Homes in Florissant
Florissant is a city of houses: of its 23,064 homes, 79% are detached, 2% are townhouses and other attached houses and 19% are apartments or units in buildings of two or more homes.
The biggest building period was 1950 to 1979, which accounts for 84% of homes standing today; 3% are from 2000 or later. The median home dates from 1963. 67% of homes are lived in by their owners.
Of the 13 Missouri cities we have census figures for, Florissant has the highest share of older homes. In nearby St. Charles, 10 miles away, 38% of homes were built before 1980, so Florissant's windows are on the whole older. Nationally, Florissant's homes are older than those in 99% of the 881 US cities we have census figures for.

Replacement windows
84% of homes went up between 1950 and 1979, and most of them have had their original windows replaced since. A replacement window often sits further into or out of the wall than the old one, so the depth you have for an inside mount may differ from window to window in the same house. Measure every opening rather than copying one.
Out-of-square openings
With 90% of homes built before 1980, many openings have had decades to settle. Measure each one's width at the top, middle and bottom, and both diagonals. If the diagonals differ by more than about ¼ inch, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.
Whole-house orders
With 79% of homes detached, most orders here cover a whole house: bedrooms, a patio door, perhaps a bay. Put every window in one list in the designer so the louver size and colour match from the street, and if you have an HOA, send it the drawings before you order.

Cold winters
With 85 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.
Humid summers
Hot days and 42 inches of precipitation make for heavy summer air. Wood swells when it's humid, so give kitchens, bathrooms and laundry rooms some air: run the fan after a shower and tilt the louvers open so steam doesn't sit behind them.
Fitting them in Florissant
