How do you remove condensation between two windows?
By Cindy from Lorain, OH
The IG (insulated glass) units need to be replaced. The seal has been lost.
Your best bet is to call local glass companies and ask for free estimates. It can be a DIY project for some people, but unless you have the correct tools and such, it is something that most glass companies can do within a reasonable amount of time. Labor should be inline with the cost of the IG unit depending on your area.
(I used to be a window and door sales rep and grew up in the window and door industry. Despite some of the claims from previous posts that have been archived, an entire new window is not in order 85% of the time, just the IG unit, new stops/glazing material and patience.)
You can't IF you have double glazed windows. They are sealed. What you have is a leak in the seal. The window has to be replaced. Is that what you have?
Cheap method (never tried it, but might work):
1) Drill a small hole in the glass in an inconspicuous location, preferably a corner. You'll need a glass/tile drill bit due to the hardness of glass.
I had condensation built up in my old glass doors. I read somewhere about drilling a small hole and allowing the condensation to evaporate then filling the hole with silicone. It sounded logical to me. And since I'm very familiar with tools I decided to give it a try. I went to Home Depot and picked up a drill bit specifically for glass. Not cheap but I figured it was cheaper than hiring a pro to do the job.
Then I set to work drilling a tiny hole. I hadn't drilled but a few seconds and OMG did I find out fast that this was the wrong thing to do! The entire door shattered! Teeny tiny pieces top to bottom, side to side.
I covered it with plastic wrap and tape and called a professional. I wound up doing what I should have done to begin with. I replaced the door! So please, People, don't try drilling a hole to allow condensation to dry out. Call a pro! He may or may not be able to dry it out, but either way it takes a pro to fix this problem!

To drill out a hole in the glass is not going to stop the problem of condensation. I would strongly suggest using a humidifier in the home or leaving a window open to release some of the moisture in the air. Besides you cannot drill anything that's tempered. Tempered is a ceramic glass heat baked for strength.
The reason you can not slice one side of the glass is that the sealant is holding both pieces of glass so tightly that you will more than likely break and shatter the glass. This is dangerous. In addition, if you try to silicone or glue another piece of glass back on to the other side of the glass it will be messy and look awful.
It is far better to call a glass repair company. They will give you an estimate and make up a brand new sealed double pane unit and switch out your old glass.
My company is based in Colorado Springs. We do this type of work every day and have 25 years of experience.
I'm not a window salesman or expert but I'm a contractor (that focuses on energy efficiency and low waste) and I frequently get salvaged double pane windows. My first experience with the moisture issue was when another contractor buddy of mine suggested we clean some salvaged windows at a self serve car wash. They all had moisture between the panes by the end of it. These were all used on an indoor installation of an office wall and within 2 weeks all the moisture was gone and were spotless.
You can open the window, and from the side of the window frame, use a long drill bit and drill into the caulking that holds IGU together. Make a hole at the top and bottom to allow for air circulation to clean out the condensation. Use a blow dryer to blow air into the small bottom hole to speed up the window clearing.

How do you get rid of moisture between window panes?
It sounds like you have an insulated glass unit in your window. You can tell by looking to see if there is a metal spacer bar between the two panes. If you do have an insulated glass unit, it will need to be replaced...not the entire window. The reason you see moisture between the panes of glass is because the seal has failed.
Depending on the age of the window, it might be worthwhile to make a phone call to check to see if the insulated glass is still under warranty. Those units are sometimes warranted for many years.
We replace lots of glass each year due to fogging between the panes - the moisture you're seeing is because the seal failed.

I have condensation between my window panes. Do I need to find a company to come and get it out?
