I really think the fan is not hooked up to vent. Just laying in the ceiling venting into the attic. The attic also might have mold too.

Willing to bet that the fan is not connected to any duct work and is dumping moisture above the ceiling.

Does that fan work?

If that’s the bathroom it should be getting the moisture out and through the attic to the outside.

That indeed looks like mold build up around the openings.

Spray bleach & don’t wipe. Air out the room. Check the exhaust fan’s filter to see it needs to be replaced.

When’s the last time the cover was removed from the fan and the housing was cleaned out? Lint and dust can build up in there, trapping moisture and reducing airflow

1. Yes

2. Spray bleach and wipe down

3. Only if it’s seeped down into the drywall itself. If its only surface and the bleach gets rid of it, you should be good.

Same thing

It looks like the moisture was trying to escape via the vents. You may be able to hit it with some mold spray and see if that takes it away and a repaint. If it’s not dry you will have to remove that drywall and replace. Clean that fan too.

Bleach kinda kills mold, but reach for the Germicidal Bleach for this.

It looks surface and should wipe off after you let it soak in the bleach to kill the mold.

That’s probably surface mould you can clean off, if the gypsum is wet replace the drywall. This is an attic and there is either no insulation around this fan or there is air leaking and the vapour barrier needs to be sealed around the fan. The lack of insulation makes the surface cold, cold surface plus moist air equals condensation, condensation causes mould growth. Clean it, add insulation and seal around and on the attic side with plastic vapor barrier and acoustic sealant or spray foam(under the insulation)

im sure the restroom has a moldy smell at this point. I recently dealt with something similar due to a leak in the roof. Got the leak repaired and ended up replacing the damaged drywall in the ceiling since the damage was minimal.

Figure out the source of the dampness.

Take off the fan cover and see if the fan is working, and make sure it is blowing outside.

Go on the roof and ensure the output isn’t clogged with something.

Then definitely try to clean the surface first.

Another poster suggested “germicidal” bleach.

This sounds like a great place to start.

You have to fix the problem before cleaning it.

It will just happen again.

The Unwelcome Guest: Mold and Mildew in Your Bathroom

When it comes to maintaining a clean and hygienic bathroom, there are several factors to consider. From regular cleaning to proper ventilation, it’s essential to create an environment that discourages the growth of unwanted microorganisms. Unfortunately, mold and mildew are two common culprits that can quickly take over your bathroom, posing health risks and unpleasant odors. In this article, we’ll delve into the world of mold and mildew, exploring their causes, effects, and most importantly, how to prevent and eliminate them from your bathroom.

What is Mold and Mildew?

Mold and mildew are both types of fungi that thrive in damp, humid environments. While they may seem similar, they have distinct characteristics. Mold is a type of fungus that grows in long, branching strands, often appearing as black or greenish-black spots. Mildew, on the other hand, is a type of fungus that grows in a powdery or fuzzy coating, typically appearing as white or grayish patches.

Causes of Mold and Mildew in Bathrooms

Bathrooms are the perfect breeding ground for mold and mildew due to the following factors:

  1. High Humidity: Bathrooms are prone to high humidity levels, especially after showers or baths. This creates an ideal environment for mold and mildew to grow.
  2. Poor Ventilation: Inadequate ventilation can lead to a buildup of moisture, which fosters the growth of mold and mildew.
  3. Leaky Fixtures: Leaks from faucets, toilets, or showers can create a constant source of moisture, attracting mold and mildew.
  4. Dirty Surfaces: Failure to clean and disinfect bathroom surfaces regularly can provide a food source for mold and mildew.
  5. Lack of Sunlight: Bathrooms with limited natural light are more susceptible to mold and mildew growth.

Effects of Mold and Mildew in Bathrooms

The presence of mold and mildew in your bathroom can have serious consequences:

  1. Health Risks: Inhaling mold spores can exacerbate respiratory issues, such as asthma, and even trigger allergic reactions.
  2. Unpleasant Odors: Mold and mildew can produce strong, unpleasant odors that linger in the bathroom and even spread to other areas of the home.
  3. Property Damage: Left unchecked, mold and mildew can cause significant damage to bathroom surfaces, including tile, grout, and drywall.
  4. Reduced Property Value: The presence of mold and mildew can negatively impact the value of your property.

Prevention and Elimination Strategies

To prevent and eliminate mold and mildew from your bathroom, follow these steps:

  1. Improve Ventilation: Ensure proper ventilation by installing exhaust fans or upgrading to more efficient models.
  2. Clean Regularly: Clean bathroom surfaces regularly with a solution of bleach and water to prevent the growth of mold and mildew.
  3. Fix Leaks: Address any leaks promptly to prevent moisture buildup.
  4. Dry Surfaces: Dry bathroom surfaces thoroughly after cleaning to prevent moisture accumulation.
  5. Use Mold-Resistant Products: Consider using mold-resistant products, such as paint or caulk, to reduce the risk of mold and mildew growth.
  6. Increase Natural Light: Consider installing skylights or larger windows to increase natural light in your bathroom.

Conclusion

Mold and mildew are unwanted guests that can quickly take over your bathroom, posing health risks and unpleasant odors. By understanding the causes, effects, and prevention strategies, you can create a clean, hygienic, and mold-free bathroom environment. Remember to prioritize regular cleaning, proper ventilation, and prompt leak repair to keep your bathroom mold- and mildew-free.

Hello! I spotted this in my guest bathroom and I have a few questions:

1) does this look like mold or mildew?

2) I already had my handyman check the attic space and all for damage. No damage. No water. With that in mind, is this something I can clean up?

3) does the dry wall need to be replaced?
