Toilet Replacement

Sometimes, a repair just isn’t enough—you need a fresh start. We handle the full removal and installation of your new toilet cleanly and efficiently, so you’re not left dealing with a half-finished job.

Water Heater Installation

Getting a water heater installed correctly from the start saves you from costly headaches down the road. DeClue Plumbing handles the full installation with licensed expertise, so you get reliable hot water without wondering if the job was done right.

Water Heater Replacement

An aging water heater can go from inconvenient to a flooded utility room faster than most homeowners expect. We assess your situation, recommend the best unit for your home, and get it replaced before a small problem turns into a costly one.

Water Heater Repair

Not every water heater problem needs a full replacement. Strange noises, inconsistent temperatures, and slow recovery times are often fixable, and we give you a straight answer on what it actually needs before recommending anything further.

Tankless Water Heater

Homeowners tired of running out of hot water and paying for energy they’re not using are making the switch to tankless. We help you figure out if a tankless water heater is the right fit for your home and handle the full installation, from recommendation to final hookup.

Case Study

A Decade of Commercial Plumbing Done Right for Lutheran South

See what happens when a St. Louis institution stops overpaying union contractors and finds a plumbing partner that actually gets it right.

Lutheran South came to DeClue Plumbing after years of cycling through larger union contractors for science lab plumbing, boiler replacements, and major mechanical work. The jobs were getting done, but the installations weren’t right, and the school kept paying for it. They didn’t just need a plumber. They needed one they could actually count on.

Our team came in, assessed what had been done wrong, and corrected it to code. Then we kept showing up. Over the years, DeClue has completed science lab installations, locker room upgrades, boiler system replacements, and large-scale commercial builds across the Lutheran South campus. Every job came with a typed estimate, a straight answer, and work that didn’t need a callback to finish what we started. No surprises, no shortcuts, no mess left behind.

More than 100 completed jobs across one of St. Louis’ most recognized schools. Commercial plumbing at roughly half the cost of larger union competitors. And when Lutheran South picks up the phone with a plumbing problem, they call DeClue first. No runaround. No overpaying. Just a contractor that shows up and gets it right.
