I’m looking to get some advice with sistering some deck joists. Usually I know you don’t want to sister mid span, however where the joists have hit the header are almost completely rotten out (just end rot for about 1 foot) the other supported side is in great shape however there is no external support as it sits on the interior sill plate though the crush glass stucco of the house.
The sister will be connected to the original joist coming out of the house with construction adhesive and peppered with 3” galvanized nails. It will have about 5-6’ of overlap and then a 1 foot section of the original rotted sister cut out before handing on the next support header. I’ll ten scab in a chunk of wood where the existing original header chunk was completely removed.
Will I be okay to cut the 1’ of rot out of the bad end and sister to one side a 8’ length with construction adhesive and lots of nails to make this repair and be confident it will correct the issue?
