Flames belong in your fireplace—not your chimney
Creosote buildup is the leading cause of chimney fires, as this tar-like substance sticks to your chimney walls and ignites when temperatures rise inside.
Expect to pay $500 to $2,500 for tuckpointing and $2,000 to $10,000 for chimney removal, so addressing fire risks early helps avoid costly repairs.
Your chimney flue can catch fire when leaves, branches, or animals block the passage and trap heat, creating dangerous conditions inside your home.
Hiring a local chimney repair professional provides reliable support with creosote removal and flue cleaning, keeping your fireplace safe to use all season long.
Even though chimneys are designed to withstand heat and flames, they can actually catch fire themselves—and put you in a life-threatening situation. So, what causes chimney fires? Often, it’s a buildup of creosote, but they can start for other reasons, too. Here’s how to prevent those problems so that your chimney doesn’t go up in flames.
Creosote, a tar-like byproduct of wood combustion, is the leading cause of chimney fires. While you burn wood in your fireplace, creosote sticks to the walls of your chimney. If you don’t clean your chimney often enough, the creosote can ignite when the temperature inside your chimney rises.
You can’t prevent a wood-burning fireplace from producing creosote, but you can—and absolutely should—hire a pro to regularly clean the buildup from your chimney.
It’s safest to hire a professional for any type of chimney work, but if you want to remove creosote from your chimney on your own, you have two options:
For light creosote buildup, you can use a chimney brush to scrub the residue from the inside of your chimney.
For moderate creosote buildup, you can apply a chemical creosote remover first, then brush the chimney.
Your chimney flue is the pipe that runs up your chimney and channels smoke and gas out of your home safely. If the flue gets blocked—often with creosote, leaves, branches, or animals—it can lead to a fire inside your chimney.
Again, we recommend hiring a pro for this sort of job—especially if the flue blockage is near the top of your chimney. If that’s the case, you’d have to climb onto your roof to clear it.
If you’re comfortable with that, you can follow these steps to clear a blocked flue:
Put on a protective face mask and safety glasses.
Empty your fireplace.
Cover your floors and nearby furniture with drop cloths.
If the blockage is near the base of your chimney, open the chimney damper and dislodge the debris with a chimney brush. When you finish, close the damper and clean up the mess with a shop vac.
If you’re clearing a clog at the top of your chimney, close the fireplace entrance with a plastic sheet and duct tape. Then, follow the rest of the steps.
Use a ladder to access your roof, being sure to follow ladder safety guidelines.
Remove the chimney cap.
Use a wire chimney brush to push the blockage down your chimney.
Replace the chimney cap.
Use a shop vac to clean up the debris.
As we’ve mentioned, it’s safest to have a professional address these kinds of chimney problems. There are a number of reasons for this, including the health risks of working with creosote and the potential dangers of climbing onto your roof. Plus, if you don’t know what you’re doing, you could accidentally damage your chimney while trying to fix it. For those reasons, we recommend hiring a chimney repair pro near you in situations like these.
Leave all chimney work to a pro. Chimney jobs involve working on a roof, potential exposure to creosote, and ensuring a safe repair or installation of chimney parts. Each of these can be seriously harmful or even deadly for anyone without expertise.
By following some basic fireplace maintenance tips, you can reduce the risk of a chimney fire at your home. These include:
Minimize creosote buildup: There are several ways to keep creosote buildup to a minimum, including using the right type of firewood and maintaining adequate airflow in your chimney.
Install a chimney cap: A chimney cap can prevent leaves, branches, and critters from going down your chimney and starting a fire. Plus, it can keep embers from flying out of your chimney and onto your roof, where they could ignite a fire.
Schedule annual chimney inspections: During a chimney inspection, a professional will thoroughly examine each part of your fireplace and chimney to make sure everything is in good condition and safe to use.
