Yes, this is normal as Pella vinyl products have four corner welding. When you weld a corner, the process does create an area of excess vinyl. Our manufacturing process does take steps to trim this off, creating a similar look on all corners. The strength of the corner weld comes from making sure that these surfaces are fully welded together, so care is taken not to trim too much excess vinyl away - creating a weakness in that area.
Replacement parts for your Pella products may be obtained from the place of purchase or your local

. If you feel service is required, the Pella representatives can also schedule a service appointment for you.

While windows and doors do not cause condenstation, they may be one of the first places it shows up. For more detailed information,
