basementcondensation
Freaking out here. Just had a second coat of mud put on the seams in the basement drywall. Went down to close up some of the vents because my guy is going to sand tomorrow and noticed a bunch of condensation on the windows frames.
I had vents added right in front of each window to properly heat the basement. Not sure if that is the cause. Or if it is just because of all the moisture from the mud added to the walls.
Any ideas on why? Or how to fix this?
Did the flashing repair involve removing/re-positioning the exterior trim/siding/sheathing?
If so, the simplest scenario might be due to the insulation being disturbed/removed.
You can check on the inside by moving a burning incense stick around the trim and window, which should reveal air movement. If you find a "windy" area, remove the interior trim and add low E foam (low expansion) if there are any air leaks.
I realize that you don't want to proceed with the project but I thought I'd answer anyway in case someone else is curious. I am a licensed contractor and my company specializes in basement remodeling; we have done several window expansions or additions in concrete foundations. A few things:
Though you can support the new opening with pressure treated wood (according the engineers prescription, of course), most likely the engineer will recommend a steel frame in the newly cut opening. We use a 4"x4"x1/4" steel frame that the engineer signs off on. You can have one made to fit your opening at your local steel fabricator. (see pic below)
After you install the frame with bolts into the concrete and silicone sealant around the entire perimeter, the installation of the window is a piece of cake.

You are probably seeing condensation of moisture from the drying of the drywall mud. Give it a few days before sounding the alarm bells.
If you are concerned about the short term humidity increase in that area you could consider running a dehumidifier in the room for a few days.
