Plaster walls and deep casings
69% of homes date from before 1950, when walls were plaster on lath and windows sat in deep wood casings. Plaster cracks if you drive screws carelessly: drill a pilot hole, use fixings made for plaster, and fix into the casing or the framing behind it. A deep casing is good news for an inside mount; measure its depth before you choose a louver size.
Out-of-square openings
With 93% 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.
Apartments and condos
46% of homes are in buildings of two or more units. Balcony and patio doors suit bypass or bifold panels rather than hinged ones, which need floor space to swing. Check what your HOA or building allows to show from outside before you order: most rules are about the colour seen through the glass.

Cold winters
With 106 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.
