Thanks for all the info. found in these posts. This is my first time posting so let me know how I can improve. Couldn’t find anything in the archives. Just like to get some opinions that you guys are good at.
20 year old 2 story home. Originally 2 block columns supporting the girder. 2x10 attached to bottom of girder to support the floor joists. Through the years additional blocking has been added to the bottom of the 2x10 to correct the sagging joists that has left a noticeable hump throughout the first floor. Seems to me any concentrated loads on a joist that doesn’t have the “proper blocking” would fail as in the past. The band side of the joist has similar ledge with no apparent settling or repair work (sorry no picture). My thought would be joist hangers along with the proper blocking/bridging and DBLing of joist where needed. Owner had someone look at it before putting it on the market and was ok. Buyer is having it evaluated and can live with the hump but she does have a big piano. Thanks for any info.
