Tom, my son-in-law foam filled the weep holes on his house. i told him it was a bad idea. Can you tell me what the cosequences are for doing this?

Tom: Who knows? It’s going to build up water; they’re there for a reason. Why would anybody undo something that’s put there for a reason, I don’t understand. A lot of us have strange ways of extrapolating certain situations. As far as that goes, you’re going to get water behind the brick. It has nowhere to go, it won’t dry out as quickly, and you get the moisture issues in a wall, which is never a good idea. Especially when we have very wet, rainy seasons. This year seems to be like one of those; it’s very extreme this year.
Charlie: They’re down in Friendswood so its…
Tom: I’ll let you this. It’s lucky because even if; actually it’s not lucky. If it’s an expandable foam you put in there and expand it up high on the brick, you can’t even get it out now. You can’t undo the problem, because that stuff travels all over. A good weep hole is put in without a brick right there. They keep scraping and scraping as the mortar falls. When the job is done then they put a brick right in there with two little weep holes on either side. That way all the mortar channels the water to that one spot. That’s exactly how a weep hole is supposed to be manufactured, or created during the building process. It’s not done as much as usual.
Charlie: But not in that house anymore.
Tom: It wouldn’t matter now. Spray that foam. Probably just want to keep bugs out or something.
Charlie: There’s nothing you can do though.
Tom: I don’t think so,no. He messed it up.
