Joist repair by previous owner - floorboards unsupported at one end
Anonymous user 03/03/2024 - 3.21 PM
The previous owner has had some repairs done to a floor joist, but it looks like it was replaced with a smaller beam - there's about 4 floorboards are unsupported at one end and bow when stood on. Pictures: https://imgur.com/a/lmYqdCk Am I good to just glue and nail/bolt an extra piece of wood on the side and bring it up to level for the boards to sit on? Or is this more involved and I need expert support?
Are you a tradesperson and able to answer this question?

Bolting on the side is one way of doing it, I would suggest using quite wide joist so at least 2/3 of it is overlapping the existing joist.

Yes, I would recommend piece of timber bolted to the joist so the floor boards are sitting on something solid. You can use a 4" by 2" timber and ideally use 100mm "timber lock" screws in M10 thickness to join the two timbers. These will make sure the timber doesn't become loose over time through usage. Then simply screw the floor boards to the new timber.
