When to stop using the fireplace
- Stop using the fireplace if smoke comes into the room, the firebox is cracked, or debris falls from the chimney, and leave it unused until it has been assessed.
- If a carbon monoxide alarm sounds or anyone feels unwell, get everyone outside and call 911.
- If there is a fire in the chimney, leave the building and call 911.
- This website and its request form do not dispatch emergency help.

Smoke indoors, damaged firebox surfaces, or unfamiliar falling debris are reasons to stop using a wood fireplace and have the system assessed. A repair needs to address the whole path from firebox to termination.
St. Louis homes and wood fires
Public figures for St. Louis as a whole. They describe local housing and heating, not your home, so the visit still starts with your own chimney.
- Homes heated mainly with wood
- 0.1%
- 0.1% of occupied St. Louis homes heat primarily with wood, against 67.8% on utility gas — a gap of 67.7 percentage points. Columbia, also in Missouri, records 0.3%, 0.2 percentage points higher. At 0.1%, almost no St. Louis home depends on wood for heat, so most fires here are occasional — which still leaves deposits, and leaves the flue idle long enough for debris and nests to collect.

- Median year built
- 1938
- Half of St. Louis's housing units were built in 1938 or earlier, so the median St. Louis chimney had about 85 years behind it by the 2023 end of the estimates. Columbia, also in Missouri, records 1993, 55 years newer. Brick and mortar of about 1938 need repair materials matched to the existing masonry, not simply the hardest product on the shelf.

- Heating degree days a year
- 4,471
- The NOAA climate-normals station nearest St. Louis averages 4,471 heating degree days a year. Columbia, also in Missouri, records 4,745, about 6% more. Degree days measure heating demand, not freeze-thaw cycles, so 4,471 says roughly how long a St. Louis flue is in use across a year, not how much the masonry around it moves.

- Homes heated mainly with utility gas
- 67.8%
- 67.8% of occupied St. Louis homes heat primarily with utility gas, so about 32.2% run on oil, electricity, propane or something else. Wood is the primary heat in 0.1% of them. Heating fuel is not a count of fireplaces, but 67.8% on utility gas shapes what is most likely connected to a St. Louis flue.
