How To Remove Mold From Attic Wood

How To Get Rid Of Attic Mold With Tea Tree Oil

Attic Mold Cleaner
  • Oil it Up! For those who once thought essential oils were only good for making the house smell great, theres another helpful use. And, you can find many essential oils that act as a natural fungicide.
  • A good one to use is tea tree oil mix a few drops of this oil into a spray bottle with water to spray onto the offending surfaces. If you choose this method, be sure to shake the bottle well because the oil and water will naturally separate.

This technique will help to kill molds that are already there, but is equally effective to prevent mold growth in the first place.

If you dislike the smell of tea tree oil you could also try grapefruit seed oil for the same effect without the tea tree aroma.

Look For Exclusions In The Warranty

This is a big giveaway. If the service a contractor is offering doesnt actually solve the problem, the verbiage in the warranty will reveal the lack of confidence. Youll find it lurking amidst the legal jargon as an exclusion against any recurrence of moisture issues. Which, of course, is the whole reason you would seek a warranty in the first place. Mold growth only occurs when elevated moisture is present. It will not grow in a dry attic. Therefore, if a warranty becomes void in the presence of elevated moisture, the treatment hasnt accomplished anything.

Removing Mold From Wood

Removing mold from wood is easy if it has not spread far and wide. Before starting, put on your protective wear, especially a mask and gloves. First, vacuum up the area with the mold. This will suck up any loose spores on the surface of the wood. Next, scrub the area with soap and water. On bare, untreated or unpainted wood, you can use bleach. Soak up any cleaner and extra moisture.

If mold is still apparent in the wood, you can try to sand it out. Note that sanding will take off any finish and some of the wood. Since mold can live deep in the pores of wood, you may need to do a lot of sanding to fully remove it.

What Does The Mold Growth Typically Look Like

How To Remove Mold From Ceiling Joists

Mold growth on the sheathing occurs in either a flat, low profile configuration or a fuzzy, 3 dimensional pattern. The flat, low profile growth can often look like soot or staining. In fact occasionally a home inspector will misidentify the mold growth as soot from a fire. Notice the dark staining in the first picture. This type of mold growth will not smudge or wipe off. The dark discoloration will remain long after the mold has stopped growing.

Below is an image of heavy 3-dimensional mold growth on the sheathing. Beneath the fuzzy growth, areas of staining can be observed as well. This type of attic mold is less common and typically easier to remediate. Because the staining is limited, a thinner layer of encapsulant can be applied.

Reader Question: Is It Ok To Apply A Sealer Or Wood Preservative Over Black Stains On Plywood Roof Sheathing

Last September I had a new garage roof fitted and within 7 months the plywood used inside developed black mould spots. The company that fitted the roof said it was caused by condensation. Having wiped the roof with a mild detergent I was left with black stains on the plywood. I would like to know if it would be ok to put a wood preservative on it despite the stains – don’t want it to come back.

Would appreciate your advise? –


Yes you can apply a wood preservative, leaving cosmetic black stains under the preservative.

But if you do not find and fix the cause of condensation I’d still expect future trouble. You may find stains or mold appearing on other wood or mold-friendly surfaces in the same area if indoor moisture levels are high, or if there is building insulation present that may become mold contaminated.

What To Do About The Existing Mold

Mold in the Attic

This is kind of debated.

In my personal/professional opinion, once you stop the moisture you will stop the mold and it will go away naturally.

However, if you have a large issue that is getting into your home you might want to have remediation done.

Some companies will try to up-sell mold remediation in your attic, but in most cases I do not see a reason for it since you are not spending your time in the attic.

I would always recommend having an inspection done by a third-party licensed home inspector before paying a remediation company to do large amounts of mold remediation and air sealing.

    How To Treat Black Mold In Attic

    Depending on the size of the black mold growth, you can try removing it yourself. For small growths, there are several home remedies to clean them. Here are the steps:

    • Remove all the contaminated stuff. Black mold grows easily, so you need to remove all objects that may make the mold grow again. Make sure to wrap them tightly in plastic, to prevent the mold spores from growing and spreading.
    • Prepare proper cleaning tools. You need a mask, gloves, and goggles. Make sure to dispose of all of them after the cleaning. Again, you need to wrap them tightly with plastic, before discarding the objects.
    • Make sure there is enough ventilation in the attic. Poor ventilation will make you get exposed to flying spores that cannot get out.
    • Mix some detergent with warm water until foamy. Use this mixture to scrub the moldy surface as hard as you can. This solution is perfect for nonporous materials, and not ideal for wood.
    • Detergent does not work? Add a half tablespoon of baking soda into the water in a medium-sized spray bottle . Shake the bottle and spray the mixture to the moldy surface. Scrub the mold clean before spraying again. This time, let the mixture to dry by itself.
    • Discard all the tools you use for cleaning . Wrap them in plastic before throwing them out. This is to prevent mold spores from flying around.

    Getting Rid Of Basement Mold

    Mold in the basement can be persistent, given the nature of basements they tend to be much more humid than above-ground levels and typically have poor ventilation and little air flow, a combination that can cause mold to flourish. And of course, basements can be prone to flooding, due to extreme weather or undetected leaks in the pipes or sump pump. In addition, once mold develops, cinder blocks or concrete walls can be difficult to clean due to their rough texture.

    To get rid of mold in the basement, scrub the walls using a large brush, and keep in mind that porous surfaces such as ceiling tiles or drywall might need to be removed and replaced. If basement carpet has become moldy, sweep it to loosen the mold and let it dry in the sun if you can move it, or use high-powered fans to remove moisture if its affixed to the floor.

    To prevent mold in the basement, you need to alter the conditions that can cause it to grow. First, remove dampness by installing a dehumidifier and making sure the dryer vent exhausts externally, if you use your basement for laundry. Then turn your attention outside: Shore up cracks and other foundation issues, and make sure that your soil is properly graded so that rainwater or melting snow goes away from the house, rather than collecting near your foundation.
