rich graves

mini split, but heat hasnt been on any yet

i was thinking the water could be getting in the screw holes where the adjustments for threshold possibly

Webelieve the door may be the problem because its kinda near the door,  and im had issues with door, I don't think theres a door sill installed also, also when it rains, water sits on the black strip that sits under door , however we haved caulked everything

Anyone on here have a 20ft container house?  mine is getting water inside on subfloor, have already put new floor down, thought i fixed issue, but i believe it could be threshold at door, anyone have any ideas
