What Maryland 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 6a–8a. Freezing days run from ~64 to ~132 a year depending on the county.
- First freeze
- Usually lands anywhere from October 11 to November 14 depending on the county.
- The air
- Runs from temperate to humid, county by county.
- The load
- Split duty: 1 county leans 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.
- Wind
- 10 counties carry hurricane exposure — prep there is a season, not a surprise.
- Labor
- Labor sits near one level statewide — every price band on this site adjusts to the county anyway.
