Understanding the Culprit: Moisture Invasion

Door swelling occurs when wood absorbs moisture from the surrounding air or direct exposure to rain or snow. This causes the fibers in the wood to expand, leading to a puffy, oversized door. The culprits of moisture invasion include faulty seals around the doorframe, gaps in the weatherstripping, or improper drainage on the exterior of your home.

Navigating the Swollen Door Maze

Method 1: Dehumidification Magic

Open all windows and doors in the room where the stubborn door resides. If the weather permits, create a cross-breeze. Place fans or dehumidifiers in the area to draw out excess moisture from the air. This might take several hours or even days, depending on the severity of the swelling.

Method 2: Directing the Sun’s Healing Rays

If the weather allows, reposition the swollen door so that it faces direct sunlight. Ultraviolet rays can draw out moisture and expedite the drying process. Remove the door if possible and place it flat in the sun. This method might not be suitable for doors made from softwoods like pine, as direct sunlight can warp the wood further.

Method 3: Enlist the Power of Silica Gel or Kitty Litter

Spread a generous amount of silica gel packets or kitty litter around the bottom of the swollen door. These moisture-absorbing wonders will soak up excess moisture, reducing swelling.

Method 4: Introducing Heat for Careful Expansion

Apply low heat from a hairdryer to the swollen area for a few minutes at a time. The heat will cause the trapped moisture to expand and escape, reducing swelling. Remember to keep the hairdryer moving and avoid overheating the wood.

Method 5: Removing the Lock for Relief

If the swelling around the doorknob or deadbolt is preventing the door from closing, consider removing the lock to ease the pressure. Once the door fits properly, you can reinstall the lock.

Preventing Future Swelling: A Proactive Approach

1. Sealing the Gaps

Inspect the weatherstripping around your exterior doors regularly. Replace worn-out or damaged strips to prevent moisture from seeping in.

2. Improving Drainage

Ensure that the area outside the door slopes away from the house to redirect rainwater from the foundation and door frame.

3. Paint and Stain for Protection

Apply a moisture-resistant paint or stain to the exterior of the door to prevent moisture absorption.
