Mold in a garage is fairly unusual. Are you seeing mold on the ceiling or somewhere else? What region of the country are you located in?

If the mold is on the garage door, its due to condensation from excess humidity in the winter. Installing a low-CFM constant flow bath fan in the exterior wall will solve the problem.

If the mold is on the ceiling, I recommend investigating it as a roof leak. Mold due to condensation is very unusual in the garage because there is typically no moisture source .

What Do Professionals Use To Kill Bathroom Mold

As far as the experts go, you can expect your local mold removal service to use commercial-grade cleaners. They may employ mold-specific products or all-purpose chemicals that can handle mold as well as bacteria, viruses and other microbes. If your mold problem is especially widespread, they may even use mold bombs, which are cleaning solutions that slow-release from an aerosol can to cover a large area. Youre likely to see professionals use cleaners that contain bleach in the bathroom if the mold is growing on nonporous metal or tile, but they may use less harsh products if the mold is growing on the wall or ceiling.

Handling mold can feel like a hassle, but it can be done. When dealing with a mold outbreak in your home, safety should be the number one priority at all times. Any time youre around mold, especially while treating it, you should be wearing a face mask and protective gloves for your hands. If you start to notice symptoms like coughing, sneezing, chest tightness, watery eyes or a rash after working with mold, stop and take a break. These symptoms are usually temporary reactions that will go away in a day or so, but you should keep an eye on them and hold off on cleaning until you feel well enough to get back into it. If your symptoms persist or worsen, you should stay out of the mold-infested part of the house and speak with your doctor.

Based on your description, this certainly sounds like humidity/condensation based mold growth. You need to lower the humidity levels in your home.

Causes Of Mold Growth On Drywall

How To Remove Black Mold From Your Bathroom Ceiling

No matter where it springs up, mould is caused by one thing: moisture. The moisture may come from a flood, leaking water or even high humidity in a home. Unfortunately, mould on drywall is usually due to a more serious problem, as opposed to a simply leaky faucet. Because of this the problem may be larger than you can handle and its very possible that professionals will need to be consulted. Some of the most common reasons for mold on drywall include a leaking window, a flood in the basement, or leaking from an upstairs bathroom. Always start the assessment by determining the exact cause of the mold on your drywall.

Hi We Are Meant To Be Moving Home Soon When We Viewed The House In October We Noticed A Leak And They Said They Would Have Someone Out To Fix The Issue Asap The Leak Was Coming From The Toilet And The Water Had Spread To The Ceiling Below Now In February We Have Gone Back And The Leak Has Only Just Been Fixed And The Flooring Was Still Wet There Is Now Mould Growing In The Area On The Ceiling Downstairs What Are Our Options Is It Likely The Drywall And The Structural Supports Need Replacing Thank You

Yes, the ceiling should be removed. The framing behind it is likely intact. It takes quite a bit of sustained saturation to structurally compromise a floor joist. The mold growth can look quite bad and yet not affect the strength of the wood. Youll know if the wood is compromised it will crumble or deteriorate by simply poking it with a screw driver.

The Pros And Cons Of Using Hydrogen Peroxide On Mold

Hydrogen peroxide is about as effective on mold as bleach.

The problem is that it can even cause white paint to fade or alter its color.

Before you clean a wall with this option, youll want to spot test a surface that is out of sight to make sure your drywall wont be affected.

Youll want a 3% solution that you can apply directly to the mold, so thats good news because thats the solution youll find at most department stores.

Spray the hydrogen peroxide onto the mold directly and then allow the surface to sit for at least 10 minutes.

Scrub the area to remove the mold and then wipe it down to remove any residual mess.

Repeat as necessary to remove any lingering mold.

Use Borax To Scrub Away The Mold

Borax has a higher pH than baking soda or vinegar, which makes it the best option for killing mold. Youll want to use 1 cup of Borax for every gallon of water you use.

Take a vacuum and remove as much freestanding mold as you can.

Then scrub the mold with your Borax solution until the signs of it disappear from the drywall. Wipe away any excess moisture and allow the drywall to then dry.

Dont rinse off the mixture.

Vinegar is an even safer option, but it only kills about 80% of household molds that may form.

It may be non-toxic, but it may also be ineffective.

If you do use vinegar or baking soda, make sure you leave your preferred cleaner on the mold for several minutes before scrubbing it away to achieve best results.

Youll then want to apply vinegar on the affected drywall every few days for a couple months to make sure no spores decide they want to grow.

Remove Mold From Drywall/painted Walls

Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.

I recommend renting or buying a moisture meter. This is the only way to conclusively determine if you have a leak. Based on the location of the mold/wet spot, you likely have a very slight leak from the toilet seal. This is quite common. Due to the limited size of the damage, I would not recommend removing the ceiling. Instead, replace the toilet seal and monitor for future leaks.

Dealing With Mold On Drywall

As we just said, since mold cannot be completely removed from drywall, the drywall must be removed and replaced. This must be done with care because cutting into moldy drywall causes mold spores to become airborne and spread.

The U.S. Environmental Protection Agency advises that if mold covers more than 10 square feet, a professional remediation company should be hired to remove the mold. If it is a smaller job that you plan to handle yourself and you have any health concerns, speak with your doctor to make sure it is safe for you.

First the work area must be prepared. Furniture and other items should be removed from the area if possible. Otherwise, they should be covered securely with sheets of heavy plastic to protect them from mold spores.

Plastic sheets should be taped over heating and air conditioning vents to prevent mold spores from entering your heating, ventilation and air conditioning system. Hi-hats hould also be covered with plastic.

The floor should also be covered with large sheets of plastic, to prevent the flooring from becoming contaminated with mold.

First the drywall should be sprayed with water to prevent mold spores from becoming airborne as the drywall is taken down. The moldy pieces of drywall should be enclosed in heavy plastic trash bags before you carry them through the house, so as to prevent scattering mold spores as you go.
