Fogged Window
Tips for defogging your insulated windows
December 14, 2017

Have you noticed moisture or fogginess between the panes of your insulated windows? It’s a sign your windows are nearing the end of their life. Moisture that accumulates between window panes can cause permanent damage if left untreated.

To prolong the life of your window, you can defog your insulated windows yourself, but it’s not a miracle solution. Your windows will need replaced eventually.

Before you begin, make sure you don’t have tempered windows. You CANNOT drill into them to defog them and will have to hire a professional company like Lee and Cates to defog your windows.

Tempered glass is often found in conservatories or solariums where the window sills are low or have a white mark in the corner to identify them.

Step 1: Prepare and gather your tools

Block the area you’re working in from children, pets, and anyone else who may get in the way. Place the tools you need in this area: drill, broom and dustpan, and tape.

Step 2: Start drilling

Drill a small hole in the upper corner of the window that’s big enough to air out the window. Then, drill another small hole in the lower corner of the window diagonal from the first hole.

Step 3: Sweep and wait

Sweep away any glass fragments from the drilling and wait for the window to clear up. This can take anywhere from a few hours to a couple days.

Optional Step 4: Tape up the holes

Once the windows clear up, put tape over the holes and poke a hole in the tape with a needle. You can also opt to leave them uncovered. Both will help prevent the windows from fogging up again.

Remember, this is only a short-term solution and may not work if the windows are permanently damaged. At Lee and Cates, we can assess your windows and help you decide if professional defogging is possible or if your windows need replaced.
