Support the ceiling of the garage using some lumber. Pry on the crowbar to lift the trim and loosen it. Use a hammer to tap the 2x6 to a vertical position where it ll raise the header and release the downward pressure on the rotted post. It is a good idea to sandwich 1 2 plywood or osb between the pieces of 2x dimension lumber.

Garage doors typically don t require much in the way of regular maintenance but one problem that is not uncommon is rotting door jambs. Door jambs are susceptible to wood rot due to their exposure to ground level moisture. Lay one board on the garage floor to act as a sill plate. Insert the tip of a flat crowbar under the trim.

Take down any trim or any external pieces of wood which are not part of the garage door header. Stand the other 2x6 on top of the sill plate and slip its upper end underneath the header that spans the garage door opening. If any portion of your garage door header has rotted or softened due to water exposure you need in replace the entire header.
