I would back out if I were you. There arre thousands of homeowners in the midwest ( mostly Indianna and Ohio, I think) who are joining together agaisnt one major buileder in a class action lawsuit, because he failed to assure that weepholes were used in his homes. The result is wholesale destruction of the underlying wood structure from rot, and unhealthy homes.

The reason is that no masonry wall is waterproof , so water will penetrate it in a blown rain and wich into the back side. A drainage plane is provided there that weeps out to the ground at the lowest level of the wall. Lacking the weeps means that the water is staying traped.

Excellence is its own reward!

The homeowner has offered to pay a professional to come in and put the weep holes in, (assuming there is flashing). Would this not solve the problem? I was thinking we could test that the holes are working properly by hosing water in one hole above or below a windowsile and if it is working properly, the water should come out one of the other holes. Is this a good solution?

This is NOT a solution and a very bad thought to begin with.

First, spraying water on the outside of the brick has nothing to do with what weep holes are designed to address. Weep Holes allow condensed water that forms behind the brick to trickle down and out of the structure. They are not there primarily to remove water from outside penetration.

Second, installing weep holes gives you no bona fide evidence that the weatherproof membrane behind the brick has been constructed properly or that these added-after-the-fact weep holes will actually work.

I would walk away from such a deal....no way to guarantee you will ever have a safe sound home.

After endless research on the internet, talking to two general contractor, one brick mason, a building engineer and the advise received here.... we have done just that - pulled out. Thank you!!!
