Remove Mold From Plaster Walls
Under the right conditions, plaster can absorb a large amount of water and if the water is allowed to sit, black mold may appear. Cleaning a plaster wall will help to temporarily remove the problem, but to prevent the risk of it returning and/or spreading, itâs best to improve the air circulation with a fan or install a dehumidifier.
How To Inspect For Mold Growth In Your Home
Its important to regularly inspect your home for mold growth. Most molds may appear gray, white or black, and they grow in damp areas of the basement with poor air circulation. They may appear as a thick, velvety fungus, or they may look like dusty blotches on the drywall. Water seepage and flooding may cause mold to grow, often in dark corners, along baseboards and inside cupboards. Use a flashlight to inspect the area beneath sinks where a slow drip from the plumbing provides the perfect spot for mold spores to reproduce. Move furniture to examine the walls and the floor beneath, and lift acoustical tile in a drop ceiling to examine the space above. Speckles of gray or white mold on drywall may indicate a larger mold problem in the stud space behind the drywall.
Removing Mold From Different Rooms
Some rooms are more prone to mold than others. Bathrooms are notorious for mold growth because they harbor damp, humid environments that mold loves. Less frequented rooms such as basements and attics can also suffer from mold, which can go unchecked for a long time before being noticed. Heres how to prevent mold from taking hold in each room of your property.

Mold Removal Using Bleach
Bleach kills virtually every species of indoor mold that it comes into contact with including mold spores which leaves a sanitized surface making it resistant to future mold growth. However, bleach is only effective if the mold is growing on non-porous materials such as tiles, bathrubs, glass and countertops.
Bleach is unable to penetrate into porous materials such as wood and drywall which means it cannot get rid of mold growing beneath the surface of these materials. If you use bleach to kill mold on these surfaces it will only kill the mold above the surface. It will be unable to reach the mold within the material and the mold will soon return.
Bleach is a harsh, corrosive chemical which means it can damage the materials it is used on. It also gives off harsh fumes and produces toxic gases when mixed with ammonia. There are safer alternatives such as borax or vinegar which dont produce the dangerous fumes or leave behind toxic residue.

But that is rare, and in the vast majority of cases the wood is still strong and structurally sound.
The good news is that black mold on wood can almost always be easily removed.

When To Contact Mold Cleaning Experts
The most cost-effective method of getting rid of mold is the approach to cleaning that will kill growth and stop spores from spreading. Ineffectual treatments that allow mold growth to continue in treated or hidden locations can end up costing a lot more in the long run.
A good way to reduce or avoid mold remediation expenses is to fully repair water damage in a timely manner. If this damage has already occurred, the most important factor is the extent of an infestation and the type of mold that seems to be present.
Infestations that affect an area larger than 10 square feet may require limited or full containment and the cleaning and containment expertise of trained mold remediation professions. This is also the case with mold that seems to be the cause of allergenic or toxigenic effects on the occupants of a structure.
It is impossible to identify the species of mold based on appearance alone. Depending on the situation, mold remediation professionals may recommend testing to determine whether the mold is toxic. In other cases, mold testing may be recommended to ensure that removal is complete.
Porous materials that are infested with toxic mold may prove difficult or impossible to clean. In some cases, mold may start growing behind drywall or on insulation, in which case it may be necessary to tear out and replace these materials to solve a mold problem.
Household Cleaning Solutions Are Affordable
Whether you prefer to use standard 5% strength distilled white vinegar, 6% cleaning vinegar, baking soda, Borax or hydrogen peroxide, all of these cleaning solutions are affordable and likely to be in your home already. These ingredients are also available for sale at most grocery and home improvement stores.
If mold is growing on a non-porous surface, you can use a surface disinfectant like bleach or vinegar. While the costs may be comparable, the effects of cleaning walls with these solutions may result in a need to repaint or refinish walls sooner rather than later.
Stubborn mold infestations may call for the use of heavy-duty fungicides or mildewcides. Make sure to use mold killing products that are for the intended application. If you are not sure about the extent of an infestation or whether the mold is toxigenic, consider contacting certified mold removal professionals to inspect or test mold and recommend the most effective approach to remediation.

The most common areas where it is found typically include the basement, bathroom, kitchen, garage and bedroom, especially a bedroom that is next to a bathroom or a bedroom next to the laundry room. You should look in areas that have a lot of dampness or moisture, such as the laundry room, basement and kitchen. You should also look at the grout between the bathroom tiles, above ceiling tiles that water stains, in any area where you smell mildew or there is a musty smell and any area that has been subjected to flooding. If you have water stains on the wall, or peeling or bubbling paint, it may be inside of the wall, which means you may need to remove the drywall to look behind it, especially if you smell a musty odor. Identifying black mold is fairly easy, because it is as the name suggests, black in color. It also usually has a slimy appearance.
