Stillmark Construction is a third-generation family build. My grandfather built. My father builds. We're still building.
The standard hasn't changed — and neither has the kind of work that earns it. Stillmark stays focused on the projects where that standard makes a real difference for a homeowner: wildfire hardening, custom residential, and ADU and garage conversions. If your project lives there, we'd be honored to talk.
