How To Treat Mold In Basement

Use Alcohol Or Vodka For Fragile Materials

What Is Efflorescence? | White Mold or Something Else?

Rubbing alcohol or vodka are also mold killers. Using either ingredient is ideal if youre cleaning mold from fragile materials. Spray the alcohol directly onto the surface or use a clean cloth to apply the alcohol and scrub the surface. Rubbing alcohol kills the mold. However, it does not prevent future growth.

Of Hard Deposits On Inside Of Concrete Blocks It’s Only On The Lower 1

This is a tricky one. If its hard to the touch, its not mold. Its either mortar or efflorescence. The latter will dissolve in water. Typically its powdery, but Ive seen it form hard, crystal like deposits in some cases. The fact you found mold on the backside of the sheet rock points to an ongoing moisture intrusion. This would explain the efflorescence, which occur when moisture moves through masonry. I recommend testing the deposits by submersing them in water. Do not reinstall the sheet rock until youve dealt with the underlying moisture issue.

Why Basements Are Problematic

Basements are prone to musty odors and mold growth. This isnt surprising. If you dig a giant hole in rain soaked dirt, the water will quickly fill the cavity. We really shouldnt be surprised when water enters our basements instead, we ought be amazed it doesnt happen every week. In the Pacific Northwest, a basement is essentially a concrete boat attempting to float in a muddy pond It can work, but we shouldnt be startled by the challenge.

Moisture wants to move from areas of high concentration to low concentration. If the soil surround your home is wet and your basement is not, the laws of physics are compelling the water to enter your home.

    Black mold can also take over the basement floor. It can be caused by leaking pipes, poor drainage or lack of ventilation. To eliminate it, fill a spray bottle with water and spray the floor, then scrub the floor with a stick scrub brush as much as possible. Then, mix water with ammonia in a bucket, and use a scrub brush to clean the floor. Once done, use water to remove all the remaining soapy water from it. Next, prepare a mix of bleach with water and scrub again. Leave the bleach for several minutes and then clean again with plain water to remove the bleach. Dry the floor ensuring to remove all moisture from it. Finally, use a dehumidifier to keep the area moisture free.

    Install An Hvac Ultraviolet Light

    When the entire black mold removal process is finished , then installing an HVAC UV light is highly advisable.

    Here is an article I wrote on my best picks for HVAC UV lights to kill mold.

    An HVAC UV light is a special type of light bulb that is installed inside your furnace, and it shines 24-hours to kill and prevent mold growth. The UV light shines a special light frequency known as UV-C that has been proven to kill mold organisms.

    It actually disrupts their cellular DNA. Hospitals have been using UV lights for years to sanitize operating rooms.

    How To Clean Mold From Wood

    Mold loves wooden surfaces. Whether its your window sills, flooring, wall framing, or furniture, the high cellulose content of wood provides mold with lots of food. Because wood is also very absorbent, its easy to create a perfect environment for mold with very little moisture. If you do find mold growing on wood in your house, heres how to get rid of it.

    Youll need:

    100-grit sandpaper


    Step 1: Begin by vacuuming up as much of the mold as possible using a vacuum with a HEPA filter. You can also use a soft-bristled brush to dislodge the mold and make this easier. Remember to wear a dust mask to prevent breathing in mold spores while you do this.

    Step 2: Add a teaspoon of soap to two cups of water in a spray bottle. Shake to combine and spray the mold and surrounding surface.

    Step 3: Use a soft-bristled brush to scrub away the mold and mildew. Use paper towels to soak up any excess water.

    Step 4: To kill the roots, add 1 tablespoon of borax to a cup of water and use a soft-bristled brush to apply the solution to the area. Allow it to absorb into the wood.

    Step 5: Run a fan or dehumidifier in the room to quickly dry the wood.

    Step 6: If the mold is very stubborn, use 100-grit sandpaper to remove the affected area.

    Pro Tip: Is the wood still stained? This is usually a result of mildew the discoloration mold leaves behind. While bleach doesnt kill mildew, it can help remove the stains. Try scrubbing a small area with a dilute bleach solution.

    Another very important factor for the formation of mould is the relative humidity in the room. First of all: what information is hidden behind the term relative humidity?

    The air can only absorb a certain amount of water vapour, and this amount depends on the temperature. A cubic meter of air at a temperature of 0 degrees Celsius, for example, can absorb 5 grams of water vapor. The amount increases with temperature, and so a cubic meter of air at 30 degrees Celsius can already absorb 30 grams of water vapor.

    The relative humidity always refers to the percentage of air load . If there is 30 grams of water in one cubic meter of air at 30 degrees Celsius, then the relative humidity is 100%. For 15 grams of water 50% accordingly. When the air is saturated, the gaseous state of the water cannot be maintained and drops of liquid are formed. This condensation, but also relative humidity values of over 70%, favour mould extremely, from 80% it is practically unavoidable.

    The exact values shown in the following table should be observed for the individual rooms.

    dtd> 40% 60%


    You need a hygrometer to measure relative humidity. This allows you to read the relative humidity in the living rooms at any time.

    Basement Mold Prevention Strategies

    Yes, the sheet rock should be removed. This is necessary not only to clean up the existing mold, but to implement the prevention measures.

    First, you need to identify the source of the moisture. Three possibilities exist. 1.) Condensation from the warm interior air hitting the cold concrete wall. This typically does not happen behind a well sealed wall , but its possible.

    2.) Vapor emissions through the concrete. This occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface. In an uncovered wall, the water would simply evaporate into the air without causing an issue. The installation of the sheet rock traps the moisture, leading to mold growth. There are two solutions either keep the concrete exposed or install dimple board with a interior footing drain.

    3.) Liquid water intrusion. Its possible youre having liquid water enter through the cold joint at the bottom of the wall. If this is the case, youll see more damage at the bottom plate/framing than higher up the studs. In most cases, the solution is an interior footing drain.

    Causes Of Mold In The Basement

    Understanding how and why mold found its way into your basement is vital. You dont want to waste time getting rid of it only for it to reoccur.

    Lets briefly delve into the science behind mold. Your unwanted home invader is the result of fungi species that generate spores to reproduce.

    When these teeny-tiny spores, invisible to the naked eye, land on something wet, they start to grow. Theres no way for mold to thrive and survive without moisture .

    Now that youre versed in mold 101, you can likely anticipate what the causes would be. These are the reasons why your basement could have been affected:

    • After flooding: A flooded basement is an optimal environment for mold. Standing water and damp items such as furniture and carpets can serve as breeding grounds.
    • Water leaks: As with post-flood moisture, leaky pipes, appliances or drains in your basement will increase your risk of finding a moldy surprise.
    • High humidity: If the old stereotype of your basement as a damp and dank place applies, your chances of mold will be higher. Humidifiers, air vents and similar steamy gadgets or mechanisms can all encourage mold.

    Common Causes Of Mold In The Basement

    As mentioned above, the main cause of mold in the basement is excess moisture, which is not a rare situation in a basement. Whether that moisture comes from the outside or from the inside, it is very important to get to the root of the problem in order to deal with it and prevent any further complications .

    So, where does the moisture, or water in a basement come from? Lets dig deeper.

    There are two main sources of water in basements:

  • An outside moisture source rain, groundwater, floods.
  • An inside moisture source a high level of humidity and different activities such as drying clothes.
  • Basements are below grade spaces in your home, which means that they are prone to water seeping in from the foundation walls, and window wells. Since these are the lowest parts of the home, gravity dictates that if water is present, it will flow towards the lowest area to settle.

    Two frequent causes of water in basements are rain and floods. Without proper grading, gutters and downspouts, rain often flows into the basement creating excess moisture for mold to thrive in. Flooding caused by heavy rains or rivers, provides the right environment for mold growth.

    When it comes to sources of moisture inside, we can talk about various causes, from ineffective insulation to excess steam that evaporates and raises the level of humidity . A high level of humidity and condensation creates the perfect conditions for both mold and mildew to spread in your basement.
