Secure the room by hanging heavy plastic sheets over doors, windows, air registers and vents. Leave one window open so that you can blow contaminated air outside. Position a heavy fan to vent out the window, and let it run constantly while you work.

Power Tip: Be careful to angle the fan so that it doesnt blow directly on the moldy subfloor.

Making A Mold Removal Spray

According to, HowToRemoveBlackMold.com, to make a mold removal spray, mix half white vinegar and half water in a spray bottle and spray down the mold colony. Tea tree oil and white vinegar are both completely natural and safe for wood and have strong fungicidal properties.For larger mold jobs, vinegar and tea tree oil may not be strong enough.

You can also try hydrogen peroxide, which is a strong but safe and natural alternative. Mix 1 part peroxide with 2 parts water and spray it on the moldy area, letting it dry for an hour. Scrub the area with a firm wire brush and allow it to dry one last time. Remove the plastic sheeting and repair any leaks to prevent new mold spores from emerging in the future. If your attempts at attic mold removal still don’t work, contact a mold remediator for further advice, as some mold infestations are so large, they are better handled by a professional.

Its quite rare for mold growth to warrant the replacement of the sheathing. While it can look unsightly, it takes quite a while to structurally damage the sheathing. If youre already due for a roof replacement, replacing a few sheets makes sense. If your roof is in good shape, I rarely recommend tackling the sheathing. Focus on improving the roof ventilation to ensure the mold growth does not continue.

Causes Of Mold In Your Attic

If you find black spots in your attic and you are thinking it could be harmful black mold, you do not necessarily need to panic.

Mold located on ductwork, on roof decking, trusses, or just about anywhere in the attic is simply a problem of excessive moisture.

Mold will survive in almost any environment that is the right temperature, has moisture , and has something for food .

So, in order to stop the mold we need to stop one of those three things. Moisture is really the only one we can control in our attics.

Why Does Mold Grow In The Attic

7 Things You Must Know Before Attempting DIY Attic Mold ...

Attics in the San Francisco, CA area are ideal places for mold to thrive. Often left unused, the attic is hot, humid and contains an abundant organic food sourcewood sheathing. Mold requires moisture, oxygen and a food source to grow and, the attic provides all three forms of nutrients.

The moisture issues that cause mold growth in the attic may be attributed to any of three scenarios: insufficient or blocked ventilation, roof issues or leaks and the incorrect exhaustion of bathroom fans or dryer vents. If the attic were moisture-free, mold spores would have no chance of surviving.

The ventilation system in the attic normally works by allowing outside air to enter through the soffit vents and escape through the top ridge vents. When the vents are blocked with insulation, however, the warm outside air will stagnate inside, condense on wood, and allow mold to develop.

Roof leaks can lead to localized mold growth. The roof should be examined periodically for leaks. Dryer exhaust vents are designed to direct moisture outside the home. It is important that homeowners ensure the vents lead outdoors and not into the attic, where moisture and mold problems can begin.

Prepping The Area For Attic Mold Removal

An attic is a very confined space, and if your mold happens to be a toxigenic variety, you want to take every possible measure to limit your exposure. GESQ suggests first covering yourself in safety gear, including a breathing mask, safety goggles, rubber gloves and protective coveralls with a hood. Next, empty out your attic. Place everything in thick trash bags, seal the, tightly and take the contents outside to dry.

Examine the insulation along the rafters if it been affected by mold, it is necessary to remove it in thick trash bags immediately and replace it with new insulation after you complete your remediation effort. Seal any openings like vents and windows using plastic sheeting so as not to spread the mold to other areas of your home. With your attic contained, you can begin drying the mold. Working with active mold will spread the fungus, but you can neutralize the spores by drying them first. For best results, use fans, a dehumidifier or heater.

How To Kill Attic Mold With Vinegar

  • Pickle the Walls! Well, not exactly pickle, but that wonderful kitchen cleaning stand-by white vinegar is a natural antimicrobial making it a perfect all-natural way to remove mold from your attic.
  • Simply mix half vinegar and half water in a spray bottle and spray onto the moldy surface. For stubborn molds, you may wish to use a stronger dilution of vinegar to water. Much like the essential oils, this method will begin to kill mold that is already in place and helps to inhibit future growth.

Does The Building Need To Be Sterile Is The Object To Reach A Mold Spore Count Level Of Zero

No, the building does not need to be sterile, nor should you seek a “zero mold count”. We have worked on cases where sterility was a necessary cleanup goal: medical facilities such as in operating rooms and treatment rooms. But in a normal office or home there is always some airborne mold along with lots of other airborne particles in building dust.

No washing, sanding, scraping, or other surface cleaning will remove all mold spores from wood where mold was previously found. It is unlikely that most construction materials, even when new, are free of mold spores, nor is”zero mold” a reasonable nor possible objective.

Cleaning moldy framing lumber followed by application of a sealant may be the most cost effective alternative . While lumber replacement with apparently “clean” new lumber may sound appealing, it is likely to be cost prohibitive and in fact may include its own mold when it is unloaded at the work site.

Cleaning Mold From Wood Trusses And Cross

In an area of high levels of mold growth or moldy dust and debris, the irregular surfaces formed by wood trusses and alsoby older wood cross bracing between floor joists prevents thorough cleaning of surfaces and creates many dust collectionpoints.

A similar construction detail where significant moldy dust reservoirs may be left in place is the upper surface of woodfurring which has been nailed across the under-side of floor joists to support ceiling tiles.

Because the surfaces formed by trusses and cross bracing can form a significant dust and debris reservoir, I always checkthese areas during a mold remediation clearance inspection. If work has been hasty or incomplete, these are among the firstareas to be under-cleaned.

Spray process cleaning, media blasting , and HEPA vacuuming are effective for these areas.

How To Remove Mold From Attic Sheathing

Depending on how large the area is, you might be better off leaving it to a professional than to do it yourself. Professionals have the right equipment and the right personal safety equipment to make sure they always stay safe. However, if the mold spread is small enough and manageable then here is what you can do. Before you undertake this DIY project, you must make sure that you are adequately protected and prepared by having the following items at hand. Without these items, continuing with your own DIY mold remediation project is highly discouraged!

  • Long-sleeve shirt
  • Pants that cover the entire leg
  • Closed shoes
  • Respirator mask
  • Air circulation at all times
  • Sponge
  • Plastic bag to dispose of the sheet
  • Borax
  • HEPA Vacuum
  • Dehumidifier

After you are all geared up and ready to go it is important that mold gets spread by microscopic particles called spores. To get rid of the spores and all the other debris close to the mold you want to use a vacuum with a HEPA filter. HEPA filters are used to get rid of microscopic particles that cannot be sucked out with a normal vacuum. It is specially designed to get rid of airborne allergens. Mold can be very dangerous and can cause serious complications.

Layout a plastic sheet or tarp that covers the whole work area

Turn on your dehumidifier while doing this. With a wet toothbrush, slowly and gently scrub away the mold of the sheathing/plywood. You will see particles of mold falling onto the tarp.

How To Get Rid Of Attic Mold With Tea Tree Oil

  • 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.
