Have you noticed mold or mildew growing in your property? While a small patch may seem harmless, it often indicates an underlying moisture problem. The reasons for mold growth are prolonged freezing Toronto winters and water intrusion due to heavy rainfall or leaks. This constant humidity and condensation create moisture and invite mold growth. Mold in a small area can be treated with DIY methods and mild chemical cleaners. If it is spread over a large area, then it is advised to call professional help. It may also be hidden behind the drywall, beneath the carpet or flooring and in attics. It can easily develop in 24 to 48 hours.
Mold and mildew indicate a moisture problem. Grey or green patches on your ceiling and a musty smell may indicate mildew growth in your home. If you notice these warning signs, scheduling a professional mold inspection can help identify the source even before the problem worsens. ONT Restoration offers mold removal Toronto services to remediate and remove mold.
Why Toronto Homes Are More Vulnerable to Mold
Toronto properties experience conditions that are an ideal environment for mold growth, such as freezing winters, water intrusion, seasonal snowmelt, heavy rainfall, basement moisture, roof leaks, aging plumbing systems, and poor ventilation, which can introduce excess moisture into a home. Poor ventilation also favours mold growth in moist areas.
Let’s see the key differences between common mold and black mold found in Toronto homes.
Black Mold vs. Common Mold in Toronto Homes
Common household mold is often easier to spot in its early stages and is typically found on visible surfaces. Black mold, however, is more likely to develop in hidden areas behind drywall or insulation, where it can spread unnoticed and potentially cause more extensive property damage before being discovered.
