This guide is limited to removing and replacing stucco and is not specific to the trim associated with window installation. Windows come in different types and styles and have different blinking methods. This document focuses on the work of plasterers and plasterers for rehabilitation.
Finishing options for repairs around windows depend on the degree of appearance or desire of the finish and should be discussed before starting work.

The following will help you make some decisions and options and help eliminate the confusion of everyone involved.
Evaluation:
Qualified Plastering Contractor in San Jose CA should conduct a comprehensive evaluation of the exterior plaster before making any decisions for the final scope of repairs. Buildings with elastomeric type paints will limit the options for repairs.
Stucco Removal:
The best way to get rid of stucco is to use a masonry saw and cut the stucco with a power saw. The blade should be set just below the full thickness of the stucco membrane, usually 3/4 inch. This protects the underlying weathering (WR) membrane from damage.
Masonry blades wear quickly, and the depth of the blades needs to be adjusted frequently. The plaster cut should be approximately 12 to 24 inches from the window sill. Vertical cuts may be further away from the window as they need to reach the closest framing member (Marion).
Once the saw cut is complete, a cold chisel can be inserted into the saw cut and used to break or break the last remaining uncut thickness of plaster. The stucco can then be removed from the wall with minimal damage to the underlying WR membrane. If the distance is large, it is recommended to cut the stucco into a square that is easy to handle.
In rare cases, the WR membrane can be glued to the back of the stucco. In these instances, it will be necessary to remove the stucco back to the point where it is not bonded to the WR membrane. Since the cut stucco edge is straight and smooth, it is recommended the edges be jagged and rough. This will produce a better key (bond) between the new patch and the existing stucco and minimize the chance of a separation crack.
Stucco Refurbishment
Before installing the WR diaphragm, the frame, casing, windows, and bezels must be installed/refurbished and inspected by a qualified person. There are several options, methods, and products for blinking windows.
