Do you know where the most common places for mold growth are in your home? You may be surprised by what you find. Mold can grow everywhere, but some spots are better than others. Here are the most common places for mold growth in your home.


The bathroom is a very common place for mold to grow. It can grow behind the shower curtain, in the tile grout lines, and the caulk around the toilet’s base. The source of moisture that allows this growth may come from direct or indirect water contact within these areas. You may notice mold growing down your walls, under your sink, or behind your toilet. Make sure you check these areas and fix any leaks as soon as possible to prevent further mold growth.


The kitchen is another common place for mold to grow, usually around the sink and dishwasher. This is due to the moisture that these appliances create and the food scraps that can often fall into the sink. Mold can also grow in the grout lines and caulk around your countertops. Again, make sure you check these areas for any leaks and clean them regularly to prevent mold growth.

The dirtiest places in your kitchen are usually the ones with the most water exposure: under your dishwasher, beside your sink, and around your countertops. Mold thrives in moist environments like the kitchen, making the sink area a familiar spot for mold growth.


The basement is commonplace for mold to grow because it’s often dark and damp. Mold can grow on the walls, in the corners, and behind the furniture. It’s essential to keep your basement clean and dry to prevent mold growth.


The attic is another common place for mold growth, usually due to water leaks from the roof or air conditioning unit. This is because the roof and AC unit are traditionally some of the most significant areas in your house that can create water leaks. Pay special attention to these two spots, as well as any windows you may have in the attic to keep mold growth at bay.


The bedrooms are standard for mold growth if the humidity is left uncontrolled. Humidity can be high and cause mold issues in your house if you have water leaks or flooding problems. Mold will often grow on furniture and carpet, so pay attention to these areas as well as any windows in your bedroom to keep dampness under control.

Outside the House

Mold growth isn’t just a problem inside your house. If you have a shoddy roof or leaky windows, then mold can grow outside as well, causing problems for your landscaping and siding. Some people even find that their car is taking damage from the dampness of the mildew outdoors.

It’s essential to keep mold growth outside your house to a minimum. If you are in Illinois, Texas, Florida, or Wisconsin and you need mold eradication services, be sure to reach out to Pur360. This will keep your landscaping healthy and prevent damage to your siding.


Mold can grow anywhere that water is present, which means that your plumbing is a good place for it to take hold. If you have leaks in your pipes or see any wet spots on the ground around them, mold will grow there. It’s essential to take care of this problem as soon as possible before it begins to spread throughout your house.


Windowsills are common for mold to grow because they often have water contact. If you see any black or green spots on your windowsills, then it’s likely that mold is growing there. Be sure to clean these areas regularly and keep an eye out for any new growth.

Home Office

Mold can grow anywhere that water is present. Since your home office likely has a computer and other electronics, you may find mold growing on the keyboard or inside any cracks. It’s essential to clean these areas regularly to prevent mold growth.

To prevent mold growth in your home office, be sure to keep a clean workspace. If you live in a humid climate, it’s likely that you’ll find mold growing if your office is dirty and disorganized – especially on or around your computer. Clean your home office regularly to prevent mold growth.

Storage Areas

Many storage areas have issues with moisture, as they tend to be dark and damp. This makes them a perfect place for mold to grow if the area isn’t dry and clean. Storage areas house many different items, which means that mold can grow on anything from clothing to books if it isn’t kept clean. It’s essential to keep storage areas clean and dry in order to prevent mold growth.


Many homeowners neglect the stairs when it comes to cleaning and organization. This is because they are often underused or simply not seen by the homeowners. However, mold can grow on the stairs if they are dirty or humid. This is because humidity tends to gather in corners, which gives mold an ideal place to grow. Be sure to clean your stairs often and check for any signs of mold growth.

Laundry Room

The laundry room is a common place for mold growth because it’s damp and dark like your basement. If you have any leaking problems in your washing machine or dryer, you should routinely clean these areas. The lack of light makes this area challenging to keep an eye on, so it can be essential to pay attention to the floor’s cleanliness and ventilation.


The crawlspace is one of the most common places for mold growth. Since it’s often dark and damp, mold spores will thrive there if you don’t take control of the humidity in your home. It’s a good idea to have a well-ventilated crawlspace with dry ground, especially if you notice any discoloration on the walls or floor of the space.


You can control the humidity in your garage by opening the doors more often and using a dehumidifier when it’s incredibly moist. This will keep any mold from growing, so be sure to take these steps if you notice a problem.

Furnace Room

The furnace room is another common place for mold growth because it’s damp and dark. The humidity in a poorly ventilated furnace room can be extremely high, which is why you need to make sure that there’s a lot of airflow going through the area. If you see any black or green spots on the walls or floor, then it’s time to take some action.
