This page pulls together the most current totals and hard consequences, including about 20,100 chimney and flue fires reported annually in U.S. homes from 2018 to 2022, plus what that risk costs in injuries, deaths, and property damage.

Chimney and flue fires are not rare, and they are still largely preventable. An average of 20,100 chimney and flue fires is reported each year in U.S. homes from 2018 to 2022, with December typically bringing the highest share at 14 percent of the annual total. The pattern is even sharper up close, since creosote buildup accounts for 80 percent of chimney fires while “small” issues like debris, damaged liners, and delayed detection quietly raise the odds.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
