Quick Answer
Okay, so here's the quick version. A proper chimney inspection is more than a quick peek. It's about safety. We're looking for creosote buildup, which is basically fuel for a chimney fire, and structural problems like cracked crowns or bad flashing that let water in. A basic visual inspection, what we call a Level 1, might run you $80 to $250, often with a cleaning. If you're buying a house, you need a Level 2 with a camera, maybe $250-$700. Don't skip it. A safe chimney is no accident, it's just good maintenance.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Perform a visual inspection from the ground. Look for leaning, cracked bricks, or a damaged crown/cap.
Step 2
Note any persistent smoky or unpleasant odors inside the home, which indicates a need for cleaning.
Step 3
Inside, check the firebox for cracked bricks or panels and test the damper for smooth operation.
Step 4
Look for any water stains on the walls or ceiling around the fireplace structure.
Step 5
Have a professional perform a Level 2 inspection with a camera to scan the interior of the flue for hidden cracks, blockages, or severe creosote buildup.
Step 6
During a professional inspection, an expert will get on the roof to examine the crown, cap, and flashing up close for signs of wear and water entry.

When to Call a Professional Chimney
- Before buying or selling a home (a Level 2 inspection is critical).
- Annually for a routine sweep and safety inspection before you start using it for the season.
- Immediately after a chimney fire, no matter how small it seemed.
- If you see visible, significant cracks in the brick/mortar or pieces of your chimney are falling off.
- If smoke is entering your home instead of going up the chimney.
- When you notice water stains appearing on walls or ceilings near the chimney.
- If you're installing a new appliance, like a wood stove or furnace, that will vent through the chimney.
Prevention Tips
- Schedule a professional chimney sweep and inspection annually, before the heating season begins.
- Burn only seasoned, dry hardwoods. Avoid treated wood, trash, or wet logs.
- Install a high-quality stainless steel or copper chimney cap to keep out rain, animals, and debris.
- Address small masonry cracks or flashing issues immediately to prevent water from causing more extensive damage.
- Monitor for unusual odors or performance issues and investigate them promptly.
