For most old, uneven door frames, pick an aluminum or vinyl screw-on door sweep first: it fastens to the door and uses flexible seals that adapt to uneven thresholds. If the gap is large or the floor very irregular, use a weighted door snake like the Gorilla Grip Door Draft Stopper. Slide-on sweeps and adhesive silicone strips can work for minor irregularities but have limits.

Best first choice for older doors you can drill into: aluminum/vinyl sweeps screw to the door and use flexible vinyl or brush seals that conform to uneven thresholds, though they require correct sizing and installation.
Best when gaps are large or floors are very uneven: a weighted, heavy-duty door snake stays in place and blocks drafts without installation, but it sits on the floor and may not seal tiny edge gaps tightly.
Good for minor unevenness when the door thickness matches: cup-style slide-on sweeps clip to the bottom edge and can flex for small irregularities, though they have limits with larger or irregular gaps.
Useful for small, irregular gaps as a peel-and-stick fix: flexible silicone conforms to slight irregularities but must be placed carefully and may not hold up for big gaps or heavy wear over time.
For an old door with an uneven frame, I’d skip the simple fabric “door snake” as the primary fix. The best setup is compressible weatherstripping on the sides/top + a flexible sweep at the bottom. This accommodates gaps that vary as the old frame has settled.
1. For the sides and top: M-D heavy-duty screw-on weatherstripping
$41.00
This is my pick if the frame is really crooked or the gaps vary noticeably. The screw-mounted design lets you position the seal rather than relying on a fixed adhesive strip. It's also much more durable than cheap foam tape.
2. For an uneven threshold: a brush-style or adjustable door sweep
This Old House specifically recommends a brush-style sweep for uneven floors, because the bristles conform to the contours instead of leaving gaps where the threshold isn't level.
If you want something simpler and adjustable, an aluminum/vinyl screw-on sweep is also a good choice; slotted mounting holes let you fine-tune its position.
$32.99
This is better when there's a large gap underneath and you don't want to modify the door. But it won't solve drafts coming through the sides or top.
Bottom line: For an old, uneven frame, I'd spend the money on proper screw-on compression weatherstripping around the jambs, then use a brush/adjustable sweep underneath. That's considerably more effective and permanent than a typical draft snake.
If you show me a photo of the closed door and the gaps around it, I can tell you exactly which type I'd use and what size to buy.
For an old, shifting, or uneven door frame (and the wavy, unlevel floors that usually accompany them), rigid aluminum-and-rubber sweeps or peel-and-stick strips will quickly catch, peel off, or leave wide gaps.
The best options for uneven setups adapt to changing gap heights as the door opens and closes:
Flexible Silicone Door Sweep with Integrated Brush : Unlike solid rubber flaps that stick or drag on high spots of an uneven floor, a high-density bristle-and-silicone sweep (such as the Esufeir Brush Door Sweep Go to product viewer dialog for this item.) flexes and deforms . The soft bristles ride smoothly over dips and bumps in old hardwood or uneven thresholds without creating a harsh dragging sound or binding up.
Expandable Open-Cell Foam Tape (for the sides and top of the frame) : For the uneven vertical gaps along the jambs, use an expandable impregnated foam tape like M-D Building Products Expandable Foam Weatherseal Go to product viewer dialog for this item. . Unlike standard rigid rubber or foam strips that are uniform in thickness, this slow-expansion foam decompresses to custom-fit odd, wavy, or tapered gaps along crooked old door frames.
Weighted Twin Draft Stopper / Door Snake (for interior/no-drill fixes) : If you don't want to attach hardware to a historic or warped door, a double-sided fabric draft stopper filled with dense foam or glass beads (like the Everlasting Comfort 2-Sided Draft Stopper Go to product viewer dialog for this item. ) is a great movable option . Because it's flexible and unattached to the floor, it rolls or slides easily over slight floor undulations (though it requires a threshold-free or flat-floor layout).

For an old door with an uneven frame/threshold, I’d skip the basic foam “draft snake.” The best solution depends on where the unevenness is:

An adjustable screw-on sweep with a flexible vinyl/rubber seal is what I’d choose for a permanent fix. You can raise/lower it and accommodate a threshold that slopes or varies in height. This Old House specifically recommends brush-style sweeps when the floor/threshold is uneven because the bristles conform to the contours.
A brush sweep is even more forgiving. The individual bristles flex independently, rather than needing a rubber strip to maintain continuous contact.
A sweep won't solve that. Use screw-on, compressible weatherstripping around the jamb. Tubular weatherstripping with slotted mounting holes is particularly useful on old doors because you can adjust its position to compensate for an irregular frame.
My recommendation for an old exterior door:
Adjustable sweep + adjustable/compressible weatherstripping around the sides and top. That's much more effective than a fabric draft stopper alone.
If you tell me roughly how big the gap is (e.g. ¼", ½", 1") and whether it's mainly at the bottom, sides, or top, I can point you to the exact type I'd buy.
For an old, shifting, or uneven door frame where gaps change size from top to bottom (or the floor slopes), a rigid, one-size-fits-all fix will usually fail or jam.
The best choices depend on whether you need to seal the bottom gap (where the floor/threshold is uneven) or the sides/top (where the old frame is out of plumb).
To help narrow down the ideal fix, let me know:
For an old, shifting, or uneven door frame (and the crooked floor or variable gaps that usually come with it), rigid or cheap peel-and-stick sweeps will quickly bind, peel off, or drag.
The best choices depend on whether the unevenness is at the bottom (the threshold/floor gap) or along the sides/top (the jamb).
To help narrow down the best fit, is the draft coming primarily from the bottom threshold , or the vertical sides/top of the old frame? Also, what kind of flooring does the door open over (wood, tile, carpet)?
For an old door with an uneven/crooked frame, I’d skip the typical fabric “door snake” unless you want a temporary fix. The best solution is usually adjustable/compressible weatherstripping, because it can accommodate gaps that change in size around the door.

M-D Platinum Expandable Foam Weatherseal is particularly good when the sides/top of the frame are uneven. The foam expands into irregular gaps rather than simply sitting at one thickness. It's about $24 for the 1½-inch version at the moment.
$15.37
I'd use a screw-on aluminum/vinyl sweep rather than adhesive foam. It's adjustable and the flexible vinyl seal can follow an uneven threshold better.
A screw-on compression weatherstrip is probably the best long-term approach:
$41.00
You can position it independently along the jamb so the seal compresses against the door without making the door difficult to close. That's a major advantage over peel-and-stick strips on an old, settled frame.
One important distinction: if you tell me whether the uneven gap is (1) around the sides/top, (2) underneath, or (3) both, and roughly how big the largest gap is (e.g. ¼", ½", 1"), I can tell you exactly which type I'd buy and how I'd install it.
For an old, uneven door frame and shifting floor gaps, a rigid or tightly stuck adhesive strip will often jam, peel off, or leave wide patches unsealed. The "best" choice depends on whether the gap is at the bottom of the door or along the sides of a warped frame.

To help narrow this down, could you tell me:
For an old, uneven door frame, the best solution depends on where the draft is coming from. In most cases, a combination of products works better than a single draft stopper.
If the draft is around the top and sides of the door, an expandable foam weatherstrip is usually the best choice because it compresses more where the gap is tight and expands where the gap is wider.
$23.93
If the draft is under the door and the threshold is uneven, an adjustable aluminum door sweep is more effective than a stick-on rubber strip because you can fine-tune its height to match the floor.
$15.37
If the gap under the door varies a lot (common in old houses), an adjustable threshold can make a dramatic difference by raising the sealing surface to meet the door.
$20.96
For a temporary or renter-friendly fix, a double-sided under-door draft stopper works well, especially if you don't want to drill into the door.

A few tips based on old-house experience:
If you can upload a photo of the closed door (inside and outside), or tell me:
I can recommend the most effective fix for your specific door.
For an old, crooked, or uneven door frame (and the sagging/slanted floorboards that usually accompany them), rigid or low-profile seals will leave gaps where the floor dips.
The best options for sealing an uneven gap depend on whether you want a temporary fix or a permanent hardware solution:
To help narrow down the ideal choice, tell me:
For an old, uneven door frame, the best solution is usually not a single draft stopper, but a combination that matches where the air is leaking.
An expandable foam weatherstrip is usually the most forgiving because it compresses differently along the frame, sealing uneven gaps better than standard foam tape.

This type of seal is designed specifically to accommodate irregular gaps that are common in older homes.
A screw-on aluminum door sweep with a flexible vinyl seal generally works better than stick-on strips because you can adjust its height to follow an uneven threshold.
$19.98
Door sweeps with flexible fins tend to seal uneven floors more effectively than rigid or brush-style sweeps.
A double-sided fabric draft stopper that slides under the door is a good temporary solution, especially if the floor itself is uneven.
