A Lesson in Traditional Plaster

We were recently chatting internally about Tim McDonald’s home retrofit in Massachusetts, and it sparked a fascinating debate about how much "standard practice" changes based on where you live.

Tim is currently gutting and replacing the interior plaster finish from his exterior walls to add cavity insulation.

In Philly, if you tell a contractor you're doing a "plaster demo," they’ll probably wince. We usually mean the old-school, three-coat horsehair mess over wood lath. It’s brutal, dusty, and heavy.
But at Tim’s house, a 1960s build in Massachusetts, it’s a completely different story. The walls are a veneer plaster over blueboard.

While it’s a much cleaner demo, the real kicker is how they are rebuilding: If you were to frame and finish those walls today in Massachusetts, that same veneer plaster is still the go-to install. It provides a flawless, Level 5 smooth finish with zero sanding required.

We often assume the whole country switched to standard taped gypsum drywall decades ago, but Massachusetts is a fascinating regional outlier. Thanks to a historically strong union presence that preserved the trade, veneer plaster remains a standard there.

It’s a great reminder for architects and builders that "standard practice" isn't a monolith. Sometimes, a regional tradition is actually the superior tech.
