If doors in your home are squeaky, crooked, not closing properly, or scraping the frame or floor you may have a door that isn’t flush. Interior door hinge installation can over time become uneven due to frequent opening and closing. Left uncorrected the problem can cause damage. Fortunately it is quite easy to adjust hinges to make an interior door close flush. 


First you will need to determine if the door isn’t shutting all the way or if it won’t latch and stay closed. If the door is scraping the side of the door frame with the hinges you may hear cracking or feel it stop moving and this means it is is too close to the hinge side of the frame. If the door swings easily but doesn’t latch or hits the floor, top of frame, or latch side of frame it is too far from the hinge side of the frame. 


You’ll want to get another person to help you out with the next steps. Loosen the screws on the hinge plates that hold the hinges to the door frame. Have the person hold the door itself while you do this. Don’t be startled as the door will fall towards the floor away from the hinges. Do not loosen the screws on the door itself. 


Carefully line up the hinges so they are level and the lower hinges are below the higher hinges. You may consider using a ruler or measuring tape to ensure the hinges are in a straight line going down the  frame. If there was grinding against the hinge side of the frame you’ll want to move the hinges slightly forward towards the doorway. If the door was overextended and not latching or hitting the latch side of the doorway you’ll want to move the hinges slightly back.


Do not allow the other person to let go while the hinges are loose or allow the door to hang from one hinge. 


While having the door held in place make sure there is space below  (so it does not touch the carpet or floor) and there is a small space between the top of the door and the frame top. The spaces should be level and even across the door frame. 


Move the hinges carefully up or down a few millimeters if the door hits the top or the floor.  Once the door appears level and flush, tighten the screws on the hinge plates.


Gently open and close to ensure the door does not scrape, get stuck, or bang against the frame. If needed readjust the strike plate (where the door latches to stay closed) so it is flush inside it’s opening in the doorway. 


Repeat this process on any other doors in your home that need doorway adjustments to ensure your doors and frames remain in good condition over the years. Use a lubricant like WD-40 to keep the hinges loose and moving freely and to reduce squeaking.
