Examples of Typical Improper Installation of Stucco and Manufactured Stone

“Kick-out” flashing not installed at the junction of the roof and wall Example of “kick-out” flashing-the purpose of this flashing is to stop water from flowing behind the stucco

When the stucco is installed without a space between the windows or trim there is a greater potential for cracking due to expansion/contraction Staining on stucco from water flowing past the end of the rain gutter

Staining on chimney due to water flowing past the end of a rain gutter-stucco should not be installed on the sloped portion of the chimney (Note that this chimney is a wood-framed enclosure and not a masonry chimney) Unsealed gaps between the stucco and the electric meter socket-proper flashing should be installed at the top of the meter socket

Sometimes the stucco is installed after the rain gutters. This creates a large opening for water to enter, especially when “kick-out” flashing is not installed The stucco extends down over the foundation wall and a weep screed was not installed at the bottom of the frame wall-note that the stucco has been repaired due to past problems

In addition to the lack of casing beads and sealant at the joints between the stucco and the window, this window also has integral J channels for use with vinyl siding-this is an improper window for this installation-some manufacturers provide filler strips for use with stucco installations The stucco has separated from the wall sheathing, apparently due to improper attachment of the wire lath

Casing beads were installed with spacing between the stucco and the window, but the gap was not sealed with caulk All penetrations through the walls should have flashing and should be sealed with caulk. This joint is not sealed-Note that flashing would typically not be visible at this or similar penetrations

This house had casing beads and sealant at the windows, but there were some gaps in the sealant. The house was less than one year old and significant leakage was occurring at some windows-this indicates that the windows flashing or weather resistive barrier were not properly installed-more caulk is not the correct solution to this problem The manufactured stone was installed without a space between the window trim and mortar, and the joints were not sealed with caulk-Note that when the window or trim does not project out from the face of the wall water penetration is more likely to occur at joints due to surface tension or wind driven rain

Gaps, unsealed joints, and a lack of flashing often result in water penetration. Often the weather resistive barrier also does not extend behind trim, which can allow water to enter behind the barrier This lower corner has been repaired in the past. The lack of casing beads and sealant at the joints between the stucco and doors indicates that the repair will probable not address problems with water penetration
