One of the most frequent questions we get asked when explaining how stucco is installed is “What is a weep screed?” Homeowners—whether they own a stucco home or want to add stucco to their home—should understand how their exterior system works. And no stucco system is complete without a weep screed, the material that allows water to drain out of the wall above the foundation.
What Is A Weep Screed?
A weep screed is a piece of metal trim found at the bottom of the stucco wall. It should be used in every stucco installation and it serves two very important purposes:
1. holding the stucco in place during installation, and
2. allowing moisture to drain from the bottom of the walls.
Without it, moisture has no exit path from behind the stucco. Water could then collect behind the wall and cause the growth of mold and mildew. This leads to rot and stains–eventually on the interior of the home!
Don’t Block the Weep Screed
As mentioned earlier, the weep screed allows moisture to escape from behind the stucco walls. The same problems that occur when it is missing can occur if it is blocked. If there is something getting in the way of of the moisture’s path (i.e. stucco extends below grade or concrete is installed in front of weep screed) there will likely be moisture problems.
If you are having a patio slab installed at your home, make sure the contractor understands not to block the weep screed. Make sure the slab is angled in a way that prevents water damage.
