My Inside Doors Swell; Why Is That?

Swelling in a wooden door is a common issue faced by many homeowners, including those with solid oak doors. The main reason for this swelling is higher relative humidity during winter months, which can cause the wood to expand and contract. Some door materials are prone to swelling during humid seasons, and understanding the causes and taking appropriate preventive measures can help reduce this problem.

Humidity levels are particularly susceptible to internal doors, as they absorb moisture, causing them to expand and swell. Door sweeps are a cost-effective way to prevent drafts and weather elements from damaging your doors by filling the gap between the bottom of the door and its frame. To stop doors swelling in winter, DIYers can do eight things:

1. Keep the door open and dry.
2. Use a drier to remove moisture from the wood, which can cause it to swell slightly.
3. Keep heat sources at least 36 inches away from the door.
4. If the door is stuck in several places, it could be swollen due to the combination of temperature and humidity changes inside and outside the home.
5. If there is a heat source close to the door, keep it at least 36 inches away from the door.
6. If the door is sticking in several places, it could be swollen due to the humidity.\n8

In conclusion, swollen doors in winter are caused by moisture damage, temperature changes, and the presence of heat sources. By understanding the causes and taking appropriate preventive measures, homeowners can help prevent and repair these issues.

How to fix a swollen interior door?

Swelling of doors can be addressed by air drying, sanding, sealing, painting, or replacing the door. Doors made of solid wood naturally expand and contract due to temperature changes. Common reasons for swelling include age and usage, humidity, low-quality raw materials, insufficient polish, misalignment of door frames during installation, and hanging or loose hinges. To fix minor swelling, use sandpaper or sander to absorb moisture from the door, seal, paint, or polish the surface, or replace the door. It’s essential to be aware of these potential issues to ensure safety and privacy in your home.

Will a swollen door go back to normal?

Over time, a swollen door will undergo a process of adaptation to its new conditions, returning to its original shape. In order to repair a door that has become swollen, it is first necessary to conduct an inspection to ascertain whether there are any visible signs of damage, such as cracks or splits in the wood. This is to ensure that the door will return to its original shape once the swelling has subsided.

How do I stop my internal doors from expanding?

Daily door inspections can prevent swelling by ensuring no gaps in vulnerable areas and adding paint or primer to cracks. Paint around door edges can also cause stickiness. Moisture is the most common cause, but other factors like frequent opening and closing, loose hinges and screws, and misaligned frames can also contribute. To fix these issues, contact a local expert. If your door is old and beyond repair, replace it with a reliable contractor, such as A Cut Above Outsides, who specializes in screens, patio doors, and siding replacements.

Why have my internal doors swollen?

Wooden doors swell due to their ability to absorb moisture from the air, which can be a problem in homes with high humidity levels. Wooden doors are more prone to sticking than those made from uPVC due to their natural reaction to temperature and humidity changes. While installing a dehumidifier can help reduce humidity, homes are designed to be lived in, and humidity is always in flux. This can lead to swelling, warping, or incorrect door hanging due to swollen or warped wood, shifted frames, or damaged hinges.

Humidity is the worst enemy of wooden doors, causing swelling and warping in doors, frames, furniture, and even roof frames. Maintaining a stable humidity level can help balance out issues, but constantly changing humidity can present new problems.

How to stop door swelling in winter?

To prevent doors from swelling in winter, keep humidity low, avoid cold drafts, use a door sweep, caulk gaps, install weatherstripping, keep doors clean and waxed, and inspect them regularly. The main cause of door swelling is the drastic temperature change, as the air holds less moisture in cold weather, causing the wood to absorb moisture and swell. To prevent this, follow these 8 ways:

1. Keep doors clean and waxed;
2. Install weatherstripping;
3. Regularly inspect doors for damage and make necessary repairs.

How to fix a swollen door in winter?

To fix a swollen door in winter, gently sand down the affected areas and apply a sealant or paint to protect the wood from further moisture damage. Address leaks or humidity issues to prevent future swelling. Regular maintenance can help mitigate this issue during colder months. A swollen door may return to normal size when humidity levels decrease or temperature changes, but extensive swelling from moisture or heat can cause permanent warping.

To prevent swelling, maintain stable indoor humidity levels, ensure proper ventilation, use a dehumidifier if needed, and seal the wood with paint or varnish. Regularly check weather stripping for gaps and repair as needed to minimize moisture exposure and swelling.

How to stop doors from swelling in summer?

Investing in dehumidifiers and air conditioning can help control the climate in your home. Dehumidifiers reduce air moisture, making it harder for timber to absorb water and swell. Air conditioning also helps by lowering indoor humidity levels, especially during sticky summer months. Place the dehumidifier in the same room as the affected door for best results. Regularly check your dehumidifier and air conditioning units, cleaning filters and emptying water reservoirs as needed. This will help prevent moisture saturation in the air and prevent moisture-related issues.

Does humidity cause doors to stick?

Humidity can cause doors to stick due to various factors. Wood expands when moisture is absorbed, making the door swell and difficult to open. Metal components like hinges and screws can rust in humid conditions, making the door harder to open. Dirt and debris build up on the door’s surface, making it harder to open. Therefore, humidity plays a crucial role in determining the effectiveness of doors.

Will swollen wood go back to normal?

Humid air causes wood to absorb more moisture, causing swelling. Dry air releases moisture, causing wood fibers to shrink. Moisture enters floorboards through the subfloor, causing the bottom to swell and edges to curve upward. Cupping can occur even on flawlessly installed wood floors, depending on building conditions and environment. Common situations causing cupping can be addressed and reversed.

Why do wooden doors expand?

Imbibition is a distinctive form of diffusion whereby water is drawn into either dead or living cells as a consequence of their affinity for water. During periods of precipitation, the cellular components of wooden doors that have undergone decay absorb water, resulting in an increase in volume and swelling.

How to flatten swollen wood?

Mayonnaise is an effective method for removing white water marks from wood furniture. Rub a tablespoon of mayo onto the damaged area, leave it overnight, and then remove it with warm water. Use equal parts olive oil and vinegar to wipe the affected area in the same direction as the wood grain. If the water damage is damp, use a cloth on top and rub the iron on a low setting with no steam. Use non-gel and non-whitening toothpaste to buff the affected area.

If the water mark is dark, it may require total surface refinishing, which can be daunting, especially if the piece is valuable or a family heirloom. If you’re struggling or don’t have time, consider contacting a specialized wood furniture store like Woodcraft. They offer refinishing services based on years of expertise to bring your furniture back to life.
