Plantation shutters in Santa Monica

Apartments and condos

77% 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.

Patio door shutters

Out-of-square openings

With 73% 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.

How to measure

Renting?

72% of homes are rented. Shutters screw into the window frame or casing, so ask your landlord before you install; taking them down later leaves only screw holes to fill.

Replacement windows

51% 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.

Dry summers, wet winters

Barely any of the year's precipitation falls in June, July and August; most comes in the cool months. Wood takes on moisture in the wet season and gives it back in the dry one, so expect the panels to feel slightly tighter in winter than in summer. Fit them in the season you're in, and leave the hinge screws a quarter turn from tight until they've been through both.

A mild year

Few days here are very hot or very cold, so louvers spend most of the year on everyday work: angling daylight off the TV, giving privacy from the street, and opening wide on a fine morning. That makes louver size more a matter of view than of shade; bigger louvers leave more open glass.
