Plywood sheathing gap

sbkim

Hello and I apologize for such basic question. How much gap is normal between sheets of plywood sheathing for exterior walls? I've heard 1/8" Our framers have done great work so far but in one area where the window size was reduced, I can see about 1/2" gap but covered by Tyvek. I think I am just being paranoid but should I ask them to re-do this or just put silicone over the gap? I just don't want to use anything that might cause the plywood to not expand and eventually bow...

Many thanks!

Post a picture.
If this gap around a window opening or in the field?
If this is a butt joint 1/2" is way to much.

Absolutely - should have done from the beginning.

Just point it out to your framer. He'll likely just add a block below the top plates, which is fine.
