Plantation shutters in St. Petersburg

Replacement windows

56% 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.

Choosing a louver size

Out-of-square openings

With 70% 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

Apartments and condos

39% 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.

Humid summers

Hot days and 52.5 inches of precipitation make for heavy summer air. Wood swells when it's humid, so give kitchens, bathrooms and laundry rooms some air: run the fan after a shower and tilt the louvers open so steam doesn't sit behind them.

Why poplar

Summer sun

On the 75 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.
