Heat and Character That Lasts Generations

Custom Fireplaces Built for Duluth Homes

If you live in Duluth, you understand how long and cold Minnesota winters can be, and how much difference a reliable heat source makes in your home. An indoor fireplace adds warmth to living rooms, basements, or bedrooms, and it becomes a focal point that defines how a room feels and functions. It also adds measurable value to your home, especially in a climate where heating costs and comfort are ongoing concerns.

JF Masonry LLC designs and installs custom masonry fireplaces and surrounds tailored to your home's layout and architectural style. We select materials for heat resistance and structural integrity, and we build each fireplace with attention to safety, ventilation, and long-term performance. Indoor fireplaces can be incorporated into new construction or added during remodeling projects, and each installation is crafted to enhance both function and interior aesthetics.

Construction That Prioritizes Safety and Efficiency

We begin by assessing your home's structure, available space, and chimney routing options in Duluth. A properly built fireplace requires a reinforced foundation, a firebox constructed with heat-resistant firebrick, and a chimney designed for efficient draft and smoke control. We handle all masonry work, coordinate with inspectors, and ensure the installation meets Minnesota building codes for clearances, ventilation, and fire safety.


After installation, you'll notice that the fireplace draws air smoothly so fires burn cleanly without filling the room with smoke, the surrounding masonry stays cool to the touch even during extended burns, and the structure remains stable without settling or cracking. The fireplace provides supplemental heat that reduces reliance on central heating, and it creates a visual and functional centerpiece in the room.


We can customize the surround using natural stone or brick depending on your interior design preferences. Mantels, hearth extensions, and built-in niches can be added to increase usability and storage. These fireplaces are built to last through decades of daily use during Duluth winters.

Practical Questions That Come Up During Planning

Homeowners typically want to know about placement, chimney requirements, and how the fireplace will affect heating before committing to installation.

What type of wood burns best in an indoor fireplace?
Seasoned hardwood like oak or maple burns longest and produces the most heat. Avoid burning softwoods like pine, which create more creosote buildup and require more frequent chimney cleaning.
How do you ensure the fireplace won't fill the room with smoke?
We design the firebox and chimney to create proper draft, which pulls smoke upward and out of the home. Correct sizing, damper placement, and chimney height all contribute to clean burning and ventilation.
Can a fireplace be added to an existing home?
Yes, we can install a fireplace during remodeling projects. This involves reinforcing the floor, routing a chimney through the roof, and ensuring proper clearances from walls and framing in Duluth homes.
How much heat does a masonry fireplace provide?
A well-built masonry fireplace can heat a large room and reduce heating costs during winter. It won't replace central heating, but it provides supplemental warmth and comfort during cold months.
What kind of maintenance does an indoor fireplace need?
You'll need to have the chimney inspected and cleaned annually to remove creosote buildup and check for blockages. Ash should be removed regularly, and the damper should be checked to ensure it opens and closes properly.
