Where does mold grow and how to identify mold damage in your house

It’s common to breathe and be in the presence of mold spores, as it’s part of the natural environment and has been present for thousands of years. Mold is responsible for maintaining and regulating ecosystems but, indoors, it should be prevented from growing. Most of the spores disseminated indoors are toxigenic and may result in health complications, especially for people struggling with respiratory conditions such as asthma, lung diseases, and allergies.


How and where does mold grow indoors? 


Mold is likely to grow in humid, damp environments. It only requires two elements for growth and dissemination: water and organic matter. As mold grows, it releases spores that travel through the air and into the most humid areas inside the property. The main concern when it comes to mold is that it feeds from the surface where it’s growing, which immediately puts at risk almost any object and area that may have been exposed to water or humidity.


The most common areas where mold grows indoors include:


  • Mold in the basement: It’s typically a moist area due to its lower level, especially if there are signs of water leaks, flooding, or condensation from HVAC systems. Some houses have laundry equipment in the basement, which makes for a dangerous place for mold to grow if not ventilated and kept as dry as possible.


  • Mold in the kitchen: Mold can grow inside kitchen cabinets and under the sink, especially if there is water damage and leaks on plumbing systems. Mold is particularly dangerous in the kitchen because it consumes wood, chipboard, and other organic materials, creating a more challenging situation to solve in terms of expenses and restoration matters.


  • Mold in the bathroom: Water vapor and damp carpets usually result in mold complications. It’s important to promptly fix water-related damage such as leaky pipes and excess moisture from poor ventilation.


  • Mold in the attic and crawl spaces: Fixing water leaks from roofs and walls is utterly important when it comes to preventing mold from growing in these areas. The attic and crawl spaces are tough places to look for mold and remediate it, so you’ll want to prevent it any way you can. If prevention fails, we recommend you turn to a professional to properly decontaminate these areas and provide you with insights on how to prevent mold from growing in the future.

How to identify mold growing indoors


How can you tell if there is mold in your basement, kitchen, bathroom, attic, or crawl spaces? Well, sometimes, mold damage is visible. Other times, however, we may come across what some specialists call “hidden mold”. 


Once they colonize a humid area, mold spores start to grow in the form of black dots, multi-colored rings, or yellowish stains. Mold has a very distinctive smell, it’s almost like smelling a wet pair of socks or clothing. Others perceive mold as an earthly smell, a very strong one. 


Now, hidden mold is a term used by remediation specialists and restoration companies to classify the mold hidden behind walls and other structures. Most people do not realize they’re dealing with a mold infestation until it has caused considerable, visible damage. To identify possible hidden mold damage, you have to look at the following signs of mold damage:


-Behind wallpaper, paneling, and drywall

-The opposite side of ceiling tiles

-Under carpets and rugs

-Wall surfaces behind furniture

-Air ducts

-Areas close to water pipes

Mold can have dangerous health effects


While it’s true that not everyone is affected by mold exposure in the way, mold produces allergens that affect people with respiratory health conditions. Depending on the type of mold that is growing indoors, it can cause skin sashes, red eyes, sore throat, and difficulty breathing. 


Continuous exposure to mold may result in more severe health complications. To remove it from your house or property, you need to fix the source of water damage. For tips on how to fix water-related damage in your house or property, read 12 Tips for Water Damage Repair, by The Family Handyman.
