Drain Cleaning & Clog Removal
Slow drains and clogs that keep coming back usually mean there’s a bigger problem in your pipes. That’s why we use professional-grade equipment to find and fix blockages the right way. We start with a video inspection to see exactly what’s causing the issue. From there, we use drain snaking for typical clogs or hydro jetting for stubborn buildup, grease, and tree roots. And we don’t just clear the clog—we figure out why it happened so you can avoid the same problem down the road.
Water Heater Services
Most water heaters last 8-12 years with regular maintenance, so keeping up with service can save you from an unexpected cold shower. We work on all types and brands, including tank and tankless models. For tank units, we handle anode rod replacement, sediment flushing, thermostat calibration, and element repairs. For tankless systems, we offer descaling, flow sensor cleaning, and error code diagnosis. If your water is slow to heat, looks rusty, or your unit is making strange noises, it’s time to give us a call.
Leak Detection & Repair
Hidden leaks can waste thousands of gallons of water every year and cause serious damage to your home. That’s why finding them fast matters. We use pressure testing to confirm there’s a leak, then acoustic detection and thermal imaging to pinpoint the exact location—even behind walls or under concrete. Once we find it, we make repairs with as little disruption to your property as possible. Common culprits include supply lines, toilet valves, faucet cartridges, water heater fittings, and outdoor spigots.
Toilet Repair & Replacement
A running toilet can waste over 200 gallons of water a day, which adds up fast on your water bill. We fix all kinds of toilet problems—running or cycling toilets, weak flushes, leaks at the base, and cracked tanks or bowls. If your toilet is beyond repair, we can install a new water-efficient model that saves water without sacrificing performance. Either way, we’ll get things working properly and help you stop wasting water and money.
