Theo Marchetti
Writes the estimating and materials pages
Theo spent twelve years estimating masonry jobs — takeoffs, mortar math, and the awkward conversations when a bond pattern doubled the labor line.
Writes About
- Bond patterns and coursing
- Materials, mortar, and what they cost
- Reading old construction manuals so you don’t have to
He collects out-of-print construction manuals and started Isodomos (the Greek term for coursed ashlar) to put what they know back into circulation, drawn to scale and priced honestly.
“A wall is arithmetic you can lean on. Most masonry advice online skips the arithmetic; these pages start with it.”
