Purchase a relative humidity gauge and install it in the basement. Your goal is to keep the RH below 50%. Increase the heat as necessary to lower the RH until youve reached 50%.

The easiest way to increase the ventilation is to run a bathroom exhaust fan. If theres an existing fan in the basement, run it at least 12 hours per day in the winter months.

Its also important to verify whether the basement is suffering from vapor emissions through the concrete slab. This occurs when water vapor moves up through the slab and into the room above. If the basement is carpeted, the moisture can become trapped and lead to mold growth. See our page on basement mold for more info.

Concrete walls present slightly different concerns.

Unfortunately, basements usually have plenty of dust to keep them well-fed and reproducing. They also present a sizable obstacle to removing existing infestations.

In a standard mold removal operation, the contaminated materials are removed and replaced with fresh ones. Concrete makes that difficult since you cant just take out a portion of the houses foundation. That doesnt mean that mold cant be removed from concrete walls, but rather that it is a job best left to professional mold removal experts.

To clean mold off concrete, begin by cleaning the concrete surface with a hose, removing as much black mold as possible. If the concrete is located indoors, use a sponge to scrub away the mold. A scraper is also an effective tool for removing the mold from concrete.

Keep in mind that though these methods are effective, physically scrubbing or scraping the mold away will not remove the root, which is embedded inside the porous concrete. If the root is still intact, the mold will simply grow back.

Killing mold beneath the concretes surface requires cleaners that can penetrate the concrete. While bleach is effective and kills mold, its surface tension does not make it ideal for soaking concrete. Laundry detergent is a better option.

Create a cleaning solution by mixing a cup of laundry detergent with a gallon of water. Use a sponge or brush to apply the solution to the floor. The detergent will soak into the concretes pores, killing the black molds roots.

Use a scrub brush to ensure the solution penetrates the concrete and to remove the molds roots. When complete, rinse off the concrete with clean water. If outdoors, use a hose. If inside, use a mop.

Repeat this process if any mold is still present. Dry the concrete with a fan until it is completely dry.

    The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.

    If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.

    What Is The Best Product To Remove Mold From Walls

    There are multiple products on the market to remove mold, and some are more effective than others. A popular pick is RMR Complete Mold Killer and Disinfectant. Its EPA-registered formula works to kill mold, clean stains and eliminate odors in one simple step. It also serves as a household disinfectant that can kill bacteria and virus particles so that you can find other uses for any leftover product.

    Homeowners should always use caution when selecting a product since they may require special protective equipment or ventilation support. Also, some are specifically designed for outdoor mold problems and should not be used in indoor areas. That is especially true of basements, which often have low ceilings and a lack of natural ventilation.

    Some families choose a more natural solution, which can also be effective. For example, high-potency vinegar can effectively kill mold even deep inside of porous materials like your basement walls. However, its high acidity can damage some surfaces, making it a poor choice for removing mold on waxed wood, natural stone, waxed wood, aluminum or cast iron.

    Why Does Mold Grow On Basement Walls

    When mold is provided with a dependable food source and adequate moisture, it will begin to feed and reproduce. The most dependable food source for mold is cellulose. It is found in wood and paper-based materials that are abundant in homes.

    It also requires high moisture content to grow. Some types, such as Stachybotrys chartarum , require a constant water source, while others can thrive with occasional moisture or high humidity levels. Basements tend to have poor ventilation, allowing humidity or dampness from the surrounding soil to accumulate inside. Coupled with the cellulose found in drywall, insulation backing and dust, this is an ideal environment for mold growth.

    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.

    Avoid Overloading Your Basement

    Both an organic food source and moisture are important for mold to grow. Thats why its very important to cut the food source, along with lowering the humidity level in your basement. There is no better food for mold than the things you keep in your basement such as clothes, books, carpets, food and even the cardboard boxes in which you store all of those things.

    Try eliminating everything that you dont need and avoid overstuffing your basement at all costs. Air must be able to flow and it cannot do so if every inch of your basement is covered. If you must use your basement for storage, and you are worried about mold, ensure that everything is properly dried and moved away from the walls. If there is a leak or a flood, take out everything that may have been in touch with water, dry it well and then put it back.

    Black Mold On Concrete In Basement

    How to Get Rid of Mold from Basement Easily

    For black mold on concrete in a basement, start by ventilating the area well. Because youll be using bleach indoors, open a window and escape the fumes when possible. Create a cleaning solution thats one part bleach to four parts water and apply it to the concrete. Allow this solution to sit for fifteen minutes before using a wire scrub brush to clean the mold off the surface. Make sure you leave the area while the bleach is soaking to prevent breathing in fumes. Its important to wear protective gear during this process, including rubber gloves and a respirator. After youve scrubbed the area, soak up the cleaning solution and apply clean water. Scrub once more and remove all surface water. Allow the area to dry completely. If your basement area is relatively damp, use a fan to dry the floor quickly.

    Our Flooded Storage Unit

    If youve been a long-time follower, you may remember this blog post where I chronicled our first flooding experience. Back then, we were living in a small condo and we rented an off-site storage unit to hold our childhood boxes, Christmas decor, my wedding dress, and more. During an extremely cold winter season, a pipe burst at the storage facility, and all of our items were submerged in feet of water. It was pretty horrendous.

    That was a very emotional experience for us both. I had just suffered a miscarriage and I was still recovering, physically and emotionally, and it hit us when we were already down. And seeing all of our memories from our lives ruined, was very difficult. But, we got through it and my mom was even able to salvage my wedding dress from the wreckage. Jan saves the day!

    After that, a lot of good, big things happened for us. We bought this housewe finally had success with IVF and then our sweet rainbow baby, Rory, was here about a year later. It was the start of a lot of good for us. So, Im looking at this flood as potentially the start of good things for the Finn family.
