Holy Smoke! My Fireplace is Smoking!

It’s one of those nice cool evenings when you just want to sit back and enjoy the warmth of your fireplace. You gather up the wood and get the fire started, but just as you’re getting comfortable a waft of smoke floats by your nose, and then more and more smoke is building up in your home. That definitely is not a good sign. Something is preventing your draft from working properly and smoke is escaping your fireplace.

If you notice smoke thickening in your fireplace and slowly spreading throughout your home, that’s not normal! Have it inspected to know what’s causing it.

Of course smoke should go up the chimney, not into the living area. That’s the very purpose of the chimney, to allow the harmful gases from combustion to exit the house not dwell in it. As you might have already figured out, your smoky fireplace might be an indication of an underlying problem.

Possible Causes

Moist Wood

The first thing that you can do by yourself is to check the kind of wood you are burning. Certain types of wood just naturally produce more smoke – the more moisture the wood contains, the more smoke (and production of creosote). That is why a drying process is necessary before using any kind of wood to burn in your fireplace.

Chimney Problems

Other more critical issues that could cause a smoking fireplace are chimney related, particularly pointing to the airflow, or the lack of it. When proper airflow is impaired smoke easily flows back into the house causing a lot of problems for homeowners, ranging from discolored furniture to severe health risks. That’s why you always want to make sure your fireplace and chimney are well-kept by having them inspected annually.

The most common impediment to proper chimney function is the presence of obstructions within the flue. These can come in the form of creosote buildup, dead leaves, and unusually, small animals. Creosote buildup is an inevitable occurrence with chimneys that are frequently used. Creosote is a normal byproduct of burning wood and over time it mounts up on the walls of the flue, narrowing the passageway of smoke as it tries to get out. This is the very reason why a regular chimney sweeping should be done because creosote is also very flammable and might even cause an unnecessary chimney fire. As for leaves and animals, having a chimney cap or crown installed will help you solve your troubles as it provides a barrier against these unwanted visitors inside your chimney. These accessories also hit two birds with one stone by complimenting the waterproofing of your chimney as well.

If you have a chimney damper installed, also make sure that it is still functioning properly. Otherwise, replace it because if it is always closed or will not open anymore, it defeats its purpose of controlling the amount of air flowing down to the fireplace. Instead it will be a trap for the rising smoke, which will have nowhere else to go but back down into the fireplace.

Let’s Keep That Chimney Clear!

Make sure your chimney flue looks like this. There should be no blockages of any sort.

For your chimney to function at its highest levels of efficiency and performance — sending heat and byproducts up and into the outside air — there needs to be a clean, unobstructed and uncompromised flue. Cracks and gaps will harm your draft, keeping the air from flowing the way it should. And blockages will, as that word implies, block the air from flowing, partially or completely, trapping heat and dangerous byproducts, and likely sending smoke and harmful gases billowing into your home.

A blocked flue is dangerous on several fronts — it can adversely affect the air inside your home, even lead to chimney fires. If you see smoke in your living area, notice a musty or smoky smell around your fireplace or find that dark stains are showing up around your appliance or chimney, you may have some flue blockage. It might be that you’re just overdue for a chimney sweeping appointment, or there might be other issues at work.

If you notice a problem, give Chief Chimney Services a call — our experienced technicians can find, remove and repair any issues related to chimney blockage. In the meantime, here are a few common contributors to a blocked chimney:

Creosote

When you use your wood-burning fireplace or stove, creosote is a natural result — it’s a deposit that builds up over time, as particulates and hot gases rise in your flue, hit the cooler flue walls and condense. Chimney professionals recommend regular chimney sweeping appointments because creosote deposits lead to a number of different problems and worries. If deposits are thick enough, they can block your flue, impeding the draft and letting toxic carbon monoxide get into the air you’re breathing. Since creosote is highly flammable, heavy creosote deposits can also become a serious fire hazard. And if creosote develops into third stage “glazed creosote” (often due to repeatedly burning wood with a higher moisture content), you’ll end up with higher chances of a chimney fire and a really difficult removal process.

Following proper burning practices (keeping your flue wide open during fires, using only seasoned cordwood, having your chimney regularly swept) can minimize creosote, and keep your chimney air flowing freely.

Animal And Plant Debris

If your flue isn’t topped with a chimney cap, you have a couple of big worries: things falling into your flue, and things climbing into your flue. An open flue makes it easier for branches, leaves and twigs to fall into your chimney, creating piles of highly flammable debris that impacts your draft and can become a fire hazard. But haphazard debris definitely isn’t your biggest issue — animals are drawn to the warm, confined safety of a chimney, so without a cap, you’re inviting anything from birds to squirrels and raccoons to move right in. Those new roommates bring in debris and create nests that can block your flue. They also tow in sounds, smells and bugs that you don’t want in your chimney, either. The best way to avoid all that: Make sure you have a correctly sized, correctly installed chimney cap on your system.

Broken Flue Tile Or Masonry Pieces

Many older chimneys were built and installed with terra cotta clay tile flue liners. And while those liners can hold up well with diligent maintenance, it’s not uncommon for tiles to crack or break, and for pieces to then fall into the flue. That leaves your chimney less protected, less efficient and potentially blocked up, too. Pieces of brick and mortar can crack and fall into the flue, too, bringing similar issues.

If damaged masonry pieces are blocking your flue, Chief Chimney can make the necessary repairs to clear out the flue and make the chimney whole again.

Regardless of what’s doing the blocking, a blocked flue makes for a much less efficient, much less effective and much less safe chimney. If you have any questions about blockages — or want to have our experienced technicians take a look at your system — just give Chief Chimney Services a call. We’re always here to help!
