I noticed there is a 2" screw in the bottom of the track on each of my Andersen windows that were installed side by side to each other. I suspect the screws should not be there since it would allow water get into the screw holes before discharging out from the weep holes.

What could be a possible reason for the installer to do this? Could I remove the screws and patch up the hole with caulk or epoxy or do I need to have the window reinstalled?

  • Are you sure they're not part of the window? They don't look like something an installer would've put there.

  • I don't see any screws on the track for the other individual windows. It's only in this set of windows that were installed side by side to each other.

  • Are there other windows in conjoined groups?

  • Do you mean the individual ones? No, they are on their own and not installed next to another window.

  • Are these only on the joint between the two window units or are they also on the outside edges? (i.e. is there another window just beyond the jamb we see, or is the other window behind you as you took this picture?) My gut instinct is that these should not be there. If it's a recent install, it should still be under warranty - call the company that installed them and ask for a supervisor to come check it over because you have some questions.
