Attic mold can cause serious health issues, and, in extreme cases, it can even be life-threatening.
Mold spores can hide in your home’s insulation, allowing them to grow and spread throughout the house. If you think there’s mold in your attic, it’s important to act quickly!
The two main causes of attic mold are:
- Poor ventilation – If crawl spaces or other parts of your home aren’t ventilated properly, moisture can build up, leading to mold growth.
- Leaking water pipes – When water pipes leak into the attic, they often drip onto insulation, which creates the perfect environment for mold to grow.
Taking care of these issues early is key to keeping your home mold-free.
What Happens if You Ignore Mold in Your Attic?
Sometimes, you know that there is mold in your attic, but you constantly delay taking action, which can lead to a serious problem. Here are some issues that you can face in such a situation –
1. Mold Can Spread
- Mold can quickly spread to other parts of your home.
- Spores travel through the air, vents, or on clothes and pets, spreading the problem further.
- If you are not taking any action, mold can infest large areas of your home.
2. Lower Property Value
- Mold in the attic can reduce your home’s value.
- Buyers worry more about the home’s condition and the health risks mold poses.
- Even if you fix the issue, the fact that mold was once present can affect the price or make buyers hesitant to purchase.
3. Structural Damage
- Mold growing on wood and other organic materials can break them down with time.
- It weakens the attic’s structure and can lead to severe damage if left untreated.
- Repairs can be expensive, and the attic may become unsafe or unusable.
Signs That You Might Have Mold in Your Attic
1. Dark Stains on Plywood
- If the plywood in your attic has black or dark stains, it’s more than just moisture—it’s mold.
- Mold needs to be removed quickly, so call a professional as soon as possible.
2. Musty or Mildew Smell
- Trust your nose—if your attic smells musty or moldy, it’s a sign of a moisture problem.
- If you notice this smell anywhere in your home, especially in the attic, check for mold right away.
3. Wet Insulation
- Damp or wet insulation is a warning sign of mold or potential mold growth. You need to keep an eye on mold in the insulation.
- Wet insulation doesn’t work well, so it could also increase your heating and cooling costs.
4. Hot and Stuffy Attic
- A properly ventilated attic should feel breezy.
- If it’s stuffy or hot, there may be a ventilation issue, which can lead to mold growth.
5. Frost on the Underside of the Roof
- When it’s cold outside, poor ventilation can cause water vapor to freeze on the underside of the roof.
- This frost is an easy way to spot moisture problems.
6. Water Dripping from Light Fixtures or Fans
- If water is dripping from smoke detectors, lights, or bathroom fans, it’s a clear sign of moisture above—possibly in the attic—and needs to be fixed right away.
How to Prevent Attic Mold From Coming Back?
Keep Your Attic Temperature Below 68°F.
To prevent moisture buildup, keep your home’s temperature below 68°F, especially when using cooling systems like air conditioning or fans.
A cooler environment reduces the chance of black mold in the attic and helps lower energy costs.
Also, make sure to dry out your AC system overnight and clean humidifiers and AC condensers regularly to remove moisture from the air.
Use Attic Heaters
When using attic heaters, make sure to turn them off only when you know no one is in the room to prevent fire or smoke hazards.
Never leave children or pets alone near a heater, even in a low setting.
Covering pipe openings can reduce airflow. Plant areas that don’t need watering should be placed near the return vent or open windows when possible for better air circulation.
If your home has had mold issues, consider improving ventilation to prevent future problems.
Also, keep humidity low to avoid water buildup on the ceiling, and use a humidifier to control moisture levels.
Ventilate Your Attic
Even with the best prevention methods for attic mold remediation, it can still grow in your space. The key to stopping it is maintaining proper ventilation.
Make sure there is at least one window facing north or east—or more if you live in a windy area. Also, have a window facing south to prevent drafts from entering through gaps.
Avoid pushing all furniture against outside walls; instead, place plywood on the floor to create space and keep things separate. Clean this area every month to reduce dust and dirt buildup.
These tips are just suggestions, not strict rules. It’s also important that everyone in your home understands the attic’s risk of moisture and overheating—and knows not to store anything in the attic.
Don’t Let Water Collect in Your Attic
The best way to prevent mold in your home is to stop water from getting into your attic or flowing through ducts to other spaces where mold can grow.
If water collects, you’ll start seeing dark green or black patches of mold.
It may seem challenging, but there are steps you can take to avoid this. First, make sure everyone in your household understands why it’s important to prevent mold and follow these guidelines.
Also, limit contact with others who might be sick since infections can spread easily, even between rooms. Be mindful of what you touch to avoid spreading contaminants around your home.
Lastly, watch for leaks in the roof and walls, and focus on keeping bathrooms and kitchens dry and clean. Staying proactive will help you keep mold away.
How to Get Rid of Mold in Attic Spaces?
So, you’ve found mold in your attic—what’s next?
The best way to safely remove mold is to hire a professional. While you might find some DIY tips online or from friends, dealing with mold is serious and can be dangerous.
It’s a job that’s best left to experts to ensure it’s properly removed and doesn’t come back.
Hire a Professional
Removing mold is a serious job, so it’s best to hire a professional for attic mold removal. They’ll make sure not only that the mold is gone but also that the cause of the problem is found and fixed.
So, call the experts for mold removal in the attic to make your home safe and healthy again.
Their process includes:
- Finding the source of the problem
- Removing the mold
- Cleaning and disinfecting the area
- Fixing the root issue to prevent mold from coming back.
Use Vinegar to Remove Mold
While hiring a professional is the best option, you might still wonder how to handle mold yourself. Vinegar is a common suggestion for DIY mold removal.
White distilled vinegar can be used to clean, deodorize, and disinfect surfaces. However, this method takes time and effort and may not be 100% effective. Here’s how to try it:
- Ventilate the attic by opening windows and doors.
- Wear gloves and goggles for protection.
- Pour undiluted vinegar into a spray bottle.
- Spray vinegar generously on the moldy areas.
- Let it sit for an hour or longer.
- Use a soft brush to scrub off the mold.
- Dry the area with a clean cloth.
- Throw away the brush and cloth to avoid spreading mold.
Studies show vinegar can remove up to 82% of mold, but is that enough for your family’s safety?
Imagine spending hours cleaning only to have the mold return later. It might be worth considering professional help for a more thorough solution.
Removing Mold with Alcohol
Another DIY method you might come across online is using alcohol.
But don’t grab anything from your liquor cabinet—you’ll need Isopropyl alcohol, also called rubbing alcohol.
The process is the same as using vinegar, but you’ll swap the vinegar for rubbing alcohol to clean the mold.
Mold Remediation: Fixing the Root Cause
If you’ve found mold, the big question is—why is it there? Simply removing it isn’t enough because the mold will likely come back if the cause isn’t fixed.
To stop mold for good, you need to find and fix the source of the moisture. This might involve:
- Repairing a leaky roof
- Improving ventilation in your attic or appliances
- Sealing gaps between your living space and attic
- Installing proper insulation
Getting to the root of the issue ensures the mold stays gone for good.
