Why MAINLINE

Straightforward work. No games. No surprises.

Thirty years in the ground under the Wasatch Front. We know Utah soil, Utah code, and what it takes to do the job right the first time.

Same- or next-day service

Most jobs start same-day or next-day from your initial call — and once we start, we stay on the job until it's done. We keep the trucks stocked so we can move when you need us to.

Straightforward, transparent pricing

Free on-site estimates and an honest upfront price. Underground work can surprise anyone, so when a variable cost comes up we tell you about it before we do the work — no pressure, no games.

10-year guarantee

A full 10-year guarantee on parts and workmanship, within any manufacturer's warranty limits. We stand behind every job we do.

Licensed & insured

Utah General Engineering and General Plumbing contractor. Fully insured. Locally owned. Residential and commercial work welcome.
