Fireplace & Chimney Safety During a Winter Storm: What to Know Before the Freeze Hits
When a winter storm is in the forecast, many North Texas homeowners start thinking about staying warm—especially if power outages are a possibility. Fireplaces can be a great source of heat during cold weather, but only if they’re used safely and properly.
Before temperatures drop and the snow or ice arrives, it’s important to understand how winter storms can affect your fireplace and chimney—and what steps you should take to protect your home and family.
Why Winter Storms Increase Fireplace Risks
During freezing weather, fireplaces are often used more frequently and for longer periods of time. At the same time, winter storms can:
Restrict airflow in chimneys
Expose existing damage or blockages
Increase the risk of carbon monoxide buildup
Cause drafting problems due to temperature and pressure changes
If your fireplace or chimney hasn’t been inspected or maintained, these issues can become dangerous very quickly.
Power Outages and Fireplace Use
If you lose power during a winter storm, your fireplace may seem like an obvious solution—but not all fireplaces are safe to use without electricity.
Wood-burning fireplaces can typically be used during power outages, if the chimney is clear and functioning properly.
Gas fireplaces may require electricity to operate fans, ignition systems, or safety features.
Gas logs should never be used if the system is damaged, improperly vented, or not designed for continuous use.
If you’re unsure how your fireplace operates during a power outage, it’s best to find out before the storm hits.
Carbon Monoxide: A Serious Winter Risk
Carbon monoxide is one of the most dangerous risks associated with improper fireplace use—especially during storms.
Blocked chimneys, closed dampers, or damaged flue liners can cause smoke and gases to back up into your home instead of venting outside. Carbon monoxide is odorless and invisible, which makes it especially dangerous.
Make sure:
Your damper opens fully
Your chimney cap is intact
Carbon monoxide detectors are installed and working
If you ever feel dizzy, lightheaded, or notice unusual smoke behavior, stop using the fireplace immediately and ventilate the area.
Common Winter Storm Fireplace Problems
During extreme cold, homeowners often experience:
Smoke entering the room
Poor draft or downdrafts
Strange odors when the fireplace is in use
Excessive creosote buildup igniting due to extended burn times
These issues often point to maintenance or structural problems that shouldn’t be ignored.
What NOT to Do During a Freeze
During a winter storm:
❌ Do not burn wet or unseasoned wood
❌ Do not leave fires unattended
❌ Do not use outdoor fire pits or grills indoors
❌ Do not assume a rarely used fireplace is safe without inspection
Shortcuts during extreme cold can lead to costly—and dangerous—outcomes.
Why a Chimney Inspection Matters Before Severe Weather
A professional chimney inspection can identify:
Blockages from debris or animals
Cracked flue liners
Structural damage
Venting issues
Creosote buildup
Catching these issues before a winter storm helps ensure your fireplace operates safely when you need it most.
Stay Warm—And Safe—This Winter
Fireplaces can provide comfort and warmth during winter storms, but only when they’re properly maintained and used responsibly. A little preparation before the freeze can prevent emergencies when conditions are at their worst.
If you’re unsure whether your fireplace or chimney is safe to use during an upcoming winter storm, it’s better to have it checked than to take the risk.
