Family built,
community rooted

Masis Contractor LLC started as a one-man operation. The founder picked up tools, showed up on time, and did the work himself. Every job was personal because there was no one else to hand it off to. That kind of accountability shaped everything about how we operate today.

Over the past two decades, something changed. The business grew, and so did the family. Now the founder's kids work alongside him on job sites across the greater Seattle area. What began as a solo effort has become a family business built on the same values it started with: honest work, straight talk, and showing up when we say we will.
