DIY vs. Call a Pro
Replacing a pre-hung interior door is a common DIY project. Remove the old door and frame, set the new pre-hung unit in the opening, shim for plumb and level, nail in place, and add trim. Exterior doors require more weathersealing knowledge.
Call a professional when:
Hire a professional for exterior entry doors (proper weathersealing is critical), sliding patio doors, structural modifications to door openings, or if the rough opening needs resizing.
