How commercial tenant improvements works with Prolific.

Every Prolific commercial tenant improvements project in King County follows the same path: a 60-second AI estimate, a photo upload that tightens it to ±8%, a 30-minute walkthrough that locks the final price, and then we build to that number.

  1. Basic intake — 60 seconds

    An AI estimate priced from real completed King County jobs. ±15%, no salesperson, no phone tag.

  2. Photo upload — 2 minutes

    Send photos and the number tightens to ±8%. We arrive ready instead of guessing on site.

  3. Walkthrough — 30 minutes

    Every property gets walked. The walkthrough number is the number — that is what you sign.

  4. We build

    Written scope, Prolific crew, and the price you locked at the walkthrough. No change-order theater.

What you get. Always.

Every Prolific commercial tenant improvements project includes code compliance review, landlord coordination, permit + inspection management — written into the scope before work starts, not sold as an upgrade later.
