Tips To Remove Mold From The Walls
ServiceMaster Disaster Associates, Inc.Mold Removal
Mold is a naturally occurring substance and its spores can always be found in the air. It does not become a problem until the spores have encountered the proper environment, triggering mold growth.
To grow, mold needs two things: a food source and a moisture source. When mold spores find both, mold will begin to grow. The need for moisture is also why mold growth is so common in the aftermath of water damage.
Because of this, mold commonly grows in damp areas of your home, including bathrooms and kitchens. Simply bathing or showering can make a bathroom damp enough to encourage mold growth. This can cause mold to appear on walls, tiled or not.
When mold has grown in your home, such as on your propertys walls, you should address the situation immediately. If mold has more time to grow, it will cause more problems. Mold eats away at the building materials it grows on, ruining their structure, and can result in health problems to those individuals exposed to it. Because of this, you need to remove any mold growth right away.

How To Get Rid Of Basement Mold
There are numerous ways to get rid of mold in your home and basement. However, before you start clearing out the mold, make sure you fix the real problem as the mold growth is only a symptom of an underlying problem. This could mean fixing a leak, ensuring that the basement has proper ventilation, and checking that any standing water has dried.
Here are several methods you can use to remove mold from your home and basement.
How To Get Rid Of Mold On Walls
Many people first notice theyve got a mold problem when they see it growing on their walls. Check in the corners near the ceiling and floors in rooms with high moisture levels, such as kitchens, bathrooms, laundry rooms, and basements.
Step 1: Make a solution of one part bleach to three parts water in the spray bottle.
Step 2: Saturate the mold and surrounding area on the wall.
Step 3: Let the solution soak into the mold for 10-15 minutes.
Step 4: Using the scrubbing brush, remove the mold and stains.
Step 5: Repeat as necessary to remove all the traces of mold and mildew.
Step 6: Make a 50/50 mixture of white vinegar and hydrogen peroxide in the second spray bottle.
Step 7: Spray the cleaned surface and allow it to absorb and air dry.
This method works because it addresses the visible mold, as well as the underlying roots that often go untreated. Surprisingly, vinegar and hydrogen peroxide are both more effective at killing mold roots than bleach. Because they work best on different types of mold, try to use them together to cover all the possible varieties of mold you might be dealing with.
Pro Tip: If you dont have hydrogen peroxide at hand, you can also clean mold with vinegar and baking soda instead.

Does Vinegar Kill Black Mold
Vinegar can kill up to 80% of mold varieties, including Stachybotrys chartarum, or black mold. For greater effectiveness, consider mixing together a solution of vinegar, water and a powder-based antifungal or abrasive cleaner, such as Borax or baking soda, both of which are sold at grocery and home improvement stores.
How Do You Check For Mold Inside Your Walls
To check inside your walls for mold, you’ll need to carefully cut out six-inch squares of drywall, remove the cut-out squares, and use a long-handled mirror and flashlight to look inside for mold. It is recommended that you check in several places, since you might miss small amounts of mold if you only look inside the wall in one spot. The U.S. Environmental Protection Agency recommends hiring a professional to help you look for hidden mold, including mold in walls, since the process can potentially spread mold throughout the room and expose you to harmful mold spores, if in fact it turns out there is mold inside the wall.
