  The Tradition Explained
First and foremost, it’s essential to understand that this practice isn’t universal but is common enough to have garnered attention. Traditionally, painters would leave the top edge of a door unpainted for a very practical reason — to protect the door from sticking. Before the advent of modern paints and finishes, which are designed to be less sticky and more durable, the paint on the top edge of a door could cause it to stick to the door frame, especially in humid conditions. By leaving this small strip unpainted, painters could help ensure that the door would open and close smoothly, without the annoyance of peeling paint or a door stuck shut.
A Nod to Historical Materials
Another reason for this practice harks back to the types of materials used in older homes. Historically, doors were made of solid wood, which is naturally hygroscopic, meaning it absorbs and releases moisture depending on the humidity levels in the environment. Painting all sides of a wooden door could potentially trap moisture within the wood, leading to swelling, warping, or rot over time. Leaving the top unpainted allowed for a degree of moisture exchange that could help prolong the life of the door.
Modern Times and Modern Practices 
In today’s era of home improvement and DIY projects, the question arises — is it still necessary to leave the tops of doors unpainted? With advancements in paint technology and the widespread use of materials less prone to moisture absorption than solid wood, such as composite or engineered wood, this practice has become less about necessity and more about tradition or personal preference.
However, some professional painters and seasoned DIYers continue to leave the tops of doors unpainted, either out of habit or as a nod to the craft’s historical practices. Others argue that with the right type of paint and proper application techniques, painting the entire door, including the top edge, offers a more finished look without the risk of sticking or moisture damage.
To Paint or Not to Paint?
For homeowners and DIY enthusiasts contemplating whether to paint the tops of doors, consider the following:
- Material: If you’re working with solid wood doors in an older home, leaving the top unpainted might provide some benefits in terms of moisture management.
- Paint Type: Modern paints designed for doors and trim work are formulated to minimize sticking and withstand the rigors of daily use. Using these products can reduce the practical need to leave the tops unpainted.
- Aesthetics vs. Tradition: Ultimately, whether to paint the top of a door may come down to a matter of aesthetics or adherence to tradition. Some may prefer the look of a completely painted door, while others appreciate the historical reasons behind leaving the top edge bare.
Conclusion
The practice of leaving the tops of doors unpainted is rooted in practical solutions to the challenges posed by older materials and finishes. While modern advancements have largely mitigated these concerns, the tradition persists among some painters and homeowners. Whether you choose to paint every inch of your doors or leave the top edge as a silent tribute to the craftsmen of yesteryear, it’s a personal decision that adds yet another layer to the rich tapestry of home improvement and DIY culture. So the next time you come across an unpainted door, take a moment to appreciate the history and tradition behind this seemingly small but significant detail. Instead of simply painting over it, you may just decide to leave it as is. After all, some secrets are better left uncovered. #UnveilingTheSecretsOfPaintingDoors
