“What’s that horrible moldy smell in my bathroom? Eek!” Yes, I confess: I am terrified of mold.
Sometimes I fear that having written so much about mold, mildew and fungus, I imagine them lurking everywhere. However, this was no fantasy—that “unwashed socks” odor was very real. Now I had to track down the cause … and get rid of it.
Why does mold cause such anxiety?
Very often, it’s a sign of something seriously wrong in the home—water damage, which can wreak as much destruction as fire, swiftly and silently. A moldy smell might be your only obvious clue.
So as a smart homeowner, take the time to learn more about moldy odors and how to get rid of them effectively.
What does mold smell like?
Mold tends to have a disagreeably tangy, earthy, musty or foul smell, as it releases mVOCs (microbial volatile organic compounds). The odor is sometimes compared to mushrooms, wet dog or “eau de locker room.”
You might be able to spot mold growth in your home with the naked eye. However, molds and mildews often grow in hidden places such as under a sink, where they’re not readily visible. That’s why being able to identify a moldy smell is important.
As well as smelling the mold, you may feel a tingling or irritation in your nose.
When is it most likely to appear?
Early spring through fall is the most common period for mold, which thrives in warm, moist conditions. Its preference: home temperature of 77 to 86 degrees together with relative humidity above 60%.
Why is mold dangerous?
Breathing in mVOCs may cause or exacerbate respiratory illness (especially if you already suffer from asthma or nasal allergies), as well as other unpleasant symptoms such as skin rashes, eye irritation, headache, fatigue, nausea and dizziness.
As far as your house goes, mold, fungus and dampness can affect materials from drywall to concrete and may threaten the building structure itself. Past or present mold issues, together with any actions you’ve taken to remedy them, must be disclosed when you sell your home.
Track down that moldy smell
The first step is to follow your nose. Go to the room where the moldy smell is strongest and see whether it stems from:
1. Appliances: clothes washer or dishwasher
2. Bathroom: towels, shower curtain, bathmat
3. Houseplants: specifically, their potting soil
4. Items that have been wet: carpet, books, etc.
5. Pet bedding
6. Secondhand purchases: vintage furniture, for example
7. Trash cans or recycling bins
You can treat many of these yourself:
• Wash fabric items in hot water (check the care label first).
• Put musty old paper or wood items outdoors in the sunshine for a day or two.
• Re-pot seriously moldy houseplants.
• Do a little heavy-duty house cleaning, for example, scrubbing moldy-smelling garbage cans or vegetable drawers.
• Try setting out an open container of natural deodorizer—activated charcoal, white vinegar or baking soda.
• Ventilate. Open windows and turn on a fan to air out the room.
• Clean small patches of mold (less than 25 square feet) on hard surfaces such as walls, countertops or ceiling with soapy hot water and a bristle brush, wearing rubber gloves and a breathing mask. Dry thoroughly.
• Never apply paint on top of active mold. However, you’ll be able to paint over the formerly moldy area after cleaning and completely drying. Use mildew-
It’s time to hire a mold removal professional when:
1. You can’t locate where the moldy smell is coming from.
2. Cleaning doesn’t get rid of the odor.
3. Your home has moldy areas totaling more than 25 square feet.
4. You see warning signals such as persistent damp patches or water damage.
5. The mold is a result of sewage or other contaminated water.
You also might need the help of other professionals to locate and repair the moisture source, such as a plumber for a water leak, a roofer for a hole in your roof or an HVAC technician to get rid of mold in your ductwork.
The cost to get rid of mold may be covered by your homeowners insurance.
