IMPROVING FLASHING INSTALLATION FOR EXIS
Woodpeckers have trashed the cedar-channel siding on my house; it looks like swiss cheese. I’m worried about mold growth in the walls so I’m going to replace the wood with metal siding. If I can afford it Zinc based…..
I’ve had issues with water leaking in around windows and knowing how the contractor didn’t flash the windows corrrectly(no pan flashing at the sills and tyvec was not lapped over the window head fins) does anyone have a solution to reflashing and panning the sills without removing the windows from the opening??
I’ve got marvin aluminum clad windows with nailer fins…
Taking the windows out will be costly, but i think the only way to do it…

Sorry for the bad news, but flashing sorta can't be done after the fact without major deconstruction first.
Oh, and I'm guessing that those woodpeckers are trying to get insects that they can hear.
Support our Troops. Bring them home. Now. And pray that at least some of the buildings in the green zone have flat roofs, with a stairway.
Thanks YesMaam,
My thought was to remove the sill nailing flange, have aluminum flashing sills with upturned ends at the jambs fabricated and slip them in? Maybe involve removing just the jamb casing inside, to caulk and seal???

Once you pull off the bottom flange, you're going to find that the window is sitting ON the sill -- at least in one corner. Lifting it off of the sill (to allow space to slip in your pan) will require that you remove the rest of the nailing flanges -- which probably means pulling off more siding. And so it goes, on and on.........
Like one of the other guys said, you might be able to help yourself with some rubber (bituthene) flashing placed in a well thought-out pattern. But it really won't be the same as on original job done right.

All the siding will be replaced anyway; so remove ALL the fins. I'm a step from removing the window at that point.
Being cheep won't solve this problem again!!
Being said before: "you never have enough tiime to do it right the first time".......

You can do a "sort-of" job of flashing the windows without removing them, but you'll still have to remove some of the nails. The problem is that WHEN the window unit starts to leak thru the miters you will want pan flashing under it. It really is when, not if. I install windows with the expectation that they will leak thru the sills right away, and sometimes it's true, no matter what brand you are using.
Since you will be residing, you can remove the existing siding around the windows and reflash. The precise technique to use depends on the style of windows and some other features, but generally a reasonably liberal use of self-adhesive rubber flashing membrane should work out.
