Need some back up, .. New construction residential (hardy board and hemlock accent) , should I pressure wash Uncaulked (for time management) or caulk first (Ext.trim-caseing-facia) then pressure wash. I am concerned about the water going into joints and probably causing a mess, Wait, I think I got it , ,:vs_coffee:

Caulking is not the weather barrier. The siding, trim, windows, etc are (or are supposed to be) flashed properly to prevent damage from water.

If you find yourself at any time using caulking to stop a leak, there is a larger underlying issue.
