    LESLIE: Tanya in North Carolina is on the line with a door question. Tell us what’s going on. You’ve got some rot in the framework?

    TANYA: The threshold, at the bottom, is coming up; I guess it’s rotten under there. It’s got to be taken out. And then about a foot up, on each side of that frame, it’s rotted out. So do I have to take out the whole frame and put a new one in or can I just cut that off and replace that at the bottom?

    TOM: OK. So, Tanya, I think you’re talking about – when you say “frame,” I think you’re talking about the door sill and the door jamb. Is that correct?

    TANYA: Right.

    TOM: Not the frame of the wall?

    TANYA: Yeah, whatever the door fits in, yeah.

    TOM: OK. So that’s the door sill and the door jambs. And the best way to replace the door is to cut the entire door out, including the sill and the jambs all the way around, and then install a prehung exterior door.

    So down in North Carolina, for example, you can go to a Lowe’s and buy a Benchmark Door by Therma-Tru. Good quality, fiberglass door, all prehung. Pretty easy and straightforward to install that. And you won’t have to worry about it rotting out because it’s fiberglass.

    TANYA: Oh, OK.

    TOM: You don’t try to repair the jamb or the sill that are heavily rotted like that; you just tear them out. The easy way to do that, by the way, is to remove the trim off of all sides. And a contractor would use a reciprocating saw to basically cut the nails between the trim and the frame of the house. And that door will pop out in like five minutes.

    TANYA: OK.

    TOM: I mean it’s really easy to get it out just with the right tools.

    TANYA: OK. Thank you.

    TOM: You’re welcome. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
