Hi folks,
My first post. Great site.
I have a door that leads down to the garage.
I have attached several pics, but as you can see, the floor is very uneven. In the closed position, there is a large gap. Lots of cold air (and probably some CO) seeps in quickly.
In the open position, the gap is almost non-existent.
I want to put some type of floor sweep on, but because of the variable gap, I am concerned the sweep will get stuck, or break, or the door may become tough to open/close.

What are some suggests for the best fix here? Currently using a towel.
Ideally would like to put some type of 'collapsible' door sweep on the garage side (pics 4, 5) for aesthetic reasons but cannot find anything suitable. Let me add, I've never installed a door sweep, so if the solution is obvious, please forgive.

Thank you in advance.

Normally I'd suggest just mounting a sweep at an angle to math the floor in the closed position. Or, trim the bottom of the door to have a consistent gap. But... you've got a floor like in those roadside "Mystry Hill" attractions. I'm not sure a traditional sweep will accommodate that much floor variation without trimming a lot off the bottom of the door to provide lots of room for the sweep to move and bend.

I think brush type sweeps handle wildly uneven floors better than a rubber strip type. Most home centers don't carry them so you might have to resort to looking online. You might also try one of those sewn draft stoppers that you slide in from the end of the door. They don't attach to the door and might be able to move up and down to follow the floor's undulations better.

 

With the floor being out of level, you likely will want a threshold bulb seal that is installed on the floor under the door... not "on" the door.

 

The right way would be to figure out under that area why the floors so out of level and fix that issue.
Second best would be to install an adjustable threshold and cut the door to fit.
With the door cut off you would have room to install a sweep on the bottom of the door and still not have it drag when the doors open.

 

Thank you for the replies,
It's an old victorian that has been raised for a garage. To fix the bent floor is $$$$. Interestingly, it's unnoticeable unless you put a golf ball on the floor and watch it roll or see this door closed.
I think I'll have to hire a pro to help fix this, it may be out of scope for my skills/tools.

 

I find it hard to believe that removing the existing threshold that has no weatherstrip, and replacing it with one that does... cutting something like this or this to length and screwing it down to the threshold under the door, is not within your capability.

It might require you cut the door slightly to get it to fit just right, (door bottom should have a slight bevel on it) but it is your best solution, IMO. Under $15 in parts. The door should be cut straight with the floor when in the closed position. Ignore everything else.

 

Last thing I'd want is a bulb seal on the threshold, I've replaced dozens of them.
On the bottom of the door there not going to keep popping out when they get stepped on.
