:107 Insect Exclusion

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:107 EcoTip: Stucco weep screeds frequently leave gaps between the foundation and the screed. This can permit insect entry.

A properly installed weep screed will allow moisture to drain but exclude insects.

Additional Information

Suggested Review – :106

The weep screed should be sealed to the foundation so that the only openings are the weep holes that permit water to drain. These weep holes are designed to help exclude insect. What needs to be sealed is the gap that may be present between the weed screed and the foundation or stem wall of your home. I’ve seen these openings be large enough to insert ones fingers (scary thought). The sealant should be a silicone elastic caulk material that can expand and contract as conditions change. It should be checked every year to be sure it remains in good condition. This is usually best accomplished by using a mirror to give you a better observation angle.

When applying the sealant, it may be helpful to apply painters tape to cover and protect the weep holes from becoming clogged with sealant. Once the sealant has been applied the tape is removed to uncover the holes.
