A homeowner once hired me after he’d rented a gas pressure washer and blasted his limestone garden wall at full pressure to knock off the green algae. It worked — for about a week. Then chunks of the soft face started flaking off where the water jet had chewed into the stone, and the joints … Read more
I got called out to a beautiful travertine entryway once where the owner had mopped the whole floor with straight lemon cleaner, thinking a “natural” acid would cut the grime. Within a week the surface had dull, cloudy patches everywhere the cleaner pooled — the acid had eaten into the stone and etched it. That … Read more
The fastest way to ruin a polycarbonate window is to grab the glass cleaner under your sink and go at it. I’ve watched a homeowner spray an ammonia-based cleaner across a conservatory panel, wipe it down, and stand back proud — only to see a web of fine cracks bloom across the surface a week … Read more
A client once called me in a panic because the brand-new glass balustrade around her staircase looked permanently smeared no matter how much she wiped it. She’d been going at it with a dry paper towel and a supermarket spray, buffing the same greasy fingerprints back and forth into a foggy haze. The glass wasn’t … Read more
A homeowner once handed me a spray bottle of blue ammonia cleaner and asked why her grandmother’s church-salvaged window kept looking cloudier every year.

She’d hung a metal stocking holder off the mantel over the holidays, it got damp, and the iron leached straight into the porous stone.

A client once called me in a panic because she’d vacuumed out her fireplace two days after her last fire, thought the ashes were cold, and melted the inside of her shop vac into a plastic-and-ember mess on the garage floor. Those coals had been buried under a gray blanket of ash, quietly holding heat … Read more
A homeowner once handed me a bottle of bathroom tile spray and asked why her beautiful stacked-stone hearth had turned chalky and pale in patches. The acid in that cleaner had eaten straight into the natural stone, leaving dull white etching that no amount of scrubbing could reverse. That’s the number one way people ruin … Read more
