Key Elements of Internal Door Swelling in Winter
- Changes in humidity and temperature
- Proper installation and finishing
- Regular maintenance and adjustments
Introduction
As the cold winter months approach, many homeowners may notice that their internal doors start to swell, making them difficult to open and close. This is a common issue, even with high quality solid oak doors, due to the natural properties of wood. In this article, we will explore the reasons behind internal door swelling in winter and provide tips on how to prevent and address this problem.
The Science Behind Door Swelling
Wood is a hygroscopic material, meaning it absorbs and releases moisture from the surrounding environment. During the winter months, the humidity levels inside homes tend to increase due to factors such as central heating, reduced ventilation, and moisture from cooking and showering. As the wood absorbs this excess moisture, it expands, causing the door to swell.
- Temperature changes also play a role
- Expansion and contraction of wood fibres
- More noticeable in solid wood doors
The Importance of Proper Installation and Finishing
To minimise the risk of internal door swelling, it is crucial to ensure that the doors are installed correctly and finished properly. This includes:
- Allowing the doors to acclimatise to the home's environment before installation
- Ensuring that the doors are hung with an adequate gap around the edges
- Applying a high-quality finish, such hardwax oil, to protect the wood from moisture
Maintaining Internal Doors Throughout the Year
Regular maintenance is key to keeping internal doors in good condition and minimising the effects of seasonal swelling. Some tips include:
- Cleaning the doors regularly with a soft, dry cloth
- Avoiding excessive moisture near the doors, such as wet umbrellas or coats
- Ensuring adequate ventilation in the home to regulate humidity levels
- Checking and adjusting hinges and latches periodically
Addressing Swollen Doors
If your internal doors do swell during the winter months, there are several steps you can take to address the issue:
- Adjust the hinges: Loosening or tightening the hinges can help to realign the door and improve its fit within the frame.
- Plane the edges: In more severe cases, you may need to remove the door and carefully plane down the edges to create more clearance. This should be done gradually to avoid removing too much material.
- Use a dehumidifier: Placing a dehumidifier in the room can help to reduce the humidity levels and minimise further swelling.
Conclusion
Internal door swelling in winter is a common issue faced by many homeowners, including those with solid oak doors. By understanding the causes of this problem and taking steps to prevent and address it, you can ensure that your doors continue to function smoothly throughout the colder months. Remember to invest in proper installation, finishing, and maintenance, and don't hesitate to make adjustments as needed to keep your internal doors looking and performing their best.
Whether you have standard internal doors or more specialised options like bathroom doors, taking a proactive approach to door maintenance will help to ensure their longevity and functionality for years to come.
