How It Works
Our high-pressure hydro-jetting system blasts through grease, scale, tree roots, and debris that ordinary snaking leaves behind. We start with a camera inspection to pinpoint the blockage, then use water jets at up to 4,000 PSI to scour the pipe walls clean. This restores full flow, eliminates odors, and helps prevent future backups — all without digging or damaging your pipes. Perfect for kitchen sinks, bathroom drains, main sewer lines, and commercial grease traps.

How It Works
Plumbing emergencies don't wait for business hours, and neither do we. Our emergency response team is fully stocked and on call 24/7/365 — when you call, a real plumber answers and dispatches immediately. We handle burst pipes, major leaks, gas line breaks, sewer backups, water heater failures, and flood damage. Every truck carries the tools and parts to handle 95% of emergencies on the first visit, so you're not waiting for a follow-up. We arrive, diagnose, and fix — fast.

How It Works
Austin's hard water leaves mineral buildup in pipes, stains fixtures, wears out water heaters, and dries out skin and hair. We install whole-home water softening systems sized precisely to your household's water usage and hardness level. The process starts with a free water quality test at your home. We then recommend the right system — salt-based ion exchange, salt-free conditioners, or dual-tank systems for large homes. Installation includes a dedicated loop, drain line, and bypass valve so you can isolate the softener for maintenance without shutting off water to the house. We also offer ongoing salt delivery and annual service plans to keep your system running at peak efficiency.

How It Works
Old, corroded, or leaking pipes don't always mean tearing up your floors and yard. We offer trenchless pipe lining (CIPP) — a cured-in-place epoxy liner inserted into the existing pipe and inflated, creating a new pipe within the old one. For homes needing a full repipe, we use PEX or copper depending on your preference and budget, with a typical 2–3 day timeline. We handle slab leak detection with electronic listening devices and thermal imaging, so we pinpoint the leak before cutting. Every repipe comes with a transferable warranty and passes city inspection.

How It Works
We install and service all types: traditional tank heaters (gas and electric), energy-efficient tankless/on-demand units, and hybrid heat-pump water heaters. Our technicians assess your household's hot water demand — number of bathrooms, appliances, peak usage times — to right-size the unit so you never run out mid-shower. We handle gas line modifications, venting upgrades, expansion tanks, and permit coordination. Same-day replacement is available for emergencies, and we offer annual flushing and anode-rod inspection to extend the life of your existing unit.

How It Works
A hidden leak can waste thousands of gallons and cause structural damage before you ever see a wet spot. We use advanced acoustic listening devices, thermal imaging cameras, and helium tracer gas to locate leaks with pinpoint accuracy — no guesswork, no unnecessary demo. Once found, we present repair options from spot-fix to full line replacement, with transparent pricing upfront. Common jobs include slab leaks, irrigation line breaks, pool line leaks, and mysterious high water bills where the source isn't obvious.

Whether you're remodeling a kitchen, refreshing a bathroom, or replacing a worn-out water heater, our fixture installation service covers the full range. We install undermount, farmhouse, and vessel sinks; touchless and pull-down faucets; low-flow and comfort-height toilets; continuous-feed and batch-feed garbage disposals; and custom shower systems with body sprays, rain heads, and thermostatic valves. Every install includes a leak test, proper sealing, and a walkthrough of operation and maintenance. We also handle gas appliance hookups for ranges, dryers, and outdoor grills.
