I have stucco on my house and it leaks. The building paper was not shingled
correctly, and the staples holding the wire on, were drove too deep creating
holes all over the paper (where it pulled the wire through). I am planning
to tear down the stucco, and install Tyvek, and redo the house with either
vinyl siding or Hardiboard.

I know my walls (i.e. the OSB and some insulation) are wet from a recent
rain. Does Tyvek breath well? Should I be concerned about trapping
moisture in the wall? I live in Canada, so we have a vapor barrier on the
inside of the walls i.e. moisture can only move out of the wall through the
Tyvek.

That is what makes Tyvek such a good material.

Do you have real Stucco or synthetic stucco. In the US there were some
class action suits and people are getting some money from the synthetic
stucco manufacturers.

As far as holes in the paper, there are always holes in the paper no matter
what type of siding you use.

Do you mean the 1" stucco, wood sheeting, insulation, then Drywall
soaked from a rain, I dont think you have an issue you describe, Ive
seen a hundred or so 80 yr old stucco homes. and getting a wet wall
would not be the stucco but something else. If your interior walls are
really wet then you will have rot and mold , which does not happen from
nails going through the paper, look at something else for your problems,
like roof, caulking. gutters, or ground level rain.

There were problems with "stucco" here in Canada a number of years ago.
The problem was that the new acrylic materials were being used in an attempt
to make it moisture proof, which is actually impossible.

The idea was that you can put 1.5" to 2" of foam board insulation on the
outside, then apply a fiberglass mesh and the finish and gain some R-value
in the wall. Trying to make this moisture tight is just not practical, so
water would eventually seep in and begin to rot the sheathing and possibly
even studs.

The method now used is to provide "rainscreen protection" (google that term
for more details). Basically, some kind of protection between the sheathing
and the foam board is needed, and Tyvec or Typar are excellent products.

One or both of these manufacturers make a product especially for stucco
that provides a rough surface that leaves a small air gap behind the foam
board. The small air gap and the barrier provided by the Tyvec or Typar
provide ventilation to allow any water to not cause problems.

Tyvec or Typar allows the house to breath but does not allow air to
penetrate inwards. It is an excellent air barrier material. Many homes
built around here (Toronto area) combine the vapour and air bariers, so
you only see Tyvec/Typar at the ends of the floor platforms. It is
installed go lap to the inside of the walls where it is attached to the
vapour barrier on the inside.

We built our home and used a stucco finish and therefore went with
completely separate air and vapour barriers, so the entire outside of
the house was covered with Typar. The stuff is so good at making the
house air tight that the building inspector allowed us to proceed with
the insulation before the stucco finish was installed. Ordinarily, the
insulation must wait until the outside finish (brick, stucco, siding)
is complete in order to make the building weather tight. A complete
covering of Tyvec/Typar will make the building weather tight.

I read thru most your page. If it were me, I would pay a professional
engineer to come out and show him the info you got on the web page and let
him review the house and write a report. My guess is that the stucco is too
thin and since it has that obvious defect it probably has other major
defects. You are probably wasting time talking to the stucco guy. Check
the phone book and after you have your report find a lawyer who specializes
in house defects. Also find out how much a good repair would be.
Unfortuantely, the contractor may have no money and disappear. The lawyer
may be expensive. Cheapest thing may be to fix it yourself.

Is this a new house? If yes, you should be fighting with the builder and
not the contractor.
