Choosing Between Masonry and Prefab Fireplaces

A fireplace door is not only a functional addition to your home but also a stylish one. It enhances safety, improves energy efficiency, and adds a touch of elegance to your fireplace. When considering fireplace doors, it's essential to understand the types of fireplaces available and the installation and maintenance processes associated with them. This guide will help you make an informed decision.

Types of Fireplaces: Masonry vs. Prefab

1. Masonry Fireplaces: Masonry fireplaces are built from bricks, stones, or concrete blocks. They are typically found in older homes and are known for their traditional charm and durability. Here's what you need to know about them:

  • Appearance: Masonry fireplaces have a classic, rustic appearance that many homeowners find appealing.
  • Installation: Installing fireplace doors in masonry fireplaces requires custom measurements, as these fireplaces come in various sizes and designs. Doors are usually secured using masonry anchors and clamps.
  • Maintenance: Masonry fireplaces require regular maintenance to keep the chimney and flue system in good condition. Annual inspections, cleaning, and occasional repairs are necessary to ensure safe and efficient operation.
  • Benefits: Masonry fireplaces offer excellent heat retention, making them a cozy heating option. They also add value and aesthetic appeal to homes.

2. Prefab Fireplaces (Factory-Built Fireplaces): Prefab fireplaces, also known as factory-built fireplaces, are constructed off-site and assembled on location. They are a popular choice for newer homes and offer some distinct advantages:

  • Appearance: Prefab fireplaces come in a range of designs and finishes, allowing you to match your decor style.
  • Installation: Fireplace doors for prefab fireplaces are generally easier to install because these fireplaces have standardized dimensions. The doors are often secured with brackets or screws.
  • Maintenance: Prefab fireplaces usually have metal chimneys that require less maintenance than masonry chimneys. However, regular cleaning and inspections are still necessary to ensure safe operation.
  • Benefits: Prefab fireplaces are cost-effective, easier to install, and provide efficient heat output. They are also more versatile in terms of placement within a home.


1. Masonry Fireplace Door Installation:

  • Measure the opening accurately to ensure a proper fit.
  • Choose a door style that complements your fireplace's aesthetics.
  • Attach the door frame using masonry anchors and clamps.
  • Adjust the door for a snug fit, making sure it opens and closes smoothly.

2. Prefab Fireplace Door Installation:

  • Measure the fireplace opening to select the right-sized door.
  • Assemble the door frame according to the manufacturer's instructions.
  • Attach the door frame using brackets or screws provided.
  • Adjust the door to ensure proper alignment and functionality.


  • Clean the glass regularly using a fireplace glass cleaner to maintain visibility and appearance.
  • Inspect the door frame, hinges, and hardware for any signs of wear and tear. Replace damaged parts promptly.
  • Keep the area around the fireplace clear of debris and flammable materials.
  • Schedule annual inspections and cleanings by a professional chimney sweep.

Frequently Asked Questions:

  1. Can I install fireplace doors myself?
    Yes, if you have the necessary tools and skills. However, professional installation is recommended for safety and optimal performance.

  2. Can I keep the doors closed while the fire is burning?
    It's generally recommended to keep the doors open when a fire is burning to ensure proper airflow and prevent overheating of the glass. Some doors have screens that can be closed for added protection.

  3. Do fireplace doors increase energy efficiency?
    Yes, fireplace doors can help increase energy efficiency by preventing warm indoor air from escaping up the chimney when the fireplace is not in use.

  4. Can I use any type of glass cleaner on the doors?
    Use a glass cleaner specifically designed for fireplace glass to avoid damaging the glass surface.

  5. Do I need to remove the doors when cleaning the fireplace?
    Most fireplace doors can be easily removed for cleaning and maintenance, but it's essential to follow the manufacturer's instructions.

Choosing the right fireplace doors involves considering the type of fireplace you have, the installation process, and the maintenance requirements. Both masonry and prefab fireplace doors offer their own set of benefits, so select the one that aligns with your home's style, needs, and maintenance capabilities. If unsure, consulting with a fireplace professional can provide valuable guidance.
