How To Check For Mold Inside Your Walls

  • Locate the center of the area most likely to have mold inside.
  • Shut off power to the area at the electric service panel.
  • With a pencil and straightedge, lightly mark a square approximately 6 inches by 6 inches.
  • Cut along the outline with a drywall jab saw.
  • Remove the cut-out and inspect its back for mold.
  • If there is no insulation in the wall, look at the back wall. Also, hold a small mirror inside and shine a flashlight on the mirror to inspect the back of the drywall.
  • If there is insulation, any mold on the drywall or studs will have spread to the insulation. So, the presence of mold on insulation usually means mold on other building materials.
  • How To Identify Mold On Walls

    Before you can start to remove molds from a wall, it is important that you identify all areas that have been contaminated. 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.

    Why Can’t Moldy Drywall Be Cleaned

    It is very difficult, usually impossible, to adequately remove mold from porous materials, and that includes drywall. Why? Well, porous materials aren’t entirely solid, even if they appear solid to the naked eye. Materials like drywall have very tiny holes, or pores, in them, much like the pores in your skin. Microscopic mold spores can remain unseen in the pores of the drywall, even when the drywall appears free of mold. It’s similar to the way dirt or oil can be trapped in the pores of your skin, even if you don’t see it.

    Much like how dirt or oil trapped unseen in the pores of your skin can lead to acne or other skin problems, unseen mold trapped in the pores of drywall can grow and spread and can also cause health problems. Since there is no effective way to remove mold from the pores of the drywall, the affected drywall must be removed and replaced.

    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.

    Inspect your interior hoses. You should replace flexible hoses on washing machines and kitchen sink sprayers immediately if you see a leak or condensation, and every five years, even if you dont spot problems. 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. Whether you find cracks 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 lead to water pooling near your foundation or along your walls, and that leads to water damage that causes mold.

    Remember, mold wont go away on its own. If you find signs of it growing on your walls, you need to take prompt action to get rid of it with these easy homemade mold-killing sprays. Then keep it from coming back by controlling your homes humidity levels, promoting good air circulation, and regularly cleaning to remove mold spores.

    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.

    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.

    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.

    How to Kill Mold Using Bleach

  • Use a ratio of 1 cup of bleach per gallon of water
  • Apply the solution to non-porous materials surfaces with mold growth with a spray bottle or by using a bucket and a sponge

    A home, cottage or cabin closed up for a while or exposed to moisture with little light or fresh air over time is likely to gather mold and mildew and smell musty. These problems do not pick one surface over another mold and mildew may affect walls, wood floors or even furniture. Getting rid of all the mold and mildew is the key to rendering the space comfortable, safe and free from odor once again. Enlist someone else to do the cleaning if you’re prone to allergies or asthma attacks triggered by either mold or mildew.

    Vinegar Can Prevent Mold Regrowth

    Vinegar is an effective cleaning solution for bathroom mold and mildew. Spray a wall with full-strength vinegar or a diluted mix of vinegar and water and scrub or wipe down at least once a week to discourage fungal growth. The presence of high levels of moisture, food sources, low air circulation and lighting levels in an area can make mold growth more likely.

    Taking measures to manage excessively high humidity or moisture levels can go a long way. If mold has grown on bathroom walls, make sure that the room has a functional ventilation fan with an airflow rating in cubic feet per minute that corresponds to the size of the space. Natural sunlight and artificial light also discourage mold growth.

    If mold continues to grow on surfaces, you may want to check for a more widespread infestation. Hidden mold may flourish behind walls and cause a problem to recur. Once a mold problem has been remediated, you can continue to spray on vinegar and wipe down walls once a week to discourage growth.

    Mold-resistant primers and paints can also prove effective for discouraging mold. Start by applying a coat of pigmented shellac or an oil-based primer. Once this preliminary layer dries, apply one or more coats of latex paint that contains mildewcide.
