Haven’t we all made works of art out of the condensation on windows?

Whether you drew hearts or smileys, being able to bring out your inner Picasso must’ve always felt like good news. But the condensation itself is actually bad news that you shouldn’t love or smile about. Here’s what that actually means: 

  • the humidity level in the room is high.
  • a sign of poor ventilation in the room.
  • can lead to mould growth if not addressed.

Living in Calgary, especially during the colder months, can bring with it some challenges when it comes to condensation on windows. The fluctuating temperatures and high humidity levels can lead to excess moisture building up on your windows, potentially causing damage to your window sills and frames. However, there are some seasonal tips you can follow to help reduce condensation and keep your Calgary windows in tip-top shape.

What Is Condensation and What Causes It?


Condensation occurs when water vapour in the air comes into contact with a surface that is cooler than the dew point temperature of the air. This causes the water vapour to condense into liquid water droplets.

Common causes of condensation include:

  • hot air meeting a cold surface
  • high humidity levels indoors
  • inadequate ventilation
  • structural issues in buildings

Condensation can lead to issues like:

  • mould growth
  • water damage
  • deterioration of surfaces


General Tips to Reduce Condensation on Calgary Windows


So, how do you protect windows in Calgary from the wrath of condensation? Discover our top tips below: 


Improve Air Circulation 


To improve air circulation, it’s recommended to keep your windows open for at least 10-15 minutes each day, regardless of the season. This allows fresh air to circulate throughout your home and helps to reduce any stale or stuffy air. 

However, during the warmer months, you may want to keep your windows open for longer periods of time to help cool down your home and increase ventilation. It’s essential to strike a balance between keeping your windows open and maintaining a comfortable temperature inside your home.

Additionally, keep furniture away from windows to allow air to flow freely. 


Use Exhaust Fans 


During activities that produce a lot of moisture, such as cooking, showering, or doing laundry, make sure to turn on exhaust fans. Vent this moist air outside to reduce the humidity levels in your home and keep the environment feeling fresh & cozy. 


Maintain Indoor Humidity Levels  


Ideally, the indoor humidity levels should be between 30-50%. If the levels in your home don’t meet this mark, use a dehumidifier. This is particularly important in areas like bathrooms, kitchens, and basements where moisture levels can be high.

With humidity being one of the main culprits behind condensation on windows, investing in a dehumidifier is a smart move.


Monitor Indoor Temperature  


You’ll want to be eagle-eyed when it comes to monitoring your indoor temperatures as well as this can drastically reduce condensation on windows. Try to maintain a consistent indoor temperature throughout the day to prevent drastic fluctuations that also contribute to condensation. Monitoring doesn’t have to be difficult though—simply use a programmable thermostat to regulate the temperature and keep it at a comfortable level.


Use Curtains and Blinds Wisely


What type of curtains or blinds are currently installed in your home? You might want to consider thermal curtains as they are a great way to insulate your windows and prevent heat loss, which can lead to condensation. These curtains are designed to trap warm air inside your home and block out cold drafts. 

Open curtains and blinds during the day to allow air to reach the window surface. Close them at night to add another layer of insulation. You’ll want to ensure they’re not pressed up against the glass which can trap moist air.


Weatherproof Your Windows 


Another way to prevent condensation on windows in Calgary is to ensure they are properly sealed. Make it a point to inspect them regularly for any gaps or cracks and apply weather stripping as needed to prevent warm air from escaping and cold air from entering your home.  Whether you’ve just recently opted for windows installation in Calgary or have had your windows for a while, this will help maintain a consistent temperature inside your home and reduce the likelihood of condensation forming on your windows.

You might also want to consider using insulating window film for an added barrier against the cold.


Air Dry Laundry Elsewhere  


Have you ever noticed condensation-rich windows on laundry days?

If this is the case, it’s best to avoid hanging wet laundry indoors, as it releases moisture into the air. But if you must air dry indoors, ensure it’s a well-ventilated area or near a dehumidifier. 


Check Your Vents 


Your vents are your strongest allies in the battle against condensation. As such, ensure that all vents from the dryer, bathrooms, and kitchen are clear and venting directly outside your home.


Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV)  


With proper ventilation being key to reducing condensation on windows, you’ll be in awe of the wonders that an HRV and ERV can do. 

A heat recovery ventilator (HRV) and an energy recovery ventilator (ERV) both work to improve indoor air quality while also increasing energy efficiency. These ventilation systems transfer heat and moisture between incoming and outgoing air streams, ensuring that the indoor environment remains comfortable and fresh. 

HRVs transfer heat between the outgoing stale air and incoming fresh air, while ERVs transfer both heat and moisture. By using these systems, your home can maintain a consistent temperature and humidity level without overworking heating or cooling systems—ultimately saving energy and reducing utility costs. That’s a win-win-win right there. 


Insulate Pipes 


Cold water pipes that aren’t insulated can contribute to your indoor humidity levels and cause condensation on windows. Simply insulating them will help prevent excess moisture from forming inside your home. 


Interior Storm Windows


If you have older, single-pane windows in Calgary, installing interior storm windows during the winter months can provide an additional barrier to moisture and cold.


Consider Window Replacement in Calgary 


If condensation is a persistent problem with your older windows—investing in double or triple-glazed windows with higher energy efficiency will be well worth it.
