California shutters in Niagara Falls

Plaster walls and deep casings

31% of homes date from 1960 or earlier, when walls were plaster on lath and windows sat in deep wood casings. Plaster cracks if you drive screws carelessly: drill a pilot hole, use fixings made for plaster, and fix into the casing or the framing behind it. A deep casing is good news for an inside mount; measure its depth before you choose a louver size.

How to install

Out-of-square openings

With 61% of homes built in 1980 or earlier, 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 6 mm, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.

How to measure

Whole-house orders

With 66% 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.

Bought to stay

Owners live in 70% of homes, and shutters are usually bought to stay with the house. Poplar takes paint well, so they can be repainted years from now if you change a room's colours. Keep your order list: it records every size if you add a room later.

Why poplar

Cold winters

With 134 days at or below freezing 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.

Why poplar

Summer sun

On the 10 days a year above 30 °C, 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.
