In the world of masonry, there is a distinct line between a standard functional fireplace and a masterpiece of thermal engineering. For homeowners in Ontario, particularly those residing in the historic pockets of the GTA or rural stone estates, the fireplace isn’t just a utility—it is the architectural soul of the home.

However, many traditional fireplaces suffer from a common flaw: they are inefficient, prone to smoking, and lose the vast majority of their heat up the chimney. This is where the Rumford Restoration by Bowman Masonry changes the narrative.

What is a Rumford Fireplace?

Developed in the late 18th century by Sir Benjamin Thompson (Count Rumford), the Rumford design revolutionized how we heat our homes. Unlike the deep, boxy fireboxes common in mid-century construction, a Rumford is tall, shallow, and features widely splayed “covings” (side walls).

The geometry is the magic. The shallow depth and angled sides act like a parabolic mirror, reflecting radiant heat directly into the room rather than letting it escape. Furthermore, the streamlined “throat” of a Rumford creates a laminar air flow that carries away smoke with surgical precision, even in homes that typically struggle with draft issues.

The Bowman Standard: Why Heritage Expertise Matters

Restoring or building a Rumford is not a task for a general “brick-and-block” contractor. It is a specialized craft that requires an intimate understanding of thermodynamics and historical masonry techniques. At Bowman Masonry, we don’t just “fix” chimneys; we restore the structural and thermal integrity of your home.

1. WETT Certified Precision

Safety is the non-negotiable foundation of our work. Every Rumford restoration we undertake is performed by WETT (Wood Energy Technology Transfer) certified technicians. This means your fireplace isn’t just beautiful—it meets the most stringent Ontario building and fire codes. We ensure that clearances to combustibles, flue sizing, and hearth extensions are handled with 100% compliance, providing peace of mind for your family and your insurance provider.

2. The Anatomy of a Restoration

A typical restoration begins with a forensic assessment of the existing masonry. We often find that older chimneys have suffered from decades of “thermal shock” and moisture ingress. Our process involves:

• Deep Cleaning & Inspection: Removing creosote and soot to reveal the true state of the masonry.

• Precision Refractory Work: Using high-heat firebricks and specialized refractory mortars that can withstand the intense radiant temperatures a Rumford produces.

• Custom Covings: Hand-carving the specific angles required to ensure the smoke-shelf and throat transition perfectly into the flue.

The Aesthetic Impact: A Design Centerpiece

Beyond the physics, a Rumford fireplace is a visual statement. Its tall, elegant opening offers a full view of the flame, reminiscent of the grand manors of the 1800s. Whether you prefer the rugged look of natural Ontario fieldstone or the clean, disciplined lines of pressed heritage brick, a Rumford provides a vertical canvas that draws the eye upward, making any room feel more expansive and sophisticated.

Sustainability and Efficiency

In an era where we are all conscious of our environmental footprint and rising energy costs, the Rumford stands as a surprisingly “green” historical technology. Because it relies on radiant heat—the same type of warmth you feel from the sun—it warms the objects and people in the room rather than just the air. This allows you to turn down the furnace and enjoy a carbon-neutral heat source that remains effective even during the coldest Ontario power outages.
