> evaporate ... likely to make the problem worse

Correct, evaporating the water isnt the solution but rather part of the problem. Humid air hitting the cold glass is what causes the water to come out (cold air holds less water than warm air so as it cools some has to come out). More heat does not change the amount of water you have in the air so condensation will stay. You either need to lower amount of water in the air (dehumidifier) or you need to not have cold glass (isolating layer or double glazing). Ideally youd have a bit of both, lower humidity in combination with windows that do not waste as much heat will significantly increase quality of life in general and heating cost (dry air needs less energy to heat up than humid air).

Sadly, where I live the outside humidity is even higher than indoors, so running ventilation fans inside only increases total humidity as that air gets replaced.

Edit: if it’s sufficiently cold out, the rise in temp when the outside air warms up can make the ventilation idea work at higher humidity levels, but in Houston this still doesn’t work out very often

From that exact same page:

>Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath.

>In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.

>In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies.

Thanks for proving me right. I appreciate it.

The house is brand new. I probably should've mentioned that. The finished spackling looked great the day I looked at it. The walls and all corners were sharp and ready for paint. I sent the realtor a text telling her to let the contractor know I wanted SMOOTH ceilings and walls, none of the texture crap.

As luck would have it, she did not relay the message for a day and a half and they sprayed the ceilings and walls with this crap the prior day (literally hours after I checked on the progress). It would've cost me to have it all redone at the time AND add to my already delayed closing date. I kinda had to bite the bullet or the wife would've killed me.

Do I need to do prep work on the ceilings before going with 1/4" sheetrock or can I just screw it on, spackle, and go about my life?

if your frames are aluminum, know that some window frames have "weeping holes", - they are small slits that allow the condensate to drain to the outside. those sometimes clog up or the glazing unit seal material slowly melt/ooze and clogs tuem up. Usually you can clear those holes with a straightened paperclip, and the condensation will not pool or spill over to the interior.

As otherd have suggested, you may decide to dehumidify.

They exist, but affects on humans have never been proven
