blinds cause mold (by BillW [NJ]) Posted on: Jun 30, 2022 11:01 AM

just a little tip (I think) I've learned:

The better a window blind is at insulating, the better it is at creating condensation (in colder times), leading to mold. This is because a cellular shade, for example, being a good insulator, makes the inside window surface colder, increasing condensation on the window and window frame, encouraging mold formation.

I have started using faux wood blinds and I suspect with their individual slats, they are not such good insulators and condensation generators.

I'd love to hear if I'm wrong or any other thoughts on this. Thanks! Bill

BillW, where do you find faux wood blinds at an affordable price? Down here in Texas, they're running $45 for the smallest ones. The ones for the windows in my properties are $65 and up. Online sites don't seem any cheaper

I would file this under tenant's housecleaning, not a LL problem.

BUt I will say that I LOVE faux wood blinds, and they have gotten a lot better about 3-4 years ago. The ones home depot sells have these benefits:

1) No end brackets, means faster install as you can just eye ball location of inner brackets.

2) No pull strings. You just push and pull the bottom of the blinds . Very little force compared to pulling on string , less wear and tear.

3) faux wood blinds are far more durable than miniblinds

4) looks way better !

I supply tenants with a little Danby dehumidifier, and make sure they run it. Eventually I’ll be supplying Santa Fe dehumidifiers, the ceiling mounted ones. Wisconsin is a moldy, allergy prone place.

Glad to read the faux wooden ones have gotten better. Might have to give those a try. Mini-blinds are so delicate these days. Break if you look at ‘em funny.

Good tip. Thanks for sharing!

AC units can cause mold. They cool the furniture and metal items which then get condensation on them when the AC gets shut off and warm humid air filters in. But also, the ultraviolet light from the summer sun will kill the mold. Block that out and mold likes that. --108.24.xx.xx

Mildew is formed primarily by the lack of ventilation, neglected mildew could form mold, this neglect is typically lazy housekeeping, to be corrected by maid service if tenant is unable to resolve.

Of course it is the resident's responsibility to wipe the windows dry & clean.

But, YES - that totally makes sense that better insulated, would hole the humidity close to and create condensation on the window.

Taylor, I had posted “rugged window treatments” on May 11, 2022 11:07 AM and people gave some advice on sources for Faux wood blinds.

After that post (above), I put up some Faux wood blinds and really like them. As David said, you can just eyeball the bracket locations, much more durable than mini blinds and looks way better. And I would add: less condensation then cellular shades or roller shades.

Busy, I do humidifiers in basements. I get the ones with pumps and pump the condensate into a slop sink or drain, so the tank does not need to be emptied. And yeah about mini blinds breaking. I show my places occupied and it stinks when half of them are broken while I'm giving a tour.

Allym, I can see that on exterior walls too. My south facing exterior has no mold and north facing has green stuff.

Vee and DJ, I rent to students and housekeeping is not their strength. Some do keep the places pretty clean, but they don't wipe the windows dry and clean.

Thank you all!!!

As a home inspector, I always told "first time" buyers to leave their blinds up about 2" when they are not at home. This allows enough air flow to minimize mildew.

Another factor is the "facing" of the window...the biggest issues are on south and west-facing windows where the sun hits them directly much of the day.

Well there's my solution, I can have the blinds 2" too short :-) Interesting on the orientation, I would have guessed it was the other way around, with the north facing windows getting colder and having more condensation. Thanks!! --74.102.xx.xx
