Inspected a house today with what I believe is EIFS, tapped on it and it sounds hollow. The last time I tried that trick, I was wrong per the contractor who came out and complete the needed repairs. He stated it was a DEFS system and it didn’t need a weep screed.
Today’s inspection has either DEFS or EIFS, sounds hollow, but has no weep screed.
Is there an easy way to tell the difference? I read that if there is housewrap then it is DEFS, not sure if that’s true or not.
