Chimney Maintenance Tips for Big Bear’s Wood-Burning Homes

Owning a wood-burning fireplace in Big Bear means cozy nights, warmth during snowy winters, and a true mountain-living experience. But to keep your fireplace safe and efficient, your chimney requires regular attention—especially in a place with Big Bear’s unique weather conditions and heavy seasonal use.

Here are some essential chimney maintenance tips every Big Bear homeowner should know:

1. Annual Professional Sweeps & Inspections

A chimney should be swept at least once a year, ideally before the heating season begins in fall or winter. Professional sweeps remove soot, creosote, and debris that can block airflow and cause fires.

During an inspection, chimney experts check for:

• Damage to the flue and liner
• Chimney cap condition
• Cracks in masonry or mortar joints
• Signs of leaks or water damage

Don’t wait until the first cold snap—schedule your sweep early to avoid peak-season delays.

2. Use Dry, Well-Seasoned Wood

Burning wet or “green” wood creates excessive smoke and leads to faster creosote buildup inside the flue, which is a fire hazard.

• Hardwoods like oak and maple are better options because they burn longer, hotter, and cleaner than softwoods.
• Always store wood in a dry, covered place to keep it seasoned and ready for safe burning.

3. Check & Maintain the Chimney Cap and Crown

The chimney cap is your first line of defense against snow, rain, animals, and debris. A damaged or missing cap allows moisture to seep in, causing costly chimney deterioration.

The chimney crown—the sloped cement surface on top—should also be inspected for cracks. In Big Bear’s freeze-thaw cycles, even small cracks can expand into bigger problems.

4. Ensure the Damper Works Properly

The damper regulates airflow. Before lighting a fire, make sure it opens smoothly, and when your fireplace is not in use, close it to:

• Prevent drafts
• Keep warm air from escaping
• Maintain home energy efficiency

A tightly sealed damper can save you money on heating.

5. Watch for Smoke, Draft, & Creosote Signs

If smoke backs up into your living space, or if the draft feels weak, it may mean there’s a blockage or creosote buildup.

As a rule of thumb, if you see creosote thicker than 1/8 inch, it’s time for a sweep. Ignoring it increases the risk of a chimney fire.

6. Seal Up Cracks & Repair Masonry

Big Bear winters are tough on masonry. Snow and freezing temperatures can quickly worsen small cracks in:

• Bricks
• Mortar joints
• Flue linings

Repair damage promptly to avoid bigger structural issues. Consider waterproofing exposed masonry to protect against moisture penetration.

7. Keep Combustible Materials Away

Always use a fireplace screen or glass doors to keep embers from escaping. Store firewood and other combustibles well away from the hearth.

This simple step can prevent accidental fires.

8. Smoke & Carbon Monoxide Detector Safety

Every home with a fireplace should have working smoke alarms and carbon monoxide detectors, especially near sleeping areas. Blocked or inefficient chimneys can cause harmful gas buildup. Test detectors monthly and replace batteries regularly.

9. Seasonal Preparations & Off-Season Maintenance

After the heating season, inspect your chimney in spring for any damage or lingering moisture issues. During the off-season, keep your damper closed and consider chimney balloons or covers to prevent drafts, pests, and water entry.

10. Keep Records & Schedule Maintenance

Maintain a log of inspections, cleanings, and repairs. This not only helps with safety and insurance but also ensures you stay on top of maintenance.

Schedule ahead—before heavy snow and cold set in—to secure your spot with a professional chimney sweep.

Final Thoughts

In Big Bear, where winters are long and fireplaces are heavily used, chimney maintenance isn’t just recommended—it’s essential. By following these tips, you’ll protect your home, improve heating efficiency, and enjoy your fires with peace of mind all season long.
