What do you think of the way Pella windows come from the factory with their flanges that stop short of the corners, not over lapped to prevent water entry? They send them with little pieces of self stick foam that are supposed to keep them dry, but they are often torn or stuck to themselves. Well I found an easy fix today. My boss had ordered some lengths of “flange” from Pella. We needed them to repair a couple of windows that had been installed without any flange at all. I started to put the flanges on in the same fashion as they came from the factory, when I realized that all I had to do was to overlap the sides like you do when installing Anderson flanges on their sliders. You need to trim a small bit of the flange that sticks in the window groove, but it only takes a second. Although a dab of caulk is still a good idea at the very corner, I feel this method is ten times better than just a piece of tape over the corner. Simple, and I wonder why Pella doesn’t do that on their own?
