Keep your attic mold FREE by TwoPlusCute.com

Mold can be detrimental for a house and for the health of its inhabitants. We live in a pretty humid area, which is great for vegetation but make things tricky concerning mold. From dump basements to old leaky roofs and badly installed bathroom fans, keeping mold at bay isn’t always easy.

We take several measures to passively and actively combat high humidity, especially in one of the most difficult spots: the attic. I am determined to keep our attic mold free and healthy for us, since it came to our attention during the home inspection.

Before we bought our house, the inspector (always use – a good – one!) discovered mold in the attic. We almost didn’t buy the house but a solution was found. The previous owners hired a company to professionally get rid of it.

The attic was emptied of the insulation, washed with chemicals, scraped and cleaned and finally, they applied a special paint that protects and prevents future growth.

Look at this clean beauty

For good measure, I keep checking the attic at least annually. We do have very good and thick insulation but, the humidity comes in from the roof, the vents and of course, some is bound to escape through cracks and connections. Mostly, the humidity comes from outside and the high heat in the summer, creates a too cozy environment for mold issues.

Even if ones house has perfect air flow in the attic, it will only circulate humid hot air from outside, during the warm months. Soffit vents on their own are not enough but they do help. We have plans on adding soffit vents (to improve the air flow) but until the budget allows it, we took a few easier and still very effective steps:

1. We made sure the bathroom fans are well sealed. This is my usual royal we. It was the hubby and my father in law, that went up the attics, sealed the fans and made sure everything was tightly in place.

2. We keep the insulation adequate and fluff, to mitigate hot air through any ceiling openings.

3. We check annually for any signs of mold growth. So far the special paint seems to be working lovely. Even in a house that never had mold before, I would still check, especially in high humidity areas like here in New England.

4. We add – several – closet dehumidifiers. We change them every year as they fill all the way to the brim!

 

TwoPlusCute: Keeping the attic humidity low and the mold at bay. Using closet dehumidifiers.

 

These are my favorite closet dehumidifiers. I buy ones that are fragrance free and they indeed have zero smell (I can’t stand chemical smells) and boy – oh boy – do they absorb humidity!

This post contains affiliate links but I am not affiliated with the particular product in any way. I just use it since we bought the house and I am satisfied with it. You can find it at home improvement stores, walmart and here are some amazon links to help your search:

airBOSS Closet Dehumidifier pack of 6 (<- zero fragrance) This is what we buy and we prefer to buy boxes to lower the cost (they are cheaper in bulk than per unit).

airBOSS Anywhere Dehumidifier with Activated Charcoal (<- zero fragrance) This is what I will try next year.

 

TwoPlusCute: Keeping the attic humidity low and the mold at bay. Closet dehumidifiers as extra trick.

We buy our dehumidifiers by the boxes, we place 5-10 per attic (we have two). Basically, we consider the total volume of the area we want dehumidified, using highly advanced mathematics of the sort “this look like it’s *THIS* big” and “it looks like five closets big so, we will place five dehumidifiers“.

Our method is highly accurate as you can see.

Does anybody else feels that all new house contractors should always finish the attics with anti mold treatments – or is it just me?

    Hey, Great Share.

    I have noticed during the winter months when we heat our homes, some of the heat is unavoidably lost into the unheated attic space.
    If however the attic is inadequately vented the hot trapped air will meet the cold surface of the underside of the roofing boards giving the way to the mold growth.
    Everyone should take care of this while positioning the attic.

    Nice post, thanx for sharing.

    I recently noticed that there are a bunch of light brown spots on my bathroom ceiling in the area of my shower. Is that mold, and should we be concerned about it? I want to make sure that we catch it in time, but I don’t want to take care of mold that’s not there. Though, I do appreciate that remediation companies eliminate the source of moisture, which would probably be a good thing for my bathroom, regardless of whether it’s mold or not!

    You’re so right; mold is a huge threat to your home in so many aspects. Taking action against mold and doing whatever you can to combat it is so important. You give some really good advice here for making sure your attic remains naked of mold. Thanks so much for sharing!

    A dehumidifier is great for keeping mold and mildew away from the inside of your attic. Especially if you live in a wet climate, this is a great idea. It could end up saving your home. Thanks so much for sharing!

    Lady, you know how I feel about mold – it’s my nemesis. lol H does check our attic about twice a year. That is great that you had your attic cleaned and sealed with a mold inhibitor. I will have to check out those dehumidifiers. Right now we are at 55% humidity in our home. We have received A LOT of rain these past few months. It normally looks like a desert here, but now we have so much green, it’s beautiful and odd. It seems we are getting all the rain and other states are in a drought.

    Another thing to do is to make sure the grout in the shower areas are sealed. It does make a huge difference moisture and cleanliness wise. 🙂

      Timely. My response. Is not. Sorry Julie!
      The shower grout must be sealed well – no question about it!

      Hehe, I said the exact same things the first times. I still haven’t gotten up there. I just peak my head in and look.
      Do check your attic, just to be sure it is ok and healthy. 🙂

    It is not good when the bathroom vent is directed into the attic rather than outside. Big mold issue will occur. Do you find that they work? We added the soffits a couple of years ago to help with ours. Your attic looks good. 🙂

      True, that is the first thing to check: if the bathroom vents on the outside!
      The dehumidifiers fill with water fast so, I assume they do work.
      I will buy a humidistat to check both the living areas and the attic and see what are the levels of humidity.

    Interesting post. We live in Southern California, so humidity is usually not an issue (but has been lately). I definitely never thought about it as a culprit for getting mold. I’ve always related mold to just water leaks, perhaps from roof cracks or hidden plumbing leaks. Thank you for bringing attention to this. Something for everyone to pay attention to…

      Oh, general area humidity is definitely a culprit! Dry areas (like where you live) have smaller issues (or no issues at all) but in places with a lot of rains, and humid summers, mold in attics is a concern.
      Think bathrooms; the hot humid air from showering, is enough to cause mold.
