The main types of masonry work in Chicago are brick masonry, stone masonry, concrete block (CMU), and stucco systems — built either as load-bearing solid masonry or as a thinner veneer attached to a structural frame behind it.
At Fortune Restoration, we’ve worked on just about every type of masonry you’ll find in Chicagoland — soft historic brick on Frank Lloyd Wright homes in Oak Park, Indiana limestone facades on Loop commercial buildings, terra cotta ornament on pre-Depression apartment buildings, and concrete block construction across the city’s industrial corridors. Each material has its own personality. They age differently, they fail differently, and they need different repairs.
This guide walks through the main types of masonry construction we see across Chicago, what sets them apart, and how to think about which fits a particular project — whether you’re planning new construction or restoring something that’s been standing for a hundred years.

Solid Masonry vs. Veneer Masonry
Solid masonry uses brick or stone as the structural wall itself. Veneer masonry is a thinner masonry skin attached to a wood- or steel-framed wall behind it that does the actual structural work.
Most Chicago two-flats, three-flats, courtyard apartment buildings, and pre-WWII single-family homes were built as solid masonry — typically two or three wythes (layers) of brick that carry the building’s load. Walk through Lincoln Park, Bucktown, Pilsen, or Wicker Park, and most of what you’re looking at is solid masonry construction.
After about 1950, veneer masonry became standard for new residential and a lot of commercial work. The wall is framed in wood or steel, sheathed and waterproofed, and a single layer of brick or stone is built outside that — anchored back to the structure with metal ties.
The distinction matters when something fails. On solid masonry, mortar deterioration and brick spalling are structural concerns — the masonry is the wall. On veneer, the framed wall behind the masonry is doing the structural work, but failed masonry still allows water into the wall assembly and damages framing, insulation, and interior finishes. Either way, the repair needs to happen. Learn more about how we approach masonry repair on existing buildings.
Brick Masonry
Brick is the most common masonry material in Chicago because it’s durable, fire-resistant, and weathers well in the city’s freeze-thaw climate when paired with compatible mortar and reasonable maintenance.
Most of Chicago’s residential housing stock — bungalows, two-flats, greystones, and the courtyard apartment buildings that define so many neighborhoods — uses brick masonry. The bricks themselves are remarkably long-lived. Quality fired clay brick can last 100+ years with proper care. The mortar joints, on the other hand, are the sacrificial element — they’re designed to fail first to protect the brick.
That’s where tuckpointing comes in. Mortar joints in Chicago typically need attention every 25 to 30 years, sometimes sooner on heavily exposed elevations. Failed mortar lets water into the wall, where freeze-thaw cycling does the real damage.
Historic Chicago brick — anything built before 1930 or so — was set with soft lime mortar. Using modern Portland cement mortar to repair it is a common and expensive mistake we see all the time. Hard modern mortar transfers stress to the brick instead of yielding under it, leading to spalled brick faces and accelerated damage. The Brick Industry Association and the National Park Service preservation brief on repointing both stress mortar compatibility on historic work — it isn’t optional.
When individual brick units are spalled, cracked, or missing, brick replacement is the right call. The challenge is matching color, size, and texture so the repair blends with the surrounding wall.
Stone Masonry — Dressed and Undressed
Stone masonry uses natural stone (limestone, granite, sandstone) either as cut, uniform “dressed” blocks or as irregular “undressed” rubble laid in a more natural, varied pattern.
Chicago has remarkable stone masonry across its commercial and institutional building stock — Loop office buildings, university campuses, Gold Coast mansions, and churches throughout the city. Indiana limestone shows up everywhere because it was quarried within rail distance and shipped easily.
Dressed stone is cut and finished to specific dimensions, producing the clean coursed look you see on most institutional and high-end commercial buildings. Undressed (or “rubble”) stone is laid in irregular sizes for a more rustic appearance — common on retaining walls, foundation walls, and certain historic farmhouse-style residential work.
Stone weathers more slowly than brick but it isn’t invulnerable. Limestone in particular is calcareous — it dissolves slowly under acidic rain and urban pollution. We see this clearly on older buildings around the Loop where decades of atmospheric deposits have visibly eroded carved stone details. Restoration on these buildings is delicate work, especially on historic landmarks.
Concrete Block Masonry (CMU)
Concrete masonry units (CMU) are large concrete blocks — faster to lay and more affordable than brick or stone, which is why they dominate utility, foundation, and commercial backup-wall construction.
Concrete block has a place in almost every modern construction site. Foundation walls, garage walls, school and warehouse construction, factories, and most commercial backup walls behind brick or stone veneer all use CMU.
The tradeoff is appearance. Plain CMU isn’t pretty, which is why most exposed CMU is either painted, parged with stucco, or hidden behind a brick or stone veneer. There are decorative options — split-face block, scored block, glazed block — that produce a more finished look, but they cost more and are less common.
CMU is durable and structurally efficient. It does have its own deterioration patterns: joint failures, freeze-thaw spalling on exterior exposures, and corrosion of embedded reinforcing steel. The International Masonry Institute publishes good technical resources on CMU construction and maintenance for anyone who wants to dig deeper.
Stucco and Other Specialty Masonry Systems
Stucco is a cement-based plaster applied over masonry or wood-framed walls. It isn’t technically a masonry material itself, but it’s closely related and almost always handled by masonry contractors.
Stucco-clad bungalows, two-flats, and single-family homes are common across Chicago, especially from the 1910s through the 1940s. Done correctly, stucco is an extremely durable cladding system. Done incorrectly — applied over an incompatible substrate, mixed wrong, or installed without proper control joints — it cracks, delaminates, and traps water.
The National Park Service preservation brief on stucco covers historic stucco systems in detail. For modern stucco repair work in Chicago, see our stucco repair service.
Other specialty masonry materials we work with include terra cotta — Chicago’s defining ornamental material on commercial and institutional buildings from roughly 1880 to 1930. Terra cotta is a beautiful, fragile, and demanding material that requires specialized restoration approaches. The NPS preservation brief on terra cotta is essential reading for anyone with a building that has it.
New Construction Masonry vs. Masonry Restoration
New construction masonry builds walls from scratch using current materials and techniques. Masonry restoration repairs, replaces, and stabilizes existing masonry — usually on older or historic buildings where the original construction is decades or centuries old.
Most of our work at Fortune Restoration is restoration. New construction masonry is a different rhythm in some ways — productivity-focused, working from architectural drawings, sequenced with framing, roofing, and other trades on a fixed project schedule.
Restoration is a different beast. We’re looking at existing walls that may be 40, 80, or 120 years old, often with multiple generations of repairs underneath them. Diagnosing what’s actually failing, why it’s failing, and what mortar mix matches the original — that’s the work, and that’s where forty years of doing this in Chicago actually matters.
We also handle the in-between cases: additions where new masonry has to match existing, or partial demolition and rebuild where a section of wall has failed beyond repair.
How to Choose the Right Masonry for a Chicago Project
The right masonry type depends on three things: the building’s structural needs, the climate exposure, and the appearance you’re after — whether you’re matching an existing historic building or starting from scratch.
For new residential construction, brick veneer over wood or steel framing is the most common choice in Chicago and surrounding suburbs. It balances cost, appearance, and durability for the climate. For commercial or institutional work, stone or brick veneer over CMU backup walls is standard. For pure utility — warehouses, garages, foundation walls — exposed or painted CMU does the job at a fraction of the cost.
For restoration work, the rule is simpler: match what’s there. The original builders chose materials that worked for the building, the climate, and the construction methods of their era. Substituting modern materials in historic repairs almost always creates problems that didn’t exist before.

Frequently Asked Questions About Different Types of Masonry
What are the different types of masonry construction?
The main types are brick masonry, stone masonry, concrete block (CMU), and stucco systems. Each is built either as load-bearing solid masonry or as a thinner veneer over a structural frame.
Within each category there are sub-types — dressed vs. undressed stone, structural vs. decorative CMU, soft historic vs. modern fired brick. The right choice depends on the building’s age, structural needs, climate exposure, and aesthetic intent.
What’s the difference between solid masonry and veneer masonry?
Solid masonry walls are structural — the masonry itself carries the building’s load. Veneer masonry is a thinner masonry skin attached to a wood or steel frame that does the actual structural work.
Most Chicago buildings constructed before WWII are solid masonry. Most newer construction is veneer over framing. Both can fail and both can be repaired, but the diagnostic and repair approach differs significantly between the two.
Which type of masonry holds up best in Chicago’s climate?
Quality fired clay brick laid with compatible mortar holds up exceptionally well in Chicago’s freeze-thaw climate. Limestone and granite also perform well. Soft historic brick and untreated CMU need more maintenance.
The material matters less than the mortar compatibility, the quality of the original construction, and the maintenance schedule. A poorly built brick wall fails before a well-built CMU wall, regardless of marketing claims about premium materials.
How long does masonry last?
Quality masonry materials — brick, stone, and concrete block — can last 100+ years with proper maintenance. Mortar joints typically need attention every 25 to 30 years in Chicago’s climate.
The materials themselves outlast the maintenance cycles by a wide margin. Buildings that fail prematurely usually have one of three problems: water infiltration that wasn’t addressed, mortar repair done with incompatible materials, or original construction defects that compounded over time.
What’s the difference between brick masonry and stone masonry?
Brick is fired clay, manufactured to consistent sizes, and the most common masonry material in Chicago. Stone is natural — limestone, granite, sandstone — typically used on commercial, institutional, and high-end residential buildings.
Brick is more economical and easier to source matching replacements for. Stone is more variable, more expensive, and requires more specialized expertise to repair, particularly when matching cut and finish to existing dressed stone.
Can different types of masonry be combined on one building?
Yes. Many Chicago buildings combine masonry types — brick walls with stone trim, limestone facades over CMU backup walls, brick veneer with concrete block foundations. This is standard practice rather than exception.
The challenge is at the transitions where dissimilar materials meet. These joints need flexible sealants, proper flashing, and appropriate detailing to manage differential thermal movement. We see most failures at these transitions rather than within the homogeneous wall sections.
Is concrete block masonry as durable as brick?
Concrete block is structurally durable and cost-effective, but it’s more porous than fired brick and typically requires protection — paint, stucco, or a brick veneer — to weather Chicago’s climate well long-term.
Exposed CMU walls without surface treatment are uncommon in finished construction precisely because of weathering concerns. With proper treatment, CMU is an excellent material — but it’s typically used as the structural backbone behind a more weather-resistant cladding rather than as the finished face of the building.
