We Know Your Neighborhood's Plumbing

Plumbing in the Gulf Coast isn't "one size fits all." The soil in Cypress is different from the salt air in Galveston. We tailor our repairs to your specific zone:
  • The "Clay Belt" (Cypress, Katy, Richmond): Shifting clay soil here creates foundation movement that snaps sewer lines. We specialize in Static Isolation Testing to pinpoint slab leaks and perform precision repairs that protect your home's structural integrity.
  • Coastal Zone (Galveston, Bacliff, Seabrook): Salt air corrodes standard tank water heaters and external pipes faster here. We install corrosion-resistant Tankless Water Heaters and hurricane-ready gas shut-off valves to protect your coastal property.
  • Historic Houston (Heights, Bellaire, Pasadena): Older homes often suffer from deteriorating galvanized water lines. We provide complete Whole-Home PEX Repipes and gas line modernization to bring your historic home up to current safety codes.
  • Rural & Outer (Dayton, Liberty, Cleveland): For homes running on well water or sitting off the main grid, water quality is often the biggest battle. We install advanced Water Softeners and Filtration Systems to combat hard water, plus propane lines for standby generators.

Plumbing Services

From dripping faucets to burst pipes, we handle it all. Whether it's a gas line repair in The Woodlands or a Tankless Water Heater upgrade in Sugar Land, our licensed masters get it done right the first time.

Water Heaters

No hot water is an emergency. Whether your tank is leaking or you're ready to upgrade to endless hot water with a tankless system, our trucks carry the thermostats, elements, and gas valves needed to get you back in service fast.

Tankless Water Heater Installation

Tired of running out of hot water? A tankless unit delivers endless hot water and lasts 20+ years. We install Navien and Rheem condensing units sized for your home's demand. Our trucks carry the venting, gas line components, and condensate pumps needed to complete the installation in one day.

Tankless Water Heater Repair

Tankless units require annual descaling -especially in Houston's hard water. We flush the heat exchanger, replace the inlet filter, and test the gas valve. Our vans carry Navien and Rheem service kits, so repairs happen on the spot without waiting on parts.

Tankless Water Heater Replacement

If your tankless unit is beyond repair - cracked heat exchanger, failed gas valve—we replace it same-day. We carry Navien units on the truck for immediate installation. You're not waiting a week for a special order.

Water Heater Repair

No hot water? We diagnose the issue: failed thermostat, burned-out element, or gas control valve. Our trucks carry the components for Rheem, Bradford White, and AO Smith units - we repair it on the first visit and warranty the parts.

Water Heater Replacement

When your tank is leaking or beyond economical repair, we replace it same-day. Our mobile warehouses stock 40-gallon and 50-gallon residential units. We haul out the old tank, install the new one, and verify it's heating properly before we leave.

Gas Services

Gas leaks are life-threatening. Our technicians carry electronic detection equipment and the code-compliant fittings to repair or replace gas lines immediately—we don't leave your home without gas overnight.

Gas Line Repair

A gas leak is life-threatening. We use electronic gas detectors and pressure testing to locate the leak, then repair it with code-compliant black iron pipe or CSST flexible gas line. Our trucks carry the fittings and pipe dope needed to make the repair immediately - we don't leave your gas shut off overnight.

Gas Line Replacement

Old galvanized gas pipe corrodes and leaks over time. We replace it with modern black iron or CSST flexible line that meets current code. Whether you're adding a gas range, fireplace, or generator, we size the line correctly and pull the permit.

Gas Testing

Buying a home with gas appliances? Selling a property? We perform static pressure testing to verify your gas system holds pressure without leaks. We provide documentation that satisfies insurance companies and real estate transactions.

Remodeling

A remodel isn't just about aesthetics - it's about relocating drain lines, upgrading shut-off valves, and ensuring everything is properly vented. We coordinate with your contractor to keep your project moving.

Bathroom Remodel

Outdated fixtures waste water and look terrible. We handle the full scope: new tubs, walk-in showers, vanities, and tile work. We don't subcontract—our licensed plumbers and tile crews work together to deliver a bathroom you'll use for the next 20 years.

Kitchen Remodel

A kitchen remodel isn't just cabinets - it's plumbing for the sink, dishwasher, disposal, and ice maker. We relocate drain lines, upgrade shut-off valves, and ensure your new island has proper venting. Our plumbers coordinate with your contractor to keep the project moving.

Backflow Prevention

Backflow preventers protect your drinking water from contamination. Texas requires annual testing, and many cities now mandate installation for irrigation systems. We handle the testing, repairs, and city paperwork.
More Backflow Services

Backflow Preventer Installation

City water pressure drops during a main break, and contaminated water can siphon back into your drinking supply. A backflow preventer stops that reversal. Many cities now require them for irrigation systems and commercial properties. We install code-compliant devices and handle the inspection paperwork.

Backflow Preventer Repair

If your backflow preventer is leaking or failed the annual test, we carry the replacement parts on the truck: check valves, relief valves, and test cocks. We repair it on the spot and provide the documentation your city requires.

Backflow Preventer Repair

Texas requires annual testing of backflow prevention devices. We perform the test, submit the results to your local water authority, and notify you if any components need replacement. It's a 20-minute service that keeps your water safe and your property compliant.

General Plumbing

From failing galvanized pipes to broken water lines, we handle the repairs that keep your home running. Our trucks carry the PEX, copper, and fittings needed to fix it right the first time.
More Plumbing Services

Toilet Replacement

A constantly running toilet wastes 200 gallons per day. If repairs aren't cost-effective, we replace it with a high-efficiency model. We carry Kohler and American Standard toilets on the truck, so you're back in service within an hour.

House Repipe

If you're dealing with rusty water, low pressure, or frequent leaks, your galvanized pipes are failing. We replace the entire system with PEX piping that flexes with foundation movement and won't corrode. We cut drywall access panels, run the new lines, and patch everything back. Most homes are done in 2-3 days.

Water Line Repair

A broken water line floods your yard and spikes your water bill. We use static isolation testing to pinpoint the leak without excavating your entire lawn. We dig the access hole, replace the damaged section with Type L copper or PEX, and restore your landscaping.

Water Line Replacement

If your main water line is galvanized steel or old polybutylene, it's a ticking time bomb. We replace it with PEX or Type L copper from the meter to your home. The new line is buried below frost line and pressure-tested to 150 PSI before we backfill.

Commercial Plumbing Projects

Office build-outs, restaurant kitchens, and multi-unit apartment complexes require fast, code-compliant plumbing. We manage the entire project: rough-in, inspections, and fixture installation. Our trucks carry commercial-grade components, so your project stays on schedule.

General Plumbing

A slow drain is a warning sign. We use high-pressure hydro-jetting to scour cast iron pipes and camera inspections to spot tree root intrusion before it causes a major sewage backup.
More General Plumbing Services

Camera Inspection

A slow drain is a warning sign. We don't guess—we send a high-definition camera down your line to show you exactly what's blocking it. Tree roots, cast iron corrosion, or a collapsed pipe: we pinpoint the problem before we dig. Our trucks carry the camera equipment, so diagnosis happens on the spot.

Sewer Line Repair

When your main sewer line cracks or shifts, sewage backs up into your home. We perform permanent repairs using tunneling and excavation - not temporary trenchless patches that fail under Houston's shifting soil. Our mobile warehouses carry the static isolation testing equipment needed to pinpoint leaks under the slab without tearing up your entire yard.

Sewer Line Replacement

If your cast iron sewer line has reached the end of its life, we replace it with Schedule 40 PVC that won't rust or corrode. We handle the excavation, permitting, and restoration - including re-sodding your yard. You get a 50-year solution, not a 5-year band-aid.

Sewer Stoppage and Water Jet Service

Kitchen grease and tree roots don't respond to store-bought chemicals. We use industrial hydro-jetting equipment that delivers 4,000 PSI at 18 GPM to scour your main line clean. Our trucks carry the heavy-duty jetter, so we clear the stoppage and verify it with a camera inspection - all in one trip.

Water Treatment Services

Houston water is notoriously hard. Protect your piping, appliances, and skin from scale buildup and chlorine. We install water softeners and whole-home filtration systems customized specifically for local water quality issues.

Water Conditioning Solutions

Houston water is notoriously hard - full of calcium and magnesium that destroy tankless heaters and leave white scale on faucets. We install whole-home water softeners sized for your household. Softened water extends the life of your appliances and makes your skin feel better after a shower.

Water Filtration

City water contains chlorine, chloramine, and trace pharmaceuticals. Well water often has iron, sulfur, or sediment. We install whole-home filtration systems customized to your specific water quality issues. You get clean drinking water from every tap - no more bottled water.

Generator Services

Don't be left in the dark during the next Gulf storm. As authorized Generac dealers, we install and maintain whole-house standby generators that keep your AC and fridge running the moment the grid fails.

Backup Generator

The next Gulf Coast storm will knock out power for days. A backup generator keeps your AC, refrigerator, and medical equipment running the moment the grid fails. We are authorized Generac dealers with generators in stock and ready to install—no 6-month wait times.

Generator Installation

We don't just set a generator on a concrete pad and walk away. We run the gas line, install the automatic transfer switch, and pull the city permit. Our technicians are licensed for both plumbing and electrical work, so your installation is code-compliant and warrantied.

Whole House Generator Installation

A whole-house generator powers your entire home - not just a few circuits. We size the unit based on your electrical panel and gas capacity, then handle the complete installation from start to finish. Whether you're in The Woodlands or Galveston, we install Generac systems designed to withstand hurricanes.
