Customer Robin calls me, says the vinyl siding has nothing behind it in places. I investigate. The window sills were either flat or sloped TOWARD the house, forcing rain water to run into the walls. The vinyl siding did not let the water evaporate, so the water rotted the walls and a good portion of the floor framing. All three walls needed to be removed, as well as the outer portion of the floor framing, including joist ends, band joists, and sill plates. I added “sister” joists to most of the joists after removing the rotted ends. I installed sill plates. The walls were reframed, windows and vinyl siding re-installed. Some of the pictures show the roof of the room being supported by “stiffbacks”, after I jacked up the left side about 2.5″. This job shows the kind of damage that water can do if allowed time to do it.
The detail pictures show the 10 degree slope of the window and lower band sills, and the drip grooves in both, which are essential in order to keep water from running laterally back toward the house. The grooves cause rain water to bead up and drop to the ground – outside the house.
The moral of this story is to fix water ingress as soon as possible, because water will decompose the wood structure of your house. The vinyl siding on this house hid this decomposition from my customer, and she did not discover the damage until one day she happened to push against the vinyl siding, and it “gave”.
