How To Prevent Mould Damage: Essential Tips For Homeowners

Mould is a common issue in many Canadian homes, especially given the country’s diverse climate, which ranges from humid summers to cold, damp winters.

Left unchecked, mould can cause significant structural damage and pose serious health risks.

In this article, we’ll explore how to prevent mould damage with practical, actionable tips that will help keep your home safe and healthy.

Let’s get right into it!

Understanding Mould Growth

What is Mould?

Mould is a type of fungus that thrives in moist, warm environments. It reproduces by releasing tiny spores that can grow on almost any surface, including wood, drywall, and fabric.

When mould finds a suitable environment, it can spread rapidly, causing unsightly stains and potentially serious damage to your home.

Common Causes of Mould Growth

Mould growth is typically caused by excess moisture. This can result from various factors, such as:

Leaky pipes or roofs.
Condensation from high humidity levels.
Poor ventilation in areas like bathrooms and basements.
Flooding or water damage that isn’t properly addressed.

Why Canadian Homes Are Susceptible

Canada’s climate can contribute to mould problems in several ways. For example, coastal regions often experience high humidity, while areas with harsh winters may face condensation issues due to temperature differences between indoor and outdoor environments.

Moreover, many Canadian homes are built to be energy-efficient, which can sometimes lead to insufficient ventilation, creating ideal conditions for mould growth.

Importance of Moisture Control

Controlling moisture is crucial in preventing mould. Mould cannot grow without water, so reducing moisture levels in your home is the first line of defence.

Sources of Moisture

Common sources of moisture include:

Leaky plumbing: A small drip can lead to significant mould growth over time.
Condensation: Occurs when warm, moist air comes into contact with cold surfaces, like windows or walls.
High humidity: Ideal indoor humidity levels should be between 30% and 50% .

Tips to Control Moisture

Fix leaks immediately: Address any plumbing or roof leaks as soon as they are detected.
Use dehumidifiers: Particularly in basements or other damp areas. Dehumidifiers like the EcorPro 50-Pint Dehumidifier are highly recommended.
Ensure proper drainage: Make sure that water drains away from your home’s foundation to prevent seepage.

Proper Ventilation

Good ventilation is essential to prevent mould, as it helps reduce humidity and dry out any damp areas.

Areas to Focus On

Focus on high-risk areas such as:

Bathrooms: Install exhaust fans to remove steam and moisture.
Kitchens: Use range hoods when cooking to eliminate excess moisture.
Basements and attics: Ensure these areas are well-ventilated, as they are prone to dampness.

Ventilation Tips

Exhaust fans: Install them in bathrooms and kitchens to expel humid air.
Open windows: When weather permits, opening windows can help circulate air and reduce moisture buildup.
Install vents: Ensure that your attic and crawl spaces are properly vented.

Regular Home Maintenance

Regularly inspecting your home for signs of mould or potential moisture problems can prevent small issues from becoming significant problems.

What to Look For

Signs of mould include:

Musty odours: A damp, musty smell is often the first sign of mould.
Discolouration: Black, green, or white spots on walls, ceilings, or floors.
Peeling paint: This could indicate moisture behind the walls.

Preventive Maintenance Tips

Clean gutters: Regularly clean and maintain your gutters to prevent water overflow that could lead to leaks.
Repair cracks: Seal any cracks in your home’s foundation or walls to prevent moisture intrusion.
Check the roof: Inspect your roof for damage, particularly after storms, to ensure it’s watertight.

Immediate Actions if Mould is Detected

Act Quickly

If you discover mould, it’s essential to act quickly. The longer mould is left unchecked, the more damage it can cause.

Safe Removal

For small areas, you can remove mould using a solution of water and detergent. However, for larger infestations or if you suspect black mould (Stachybotrys chartarum), it’s best to hire a professional mould removal company.

Prevent Future Growth

Once the mould is removed, take steps to prevent it from returning:

Improve ventilation in affected areas.
Use moisture-resistant materials in areas prone to dampness, like bathrooms.
Install a dehumidifier to keep humidity levels in check.

When to Call a Professional

Recognizing Serious Issues

If you notice a large mould infestation, or if the mould keeps returning after cleaning, it’s time to call a professional. Mould remediation experts have the tools and knowledge to safely and effectively remove mould from your home.

Choosing a Professional

When selecting a professional, look for:

Certification: Ensure they are certified by a recognized body, such as the Institute of Inspection, Cleaning and Restoration Certification (IICRC).
Experience: Choose a company with a proven track record in mould remediation.
Reputation: Check online reviews and ask for references.

Costs and Considerations

While professional mould removal can be costly, it’s a worthwhile investment to protect your home and health. The cost can vary depending on the extent of the infestation, but it typically ranges from $500 to $6,000.

FAQs

What are the health risks of mould exposure?
- Exposure to mould can cause respiratory problems, allergic reactions, and exacerbate conditions like asthma. Prolonged exposure to toxic moulds like Stachybotrys chartarum can lead to more severe health issues .
How can I tell if I have a mould problem?
- Common signs include musty odours, visible discolouration on walls or ceilings, and persistent moisture problems. If in doubt, a professional inspection is advisable.
Are there any mould-resistant materials I can use in my home?
- Yes, materials such as mould-resistant drywall, insulation, and paints are available and can help reduce the risk of mould growth, especially in damp areas.
How often should I inspect my home for mould?
- It’s a good idea to inspect your home at least twice a year, ideally during spring and fall, when temperature and humidity changes can lead to mould growth.
Is it possible to completely prevent mould in humid climates?
- While it’s challenging to completely prevent mould in very humid climates, diligent moisture control and ventilation can significantly reduce the risk.
What should I do if I find mould in my home?
- For small areas, you can clean the mould with a mixture of detergent and water. For larger infestations, or if the mould returns after cleaning, contact a professional.
Can mould damage my home’s structure?
- Yes, mould can cause serious damage to wood, drywall, and other structural components, leading to costly repairs if not addressed promptly.
What is the best way to reduce humidity in my home?
- Use a dehumidifier, improve ventilation, and ensure that any water leaks are repaired quickly. Keeping indoor humidity levels between 30% and 50% is ideal.
Is it safe to stay in a house with mould?
- If the mould problem is minor and localized, it may be safe to stay while it’s being addressed. However, if there’s a significant infestation, especially of toxic moulds, it’s best to stay elsewhere until it’s removed.
How much does professional mould removal cost?
- The cost of professional mould removal varies but typically ranges from $500 to $6,000, depending on the severity and extent of the infestation .

Conclusion

Preventing mould damage is crucial for maintaining a healthy home, especially in a climate as varied as Canada’s. By controlling moisture, ensuring proper ventilation, and performing regular maintenance, you can significantly reduce the risk of mould in your home.
