Drain Cleaning

Slow and clogged drains aren’t just annoying — a small clog left alone becomes a bigger one. We clear kitchen sinks, showers and tubs, bathroom sinks, floor drains, and main lines using modern equipment, and when it helps we run a video camera inspection to find exactly where the blockage is and what’s causing it. Grease, coffee grounds, food waste, hair, “flushable” wipes, and paper towels are the usual culprits — and once we’re in there, we’ll tell you how to keep it from happening again. If multiple fixtures back up at once, the problem is usually the line itself.

Pipe Repair, Repiping & New Water Lines

Your pipes are the highway your clean water travels on — when one leaks or bursts, damage adds up fast. We handle pipe repair and replacement, repipe failing runs, and install new water lines and water mains for additions, remodels, and new construction. Pipes fail from tree roots, corrosion and age, freezing, clogs, poor-quality pipe, and ground settling. We also do leak detection and leak repairs — including slab leaks under concrete — and fix low or dropping water pressure and poor water flow as well as outdoor hydrants. Watch for slow or discolored water, dropping pressure, damp spots, or a water bill that jumped for no reason — catching these early keeps the repair small. For older homes on worn galvanized pipe, we repipe to code with a licensed team.

Frozen & Burst Water Pipe Repair

Southern Illinois cold snaps can freeze and burst pipes in a hurry — especially in crawlspaces, exterior walls, and unheated spaces. We get frozen pipes thawed, locate and repair burst pipes, and advise on insulation so it doesn’t happen again next winter. We also handle home winterizing — a smart step for seasonal and second homes, including lake properties, so pipes don’t freeze while you’re away. If you have a burst, shut off your main water valve and call us.

Toilet Repair & Installation

A toilet that won’t stop running, flushes weakly, or leaks at the base wastes water and can rot the subfloor. We fix running/“ghost-flushing” toilets (usually a worn flapper, fill valve, or flush valve), weak flushes, constant clogs, and base leaks — and when a toilet is cracked or chronically clogging, we’ll price a replacement, including modern comfort-height or higher-efficiency models. We can install a fixture you bought or supply one.

Faucet Repair & Replacement

A dripping faucet wastes hundreds of gallons a month and can damage cabinets and counters. We fix faucet leaks, shower leaks, and tub leaks (along with the toilet leaks above) — most drips come from a worn cartridge, O-ring, or aerator, a quick repair. When the fixture is corroded, the finish is failing, or parts are no longer made, replacement is the better value, and we’ll tell you honestly which way to go. Water pooling inside the cabinet often means a supply-line or shutoff issue, so we check the connections underneath too.
