Attic

The floor rim joist was damaged from a sprinkler that sprayed on the stucco wall for many years. The stucco was badly damaged and showed signs that there could be further damage in the framing. Only after the stucco was removed could we verified this.

The rim joist, holds up the wall, which holds up the roof. On a two story home, the rim joist is carrying the weight of the wall, the second-floor, the second-floor wall and the roof. I hope you're starting to get an idea of how much weight can actually be supported by a single rim joist.

Repairing the rim joist can be dangerous and should only be done by an experienced carpenter or contractor. Make sure that these building professionals have experience and understand how much weight they are dealing with.

Some of the damage to rim joist will create structural problems. Let's say for example that you have a 5 1/2 inch rim joist. Termites have been working on it for quite some time and it is now 4 1/2 inches. The weight of the exterior wall is applying pressure to the damaged rim joist, causing the wall to sag.

To repair this problem correctly, the floor and wall will need to be raised enough to replace the damaged rim joist with a new 5 1/2 inch rim joist. This kind of structural damage should be repaired my professional.
