Ideal Conditions for Growth

Before we start going into where does mold most commonly grow in homes, you first need to understand why mold even grows in homes in the first place.  

Mold grows in places with high humidity which basically is the measure of the amount of water vapor in the air. Higher humidity = wetter air. This means that mold is highly dependent on water. However, it is not the only important factor. 

Temperature plays a big role in this as well. Mold does not grow in cold places. This is one of the main reasons we put our food in the fridge instead of just leaving it in the room. The ideal temperature for mold growth is approximately anywhere between 77 and 86 degrees Fahrenheit (25-30 Celsius). 

Lastly, rich plant life helps mold growth immensely.  

Do these three sound familiar?

They definitely do if you live in Sarasota or anywhere in Florida. The state has the ideal conditions for mold growth and this is why so many people living in FL struggle with mold problems.

Signs of Mold Presence in Home

Besides obvious visible signs of mold, there are other things you should look out for. Mold usually lurks in the dark and it can’t be always spotted but there are some other signs that give it up.

You may start sneezing and feeling dizzy more often. Being exposed to mold usually leads to these types of symptoms. It feels like a cold that never seems to go away. 

Places in Home You Should Inspect

Let’s go over the places in homes where mold presence is the most common. 


It’s obvious, right? In the bathroom, we use a shower, washbasin, and toilet. In other words, there is a lot of water flowing through our bathroom every day. And without proper ventilation, sooner or later, there will be some mold problems in your bathroom. 

The most common sign is black mold between tiles. This is what most people experience and the good news is, if you’re not experiencing other signs of severe mold infestation like feelings of cold and allergic reactions, there isn’t a lot of it and you can remove it by yourself with some wiping and brushing. But this all depends on the amount of mold present. 

If you sense that you have a bigger problem, you should consult with a professional. 


The Bathroom and kitchen are the most common places for mold growth where we spend a good portion of our days. In the kitchen, mold is often present around taps due to moisture but it can also find itself in not-so-easy-to-spot places like behind cabinets and other kitchen furniture. 


Unlike in bathroom or kitchen, you don’t spend a lot of time in your basement and attic. The reason why mold is usually found there is because there is no ventilation and water leaks often happen without you noticing at first. 

On what kind of surface does mold mostly grow?

Mold grows on the material it can eat. In other words, any organic material. Frequent ones include:

  • Wood (often roof)
  • Cardboard
  • Wallpaper
  • Drywall

On the other hand, you may experience a small problem that doesn’t have to be dealt with by a professional. Instead, you can remove the mold yourself with some inexpensive cleaners and a bit of work. 

Just know that mold is often hiding so what looks like a small problem can often be bigger than it seems. It’s important that you consult with a family member to hear their thoughts on your issue and then decide what to do next. If you have a friend or an acquaintance that is a bit more educated on the topic, consult with them as well.
