What Missouri does to a house
A state is a big place — these are the ranges, not averages. The county pages pin the numbers down.
- Climate
- Zones 5b–7b. Freezing days run from ~63 to ~137 a year depending on the county.
- First freeze
- Usually lands anywhere from October 15 to November 7 depending on the county.
- The air
- Runs from temperate to humid, county by county.
- The load
- Split duty: 30 counties lean heating, 0 lean cooling — the county page calls yours.
- Termites
- Moderate pressure as a state band.
- Radon
- EPA Zone 1 — the highest band — statewide. A one-time test settles it either way.
- Labor
- Labor sits near one level statewide — every price band on this site adjusts to the county anyway.
