Window Interior Condensation and Mold
While cleaning my mother-in-laws house I noticed a serious problem with her windows. She had mentioned it to me before but did not tell me the extent of the problem.
Her windows are gathering condensation on the inside of the window. They are insulated windows and are not fogged but the condensation inside is so severe there is black mold on the window frame and sills. You can see the begining of a wood rot issue also. The water literally drips down the window.
I can feel the temperature drop around the window but I can not tell if the air is comming in from the outside around the window frame or if the window is just cold.
She lives in a condominium so there are some association issues that we will have to deal with if the windows need to be replaced. I hope there is an easier solution maybe recaulking or something.

Same story!! If you are running heat increase ventilation to remove RH. If you are running cooling run a dehumidifier.

Your location is N. Florida, is that where the house with the condensation problem is located? If the condensation is on the inside, then the windows are colder than the inside house temp enough to cause condensation. Assuming the house in question is in N. Florida also, then there has to be an awful lot of moisture. Venting as Airman suggested will bring in dryer air, but my question would be, where is all of that moisture coming from?
Here are some things to check for to reduce the internal moisture: Drying cloths inside, cloths dryer not vented to outside (disconnected), fish tanks, tons of plants, dirt floor in crawl space, water in basement or crawl space, water leaks, long showers with no fan (should run for 30 minutes after shower), a lot of people or pets, a lot of cooking. That should get you started.
Pick up a guage to measure the humidity and get it down below 40% and she should be all set. If venting as Airman suggested or locating a source of moisture doesn't help, let us know and we will try again.
