If the door is sticking in several places, it could be swollen because of the humidity. This is likely to be the problem if your door sticks in summer, but is fine during the winter. If you have one, try running your air conditioner to get rid of the moisture in the air. Running a dehumidifier can help, too.
High humidity can also cause the lubrication in the door's hinge pins to degrade more rapidly and make the door more difficult to operate. Builtup dirt and grim around door and window frames can lead to sticking year-round, but higher humidity levels can cause it to clump together and become even more problematic.
Temperature: Heat can cause materials to expand. If the door or its frame is made of wood or metal, it may expand in the heat, causing additional friction and making it harder to open.
To prevent a wooden door from swelling due to humidity, treat it with a high-quality sealant or water-repellent finish. Products like polyurethane or marine varnish can provide a protective barrier. Additionally, ensure proper ventilation in the area and consider using a dehumidifier if necessary.
Humidity can cause excessive moisture and the heat can cause the door to warp. This warping can also occur around the lock, which can result in it becoming difficult to turn the key in the lock, or even cause the key to get stuck in it.

The biggest issue that can cause problems for doors, especially externally facing doors, is the presence of moisture. Temperature also can play a part – warmth can cause the wood to expand, meaning doors can become hard to close.
The sticking issue of your door can happen due to improperly installed or sagging door hinges. This happens when the screws of the hinges get loosened up and the door gets lopsided (this will commonly happen in homes with children who love to hang off the door handles). This is quite an easy problem to solve.
If the swelling is due to humidity, using a fan or dehumidifier can help reduce the moisture and make it easier to open. Will a swollen door go back to normal? Sometimes, yes! If the humidity drops, a swollen door might shrink back to its original size.
When you encounter a sticking door, there are a few simple solutions that often resolve minor issues quickly and easily. Checking screws, lubricating hinges, and readjusting the strike plate can help keep your doors from sticking.
A primary cause of swelling is when you have an oversized door. When the sun shines directly onto your door, it will expand, as this is a natural effect of direct or harsh sunlight. If this happens too often or if the heat is excessive, your door will become difficult to open and close as it should.
Moisture in the air causes wood to swell, and if you notice that your windows stick only during the sweltering summer months, then humidity is likely to blame. Windows also stick because the tracks that the sash slide up and down on get dirty and gunked-up with dust, dirt, pollen and debris.
Hot Weather Tips: Open vs.
During hot weather, keep interior doors open to help your air conditioner circulate cool air more effectively. Closed doors can trap heat in certain rooms, forcing your AC to work harder to maintain a consistent temperature throughout your home.
Identify the exact areas where the door sticks by marking with chalk or pencil. Use sandpaper for minor adjustments and a wood plane for larger corrections. Regularly maintain doors to prevent future sticking, including oiling hinges and checking for moisture damage.
Get some chalk and apply it to the edge of the door, and see where the chalk rubs off when you open and close it. After this, you have a range of options. If the door only causes problems in the summertime, it may be worth investing in a dehumidifier.
If you've noticed that you have sticking doors and windows in your home, it's likely a sign of larger, underlying foundation issues. Sticking doors and windows are some of the most common symptoms of foundation settlement, especially in the Southeast United States where humidity and rain cause many foundation issues.
Door Swelling
As we all know, excess moisture is wood's natural enemy and your wooden doors swell because it absorbs moisture that is present in the air. In the summer, it is not uncommon for doors to swell and start “sticking” as the humidity levels outside increase.
Basically to use a rasp, you simply place it on the surface you're wanting to reduce, and drag it across the wood. You need to apply pressure to the rasp so it digs into the wood as you slide it. There's really no way to mess this up.
Your door swells like that because it's not properly protected against moisture. This can be a problem with the door from the manufacturer, the door might have aged without being properly cared for, or if you did any work on your door without properly finishing it, that can cause a problem, too.
There are several reasons a door may stick in the doorframe, including loose hardware, a sagging frame, or seized hinges. Humidity is another common cause of sticking doors: The high moisture level in the air can seep into the wood, resulting in a swollen door that does not open or close properly.
Protect the door from extreme heat. If possible, advise trying to keep the composite door away from direct sunlight. Curtains, blinds, or awnings can be used to shade the door from the sun's rays and suggest fans or air conditioners to cool down the home and reduce the humidity level.
Tighten screws or bolts on the door frame and strike plate
The screws or bolts that secure the strike plate should be checked periodically to make sure they are tight. If they are loose, the strike plate will not be able to properly receive the bolt, and the door will not close securely.
