What Causes Black Mold?

What causes black mold? There are several conditions that can lead to the growth of black mold. Understanding the causes of black mold will help you to prevent these conditions and potentially avoid the problems that occur with black mold growth.

All types of mold, especially black mold, thrives in frequently damp areas, such as baths, showers, toilets, kitchens, and basements. Damp areas are not the only locations that mold can grow on, places like wood, dirt, or even on paper.

Many situations or places in your home can be reasons that black mold grows, for example:

Leaks

When your home has any kind of leak, it can create enough moisture for black mold to start to grow in that location. Due to many leaks being minor or even in areas that are not easy to see, it can be easy for leaks to go undetected for a long time. Many times by the time a leak is noticed, you already have black mold growing. The main location that you can find a leak in pipes, roofs, air conditioners, toilets, and washing machines.

Condensation

Condensation occurs when warm air and a cold surface meet. Things like pipes, air conditioners, walls, or anywhere that condensation can occur, are all areas where black mold can grow. One main concern when it comes to condensation is that it can even accumulate on concrete, even if it is underneath the carpet. Because of this, it can be very hard to spot.

Poor Ventilation

Since it is very common for modern homes to be tightly sealed, making it easier to heat and cool the home. However, this also causes the house to have poor ventilation. Poor ventilation is an issue because it can make it difficult for humidity to escape the house which causes the moisture to attach to the ceilings and walls. Due to the lack of airflow, the wet areas can take longer to dry, giving black mold more time to grow.

Blocked Gutters

The purpose of gutters is to keep the away rainwater from your home, when gutters are blocked the rainwater cannot escape. If blocked gutters go unnoticed or is not fixed, it can cause water to build up within the gutters resulting in the water to begin to enter your home by seeping into walls, foundation or through your roof. The water entering your home creates the perfect spot for black mold to begin growing.

Overall, it is best to be diligent in trying to prevent black mold from growing and from potentially needing to get professional mold removal done in your home. There are many steps you can take to help reduce the what causes black mold to grow in your home. The easiest way is to control the moisture that within your home, you can do this by adding fans and ventilators anywhere you can.

Another important step in reducing the chance of mold is to check your house for any leaks, and if you do find one it is important to deal with the leak as fast as possible. Spots to check for are places such as any pipes under the sink, or the toilet bowl. Leaks can happen in just about any location around your home.

  • I recently discovered a mild mold problem in my crawlspace and begin my search for a company to remediate. Fresh Air Tech. seemed to have the best treatment plan for my situation and was the most competitive when it came down to the price. I had the mold removed/sprayed with prevention chemicals, crawlspace cleaned with a new vapor barrier and a dehumidifier installed. I didn't know what to expect never having to deal with this before but I can ensure you these guys do not cut corners and did an excellent job. The cleaning crew (3 guys) arrived about 8AM and were under the house until about 4:45PM cleaning and sanding taking a quick 30 minute lunch break around noon. They returned the next day to install the vapor barrier and to finish cleaning up. The dehumidifier also comes with a monitor that displays the temp and moisture level down in the crawlspace which i thought was pretty cool. Excellent job, thanks again team.
