Quick Answer
Okay so here's the quick version. Your fireplace is acting up—smoky, not giving off heat—because your chimney's clogged with gunk called creosote. It's basically baked-on tar from burning wet or junky wood. This stuff is a fire hazard, plain and simple. You gotta stop burning bad wood immediately. A basic cleaning might cost you $50-150 in tools if you're brave, or you can call a pro like me for a couple hundred bucks to do it right and not make a mess. Don't mess around with this one.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Inspect Your Firewood. Check for cracks on the ends, a grayish color, and listen for a sharp 'clack' when two pieces are hit together. Use a moisture meter to confirm it's below 20%.
Step 2
Visually Inspect the Flue. Use a powerful flashlight to look up past the damper for buildup. Note if it's dusty (Stage 1), flaky (Stage 2), or shiny and tar-like (Stage 3).
Step 3
Observe Fire Performance. Build a fire and see if it starts easily and burns brightly. Note if smoke spills into the room when you open the stove door, which indicates poor draft.
Step 4
Check for Odors. Pay attention to any persistent smoky or tarry smells, especially on humid days when the fireplace isn't in use.
DIY vs Professional Costs

Switch to Seasoned Firewood | $0 - $400/cord | N/A | Ongoing |
Light Sweeping (Dusty, Stage 1 Creosote) | $50-150 (for rods & brush) | $150-400 | 1-3 hours |
Advanced Creosote Removal (Glazed, Stage 2/3) | Not Recommended | $250-800+ | 2-5 hours |
When to Call a Professional Chimney
- If you see heavy, glazed, or tarry (Stage 2 or 3) creosote buildup.

- For your annual inspection and cleaning, which is the best way to ensure safety.
- If you are not physically able or comfortable working on a ladder or roof to perform a DIY cleaning.
Prevention Tips
- Burn only well-seasoned hardwood with a moisture content below 20%.
- Maintain a hot, clean-burning fire with adequate air supply; avoid long, smoldering fires.
- Have your chimney professionally inspected and swept at least once a year.
- Install a stovepipe thermometer to monitor flue gas temperatures and ensure you're burning in the optimal range.
