Rim Joist Repair

I have a rim joist that has some water damage and a few small areas of rot (which lead to some carpanter ants) due to a previous owner attaching a deck ledge without flashing. The rim joist is still in good enough to brace the ends of joists.

I have added flashing to the ledger to stop water infiltration.

What would be considered an acceptable fix for the rotten areas?

Thanks

Couldn't say without seeing how extensive the damage is.

A lot depends on your nit-pickiness and the accessibility of the rim joist.


I am picky enough to seriously consider the following IF the access was adequate:

Go under the joists and set blocking/bridging to hold the joists in place.

Get a SawzAll with a 12" rough-in blade and cut off the rim joist nails.

Attach a new rim joist, perhaps using screws and plenty of caulk. Keep your sledge hammers nearby.


OR


Temporarily attach scrap blocking to cover each side of the damaged areas.

Drill a hole in one block of each pair, I can't say if top or bottom is the better location for the hole. Inject Great Stuff foam.

Remove the blocks in a few days.
