Attic Mold Removal: Why Mold Grows in Attics and How to Remove It

March 10, 20269 min read

When you think about mold, your first thought is probably not that it grows well in the attic. However, moisture from an inefficient or leaky roof, coupled with a lack of ventilation, means that it can and does happen.

You might not even know that you have mold in attic spaces until it has grown so prevalent that you see spots on the ceiling when you’re up there. Alternatively, perhaps you go up into your attic often but have noticed some unpleasant smells or seen some discoloration on the floorboards.

Either way, if you suspect that you have attic mold, then your concerns are valid, and action needs to be taken. Let’s take a look at what causes attic mold and what steps we recommend taking if you discover that you do have it in your home, and why attic mold removal is often necessary.

What is Attic Mold?

Mold is a type of fungi (an organism that does not produce its own food but gets energy from what is already present) that grows in places with excessive moisture or humidity. It commonly feeds off of cellulose, the substance that makes up most of the structure of homes.

Attic mold is one of the most dangerous types of indoor mold because it is so difficult to detect until it has permeated your entire home’s structure. This is because the attic is a dark and humid area that is far from frequent foot traffic, so it is easy for mold in attic areas to grow there unnoticed.

If you do not take care of the mold in your attic, it can cause health problems such as allergies, irritation of the eyes, skin, and lungs, headaches, difficulty breathing, and a general feeling of unwellness.

In some cases, it can cause serious health conditions such as asthma and bronchitis. So, if you have mold in attic areas, it’s essential to take steps to remove it through proper mold removal.

Why Does Attic Mold Grow?

Mold grows when the conditions are right for it to do so. It requires moisture, food, and air.

Usually, if these three things are controlled in a home, mold will not grow. But if there’s a problem with one or more of these three things, that’s when mold might take hold.

For example, if there’s a leak in your roof and water is running into the attic, that’s the first condition that needs to be met for mold to grow. But if there’s no way to get rid of that water or if the attic doesn’t have good ventilation, the water will sit there, providing food for the mold.

And with no air circulation, mold in attic environments will grow quickly and can soon spread throughout the attic, eventually requiring professional attic mold removal.

Signs of Attic Mold

Because the attic is a space that most homeowners do not check very often, mold in attic areas can grow for quite some time before it is noticed. However, there are a few common signs that may indicate that mold is present and that attic mold removal may eventually be needed.

  • Discoloration: Mold can cause spots on your attic floorboards. Mold has a specific look to it, so if you see it, it’s a clear indicator that there is mold in attic areas growing.

  • Bad Smell: A bad smell in your attic is another sure sign of mold. Often, the smell will come from where the mold has grown. If you notice a bad smell in your attic, that is another sign of mold in attic spaces.

  • Black or Blue Spots: These spots on your ceiling are often shaped like patches. These are signs of mold growing on the joists that hold up your ceiling.

  • Itchy or Runny Eyes or Other Respiratory Issues: If you are experiencing itchy eyes or a runny nose while in your attic, then it could be due to the conditions that allow mold to grow.

  • Smoke detectors, Light fixtures, or Bathroom Fans Leaking Water: This is a sure indication that moisture is present in the floor (or attic) above you and that it must be dealt with to prevent further mold growth and the need for attic mold removal.

How to Remove Attic Mold

If you find that you have attic mold, you’ll need to get rid of it. The most obvious solution is hiring a professional attic mold removal service like us, ZeroMold. We use specialized equipment to get rid of the mold and sanitize your attic so that the problem does not return through professional attic mold removal.

However, if you’d prefer to tackle the mold removal project yourself, here are a few things you can do:

  • Keep the Area Sealed Off: Spread plastic sheeting in your attic using tape. This stops mold spores from dispersing throughout the house while you attempt mold removal.

  • Wet Vacuum: To get rid of the accumulated water, use a wet vacuum. The wet vacuum will suck up the mold spores. Do not use a dry vacuum. It will just cause mold to be released into the atmosphere.

  • Organize and Dry the Space: Sweep and scrub the area after applying the vacuum treatment. Use heaters or fans to dry out the attic. Dehumidifiers can also be useful. Before moving on to the next step, ensure the attic is tidy and dry.

  • Blasting with Dry Ice: Mold removal via dry ice blasting is highly successful. It can access small crevices, gaps in framing, and other challenging places. Dry ice blasting loosens up the mold on the surface of the attic and then uses thermal shock to remove it.

  • Chemicals: Although using anti-microbial agents can be slightly risky, they aid in the mold removal process. You can always hire ZeroMold to do it for you if you don’t feel comfortable doing it yourself.

Natural Solutions

There are natural ways to get rid of mold. This should be the best option for you if you have reservations about the use of chemicals. Start by cleaning your attic, bagging up anything to dry it out, and completely drying the attic using fans or dehumidifiers.

Next, combine a cup of water with white vinegar or tea tree oil. Then, put the mixture in a spray bottle. Spray it on the section of your attic that is occupied by mold.

You can also use one part hydrogen peroxide with two parts water to remove heavy molds. Spray it on the moldy areas and let it sit for an hour to see the results. In the same manner, hydrogen peroxide can also be helpful for tough molds, which is natural and safe to use during smaller mold removal attempts.

Frequently Asked Questions About Attic Mold Removal

1. What causes mold in attic spaces?

Mold in attic spaces usually develops when moisture builds up, and the area does not have proper ventilation. Common causes include roof leaks, poor attic ventilation, bathroom fans venting into the attic, or trapped humidity. When moisture sits on wood and insulation, it creates the perfect environment for mold to grow.

2. Is mold in the attic dangerous?

Yes, mold in attic areas can become dangerous if it spreads. Mold spores can move through the home’s air circulation and may cause allergy symptoms, respiratory irritation, headaches, or breathing difficulties. If left untreated, mold can also damage structural materials in your attic.

3. Can I remove attic mold myself?

Small areas of mold can sometimes be cleaned using proper safety precautions, but large infestations usually require professional attic mold removal. Mold often grows deep in wood or insulation, which makes complete mold removal difficult without specialized equipment.

4. How much does attic mold removal cost?

The cost of attic mold removal depends on how widespread the mold is, the size of the attic, and what caused the mold growth. In many cases, a professional inspection is needed to determine the extent of the problem before providing an accurate estimate.

5. How can I prevent mold from returning to my attic?

Preventing mold in attic spaces usually involves controlling moisture. This can include fixing roof leaks, improving attic ventilation, sealing air leaks from the home below, and ensuring bathroom or kitchen vents exhaust outside rather than into the attic.
