I'm about to level some floor joists but I'm just deciding whether to add noggins before or after sistering new 4x2s onto them. I'm edging towards before because I'll only need shorter joist lengths and they'll fit in my van lol. Also I'll be able to add 6x2's instead of 4x2 noggins. What do you guys reckon? Cheers.
Afterwards, otherwise it's pointless planting on full lengths and you'll create far more work for yourself trying to get a flat surface.
