Utah’s architectural landscape is a striking blend of rugged pioneer history and refined urban evolution. From the iconic red sandstone foundations in Southern Utah to the stately multi-wythe brick manors of Salt Lake City’s Avenues, our historic buildings are more than just shelter; they are the physical manifestation of our state’s heritage. However, the very environment that makes Utah beautiful—our high-desert sun, bitter mountain winters, and fluctuating humidity—poses a constant threat to these structures. Preserving historic masonry in Utah requires a specialized understanding of how local materials interact with an unforgiving climate, ensuring that the guardians of history remain standing for another century.
At Abstract Masonry, we believe restoration is a delicate balance of art and science. When dealing with structures built fifty, one hundred, or even one hundred and fifty years ago, modern “quick fixes” can often do more harm than good. To truly protect your investment, you must move beyond simple aesthetics and adopt a philosophy of preservation that respects the original craftsmanship and the geological realities of the Beehive State.
Understanding the Utah Climate Factor
Utah presents a triple threat to historic stone and brick: extreme temperature swings, low ambient humidity punctuated by heavy snowmelt, and the presence of soluble salts.
- The Freeze-Thaw Cycle: In many parts of Utah, it is common for temperatures to swing 40℉ or more in a single twenty-four-hour period. When moisture is trapped inside a brick or stone unit, it expands as it freezes, creating internal pressure that leads to “spalling”—the physical breaking away of the masonry face.
- The Salt Problem: Utah’s soil and the de-icing salts used on our roads often lead to efflorescence. This white, powdery substance isn’t just an eyesore; it’s a sign that sub-florescence (salt crystallization beneath the surface) is occurring, which can turn a solid brick into dust from the inside out.
- Ultraviolet Degradation: Our high-elevation sun beats down on southern-facing walls, causing thermal expansion. Historic masonry needs to be able to breathe and move slightly to accommodate this expansion without cracking.
Best Practices for Preserving Historic Masonry in Utah
To navigate these challenges, owners of historic properties should adhere to the following industry-standard best practices.
1. Prioritize Breathability with Lime Mortar
One of the most common—and catastrophic—mistakes in Utah restoration is the use of modern Portland cement on historic buildings. Before the mid-20th century, most buildings were constructed using lime-based mortars. Lime mortar is softer and more permeable than the masonry units themselves.
In the world of preservation, the mortar is intended to be the “sacrificial” element. It is supposed to absorb the stress of building movement and allow moisture to evaporate. If you repoint an old brick wall with rigid Portland cement, the moisture becomes trapped. During a typical Utah winter freeze, that trapped water has nowhere to go but through the face of the brick, causing it to shatter. Always ensure your restoration team uses a custom-matched lime putty or hydraulic lime mix that is softer than your historic brick or stone.
2. The Gentlest Means Possible for Cleaning
It is tempting to want to power wash decades of Utah dust and carbon staining off a building. However, high-pressure water blasting and abrasive sandblasting are the enemies of historic preservation. Sandblasting removes the hard-fired outer skin of a brick, exposing the soft, porous interior to rapid decay.
The National Park Service Preservation Briefs recommend using the gentlest means possible. This usually involves low-pressure water soaking (often under 300 psi) and soft-bristled brushes. For stubborn carbon crusts or metallic stains, professionals should use specialized chemical cleaners that are pH-balanced for the specific stone type (sandstone vs. limestone vs. granite).
3. Never Paint Historic Masonry
In recent years, the brick painting trend has swept through modern home design. While it may look clean for a season, it is a death sentence for historic masonry. Paint acts as a vapor barrier, sealing the brick pores. In Utah’s climate, moisture rises through the foundation via capillary action (wicking). When that moisture hits a layer of paint, it becomes trapped. The result is a cycle of rot, mold, and eventual structural failure of the masonry units. If you must change the look of your building, consider a breathable mineral stain or a traditional limewash, which allows for vapor exchange.
4. Manage Water Runoff
Water is the primary agent of decay. In Utah, this often comes in the form of snow piling up against foundations or ice dams in gutters that overflow onto the masonry.
- Check Gutters: Ensure downspouts direct water at least five to six feet away from the foundation.
- Grade the Soil: Ensure the ground slopes away from the building to prevent rising damp.
- Monitor Sprinklers: Many historic walls in Utah are damaged by poorly aimed irrigation systems that soak the masonry daily throughout the summer, leading to mineral staining and salt damage.
The Role of Professional Assessment in Preserving Historic Masonry
Preserving historic masonry in Utah is not a DIY weekend project. It requires a forensic approach. At Abstract Masonry, our process begins with an analysis of the existing materials. We look at the “bond” (how the bricks are laid), the composition of the original mortar, and the specific type of stone used.
For example, Utah’s “Nugget” sandstone and “Kyune” sandstone have different porosity levels. A cleaning agent that works on one might dissolve the binder in the other. By performing a professional assessment, we can identify whether a crack is “active” (moving) or “dormant,” allowing us to apply a repair that addresses the root cause rather than just masking the symptom.
Preserving Historic Masonry in Utah as an Investment
Beyond the sentimental value, proper restoration is a sound financial decision. Research from organizations like Preservation Utah has shown that properties in historic districts often maintain higher resale values and are more resilient during economic downturns. With the right materials and methods, your repairs will last 30 to 50 years. In contrast, improper “patch jobs” with hardware-store cement often fail within 5 to 10 years, usually taking the surrounding historic brick with them.
