Struck Masonry: Loading Docks, Bollards, Garage Corners, and the Repairs That Actually Hold
Weather damages masonry slowly and predictably. A truck damages it in one second — and the repair is a different job, because the wall will be hit again.
What Happens to Masonry in a Vacant Building — and Why Two Winters Cost More Than Ten Occupied Ones
An empty brick building doesn't just sit there. Heat goes off, gutters stop being cleared, a roof leak goes unnoticed for a season, and masonry that would have lasted another forty years starts failing on a schedule nobody is watching.
Why Masonry Estimates Change Mid-Job: Hidden Conditions, Change Orders, and How to Tell an Honest One From a Bait-and-Switch
Masonry is the only trade where you cannot see the work until you have started destroying it. That makes some change orders genuinely unavoidable — and makes the dishonest ones very easy to hide behind the honest ones.
Graffiti on Brick: Why Fast Removal Beats Aggressive Removal — and What Actually Works
The instinct after finding graffiti is to blast it off. That instinct has permanently ruined more Chicago brick than the graffiti ever did — because the paint comes off the surface, and so does the surface.
After a Fire: What Heat Actually Does to Brick, Mortar, and Stone — and How Masonry Gets Restored
Masonry survives fires that destroy everything around it, which is exactly why it gets misjudged afterward. A wall that looks sound can be calcined behind the face, and a wall that looks ruined is often just sooted. Telling them apart is the whole job.
Birds, Bees, and Squirrels: What Wildlife Actually Does to Chicago Masonry
Animals don't attack masonry — they move into it. Every one of them exploits something that had already started to fail, which makes an infestation one of the most reliable early warnings a building gives you.
Manufactured Stone Veneer Is Failing All Over Chicagoland — Here's Why, and What Actually Fixes It
The stone wainscot on the front of your 1990s or 2000s house probably is not stone. It is a thin cement casting glued to a wall, and when it was installed without a weep screed, run down to the dirt, or built with a single layer of building paper, it does not just fall off — it rots the framing behind it first. Here is how to tell what you have and what a correct repair involves.
Sagging Brick Arches Over Windows and Doors: Why They Drop, and What It Takes to Put One Back
A brick arch carries the wall above your window without any steel at all — it works purely by pushing sideways into the masonry on either side. When an arch starts to sag, drop a keystone, or open at its joints, something has stopped resisting that sideways push. Here is how arches actually work, what makes them fail, and why rebuilding one is a genuinely different job from tuckpointing.
They Tore Down the House Next Door and Now My Brick Is Cracked: Adjacent Construction Damage to Masonry
Excavation, demolition and pile driving next door can crack masonry that stood fine for a century — and on Chicago's tight lots, your wall may have been relying on the building that just disappeared. Here is what actually causes the damage, how to document it before and during, who is responsible, and what a real repair involves.
Why the Top of Your Chimney Always Fails First — and How Far Down the Damage Really Goes
Chimney deterioration is never evenly distributed. It is worst at the top course and improves steadily on the way down, and that gradient is the most useful diagnostic tool a homeowner has. It tells you why the damage happened, whether you need a repoint or a rebuild, and — the question that decides the price — how far down the mason has to go.
Gutters, Downspouts and Grading: The Cheapest Masonry Repair You Will Ever Make
Most brick damage in Chicagoland is not caused by weather. It is caused by water that weather delivered and the house then mismanaged — a clogged gutter, a downspout dumping at the wall, mulch piled over the weep holes, grade sloping the wrong way. Fix the water and the masonry stops failing. Repoint without fixing the water and you have bought yourself about five years.
Brick Pillars, Porch Columns and Entrance Monuments: Repair or Rebuild?
Freestanding masonry — porch piers, fence pillars, mailbox columns, subdivision entrance monuments — fails faster than any wall on your property, and for a reason nobody explains: it is wet on every face, it has no building behind it to dry it out, and most of it was built on a footing that does not go deep enough. Here is how to tell what can be saved and what has to come down.
