Key Reasons Mold Speedily Spreads in Homes
Excessive moisture can spread fast if left unchecked. The reason it is so apt to spread quickly is that it reproduces through tiny airborne spores. These can float easily through the air and settle on damp surfaces. Once they land in a moist, warm environment mixed with organic material (like wood, drywall, or fabric), they begin to grow and multiply rapidly.
With the many dangers of mold in your house and for you personally, it’s vital to stop it from spreading and eliminate what is already present. You may be able to get help from your home insurance policy. You may be wondering how to fix mold problems, but first, you need to know the signs of it in your home. Here are 14 signs you have a mold problem brewing in your home.
#1 Musty Odor in the Air
You may notice a damp, musty odor in the air, which can be a sign of excess moisture or poor ventilation in your home. Basements are especially prone to these smells, so be sure to check there first.
#2 Discolored Patches on Walls
Discolored patches on the wall can be a sign of mold growth. Usually, the color of the patches is green, black, brown, or even white. These patches may also feel damp to the touch, indicating moisture and growth behind or within the wall.
#3 Water Stains on Ceilings
Look up to see how your ceilings appear. Since roofs can become damaged during heavy storms and wind, there is a chance that small amounts of water can creep in, causing mold to form on the ceilings. If you see water stains on the ceilings, it’s time to take a closer look. You may be surprised to know that your home insurance can save you during natural disasters.
#4 Warped or Bubbling Paint
Have you noticed the paint or wallpaper on your walls beginning to bubble or look distorted? If so, there is a chance that you have one of the signs of mold on the walls. This can quickly lead to warped-looking walls. There may be a small leak or area where moisture can get into the house.
#5 Black Spots in the Shower
Ever notice black grime around a shower door or around the faucets? The shower is a prime place for mold to accumulate due to the moisture in the bathroom.
#6 Peeling Wallpaper
When wallpaper starts peeling back, it is normally because it is damp. Any sign of moisture or dampness means mold can grow there.
#7 Respiratory Issues or Allergies
As noted above, mold in the home can cause issues with allergies, among other things. If you or anyone in the house is experiencing increased respiratory problems or allergies, take a closer look at your home’s interior for excess moisture.
#8 Persistent Dampness in the Basement
Basements are prone to getting damp if they are not properly sealed. Any tiny fracture or crack in the foundation can lead to water and moisture getting into the basement.
#9 Rust on Pipes
Do your pipes look rusty anywhere in the house? If so, they are likely getting wet from some type of leak, allowing mold to fester.
#10 Condensation on Windows
Check your windows for a film of condensation on them. Your window sill may be torn or damaged, thus allowing rain to seep in.
#11 Discolored Grout
If you notice the coloring of your tile grout has changed, then something is amiss. There could be mold growing and spreading.
#12 Growth on Furniture
Furniture can also retain moisture, especially since it’s made of organic materials like wood or fabric, making it more susceptible to dampness and musty odors. If you see growth on your furniture and wonder, “What type of mold is this?” that forms on furniture, it is potentially a fungus.
#13 Soft Spots in Flooring
When wood becomes wet, it starts to soften and deteriorate. If you notice soft spots in the floor, take a closer look at the wood underneath for dampness and moisture.
#14 Excessive Humidity Levels
Too much humidity is a sure way to invite moisture and, consequently, mold growth. Some ways to prevent humidity include regularly opening your home’s windows, using exhaust fans, and using dehumidifiers.
