CJ Nielsen walks through the challenges of working in a mid-19th-century home with original lath and plaster walls, comparing the older assembly to modern drywall construction. Speaking from an electrician’s perspective, he explains how plaster systems are thicker, more brittle, and far less forgiving during remodeling work, especially when adding wiring, lighting, or outlets. Nielsen discusses the labor-intensive nature of historic renovations, the importance of setting expectations early with homeowners and builders, and practical techniques for minimizing wall damage during cuts and patching. The conversation centers on preservation, trade coordination, and adapting modern upgrades within historic homes.
