Why Your Fireplace Smells And How To Tell If Your Chimney Is Blocked

| | ,

Wondering why your fireplace smells?

There are many different reasons your indoor fireplace is smelling out your house or allowing smoke into the room. I have a freestanding woodfire stove in my home and I always know when it’s time to sweep the chimney because it will release smoke into the room when lighting or adding wood.

That’s the number one reason a fireplace is putting smoke into a room – the chimney needs to be swept. However, there are many more reasons why your fireplace smells that we’ll get into below.

Fireplace Smell

If I’ve heard it once, I’ve heard it 1000 times: ‘my house smells like a campfire.’

I can often tell if someone needs to sweep their woodfire chimney as soon as I walk into their home.

Smoke won’t draw up a chimney as it should if it isn’t frequently cleaned. Instead, smoke will come out of the fireplace door when you’re lighting the fire or putting more wood on.

If you continue to use a fire that needs its chimney sweep, it will result in a smokey smell in a home. It seeps into the furniture, curtains, clothing, and even the carpets. It can also be a fire danger.

If you have a woodfire stove or fireplace and want a house that smells amazing, make sure you regularly clean your chimney, firebox, and the glass.

Why Does My Open Fire Smell?

Open fires can smell in the summer due to a downdraft from outside into the home.

This will bring the odor of creosote into your home. Creosote is the black stuff that you come across when cleaning your chimney. I find it tends to stick around the chimney cap in particular, but it lines the entire flue or chimney of your fireplace.

The best way to stop your open fire smelling is to apply a plywood cover inside your fireplace which will prevent any backdraft into the home. You can usually do this in such a way that it is not visible from the room (without bending over and looking up the fire).

Generally speaking, closed fireplaces don’t smell for this reason, unless they cannot be shut tight. If the seal on your fireplace door was not tight, it could become a problem.

How Often Should I Get My Chimney Swept?

How Can You Tell If A Chimney Needs Swept

How often you sweep your chimney will depend on the type of wood you are burning and how often it is lit, but at least twice a year is a good rule of thumb.

A fireplace and chimney that is drawing well will keep the smoke out of your home, which is better for your health and keeps things smelling nice!

If you are not burning seasoned wood (wood that does not have a high moisture content), you will need to clean your chimney more frequently. Also, if you have your fire going all the time, or if you keep it burning slowly all night, you may need to sweep your chimney more often.

If you have a small wood stove, like one of the Dwarf Mini Stoves, for example, you may need to sweep the chimney more frequently as they have smaller 3″ stove pipes.

How Can You Tell If A Chimney Needs Sweeping?

Here are 5 ways to tell if you need to sweep your chimney:

  1. Smoke comes out the door, rather than going up the chimney, when lighting the fire or putting more wood on
  2. It’s difficult to light the fire and keep it going
  3. Your fire isn’t putting out as much heat
  4. Excess soot and creosote is coming down into your fireplace
  5. You see signs that birds have built a nest in your chimney

I have seen some wood fire stoves that have basically become completely blocked. These fireplaces were filling the room with smoke before their owners decided to do something about it!

What Happens If Chimney Not Swept?

If you don’t clean your chimney at least once or twice a year, creosote and soot will continue to build up until it does become blocked. More seriously, you will stand a higher chance of having a chimney fire. If you burn your fire hot there will be less creosote build-up.

Many insurance companies require you to regularly sweep your chimney in order to remain covered for damage caused by a chimney fire and other fireplace-related house damage.

And, as we’ve already covered, if you don’t sweep your chimney, your house will begin to smell more and the inhabitants will be in a health-risk situation.

Why Does My Fireplace Smell Up The House?

I’ve touched on most of the reasons why fireplaces and wood stoves smell, but here is a summary.

A fire smells out a house because:

  • The chimney or flue needs swept
  • The firebox needs to be cleaned
  • There is a draft coming down the chimney
  • Your fireplace does not shut airtight
  • You are burning something you shouldn’t be (like treated wood)

It may also be because of a bad fireplace design.

Make sure you get one of the best wood stoves to ensure a quality design that doesn’t play up with these types of hassles.

How Do I Stop My Chimney From Smelling?

This will depend on what’s causing the smell – it’s important to identify that first!

  • Cleaning your chimney (call in a pro if you have any doubts)
  • Cleaning out all the ash and soot in the tray
  • Closing up the chimney so there’s no draft

Does Fireplace Make House Smell Like Smoke?

If there’s no other source of smoke in your home, then it’s your fireplace (unless your neighbor has their fire pit going)!

Most likely, you just need to sweep your chimney which will allow smoke to go up instead of into your living area. A smokey house is a horrible environment to be in, so don’t delay, and even cease lighting the fire until you’ve had it done.

How Do I Get Rid Of Fireplace Smoke Smell In My House?

After cleaning out your fire, it’s important to give your house a good airing out.

On a fine day, open up all the doors and windows for a number of hours, and even repeat this on a number of occasions. If things got really stinky, you might consider having your curtains cleaned (and other areas that are often missed in cleaning) as these can harbor a lot of those smokey smells.

Many people use essential oils and diffusers to help remove the smell of smoke from their homes. Reed diffusers are another popular way to have your home smelling nice again. Others use bowls of activated charcoal to help absorb smoke odors.

How Long Does Smoke Smell Last In House?

The smoke smell will eventually disappear once you start airing out your home – providing you’ve cleaned the chimney!

I’ve found it doesn’t take longer than 3 or 4 good air-outs to basically remove all the fire odors. However, it’s always going to depend on your particular situation – how much was going into the room and for how long, you know?

What Absorbs The Smell Of Smoke?

Here are some products or methods you can use to absorb the smell of smoke:

  • Leave bowls of activated charcoal or fireplace ash around your home
  • Purchases an ecologically friendly deodorizer
  • Use an air purifier
  • Wipe walls and surfaces with vinegar
  • Sprinkle baking soda on the carpets and vacuum

But ultimately, the method of removing smoke smell from a home that I’ve found most effective is simply airing it out.

Can You Get Carbon Monoxide Poisoning From A Wood Fireplace?

Yes, you can get carbon monoxide poisoning from a fireplace, that’s why it’s so important to keep your fire and flue/chimney clean.

A carbon monoxide detector and an alarm is also a good idea for those using wood fire or gas heating in their homes.

Why Does My House Smell Like Smoke Without Fire?

Here are some reasons your house smells like smoke without a fireplace:

  • You have a teenager secretly smoking cigarettes in their bedroom
  • There’s smoke coming in through an open window
  • Something is on fire in your house (stop Googling!)
  • An electronic device is faulty and causing burning smells
  • You have a rare syndrome called Kapnosis (from the Greek word for smoke) that causes you to smell smoke although there is no smoke

If you cannot find the source of smoke in your home, don’t delay and call the fire department. Better safe than sorry.

  1. I had a chimney fire in my home years ago – someone driving past came and knocked on my door and told me the roof was on fire. Nearly sh*t myself! Fire department had it put out in no time and there wasn’t a lot of damage done. Thankful for the passer by telling us about it or it could have been burning a lot longer before we realized.
