Window casing and trim finish the opening around the window; they are not the same thing as the structural or operating frame. That distinction matters when a project starts with cracked, loose or missing wood around an otherwise usable window.
NY-GoodHome provides window casing and trim work in Brooklyn and New York City. Call (223) 226-1828 with photos of the entire opening and close views of the trim profile.
Casing vs Window Frame
Casing is the visible finish around the opening. The window frame or jamb is part of the window assembly itself. If the operating frame is rotted, cracked or affecting how the sash works, Window Frame Repair is the more accurate page.
Matching Existing Trim
Replacement sections need to relate to existing width, thickness and profile. Exact historic matches are not guaranteed. If the room has unusual millwork, identify the profile before the damaged piece is removed.
Moisture and Rot
Trim that has rotted around a window may be responding to water from the exterior, frame or seal. Installing fresh casing without addressing an active moisture source can repeat the failure.
Wood Rot Repair is the right path when decay is the main issue.
