I have a three-season sun porch off the back of the house. When the dog was younger and out there, he just chewed the heck out of the door frame. There's a framing piece, perpendicular to the face of the door, that has a gap where weatherstripping slots in, and that's been destroyed/chewed off to right about the door handle. From inside, you can see daylight between the door and frame. In winter, there's just cold air rushing in, and of course it looks terrible.
Is there an option besides completely replacing the door and frame with a new pre-hung door?
It's more a problem of stock/availability during Covid than cost, I just can't seem to find the same type of door in stock or shipped before spring. I've had to repair chewed interior door frames, but this seems like a bigger problem, or I'm just not seeing how to go about it.
