Mold thrives in environments with excess moisture and specific temperature conditions, leading to various health issues.
​​Living in a property surrounded by lush greenery can be a breath of fresh air—literally. The beauty of nature can elevate your mood and provide a serene backdrop for your daily life. However, residing too close to the jungle can pose significant health risks, especially when it comes to mold growth in your home. Scientific research shows that mold thrives in environments with excess moisture and specific temperature conditions, leading to various health issues. It’s crucial for both renters and homeowners to understand the risks associated with mold and how to prevent it.

Molds, a type of fungus, play a vital role in breaking down organic matter in the environment. They can flourish in numerous locations, from soil and decaying plants to our homes. Mold reproduces by releasing spores, which can easily spread through the air, water, or even on pets.

How to prevent mold growth in your home
To keep your home mold-free, the key lies in managing moisture levels. Mold spores are ubiquitous, but they require moisture to grow. Here are common sources of moisture to monitor:
  • Roof leaks
  • Indoor plumbing leaks
  • Outdoor drainage issues
  • Damp basements and crawl spaces
  • Steam from bathrooms or kitchens
  • Condensation on cool surfaces
  • Humidifiers
  • Wet clothes drying indoors
  • Clothes dryer venting indoors
  • Poor ventilation in heating and cooking areas

Identifying a mold problem
Detecting mold is often straightforward; you can see or smell it. Mold typically appears as fuzzy, discolored, or slimy patches and often emits a musty odor. If you notice signs of mold growth, water stains, or warping, it’s essential to investigate further. Be sure to check areas prone to moisture, such as:
  • Bathrooms (especially shower stalls and tiles)
  • Window moldings
  • Refrigerator door seals
  • Air conditioning surfaces

Steps to eliminate mold
The first step in mold removal is addressing the moisture source. Identify and fix any leaks or damp areas. Discard porous materials with extensive mold growth, such as drywall and carpeting. Hard surfaces can be cleaned with soap and water. For larger infestations, consider hiring a licensed contractor. Always wear protective gear like rubber gloves and an N95 mask during cleanup. In areas where moisture cannot be eliminated, diluted bleach solutions can help control mold, but ensure proper ventilation to avoid irritation.

Should I have my home inspected?
In most cases, hiring a licensed mold assessment contractor is not necessary. Most people can identify and clean mold growth themselves. However, some may choose to hire a licensed mold assessor to help identify mold problems and their cause. They will often recommend a licensed mold remediation company to come in and clean the mold properly if needed. Check that a company is licensed by the Ministry of Natural Resources and Environmental Sustainability (NRES) through its Department of Environment (DOE). The Department of Occupational Safety and Health (DOSH), under the Ministry of Human Resources, also plays a role in regulating mold control and remediation, particularly in workplace settings. Additionally, the Ministry of Health (MOH) is involved in matters related to infection control and occupational health, which can indirectly affect mold remediation practices. If you are a co-op or condominium owner, you may need to coordinate such services through the building’s management company or owners’ association for your building.

What about renters?
As a tenant, it’s important to maintain cleanliness and monitor moisture levels in your home. If you discover mold or water damage, report it to your landlord immediately. If they fail to address the issue, consider contacting local health or building authorities to inspect your home.

Can mold affect your health?
Exposure to mold can lead to a range of health issues, particularly for individuals with existing respiratory conditions or weakened immune systems. Common symptoms of mold exposure include:
  • Level 1 symptoms: Watery eyes, sneezing, itchy skin, headaches.
  • Level 2 symptoms: Fatigue, chronic sinus infections, muscle pain.
  • Level 3 symptoms: Severe mental disorders, long-term memory loss, and vision issues.

​Understanding the risks associated with mold is essential for maintaining a healthy living environment. Whether you’re renting or owning, taking proactive steps can help safeguard your home and health.
