Saving your stonework when others fall short.
Saving your stonework when others fall short.
The Forensic Scene: The Death of a Limestone Balustrade I was called to a job site last spring where a homeowner was in tears over a historic limestone balustrade restoration project. From twenty feet away, it looked like the stone had a skin disease. Up close, it was worse. A ‘handyman’ had used a 4,000 […]
The Forensic Scene: When a Hairline Crack Becomes a Structural Autopsy The homeowner called me out to look at what they described as a ‘minor cosmetic issue’ on their 1920s brick facade. From the sidewalk, it looked like a standard case of weathered joints. But the moment I climbed the scaffolding and pressed my thumb […]
The Black Crust: More Than Just Grime When I walk up to a limestone building that has been sitting in an urban corridor for eighty years, I don’t just see a dirty wall. I see a slow-motion chemical war. That black, soot-like skin clinging to the protected areas of the cornices and window headers isn’t […]
The Tragedy of the Blasted Brownstone I remember standing on a scaffold in the rain, looking at a 19th-century facade that had been ‘cleaned’ by a handyman with a 4,000-PSI power washer. The man thought he was doing the homeowner a favor by stripping away the soot. Instead, he had literally skinned the building. The […]
The Forensic Scene: When the Crust Conceals a Catastrophe The homeowner thought it was just a hairline crack. But when I put my scope inside the cavity of that 1908 brownstone, I saw the structural steel was rusted to dust, expanded to three times its original thickness, and was literally Jacking the stone facade off […]
I walked onto a site last Tuesday where the so-called specialist had used a 40-grit blast on a late 19th-century facade. It looked like the building had been pelted with birdshot at point-blank range. The homeowner thought they were getting a fresh look, but instead, they had effectively sandpapered the life out of the masonry. […]
The Forensic Reality of Decaying Stone The homeowner thought it was just a hairline crack, a minor blemish on a century-old legacy. But when I put my scope inside that fissure, I saw the structural steel lintel was rusted to dust, expanding with the force of oxidized iron and pushing the stone out by three […]
The Forensic Scene: A Facade Stripped of Its Soul I walked up to a 1910 Queen Anne in a historic district last October where the owner was beaming with pride. He’d just spent twelve thousand dollars having the ‘grime’ removed from his exterior. As I ran my hand over the wall, my palm didn’t meet […]
The building manager thought it was just a bit of peeling paint on the 14th-floor lintels. But when I got up there on the swing stage and put my borescope into the cavity, I saw the structural steel angle was rusted to a flakey, orange dust, expanding with enough force to heave three courses of […]
The White Ghost in the Wall I’ve spent thirty years watching buildings sweat. To the untrained eye, those chalky white streaks on a commercial facade are just a bit of ‘old building character.’ To me, it’s a forensic crime scene. That white powder—efflorescence—is the building’s way of screaming that it’s drowning from the inside out. […]
