And I know how to SNIP


I have a 4 year old house where the back door (Pella steel) leaks on the bottom corners. I can see the water on the wooden rail on the threshold and seems to only occur on the two corners vs the middle. The weather stripping is wet on the bottom half of the door where the door compresses into it when closed and the corner pad is completely soaked. Doing a visual inspection the seal when the door is closes seems tight (except the top corner on
the knob side shows some light). Can you give any advice on what to check/try?

Call Pella.
