Hi, I have 4 year old casement windows that allow cold air in through the bottom. I am trying to remedy the situation and I am hoping for some advice. I am not sure if insulation is missing under the window sill or if I need to change the window stops. One other problem I have with them is a lot of moisture. When the temperatures really drop this creates an ice build up.
I have some V strip weather stripping between the window and the frame. It does help a little.
Thanks,
Pete
There could be any number of reasons as to why your windows are leaking air, but the most common culprit is worn out weatherstripping. Your next step should be to carefully examine the stripping currently installed in the window and see what kind of condition it's in. If it's notably crushed, deteriorated, or otherwise damaged, you need to consider replacing it.
If the weatherstripping is fine then the next thing you want to check is the orientation of the sash itself. Make sure the hinge and operators are working properly and that nothing is damaged or out of alignment.
As for moisture between the glass panes, there's not much we can do about that. You will need the panes replaced and resealed. A local glass shop should be able to assist you with that.
Hi Tom,
Thanks for your response. I will check the areas you suggested. The moisture is not between the glass panes, it is on the inside of the window. I can wipe it off, but when it really gets cold out ice forms inside the windowpane, too. My thought is there is not proper insulation under the window. I did run into this problem with our basement windows. I will have to look at that, unless you think it might be a different problem. Thanks again for your help.
Sincerely,
Pete
Gotcha, thanks for clarifying. In that case replacing the weatherstripping will probably fix that, but you may still be looking at a glass pane whose seal has deteriorated. See how things go after you replace the weatherstripping. In all likelihood that will fix all your problems, but keep a new pane in the back of your mind just in case.
Sounds good! Please let me know if you had any other questions and I will do my best to assist.
