Lemont has a distinctive built environment shaped by its history as a quarry town. The Illinois-Michigan Canal corridor, the historic downtown, and the older residential neighborhoods along the Des Plaines River valley include masonry construction you won't find in most Chicago suburbs — local Lemont limestone, early 20th-century common brick, and combinations of stone and brick in commercial and institutional buildings that require a contractor who understands material compatibility.

Emerald Masonry LLC handles brick repair and replacement for residential and commercial properties throughout Lemont and Will County. We've been working with older and unusual masonry in the southwest suburbs for over 40 years.

What "Brick Repair" Actually Covers

The term gets used loosely. Here's what it means in practice:

Spalling repair is the most common request. Brick spalling is when the face of a brick unit pops off, leaving the rough interior exposed. It happens when water enters the brick and freezes — the expansion cracks and ejects the face. Spalled brick needs to be removed and replaced; you can't patch a spalled face back on. Individual unit replacement is the right fix when the underlying cause (mortar joint failure, failed caulk, compromised coping) has also been addressed.

Structural crack repair involves horizontal, vertical, or stair-step cracking in the wall. Stair-step cracks running diagonally from window and door corners indicate lintel failure. Horizontal cracking along bed joints can indicate wall movement or poor drainage. Vertical cracks at building corners or mid-wall often reflect settlement or thermal expansion. Each pattern points to a different cause and a different repair scope.

Wall section rebuilding is needed when damage has progressed beyond individual unit replacement — when multiple courses have been saturated, when freeze-thaw cycling has loosened brick from the wall, or when structural movement has shifted a section. This work requires removing the affected courses, addressing the underlying cause, and relaying brick to match the original coursing and bond pattern.

Brick matching is where a lot of contractors fall short. On Lemont properties — especially older commercial buildings, churches, and residential construction in the historic district — replacement brick needs to match the original in color, texture, size, and surface finish. We source from regional brick suppliers and salvage yards. For Lemont limestone elements, we have suppliers who can match common limestone profiles used in the area's historic construction.

Common Causes of Brick Damage in Lemont

Lemont's location near the Des Plaines River means its older building stock sees more moisture exposure than properties further from the river valley. The combination of ground moisture, periodic flooding history in low-lying areas, and Will County's standard freeze-thaw cycling creates accelerated deterioration conditions for masonry built before modern drainage standards.

On hillside properties — common in Lemont given the valley topography — water management around the building foundation affects masonry performance. Water draining toward the building saturates ground-level brick and mortar, accelerating deterioration from the bottom up.

For commercial properties along Main Street and the Route 53 corridor, wind-driven rain from the west is the primary exposure concern. West-facing walls consistently deteriorate faster than east-facing walls on the same building.

Our Brick Repair Process

Every job starts with a thorough assessment. We look at:

Which brick units are damaged and why (spalling, cracking, displacement)
Whether the damage pattern indicates an active water source that needs to be addressed
The mortar joint condition across the affected area
Whether lintels or other structural elements contributed to the problem
What replacement brick will be needed and where to source it

We don't start cutting out brick until we've identified the cause of the damage. Replacing brick over a failed lintel, for example, produces a repair that re-cracks within a few years. The underlying issue has to be part of the scope.

Damaged units are cut out carefully using chisels and oscillating tools to avoid damaging adjacent brick. The cavity is cleaned, new brick is set in fresh mortar matched to the existing type, and joints are finished to match the original profile. On larger repairs, we wet-cure mortar for 48–72 hours.

Historic and Older Masonry Considerations

Pre-1950 brick construction in Lemont often used softer clay brick with lime-based mortar. These walls have different mechanical properties than modern masonry — the mortar is intentionally softer than the brick, allowing movement to occur in the joints rather than the units. Repair work on these walls must use compatible soft mortar; modern Portland cement-heavy mixes will cause spalling and cracking in the adjacent original brick.

We specify mortar mixes based on the age and composition of the existing masonry, not a one-size-fits-all formula.

Frequently Asked Questions

How do I know if my Lemont property's brick needs repair or just tuckpointing? If mortar joints are the only issue — recessed, cracked, but brick faces are intact — tuckpointing is the right scope. If you're seeing brick faces that have popped or chipped, brick that sounds hollow when tapped, or sections where brick has shifted or separated from the wall plane, you need brick repair. Our free site assessment will tell you exactly what's needed.

Can you match the brick on my older Lemont home or building? Usually yes, though it takes more effort on older properties. We'll source samples from suppliers and salvage yards and do a visual match. On very old or unusual brick, we may do a test placement first and get your approval before completing the repair. A visible color mismatch on a historic building is something we take seriously.

How much does brick repair cost in Lemont? Individual unit replacement (cutting out and replacing 1–10 damaged units) typically runs $150–$350 per unit depending on accessibility and mortar type. Larger repair areas — 20–50 units or more — are priced by the square foot and run $35–$80 per square foot of repaired wall including mortar and matching. Wall section rebuilding is priced by the linear foot of rebuilt wall. Our $5,000 project minimum applies to all work. We provide free written estimates.

Do you handle brick repair on commercial properties in Lemont? Yes. Commercial brick repair — storefronts, light industrial, institutional buildings — is a significant part of our work. We handle documentation, coordinate around tenant occupancy, and can work within property management timelines. We also provide written before/after documentation for insurance and ownership records.
