:108 Clear Weep Screed

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

1:5:10:108 EcoTip: The weep screed needs to be clear to allow drainage of any water that unavoidably enters. There are many ways the weep screed can become clogged. I have seen some houses where the stucco was never cleared after it was installed. Plants growing too close to the house may grow up into the holes. Even the careless application of caulking material can block the holes.

 To clear the holes you will need a mirror and a piece of coat hanger or other thin stiff wire and a stiff putty knife. If the original plaster is covering the holes, you can usually run a putty knife along the bottom edge which will knock off the plaster. Any holes that are blocked can then be cleared by carefully using the wire to remove the blockage. Don’t ream it around inside the wall cavity or you may damage the open cell foam insulation that is present.

Once the weep screed is clear, do your best to maintain it that way by following tips :105, :106, :107

:107 Insect Exclusion

Filed under: :107 Excluding Insects — Tags: , , , , , , , , — John Banta @ 1:01 am

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.

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.

:106 Debris Around Foundation

Filed under: :106 Foundation Debris — Tags: , , , , , , — John Banta @ 12:01 am

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

1:5:10:106 EcoTip: It is important that dirt, leaves, mulch and other types of debris be kept well below the weep screed and the building’s walls. Allowing the weep screed to become covered or blocked can lead to moisture being trapped in the walls and deterioration.

The entire perimeter of the foundation should be checked several times a year to be sure that the weep screed is exposed to allow drainage and air circulation for drying.

:105 Weep Screeds

Filed under: :105 Weep Screeds — Tags: , , , , , , , — John Banta @ 12:01 am

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

1:5:10:105 EcoTip: The weep screed is a type of metal material that is typically installed at the bottom of a home’s stucco or some types of siding that allows any water that get past the outer finsh coat or material to drain away and exit. It is important that there be a minimum 4 inch clearance between the bottom of the weep screed and the soil or landscaped surface of the yard. 

If sidewalks, driveways, patios or other concrete or hard surfacees are installed next to the builidng there needs to be a minimum of 2 inches of clearance between the weep screed and that surface.
