Masonry Maintenance

The Ghost of the Great-Uncle: A Lesson in Resilience My great-uncle once took me into the cellar of a 19th-century distillery. The walls were weeping, but the structure was as sound as the day it was laid. He reached out and scraped a bit of the mortar with his thumbnail. It didn’t crack like glass; […]

I remember the forensic scene like it was yesterday. A homeowner in a high-end suburban lot had spent nearly ten thousand dollars on a custom outdoor living space, but his centerpiece—a massive, circular masonry fire pit—was nothing more than a glorified ash tray. Every time he lit a match, the yard filled with a thick, […]

The Ghost in the Machine: Bridging the Gap Between Ancient Mud and Digital Stone I remember my uncle standing over a pile of reclaimed red clays on a job site in Philadelphia back in 1984. He’d pick up a brick, hold it to his ear, and give it a sharp rap with the wooden handle […]

The Ghost in the Wall: Resurrecting Fire-Damaged Stone Masonry The homeowner stood in the skeleton of what used to be a Victorian parlor, pointing at a soot-stained granite fireplace. To them, it was just dirty. But when I pulled my forensic scope and looked into the deep fissures, I didn’t see soot; I saw a […]

When someone calls me to discuss upgrading an old outdoor fireplace with a new stone mantle, they usually think they’re talking about aesthetics. They’re thinking about the […]

The Ghost in the Wall: Why Most Repointing Fails I remember my uncle kneeling in the damp shadow of a 1880s textile mill, his hands calloused and permanently stained with the grey dust of a thousand jobs. He didn’t look at the brick; he looked at the dust eroding from the joints. He took a […]

The Forensic Scene: When Walls Commit Suicide I was called out to a Victorian estate where the homeowner was distraught over what they called ‘exploding bricks.’ From the curb, it looked like a standard case of age, but as I got closer, the tactile reality of the failure became clear. I ran my hand over […]

The facility manager pointed to a tiny hairline fracture in the CMU wall of a four-story commercial warehouse, dismissing it as a cosmetic nuisance. He thought a bit of silicone caulk would suffice. But when I inserted my borescope into the cavity, the reality was a forensic nightmare: the internal structural steel had oxidized to […]

I stood on a swaying cherry picker seven stories above a downtown sidewalk, looking at a decorative terra cotta cornice that looked perfectly fine from the street. The building manager thought I was wasting his time—until I tapped it. The hollow, dead thud told me everything I needed to know. I reached into a hairline […]
