bad stucco terminations

Seems like eight out of every ten stucco homes I look at has improperly teminated stucco at the bottoms of the walls (and all penetrations). No weep screed or flashing of any kind. You just know it’s going to suck up snowmelt and delaminate. What’s the fix after the fact? -Kent


How far off the ground/roof is it? I would be more worried about kickout diverters and window/door/flashing installations. Imo the weep screeds do a job but they are over rated. If the moisture barriers are installed properly the after the fact should not be a problem. But there are other things ASTM and AAMA says that I disagree with anyway. That edge is referred to as 66/caseing bead/stop It has worked fine for many years it has holes in the back edge within 1/4 inch from the bottom.

When it is put on the wall it needs to hang down 1/2 - 3/4 inch to form a drip edge. It can weep out the back and the front edgde is only 1/4 inch high. With the moisture barrier down over the edge of the sheathing and the 66 hanging even lower how can it be the issue they are makeing it out to be?

Carl, the bottom of the wall varies from two inches above grade to six inches below, with most of it being below. That’s why I expect it to wick up moisture. We get heavy drifting here that melts over months.

Talked to a stucco guy yesterday who says he holds back the scratch and brown coats around doors and windows, runs a bead of caulk around them, then runs the color coat up to the trim. In this case it would appear uncaulked but would actually be caulked and calling it out would be a mistake. -Kent

Below grade is a no no! As for caulking the windows most mfgrs. call for a backer rod an sealant joint. Not a filet joint. What kind of windows? The stucco guy is looking for trouble if anything ever goes to court.

#5 good illustration and lesson learned for me. I virtually never see this type of installation, installed a ton of windows over the years and never used this detail. Thanks Carl. -Kent

You are welcome. Around here the instructions are on most every window and the carpenters or someone pulls them off.

If they would incorporate that with these flashing details I would be happy!

Then these problems would not happen!

But when the are lathing them with paperback lath like these the window installations do not really mean alot!

Then when someone trys to do something about all of it they get told this crap!
