    How do molds grow on walls? And why?<\/strong><\/h2>\n\n\n\n

    Certain things make mold grow on walls. Several factors are responsible for it. It accelerates the growth process of these molds.<\/p>\n\n\n\n

    • Humidity: This is the primary cause of mold problems inside homes. If you live in a humid area, it is advisable to purchase a dehumidifier and move it regularly to different parts of your home to decrease moisture content in your indoor air.<\/li><\/ul>\n\n\n\n
      • Condensation: This occurs naturally in the perimeter walls of your home, which is cooler than the air inside your house. When the water in the air experiences a temperature drop as it touches the walls, condensation takes place (moisture is turned into liquid).<\/li><\/ul>\n\n\n\n
        • Water leaks: Another common cause of black mold in walls are water leaks coming from different sources, such as holes in the roof or cracks on plumbing systems. It is important to check pipes regularly and takes steps to keep them from leaking.<\/li><\/ul>\n\n\n\n
          • Water in the foundation: Look out for a build-up of water around your home\u2019s base. This can lead to foundational problems for your home if there is a lot of water. At your home\u2019s foundation, gathering rainwater can be prevented by sloping your yard outwards from your foundation. In the same line of thought, damp basements are another culprit. Usually, there is no good ventilation in basements. This is an indication that basements could contain higher humidity or moisture amounts compared to other rooms in the home. Also, basements are often colder which means more condensation occurs which leads to humidity and basement.<\/li><\/ul>\n\n\n\n
            • Flooding:<\/strong> Flooding is another cause of mold. Problems with mold removal problems are hard to avoid if your home has gone through a flood. Your home will be wet and it may take some time before your home becomes dry. It could take weeks to dry your home. This means that there is a great risk for the growth of mold. Remember that mold only needs twenty-four hours before growth occurs.<\/li><\/ul>\n\n\n\n

              What are the other types of mold on walls?<\/strong><\/h2>\n\n\n\n

              Removing black mold behind drywall is a serious task.<\/p>\n\n\n\n


              But you should know that aside from black mold in walls, other types of mold could grow on the surfaces or even inside walls. They include Aspergillus (which can cause allergic reactions and respiratory infections), aureobasidium (which can cause more severe reactions than black mold on walls), Chaetomium, Penicillium, and Serpula Lacrymans (that can also grow on wood surfaces).<\/p>\n\n\n\n

              What are the signs of mold growth?<\/strong><\/h2>\n\n\n\n

              A lot of the time, detecting mold just means you need to throw out an old sandwich. However, extensive mold in the home can become dangerous. The reason is that some species of mold produce mycotoxin, a substance that leads to headaches, problems with breathing, and even damage to the neurological system. Other symptoms may even include an annoying odor, sneezing, or a runny nose. There are other more subtle signs your home has mold.<\/p>\n\n\n\n


              For one, a nasty smell coming from your heating system or air conditioner can mean mold. In particular, stand-alone units of air conditioning are the main spots for the growth of mold. They are dark, damp, and exposed frequently to warmer temperatures when not in use. Putting an air conditioner in a heated closet or basement during wintertime also leads to an increased likelihood of the development of mold.<\/p>\n\n\n\n

              When there is mold inside your walls, you won\u2019t be able to tell how extensive the damage is on your own. Removing mold from inside your walls may even be dangerous, particularly if you are suffering from existing conditions such as:<\/p>\n\n\n\n

              • Allergies<\/li>
              • Asthma<\/li>
              • Breathing problems<\/li>
              • Skin irritation<\/li>
              • Itchiness<\/li>
              • Fatigue<\/li><\/ul>\n\n\n\n

                Unless you are a licensed mold expert, it is best to leave the mold eradication process to a team of professionals. Doing this yourself may aggravate your symptoms and any pre-existing conditions unnecessarily. Attempting to do anything yourself may even cause you to spend more money later on trying to deal with your aggravated symptoms that are a direct result of mold.<\/p>\n
