7 Causes of Burning Smell From Fireplace

A burning smell coming from your fireplace can be alarming, especially when you're unsure of its cause. While fireplaces are designed to handle flames, they shouldn’t emit any strange or persistent odors.

Understanding the reasons behind this issue is crucial for both safety and comfort. In this blog post, we'll explore the common causes of burning smells from fireplaces and offer solutions to address them.

1. Creosote Buildup

Creosote is a byproduct of burning wood that accumulates inside your chimney over time. When it thickens, it can produce a strong, smoky odor, especially when the fireplace is in use. Excessive creosote can also pose a fire hazard, so regular chimney cleaning is essential.

Solution: Have your chimney inspected and cleaned by a professional at least once a year, or more frequently if you use your fireplace often.

2. Animal Nesting

Small animals, like birds, squirrels, or raccoons, sometimes seek shelter in chimneys. If they build nests or get trapped, the result can be a foul, burning odor when you light your fireplace.

Solution: Install a chimney cap to prevent animals from entering, and have any nests removed by a professional.

3. Damp Wood

Burning wood that hasn't been properly seasoned can produce an unpleasant smell. Wet or green wood doesn’t burn efficiently, leading to excessive smoke and a musty odor.

Solution: Always use dry, seasoned wood. Store firewood in a dry, well-ventilated area to ensure it’s ready to burn.

4. Blocked Chimney

A blocked chimney prevents smoke from escaping, causing it to back up into your home and create a burning smell and taping sound in chimney. Blockages can result from creosote buildup, debris, or animal nests.

Solution: Regular chimney inspections can catch blockages early. If you notice smoke backing up, discontinue use and call a chimney sweep immediately.

5. Dust and Debris

When you first light your fireplace after a long period of inactivity, accumulated dust and debris can burn off, producing a distinct burning smell. This is usually harmless and temporary.

Solution: Keep your fireplace clean, especially before the start of the heating season. If the smell persists, consider having it checked by a professional.

6. Electrical Issues

If your fireplace has an electrical component, such as an electric blower or a gas ignition system, a burning smell could indicate an electrical problem. Worn-out wiring or components can overheat and emit a burning odor.

Solution: Turn off the fireplace and have it inspected by a certified technician. Do not attempt to fix electrical issues on your own.

7. Foreign Objects

Sometimes, foreign objects like plastic, paper, or other non-combustible materials can accidentally end up in the fireplace. When these burn, they emit a harsh, acrid odor.

Solution: Ensure that only wood and approved materials are burned in your fireplace. Remove any foreign objects before lighting a fire.

FAQs

Q1: How often should I have my chimney cleaned?

A: It's recommended to have your chimney cleaned at least once a year, especially before the start of the winter season. If you use your fireplace frequently, you might need more frequent cleanings.

Q2: Can I use any wood in my fireplace?

A: No, only burn dry, seasoned hardwood. Softwoods and green wood produce more creosote and smoke, leading to odors and potential chimney issues.

Q3: What should I do if I smell something burning but can't find the source?

A: If you can’t identify the source of the burning smell, discontinue use of the fireplace and contact a professional. It’s better to err on the side of caution to prevent any potential hazards.

Q4: Is it normal for a new fireplace to smell?

A: Yes, new fireplaces may emit a slight odor when first used, as any residual oils or coatings burn off. This should dissipate after a few uses. If the smell persists, have it inspected.

Q5: Can I clean the chimney myself?

A: While some basic maintenance can be done yourself, such as removing ash or checking for obstructions, chimney cleaning is best left to professionals due to the tools and expertise required.

Conclusion

A burning smell from your fireplace is not something to ignore. By understanding the possible causes and taking appropriate action, you can enjoy your fireplace safely and without worry. Regular maintenance, proper use of materials, and professional inspections are key to keeping your fireplace in top condition. If you ever have concerns, don’t hesitate to reach out to a certified chimney sweep or technician for advice.
