A sticky interior door is usually
attributable to either a door hinge becoming loose, or the door swelling due
to high moisture or humidity levels within the home. How to repair a sticky
interior door dramatically differs pending on which is the culprit
associated with your sticky interior door.
Tools Required for Repairing a Sticky
Interior Door
Screw Driver or Screw Gun
˝” or 3/8” dowel (12
inches in length)
Circular Saw
Long Straight Edge
Hand Plane
Chisel
Sandpaper
2 C-Clamps
4 wood shims
Carpenters Glue
Paint/Stain
The first thing to inspect when experiencing a
sticky interior door is the door hinges. Make sure all of the hinges are tightly
fastened to the door jamb and the door itself. Due to some basic laws of physics
and leverage, the upper most hinges along the door jamb are more likely to
become loose over time, so inspect these first. As the hinge becomes loose and
separates from the door jamb, the door leans out, if you will. Consequently the
far end of the door winds up rubbing up against the far side of door jamb, which
causes the stickiness.
Tighten Screws in Door Hinges
Use a screw driver or a screw gun to make sure
all of the screws are tightly secured to the door jamb.
If in the process of tightening the screws you
determine that one or more of the screws are stripped you can do one of two
things. First try to use longer screws in place of the original shorter ones. If
the longer screws do not securely fasten the hinge to the door jamb, you will
then need to go to Plan B.
Plan B involves the use of ˝” or 3/8” dowels.
When using dowels, first open the door widely and remove the screws from the
section of hinge. Swing the hinge away from the stripped out screw holes so that
the stripped out screw holes are visible.
Next, using a ˝” or 3/8” drill bit, drill out
the stripped out screw holes, approximately 1” in depth. Then, with carpenters
glue applied to approximately 1” of dowel, slide the dowel into the hole you
just drilled. Let the dowel and glue set up for 24 hours.
With the dowel now firmly setup and sanded flush
with the door jamb, position the hinge back over the door jamb and make a small
pilot-hole mark.
Again, slide the door hinge out of the way and
then drill a small pilot hole into the dowel, where you made the small
pilot-hole mark.
After the pilot-hole has been drilled refasten
the hinge using the original screws.
If the door hinges are all properly secured the
space between the door jamb and the door, on the hinge side, should be
approximately 1/8th of an inch the entire height of the door.

Trimming a Sticky Interior Door
If the interior door still sticks, then your
door may have swelled due to the absorption of moisture. If this is the case,
you will then need to remove the door and trim the opposite hinge side of the
door.
Before removing the door, attempt to close the
door and see where the door is touching the door jamb. Use a pencil and run a
mark along the length of the door where the door is touching the door jamb.
Next, remove the door from its hinges by pulling
out the hinge pins.
Lay the door on a set of horses or other flat
work area.
Using a long straight edge, run a straight line
along the length of the edge of the door such that it is consistent with the
marks you made earlier on the door.
Also, while still holding the straight edge,
score the line with a carpenter’s knife. This will help aid in preventing chips
in the door when cutting with your circular saw.
If the section of door material to be removed is
1/8th inch or less, use a hand plane to remove the offending wood.
If greater than 1/8th of an inch then
you will need to use your circular saw.
Using a couple of C clamps, and a few of shims
for protecting the door from the clamps, fasten your long straight edge to the
door so that it can be used as a fence for the circular saw. Position the long
straight edge board so that your saw will slide along side of it and cut on the
line that you previously made.
After cutting the door, lightly sand it.
Re-install the door onto its hinges, and check
to see if the door swings freely closed.
Once you have determined the interior door is no
longer sticking, remove the door again, and apply one coat of stain/paint to the
trimmed edge.
With the door reinstalled, your sticky interior
door is now a thing of the past.
