How long does it take for mold to grow?

“It is not just your home and its contents that can suffer water damage caused by flooding, leaks, or high humidity, but mold growth as well—restoring property after water damage is more difficult because mold can grow quickly. Mold can grow in large numbers even if a small amount of moisture needs addressing correctly.”


How long does it take for mold to grow?


A water damage incident can result in mold growth because mold spores – tiny airborne particles that cannot be seen – are everywhere in nature. When mold invades your home, it can be hazardous to your health. In people with allergies or asthma, mold exposure can be especially dangerous.

Acting fast, however, can prevent mold growth in your home. To prevent mold from growing, you need to drop the moisture. When a flood or moisture problem occurs, how quickly does mold grow? Here, we will read all about how long does it take for mold to grow.


Mold growth after water damage

It is still possible for any amount of moisture accumulation indoors to lead to a mold growth problem, even if the water intrusion is limited and does not cause considerable damage. Mold spores exist everywhere, so mold can develop under the right conditions—organic “food” and moisture.

It only takes some moisture for mold to start growing in a house since it is full of porous organic materials like drywall, insulation, paint, and paper products. When water (or even high humidity) is present, it is just a few days before mold develops and starts damaging your home.

However, it is easy to prevent the problem—remove the moisture before mold has a chance to develop. What is mold’s growth rate? Can the spores take root in your home before you dry the premises?

In damp, fiber-rich materials, mold spreads immediately, causing wood, cloth, drywall, and other porous surfaces to become a breeding ground for mold. Often, a square inch of black mold can cover your home in a day.

Although this may not seem like much, a colony can quickly spread throughout your home and become out of control. When only two mold colonies occur in a specific area, the rate of mold covering entire square feet instantly decreases.

It’s usually too late when you notice black mold if it has already spread. The spores will appear in your home a month after they begin to develop since mold only appears once it starts colonizing. You can assess the damage as soon as you recognize the black mold. Keep in mind the following:

  • Mold color
  • Mold location
  • Areas with water damage
  • Noticeable odors (particularly a musty, dank smell)
  • A rough estimate of the amount of mold visible

When determining when to get professional help, you can use the square footage of mold as a general rule of thumb. It may still be possible to deal with mold damage if the spread is at most 25 square feet.

Once the mold spreads beyond 25 square feet, a contractor should be consulted to handle it properly.


How long after a flood does mold grow?

If the right conditions exist, mold typically grows within 24 to 48 hours after a flood. However, moisture, surface type, and temperature affect it. A darker, warmer, and more humid environment (70 degrees or more) leads to more rapid mold growth indoors.

The chances of mold spores spreading from one place to another also increase with time. Your home can quickly become infested with these microorganisms, resulting in more and more damage to your health as the hours pass.

Mold spores begin colonizing surfaces within 24 hours after flooding and become visible after 18 to 21 days. This happens, however, if the affected surfaces have yet to be dried and restored.

Consequently, it’s imperative to address water and moisture issues immediately after flooding. Cleanup and drying should occur as soon as possible to minimize the chances of mold growth.


What can you do to prevent mold from growing after water damage?

Accordingly, there is a 48-72-hour window between the beginning of mold growth and the water intrusion. During this period, mold is unlikely to develop if the flooded areas have completely dried off.

However, drying properly can take a lot of work. On its way to the lowest point in the house, water can get into various materials, including walls, floors, and ceilings.


Extract excess water

It will take time for these inaccessible areas to dry out after removing the excess water from the home. Open a door or window to allow air to flow outside, but these areas may need more time to dry out.

If moisture remains lingering, mold will develop quickly in any wall cavity, behind the baseboards, or under the carpet padding.


Dry out the area

Apart from this, most people concentrate on drying the affected room while neglecting nearby areas where water may have flowed hidden inside wall cavities or under carpets or tiles. Therefore, even if a person believes a property has dried out.

To successfully remove excess moisture in your home, you will need professional drying services within the 48-72 hour window when drying can prevent mold from forming.

With the expertise and specialized equipment required, the experts can safely remove standing water, locate hidden issues, and dry your home, preventing mold growth and further damage.


Common areas in your home where mold grows

Now that you know how long mold takes to grow, it’s time to examine the rooms most likely to be affected by it. This guide also offers some easy ways to prevent mold from growing in your home.


Common areas in your home where mold grows


The bathroom

Mold can grow in showers, bathtubs, sinks, walls and floors, and behind toilets. If the pipes under the bathroom sink leak slightly, mold may grow. Mold can also grow in cupboards under bathroom sinks.

Cleaning equipment under the sink may become moldy if it isn’t properly dried. Showers and bathtubs can also develop mold in the grout between tile and grouting. Mold can be avoided if you fix leaky faucets and pipes in your bathroom, dry surfaces after you wash them (like your floor after you mop), and install an extractor fan.


The Kitchen

There are many surfaces in the kitchen. Some near the sink are warm and wet. The kitchen also has hard surfaces and open areas, such as the floor and tiling. Mold can easily grow in some parts of the kitchen, while in others, it is more difficult.

Microwaves, refrigerators, and sinks are common places where mold grows in the kitchen. Since sinks are always damp, mold thrives in the places where wet sponges are left, and spores grow. In addition, drying racks often contain them under, around, and on them.

Also, foods that have passed their use-by date will likely start growing mold. If food remains in the fridge, the bacteria can spread quickly. The open air is another breeding ground for mold. A microwave or other warm, enclosed place is especially dangerous for food.

There’s nothing to worry about, though. Repair leaking faucets and pipes, dry countertops after cleaning, and remove old food from the refrigerator to prevent this from happening. Besides cleaning spills immediately, drying dishes, and installing an extractor hood, you can also help by immediately cleaning spills in the microwave.


The Bedroom

It is also possible for mold spores to grow due to condensation. Your windows become condensation-ridden when humid air meets a cold surface. To prevent condensation from forming on windows, it is advisable to wipe them down regularly.

You can also prevent mold from growing in your bedroom by repairing leaks in your air conditioning. Use a bed frame with slats to keep your mattress airtight and your room ventilated.


The Attic

Mold thrives in the attic and insulation. These hidden areas are warm, and in the case of the attic, the rest of the house heats them throughout the day. Therefore, keeping the gutters clean and fixing leaks is essential.


Is black mold dangerous?

Stachybotrys Chartarum is about as hazardous as other molds despite widespread perceptions that it’s highly toxic. According to the CDC, exposure to black mold does not cause serious respiratory problems, skin conditions, or other major health risks.

There are several ways in which black mold may irritate the body. There are several side effects associated with black mold exposure, including:

  • Having a cough
  • Asthma
  • Irritation of the eyes
  • Taking a sneeze
  • Migraines
  • Skin that itches
  • Irritation of the throat
  • Itchy
  • Having a fever
  • Breathing problems

The more severe the mold exposure, the more likely the symptoms will arise, but we can treat most (if not all) of the side effects.

A person with asthma, COPD, a compromised immune system, severe allergies, or other bodily sensitivity may experience more intense symptoms. However, black mold does not pose a life-threatening health risk.


Is it difficult to fall asleep when exposed to black mold at night?

Based on common misconceptions, the effects of prolonged exposure to black mold are not as severe as you may imagine. However, falling asleep may be more difficult when exposed to black mold at night.

The symptoms of a common cold—such as fever, sore throat, coughing, shortness of breath, and skin irritation—may wake you up, regardless of how well you fall asleep.

If black mold is present in your home, try to find another place to sleep. If you cannot escape the mold, stay as far away from it as possible. Seal off any affected areas where the mold has not spread or is not as severe. To the best of your ability, quarantine the mold until you can start treating it.

Mold exposure can have negative side effects, so consider wearing a face mask. If you choose this method, you may need a doctor’s recommendation for a sleep-safe mask; not all masks allow for safe breathing while sleeping.


How can you prepare while you wait for a mold remediation expert?

Hiring a mold remediation company may be necessary if you have not gained experience dealing with widespread mold. Whether you are unsure what to look for, how to handle the issue safely, or how to dispose of mold-contaminated items properly, we connect you with mold remediation companies with the best reputation, bonded, and insured. As such, you can limit mold exposure to yourself and other family members.

  • Seal off the area. Mold can spread to as much surface area as possible. Close the interior doors as much as possible in mold-affected areas and open them rarely. It is a good idea to keep the area under the doors blocked with foam insulation or plastic.
  • Use a fan. A fan circulates the air and disperses mold spores, but it can also dry any moisture in the area and prevent mold growth. Ensure you open the windows when you use a fan and that it blows outwards. Don’t let the mold return to your house!
  • Wear a mask. Wear a face covering whenever you are in a mold-infested area to prevent mold spores from entering your lungs. A surgical mask or respirator is ideal, but a dry T-shirt can make breathing easier.

Even though black mold can be hard to deal with in your home, you can fix it. Don’t wait. If you suspect black mold is spreading in your home, speak with your contractor immediately and note where and how it is spreading. Act now to restore your house’s homely feel.
