How to Seal a Drafty Sliding Door

  • Transcript

    LESLIE: Kathy in Florida, you’ve got The Money Pit. How can we help you today?

    KATHY: I have a problem – not I but my daughter has a problem with her sliding doors.


    KATHY: In winter, it’s awfully drafty. And on a previous show, you mentioned a product to put on that you can peel off in springtime very easily and that seals the doors and windows. But I did not get the name, so that’s why I’m calling back, if you remember that or if you can help me with this problem?

    LESLIE: Now, Kathy, it’s a very common product that we talk about often. DAP has one; it’s called Seal ‘N Peel Caulk. A lot of different manufacturers make one. But once she seals this door, it’s not something that you’re going to want to peel off and reapply. Is this a door that she uses often or could she call this doorway closed for the season?

    KATHY: No, she doesn’t use it in winter at all.

    TOM: OK. So then you could seal it off for the winter, as long as – and the thing that concerns me, though, in telling you this is while you can seal it off for the winter, you’re also sort of sealing it shut. So if this is an emergency exit out of the house, in the event of a fire or something like that, you might not want to do this. But the product is a weatherstripping caulk. It’s clear; it looks like silicone but it’s not. And you essentially caulk drafty windows or doors. And then in the spring, you peel it off and it doesn’t damage the underlying door.

    But like I said, because it’s a door, we don’t recommend that you seal it shut, because then you won’t be able to get out.

    LESLIE: And that’s a good option if the draft is coming in from around the door, like in the operable parts, the doorway itself, for lack of a better area to describe? If you feel that the draft is coming from the glass itself, there’s also those clear sheetings that you can attach, in addition to sealing off the other part, that you sort of blow-dry in place, that sort of seals off an additional layer if the draft is coming through the glass, as well. And a combination of those two things might work.

    TOM: It’s shrink film and it would attach to the outside frame of the door. It sort of has like a double-face tape attachment and then you heat it with a hair dryer and it shrinks and pulls really tight and taut. And of course, that would stop the drafts but in the event you had to get out in an emergency, you just break through and go on out.

    Alright, Kathy? So I hope that those are some good ideas that help you and your daughter out. Thanks so much for calling us at 888-MONEY-PIT.
