Reasons For Replacing Doors 

There are  reasons why you may want to replace your doors: 

  1. They’re outdated or damaged, which poses a security threat or reduces energy efficiency. 
  2. You’re looking for a new style that improves the aesthetic of your home.


Replacing damaged doors is necessary, but replacing your doors for design purposes is also a worthwhile investment. Ornately carved doors and frameless sliding glass systems are both modern and chic options for homeowners looking to enhance both the exterior and interior of a home. Glass doors also offer energy-saving features such as improved insulation low-E window glass that decreases heating and cooling costs.

Assessing your current doors

Many homeowners replace their doors simply for aesthetic reasons, but damage and security threats are also important reasons to conduct a door replacement. To find out if your current doors require replacement, check for the following signs: 

  • Difficulty opening and closing 
  • Damaged or warped frame 
  • Cracks that create water and air leakage 


Damage is usually easy to detect in most doors. Even metal doors, which tend to be longer-lasting, can rust and corrode over time. Any type of damage makes a door less attractive and less secure, so it’s a worthwhile investment to replace it.

Types of Doors & Popular Materials 

Once you’ve decided that it’s time to replace your current door, it’s time to choose what type of door you want to install to replace it. There are endless options for door replacements, but these are 3 of our favorite varieties and materials: 



Wood is undoubtedly the most popular traditional option for interior and exterior doors. Sturdy and elegant, wooden door replacements are easy to customize with accents like glass panels. However, wood is vulnerable to weather and absorbs moisture, which can cause warping and cracking over time. Most homeowners investing in a door replacement choose more durable materials to give them a bang for their buck.

Glass doors are becoming an increasingly popular choice for homeowners looking to increase their home’s curb appeal, property value, and functionality. Frameless sliding glass doors offer ample natural light, customizable openings, and seamless transitions from indoor to outdoor spaces. Glass doors can either be top-hung or bottom-hung based on your preference and security needs.

If security is a top priority for your door replacement, steel might be a good choice for you. Steel doors are strong, durable, and don’t absorb moisture, so they’ll hold up for years. These doors are pre-hung in insulated frames made of wood or steel with a foam core, and they are finished with a durable powder coat or baked-on enamel.
