A chimney repair estimate starts with documented condition: what is damaged, why it is happening, and what remains sound. The project scope, access, materials, and any permit or structural requirements determine the work to price.

Your home in Green Bay.
About 75% of occupied homes in Green Bay heat primarily with utility gas. Many chimneys in Green Bay 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 Green Bay use wood as their primary heating fuel. Most fireplaces in Green Bay see occasional use, and even occasional use calls for an inspection before the heating season. The nearest NOAA climate normals station (Green Bay Botanical, about 6 miles from the Green Bay city center) averages 7,791 heating degree days per year. That is a long heating season in which venting runs for months and freeze-thaw cycles work on exposed masonry, so check exposed brick and the crown after winter from a safe position.
Compare complete scopes
Ask whether the estimate includes investigation of water entry and how concealed damage will be handled. A written change-order process makes additional work easier to evaluate before you approve it.
Keep repair choices tied to the building
For older masonry, material compatibility matters as well as appearance. NPS guidance explains why an incompatible mortar or coating can make deterioration worse; the estimate should identify the proposed materials.
