Licensed contractor in Chaffee 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 Chaffee 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 Chaffee County terrain inside and out — valley alluvium framed by the Collegiate Peaks, with rocky bench ground. Whether your property is in Salida, Buena Vista, Poncha Springs and Nathrop, we deliver site work built for Upper Arkansas Valley conditions and permitted under Chaffee County Environmental 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 Chaffee County Environmental Health review the first time, without the back-and-forth that stalls a Chaffee County build.

Where we work in Chaffee County

We serve Salida, Buena Vista, Poncha Springs and Nathrop and the surrounding Upper Arkansas Valley high country, out from Salida. At 7,000–9,000 ft, Chaffee County brings valley alluvium framed by the Collegiate Peaks, with rocky bench ground — conditions our crews work in every week, not once a season.
