Managing condensation and indoor humidity is a significant challenge for owners of older homes in Alberta. Whether you live in Edmonton, St. Albert, or rural areas of Sturgeon County, proper moisture control helps maintain your home’s value and comfort—an essential consideration for homeowners, landlords, and anyone working with a local Realtor when buying or selling older properties.
Understanding Condensation in Older Homes
Condensation occurs when warm, moist air contacts cooler surfaces, such as windows, walls, or basement floors. In a northern climate like Alberta’s, where temperatures drop well below freezing, these surfaces can remain cold for months, contributing to persistent dampness and even mould growth. For prospective buyers viewing older listings, your REALTOR® will likely suggest having a home inspection to identify potential problem zones.
Common Sources of Indoor Humidity
- Cooking and showering without proper ventilation
- Basement seepage or inadequate foundation drainage
- Blocked or malfunctioning air vents and fans
- Overuse of humidifiers during winter
- Drying laundry indoors without sufficient airflow
Steps to Reduce Condensation and Moisture
There are practical steps homeowners can take to reduce condensation, improve indoor air quality, and preserve the structure of their older property. These are also key points for real estate professionals when advising clients.
- Improve ventilation: Use kitchen and bathroom exhaust fans and consider energy-efficient heat recovery ventilators (HRVs), which are recommended in many Canadian climate zones.
- Seal air leaks: Caulking around windows, doors, and attic hatches will help prevent cold air infiltration and reduce the temperature differential that leads to condensation.
- Insulate properly: Upgrading insulation in attics and walls not only improves efficiency but also maintains warmer surface temperatures indoors.
- Check foundation drainage: Ensure grading slopes away from the house, with downspouts extending at least two metres from the foundation.
- Monitor humidity: Use a hygrometer to keep indoor humidity between 30% and 50%, as advised by Natural Resources Canada.
The Realtor’s Perspective on Moisture Concerns
When listing an older property in Edmonton or St. Albert, a CREA-affiliated real estate professional will often emphasize the value of energy retrofits, proper insulation, and moisture management. These improvements can attract eco-conscious buyers and reassure investors that the home is structurally sound. Likewise, for buyers evaluating vintage properties, your REALTOR® may recommend consulting a home inspector or contractor familiar with Alberta Building Code standards.
