Can You Repair a Water-Damaged Wooden Door?

Wooden doors, while sturdy and classic, are susceptible to the relentless effects of water over time. Whether it’s due to a leaky roof, flooding, or even just prolonged exposure to moisture, water damage can wreak havoc on the appearance and structural integrity of your cherished entryway.

The beauty of wooden doors is undeniable, but they require regular cleaning and maintenance. Here, in South Carolina, hot and humid summers often give way to rainy and cold days in fall. Doors in the south often take a beating from weather.

We will explain how to repair a water-damaged door. However, even if the damage appears to be minor, we highly encourage readers to reach out to a professional to assess the full extent of the damage. Water can cause rotting on the inside of the door which in turn can lead to wood boring pests.

The front door of the home is an important aspect to your home’s curb appeal and is one of your first lines of defense to the elements and any unwanted intruders (even if that’s just Joe from down the street). It is important to the structural integrity of your home. Sometimes a door replacement is the more cost and time-efficient option versus a DIY repair.
