Supporting rim joist
Posted: Wed Feb 03, 2016 6:24 pm
Hi, I need to repair the rim joist on my 99 Legend. I have 4 sections I know need fixed. They are by the front door, back door, and both corners at the north side. The back door is the worst. It is rotted out over a good 8 foot span. About 4 of the floor joists immediately under the door is also rotted on the last 2-3 inches of the boards. My plan is to sister all the studs together using corner ties and then cut off the outer rim joist and replace it with treated lumber. I am fairly confident I have the leaks fixed but I will also be getting a new roof and gutters this spring anyway.
I have two floor jacks. My only hesitation on this job is the supporting of the wall. I want to make sure I will be supporting it properly. I've read to put a board on both floor jacks and use it to support a longer span across the floor joists. My concern however is the outer wall will sag once the rim joist is completely removed. There is only one board for the rim joist and the outer wall rests half way on the rim joist and half way on the ends of the floor joists. With the ends of the joists rotted along with the rim board my concern is the wall will sag for sure.
If anyone has any helpful information or tips to prevent a structural problem please share it. I have everything to do this job so I'm just looking for last minute advice. I've found I can never have enough knowledge about a job.![Wink :wink:](./images/smilies/icon_wink.gif)
