Door Jamb Wood Rot? Here’s How to Repair It Like a Pro

To fix wood rot in a door jamb, start by cutting out the affected wood using a multi-tool or handsaw. Apply wood hardener to stabilize the area and fill the cavity with epoxy filler or a wood patch kit.

Sand and prime once dry, then paint to match your door trim. Don’t forget to seal the bottom edge of your door jamb to prevent future rot—Houston’s humid conditions make this step crucial.
