As North Texas braces for a blast of winter weather, many homeowners are dusting off space heaters, checking weather apps, and asking a very old-fashioned question: Should I have my chimney swept before the cold hits?
The short answer is yes, if you plan to use your fireplace, and no, if you are not going to light it at all. The longer answer depends on safety, timing, and how North Texans actually use fireplaces during rare cold snaps.
Why chimneys matter during winter weather
When temperatures plunge, fireplaces suddenly go from decorative to functional. That quick switch is where problems can start.
Over time, chimneys collect creosote, a flammable byproduct of burning wood. They can also become blocked by debris, nesting animals, or damaged flue liners. When a fireplace is used after months or years of inactivity, those issues can turn a cozy fire into a fire hazard or a carbon monoxide risk.
According to fire safety experts, chimney fires often happen during the first few uses of the season, not after weeks of steady burning. That makes cold snaps especially risky for homes that rarely use their fireplaces.
The case for sweeping before a freeze
If you are planning to use your fireplace as a heat source or even just for comfort, having it inspected and cleaned ahead of time is widely considered a smart move.
A professional sweep can:
Remove creosote buildup that can ignite
Check for blockages that prevent smoke from venting properly
Inspect the flue and firebox for cracks or damage
Reduce the risk of smoke or carbon monoxide backing into the home
Fire departments routinely warn that improper fireplace use spikes during cold weather, especially in regions like North Texas where fireplaces are used infrequently.
The case against it, at least right now
There is one major downside: timing.
When winter weather is imminent, chimney services often book up fast. Last-minute calls can be expensive, and in some cases, crews may not be able to respond until after the cold has passed. That makes a pre-storm sweep unrealistic for many households.
There is also a practical reality in North Texas. Many homes have fireplaces that are more aesthetic than functional, and some residents never plan to light them, even during freezes. In those cases, a sweep ahead of a single cold weekend may not be necessary.
What matters more than the sweep
If you cannot get your chimney inspected before the cold arrives, safety officials say the safest option is not to use it.
Instead:
Use central heating systems as designed
Avoid indoor use of grills or propane heaters
Never burn wood in a fireplace with a closed or blocked flue
Install and test carbon monoxide detectors, especially near sleeping areas
Carbon monoxide risks increase during winter storms when homes are sealed tightly and alternative heat sources are used improperly.
So, is it wise or not?
If you regularly use your fireplace or plan to rely on it during cold weather, a chimney sweep is wise and recommended, ideally done before winter begins.
If you rarely use your fireplace and are scrambling because a freeze is days away, lighting it without inspection is riskier than skipping it altogether.
Bottom line
In North Texas, chimneys tend to be out of sight and out of mind, until winter weather forces them back into the conversation. A clean, inspected chimney can provide safe comfort during a freeze. An unchecked one can introduce fire and carbon monoxide dangers at the worst possible time.
As with many cold-weather decisions, planning ahead is the difference between peace of mind and a preventable emergency.
