The Impact of Humidity

Posted on by msi-admin

Humidity plays a crucial role in the health of your home and can significantly impact the likelihood of water damage and mold growth. Understanding how humidity levels affect your environment is essential for homeowners looking to maintain a safe and healthy living space. In this blog, we’ll explore the relationship between humidity, water damage, and mold, and provide tips for managing humidity levels in your home.

What is Humidity?

Humidity refers to the amount of moisture in the air. It’s typically expressed as a percentage, with higher percentages indicating more moisture. Relative humidity levels above 60% can create an environment conducive to mold growth and other moisture-related issues.

How Humidity Contributes to Water Damage

  1. Condensation: When warm, humid air comes into contact with cool surfaces, such as windows or pipes, condensation occurs. This moisture can accumulate and lead to water damage, especially if not addressed promptly.
  2. Increased Water Table: High humidity can be indicative of a rising water table, which can lead to groundwater seepage. This can cause water to enter basements and crawl spaces, resulting in significant damage.
  3. Material Saturation: Prolonged high humidity can cause building materials—like wood, drywall, and insulation—to absorb moisture, weakening them and making them more susceptible to damage.

The Link Between Humidity and Mold Growth

Mold thrives in moist environments, and high humidity levels can create the perfect conditions for mold spores to grow. Here’s how:

  • Optimal Growth Conditions: Mold spores need moisture to germinate and grow. When humidity levels exceed 60%, they can quickly multiply, leading to infestations within 24 to 48 hours.
  • Hidden Mold: High humidity can lead to mold growth in hidden areas, such as behind walls or under carpets, making it difficult to detect until significant damage has occurred.
  • Health Risks: Mold can pose health risks, including respiratory issues, allergies, and other health problems. Managing humidity is crucial for protecting your home and your family’s health.

Tips for Managing Humidity in Your Home

  1. Use Dehumidifiers: Investing in a commercial grade dehumidifier can control humidity even in the harshest conditions preventing the chance of mold. Units should be sized correctly and able to handle the work load, as most plastic made brands can not.
  2. Improve Ventilation: Ensure proper ventilation in your home, particularly in areas like kitchens and bathrooms. Use exhaust fans to reduce moisture buildup during cooking and showering.
  3. Seal Leaks: Regularly inspect your home for leaks or gaps in windows, doors, and roofs. Seal these areas to prevent moisture intrusion.
  4. Monitor Indoor Humidity: Use a hygrometer to monitor humidity levels in your home. Aim to keep indoor humidity between 30% and 50% for optimal comfort and mold prevention.
  5. Address Water Damage Promptly: If you experience water damage, address it immediately. Quick extraction and drying can prevent mold growth and further damage.

Managing humidity is a vital part of maintaining a healthy home environment. By understanding its impact on water damage and mold growth, homeowners can take proactive steps to protect their properties. Elevated levels of humidity can lead to rapid mold growth and structural damage to your property.

Identifying Mold on Carpeting

Posted on by msi-admin

Just because mold is not immediately apparent or visible on a carpet’s surface does not mean that mold growth is not in progress. In fact, mold will probably only be visible on the surface of carpets in unusually severe cases of growth, such as carpet damaged in flooding that has remained wet for some time. The following are some examples of identifiable instances where mold growth has occurred or is likely to occur:

  • Visible Mold Growth: As stated above, this can be a rare case, but sometimes it may be obvious from visual inspection that mold growth is occurring. Carpet in this condition is most likely not salvageable and should be disposed of and replaced. Often, even if mold growth is not visible on the top of carpeting, it may be occurring underneath the carpet where it can’t be easily seen. Carpet suspected of containing mold should always be examined on both sides.
  • Carpet Mildew: Any discoloration or odor on carpeting that might be described as mildew is probably a case of mold.
  • Wet or Water-Damaged Carpet: Any carpet that has been subjected to water damage from flooding or standing water will most likely need to be disposed of. Conditions are ripe for mold growth, in this case. Even if visibly apparent mold growth has not yet begun, it is highly likely to happen unless the carpet is completely removed, cleaned and dried within 24 to 48 hours. Even then, removal and cleaning are not guaranteed to prevent mold growth. It is more likely that the carpet will need to be replaced.
  • Wet Padding Beneath Carpet: If padding beneath the carpet has become wet for any reason, or has become moist from condensation, the padding as well as the carpet on top are at risk for mold growth. The padding may need to be replaced, as will the carpet, in some cases.
  • Basement Carpet: Carpeting in basements below grade level is especially at risk in areas where humidity is high, or where wide temperature swings can produce condensation.
  • Odors and Stains: There is a wide range of things that can cause odors and stains on carpets. If mold is suspected, samples can be taken and sent for analysis to determine if mold growth has occurred.

What is Acremonium?

With wet conditions, Acremonium grows quite well.. When Acremonium is found indoors, it usually originates either from outdoor air or from contaminated crawl spaces or from contaminated building materials that recently experienced wet conditions like flooding. However, the spores of this fungus are formed in a slimy mass resulting in limited aerosolisation: therefore its prevalence may be low in air samples.

It grows indoors on building materials such as drywall, acoustic and thermal fiberglass insulation and in some cases insulated ducting. Crawl spaces, wet bathrooms with a lack of proper ventilation or exhausting and continuous wet basements are ideal for Acremonium. 

Acremonium has often been associated with contamination by Stachybotrys chartarum, which is often referred to as “Black Mold,” as both fungi is favor very wet circumstances. Allergenic reactions to Acremonium includes hay fever, asthma, hypersensitivity and pneumonitis. Potential opportunist or pathogen effects are known to cause hyalohyphomycosis, keratitis, mycetoma, and onychomycosis. Also known to cause infections in immunodeficient patients and causes infections in persons with wound injuries.

When mold is found in your home, trust the professionals at Mold Solutions & Inspections to properly handle the removal the first time under the guidance of the IICRC protocols.
