Hello. Anyone have experience with old carriage house doors? It seems my 129-year-old carriage house sliding doors are not what they used to be….. over the years these doors have drooped and sagged so they no longer meet in the middle like they should. It is obvious that the hanging bracket they roll on has sagged because of the weight of the doors. A foundation specialist told me that in order to remedy this they would need to jack up the building on both sides of the door and replace the sill and the post supporting the sill in order to align the doors. We do not want the building jacked up and would like to try something else.
Does it sound feasible to just lift up the doors and run a very long 2x4 under the area the door will slide on (sort of like a track) and then remove and realign the hanging bracket. I think the 2x4 screwed into the existing wood flooring would be more than sufficient to support the doors and act as a sill plate.
If anyone has any experience with this sort of thing, I would appreciate your recommendations.
