C-N-I Locates is a local Underground Utility Detection & Inspection Service Company located in and serving Western Washington State including the complete Seattle, Tacoma and Everett metro area.

We specialize in an array of services that are specifically tailored to suit your needs, from public and private utility design surveys, location and identification of leaks, electrical faults, video inspections, concrete & structural imaging and more…

When requesting public utility locates, I’m sure you’re aware that there may also be a number of buried customer owned private utilities on commercial and residential properties as well; these private utilities are not field marked by the public locating services. If you should require any private utility locates, please contact us for scheduling and rate information.
