Mold can grow in your home if there are leaks. Roof or plumbing deficiencies also give the perfect environment for mold to thrive, so it’s important that these be fixed as soon as possible!

2. Poor ventilation, often caused by closed windows and doors

Many homes are not adequately ventilated, which can lead to mold growth. Especially in homes that are not often vacant. The most common causes of this problem include keeping your hvac higher than 77+ degrees combined with the windows and/or doors not being opened at least once a week for some fresh air!

3. Humidity levels that are too high

The most common cause of mold in homes is excessive humidity(between 40% and 60%)

Molds can create an environment where they thrive by producing spores, which will continue growing if left unchecked until the conditions become less suitable or there are no more food sources available.

4. Flooding or water damage

To prevent this problem for good; make sure there isn’t any standing water inside by taking care of leakages around pipes or any other point of water intrusion into the home.

5. Presence of pests, such as cockroaches or rodents

The presence of pests is one thing that can cause mold. Cockroaches and rats especially like living in homes with hidden water sources, which might be ornate toilets or kitchens where they go unnoticed until it’s too late!


Mold is a serious issue that can lead to devastating health consequences. It’s important for homeowners and renters alike to be aware of the five most common causes so they can take steps, such as installing a dehumidifier or performing regular maintenance on their home, in order to reduce mold growth.
