Top Causes of Mold Growth in Houses

High Humidity Levels

The first thing to consider is that mold growth is tightly connected to humidity, so most reasons mentioned below will be somewhat related to moisture. This is because mold thrives in moist environments, so high humidity levels in a home can create the ideal conditions for mold growth. Humidity levels in a home should be kept below 50% to prevent mold growth.


Mold grows best in warm environments with temperatures between 40°F and 100°F. This is why mold is often found in damp, warm areas such as basements, attics, and bathrooms.

Water Leaks

Water leaks, such as from a leaky roof or plumbing, can provide a source of moisture for mold to grow. Address water leaks promptly to prevent mold growth.

No Air Flow

Poor ventilation can result in high humidity levels and increased moisture in a home, which can result in an environment that's prone to mold growth. Improving ventilation, such as by installing exhaust fans or simply opening windows and doors, can help prevent mold growth.

Poor Air Quality

Poor air quality can also contribute to seeing black spots all over your ceiling, such as air that is contaminated with mold spores or spores from other sources.


Flooding can result in significant water damage to a home which, as you can imagine, is conducive to mold development. It's key to fix any water damage promptly and to thoroughly dry out a home after a flood to prevent nasty fungi.

Shoddy Building Materials

Certain building materials, such as drywall and insulation, can absorb moisture and provide a source of nutrition for mold to grow. It's imperative that you use mold-resistant building materials, such as treated lumber. Also, don't forget to get rid of water damage for your family's and property's sake.

Subpar Construction Practices

Poor construction practices, such as insufficient insulation and improper sealing, can lead to moisture buildup and mold growth.

A Damp Basement

Damp basements can be just what mold needs to grow uncontrollably, especially if there is poor ventilation in the basement. It's crucial to take care of any water leaks or dampness in a basement promptly to get rid of the consequences of mold growth.

Ineffective Drainage

Poor drainage around a home can result in water buildup and high humidity levels. By now, it should be no surprise that these are the exact conditions mold needs to thrive. It's essential to ensure good drainage around a home, so you don't have to look at another black spot ever again.

Over-Watered Plants

Over-watering plants, or having plants in areas of a home with poor ventilation, can result in high humidity levels and create the ideal conditions for mold growth.

Organic Materials

Mold grows on organic materials such as wood, paper, food, and fabric. These materials provide a source for mold, allowing it to grow and spread.

Lack of Maintenance

Finally, if you don't do a good job of maintaining the place, you will see mold growth. Lack of maintenance, such as not cleaning gutters and downspouts or having a dirty house, will all cooperate to guarantee that mold will grow in your home.
