An improper door lock and strike installation can cause the door to not fully close properly. Similarly, a tweaked door or frame can cause excessive rubbing at the top or bottom of the door frame, causing the door to not fully close.
Check the tightness of the screws holding the door hinges. If they're nice and tight and a bit hard to unscrew, you might be able to solve the problem by simply screwing in screws that are about a half inch longer. That will go deeper into the door jamb and may hold the door better.
Adjust the closer tension: If the closer tension is too loose, the closer may not be able to close the door properly.

Common culprits include loose hinges, misalignment, friction, and even changes in humidity affecting wooden doors. Now, let's get hands-on and bring that door back to its obedient self. The first order of business is to inspect the hinges. Often, a door not closing properly is a hinge issue.
To try and fix a door latch stuck within a door, use a flathead screwdriver or a Philips head screwdriver to free the latch. Open the door and hold it in an open position with a door wedge. Next, place the screwdriver at the top of the latch and use a hammer to tap the latch and remove any obstructions gently.
DOOR HINGE ISSUES
One of the common reasons for closing door problems is the hinge. The screws that hold the hinge in place start to work loose and cause the door to sag or become tight. It results in the door not meeting the latch-side strike plate or scraping the door.
To fix a door that won't stay shut, check the hinges and tighten any loose screws, adjust the strike plate so the latch fits, use shims between the hinges and the frame, or replace the hinge pins with longer, thicker pins. If the problem persists, seek professional help.
If the door doesn't fully close, it's usually due to insufficient tension in the hinge mechanism. Increase the tension by rotating the adjustment pin or screw clockwise.
Start by opening the closer and removing the two side retaining pins. The spring can now be accessed through the central opening. Adjust the spring by carefully turning the screw located on the top of the device. Then, turn the screw counterclockwise to increase spring tension and clockwise to decrease it.
A storm door that does not fully close, and latches only after the entry door is closed indicates air is being trapped between the entry door and the storm door. If the trapped air is not allowed to escape as the storm door swings closed, then the storm door will not be able to close with enough force to latch.
If the closer doesn't close the door completely—or the door springs back slightly when you try to manually shut it—it's possible the arm has been installed incorrectly. You can locate most installation instructions on the door closer manufacturer's web site to assess if installation was done correctly.
There are many reasons why a door won't latch. Most of the time, it's because of old hinges causing a sagging door—or the door wasn't installed properly in the first place. For example, the door latch may not be perfectly aligned with the striker plate. Or there could be an issue with the door jambs.
Sagging Doors
You can find a pack of hinge screws for $5 to $20. Another option is to replace the hinges, which cost between $8 and $50, depending on the quality. The final tip before calling in professional help is to add shims—$5 to $10—behind the hinges.
Every 10-15 years. The type of hinges and the number of hinges installed are often chosen to cope with more weight than needed, resulting in a significant lifespan of between 10 and 15 years.
Squeaking or grinding noises
If you've noticed any of these three signs in your windows or doors, it's essential to address the issue promptly to avoid any further damage. Ignoring hinge problems can also lead to further issues down the line, such as compromised security in your home or reduced energy efficiency.
Try Tightening the Screws
If you suspect there's an issue with your door hinge, use a screwdriver to tighten any loose screws before making other changes. If the screws turn without tightening, you might need to use longer screws. This can be useful for fixing a sagging door, too.
Humidity is any wooden door's worst enemy. It causes swelling and warping of doors, frames, furniture, and even the wooden frames in your roof. If the humidity level's stable, then eventually things should balance out, but if it is constantly changing it presents its own problems.
Most of the time, when a door isn't functioning properly or is tilted to one side, the hinges are the problem. This could be the result of loose screws due to normal wear and tear, rust, or the consistent use of your doors. Slamming can cause this, too. If this is the case, you need to replace the faulty door hinges.
Misaligned door
Doors can become misaligned for a variety of reasons and this can cause the latch to rub against the strike plate attached to the door frame and not retract properly. You can fix this issue by changing the position of the strike plate, following the steps in our guide to fixing a door that won't latch.
Should I use WD40 to lubricate door locks? The simple answer is you should not use WD40 to lubricate locks. WD-40 is one of the solvent-based lubricants and does not contain any lubricant and over time can make your lock even stickier by gumming the lock up.
Sometimes a little dirt gets in the way and creates a sticky door. Next, try tightening all the hinges and screws. A loose screw can cause the door to sag and therefore, not line up with its frame properly. You can also try using WD-40 on them to see if that helps.
