Two kinds of moisture work on a house here. The kind you make inside, from showers and cooking and a full kettle, and the kind that arrives off the water whether you invite it or not. Both end up on your windows, and both are hard on the wrong window covering.
This is the single most common repair call we get, and almost all of it is avoidable at the point of choosing.
What moisture actually does
Real wood is the obvious casualty. Wood takes on moisture, swells, and then gives it back when the room dries out. Do that enough times and slats bow, the finish lifts at the edges, and the whole blind stops sitting straight. It rarely fails all at once. It just gets a little worse each winter until one day you notice it looks tired.
Fabric has a different problem. Fabric holds damp. In a room that never fully dries, that means mildew at the bottom of the shade, where the air is stillest and the moisture settles. Once it is in the weave it does not really come out.
Metal is fine on moisture and less fine on salt, which we will come to.
What holds up
Polysatin shutters are the answer often enough that we lead with them. They are a solid composite, not wood and not a wood veneer over something else, and they do not warp, crack, fade or peel. You can run a wet cloth over them. Hunter Douglas warranties them for exactly this kind of room, and in fifteen years of fitting them on this island we have not replaced one for moisture.
They also happen to look like painted hardwood, which is what most people wanted in the first place.
Alternative wood blinds are the other reliable option, and usually the cheaper one. You get the look and grain of wood with none of the swelling. If you want the warmth of a wood blind in a bathroom, this is how you get it without paying for it twice.
Bathrooms specifically
The main bathroom is where people most often try to reuse whatever is on the rest of the house, and it is the room that punishes that hardest.
What matters in a bathroom, in order. It has to survive the steam. It has to give you privacy at eye level while still letting light in, because a bathroom with the covering shut all day is a gloomy room. And it has to be cleanable without special care, because nobody is going to give a bathroom blind special care.
Shutters do all three. Louvres tilt for exactly the privacy and light problem, and they wipe clean.
Kitchens
Kitchens are moisture plus grease, which is a different test. Airborne cooking oil settles on everything near the stove and it is sticky. It grabs dust.
Over a sink or near a range, you want something you can actually wash. Shutters and alternative wood both qualify. A textured natural fabric near a stove will look fine for a year and then look its age quickly.
The other kitchen issue is reach. Window over the sink, and you are leaning across to get at it. It is worth talking about at the measuring stage rather than living with it.
Salt air, and what it really means
If you are on the water, or a few streets up from it on the west side, salt is in the air your house breathes. It is mild and it is constant, and it works on metal.
That does not mean metal blinds are a mistake near the water. It means the hardware matters more than the slat, and it means an unprotected mechanism in a window you leave open all summer will not last like one further inland. Tell us where the house sits. It genuinely changes what we recommend, and it is the kind of thing a national chain quoting off a floor plan will never ask you.
What to avoid
Three things we steer people away from in wet rooms.
- Real hardwood in a full bathroom. It will be fine for a while and then it will not. If you love the look, alternative wood gets you there.
- Heavy natural fabrics in a room that does not dry out. Woven woods are beautiful and they belong in a living room, not over a shower.
- Anything you cannot reach to clean. A high bathroom window with a covering you have to fetch a ladder for is a covering that stays dirty.
One more thing about condensation
If a window in your house runs with water every winter morning, no window covering is going to fix that on its own. Condensation is about warm damp air meeting cold glass, and the real answer is ventilation and heat, not fabric.
What the right covering does is stop the problem from destroying the thing hanging in front of it. That is a real and worthwhile difference, and it is worth being clear about which one you are solving.
If you are not sure
Bring us the room. Every product mentioned here is on the wall at the Bainbridge Island showroom, so you can handle a polysatin louvre and an alternative wood slat side by side and see why we keep recommending them.
Or book a free consultation and we will come to the house. We measure ourselves, we install ourselves, and we would rather talk you out of the wrong product now than warranty it later.
