Many homeowners have concerns when they find condensation built up on the inside of their windows. The natural reaction is to assume that the window is somehow allowing the moisture or wetness to leak from the outside to the inside of the home. Typically, this is not the cause of the built up condensation.
Window Condensation Explained
Condensation is essentially moisture found in the air. It occurs when warmer moist air meets a cooler dry air. It's the same basic principal as taking a shower and having your mirror fog up. This is the same idea with your home windows, when warmer air meets the cool surface of the windows glass, it causes condensation to form. The condensation forms on your windows because the surface of window glass has the lowest temperature of anything found on your walls.
Condensation And Energy Efficient Home
The issue of condensation has become more prevalent with the advent of more energy-efficient homes and products. Today's homes are much more energy efficient and thus better at trapping the warmer heat inside the home. The result is a greater incidence of interior condensation on the window surface. Older and less energy-efficient windows let more heat escape from the house and therefore there was less moisture inside and less condensation.
Reducing Condensation In Your Home
So how do you reduce the amount of condensation in your home? The easy answer is to control the amount of humidity that exist within the home. If you notice condensation forming on the inside of your windows during the cold winter months, you can crack the window for several minutes and release some of the built-up moisture from inside the home.
When To Be Concerned
Condensation should only form on the inside of the inner pane or on the outside of the outer window pane. It should never be found between the two panes of glass. If you do find condensation between the glass panes, it is an indication that the airtight seal is broken and you will most likely need to replace one or both of the glass panes.
Window Condensation Q And A
Paradigm Windows And Condensation
Hello Dane, I’m not sure if you can help me with my question but thought I would reach out. I recently purchased a house (sold as “to be built”), moved in October and the builder used Paradigm windows. I live in Vermont and now that it is below 32 degrees there is an unbelievable amount of condensation where the windows meet and the bottom window, and when it gets below 20 degrees I have ice on the inside of the windows. It’s even more so if I have my curtains drawn.

Melissa, I'm going to send you to a link on our site that deals with condensation. In terms of answers, I wish I had something more concrete for you. Make sure that the next windows you buy have a high CR or condensation resistance, which can certainly help.

Amber, here is a link sent a condensation article that hopefully helps you out. The link is to the above explanation.
Dane, I recently had some series 80 windows installed at my stepmothers house. We have a 3-4” strip of condensation periodically showing up on the lower Exterior of one window.This is on a 8-0 3-0 window. The strange thing is there is a 7-0 3-0 just 10 ft. away in the same line and the same roof overhang facing the same direction.

Ken, I'd call up a local window company and ask for a bid for replacement windows. Then when he comes out, ask him to take a look. It doesn't cost you anything and while you're kind of duping the rep, who knows, you may have to get some windows down the line. He can probably tell you what the likely cause is.
Window Condensation Help
It is only October and I have moisture on the windows about an inch higb. Temp outside 55 temp inside 68! I have never heard of it happening like this unless the humidity is real high outside and the temp inside is real cold from running air! Also there are round knobs at each end of the window frame, not sure what they are for! My parents have regular Anderson windows that have a one piece flat sash that u can clean. These are two plastic pieces with drain holes that plug up and it takes forever to get dirt out of the split between the two groves ! Never saw a sash like this. Please help , just purchased house and can not afford to replace the new windows! I am wondering if they are installed correctly? Installer said moisture is normal!

Lorelei My advise would be to hire someone local to come out and take a look at the locking mechanism and the windows in general, especially given the time of year and the weather changes that will happen over the next month. I did a quick search for Jax Bldg Supply and a store in Michigan comes up. Is this where you are located? If so, call them and see if they know which window you purchased and whether they can help with your issue(s). They may work with installers who you might want to pay for an initial hour to come take a look and see if there is a low cost solution to your condensation problems.
