Homes in Westminster

Westminster's 50,471 homes are a mix: 54% detached houses, 34% apartments or units in buildings of two or more homes and 10% townhouses and other attached houses.

The 1980s and 1990s built 42% of today's homes, more than any other period we count. 34% are older than that and 24% newer. The median home dates from 1987. 62% of homes are lived in by their owners.

In nearby Broomfield, 5 miles away, 21% of homes were built before 1980, so Westminster's windows are on the whole older. Nationally, Westminster's homes are newer than those in 72% of the 881 US cities we have census figures for.

Rounded drywall corners

66% of homes here were built from 1980 on, and many houses of that era have rounded ("bullnose") drywall corners around the windows instead of square returns. A shutter can't sit flat against a curve: choose an outside mount with a frame that clears the corner, or an inside mount if the flat part of the opening is deep enough for your louvers.

Cold winters

With 149 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.
