As the air turns crisp and heating season begins, your fireplace becomes more than décor — it’s a primary comfort source.
Before lighting the first fire, take ten minutes to make sure your system is safe, clean, and efficient.
This quick checklist from Pure Flame Co walks you through everything to inspect, clean, and prepare so your fireplace performs beautifully all winter long.
Routine maintenance isn’t just about appearances — it directly affects safety, energy efficiency, and indoor air quality.
Neglected fireplaces can lead to:
A 10-minute pre-season inspection can save you hours of frustration later. For most homeowners, it’s the difference between a cozy winter and one full of drafts or odors.
Each step below can be done in under a minute. Together, they ensure your system is sealed, clean, and ready for the season.
Walk outside and look for cracks, leaning, missing mortar, or rusted flashing.
Why it matters: Damaged masonry or flashing lets water seep in and freeze, expanding cracks and weakening the structure.
Make sure your cap is secure and the screen is free of leaves or bird nests.
Why it matters: Caps prevent rain, debris, and small animals from entering the flue. A blocked screen can cause smoke backdraft.
Open and close the damper fully; it should move freely and seal tightly. Shine a flashlight up the flue for any soot or spider webs.
Why it matters: Sticky dampers or debris block exhaust flow and cause smoky fires.
Light a rolled piece of paper inside the firebox and observe the smoke. It should rise quickly up the flue.
If it lingers or drifts forward: The flue is cold or blocked — preheat it with a small kindling fire.
Remove leftover ash, soot, and debris. Check the grate for warping.
Why it matters: Too much ash restricts airflow and dulls combustion. Leave a thin 1-inch layer for insulation if you burn wood.

Inspect the glass for cracks or soot buildup and confirm that gaskets still form a seal.
Why it matters: Damaged seals leak air, reducing efficiency and drawing smoke into your room.

If you own a gas fireplace, check connections for leaks by applying a soap-and-water solution to joints while the line is on (bubbles = leak).
Why it matters: Even minor leaks increase risk of carbon monoxide buildup.
Test both alarms and replace batteries annually.
Why it matters: They are your first defense against invisible combustion gases.
For wood units, stock seasoned hardwood at 15–20% moisture content.
For gas units, ensure lines and valves are accessible.
For electric models, inspect cords and outlets.
If you haven’t had one this year, book a certified technician for a Level 2 chimney inspection before lighting your first major fire.
Why it matters: Professionals can identify liner cracks, soot accumulation, and venting issues that homeowners can’t see.

A quick pre-winter check now means less troubleshooting when temperatures drop — and no smoky surprises on the first cold night.
You should schedule a professional service if:
Certified sweeps use cameras to check liners, test dampers, and measure CO output — things DIY inspections can’t catch.
