we have badly constructed wall (my guess is that the tar paper was not applied correctly under the stucco, and/or around the windows), that leaks water into the house when it rains. it has been like that since we did the remodel four winters ago.

I tried caulking around the windows, and spraying a cement sealer (do not remember the name) to no avail.

What would you recommend short of tearing down the wall and rebuilding it?

My daughter is being treated for leukemia, and doctors say we cannot do any sort of construction in/near the house, on the other hand, we need to repair the leak and resolve any fungi/mold issues which might kill her now that she has highly compromised immune system due to the chemo.

are there any sealers that might work better in this situation?

is it possible to do another layer of tar paper/chicken wire/stucco on top of existing stucco? if so, how do you seal around the existing window?

whatever we do, had to be done externally, no dust, and has to be very affordable, as we are all out of money.

thanks,
