My mother had storm windows installed several years ago. She is having a problem with condensation and mildew on the inside of window & storm window. What is causing this? Weep holes are not clogged. Thanks for any help. Also I forgot in my original post that she has condensation on the windows on the inside of the house.

 

check the weather striping around the storm windows, if worn out replace, and check the caulking, if you have voids, recaulk.

Storm windows will not stop condensation %100 and you will most likely get some, more so because it's made out of aluminum.

 

hi
She will always have condensation for there are not air tite.
It' might have been cheeper to get insert windows to replace the old ones.
she would have save on heating cost and ac.
Like they say you get for what you pay for. Sorry

Storm windows are REALLY old tech. Almost guaranteed to have condensation problems. Air leakage from both sides. Like pgtek suggests, replace the windows with retrofits, and the problem WILL be solved.

 

Dear Softsoc;

One important factor in controlling condensation is air circulation. Sometimes placing a fan in the room that has the worst condensation problem will help a lot. Consider how well your bathroom fan works at clearing the damp after you shower. Perhaps there is a problem with your mothers furnace fan or duct system, have a pro check it out.

The second factor is relative humidity. If your mother has a humidifier going this may make the air so moist that condensation and mould may form. This problem will get worse as the outside temperature goes down. Get a humidity tester and see if the air is dry or damp in your mothers home. Many hardware stores have inexpensive humidity guages that hang on the wall.

If the air in the home is moist then putting in brand new windows may even make the problem worse, because there will be no place for that humidity to escape.

Hope this helps
