The short answer
Check Your Fireplace First
Before lighting any fire, inspect the fireplace and chimney. Look for cracks in the firebox, loose bricks, or damaged mortar. Check the damper opens and closes fully. Examine the exterior for rust or water stains, which can indicate leaks that weaken the structure.
Look up the chimney for blockages like bird nests or creosote buildup. Creosote is a flammable residue that can cause chimney fires. If you cannot see clearly, use a flashlight or mirror. Any sign of damage or blockage means you should not use the fireplace until a qualified professional inspects it.
- Cracks in the firebox or bricks
- Rust or water stains on the exterior
- Damper that sticks or does not seal
- Blockages like nests or creosote in the chimney
- Unusual odors when the fireplace is idle
Safety Steps for Each Fire
Always open the damper before starting a fire. Use seasoned, dry wood, not green or treated lumber. Build small fires that burn hot and clean. Keep a metal screen or glass door in place to stop sparks from escaping into the room.
Keep flammable items like furniture, rugs, and curtains at least three feet away. Place ashes in a metal container with a lid, and store it away from the house. Install and test smoke and carbon monoxide detectors monthly. These simple habits reduce most risks.
- Open the damper fully before lighting
- Use dry, seasoned wood only
- Keep a metal screen or glass door in place
- Maintain a three-foot clearance from flammables
- Store ashes in a covered metal container
- Test smoke and carbon monoxide detectors monthly
Know the Warning Signs
Certain symptoms mean your fireplace is not safe to use. A strong, smoky odor inside the home when the fireplace is cold can signal a draft problem or creosote buildup. Heavy soot around the firebox or on the mantel suggests incomplete combustion. Popping or cracking sounds beyond normal wood noises may indicate structural issues.
Water stains on the ceiling near the chimney or on the fireplace surround often point to a leaky roof or flashing. In wet climates, this is worth checking before the rainy season. If you see any of these signs, stop using the fireplace and call a professional for an inspection.

When to Call a Professional
Some issues require a trained eye. A chimney sweep or fireplace inspector can evaluate the flue, liner, and overall structure. They can remove creosote, repair mortar, or replace damaged parts. If you have any doubt about the condition, it is safer to ask for an inspection before lighting a fire.
Also, if your home has experienced water damage, the fireplace structure may be compromised. Moisture can weaken masonry and corrode metal components. A water damage inspection can identify hidden problems. Checking for water damage after wet seasons is a wise step.
What If Water Damage Is Involved
Water intrusion around a fireplace often goes unnoticed until it causes serious damage. Leaks from the roof, chimney flashing, or exterior walls can saturate the firebox and flue. This can lead to spalling brick, cracked mortar, and rusted dampers. Using a damaged fireplace increases the risk of fire or carbon monoxide leaks.
If you suspect water has affected your fireplace, do not use it. Instead, have a professional assess the extent of the moisture. Structural drying and dehumidification may be necessary to dry out the materials. Moisture mapping can help locate hidden damp spots. Addressing the water issue first ensures the fireplace is safe for future use.

How often should I have my fireplace inspected?
Most safety experts recommend an annual inspection before the heating season. If you use the fireplace frequently, a mid-season check is wise. If you notice any damage or unusual signs, schedule an inspection sooner.
Can I clean my chimney myself?
Cleaning a chimney requires proper tools and knowledge. You can remove light soot with a brush, but creosote buildup needs chemical cleaners or professional equipment. Incorrect cleaning can damage the liner. When in doubt, hire a chimney professional.
What should I do if I smell smoke inside the house?
Immediately extinguish the fire and open windows for ventilation. Do not relight the fireplace until you identify the cause. A smoky odor may indicate a blocked flue, a cracked liner, or a negative pressure issue. Call a professional for an inspection before using it again.
