Understanding Why Mold Is Becoming More Common Indoors
Alberta’s weather has always been unpredictable—cold winters, humid summers, and wide temperature swings that can happen overnight. While these extremes are nothing new, the way we build and insulate our homes has changed dramatically in recent years. Tighter, energy-efficient construction helps conserve heat, but it can also trap moisture indoors. When combined with Alberta’s variable climate, this creates the perfect conditions for mold to grow.
Mold spores are everywhere, but they only become a problem when they find moisture and a suitable surface to grow on. In modern homes, this can happen inside walls, around windows, beneath flooring, or near areas where condensation builds up. Common causes include roof leaks, poor ventilation in bathrooms or basements, and even over-humidified indoor air during winter.
Health Canada notes that prolonged exposure to indoor mold can cause or worsen respiratory symptoms such as coughing, wheezing, and nasal congestion. People with asthma, allergies, or weakened immune systems are particularly sensitive. The good news is that with professional mold testing and proper moisture control, homeowners can identify and address issues before they escalate.
When and Why to Schedule a Professional Mold Test
Mold isn’t always visible, and by the time you notice spots on walls or ceilings, the problem may already be widespread. Testing helps determine the type, source, and severity of contamination, guiding the next steps for safe removal.
There are several warning signs that suggest it’s time for a professional mold assessment. If you notice a persistent musty odour, visible staining, or recurring allergy-like symptoms that worsen indoors, mold could be present. Condensation on windows, water stains on drywall, or peeling paint are also indicators of excess moisture that can encourage mold growth.
Another common situation that calls for testing is after water damage. Even a small flood, plumbing leak, or roof issue can lead to hidden mold growth within days. Testing helps verify whether mold is present in areas that aren’t visible—such as behind drywall or under flooring—so you can take corrective action early.
Professional mold testing provides accurate, unbiased information about what’s in your air and on your surfaces. It goes beyond visual inspection, offering measurable data to confirm whether mold levels are within safe limits or if remediation is required.

How Mold Testing and Removal Protect Your Home and Health
A professional mold test with Ask Environmental involves both air sampling and surface sampling to capture the full picture of your indoor environment. Air samples measure the concentration of mold spores, while surface samples help identify the species growing on specific materials. These samples are then sent to a certified laboratory for detailed analysis.
Once results are available, you’ll receive a clear explanation of what they mean. This includes identifying the types of mold present, their relative concentrations, and whether they pose a health concern. The findings guide the next steps in remediation—determining the scope of work, setting up containment areas, and establishing safe removal methods.
If mold is detected, certified technicians follow a structured remediation process that includes isolating affected areas, using HEPA-filtered air scrubbers, and removing contaminated materials safely. Proper containment prevents spores from spreading to other parts of your home. After removal, air quality testing confirms that spore levels have returned to normal before the space is restored.
Beyond remediation, the key to preventing future mold problems lies in addressing moisture sources. That means improving ventilation, fixing leaks promptly, and managing indoor humidity. Regular maintenance and periodic air quality checks help keep your home safe and your family healthy.
Alberta’s changing climate makes it more important than ever to stay proactive. Heavy rainfall, melting snow, and humidity spikes can all increase the risk of moisture intrusion, especially in basements and crawl spaces. With mold testing, you gain the knowledge and confidence to protect your home from long-term damage.
