The back door in my house is catching on the aluminum door sill. It's
starting to pull the steel skin on the door. I'd like to fix this before it
gets any worse, but I'm not sure how I should go about it.
The door opens outwards, and is fitted into a double door opening. The other
half of the opening is a door sized swing out window.
I'm guessing that the door wasn't installed properly originally and the
framing isn't square.
So, short of pulling the door right out and starting over, what can I do?
Is it the knob side scraping? You could try putting a dense cardboard
shim between the bottom hinge and jamb to see if the other side moves
up a tad.
"If things get any worse, I'll have to ask you to stop helping me."
They're probably right, but get your cheek down on the floor and see
exactly what is grabbing. I tried using logic to deduce what the
problem was with my door and it didn't work.
Maybe you have one particular part of the door which has gotten bent
down and it is doing the grabbing. You can only tell by looking.
My problem wasn't like his and wasn't a level issue. It didn't shut
well because of a twisted aluminum strip under the door. I was able
to bend it straight with a prybar of some sort under the door.
Even if his door is not level, he should still look under the door.
Maybe there is some other added or bigger problem.
I agree, there is no substitute for a good look at the thing. Chances
are it is a problem on the hinge side, a hinge has gotten loose or
something. On the other end of the scale it may be that the house has
settled, so the door frame is no longer square. But you won't know
until you look it over. We had a similar problem recently, the old
aluminum storm door in back was not closing properly. Once I took a
good look at it I saw that of the 5 hinges, 4 were broken! It was
hanging on by the last (topmost) hinge only, plus the closer. No
wonder it was closing funny. Replaced it that weekend. -- H
If the hinges are tight against the jamb, then can also be a problem with
the hinge side of the jamb itself. Sometimes these are installed with nails
which come loose, shims which slip down, and too short screws which don't
Then with some "weekend carpenter" jobs, the framing the hinge side jamb is
attached to... is "loose" or not well attached.
If hinges are tight against the jamb, might need to pull off the molding
around the door and see what is going on between the jamb and the wall
The screws which come with hinges are *never* long enough in my opinion. If
the top hinge is loose, take the hinge off and take to hardware store. Get
really long wood screws which lay flush with the hinge. This can solve a lot
of problems and make the hinge stay put. Also long screws can extend past
the jamb into the framing behind and snug it up a little.
Get extra screws. If you start to screw in one of these long screws and it
begins to strip, stop, unscrew it and screw in another. Might need to drill
a little hole so the screw will go in all the way without stripping.
The above is usually the problem, but sometimes can be the metal threshold.
The wood below the threshold can get wet and swell up or there can be
problems with the floor under that.
In some cases "nothing" is square, the floor under the threshold is not
level, the framing around the door is not square, etc. In these cases, it is
nice to have an all wood door so you can saw a little off here or there to
make things fit. But this is not always possible with a door which is part
wood and metal. If you saw off any of the door, the metal will come loose!
(I suppose you could screw the metal to the door, but that would not look
