A crack needs context: location, movement, water entry, and the surrounding masonry. Widening cracks, leaning, or loose masonry call for keeping clear and prompt professional evaluation.

Your home in Springfield.
About 59% of occupied homes in Springfield heat primarily with utility gas. Many chimneys in Springfield therefore vent a gas furnace, boiler, or water heater rather than a wood fire, and those flues still need inspection for liner condition, moisture, and blockage. About 0.2% of occupied homes in Springfield use wood as their primary heating fuel. Most fireplaces in Springfield see occasional use, and even occasional use calls for an inspection before the heating season. The nearest NOAA climate normals station (Westfield Barnes Municipal Airport, about 10 miles from the Springfield city center) averages 6,613 heating degree days per year. That is a substantial heating season, so plan inspections before the first fire and look for new water or masonry changes after winter from a safe position.

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.
