Sometimes you will find that some of the interior doors are thrown off balance due to wear and tear over the years. The following are some hints for what to do to rectify this problem and make your interior doors plumb.

Step 1 - Check the Door

If you find that a door closes on its own, it typically means that the house has settled and the door is not hanging level from the frame.

Step 2 - Place a Wedge in the Door

A quick fix would be to wedge something between the lower hinge and the frame of the door. If you don't want to remove the door, you can loosen the screws to the frame and slide a piece of heavy paper or cardboard under the hinge. Then tighten the screws. If it still is not balanced, you can either make the cardboard thicker or thinner, depending on which solves the problem.

Step 3 - Remove the Door

Another way would be to remove the door completely, take the out of the hinge and bend the pin slightly with a hammer, then slip the pin back into the hinges and re hang the door. Bolts on doors can work out of the hinge, which will make the door stick. To repair this you can take a rubber mallet and tap the bolt in place. Take a look at the other hinges and if necessary, hammer those bolts as well. If the hinges are worn, replace them with new ones.

Step 4 - Re-Align the Track

If a door has come off it's track, take the edge of the top of the door and raise it a little above the track glide. Rest the door on the glide and lift the door up over the bottom glide track. Then sit the wheels of the bottom of the door back onto the track. Snap the door back into place.

Step 5 - Adjust the Screws

Even vinyl sliding glass doors will come off balance. They can be rebalanced by adjusting the screws for the height of the wheel. There are screws at the end or middle of the indoor bottom rail. These can be turned either clockwise or counterclockwise to raise or lower the wheel, which will realign the door with the door jamb.


When re-plumbing a door, if the door is seriously off-balance, you will always need to remove the door completely to adjust the hinges and add the shims where necessary.

Add a 3-4 inch screw to the top hinge to prevent a door from sagging.
