Installing vinyl siding over stucco

[Ders]

Hey guys. Got a house that's 2x4 construction with stucco for an exterior finish. Looking to wrap it in 1.5'' of foam and install new windows doors and vinyl siding. Here's the big question do I have to remove the stucco? Or can I strap over it. And how ****** will it be to install said strapping and foam over it if I am able?

Thanks
All input is appreciated

strapping is fine , done all the time . if the surface of your stucco is hard, you may need to use concrete nails , otherwise regular nails will work

I'd remove it, but that's me.

Check with your siding supplier. If they don’t know they can check with the manufacturer.

I would want to remove it, seen a lot of rotted sheathing behind stucco.

Removing it will be your only chance to ever find any rot or hidden issues. It will **** but I would strongly consider it.

Removing the entire stucco coat. Sounds like a job that i don’t want to do. Not ever.
I cut out a piece of metal lathe with stucco to put in an exterior outlet once. The piece of stucco was thicker than a paver, and just about as heavy.

When you put foam on the outside of a house, it is best to use weathermate tape to waterproof the surface. Furring strips or rips of plywood are usually screwed through to the studs if you need nailers. Any decay you have will stop if you make the foam into a water barrier, and nail the siding only into the nailers.

Detailing around the windows and anywhere water gets in has to be effective if you want this to work for you. Zip tape and Weathermate make it easy to get a tight, snug house where your foam really insulates and seals. I usually cut a piece of 2x, and screw it to the sill at the bottom. You can rest the foam on it, and get a good seal there.

Again, rot stops when things dry out. Make it dry and you will be OK. Vinyl siding does not keep water out where it counts.

How old is the house, and what kind of stucco? Newer homes with synthetic stucco that doesn't breath are more likely to have rot, while older houses typically have 'real' stucco that breathes.
