Rotten Rim Joist

First, you have to address the source of water that is causing the damage. Without seeing the site it is difficult to fully address your questions accurately, but rim joists can be replaced. Typically the floors josts are tempory supported and the rim is addressed from the exterior. It is also important to assess whether the mud plate and studding in the area is affected as well. It would be best to post this project on the site and have some with experience come and assess the project .

Hi Glenn, thanks for your reply. We do not have access to the rim joist from the exterior unless we take down the brick. So we are trying to replace it from the inside.

Another question for you... we've noticed that we can see the back of the brick from the inside of the basement. There was a vapour barrier of some kind between the brick and house but with all the water damage it has fallen apart. Is this barrier required? What would happen if we don't replace it?

Thanks!
