Leaking window.

We are currently having a massive rainstorm here in the Midwest. I noticed that one of the first floor windows which is a fixed double pane Pella is leaking at the top. I can't determine at this time if the leak is where the panes attach to the frame or above at the drip cap.

My question is, if the leak is in the window seal itself, how do you repair/fix that seal?

Thanks for your help.

You say it is leaking at the "top". But where is the water coming from exactly- from the casing edge, from an extension jamb seam, around the glass, or from the interior edge of the window sash (the part that would open up if it was a casement)?

Some clarification would help. Most leaks come from water getting behind the nailing fin, which means water is coming in above the window somewhere. So you might also explain what is above the window on the exterior of the home and what type of siding you have.

The window is approx. 4ft x2ft fixed pane (does not open). The water is coming in thru the interior weep holes at the top of the window. The exterior siding is stucco with no brick molding. There is a drip edge at the top of the window. The house is about 7 years old. I was able to staple a rubber membrane over the top of the drip edge last night. This appears to have stopped the water from coming in. It leads me to believe that the leak is at the seal between the window glass frame and the window frame itself (imagine a roll out casement window that doesn't open). The leak started only with this rain storm, had rain about 3wks ago, no leak.

This leads me back to my original question. I'm assuming the casement seal has failed, possibly do to freeze/thaw cycle. How is this fixed?

Let me know if more info will help.

I know of no window that has interior weep holes anywhere, let alone on the top of a window... what would be the point of that? Weep holes obviously should drain to the exterior and they are usually on the bottom of the window. It's not unheard of to have a window that someone installed upside down and/or backwards.

If you have a digital camera, you could take a few photos of the window inside and out, and a closeup of the area where the water is coming in. You can upload photos to a file sharing website like photobucket or yahoo and then copy and paste the link here. Maybe we'll be able to ascertain something from the pictures.
