The Hard Part of Brick Repair Isn’t the Fixing — It’s the Matching
Anyone with a trowel can swap out a broken brick. The craft is making the repair invisible — matching color, texture, size, and the mortar joint profile so the new work disappears into a hundred-year-old façade.
Shamrock handles the full scope: spalled and damaged brick replacement, lintel repair or replacement above windows and doors, structural brick repair for cracks and bulging walls, and period-matched brick sourcing for historic Chicago buildings. One crew start to finish — not a dispatcher and a subcontractor.
What Fails on a Brick Wall
Brick Doesn’t Just Wear Out — Something Makes It Fail
Healthy brick can last well over a century. When you see spalled faces, cracks, or bulging walls, it’s almost always traceable to a specific cause — and fixing the brick without fixing the cause is money wasted.
Water in the wall freezes, expands, and blows the face off the brick. Failing mortar, caulk, or flashing is almost always the upstream cause of spalled brick.
Steel lintels above windows and doors rust and expand up to 10× their original thickness — lifting and cracking the brick above them. Very common on Chicago homes from the 20s–70s.
Differential settlement under a foundation shows up as stair-step cracks through the mortar and brick. Stabilize the cause, then the wall stays fixed — otherwise the crack comes right back.
Our Brick Repair Process — Diagnose, Match, Complete
We diagnose the cause before quoting the fix. Our crew sources matching brick, executes the repair, and hands you a quality workmanship before we leave.
Personal Assessment
We inspect the damage in person to assess condition and plan the repair. No sales pitch, just a clear explanation.
Match the Brick
We pull samples and source brick that matches your existing color, size, and texture. For older buildings we have suppliers specializing in period-matched and reclaimed Chicago common brick.
Repair + Root Cause
Damaged brick is cut out and replaced. Lintels are repaired or swapped. Structural cracks are stabilized. Then we address the cause — caulking, flashing, waterproofing — so the fix actually lasts.
Clean-Up & Completion
Debris hauled, work area washed down, quality workmanship on every brick we touched — handed to you in writing before we leave.
“Our 1920s bungalow had a stretch of spalled brick and a rusted lintel above the front window. Shamrock matched the brick so well you can’t tell what’s new. The lintel is sound, the wall looks original. Pros from start to finish.”
Common Questions, Answered
Can you actually match the brick on my older home?
What causes brick to spall (the face popping off)?
My lintel is rusting — what’s the actual fix?
I have stair-step cracks. Is it structural?
Why am I getting such a big price difference in quotes?
Shamrock doesn’t work that way. We’re a family-owned company with our own crew. One of the owners walks the wall with you, we source the right brick ourselves (from our own stock or from the salvage yards we’ve used for years), and the same Shamrock masons who quoted the job do the repair. No sub layer, no markup, no mismatched patch.
