Common Causes for Mold in Your Home

Mold is a simple organism, as it needs only a few things to not only survive but thrive. When your home becomes flooded due to a plumbing emergency, leaking roof, or natural disaster, those primary criteria for mold growth are usually in place. Mold requires moisture and darkness to begin rapid growth and proliferation, and in the days after a residential flooding event, those factors are present. Whenever your residence experiences water damage, mold in LaGrange can be a problem that must be corrected by a professional water restoration company.

Aside from the few examples mentioned above, there are many ways that mold can begin its rapid growth in your home once moisture is introduced. While there are some moisture sources that come by way of exterior damage or plumbing problems, there are other more benign moisture issues that can result in mold in the dark corners of your residence. Keep reading to learn about some of the common causes of mold in the home.

Plumbing Problems

By nature, your plumbing brings water into your home. However, it’s supposed to remain in the pipes instead of leaking out into walls, crawlspaces, and attics. Plumbing leaks are a primary cause of mold growth in many structures because small leaks can go undetected for long periods, providing mold with the time and dampness needed to become widespread.

Roof Leaks

Your roof keeps water out of your home under most circumstances, but even a minor roof leak can lead to the development of mold in infrequently visited areas of the home. When water leaks into the attic, it creates an environment in which mold can thrive. Without remediation of the leak and the impacted structural materials, it can spread through the entire home quickly.

Natural Disaster

Flooding associated with natural disasters isn’t just dangerous in the moment but can lead to dangerous mold growth in structures that aren’t properly remediated following the flooding event. Flooding can occur as a result of swollen rivers or powerful storms such as hurricanes. Whether flooding is the result of the steady rise of a nearby river or pounding tidal surge from a tropical storm, the result is the introduction of water into the home. Because drying takes time, mold can use that window of opportunity to take hold and begin its lifecycle.

Excess Humidity

In damp and humid climates, surfaces stay moist unless there is an HVAC system or dehumidifier in place to pull the water vapor from the air. That dynamic is magnified when there’s inadequate ventilation to help move moist air out of the structure regularly. When structures don’t have such a system in place, that excess humidity leads to dampness in walls, ceilings, and flooring. That can provide a suitable habitat for mold growth to take hold, and unless the air is dried consistently, it can grow rapidly once it starts.


Though many people associate mold growth with warm weather, it can also develop during winter months, especially in the setting of the home. In the winter, cold temperatures outside and warm interior climates can result in significant condensation on and around windows. That moisture can provide the needed element for mold growth to begin, and unless steps are taken to dry the area, it can quickly become a problem.

Damp Basement

Thanks to its design and location, the basement beneath your home can become a common source of moisture that can percolate into your home. The basement is a low point, and as such, acts as a natural drain point for any water that may leak inside. Because it’s at least partially subterranean, it usually doesn’t have good ventilation, which can further prevent drying. The surrounding soil on the outside of the walls also compounds the problem, so it’s difficult to regulate moisture in the basement even under the best circumstances.

If you’ve experienced any of these episodic or continuing exposures to moisture in the home, it’s a good idea to have a water restoration company conduct a mold inspection in LaGrange. An inspection will not only help detect mold in the home, but it will also help you identify the source and possible solutions to the problem.
