Understanding Mold and Its Impact on Your Property


Mold is more than just an eyesore—it can threaten your property and your health. In Ontario, frequent humidity and occasional flooding increase the risk of mold developing in homes and businesses. Mold spores are invisible and can spread quickly, attaching themselves to:

  • Walls and ceilings
  • Carpets and upholstery
  • HVAC systems
  • Personal belongings

The dangers of unchecked mold go beyond surface damage. Mold exposure can cause:

  • Allergic reactions and skin irritation
  • Worsened asthma or breathing issues
  • Persistent headaches or fatigue
  • Damage to wood, drywall, and building materials

If you see or smell mold, prompt, professional intervention is crucial. Mold removal in Ontario isn’t just about surface cleaning; it requires addressing the moisture problem at its source. DIY methods often fall short, allowing mold to return or spread further. Trusting certified professionals like PuroClean ensures that every step, from identification to complete remediation, is handled correctly, so your property remains safe and healthy.
