What to Know About Replacing Exterior and Interior Doors

Replacing doors involves more than just choosing an attractive design. For exterior doors, consider factors like weather resistance, security features, and energy efficiency ratings. Interior doors require attention to room function, sound isolation, and matching existing architectural styles. The installation process differs between exterior and interior applications, with exterior doors typically requiring more precise fitting and weatherproofing.

Common Door Materials and Their Benefits

The most popular door materials include:

  • Solid wood: Offers classic beauty and durability but requires regular maintenance

  • Fiberglass: Provides excellent weather resistance and low maintenance

  • Steel: Delivers superior security and durability at a competitive price

  • Composite: Combines the look of wood with enhanced durability

  • Hollow core: Lightweight and affordable, ideal for interior applications

  • Solid core: Offers better sound isolation and premium feel for interior use

Impact on Energy Efficiency and Home Value

New doors, especially exterior ones, can significantly impact your home’s energy efficiency. Modern entry doors with proper weather stripping and insulation can reduce heating and cooling costs by preventing air leakage. Energy-efficient doors often qualify for tax credits and can increase home value. According to industry estimates, a quality front door replacement can recoup 65-91% of its cost in improved home value.
