Just like with door frames and window sills, various penetrations such as piping, outlets, light fixtures, and other features on your stucco exterior can serve as entry points for water if they are not properly sealed. Without adequate sealing and water management systems in place, water intrusion can occur, leading to cracks and eventually stucco failure. Installing the correct water management systems, such as proper flashing, caulking, and sealants around penetrations, is crucial to protect your stucco from water damage. Ensuring that these features are sealed effectively helps maintain the integrity and longevity of your stucco exterior, preventing costly repairs and potential structural issues down the line.
