Forum Title: Window leak?
I moved into a new construction home a month ago and noticed this (see attached pictures) during the last two thunderstorms. In picture 1, I'm standing inside the house and put a circle around what I presume to be a leak in the window. That is the outside pane where the bubble of water is. In picture 2, I'm standing inside the house and put another circle around what I presume to be a leak in the window. Again, it is the outside pane where the bubbles of water is. For someone who knows more than I do about windows, are they leaking and do I need to have them replaced? Thanks.

Welcome to the forums Jed! How about a pic with the door open - the fix might be as simple as adding new weatherstripping.

Thanks Chandler. All of the windows on the house are single hung double pane windows, except for a large double pane window in the kitchen and another large double pane window with privacy glass in the bathroom (which doesn't let me see if there is a leak on it). I took the pictures from the first post during a rain and that gave me all the water on the outside pane of the window. The pictures attached to this post are an outside/inside of one of the windows having problems, an outside shot of the large kitchen window, another picture of the leak from the storm, and last a picture of the window when dry. The blue tape is everywhere I was seeing the leak.

I've read this a couple times... but don't see anywhere where you say that this leak is causing water to enter inside the home. Depending on how the glass is glazed into the sash, what you are seeing may be normal. Most vinyl window sashes have a weep system that lets any water back out that gets into the frame. The interior side of your sash looks like it is welded, so it would seem to indicate that you have exterior glazing stops on those windows, which means that the glass is sealed (either with two-faced tape or wet glaze with silicone) to the INSIDE of the frame, whereas the glazing stops are not 100% weather tight since they have to pop off the outside in the event that the double pane insulating glass ever needs to be replaced. They are usually dual durometer, which is just a fancy way of saying the glazing stops have 2 rubber fin gaskets to help keep water out. I've been working with vinyl windows since 1991, so I think what you are seeing is normal and nothing to worry about.
