Plantation shutters in Chino Hills

Rounded drywall corners

83% 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.

How to measure

Whole-house orders

With 75% 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.

Bay window shutters

Summer sun

On the 99 days a year above 90°F, closed louvers keep direct sun off the glass and out of the room. In a window that takes afternoon sun, white and light paint finishes stay cooler to the touch than dark stains.

Dry air

Only 10.1 inches of precipitation a year, and days and nights about 29°F apart. Dry air pulls moisture out of wood, so poplar louvers can shrink very slightly through their first dry season; that's normal for real wood.

Why poplar

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.
