Cleaning Condensation on Window

How to Stop Condensation on Your Windows Overnight

Window condensations can be a true annoyance that could even damage your windows. Condensation can rot away wooden moulding and destroy plaster.

Excess moisture can lead to other problems as well.

Condensation on windows happens when there is an excess level of moisture in the building, and most frequently happens in the winter, when warmth within the home’s atmosphere condenses onto the colder windows.

Exterior condensation of windows is just the result of dew and happens when the window is a colder temperature than the dew point.

Condensation between panes happens when either the inter-pane seal is broken or when the window’s internal desiccant reaches a saturation point.


How to Stop Condensation on Windows (Inside)

Fortunately, there are many ways you can stop condensation from forming. As interior condensation is the most common form of the problem, we shall cover its solutions first.

1. If you use a humidifier, use it on a lower setting

If you notice condensation in your nursery (if you have one), chances are high that the humidifier is at fault. If your home has any sort of humidifier, you should consider lowering its setting. Less moisture in the air means a lower chance of condensation.

3. Get a moisture absorber

Moisture absorbers such as the UniBond Aero 360 are products that help absorb moisture from the air and condense it into a bucket. These are great for bathrooms, the kitchen and closets (which also helps protect your clothes) because they help mitigate excess moisture in the area.

4. Use extractor fans in the bathroom and kitchen

Use your extractor fans whenever you cook or shower. Both activities known to produce a lot of moisture. By keeping your fan on during these activities, you help remove extra moisture from the area.

Try to keep the fan running anywhere from 15 to 20 minutes after you finish cooking or showering.

5. Circulate the air

Keep your ceiling fans rotating in a clockwise fashion, even in winter, so that you push warm air downward toward the floor.

6. Open the windows

As long as it is not too chilly, consider leaving your windows open. This will help give some of your home’s warm, moist air an easy escape route.

7. Increase the window temperature

There are two ways to go about this:

  1. Raise the temperature of your home
  2. Use blinds, curtains and drapes to better trap warm air against the glass

8. Install weatherstripping

Weatherstrip is a kind of foam that seals windows and doors. Weatherstripping keeps more warm air inside of the home and is useful in diminishing condensation if you resort to storm windows during winter. Furthermore, weatherstripping is also a handy feature to have because it boosts your home’s energy efficiency.

9. Use storm windows

If your home has older windows, storm windows are a great way of limiting the formation of condensation against your interior windows. The area between two windows means that the inner window can remain warmer.

Storm windows also help your home’s energy efficiency by lowering your winter heating bills. You may run into storm windows that evidently have condensation but their ability to reduce interior condensation means that there is less of a chance of building up frost.

Storm window condensation is a sign that your inner windows have a leak and may warrant both a closer examination and reapplication of weather stripping.

10. Move plants

Plants generate moisture as part of their respiratory process. If you happen to have a sizable number of plants standing near your windows, consider relocating them elsewhere so that you wind up with a drier environment around your windows.

11. Invest in a dehumidifier

A dehumidifier is a potentially costly but simple way of drying out a home. If a full size unit is too costly for your budget, you might want to look into acquiring a miniature version.

It is important to remember that not all models are configured the same; some need to be manually activated while others activate once the humidity level of the area reaches a certain saturation point.

12. Get an air-to-air exchanger

An “A2A exchanger” has the same cost and difficulty settings as a dehumidifier. What this device does is pull in fresh air from outside of the home while simultaneously expelling air from within the home.

While it makes sense that this sort of device would be great for expelling excess moisture from the home, it also carries the benefit of sending any pollutants along with that moisture.

13. Invest in some window insulation kits

Window insulation kits can be placed on the interior or exterior facet of a window and their main purpose depends on which side of the window you install them.

Placing them on your interior windows is the best way to deal with interior condensation. While you can install them along the exterior of windows, their only real contribution will be a diminishing of your energy costs to cool or heat the home.

Notably, sealing an interior window when you have condensation between it and a storm window will also help with condensation.


How to Stop Condensation on Windows (Outside)

There are far less issues when working with this situation. Here are a few tips:

1. Apply a coating of hydrophobic chemicals to the window

This will cause the water to slide off in a manner similar to how a duck handles moisture.

2. Just wait

External condensation naturally evaporates if given enough time.


How to Stop Condensation Between the Panes

Your options when dealing with this particular condensation boil down to three choices:

1. Clean your windows

This should always be your first choice when it comes to dealing with any haziness. While you might be dealing with condensation, the haze may actually originate from some sort of buildup, such as from window cleaner or even grease from activity in the kitchen.

2. Swap out your window panes

Now if it turns out that you do indeed have condensation between your window panes, you will need to swap out the glass. Success in this task depends upon several factors, such as the design, age and manufacturer of your original window.

3. Replace the entire window

In the event that replacing just the glass proves to be unfeasible, you will need to replace the entirety of the window.

Considering how many innovations have been made over the decades, having your windows replaced is generally a good idea if your windows are considerably aged.

By changing out your windows, the chances are good that your newer windows will be much more energy efficient and less prone to developing condensation.
