Answers: How do I fill a tapered gap between a door casing and door jamb?

• tapered door casing extensions
• fixing out of square door frames
• caulking door trim
• using a belt sander for trim

What it concludes

• Pre-assembling and installing a tapered extension piece allows you to cleanly fill uneven gaps between door casings and out-of-square door jambs.
• Using a putty knife rather than your finger to smooth caulk prevents pulling material out of the crack.
• Applying a slightly rounded edge to the trim helps it accept caulk better and reduces splitting over time.
