Why Is There Mold on My Bathroom Ceiling?

Imagine taking a relaxing hot bath, only to look up and be greeted with dark spots on the bathroom ceiling. If these spots are circular-shaped and have a dark color like black, brown, or dark green, you probably have mold growing in your bathroom.

Time is of the essence when dealing with this fungus and stopping the infestation from spreading. If you spot it growing on the bathroom ceiling, it’s essential to remove it immediately. Leaving it unattended creates an unhealthy living space for everyone in the household.

What Causes Mold on a Bathroom Ceiling?

Mold thrives in moisture-filled, warm environments. Given the conditions that allow it to grow, it’s no surprise the bathroom ceiling makes the ideal breeding ground for mold spores. This fungus thrives in places where moisture has nowhere to go.

There can be multiple causes of mold growing on a bathroom ceiling. For example, steam from hot water rising to the ceiling can settle there, creating the perfect warm, damp environment for the spores to thrive.

Besides those activities in the bathroom that allow infestations to start, other issues can cause mold on bathroom ceilings. A pipe in the room above the bathroom that has burst or a roof leak can create water damage. Combined with the warm air rising from the bathroom, these cultivate the perfect place for spores to pop up.

Mold also grows in areas with poor ventilation. When the moisture remains for too long, spores start to form. And, as long as the moisture remains, they will continue to grow.

Not only are mold spores unsightly, but they’re also harmful. The Centers for Disease Control and Prevention shares that mold can cause health issues like coughing, throat irritation, eye irritation, or nasal stuffiness. More severe reactions include lung infections that can occur in those that have weak immune systems.

Structural issues also can result from mold damage. Unfortunately, homeowner’s insurance won’t always cover the cost of repairs.

The health risks and potential for structure damage make it crucial to remove the mold quickly, either by eradicating it yourself or calling in a mold removal expert.

How to Clean Mold From a Bathroom Ceiling

When mold exists in your home, you have two options: you can call in a mold removal expert, or you can clean it yourself. Here’s a step-by-step guide if you choose to remove the mold yourself.

1. Determine Whether It’s Mold

The first step to removing mold from your bathroom ceiling is determining whether it’s mold or dirt.

The most recognizable difference between the two is the smell. Dirt won’t smell like anything; mold has a distinct, pungent odor. Further, dirt will easily wipe off; mold won’t.

Here are signs you may have mold or mildew in your bathroom walls, ceiling, or shower:

  • Your bathroom lacks ventilation.
  • Your bathroom doesn’t dry completely.
  • You notice dark spots on the walls or ceiling.
  • Your bathroom is typically dark and damp.
  • Your bathroom smells musty.
  • You have allergic reactions to something in the home.

2. Gather Your Supplies

varied cleaning supplies

After you’ve determined there’s mold on the bathroom ceiling or walls, it’s time to take action. Start by gathering the following supplies:

  • Dish soap
  • Water
  • Bleach or white vinegar
  • Gloves
  • Eye goggles
  • Spray bottle
  • Sponge

Note: Before you move to the next step, put on your gloves and eye goggles.

3. Wash the Affected Area

Begin by washing the affected area with soapy water. Add warm water to a spray bottle and a few drops of dish soap. Spray the area and wipe away with a sponge. Let the area dry completely.

4. Kill the Mold

Now it’s time to bring out the bleach. Mix one part of bleach with three parts of water in a bucket or spray bottle. Using a heavy-duty sponge, scrub the affected area until the spots have disappeared.

When using bleach, remember three things:

  1. Open a window to allow fresh air to enter.
  2. Never mix any other cleaners or disinfectants with bleach.
  3. Always wear gloves and eye protection.

Prefer not to use bleach? Swap it out with white vinegar. Vinegar can also be effective and is a preferred solution in bleach-free homes.

To use, apply the vinegar to the affected area with a spray bottle and let it sit for an hour. Wipe it clean and let it dry completely.

5. Purchase a Dehumidifier

Once you’ve removed the black spots from your ceiling, you want to prevent the moisture from returning. If you don’t eliminate the root of the problem, this will turn into a recurring issue.

If your bathroom humidity levels are too high, we suggest you invest in a dehumidifier. It will lower the moisture present in the bathroom. To conserve electricity, set the dehumidifier on a timer.

If you purchase a dehumidifier, look for a model made specifically for bathrooms. These are electrical gadgets, meaning there’s always a fire risk if it gets wet. A bathroom-specific model means the wiring is concealed and sealed.

6. Clean Off Any Lingering Stains

Don’t be alarmed if your bathroom ceiling still has stains after removing the mold. Because bathroom ceilings are painted in light colors like white or beige, you’ll still be able to see where the mold once existed.

To fix it, you’ll need to paint over the unsightly stains. Just be sure you’ve successfully removed all traces of the fungus. Otherwise, it will grow underneath the paint and eventually poke through.

If you don’t eliminate the source of the issue, it will come back. In this case, if moisture persists in your bathroom, you can expect this fungus to return. Fortunately, you can do a few things to prevent it from growing on your bathroom ceiling:

  • Improve air circulation by opening a window or adding a circulating fan;
  • Clean the shower and tub regularly;
  • Dry your shower with a squeegee or towel after every use;
  • Wash shower curtains, towels, liners, and bath rugs regularly;
  • Invest in a dehumidifier and turn it on after you shower.
