I recently salvaged several fixed glass Andersen windows from a jobsite where the owner wanted to change to remote opening (a contemporary design left the windows 8 feet above the floor). One of the windows leaked. While removing the window, the only obvious signs of leakage was the black mold on the rough sill…no rot, no wetness. I’m assuming a slow leak. There is a peice of plastic trim loose on the bottom exterior edge of the glass. Has anyone tried to dissassemble a 10 year old Andersen? This puppy is 4-0 by 5-0 so I really want to use it!

Good luck about 95% of Andersen fixed glass I have had to replace breaks trying to get it out. Best advice is get a thin bladed putty knife, heat it up in a flared nozzel heat gun and work very slowly cutting the silicone.

If the walls & ceiling had poly for a vapor barrier the area around doors and windows is the only place for vapor to escape, could be the window is OK. If it was on the rough sill could be a bad flash job, what about the finish sill?
Sounds to me like the moisture is from a poor instal or from condensation.

I think the install was ok...the ro was wrapped correctly in bichuthene. The bottom of the window frame had the same black mold even though it it was shimmed and not resting directly on the sill. My guess as to why there wasn't more water is the aspect....away from prevailing winds and storms. I'm still not sure how this house breathes.
I'm building my own house on a shoestring so I think I'll flip the window, caulk the heck out of it and make a drip pan on the ro to dump water into the drainage plane. Still WAY cheaper than buying a new window and rebuilding the window sounds sketchy.
That's doable. When you flip it, change the metal retainer clips around. The ones on bottom and two sides are intended to create a spacer while the top ones are flat. Change the top to bottom ones with each other..
