One of the joists in my garage is getting beyond saving and starting to sag so it needs replacing. Its a pair of 3x2s on a 2.7m span so maybe a little under sized too. Ideally I'l replace it with something stiffer. The problem is the slot for the timber is only deep enough for the current sized joist. I can't enlarge it and I don't want to disturb the roof, which is likely to be asbestos.
Currently considering three options:
1. replace it like for like except pressure treated this time
2. replace it with one identical bit of timber then sister a shorter bit of 6x2 to that piece with coach bolts
3. thin down the ends of a bit of 6x2 so they will slot in the notches
Any thoughts on these or other solutions?
