Homes in Pomona
Pomona's 44,373 homes are a mix: 59% detached houses, 28% apartments or units in buildings of two or more homes and 8% townhouses and other attached houses.
The biggest building period was 1950 to 1979, which accounts for 48% of homes standing today; 12% are from 2000 or later. The median home dates from 1967. 54% of homes are lived in by their owners.
In nearby Diamond Bar, 5 miles away, 50% of homes were built before 1980, so Pomona's windows are on the whole older. Nationally, Pomona's homes are older than those in 72% of the 881 US cities we have census figures for.

Out-of-square openings
With 66% 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.
Replacement windows
48% 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.
Summer sun
On the 71 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 14.5 inches of precipitation a year, and days and nights about 26°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.
Fitting them in Pomona
Shutter Boys shutters are made for you to fit yourself: an inside or outside mount takes a drill, a level and our step-by-step guide. If you'd rather hire someone, a finish carpenter or blinds installer can fit them; ask on your quote and we'll tell you if we know one near you. You arrange and pay the installer directly.
