Brandon Whitmore Posted June 2, 2008 Report Share Posted June 2, 2008 My morning house had LP panel siding originally. They installed Tyvek over that material and installed the vinyl over the Tyvek. My concern is that the original windows were installed behind the original panel LP so there is no way to properly flash the windows to the new membrane. I pulled a couple of the viny pieces off at windows and found that the installers left about a 1" gap between the Tyvek and window frames, and of course there is no flashing anywhere around the windows. Since vinyl siding leaks, my concern is that now water is going to seep onto the LP sheathing and rot out the wall. I am sure most of you have seen this-- what do you usually recommend? There is of course the other typical retro fit installation defects with the new Tyvek where it does not run all the way to the base of the sheathing, where the sheathing (LP siding) is visible at penetrations, etc. Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted June 2, 2008 Author Report Share Posted June 2, 2008 After thinking about it, I am going to recommend they install the flashing as would be installed on retro- fit windows without a nailing flange. (bottom followed by the sides, followed by the top with a Z metal under the top piece to try and kick as much water out as possible). Any other suggestions or ideas?

Home Pride Posted June 2, 2008 Report Share Posted June 2, 2008 It's been my experience that siding installers do whatever they want, no matter what recommendations someone else makes. You can give them a copy of the Install Guide from the vinyl siding institute, but I doubt they would read it. Dom. Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted June 2, 2008 Author Report Share Posted June 2, 2008 Yeah, thanks Dominic. Since this is something that I am writing up as a defect in the report, I figured I would point the buyer in the right direction. Hopefully, they will have their own contractor do the work so it gets done right. Link to comment Share on other sites More sharing options...
