Is Your Chimney Ready for Santa? A Last-Minute Safety Checklist

We all know about Christmas. It comes at the same time every year. But still, it has a way of sneaking up on us. One minute you’re unpacking Halloween decorations and buying candy, the next, you’re scrambling to get your Christmas lists filled. We understand. Everyone is busy, and it’s easy to forget about the holidays and all the things you must do to get ready. And it’s even easier to forget about crucial maintenance tasks (like chimney chores) until it’s too late. If you’re planning to use your fireplace this holiday season, whether for warmth or the magical ambiance it brings to the room, a last-minute safety check can make the difference between wonderful holiday memories and a disaster.

Here’s a simple, effective checklist you can run through today to ensure your chimney is safe, clean, and ready to rock!

Make Sure the Chimney Gets a Professional Cleaning and Inspection

If you’ve not had your chimney cleaned and inspected yet this year by a certified professional, call now because this is your top priority. The National Fire Protection Association recommends a professional inspection at least once a year, even if you don’t use your chimney regularly. Regular use, especially if you’re burning wood, leads to creosote buildup, a highly flammable tar-like substance that can ignite even with a small spark. Also, animals may have nested in the flue during the summer, causing blockages that prevent proper venting. A certified chimney sweep can spot these issues quickly and clean the flue if needed.

If you’re down to the wire and can’t book a full inspection before guests arrive, schedule one for as soon as possible. Meanwhile, avoid using the fireplace until a pro gives you the green light.

Check the Firebox for Cracks, Damage, or Excess Ash

Before lighting a fire, look closely at the firebox inside and out. Look for:

• Hardened or crumbling ash
• Cracks in the mortar joints
• Metal components that look warped or rusted

A small amount of ash is fine, but a thick layer can restrict airflow. Remove the excess ash, leaving about an inch so it can help insulate the firebox floor. If you see cracks or loose bricks, don’t use the fireplace until repairs have been made because these can allow excess heat to escape into the surrounding walls, creating a fire hazard.

Confirm the Damper Opens and Closes Smoothly

The damper controls the airflow. If it’s stuck closed when you start a fire, smoke will billow into your home. If it’s stuck open after the fire, the warm air will escape up the chimney, forcing you to run the furnace more and driving up energy costs.

Before the holidays:

• Open the damper fully and make sure you can see daylight up through the flue.
• Close it again to ensure smooth motion.
• Remove debris that’s blocking movement.

If the mechanism is stiff or won’t fully open, get it repaired or replaced before using the fireplace.

Inspect the Chimney Exterior and Crown From the Ground

You don’t need to climb on the roof for this quick check. From the ground, look for:

• Cracked or missing bricks
• Crumbling mortar joints
• Leaning or obvious structural shifts
• Staining or discoloration, which could indicate that you have a moisture problem

You can use binoculars or your phone’s camera zoom to get a clear view of the crown. The crown is the top layer that seals the chimney. A damaged crown can allow water to seep in, leading to spalling bricks, internal deterioration, and even mold. If you notice exterior damage, don’t use the fireplace until a professional inspects it.

Make Sure the Cap is Secure

A chimney cap keeps animals, leaves, sparks, and rain out of the chimney. If the cap is missing or damaged, larger debris can enter the flue and ignite, or sparks can escape and land on the roof. From the ground, confirm that:

• The cap is present
• The mesh screen is intact
• Nothing seems tilted or broken

If you suspect it’s loose or missing, call a chimney technician to replace it as soon as possible.

Test the Smoke and Carbon Monoxide Detectors

Finally, if you have a working fireplace, whether wood-burning or gas, working smoke and carbon monoxide detectors are a must. The National Fire Protection Association says that an average of 1,450 deaths occur every year in homes with missing or non-functioning smoke alarms. Check the batteries in your detectors and replace them if needed.
