We have an approximately 80 yr old house with wood lap siding. No gutters were ever installed (we will be fixing that). Since there are no gutters rain water falls and splashes up onto the siding. There are areas of siding that are now rotted and the paint is peeling badly (just painted a year ago by previous owners). We want to replace the siding with Vinyl. My husband (and his friends, one of them a contractor) think that we can just put up this foam board stuff and install the siding over the top of the old, rot and all. I said that although we cannot afford a complete tear off, we have to replace the rotted sections with new wood BEFORE going over it with new siding. Who's right?

The rotted wood needs to be removed, but can be patched inexpensively with OSB sheets to match the depth of the rest of the siding above. Leaving rotted wood under vinyl is a good way to encourage a termite problem. Rot has a tendency to hold moisture, can lead to mold, and will actually spread in time. Also, it is important to have a secure surface to attach the bottom locking strip for the vinyl. It is probably the most critical piece you will put on the house and establishs level siding installation.

Even though vinyl resists water penetration, it is important to have a good moisture barrier behind it. Also, install some gutters. Water will still splash up on the vinyl and can work its way into the bottom panel.
