Indianapolis has a lot of houses. A lot of old houses. The city proper has neighborhoods like Irvington, Meridian-Kessler, and Fountain Square where most of the housing stock is 80 to 100 years old. Homes in these areas were built with plaster, updated at some point with patches of drywall, and passed through multiple owners who each left their own layer of repairs. Working on drywall in an Indy home often means figuring out what you're actually dealing with before you can decide how to fix it.

The climate here is standard Midwest: cold winters with freeze-thaw cycles that stress foundation walls and cause seasonal cracks, hot summers with enough humidity to slow your finishing timeline significantly. June, July, and August in Indianapolis average relative humidity around 70% in the afternoons, which means joint compound that would dry overnight in spring might need an extra day in summer without a dehumidifier running.

The newer suburbs north of the city, places like Carmel, Fishers, and Zionsville, have a different situation. Homes out there are mostly 1990s and 2000s construction with standard drywall throughout, and the most common issues are screw pops, minor settling cracks, and the occasional water damage from roof or plumbing problems.

Climate: Hot humid summers, cold winters. Average July high around 85°F with humidity 60-75%. January averages around 22°F low.
Typical Homes: City neighborhoods average 60-90 years; suburban areas 20-40 years
County: Marion County
