Installation Instructions for Replacement of Aluminum Windows in Hard Coat Stucco 

Applications in arid climates. 

These instructions are designed for typical California hard coat stucco exterior applications. The 

installation must leave the existing aluminum window frame and weep system in place. 

These 

instructions are not to be used with any other construction method and rely on the integrity 

of the existing aluminum window frame and flashing system.

 Building designs, construction 

methods, building materials, and site conditions unique to your project may require an installation 

method different from these instructions and additional care. Determining the appropriate 

installation method is the responsibility of you, your architect, or construction professional. If you 

have questions, please contact your local Pella retailer.

REMEMBER TO USE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT.
