How Long Does It Take for Mold to Grow?
One of the most frustrating problems to have to deal with around the home is a leak. Leaks present immediate problems, such as damaging your things.
They can also lead to staining and discoloration of your floors, ceiling, and walls. But one of the scariest dangers is the mold that could crop up later if you leave the area untreated.
But, of course, it’s not just a leak that could invite mold into your home.
Mold could also pop up for many other reasons, such as humidity, leaks, condensation, poor ventilation, wet clothing, and a damp foundation.
But, how long does it take for mold to grow on certain surfaces and become visible? Check out the table below to find out and learn how quickly it can start showing spores:
|Location of the Mold||How Long It Takes for the Mold to Grow||How Long It Takes for the Mold Spores to Become Visible|
|Hidden Surfaces||24 to 48 hours||24 hours|
|Hard Surfaces||24 to 48 hours||14 to 21 days|

4 Areas in Your Home Where Mold Grows The Most & Tips to Prevent It
Now that you know how long it takes for mold to grow, it’s time for us to take a look at the rooms that mold is most likely to affect.
This guide will also give you some simple solutions to help prevent the build-up of mold in the home.
#1 The Bathroom
It is common for mold to grow around the shower and bathtub, under the sink, on the walls and floor, and behind the toilet.
A very minor leak in the pipes under the bathroom sink could attract mold. A cupboard under the bathroom sink could also begin to harbor mold. It could do so if cleaning equipment isn’t dried properly before it is stored under the sink.
Mold can also find its way between tile grouting on the floor and walls around the shower and bathtub.
Luckily, you can easily prevent mold from appearing in your bathroom by fixing leaking faucets and pipes, drying surfaces after cleaning them (such as the floor after mopping), and installing an extractor fan.
#2 The Kitchen
The kitchen has a variety of surfaces. Some of its surfaces are warm and wet, such as the area near the sink. The kitchen is also made up of hard areas and open spaces, such as the tiling and floor.
This makes it easy for mold to grow in some parts of the kitchen and harder for it to grow in others.
It is common for mold to grow in the kitchen under or around the sink, in the refrigerator, or in the microwave.
You see, mold can quickly spread around the sink because it is always damp and spores usually begin to grow in the place where you leave your wet sponge. It is also common to find them under, around, and on your drying rack.
Moreover, food that has passed its use-by date is also likely to grow mold. This can quickly spread, even if the food is kept inside the fridge. Food that is left out in the open is also a target for mold. This is especially true if it is left in a warm, enclosed space such as the microwave.
Don’t worry, though. You can easily avoid this situation from happening by fixing leaking faucets and pipes, drying countertops after cleaning them, and removing old food from the refrigerator. Moreover, cleaning spills in the microwave immediately, drying the dishes, and installing an extractor hood could also help.
#3 The Bedroom
Condensation can also cause mold spores to grow.
You see, condensation is caused when humid air meets a cold surface like your windows. This is why it’s recommended to clear condensation off the windows to prevent the issue.
Moreover, you can also prevent mold from growing in your bedroom by repairing any leaks in the air conditioning. I also recommend using a bed frame with slats that will air the mattress and ventilate the room regularly.
#4 The Attic
The attic and your insulation are prime areas for mold to grow. These hidden areas are warm and in the case of the attic are being heated all day by the rest of the home.
Spores could appear in the attic and insulation faster than anywhere else in the house.
This is why you’ll need to fix any leaks and clean the gutter periodically.
How to Clean Mold Patches: 6 Simple Steps
Mold spreads quickly. So if you’ve found a patch of mold in the home, you’ll need to clean it immediately. Make sure you get rid of it ASAP before it becomes a bigger problem!
If the patch of mold isn’t too big, you should be able to tackle it yourself without calling in a professional. But there is a method for cleaning mold that will help keep you and your family safe. Take a look at it below.
You will need:
- Protective eyewear
- A mask
- Put on the protective gear: gloves, eyewear, and mask.
- Ventilate the area. Keep the windows and doors open while you are cleaning.
- Conduct a test patch. Clean a small area that has been affected by mold. If your health is severely affected, call a professional to clean up the rest.
- Clean all surfaces with a disinfectant. Let the solution rest on the surface for 10 to 15 minutes before rinsing it away with hot water. For hard surfaces, you’ll need to clean the mold away with a stiff brush. But, for porous materials, please use a sponge.
- Dry the surface thoroughly. Keep an eye on porous surfaces. If mold resurfaces after a few days, discard the item or seek professional help.
- Keep the area ventilated after you have finished cleaning. This will ensure that the mold spores clear the atmosphere.
Mold grows quickly and spreads fast. It doesn’t take much for it to begin to appear in your bathroom, bedroom, kitchen, and other rooms in the house.
