Scope of window casing & trim installation & repair
Window casing and trim form the visible finish around an opening and should be distinguished from the frame or glazing itself. Share the profile, dimensions, and photographs of adjacent finishes. Ask about removal, matching material, fitting around uneven surfaces, filling, caulking, and paint, especially when water damage may extend behind the trim.
Identify casing, sill or surrounding trim
Photograph the window and the damaged or missing detail. State whether the work is inside, outside or both, and whether the aim is a new style or a match to existing trim. The visible casing is different from the window's operating frame and sash. If those components are damaged, include that information rather than assuming new trim resolves the entire opening.
Review the surface behind the finish
Ask what removal is needed and how the condition of the underlying wall or wood will be assessed. Moisture staining, softness or repeated cracking may need a separate cause investigation. New casing should not conceal unresolved decay or water entry. Show nearby coverings, outlets and access restrictions; removing shutters or curtains and protecting furnishings may need to be included.
Specify matching and decorative finishing
Agree on profile, material, joints and the treatment of gaps or visible ends. State whether filling, priming, painting or staining is included. Exact matching may depend on available products or custom fabrication rather than a simple stock replacement. Where older painted surfaces are disturbed, discuss applicable lead-safe requirements. A cosmetic trim repair is separate from repairing window hardware, glass or the building's weatherproofing details.

Project questions
How is window-casing repair different from repairing the window frame?
Casing is the visible surrounding trim. Photograph both it and the window so the provider can distinguish decorative fitting from damage to the structure holding the window or its glazing.
What should I ask if window trim shows signs of water damage?
Ask the provider to assess whether deterioration extends behind the trim. Agree on removal, matching, sealing and finishing while separating any wider repair from replacing the visible casing.
