommended by someone I trust and other companies had plenty of negatives reviews which kept me from getting additional quotes. I am happy with the work and they promptly returned to fix a mistake that had been made. Chris the inspector, Jennifer in the office, and Alex and his repair crew were all pleasant and took the time to answer all of my questions. Alex and his crew even took their shoes off (it was winter) before entering my house without even being asked! So if you are not in a rush and want to ensure you chimney is as safe as possible then I think you'll be happy with Black Moose.

After a recent sweep of our chimney, it was discovered that our flue tiles were cracked. Black Moose techs were hard working, detail oriented and professional! Nice jobs guys! See you next year for my cleaning!

Excellent I highly recommend Black Moose Chimney and Stove; Kelly and Liam are awesome, they did a great job. Extremely professional, arrived early, went through everything with a fine tooth comb ensuring pellet stove was thoroughly cleaned. They also were respectful of my home, conscientious and cleaned up after themselves. Made sure stove worked prior to leaving and told me to call promptly if anything came up afterward. Will definitely use them again.

We've had Black Moose clean our chimney for a number of years.But recently, we had an emergency situation at our home involving our chimney & oil furnace flue, which was caked full of soot from a malfunctioning furnace. They came & cleaned out both flues in no time, even going up on the roof with snow on it! They cleaned up after their work in the interior rooms where the oil furnace and the woodstove are located. Great work. Reasonable prices. Very nice people. You can't go wrong with Black Moose.

Goods: The technicians know their business, very efficient in cleaning/inspection along with cleaning up after the 'dirty work'.Others: Communications could be more effective. Despite early coordination about scope of work (multiple flues within same chimney) the estimate provided did not reflect this and the final invoice was significantly more than the estimate provided.Quote for follow-on chimney relining was significantly more than that offered by other companies in the area (and far more than neighbors experienced for similar work accomplished by other companies)
