Does mold on my house pose health risks?

Yes, mold and algae growing on your house siding can pose health risks, particularly for people with allergies, asthma or respiratory sensitivities. Mold spores can be carried by wind and enter your home through windows, doors and the ventilation system. Possible symptoms include: eye irritation, nasal congestion, sneezing, coughing and sore throat. Additionally, the bacterium Gloeocapsa Magma that causes black streaks on roofs can also contribute to degraded air quality. Regular professional washing eliminates these contaminants at the source and protects your family's health. On Montreal's North Shore, where humidity is high, we recommend annual washing to maintain a healthy environment.
