Can Bathroom Mold Cause Illness

How to Prevent and Remove Bathroom Ceiling Mildew

For the most part, mold just looks bad. For some, it can irritate allergies and asthma.

Mold is relatively harmless, but given the right circumstances it can definitely cause some irritation, Tolliver said. If you have pre-existing allergies or COPD or some sort of respiratory condition, the spores can actually irritate the lining of your lungs and can increase your risk of asthma attacks or COPD exacerbation.

People who are affected by bathroom mold will most likely experience runny noses, coughing and scratchy throats.

Ogden noted that people with allergies should be tested for which specific allergens bother them so they can best protect themselves. Mold is one of the irritants that can be identified through allergy tests.

Doctors can and should identify what the culprit is, she said.

Over-the-counter treatments can frequently ease the feeling associated with an allergy attack, but more severe cases could require a doctors intervention.

Minor adjustments can keep mildew and mold in check to prevent potential allergies.

Cleansers with bleach, or even white vinegar, can often keep the slimy, hairy growths from taking root in the bathroom. Wearing gloves and a mask can protect people from inhaling any mold spores as they scour the bathroom surfaces.

These are some expert-approved steps to stop mold from colonizing the bathroom in the first place:

Why Is There Mold Around The Air Conditioning Vents

Friday, September 21, 2018

The louvered metal grille that directs conditioned air from a duct into the room is called a register, and mold around an air conditioning register can have several causes:

1) If the cold air coming out of the register is too cold compared to the room air, condensate will form on the surface of the register and migrate over to the surrounding drywall. Wet drywall will begin to grow mold within a few days. The register in a bathroom is more likely to have mold growth because the high humidity in the room provides more moisture for condensation.

;; The difference between the room air and cold air coming out of the register is called the temperature differential or split, and more than about a 22º F split can cause condensate to form.;

2) Duct air leakage above the register or at the connection of the duct to the register can also cause condensate to form, even if the temperature split is not excessive, because the air in the unconditioned attic or wall cavity may be significantly warmer. If squirrels or rodents get into the attic, they may ;shred openings in ducts for material to make their nests. Workmen in the attic also occasionally cause duct damage that leads to leakage.

;; Home inspectors like us that have an infrared camera are able to detect duct connection leakage before it causes ceiling problems. The cold areas show up as blue in the bottom photo below of a leaking register connection to duct.

Double-check to ensure all the mold is gone before you remove the visible evidence. Youll have to sand off the stains, apply chemical treatments, or paint over those unsightly marks.

How To Remove Mold From Drywall

Removing mold from drywall can be tricky because if drywall gets too wet, it is ruined. In fact, its often easier to cut out the infected section of drywall and replace it, rather than trying to treat the mold directly. If the drywall feels soft, its beyond saving. However if you do want to clean the drywall without removing it, heres what to do.

Youll need:


Step 1: Brush the mold off the drywall using the scrubbing brush. Try to remove as much as possible without getting the wall wet.

Step 2: Make a 50/50 solution of white vinegar and hydrogen peroxide. Spray it onto the area until it is damp, but not soaked.

Step 3: Wait 10 minutes then use a medium-bristled brush to clean the wall using circular motions. Dont scrub too hard or youll damage the drywall.

Step 4: Wipe down the wall using household disinfectant wipes.

Step 5: Allow the wall to dry. In high-humidity environments, set up a box fan directed toward the wall to dry it as quickly as possible.

If the drywall is stained when dry, use a primer or stain block before repainting. Consider a mold-resistant paint to provide extra protection, and reduce humidity in the room to stop mold from returning.

Hi I’ve Been Having Problems With One Of My Upstairs Bedrooms There Has Been Multiple Yellow Drips Above The Window A Week Later They Turn To Mould Clean It Off With Mould Spray And The Same Thing Happens Again Insulation Has Been Fitted In The Past Few Months But It Is Still Occurring

Was it occurring before the insulation was installed? There are a couple of potential causes. Often the insulation is pulled back from the soffits to allow for proper air flow. This creates a cold spot in the last 6 or so inches where the ceiling meets the exterior walls. If a home has elevated humidity , condensation and mold growth can occur. Running the bathroom exhaust fan throughout the day can greatly reduce the relative humidity in the home. Also, ensure the insulation contractor placed insulation as close the edge as possible . A scan with a thermal imaging camera will readily show whether this is occurring. Youll see an obvious blue spot in the exact location of the moisture and mold growth.

The other possibility is a roof leak or gutter issue. If you live in a snowy, cold climate, ice damning can also cause an issue like this.

Tips For Mold On Your Bathroom Ceiling

Mold can be a pretty scary thing. It looks horrible on a white ceiling so its easy to panic when you spot it. In reality, mold spores are everywhere. Its a type of fungus, so if your ceiling is moist, these floating spores will attach and start to grow.

Ceiling mold is mostly black, but it can also be white, green, gray, or even purple. And its a common problem for bathrooms because theres so much moisture. So while you cant avoid getting your bathroom wet, lets look at some tips to deal with mold on your bathroom ceiling.

Tackling The Underlying Cause Of Mold

Molds are all around us we breathe in their spores every day. Its impossible to prevent mold from entering any property, but steps can be taken to stop mold from finding a new home in your house. Without addressing the underlying cause of why mold is growing in a particular area, it will just keep coming back.

Molds only need two things, food and damp. Its impossible to remove the food mold needs from your home, because your property is made of it. Particle board, gypsum, wooden framing, and soft furnishings can all nourish and sustain large mold colonies. What you can control, however, is damp. When mold is discovered, look for the underlying source of water.

There are three common ways that water can cause problem mold growths:

  • Maintenance issues such as leaking pipes or failed window seals
  • Human error, for example not drying water in shower door tracks or splashing water around a sink
  • Construction-related, usually relating to ongoing condensation issues caused by poor airflow

The first two are easy to resolve. Simply repair the problem or change your habits to be more conscious of where water is splashing and pooling. If mold is growing because of the construction of your property, it may require more extensive intervention. Installing fans or vents, replacing portable heaters, or investing in a dehumidifier might be necessary to resolve the problem.

Taking Care Of The Grout

Cracked grout is the perfect surface for mold to grow on, and its often the place where you can spot it easily. Replacing your shower grout every 6 months is the most important step you can take to keep mold out of your bathroom. Its best to clean your tiles and grout once a week with a pH-neutral cleaner, to prevent mold from invading and developing.

Each time you change the grout, make sure to seal it with a latex penetrating sealer. The pores in the grout will absorb it, which will provide protection from mold. While it is true that some of these sealers can be expensive, a choice of high-quality sealer will keep your grout mold-free longer than the 6 months we mention above.
