Installing vinyl siding over existing wood

I have a 13 year old home and the entire house has vinyl siding, except for the bay window, which was put in after the fact (they forgot to put it in). Now the wood is starting to split and rot (cheap wood of course). I'm thinking of putting vinyl siding on it and was wondering if it was okay to put the siding over the existing wood or should I rip off the old wood and install the weatherproofing material and then the siding?

Thanks.

Welcome to the forums! Applying vinyl over an extisting siding will cause elevation problems when you get to your brick mold on the window and on the corner molding. It will protrude past it, and look funky. It would be best to remove the old siding, install OSB if it already isn't there, and apply Tyvek and siding over that.

The old siding may not look the same as the new because of fading and "planned obsolesence".

You always need a moisture barrier under the siding because it really not a waterproof barrier (it only sheds normal rain, except at the vertical joints and the channels at openings).

White cedar shingles

H

hrjrkr on Apr 11, 2009

I need to replace the shingles on the south side of my house and they are white cedar. I've been told that white cedar is not worth to put back on. They say to use red cedar but I'm affraid that it's not going to match the rest of the house and the price of red is almost 3 times the cost of white. Any comments? Also I bought a bundle of white cedar ($40.00) at the big box store and it came with a information pamphlet that said you have to space them 1/8 " to 1/4 " apart. Again I was told that white cedar shrinks a lot. So do I space them according to the instructions or butt them tight so when they shrink there won't be a 1/2" gap between them? ThanksRead More

How to finish after a very big repair

J

johannamarie on Apr 19, 2009

I've been searching through old posts, but can't find answers to a couple of things. We've just gone through about a four-week repair done by professionals (foundation and water damage problems on the south and west sides of the house). The stucco from the south wall was completely removed, so we had primed Hardiplank installed there (nice improvement-added insulation, plywood shear wall, and Tyvek). The front of the house is already siding, so it looks fine. Only the bottom three feet of the stucco had to be removed from the west (back) wall, so we had that repaired. Now for how to finish it, which we'd like to do ourselves if possible. Things I'm confused about: 1.The stucco people said elastomeric paint is best. Do we use that only on the stucco, or can we paint the Hardiplank with it, too? 2. Everywhere I read that new stucco should cure for 30 days, but they said this has some sort of acrylic in it and doesn't need to cure. Won't it cause the paint to fail if we paint it too soon? 3.The Hardiplank is caulked where it meets any trim, but not where two pieces meet each other along the wall. The contractor who did the job is so good I figure that must be how it's done, but I just wanted to check before painting. Is that right? Thanks to anyone who can point us in the right direction here. We don't want to do anything that might mess up all the good work that's been done.Read More
