When does brick need to be replaced instead of repaired?
Brick should be replaced when it is spalling (flaking and crumbling), cracked through, badly eroded, or missing entirely. Once a brick's hard outer face is gone, it soaks up water and deteriorates fast — and can let water into the wall. Replacing damaged brick and matching it to the original keeps the wall sound and the facade looking right.
What causes brick to spall and crumble in Chicago?
Spalling happens when water gets into the brick, freezes, and pops the face off. Chicago's soft early-1900s common brick is especially prone to it, and the damage accelerates where mortar has failed, gutters overflow, or a hard sealer trapped moisture inside. Fixing the water source is as important as swapping the brick.
Can you match old Chicago brick?
Yes — an experienced mason sources reclaimed or closely matched brick and tints the mortar so replacements blend into the wall. Matching the size, color, and texture of century-old Chicago common brick is a craft, and it is the difference between an invisible repair and an obvious patch.
Frequently Asked Questions
How much does brick replacement cost in Chicago?
It depends on how many brick, the height and access, and how hard the brick is to match. Spot replacement of a few brick is modest; larger areas cost more. A free estimate gives an accurate figure.
Is spalling brick dangerous?
It can be. Beyond letting water into the wall, spalled or loose brick high on a facade or chimney can fall. It should be addressed before it spreads or becomes a safety hazard.
Can you replace brick without rebuilding the whole wall?
Yes. Individual damaged brick can be cut out and replaced without disturbing the surrounding wall, then the joints repointed to match.
