Hiding In Plain Sight: Mould Presents Significant Health Risks

What You Can’t See Can Still Make You Sick

A congested chest. A lingering tickle in the throat. It’s easy to assume the cause is COVID-19 or a seasonal virus. But many of these symptoms - especially in the fall - may actually be triggered by something far more common and far less publicized: mould.


“As the weather cools and people spend more time indoors, we start hearing about increased irritation from indoor air,” says Kevin Sullivan, President of Paul Davis Restoration of Northern Virginia. “Very often, mould growth is the hidden culprit - especially in areas like crawlspaces, basements, bathrooms, laundry rooms, and attics.”


How Mould Affects Your Health

Mould exposure can lead to:

  • Eye and throat irritation
  • Wheezing or shortness of breath
  • Headaches and fatigue
  • Difficulty concentrating

While a healthy individual may experience mild or no symptoms, those who are elderly, immunocompromised, or living with asthma or allergies may suffer serious health impacts even at low exposure levels.


What About Black Mould?

Most people have heard alarming reports about black mould, but Sullivan says colour doesn’t tell the full story. “Don’t waste time trying to identify mould by appearance. Green, black, or brown - it all needs professional attention,” he explains.


Why You Need a Professional

If mould is present in your home, don’t try to clean or assess it yourself. Certified remediation technicians will:

  • Inspect walls, carpets, attics, and hard-to-reach spaces
  • Identify the source of moisture
  • Apply proven, health-safe products to treat mould
  • Prevent future growth by correcting the root issue


Not All Mould Is Bad, but the Risk Is Real

There are over 200,000 species of mould, and the vast majority aren’t dangerous. In fact, mould plays a vital role in our ecosystem, producing everything from yeast to mushrooms. But when certain species grow unchecked in damp indoor areas, they pose real health risks.


Concerned About Mould in Your Home?

If you suspect mould might be affecting your air quality or your health, don’t wait. Call the experts at Paul Davis Restoration for a full inspection and remediation plan.
