If window condensation is getting in the way, know you’ve got options. Foggy windows are caused by a number of factors including different temperatures on either side of the glass. While a hazy view isn’t ideal, it’s usually nothing serious. Here’s how to prep your windows for a home inspection and improved visibility.

Common Causes

Foggy windows may occur under a variety of conditions, though most pertain to temperature and humidity. If you’ve ever had a cold drink in summer, you’ve likely noticed condensation on the outside of your glass. That’s because the two different temperatures inside and outside cause humidity to form.

In a nutshell, the same concept applies to your windows. For example, warm weather and indoor air conditioning cause condensation on the outside of the window. In winter, you may notice condensation on the inside of your windows instead. Cooler morning temperatures sometimes have the same effect.

Another type of condensation may be due to indoor humidity. Wiping off the glass may solve the problem, but it doesn’t work for moisture in between windowpanes. While window condensation is rarely cause for concern, foggy double- or triple-pane windows are worth a closer look.

Practical Solutions

There are multiple types of window condensation and several easy fixes. Here’s how to address water build-up depending on the location.

Interior Condensation

Interior condensation or water on the inside of your windows is the most common type. Here’s how to solve foggy windows in your home’s interior.

Limit Your Humidifier

There are many reasons to use a humidifier in your home, though it may result in accidental window condensation. Instead, lower your humidity levels to remedy the problem. You could also limit your use to select rooms using smaller humidifiers or running them less frequently.

Reduce Moisture Levels

Another way to combat condensation is to proactively reduce humidity indoors. Consider using a dehumidifier as needed or investing in other similar products. For example, DampRid reduces ambient moisture without the use of electricity. Just remember to keep desiccants out of reach for your family’s safety.

Crank a Fan

Bathrooms and kitchens are especially prone to humidity, thanks to their frequent use of water. Counteract high humidity by running the exhaust or bathroom fan as often as needed. Running your fan for about 20 minutes after cooking or showering should do the trick.

Open the Window

Leaving your windows open might not be your first inclination, though it’s a good way to get the air flowing. Keep in mind you don’t have to leave them open for long—even a few minutes will suffice.

Start Circulating

Breaking up pockets of humidity in your home can help resolve condensation. If opening your windows isn’t in the cards, try running a ceiling fan instead for better circulation. Smaller fans get the job done in confined spaces and may be used as often as needed.

Adjust the Thermostat

While cooler outdoor temperatures lead to indoor condensation, upping the thermostat reduces the problem. Slightly warmer indoor temperatures help counteract the cool glass internally. To raise your window temperature without increasing the heat, use blinds, drapes or curtains for warmer (and clearer) windowpanes.

Use Weather Stripping

Weather stripping is often used to save energy and cut costs, though it also reduces window fog. The trick to this method is preventing warm air from escaping and mixing with the cold. 

Rethink Greenery

Keeping your plants close to the window is good for sunlight and bad for condensation. That’s because plants produce a certain amount of moisture that can be transferred to a nearby surface. Instead, place your plants slightly out of reach to keep condensation in check.

Try a Dehumidifier

If your home humidity is an issue, consider investing in a dehumidifier. These appliances draw moisture out of the air to lower the overall condensation. Some manufacturers offer humidifiers and dehumidifiers in the same unit, so check whether your humidifier includes both functions.

Add Storm Windows

If you haven’t already, consider the benefits of storm windows, particularly in cooler climates. These removable units are installed seasonally to save energy and limit condensation. If your storm windows form condensation while the permanent windows do not, it’s possible your permanent windows aren’t air-tight. 

Exterior Condensation

If you’re noticing water on the outside of your windows, know there’s no reason to worry. Here are a few ways to resolve your condensation problem.

Start Trimming

Does your home have shrubs or bushes outside the windows? If so, they could be a culprit. There’s no reason to do away with beautiful landscaping, though a little trim never hurt. Even an extra inch of space between windows and foliage provides better circulation. What’s more, trim edges let the sun in to warm up your windows from the outside.

Get Comfortable

Cooling off in summer is good for your mood and view. That’s because counteracting outdoor heat with more A/C lowers the average temperature of the glass. While outdoor condensation might evaporate eventually, this strategy helps speed the process along.

Internal Condensation

Most American homes feature single windowpanes, though double- and triple-panes are not unheard of. Here’s what you should know about condensation between the glass.

Easy Does It

When faced with a problem, it’s best to begin with the easiest fix. Start by cleaning the outer layers of your windows to rule out dirty surfaces. For example, outdoor debris or internal product buildup could just as easily cloud your window.

Replace the Panes

Condensation in between windowpanes is normally an indication of ineffective sealant. Replacing the panes could be worth your while if you’re interested in starting fresh.

Remove the Window

Depending on the condition of your window, you might consider replacing it entirely. Minor condensation might not bother you, but heavy fogging could be worth the fix. Keep in mind that individual panes aren’t always available for replacement.

Final Thoughts

Now that you’ve got the lowdown on condensation, it’s time to get moving. Test out which of these options works best for your home to keep your windows crystal clear.
