Question DetailsAsked on 5/2/2017

Can I replace the center post on a 2 car garage without having to remove the garage doors?

backed into the center post on my 2 car garage. Now the center post has to be replaced. the post with the garage doors just kind of slid back in the middle. the post sits on top of the slab with no fastner or post bracket. can I replace the post with out taking the garage doors completely off because the estimate for taking them off then re install is pretty pricey

Here is a previous similar question with answer, if the post was not significantly damaged:

Yes you can usually replace the post with the door in place and fully open - if it does not open fully, exposing the top of the post enough, you might have to pull the emergency disconnect and push the door further open (all the way back to the opener, for instance) and tie it off there until the repair is done, to fully expose the work area.

Where it gets nasty, and the door might have to be removed, is if the beams moved and damaged the axle shaft for the door, and sometimes the rare cases where the beams come into the side of the post rather than the top so you cannot get at the top of the post area without removing at least the axle and springs and travel beam mounting bracket on the opener.

Of course, the supporting beams have to be properly supported by temporary posts during the swapout, because the center post supports not only the beams but the wall and floor and roof loads coming down through the wall or the floor joists onto the top of the beams.

And of course, that center post should be properly fastened to the floor - normally with a concrete-anchor U-bracket (anchored into the concrete, with U-shaped bracket sticking up that the post fits into and is nailed/screwed to. On a retrofit like yours you can use Simpson angle brackets or such around the base to nail/screw to the post and concrete-anchor into the concrete. Ditto at the top - usually fastened in with a Simpson type post bracket like this - the top is fitted around the beam and fastened, then the post fits into the bottom -

This is just an example - come in many strengths and sizes, most places that carry them have the catalog near the bins showing which works for which application.
