How to avoid condensation on windows?

Anti-fog for glass and home windows

When there is suddenly too much humidity in the house, it is normal for condensation and fog to form on windows and glass. Although this fogging on the windows is not a problem, it is nevertheless annoying, especially during the winter, when it is cold.

Over time, I’ve found some really effective anti-fog tips and tricks. Here is how to avoid condensation on the windows of the house.

1. Condensation and fogging on windows in the morning

If every morning when you get out of bed, you notice condensation and water at the bottom of the windows of the house, you must quickly solve this humidity problem.

The reason for this fogging in the morning is simple, the relative humidity in the house is much too high. This condensation on windows and glass is often visible during the cold season and particularly when the nights are very cold in winter.

How to avoid this humidity on the windows?

If you do not have a central air exchanger in the house (mandatory now for new constructions) it is always possible to purchase a dehumidifier to reduce the humidity and thus avoid this fog in the morning on the Windows.

Of course it’s not as efficient as a real air exchanger system (which controls the humidity level in a house) but it will be beneficial to solve your problem of fogging and condensation in the windows.

2. Condensation on windows in the fall and winter

Condensation on home windows is most common in the fall and winter when the cold weather returns.

Indeed, in winter when the temperature fluctuates a lot during the day and night, condensation can quickly form on the windows.

Pay particular attention to the temperature of the rooms in the house!

So to avoid fogging on the windows, you can raise the temperature of the coldest rooms in the house by an additional 1 or 2 degrees. This will prevent the windows from fogging up, especially at night when the outside temperature drops below 0 degrees.

Remove screens from windows in winter!

To avoid having too much fog and condensation on the windows, I recommend that you remove the mosquito nets in winter. There will be much less condensation at the bottom of the windows thanks to this trick.

3. A shorter shower to avoid fogging

The bathroom is the place in the house where condensation on the windows and fog on the mirror is the most abundant. It’s completely normal, you might say, but be careful, because too high a humidity level in the bathroom can cause mold on the walls and ceilings.

The longer you stay in the shower, the more condensation and fogging will occur on the bathroom mirror and window. Same thing if you put very hot water in the bathtub, condensation will be present in the room and throughout the house. If you don’t have a fan to evacuate the humidity in the bathroom, you can leave the door and the window ajar to avoid this condensation.

You can also run a portable dehumidifier when you take a shower to prevent humidity and fogging in the bathroom.

4. Avoid having too many green plants in the house

condensation on windows and green plants

Do you have a lot of plants in the house? Do you often notice the presence of fog on the windows that are close to green plants? Well, be aware that plants can be one of the causes of this condensation on the windows.

What should I do with my plants to avoid condensation?

Indeed, plants maintain the humidity of the house and can therefore be good triggers of condensation in the windows and glass of the house. Avoid placing plants too close to windows especially during the night where condensation most often forms due to the base outside temperature.

5. Use a moisture absorber for windows

If you don’t want to buy a dehumidifier (too expensive or too noisy) to remove condensation on the windows of your house, then a humidity absorber can be a good choice.

Operating without electricity, there are models of humidity absorbers that can help against condensation and fogging on the windows. It is also a very effective gadget against humidity, against bad odors and even to prevent stains from mold and humidity.

You can therefore place a moisture absorber near problematic windows and glass!

6. Open curtains against window condensation

keep the curtains open to avoid condensation and fogging

When the nights become cooler in winter it is important not to block the window panes in the house, because the fog may be there every winter morning. Curtains and other window coverings are no exception to this rule, they prevent air from circulating freely, thus causing condensation.

Free your windows to avoid condensation!

When the heating is on in the fall and winter, you should therefore keep the curtains open so that the heating system also brings some warmth to your windows. It is this heat, among other things, that prevents condensation on the windows of the house.

As I said earlier in the article, I also suggest that you remove the screens from the windows. You are going to see a big difference in the amount of fog in the morning.

7. Control humidity to prevent fogging

The high level of humidity in the house can of course be the main cause of condensation on windows and as well as fogging of glass and mirrors. So how do you know the humidity level in a house? A hygrometer is the gadget to buy.

By purchasing a hygrometer you will be able to know the percentage of humidity that there is in the house. If the humidity is too high, window condensation may occur quickly. It will be easier to control the humidity level and especially to avoid fog on the windows of the house during the night.

Why not buy a hygrometer online to control the ambient humidity of the house? 10 Tips offers you this very popular model and above all at an excellent price:

This device is essential to know and control the humidity level in a house.

8. Avoid storing firewood indoors

Do not store firewood in the house due to humidity

Firewood stored in the basement contributes to increased humidity and therefore condensation on windows in the house.

If you have windows in the basement, you will quickly see fog forming there during the night because of the firewood which is still damp. The problem is that this humidity will not only stay in the basement, it will spread throughout the house.

So avoid storing your firewood in the house as much as possible. Better is a shelter near the house or directly in the garage or the shed. If not, run a dehumidifier in the basement to thoroughly dry firewood and to remove fog from windows.

9. Leave the doors open

To avoid too much condensation and mist in the bathroom, in the laundry room and in the kitchen, do not close the doors.

A hot shower, a hot bath, a pot of boiling water or 1 wash cycle and condensation forms on the windows and panes of the house.

By leaving the doors to all rooms in your home open there is a more efficient natural air exchange. Same thing in the basement, do not hesitate to open the doors to remove humidity and condensation.

10. Anti-fog tip for house windows

If you want test a really effective anti-fog thingboth for the windows of the house and the windows of the car so here’s how to do it:

  1. Take a clean, soft cloth and pour in a few drops of dish soap.
  2. Scrub the panes and windows in circular motions.
  3. Dry the surface with a clean, dry cloth to finish.
  4. Repeat weekly to prevent fogging of windows.

Of course, if you have a real moisture problem, you will have to solve this problem first, because the condensation will always be present on the windows.

11. Condensation on windows? Check the dryer!

As I have already mentioned in this article, the laundry room gives off a lot of humidity and therefore condensation. But it’s not necessarily because of the washing machine, but rather because of the dryer.

Indeed the dryer produces a lot of heat and therefore more condensation on the window of the laundry room. It is therefore important to check that it is well attached to the air duct to avoid this condensation.
