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.
Our process is simple and direct. Each step keeps you informed from first call to final walkthrough.
Call us or send an email to describe your project. We listen to your goals and answer your first questions.
We visit your home to measure, inspect the work area, and talk through options. You get a clear, written estimate with no pressure.
Our crew starts work as agreed, with the owner staying involved from start to finish. We keep you informed about progress and any changes.
We review the finished work with you, address any concerns, and clean the site. Our team follows up to make sure you are satisfied.
The owner stays hands-on with every project. You always know who is in charge of your work.
