|In response to Re: Basement Bathrm. fan vent - through the joist or though the wall?|
If the joist bears on the foundation wall along its entire length, a 3" hole should be OK. If not, as a general rule (meaning consult a structural engineer), the hole should be in the middle third of the joist's bearing span.
: Thank you in advance?
