Why You Should Never Ignore Mould in Your Home

Mould in the home is often underestimated by homeowners; however, it presents both immediate and long-term dangers to your health and property. In Ontario, where seasonal humidity is high and weather can fluctuate dramatically, conditions for mould growth are common. Unfortunately, it is common for mould to [significantly] spread before most homeowners recognize the issue — sometimes behind walls or beneath flooring. At Preferred Restoration Contractors, our certified mould removal professionals have seen how quickly a minor issue can escalate into a major health and safety hazard.
Mould is typically the result of moisture that has been left untreated for a period of time. Causes for this may include: a slow plumbing leak, roofs that drip during rainstorms, or high humidity in areas like basements and crawl spaces. In many cases, it begins with subtle signs—a musty odor, occasional coughing or sneezing indoors, or a small discoloration on walls or ceilings. Homeowners often try to wipe it away with household cleaners, only to find it repeatedly returns. This is because mould often roots itself deep in porous materials such as drywall, wood, or insulation.
The health risks associated with mould should never be ignored. Prolonged exposure has been linked to respiratory problems, allergic reactions, asthma attacks, and skin irritation. For individuals with weakened immune systems, mould can be particularly dangerous. Children and elderly family members are also more susceptible to the side effects of living in a mould-infested environment. Unfortunately, because mould releases microscopic spores into the air, it can spread from room to room without being seen.
Attempting to remove mould on your own can often make the situation worse. Scrubbing mould without containment can release more spores into the air and potentially contaminate unaffected areas. Furthermore, most DIY products only remove what’s visible on the surface. They fail to eliminate the source of the moisture or fully eradicate the colonies growing in hidden spaces. That’s why it’s essential to bring in trained professionals who understand how to assess, contain, and remediate the problem safely and thoroughly.
At Preferred Restoration Contractors, our mould remediation process begins with a complete inspection of your home. We use specialized equipment to detect hidden moisture and mould, then create a detailed remediation plan. Our team of IICRC-certified technicians follows industry-standard safety protocols, using negative air machines, HEPA filters, and physical barriers to prevent cross-contamination. We treat affected areas using professional-grade products that not only remove the mould, but also help prevent its return.
In addition to cleaning and removal of mould, we also focus on fixing the source of the problem. Whether it’s a leak in the foundation, a malfunctioning sump pump, or inadequate ventilation in your bathroom, we provide long-term solutions that keep moisture levels under control. We believe comprehensive mould prevention comes from addressing the environment as a whole.
Ignoring mould doesn’t make it go away—it only gives it more time to grow and cause damage.
