Do plantation shutters hold up in Florida humidity?

By Jesse Demick, owner, Demick Window Fashions · Updated November 2026

Yes, if they are the right kind. Composite and poly shutters, which is what Demick Window Fashions installs, do not absorb moisture, so they will not swell, warp, peel or mildew in Florida bathrooms, kitchens and coastal homes. Traditional unsealed hardwood shutters can, which is where the reputation for problems comes from.

Why some shutters fail here

Florida homes run at high humidity year-round, and bathrooms and kitchens spike well above that. Wood shutters with a thin paint finish take on moisture at the joints and end grain, swell, bind in the frame, and eventually crack the paint. The product was fine in Connecticut; it was the wrong product for Stuart.

What we install instead

Our shutters are a humidity-resistant composite with a baked finish. They do not take on water, so they stay square, the louvers keep moving freely and the finish holds. They are made in Florida, which keeps lead times to a few weeks instead of a few months, and every panel is sized to the opening.

Where shutters make the most sense

Front-of-house windows (they look as good from the street as from inside), bathrooms and over tubs, kitchens, bedrooms where you want privacy with light, and arched or specialty windows where a shade would leave a gap. We build arches, rakes and tall panels to the exact shape.

Where a shade is the better choice

Very wide sliders, where shutter panels stack deep and block the opening; windows you want to disappear completely when open; and rooms where a soft fabric look suits the decor better. We will tell you if we think a shade fits better.

Louver size and frame style

Most Florida homes look right with 3.5 or 4.5 inch louvers; larger louvers mean fewer slats and a clearer view when open. Frame style depends on your trim and whether the window is inside- or outside-mounted; we bring samples so you can see it on the wall.

Questions

Related questions

How do I clean composite shutters?

A damp microfiber cloth. No special products.

Can shutters go over a bathtub or in a shower area?

Yes, composite shutters are fine in a wet area as long as they are not directly in the spray. We have installed them inside shower enclosures with an arched window.

How long do they take?

Typically three to five weeks from measure to install, because they are made in Florida rather than overseas.

Do shutters add value to a home?

They are one of the few window treatments that convey with the house and that buyers and appraisers notice; most real-estate agents on the Treasure Coast treat them as a plus.
