Unhappy Water leak from corner of the house and controversial suggestions from pros

Would LOVE an advice from other experienced folks.

While exchanging our carpet for hardwood, we noticed a moisture and ripped through a drywall to find moisture and soil.
We did open up a drywall immediately and asked contractors to come in for a quote.

[Where it's leaking]
Corner of the house on ground level where 2x4 merges at the corner. The concrete slab and outside soil is equal in height (thus working on proper drainage at this point)
Exterior wall is stucco and multiple small cracks is seen where leaks are happening.

[Solution #1]
Since the drywall is out, seal with silicon based filler from "inside" between 2x4 and stucco, then seal outside with silicon as well.

[Solution #2]
Rip out the stucco, and patch up the area.

Since the damage is at the corner, we are concerned about structural rigidity since the house was built in 1952.

What would you do? The house is in San Francisco, and being a first time buyer, I would like to save cost, but not cut corners. Is #1 sufficient? or is he just not wanting to do small project?

Thank you!

Welcome to the best DIY forum on the Internet!

This is totally out of my area of expertise but I can tell you that the people that DO know are going to want to see some pictures. Pictures need to be well-lit and in focus to be useful. More pictures are better than fewer and both close ups as well as from a distance will be needed. Don't forget to include outside as well.

It is best to upload high definition pictures to a photo hosting site such as photobucket.com or imgur.com and post the public URLs here. Do not attempt to use tinypic as the forum rejects it.

No form of seal is going to work.
Really need that picture.
The grade really needed to be at least 6" below that stucco.

Is that part of the exterior exposed or is it under the dirt? As Joe alluded to it needs to be addressed from the exterior. http://www.doityourself.com/forum/el...your-post.html

It sounds like the grading outside the house is too high. Like has already been said the fix needs to be outside. Water has a nasty way of finding it's way in. There are two constants; water never gives up... and it flows downhill. The grade must be lower than the wood. I like to see a absolute minimum of 4" of foundation above grade and prefer to much more to help prevent splashing water from wetting the bottom of siding or the junction between the wall and foundation.
