The inside of your walls is a great environment for mold, but a terrible one for you to find and clean. Often homeowners dont realize there is mold inside their walls until its causing a major problem. Warning signs include an earthy, musty odor in the home, allergy symptoms that clear up when you leave the property, and stains or dampness on the wall itself. If mold does get inside your walls, youll probably need a pro to handle it. At the very least, the drywall has to come down in order to properly access and treat the mold and prevent it from coming back.

How To Prevent Attic Mold

Mold Removal

There’s one good way you can avoid cleaning up attic mold entirely: Preventing it in the first place. With a little hard work and diligence, you can ensure that mold can’t find a home in your house.

First things first: Good attic ventilation is key to preventing mold. Make sure none of your vents are blocked or closed, including your gable vents, your vents along the eaves , and your vents along the ridge of the roof. The airflow keeps moist air moving and out of your attic.

Additionally, double-check that no hot, moist airlike air from a dryeris venting into your attic, as this is another easy way to make a home for mold.

If you live in an especially moist and damp area, consider installing an attic vent fan, which provides extra protection against moisture.

Another preventative measure to take against attic mold is to spray a mold barrier in your attic, which prevents mold growth on surfaces. Finally, inspect your attic seasonally so that if you do find mold, you’ll find it before it spreads.

“A periodic look around and a sniff in the attic will save you from mold spores affecting your health and paying to remediate an infestation,” Leduc says.

Tip 11 Check Your Bathroom Paint

Because steam is the most common cause of bathroom ceiling mold, there are two things to check. One, if your bathroom ceiling is insulated, check how close the insulation is to the edges. Most builders stop the insulation about 6 inches from the crown molding. This causes cold spots at the ceiling edges, which is why mold gathers on those spots. Use a thermal camera to confirm.

The camera will identify cold spots so you can buff up the insulation on those bare spots. Second, be careful about the ceiling paint you select. Matte paint absorbs more water, so it could aggravate your mold problem. Glossy paint or exterior weather-proof paint works best. You can also apply ceiling paint thats infused with anti-mildew ingredients like mildewcide.

Does Attic Mold Affect Indoor Air Quality

Given all these precautions for attic mold, you might be wondering why it can be so hard to notice until its too late. Part of that is because attic mold doesnt necessarily affect the quality of air inside your home.

This is due to the simple fact that warm air rises, a phenomenon known as the stack effect, in which air rises from the lower levels of your home to the attic. Since mold spores dont have wings as in they cant fly against the upward flow of the stack effect within a house its extremely rare for attic mold to affect the indoor air quality.

However, attic mold is a common issue that homeowners dont know they have until other issues arise. Although there are plenty of professionals that can remove attic mold, its also better to prevent it from happening in the first place, even if it doesnt directly affect the air in your house.

How To Remove Mold From The Roof And Ceiling After It Rains

How to Clean Up Attic Mold | This Old House

· Updated 05/11/2022

Rainy days and humidity contribute to mold growth on the roof and ceiling, especially when a home is riddled with undiscovered leaks. Mold is a pervasive fungus and will colonize ceilings and rooftops that remain damp. Heres how to remove mold from these areas after a downpour.

Fierce storms may loosen rooftop shingles. Loose shingles will, over time, be vulnerable to high winds. As wind gusts lift the shingles, rainwater has the opportunity to seep underneath them. A cracked, weakened roof develops gradually, eventually leading to leaks that enter the interior parts of the home.

A roof leak will prompt a homeowner to immediately begin rooftop repairs. While the roof will be fixed right away, a savvy homeowner should also be on the lookout for mold growth along the roof and ceiling. The EPA confirms that a leaky roof can lead to a mold infestation.

Mold colonies have the potential to multiply on rooftop areas where moisture cannot escape. When air is unable to reach and dry rooftop crevices, moisture becomes trapped. In places that remain damp, mold begins to grow. In fact, mold develops within 24 to 48 hours after prolonged water exposure.

A few dark splotches along the roof or the ceiling underneath may seem harmless. However, mold colonies are far from benign. Mold growth weakens structural materials, leads to rot, and eventually disintegrates the home. The homes occupants can also suffer from mold allergy symptoms.

How To Get Rid Of Mold In Your Attic

There is a straightforward fix to getting rid of mold in your attic. That is, seal your ceiling.

You can use spray foam to seal all the tiny cracks in your ceilings. Just be sure you are purchasing the right spray foam, it should be fire-rated and for insulating.

These cracks, as mentioned above, could be from light fixtures, drywall junctions, attic ventilation, plumbing stacks, anything that goes into your attic and penetrates your ceiling.

Pro Tip: An easy way to find the areas of concern is to go where the mold is. So, if the mold is on the roof decking, the air is probably leaking right below that area.

Another Pro Tip: If you have a thermal camera you can see where air is leaking by scanning the ceiling for hot spots. These are areas where there is poor insulation.

A word of caution: Only do this if you are handy and understand how to walk in an attic. You could fall through the ceiling!

What Happens If I Dont Remove The Mold In The Attic

The attic mold is the effect of attic condensation . Over the years mold will decompose the roof sheeting from the inside causing undulation on wood and premature shingle wear. Most roofers when replacing shingles describe it as softness of wood as they walk since they can not see the mold growth on opposite side of sheeting. Its hard to sell or get insurance to any home that contains mould, our advice is to remove it sooner than later.

Causes Of Mold In The Attic

Is this mold on roof sheathing

water damage and excessive moisture causes mold and this is no different in the attic. Most of the time, condensation occurs in your attic due to ventilation issues which in turn causes leaks and moisture. This causes mildew, wood rot and interior water damage. Over time, mold grows and if left untreated, it becomes a big problem if not dealt with.

The image below illustrates the problem on the right, with the ideal house on the left.

Every house was built with a specific roof ventilation calculation to ensure adequate air ventilation. Some times, home owners will add new house features such as installing bathroom exhaust vents or upgrading the insulation. These changes will effect the air circulation and create the moisture for attic mold to start rotting your roof sheeting.

Mold Removal From Fabric

Its easier than you might think for clothes to attract mold and mildew. A forgotten load of laundry in the washing machine, the pile of clothes at the bottom of a closet, or even the armchair in a humid room can all quickly become overrun with mold. However as long as you catch the problem early, your fabrics can still be saved.

Bleachable fabrics

If you can apply bleach to a fabric without worrying about discoloration, do it. Thats the fastest and most effective way of getting rid of mold. Many laundry bleaches can be used on white and colorfast fabrics, although you should always check the instructions, and never use bleach on wool or silk. Simply apply a solution of one part bleach to three parts water and let it absorb into the fabric for a few minutes before laundering as usual.

Non-bleachable fabrics

For fabrics that cant be bleached, use white vinegar instead. Either apply white vinegar to a cotton pad and place it on top of the stain for five minutes before laundering, or briefly soak in a solution of ¼ cup vinegar to one gallon water. Rinse through to remove the vinegar and launder as normal.

    • A sore throat
    • Itchy skin and eyes
    • Lethargy

    These common symptoms may simply be from allergies or a cold, but if they last longer than two weeks, they may be due to untreated mold.

    Seal Moldy Areas After They Dry

    • Set out dehumidifiers and new fans to dry the now-cleaned areas for at least three days, then check them by sight and smell for mold.
    • Pro tip: If you discover more mold, clean again with bleach for mold remediation.
  • When youre sure the mold has been eliminated, seal the wood surfaces with pigmented shellac like BIN or an oil-based primer like KILZ.
  • Repaint cleaned wall surfaces with a regular latex paint that contains a mildewcide to help stop future mold growth.
  • Install new insulation and drywall and nail the trim back on. Keep in mind that if the moisture returns, mold will return.
  • Tips For Mold Prevention

    After you learn how to remove mold, focus on preventing it in the future. Controlling dampness is the key to stopping most mold. The worst infestations usually occur in damp crawl spaces, attics, walls where water leaked in from the outside, and in basements with poor foundation drainage. Stopping leaks, ensuring good ventilation in attics, keeping crawl spaces dry and routing water away from the foundation are the best defenses against mold.

    Mildewcide in paint is usually effective for controlling surface mold in damp rooms like bathrooms, and outside in shady areas. Many paints already have mildewcide in them. Check with your paint dealer about mold removal products.

    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.
