Your home in Jacksonville.
About 3.1% of occupied homes in Jacksonville heat primarily with utility gas. A chimney in Jacksonville may therefore serve an oil, electric, or wood-heated home, so identify the appliance connected to each flue before planning service. About 0.1% of occupied homes in Jacksonville use wood as their primary heating fuel. Most fireplaces in Jacksonville see occasional use, and even occasional use calls for an inspection before the heating season. The nearest NOAA climate normals station (Jacksonville Nas, about 7 miles from the Jacksonville city center) averages 1,097 heating degree days per year. That is a light heating season, so an occasional fire is more likely than day-to-day heating, but moisture still reaches masonry year-round, so note when water appears and have the source investigated before choosing a surface treatment.
What you can observe safely
- Record when water appeared.
- Keep people away from wet electrical components.
What to avoid
- Do not climb onto the roof or enter the chimney.
- Do not alter gas components, venting, or safety controls.
- Do not use a test fire to diagnose the problem.
Possible causes to assess
- Chimney termination condition
- Flashing or enclosure leak
- Other moisture sources
A symptom cannot establish the cause remotely. An assessment of the complete system helps determine the appropriate repair.

Can this be diagnosed from a photo?
A photo can document a symptom and help prepare a visit. It cannot confirm concealed conditions or establish that a chimney or fuel-burning appliance is safe.
