A Guide by Evolution General Contracting

Interior doors are an important finishing detail, playing a major role in both the function and style of your home. The right doors can elevate your space and make it feel truly one of a kind.

Below is your complete guide to understanding your interior door options and making the right selections for your home. If you’re building, renovating, or simply looking to upgrade your space, this guide will help you navigate your options with confidence.

Interior Doors: What You Need to Know

Learn about the different parts of interior doors that affect the functionality, design, and cost. Here are the key decisions to make:

1. Door Height

Door height should complement your ceiling height.

• 6'8" Standard Height ($): Ideal for 8' or 9' ceilings.

• 7' Doors ($$): A great upgrade option for 9' ceilings.

• 8' Doors ($$$): A custom, luxury option for ceilings 10’ and higher.

2. Door Core (What’s Inside Matters)

The core is the inside of the door. Explore the different types:

• Hollow Core ($): 

  • The inside of the door is hollow

  • Lighter in weight

  • Sound does travel through the door

• Solid Core ($$): 

  • The inside of the door is filled with wood material, making it heavier

  • Reduces sound transmission

  • More durable

    
    

3. Finish Options

• Paint Grade: Pre-primed and ready to paint the color of your choice

• Stain Grade: Available in various wood species, depending on the grain you prefer. Ready for stain and polyurethane.

  
  

Your finish choice sets the tone, modern painted doors or rich stained wood for warmth and texture.

4. Panel Design

Panel style plays a major role in the overall aesthetic of your home.

• Raised Panel ($): The face of the panel is elevated. Flat Panel ($$): The face of the panel is recessed.

• Flat Panel ($$): The face of the panel is recessed.

  
  

Many homeowners choose flat panel designs because they complement shaker-style kitchen cabinetry beautifully.

5. Hinge Finish

Hinges attach the door slab to the frame. They are available in an array of

finishes and should match your door hardware.

Popular finishes include:

• Matte Black

• Brushed Nickel

• Satin Brass

• Chrome

• Oil-Rubbed Bronze

Consistency in finish creates a polished, cohesive look throughout your home.

6. Specialty Interior Doors

Specialty interior doors add character, flexibility, and architectural interest to your home while serving specific functional needs.

• French Doors: Glass panels allow light to flow between rooms while maintaining separation. Ideal for offices, dining rooms, and sitting areas.

• Barn Doors: These doors slide along an exposed track instead of swinging open, saving space and adding a strong design feature.

• Pocket Doors: Pocket doors slide inside the wall and disappear when open. Perfect for bathrooms, closets, and tight spaces.
