Condensation On Your Windows: What Does This Mean and What Should You Do?

 

Having condensation on your windows can be a concerning scene, and it should be addressed if it is happening to your windows. You want to ensure your windows are functioning properly and doing their job. 

But did you know that there are different types of condensation, and it makes a difference where it’s appearing on your windows? Every house is different, and every homeowner has a different issue.

That being said, here are some common questions we get asked about condensation on your windows that might help you, followed by tips to help reduce excess humidity and condensation in your household.

 

“Every morning, I see moisture collecting on the outside of my windows, but I just did a window renovation! Why is this happening?”

Explanation: If you’re seeing condensation on the outside of your windows, consider the weather and time of day. If it’s been cold at night and you’re seeing the condensation in the morning, it’s similar to when you have condensation on your car early in the morning. The inside temperature of your house is simply warmer than the outside temperature, and that causes moisture to collect. This happens even on newer high performance windows, so unless you’re seeing moisture between the panes or inside your home, this isn’t a big cause for concern.

The fix: Wait for the sunshine to come out! This should dry the condensation up. However, if you are seeing the condensation all day and your windows are aluminum or wood, it’s time to replace your windows with energy efficient, vinyl windows.

 

“My window tracks are black with mold, but I only see condensation inside, not between the panes. My windows are just dirty, right?”

Explanation: One of the biggest problems we see with condensation is when the house is too humid indoors. This not only causes condensation on the inside of the windows, but can cause mold on windows or walls, a musty smell, or stains on the ceiling. This is extremely unhealthy for your family, and doesn’t look very good either!

The fix: Replace your ventilation system. That moisture needs a way to escape! If your bathroom fan doesn’t hold up a few squares of tissue paper on its own, it’s time to consider a new one. When paired with a de-humidistat, your bathroom fan can control humidity levels in your home around the clock. This is the number one way to reduce humidity and condensation inside the home.

“I’m seeing condensation in between the panes of my windows. I clean and clean, but nothing takes it away!”

Explanation: If you’re seeing condensation between the two panes of glass in your windows, your window seals have broken. This means that air is flowing freely from outside to inside, and your house is not energy efficient. Some homeowners will replace just the glass, but this is a “band-aid fix”. When the outside temperature fluctuates, the glass in your windows will expand and contract. If your window seals or frames are metal, they won’t move with the glass, causing the seal to break. This lets in moisture, and that’s when you see the condensation.

The fix: Stop the problem at its source! It’s time to replace your windows with energy efficient vinyl windows. If it’s not in the budget, Centra may have a promotion that fits your needs or consider breaking up your window upgrades into more affordable phases.

 

Tips To Reduce Excess Humidity And Condensation:

  • Crack open a window or door for a few minutes daily to have air flow through your home
  • Open your drapes and blinds to allow air to circulate against the windows
  • Use energy efficient bath fans with a de-humidistat to regulate the moisture in the air
  • Use exhaust fans in your kitchen, laundry, and bathrooms
  • Make sure your clothes dryer is properly vented to the outside and your vent ducts are sealed
  • Open the louvers in your attic, basement, and crawl space and ensure they are the correct size to allow proper ventilation for the space
  • Open fireplace dampers to provide an escape route for moisture

Turn down your heat to reduce the difference in temperature between inside and outside

These tips should help address the condensation in your home. If it persists, contact us to have an Energy Efficiency and Window Expert assess your windows.

 

To recap, if you are experiencing condensation on your windows, it will be in one of these three places.

Outside the home:

Condensation outside the home shows that your windows are working. Your new windows are stopping heat from escaping, so the outside surface is now cold. This only occurs a few times a year and will disappear as the day gets warmer.

Inside the home:

Condensation on the inside can be typically seen on bathroom or bedroom windows and is a sign of too much relative humidity in the home and that proper ventilation is needed.

A 100 CFM bath fan hooked up to a de-humidistat will turn the fan on when needed and solve the problem of condensation.

Between the glass panes:

If you are seeing condensation between the panes of glass, the window system has failed. This is a service or warranty issue that you will need to address. Give Centra a call and we would be happy to bring out an estimator for replacement on windows.
