4 Signs There’s Mold in Your House

4 Signs There’s Mold in Your House

Mold in a home can indeed be a problem, especially for individuals with allergies, respiratory issues, or weakened immune systems. Mold spores are present everywhere and can enter homes through various means like open windows, doorways, and ventilation systems.

When mold finds suitable conditions like moisture and nutrients, it can grow on surfaces like paper products, wood, and fabrics. Mold growth is visible and often produces a musty odor, damaging household items and potentially impacting health.

Anyone who has had serious water damage in their home as a result of flooding knows the smell of mold. Mold and the spores it deploys are toxic.

There are hundreds of different species of mold. The two most well-known are Stachybotrys, generally referred to as toxic “black” mold, and Aspergillus, a common type of fungi — sixteen species of which are known to contain mycotoxins, which are highly toxic.

Worried you may have mold in your home, but not quite sure? Here are 4 red flags you should be looking for:

1. A recent water issue

Mold needs four things to grow — food (starch or sugar), a temperature between 41 and 104 degrees, oxygen, and moisture. It’s not uncommon to hear about mold in a home that had a leaky roof or a flooded basement. If you’re currently managing a water issue in your home or recently dealt with one, that liquid/moisture may have been the final ingredient that mold needed to start growing.

Water issues may be caused by:

  • Leaking pipes and roofs
  • Condensation build-up
  • Poor ventilation
  • Landscaping issues
  • Flooding
  • Air conditioning systems

2. Visible dampness or damage

You may not think you had a recent water issue, but look for signs of water damage anyway. The red flags can include warped surfaces, peeling paint, or stains/discoloration on the walls, floor, or ceiling in your basement, attic, or other rooms in your home.

Tell-tale signs can include:

  • Visible Mold Spores
  • Warped Walls
  • Dark Tile Grout
  • Squishy Floor
  • Uneven Attic Insulation

3. That smell

Remember that mold may not be visible. It could be behind a wall or above ceiling panels. And, while it may be hard to describe, most of us know that musty mold smell.

Mold typically emits a musty, damp, or earthy smell. Severe infestations may produce pungent odors resembling rotten meat or sweaty socks.

If you can smell something musty from your HVAC system after turning it on and you noticed dark spots on its filter, it might be contaminated by mold.

4. Allergy symptoms

Mold exposure can worsen asthma symptoms, leading to respiratory infections, shortness of breath, severe coughing, and sneezing. In extreme cases, mold growth in the lungs can cause additional symptoms like chest pain and fever.

Certain types of mold can be more dangerous than others due to their ability to produce mycotoxins, which are harmful to humans. Here are some of the more hazardous types:

  • Chaetomium: This mold is toxigenic and often found in wet, dark environments like drywall, wallpaper, baseboards, and carpets. Exposure to Chaetomium can cause neurological damage and certain autoimmune diseases.
  • Aspergillus: Common in U.S. homes, Aspergillus can cause lung infections, respiratory inflammation, asthma attacks, and allergic reactions. It poses a risk to individuals with compromised immune systems.
  • Penicillium: Found in water-damaged areas, Penicillium can lead to asthmatic symptoms, bronchitis, and other respiratory problems when trapped inside homes.
  • Fusarium: This mold thrives in cold temperatures and can cause eye problems, nail infections, and worsened conditions for individuals with weakened immune systems.
  • Alternaria: A common allergy-causing mold present in many climate zones during spring and summer. While not typically found in building materials, it can be airborne indoors and cause health issues.

If you have any these signs of mold there are two important questions you need to be able to answer:

  • Where is the mold growing?
  • What is the water problem which caused or is causing it?

Mold inspection

Prior to testing, have a thorough mold inspection done of your home. If mold is discovered, you can usually forgo mold testing and proceed directly to the removal stage. If no mold is found and you still think you have a mold problem, or if mold was found and you believe there may be more, it’s time to test.

Mold testing

When it comes to testing for mold, professionals use specialized methods such as culture tests, air quality tests, surface tests, and bulk tests to accurately identify the type of mold present and its extent. These professionals are trained to handle mold safely and can provide comprehensive solutions for removal and prevention. To ensure consistency and prioritize safety when dealing with mold, it is advisable to refrain from touching mold yourself and instead opt for professional assistance.

Mold testing can be crucial in identifying and addressing mold issues effectively. Hiring a professional mold inspector is recommended as they have the expertise and equipment to conduct thorough assessments without risking exposure to harmful spores.

The bottom line

Remember, mold can pose serious health risks, especially to vulnerable individuals like the young and elderly. By engaging a qualified mold inspector, you not only ensure a more accurate assessment but also reduce the potential health hazards associated with handling mold improperly.

Prioritizing caution and seeking professional help can lead to a more effective and safer resolution of mold issues in your home.
