How Do You Naturally Remove Mold From Attic
After completing the cleaning and drying process of your attic, there are a several steps to follow for natural treatment.
Step 1- Safety Gear
Protection is everything! Shield yourself from the toxicity of attic mold. While you work in your attic, spreading of the spores is natural. Cover yourself with the following.

Vinegar Kills Mold Growing On Porous Surfaces
Porous building materials, such as drywall and insulation, absorb moisture. When high humidity levels or water from a leak persist, any organic materials, such as built-up dirt and dust or even cellulose used in building materials, can provide mold with the nourishment it needs to grow.
When you bleach porous materials, the chlorine stays on the surface. The water in bleach solutions sinks in and can contribute to regrowth. For this reason, acidic or alkaline cleaning agents that get absorbed are more effective.
Most mold cleaning experts recommend pouring full-strength vinegar into a spray bottle and applying directly to mold growing on walls. Acetic acid will kill mold on the surface and get absorbed into materials to eliminate the mycelium.
Allow vinegar to remain on a moldy wall for two hours before scrubbing the surface with a stiff-bristled brush. Wipe down the wall and wait for it to dry. It may be beneficial to speed up this process by running new fans unexposed to spores or a dehumidifier to draw out moisture. Check treated surfaces over the following days for any traces of recurring growth.
If more bubbling or scrubbing action would be helpful for eradicating stubborn mold, consider following an application of vinegar to walls with a paste of baking soda and water. You can also mix one-half cup of Borax or sodium borate powder with one-half cup of white vinegar and one cup of water.
What Does The Mold Growth Typically Look Like
Attic mold often appears as a thin grey or black layer on the very top of the insulation. The dimensionality of the growth is difficult to determine, as the underlying insulation presents a rough and uneven surface. If the mold growth is due to high humidity and condensation, as is usually the case, the mold growth will only occur on top of the insulation. In the image below, notice how the mold growth uniformly covers the insulation, but is not found on the lower layers, which were disturbed during the inspection.

How To Remove Mold On Insulation
Have you ever tried to remove mold? If yes, did you achieve your intended goal? And after all your efforts, did you have a permanent removal?
Removing mold may not be as easy as you think. It can be a challenging task for anyone to complete. But do you ever imagine why specialists exist? A certified remediation company will save you money, headaches, and time.
Improper Bathroom Or Kitchen Fan Exhaust
Dryer exhaust vents, kitchen exhaust fans and bathroom exhaust fans are designed to pump moisture OUT of your home. So make sure that they terminate outside your home and NEVER in the attic.
Also plumbing stacks in the attic can be a source of condensation, which can lead to attic mold growth. Plumbing stacks can also emit hazardous gasses, so make sure that they do not terminate inside the attic.

Fiberglass Insulation May Have Been Contaminated By Airborne Mold Spores Or Other Pathogens From Other Sources
Just below is an individual Curvularia-like mold spore to the left of what is probably a fragment of gypsum or drywall material.
More subtle in this photo are individual Penicillium/Aspergillus mold spores.
Small and colorless these are harder to see unless the microscopist takes care and time.
The combination of these particles in a vacuum sample of fiberglass insulation suggests that this insulation became contaminated by airborne debris, perhaps during demolition of moldy drywall.
Below is a large hyphal fragment in fiberglass insulation from this observation we can be confident that wet conditions and growing mold have been present in the building where this sample was collected.
The image does not mean that this fungus was necessarily growing in or on the fiberglass itself. As we said in our introduction, a few isolated spores in insulation are insignificant. All mold is everywhere, all the time – at low levels.
But when we find large hyphal fragments in any indoor environmental sample we know that most-likely there is or was significant nearby mold growth in or on the building.
Below are multiple Stachybotrys chartarum mold spores in a fiberglass insulation sample nd in the background I see some colorless Pen/Asp spores as well.
This sample strongly suggests that there has been demolition of moldy materials, probably drywall, in the area where this fiberglass was exposed.
There is no evidence that these fungi are growing on or in this particular insulation sample.
Mildew Smell In Your Attic
Trust your nose. A musty or moldy smell in the attic means theres a moisture problem somewhere. If you suspect that you smell mildew anywhere in your home, especially in your attic, you may have a mold problem and should check it out right away.
Wet insulation
Not only is this a sign that you may have a mold problem, but when insulation gets damp or wet its ability to insulate becomes significantly diminished, costing you extra money to heat/cool your home.

How Do You Know When You Have Mold In Your Insulation
The biggest and most reliable indicator of mold on your fiberglass insulation is visual. If you see dark blackish discolorations in and on your insulation, this may be mold.
But its worth understanding that not all discolored insulation necessarily means that mold is growing on that insulation. Dark spots on insulation may be grime and dust rather than mold growth.
If the dark spots on fiberglass insulation smear when pressed, or if they have a slimy or fuzzy appearance, this is likely mold growth.
There are a couple of further things to keep in mind, though.
Number one, it can be difficult to inspect fiberglass insulation, depending on where its located.
Number two, both insulation and mold can be hazardous to handle if youre untrained.
Often, your best option is to schedule an inspection with a licensed professional to give a thorough assessment as to whether any mold is growing and what might need to be done.
Diy Attic Mold Removal
To clean a hard surface , simply add hydrogen peroxide OR white vinegar to a clean, empty spray bottle undiluted. Never mix these chemicals! Choose one or the other.
Hydrogen Peroxide
When using hydrogen peroxide, spray the area to clean thoroughly, and let it sit for 10-15 minutes. Then, scrub the area, and rinse it clean with water. Repeat if needed.
White Vinegar
For white vinegar, spray the area to clean thoroughly, and let it sit for at least 15 minutes or up to one hour. Then, scrub the area, and rinse it clean with water.
Baking Soda
To use baking soda, add a teaspoon to a tablespoon of baking soda to a clean empty spray bottle and fill the bottle ¾ full of hot water. Shake to dissolve. Spray the area and use a scrub brush to clean the mold away. Then, rinse the area with clean water.
When using baking soda, it usually works best with a white vinegar spray following the baking soda, but not at the same time. The baking soda should be scrubbed away and rinsed before spraying with vinegar.
Baking soda is a base and vinegar is an acid. When they are used together, they react to form carbon dioxide gas and heat. The chemicals then are neutralized and have less cleaning power than they would if they had been used separately.

Not All Stained Insulation Is Harmful And Other Building Materials Are Also At Risk
Watch out: not all stained or dirty-looking fiberglass is moldy or even contaminated.
A very common source of black, gray or tan “stains” on building fiberglass is air bypass leaks that deposit ordinary house dust or building dust on or in the insulation as air passes over or through the material.
This is not mold contamination and this fiberglass insulation – shown in our photo – does not need to be removed. Rather it makes sense to find and fix those air bypass leaks.
See for details INSULATION STAINS – AIR BYPASS LEAKS
Keep in mind that the air bypass stains as well as mold, insect fragments or other contaminants described in this article can also be found on or in many building materials and in porous materials may be difficult or impossible to clean economically.
Scrub Moldy Surfaces With Mold Cleaner
- Scrub the surface mold stains from walls and wood trim with a mixture of one quart water and 1/2-cup bleach mold cleaner to kill the mold.
- Use a soft brush and work until signs of the mold disappear.
- After scrubbing the surfaces, allow the bleach solution to continue to penetrate the surfaces and dry.
- Wipe off, but DO NOT RINSE these surfaces.
- Set trim in direct sunlight to dry. Scrub concrete with TSP or automatic dishwasher detergent.

Mold In Crawl Spaces Insulation
Homeowners usually forget about crawl spaces until something is taking them there. Often, these spaces are out of sight and tend to be an irresistible home for mold when they are wet. In the long run, it grows and extends to the insulation in the area.
For example, an insulating material like fiberglass in your crawl area will soak up moisture and hold it against the floor joists and sub-flooring. Practical signs of mold in crawl spaces include:
- Awful odor or stale smell
- Greenish or black spots on insulation and walls
- Rotting or decaying beams and joists
- Itching eyes, runny nose, or coughs

How To Get Rid Of Mold On Your Insulation
Once a section of insulation has begun to grow mold, youll need to get rid of that insulation. The bare minimum is to replace the insulation, as theres no practical way to clean the mold off the insulation.
But one very important thing to keep in mind is that if mold is growing on insulation in an area of your house, its almost certain to be growing in other areas in that space. As we discussed, the materials of fiberglass insulation are naturally mold-resistant. If mold has managed to grow on the insulation, its very likely to be growing elsewhere in the vicinity too.
And once mold has begun to grow, you need to get rid of all of it, otherwise it will quickly return to the area. Mold emits mold spores into the air, that they can settle on nearby surfaces and spread further.
Not to mention, mold is a hazard to your health and the health of your family. Mold aggravates allergies, leads to respiratory problems, and can cause a handful of other health conditions.
This means that usually, youll need to go further than simply getting rid of the mold-infested insulation. Youll need to also thoroughly dry, scour, and clean the walls and surfaces in the area where youve discovered mold.
Removing moldy insulation, cleaning the room or area, and installing new insulation can be a lengthy and tricky process. Youll need specialized safety gear both to handle the fiberglass insulation and to be in the presence of mold.

How To Remove Mold From Attic
Every house at least once gets mold infestation. It is easier to spot and easiest to have a professional service remove it. But there are steps that you can follow to remove it yourself. Here is what you can do for attic mold removal.
Step 1:
Seal the surrounding
Use tape and spread a plastic sheeting in your attic. This prevents the spreading of mold spores around the house.
Wet Vacuum
Use a wet vacuum to clear the accumulated water. The wet vacuum will suck up the mold spores. Avoid using a dry vacuum. It will only release mold into the air.
Clean up and dry the area
After using the vacuum treatment, sweep and scrub the area. Dry out the attic with fans or heaters. A dehumidifier will be of help. Ensure that the attic is clean and dry before you step ahead with the next method.
Step 2
Dry ice blasting
Dry ice blasting is very effective in the mold removal process. It reaches tight spaces and gaps in framings and other difficult-to-reach areas. With its thermal shock, dry ice blasting loosens up the mold and lifts it from the surface of the attic.
Chemicals
Chemical treatments can be a little hazardous but the use of anti-microbial chemicals help to remove mold. They can be combined with other methods as well.

Vinegar Also Kills Mold On Non
Vinegar is also effective for removing mold from hard, non-porous surfaces. Although the leading surface disinfectant, household chlorine bleach, is effective for this application, it is harsh and toxic.
A solution that consists of a 5% to 6% concentration of acetic acid in water is much milder and may be less likely to irritate the skin, eyes or mucous membranes of the person who is attempting to clean up the mold. Vinegar may also be less likely to damage or discolor walls than strong alkaline bleach solutions.
When you apply a solution of bleach diluted in water to mold on hard, non-porous surfaces, this treatment should be sufficient to eliminate mold. In the case of tiled walls, bleach will not penetrate into porous grout between tiles but can still wear down sealant. Vinegar can be a better choice for walls that combine non-porous tiles and porous grout.
If you are cleaning a non-porous surface, it may not be necessary to wait as long as two hours before scrubbing or wiping down a moldy wall. Within five minutes of applying full-strength or diluted vinegar, it should become easier to remove mold from walls.
Hiring A Professional To Remove Mold
If you hire the right professional, you will obtain peace of mind for yourself and family that the job was done right, and you can regain the clean healthy air in your home that you and your family deserve. You can also breathe a sigh of relief that you do not have to worry about nasty mold impacting your health and others living with you.
And of course, you can rest easy knowing that if and when you decide to sell your home, the transaction will not be held up or killed by a previously unknown attic mold problem.
Some techniques a mold professional may utilize:
Mold killing chemicals
Professional mold remediation companies follow industry guidelines when removing attic mold. The most common type of remediation is chemical based using powerful cleaning agents to kill the mold, and then covering the attic with powerful anti-fungal sealers that will prevent mold from growing back. Chemical based mold remediation is highly effective and usually costs the least, so its the most popular option.
Abrasive blasting to remove mold
Another method thats highly effective, but usually much more expensive, is abrasive blasting. In this method, the mold professional will blast off the top layer of wood using a medium such as dry ice, soda ash, or sand. This method is very impressive, but is usually loud, expensive and requires a lot of labor hours. Therefore, this method is much less popular
