How Quickly Can Mold Grow

Ventilation Issues And Moisture Buildup

How Fast Does Mold Grow?

If your home has poor ventilation, you may have an increase in humidity and a need to get rid of mold in your ducts. A free flow of air is needed to properly circulate vapors, and stifling that flow can lead to condensation building up on the windowsills, basement windows, or other areas where the colder internal air clashes with the heat from the exterior. Many times, an HVAC unit will extract a certain amount of water from the air, but if the unit is older and doesnt route the water to a free-flowing drain, there is a greater likelihood of leaks or overflowing drip pans. The presence of moisture creates an opportunity for mold.

Black Mold Smells Like Must And Mildew

Small areas of molds are often concealed behind wallboard and never really breakthrough to the visible side. But the clumping molds often have a very distinct aroma when growing.

Small areas of molds are often concealed behind wallboard and never really breakthrough to the visible side. But the clumping molds often have a very distinct aroma when growing.

The smell of black mold is quite distinctive, commingling mildew with a must. The odor is usually most noticeable after it comes into contact with a surge of air, such as when pushed through a homes ducts. Or after people have not been around the rooms indoor air for some time, such as in Joe and Cathys case.

Mold Growth Conditions Indoors

The reasons behind why mold has decided that a home is the perfect environment to start its development can stem from a multitude of factors. Mold is said to thrive in warm, dark environments where there is moisture present and a surface that the mold can have as a food source. Generally, moisture is an instrumental cause of mold growth since the other conditions that are needed in a home are typically already present in the home beforehand.

Humidity within the indoor environment will also play a role in mold growth as the levels increase it will promote the growth of these funguses. Moisture intrusions in the home will also add to the increase in humidity levels, particularly if ventilation is poor within the environment.

How Does Mold Spread

Mold is a difficult contaminant to remove from a home, especially due to its rapid ability to spread throughout the whole environment both on the surfaces and in the air. The element of mold that gives this fungus the ability to spread thoroughly throughout the environment is mold spores, a reproductive spore that is produced from mold in an effort to grow the mold in the environment. Mold spores easily travel in the air and are not detected by the human eye, due to its minuscule size.

As mold spores travel in the air, they will eventually settle onto surfaces in the environment, evoking the growth of the mold on the surface. This will ultimately lead to the spreading of the mold in the confined space of a home.

Can You Dry The Water Damage Yourself

While you might think that you can dry out your water damaged areas yourself by using fans and wet-dry vacuums, weve found that most homeowners never fully dry out the water damaged areas. This is simply because they dont have the proper tools to detect hidden pockets of mold-growing wet areas.

Your best bet is to hire a professional like Jenkins Restoration to dry out your water damaged areas. These companies have specialized equipment that dries out wet areas and they both prevent and deal with mold regularly.

The cost to professionally dry your water damaged areas is almost always covered by insurance so it doesnt cost you anything more to have a restoration company like Jenkins Restorations dry out your water damaged areas to speed up the time to getting life back to normal.

How Long Does It Take For Mold To Become Visible

Mold Growth After Water Damage

Although mold begins to grow within a day or two of taking root after a water or excessive moisture issue, it takes a bit longer for the mold colony to become big enough to be seen with the naked eye. If left unchecked, mold will become clearly visible within about two to four weeks. Other factorssuch as high humidity, warm temperatures, lack of airflow, or contaminated watercan also speed up this process, making it easier to identify sooner.

What To Do To Keep Mold From Generating After Water Damage

There is a 48-72 hour window between the water intrusion and the beginning of mold growth. Indeed, it is considerably hard to extract excess water and dry the areas entirely as water can get into all kinds of materials in many parts of your home.

So here’s what you need to do hire a water damage restoration company to get your home back in order.

The Spread Of Mold Growth

How fast does mold form on wet drywall?

Summer is the perfect temperature for mold growth, but the breezes and winds that come through are also ideal for carrying mold spores around the house. Mold will thrive on soggy carpet or cardboard, inside ductwork, on insulation, or the wooden support structures of your home. It grows and multiplies quickly, putting your health and home in danger if left unaddressed. Wherever you have dark places in your home, you need to be more vigilant in checking for the presence of mold. You may end up smelling the musty odor before you see visible signs of growth, but you can be on the lookout for signs of a water leak or water damage.

How Fast Does Mold Spread

Mold spreads in as little as a few hours. When a mold spore lands on a moist organic material, it roots into the porous surface and begins to feed off the organic substance. Within hours, the harmful microorganisms start spreading to adjacent moist areas, damaging the structural integrity of the material theyre attached to. Once mold gets a foothold on a surface in your home, it quickly fills the air with thousands of spores that spread throughout the building, affecting more and more areas with every passing hour.

So, the only way to prevent mold from infesting your home following an incident with water damage is to dry the premises within the first 48 hours after the water intrusion.

How Does Mold Form

Mold and mildew are made up of resilient organisms that thrive, not just survive, pretty much anywhere. As long as they have a steady supply of food, oxygen, and moisture, they can multiply quickly and easily take over entire homes and buildings.

Mold feeds off of organic materials like wood, drywall, and fabric. When moisture builds up in areas of the home made with these materials, fungus moves in. With the right conditions, it can quickly get comfortable and start making a home for itself in your house. Even a certain level of humidity can be enough to create the required conditions for growth.

If your water damage is limited, theres still a risk that there could be mold lurking behind the walls and inside the dark corners you cant see. The best way to keep a small problem from growing out of control is by acting quickly.

How Fast Does Black Mold Spread

Mold begins spreading the second a spore hits damp, fiber-rich materials wood, cloth, drywall and other porous surfaces are fair game in the spreading of mold. In many cases, black mold can spread to cover an entire square inch of your home per day. This may not sound like much, but the spread can quickly spiral out of control as more colonies develop in your home. Even with just two specific areas of mold colonies, the rate for mold to start covering entire square feet is immediately cut in half.

Unfortunately, black mold is typically already a widespread problem by the time youre able to catch it. Since mold isnt usually visible until it starts colonizing, you may not even realize its growing in your home until almost a month after the spores have begun to develop. Once you do recognize the presence of black mold, you can start assessing the damage right away. Be sure to take note of things like:

  • The color of the mold
  • Where the mold is located
  • The presence of water damage in the area
  • Any noticeable smells
  • The approximate square footage of mold visible

As a general rule of thumb, you can use the square footage of mold to decide when to get professional help. If there is less than 25 square feet of mold visible, there may still be time to handle the damage yourself once the spread surpasses the 25-foot mark, its best to get in touch with your local contractor to handle the mold professionally.

The Science Of Mold Growth

How Fast Can Mold Grow?

With this conflicting information, it is time for more research.

Working in conjunction with my fellow instructors, we did a detailed scientific/technical literature review and found a peer reviewed paper entitled Controlled Study of Mold Growth and Cleaning Procedure on Treated and Untreated Wet Gypsum Wallboard in an Indoor Environment, by Michael Krause, CIH, with Veritox Inc.

Krause and his associates performed basically the same test that we did, except they did it with a number of untreated and treated wallboard sheets under very controlled scientific conditions.

According to Krause, it took at least a week to confirm that invisible microscopic growth structures had formed on wet untreated wallboard in a closed office.

Mold growth colonies were not visible on untreated drywall until three weeks into their eight week experiment.

The first mold types seen were Acremonium, Penicillium and Cladosporium. Stachybotrys was never seen. Visible mold did not grow on wallboard that was coated with a primer.

Additionally, a study done by Dr. Michael Berry, prepared for the Carpet and Rug Institute , showed that drywall and framing lumber, when exposed to a controlled environment with a temperature of 80 degrees Fahrenheit and a relative humidity of 80 percent, did not display visible mold until week five .

A listing of a few of these papers is at the end of this article.

How To Get Rid Of Mold

As already understood, mold is not pleasant and it is preferable to get rid of them sooner than later. There are many easy and quick ways to remove the mold at an immediate level. Some of the most obvious ways are:-

1. Remove Excess Water

Excess water will make the whole surrounding quite moist and would encourage the growth of mold.

2. Dry out the area

In extension to the first method, the area has to be absolutely dried after the excess water has been removed. This would not allow mold to find desirable conditions to germinate and hence, the damage, if not totally eliminated, can, at least be controlled to a certain extent.

In a way, this is the maximum we can do on our own. And we do need some secondary and more expert help to control the growth of mold.

Dealing With Mold After Water Damage

Mold and damp staining painted wall surface around an internal home window.

Mold doesnt need a significant amount of water damage to grow any amount of excess moisture in a particular area is enough to harbor the right conditions for mold growth as long as it has an organic food source and moisture, the fungus can grow anywhere.

Provided that it is a property structure, home and buildings provide plenty of organic food sources on which mold can grow. This includes any porous materials, such as paint, carpeting, drywall, paper products, etc. So the only ingredient needed for mold to grow is the moisture, such as in cases of high humidity or excess water. Give it a couple days and you will have a huge problem.

On the other hand, there are a number of ways in which mold can be prevented: just eliminate the moisture source before the fungus has time to develop. But how much time do you have before it starts to grow? How soon does the area need to be dried before the spores make a nest on your structure?

How Long Does It Take For Mold To Grow In Wet Drywall

Mold spores are present everywhere in the environment, they start developing as soon as the right conditions are made available for its growth and multiplication. Drywall being extremely porous, is pretty sensitive to water-induced damage. Even a small exposure to water can result in severe stains on the wall.

So, Does wet drywall always mold? Well, Once drywall comes in contact with water, there is only a tiny timeframe available to salvage it before the mold or mildew begins to set in the wall. Some mold spores can germinate after just 12 hours of drywall being in wet conditions.

How to prevent mold?

The only way to prevent mold infestation in drywall following a water damage incident is to dry it within 48 hours after water intrusion. The 48-72 hour window is critical to prevent mold growth as it usually takes 24 to 48 hours for mold to germinate and grow. Once fungus gets a hold on a drywall surface, it can be the breeding ground for thousands of spores and quickly spread in the air around the wall with every passing hour.

Moisture trapped in drywall can deteriorate and make the drywall bulge out, crack, or breakdown. You can buy more time and curb the water exposure by using bleach or mold/mildew detergent, which can slow down the mold development of the drywall.
