Plumbing services for Warrenton homes & businesses
From a single dripping faucet to a collapsed sewer line, we handle the full range of plumbing work for Warren County properties. Most calls fall into one of these:
Plumbing repair
Leaks, low water pressure, running toilets, faucet and fixture repair, garbage disposals, and shut-off valves, all diagnosed and fixed right the first time.
Drain cleaning
Clogged sinks, tubs, floor drains, and main lines cleared with cabling and hydro-jetting, plus camera inspection to find the real cause.
Water heaters
Repair, replacement, and new installs for gas, electric, and tankless units. See our water heater repair and installation options.
Sewer & main lines
Sewer line repair and replacement, main stack work, and clearing main-line stoppages before they back up into the house.
Code corrections
Older Warren County homes often need updates to meet current code. We bring aging systems up to standard cleanly.
Frozen & burst pipes
Missouri winters are hard on rural plumbing. We thaw, repair, and help prevent frozen and burst pipes fast.
Why Warrenton calls Authority first
Most plumbers serving Warrenton are dispatching trucks from St. Charles or St. Louis County, 30 to 45 minutes east. We’re headquartered in Warrenton, so a local call doesn’t sit behind a long drive. That matters when a line is backing up or a pipe has burst.

Sewer line repair in Warrenton, MO
A slow main drain, gurgling toilets, or sewage backing up into the lowest fixtures usually points to a sewer line problem like roots, a sag, or a break. We run a camera to locate the issue exactly, then repair or replace only what’s needed. On older Warrenton properties and rural lots, we also handle main stack repair and clean-out installation so future service is simpler.
Water line repair in Warrenton, MO
Sudden pressure drops, discolored water, or a wet spot in the yard often trace back to a failing water line. We repair leaking and corroded supply lines, replace aging poly or copper runs, and handle full re-pipes when a patch won’t hold. If your water bill jumped without explanation, a hidden line leak is a common cause, and we’ll track it down and fix it.
