How Long Should An Interior Door Last

The lifespan of an interior door can vary depending on several factors such as material, quality of construction, usage frequency, and maintenance. Here are some general guidelines for how long different types of interior doors might last:

 

Solid Wood Doors: High-quality solid wood interior doors, when properly maintained, can last 50 years or more. They are durable and can withstand normal wear and tear. However, they are susceptible to warping, cracking, or rotting if exposed to moisture or extreme temperature changes. For example, in a well-insulated and climate-controlled home, a solid oak door could easily last several decades.

Engineered Wood Doors: These doors, which are made from a combination of wood products like plywood and particleboard, typically have a lifespan of 20 to 30 years. They are more resistant to warping than solid wood doors but may not have the same level of durability in the long term.

 

Hollow core doors are lightweight and inexpensive, but they also have a relatively shorter lifespan. They usually last around 10 to 15 years. They are prone to damage from impacts and may not hold up well to frequent use. For instance, in a high-traffic area of a home or office, a hollow core door may need to be replaced sooner due to dents and scratches.

 

Metal interior doors, such as those made of steel or aluminum, are highly durable and can last 30 to 50 years or more. They are resistant to fire, pests, and moisture. However, they can rust if not properly protected, and the finish may chip or peel over time. In a commercial or industrial setting, metal doors are often a popular choice due to their long lifespan and security features.

 

Fiberglass doors are known for their durability and low maintenance. They can last 20 to 40 years. They are resistant to warping, cracking, and fading. Fiberglass doors can mimic the look of wood, but with added benefits like better insulation and weather resistance.
