To stop the swelling, you can coat your door with weather-resistant paint, which can help create a barrier and seal out moisture. Depending on the type of paint used and where in your home it's located, this barrier may hold up for weeks or even months.
To fix a swollen wooden door frame, first identify and eliminate the moisture source causing the swelling. Sand down the swollen area until the door can close properly. If the swelling is severe, you may need to plane the affected section. After adjustments, seal and paint the wood to protect it from future moisture.
swelling is caused by humidity and temperature changes, which cause the wood to expand and contract. Over time, the door will adjust to the new conditions and return to its original shape. However, a hot air gun or hairdryer can be applied to the sides of the door to bring out moisture then can be sealed and re-hung.
How to use WD40 to repair a swollen door? Remove the pin from the door hinge with a screwdriver and a hammer. Spray WD40 inside the hinge. Clean out any drips. Spray the pin itself. Put the pin back in the hinge and hammer it down. Adjust the spring. If too strong, adjust back to previous position.

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.

Don't seal warped doors, this will not allow the imbalance to correct itself. In most cases a warped door will straighten out after it has acclimated to its surroundings. We recommend the door be allowed to hang through at least a heating and cooling season to allow it to straighten out.
Heat Causes Expansion
Doors made from wood absorb moisture from the air. Due to the absorption, your front door swells and expands, which can make it hard to open and close the door.
If your door is rubbing against the frame, grab some sandpaper and smooth out the swollen spots. Take it slow—sand a little at a time and keep testing the door to make sure you don't overdo it. Focus on the areas causing the sticking, and stop once the door opens and closes easily.
Remove the blisters by scraping or sanding down to the bare surface. Prime all bare areas with a high-quality primer. Repaint the surface with a high-quality paint in the desired finish.
If your door latch and handle work efficiently, try lining the surface between your door and door frame with a small amount all-purpose lubricant. Use either a squirting bottle or a narrow spatula to apply lubricant to the closed door.
Apply wood glue to the concave side of the door (you only need to apply the glue to the areas affected by the warp). Clamp the door to the surface it is on - these clamps need to be along the warp to apply even pressure. Tighten your clamps until the door straightens out.
The swelling is caused by humidity and temperature changes, which cause the wood to expand and contract. Over time, the door will adjust to the new conditions and return to its original shape.
Timber tends to swell more with moisture (and some composite doors do contain timber), and humid weather can bring a double whammy of heat and ambient moisture to swell your doors with! Swelling in heat/humidity isn't anything you need to be worried about, as this is a natural process that affects these materials.
Why Is My Door Sticking? If you're struggling with a sticking door, you could be facing one of a few common door problems. Improper installation, sagging or broken door hinges, wear and tear, or friction within the strike plate can all cause a door to stick.
The exact drying time will vary depending on humidity, temperature, and the type of paint used. As a general rule, wait at least two to three hours before gently closing the door.
Cover the swollen furniture with a wet rag and set your iron to a low-temperature setting. Hold the iron down on the rag for a few seconds. Be careful not to hold the iron in the same place for too long as this could further damage the wood.
- The swelling of wooden doors is caused by the process of imbibition. Imbibition is the absorption of water by solid particles of a substance without forming a solution. The two essential things for imbibition are absorbent (wooden frame) and liquid imbibed (water).
Swelling increases until the fiber saturation point has been reached. Water added beyond this point remains as free water in the lumen and does not cause further swelling. This process is reversible and accounts for the dimensional changes that occur when wood comes into contact with moisture (Stamm 1964).
