2 Tips For Reducing The Amount Of Condensation Inside Your Double-Pane Windows

Posted on: 24 January 2016

If you have noticed a lot of condensation building up inside the space between your double-pane windows, you may want to know how to get rid of it. Since this moisture is caused by a break in the window seals, you cannot completely get rid of it without replacing the windows. However, you can reduce the amount of buildup by using the two tips below.

Drill Small Holes In The Bottom And Top Of The Outside Pane

The main reason condensation builds up between your window panes is that the moisture is unable to escape because there are no openings in the glass. As the sun shines on the glass, the moisture inside heats up, making the buildup worse.

One way to remedy this is to drill a small hole at the top and bottom of the outside pane. This allows air to flow through the space between the glass, letting the water evaporate. Although not all of the moisture will do so, this can still help clear your view.

When drilling the holes, use a diamond-tip drill bit. The end of this bit is hard enough to penetrate the glass without cracking or shattering it. Also, place a piece of masking tape over the site where you intend to drill, as this will stabilize the glass and give it extra protection from breaking.

Plug The Holes With Dental Wax Before It Starts To Rain

While the above tip will help the moisture evaporate, it also leaves space for rainwater to enter the space between the window panes and accumulate. To keep this from happening, you will need to temporarily plug the holes before it starts to rain. 

For your temporary plugs, purchase a can of dental wax, found in the tooth care departments of pharmacies and department stores. To make each plug, roll a small amount between your fingers until it forms a ball that is slightly larger than the hole in your window. Then, carefully push the wax into the hole until it completely fills it. Repeat for each hole.

Once the rain stops and the sun comes out, remove the wax using your fingernail or the tip of a nail file. Unplugging the holes will need to be done after each rainfall to prevent the condensation from building up again.

Although you may be able to get rid of some of the condensation, you will never be able to see clearly out of your old windows. To be able to do this, you may want to speak to a contractor about having new replacement windows, such as Andersen windows, installed.
