What Are the Causes of Mold Found in Homes?

In order to prevent mold from growing in your home, you should know how it gets there in the first place. Here are the common causes of mold.

Finding mold on your bread can ruin your hopes of making a delicious sandwich. But finding mold in your home is far worse than a spoiled lunch. Mold causes damages your home so it's good to know tips to prevent mold growth.

Whether you are currently dealing with a mold problem or trying to prevent mold from growing, you should know the causes of mold and the signs to look for.

This article will identify the most common causes of mold in homes and how to fix it!


If you live in an area with high humidity or near a body of water you may notice signs of mold, especially in the hotter months of the year. Moisture in the air can cause mold to grow on the walls, ceiling, or inside dark spaces (closet, cabinets, etc.).

The best way to prevent mold in a humid environment is to ventilate your home. If you do see mold growing in your home, act quickly by calling a mold remediation company

Leaking Pipes

Mold found in homes is often caused by leaking pipes. Mold can grow behind walls or above the ceiling making it harder to detect. And by the time you do find the leak, the mold could already have spread.

If you suspect a leaking pipe, you can contact a plumber or water damage expert. Dry out the area and remove the mold before sealing.


If your home has recently flooded you could be looking at several types of mold growing within a matter of days. It's important to keep an eye out for mold growth while you are drying out the flooded area. Keep the affected area well ventilated too.

Leaking Roof

Much like leaking pipes, a leaking roof can cause mold growth - most often in the attic. When water leaks from the roof it provides the perfect moist environment for mold to grow and spread. Check your roof for leaks and keep your attic dry and well ventilated to avoid mold growth. 

Wet Clothes

Believe it or not, wet clothing that sits for too long can grow mold. Don't leave wet towels or clothes in a pile or for too long without drying them. If you don't have a dryer, consider using a clothesline outside to dry them and prevent mold.

Damp Basement

Basements are notorious for mold growth because they are often damp and humid. You may see signs of mold on the walls or the ceiling or notice a musty smell. You can prevent mold growth in the basement by keeping it well ventilated and as dry as possible.

Know the Causes of Mold and Stop the Spread

There are many causes of mold but most of them start with excessive moisture in areas of your home. You can stop mold from spreading by patching leaking pipes or the roof and keeping your house well ventilated.

Be aware of what mold looks and smells like so that you can take action quickly after finding evidence. And if you do find mold in your home, contact SERVPRO right away.
