Dealing With Mold In Walls
Before beginning the job of removing mold from the inside of walls, you need to cover doorways, air vents, and other openings to other parts of the home with plastic. If youre working in a large room, you can use large sheets of plastic to block off a smaller area in which you will be working. This prevents the spread of mold spores to other areas of the home. Mold remediation experts often recommend setting up negative pressure in the work area, as well.
Remove moldy drywall and insulation. Use a spray bottle of water to dampen moldy materials before removing them this helps prevent mold spores from becoming airborne during the process. When sawing through moldy drywall, you can have an assistant hold a vacuum hose with a HEPA filter nearby to further decrease the spread of mold spores. Enclose moldy materials in heavy plastic garbage bags before carrying it out of the home so no mold spores are spread to other areas of the home in the process. Its imperative that you do everything possible to prevent spreading mold spores throughout the house so that you dont end up with mold in other rooms.
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.

Where Youll Find It Growing
Mold on your basement or exterior walls occurs when water vapor in the air meets a cold surface and turns the vapor into a liquid. Bathrooms and laundry rooms develop mold because theyre typically very humid. Other humid areas include the walls and ceiling near humidifiers and any room with a hot tub or jacuzzi improperly installed indoors.
Mold also grows where there is a water leak. Places like the cupboards under sinks are prone to mold. Once a pipe has leaked, theres a good chance mold will grow unnoticed within the wall until the problem requires expert removal.

Types Of Basement Mold
Various types of mold will infest your basement. While they are all hideous, not all of them are toxic to humans.
Molds can be divided into two categories:
- Allergenic
- Mycotoxin/black
Allergenic molds usually pose no health risk unless you are extremely sensitive to molds or asthmatic. Black molds, on the other hand, produce a toxic chemical called mycotoxins and are particularly harmful to humans and pets.
Here are the common types of molds that can infest your basement.
Aspergillus
Aspergillus is one of the most common household mold species. There are different types of Aspergillus, and most of them thrive well indoors. Some of the Aspergillus molds are allergenic, but some are mycotoxin and should be removed by a specialist, especially if it is something like black mold.
This fungus is dark green and found on damp walls, ceilings, and even furniture. It flourishes in humid environments, but can also grow in areas that are dry with high levels of humidity or condensation.

If you can visibly see that you have a problem, it typically means it has been there for a long period of time, because it has time to grow and spread in an area large enough to be visible. It generally grows on porous materials, such as wood, drywall, fabric and carpets however, it can also grow on non-porous materials such as tile. It needs the right conditions to grow. There has usually been some type of water damage and the area has stayed wet long enough for the spores to grow.

If you dont replace them on time, your homeowners or renters insurance wont pay if they burst and cause water damage. Inspect your roof after storms. Look for loose shingles or other damage that could allow water to enter your attic or home. Keep your foundation clear. Dont stack firewood or other items against your homes foundation, or youll encourage water collection there that will seep into your basement walls.
Fix cracks promptly. If you find gaps in your foundation or siding, fix them immediately to keep water out of your home. Clean your gutters in the Spring and Fall. Clogged gutters cause water to pool near your foundation, leading to water damage that causes mold.

The first sign that you have mold in your basement is the unpleasant musty, almost earthy smell in your basement. It is similar to the wet wood smell. Once you notice the smell, look around places where mold appears.
Mold develops around pipes and vents, in the ceiling, around the dryer, and as it starts growing, it can overtake the wall. Mold will generally make the area look dirty and speckle sections with black dots or spread in irregular shapes. It can start in dark corners and work its way around to the wall and ceiling.
Mix The Mold Cleaning Solution
In a plastic bucket, mix one-part dishwashing liquid, 10 parts bleach, and 20 parts water. To clean a small area of mold, mix a solution of one tablespoon dishwashing liquid, 1/2 cup chlorine bleach, and one cup of warm water in a spray bottle. The dishwashing liquid helps the solution cling to the wall longer to kill the mold spores.

Why Does Mold Grow In The Inside Corners Of Walls
There are two possible causes for a mold problem at the inside corners of exterior walls. The first is poor air circulation. Warm air registers are normally located in front of windows so they can blow warm, dry air over the glass to cut down on condensation. Corners that are located away from this moving air, like those in closets, become cool and allow moisture to condense. The moisture is what mold and mildew thrive on. The second is uninsulated framing cavities. During cold weather, the inside wall surface cools, moisture condenses, and mildew sets up shop.
