Licensed contractor in Custer County, Colorado

We do more than dig a hole and drop in a tank.

Tri-Lakes Contracting is a licensed septic installer, excavation contractor, and custom home builder working throughout Custer County. Site work and septic permitting are the critical first steps before you can even break ground on a build — and they’re exactly what we handle, start to finish.

Because we hold the septic, driveway, and building sides in-house, we bundle them into one path instead of stitching together three separate contractors: soil testing and engineered design, excavation and grading, the septic system, water storage, and the home itself — one crew, one point of contact, on your schedule.

We know Custer County terrain inside and out — a high valley under the Sangre de Cristos, rocky bench soils, and cold nights. Whether your property is in Westcliffe and Silver Cliff, we deliver site work built for Wet Mountain Valley conditions and permitted under Custer County Public Health and Colorado’s Regulation 43.

What we don’t do

We don’t design or stamp septic systems ourselves — that work is always completed by a licensed engineer. But we work closely with our engineering partners so you receive a complete, permit-ready package that passes Custer County Public Health review the first time, without the back-and-forth that stalls a Custer County build.

Where we work in Custer County

We serve Westcliffe and Silver Cliff and the surrounding Wet Mountain Valley high country, out from Westcliffe. At 7,800–9,000 ft, Custer County brings a high valley under the Sangre de Cristos, rocky bench soils, and cold nights — conditions our crews work in every week, not once a season.
