How it works

From walk-through to turnover

  1. Walk the space

    Send us the address and the lease or move-in date. We’ll walk it with you.

  2. Scope, schedule, bid

    We price the work and build the schedule back from your move-in date.

  3. Build

    One point of contact runs the job, with daily updates on scheduling and a clean, safe site.

  4. Punch and turnover

    We work through the punch list with you and close the job out.

City permit and inspection timing is set by the city, not the contractor. We plan the schedule around it.
