About Slateco

Our Services

  Slateco handles excavation, utility work, and concrete/ADA upgrades for public agencies, school districts, and private clients alike. Public projects come with strict standards, and we've built our processes around meeting them consistently — so whether it's a city contract or a private job, you get the same careful, reliable work. 

Our Team

 Slateco's crew — along with the trusted subcontractors we partner with — shows up ready to work. Operators, tradespeople, and project managers who know their equipment and know the job. We treat every site like it's our own, because a job well done is the only kind we're interested in. 

Our Mission

 At Slateco, we show up, do the work right, and leave the job site better than we found it. Safety and precision aren't extras — they're how we operate on every project, public or private. And if you ask our owner, even the toughest sewer line job is "easy and fun" — we bring that same attitude to everything we take on. We work hard and laugh often — usually at the same time. 

GROUNDED IN PRECISION. dRIVEN BY RELIABILITY.
