How Long Does Mold Take To Grow After Water Damage

Does Mold Always Grow After A Leak

Mold Growth After Water Damage or Flooding | Rainbow International

No mold doesnt always grow after a leak. If the temperature isnt right or if the leak is properly dealt with quickly, theres a chance that mold spores wont be able to take root or grow. But this is the exception rather than the rule unexpected leaks, flooding, or even trapped humidity will generally lead to mold.

How Does Black Mold Damage Occur

As the mold grows on affected surfaces, it uses the material on the surface as its source of food. As it continues to consume organic materials, it causes more damage to the structure. The damage can become permanent and threaten the structural integrity of the affected areas if the black mold is left to continue eating the material.

When it comes to the health risks, people who are exposed to the mold can experience allergic reactions such as coughs, sneezes, skin and eye irritation, headaches, nasal congestion, and more. These health issues can become a bigger problem in the long run and develop into infections.

Control Levels Of Humidity

Mold thrives at high humidity levels, especially in places with a relative humidity of over 60%. If youre concerned that mold may develop, use a dehumidifier to lower humidity levels in the affected room.

You can also purchase a humidity gauge to monitor levels and help reduce the risk of mold growth.

Important Things To Keep In Mind If You Discover Mold

The last thing you want to do is spread mold around a building. Avoid using fans as they can push the mold spores into places without mold growth. This is doubly true for ventilation systems. If there is water damage, mildew or mold in ductwork or HVAC systems, using those systems will simply disperse spores around your entire home.

Anything thats suffered water damage should be taken outside. If any cloth or especially porous materials have suffered water damage they should likely be entirely discarded. This includes thigs like carpeting, water damaged sofas, etc.

Its important to first clean hard surfaces before you disinfect them. Solid wood, plastic, metal or glass surfaces can be cleaned with a stiff brush. Some people utilize commercial wet-dry shop vacuums to clean things like exposed wood studs and framing.

Once surfaces have been cleaned, they should be disinfected with a 10 percent bleach solution. Let the application sit for a minimum of 10 minutes before rinsing with clean water and letting it completely dry.

How Can I Prevent It

How to Tackle Mold after Water Damage?

Making sure that your home has a moisture level that is less than 50 percent of the air in your home is vital to preserving the ability to prevent mold from growing in your home. Consider installing a moisture meter in your home. This allows you to keep an eye on the moisture levels in your home and adjust your homes temperature as needed.

Opening your doors and windows and creating a cross breeze of fresh air can also assist in keeping moisture levels in your home down. The more the air can escape and new air enter, the less humid the air is in your home. Also, maintain the exhaust fans in your bathrooms so that excess moisture from a hot steamy shower is pulled up and out of your exhaust fans air vents. Keeping your fans on for up to 20 minutes after a hot shower allows all excess moisture time to be pulled up and out of your bathroom.

Lastly, check your home for any leaking pipes inside your walls. If you notice water pressure reductions in your home, it is a great idea to have the walls scoped for possible leaking pipes. This can be done by thermal imaging devices that identify the moisture levels.

How To Check For Mold After Water Damage

It can take as little as 12 days to see water damage and mold spores in your home. After youve taken the preventative steps, check certain places for mold growth. Organic surfaces such as wood should be checked most often as mold loves them.

However, there are many possible mild locations you may not know about or cant reach. For this reason, its best to hire water damage restoration experts to inspect and repair your home.

Observations From Mold Jobs

Being a mold remediator/educator, I have gathered similarly confusing, often conflicting input, from numerous jobs.

We observed that mold grew on some surfaces, but not others. We learned that the type of mold contamination found in homes is almost always what is called saprophytic mold. Saprophytic mold lives by decaying dead organic material, meaning the major ingredient we build with in North America wood and wood-related products like paper on drywall.

Additionally, research has shown that different types of saprophytic molds prefer different types of organic material , and different temperatures. They also prefer different amounts of wetness, usually called moisture content, but is correctly referred to as water activity.

So does mold really begin to germinate and grow in 24 to 48 hours?

In doing major mold remediations, the usual process is to work in conjunction with an industrial hygienist or other mold professionals, such as a certified industrial hygienist or indoor environmental professional .

Their job is to help identify what the contamination issues are, quantify the problem/issues and prepare a working plan, or protocol, for remediation.

In some situations, the IH will take samples from a suspect surface with a sterile swab. Sometimes the IH will collect air samples directly onto petri dishes containing an agar food source favorable to most molds.

How Cast Can Mold Spread

Mold doesnt take long to make its presence known. In fact, according to FEMA, mold growths or colonies can start to grow on a damp surface within as little as 24 to 48 hours. How is mold able to spread so quickly? Simple: because mold spreads through the use of sporestiny seeds that travel through the air in our home that are completely invisible to the naked eye. These spores latch on to another damp surface, and if the conditions are right, they quickly begin reproducing and spreading even further, oftentimes multiplying into millions of cells in as little as a few short hours. Before long, youre seeing spots growing on your walls that continue to get bigger and bigger.

How Long Will It Take For Mold To Appear After The Area Is Wet

This makes it more susceptible to water damage, and more likely to experience accelerated mold growth.

S To Take To Prevent Mold And Further Water Damage

When you are dealing with water damage and a potential mold problem, there are a few definitive dos and donts to implement as youre waiting for help to arrive.

  • Turn the water off in your home, especially if your water damage is coming from a source within your home.
  • Be sure to turn off all Air Conditioning units and heating systems. You should keep your home at a moderate temperature if possible, but avoid use of the central HVAC system. Excess coolness or heat can complicate the drying process.
  • Turn off any fans in the house, whether theyre ceiling fans, box fans, or free standing ones. Using your fans to dry out water can often spread any mold spores throughout the house.
  • Pick up any personal items from the floor that would add to your loss.
  • Try to either move furniture out of the wet area or lift it up and put something under the legs such as a block of wood that will keep it out of the water.

Leave everything the way it is and dont start throwing away ruined possessions until after someone has looked at the damage. Often professional cleaners can save possessions that otherwise might be unsalvageable. If possible, take photos to document all your damage. This will be helpful when you file an insurance claim.
