Calling a plumber doesn't have to be stressful, and we work to keep it straightforward from the first call to the final walk-through. We cover the full range of residential and commercial plumbing: drain cleaning and clog removal, leak detection and repair, water heater repair and replacement for both tank and tankless units, toilet and faucet and fixture installation, sewer and main line service, garbage disposals, water pressure diagnostics, shutoff valve repair, and whole-home repiping. Whether you manage a rental property across town, run a restaurant on the square, or own a home that needs a fast fix, we treat your home and its pipes the way we would our own. Pick up the phone and we'll handle the pipes.
A slow drain is an early warning. A full clog can back up a kitchen sink, a bathroom floor drain, or an entire main drain line if it goes unaddressed. We clear kitchen drains, bathroom drains, shower and bathtub clogs, and floor drains using the right tools for the job. For stubborn or recurring blockages, hydro jetting flushes the line completely and removes buildup that a standard snake leaves behind. Restored flow, no backup, and a line that stays clear longer.
Hidden leaks do the most damage because they go unnoticed the longest. We locate the source, assess what the pipe or fixture has been through, and repair or replace the affected section before water has a chance to work its way further into the structure. Slab leak detection is part of what we do, and we approach every leak job the same way: find it accurately, fix it properly, and leave the area better than we found it.
No hot water is one of those problems that stops a household or a business in its tracks. We repair and replace both tank-style and tankless water heaters, and the work is performed by licensed plumbers who know the code requirements for your area. Whether the unit is leaking, failing to heat, or simply past its useful life, we can diagnose it, flush it if a flush is all it needs, or swap it out for a new unit the same day in most cases.
A running toilet wastes more water than most homeowners realize, and a dripping faucet adds up fast on a water bill. We repair running toilets, replace worn-out units, fix leaking and dripping faucets, and install new kitchen and bathroom faucets, showerheads, sinks, and bathtub fixtures. The work stops the waste, improves how everything functions, and updates the look of the space at the same time.
When a sewer line backs up, the problem is usually somewhere between the house and the city connection. We clean sewer lines, clear main line clogs, repair root intrusion, and replace damaged sections when cleaning is not enough. Trenchless sewer repair is an option for many jobs, which means less digging and less disruption to your yard. We speak to the line from the house out to the connection point; we do not service the tank or the drain field beyond that.
We also handle garbage disposal repair and installation, whole-house repiping in PEX or copper, galvanized pipe replacement, water pressure diagnostics, pressure regulator replacement, shutoff valve replacement, backflow preventer installation and testing, and gas supply line service to appliances. If something in your plumbing system is not performing the way it should, we want to hear about it. Reach out and we'll get it diagnosed quickly.
We built this business around plumbing work like this, and the specific conditions in Guadalupe County shape what homeowners and property owners deal with most. Expansive clay soils, hard water drawn from the Edwards Aquifer, mature tree canopy in established neighborhoods, and older housing stock throughout Seguin all create recurring plumbing challenges that we know well. The three services below come up regularly here, and we have handled them across the county for decades.
Guadalupe County sees heavy seasonal rain events, and low-lying properties near the Guadalupe River corridor can accumulate standing water in crawl spaces and utility areas during and after those storms. A properly installed sump pump keeps the lowest level of the home dry when water has nowhere else to go. We handle new sump pump installation, replacement of failed units, and pit inspection to make sure the system is ready before the next rain event arrives.
Seguin's established neighborhoods are lined with mature oaks and pecans, and those root systems are always searching for moisture. Sewer lines are a reliable source. Root intrusion is one of the more common causes of slow drains and recurring backups in older parts of town. We clear root intrusion from the line, run a camera inspection to see the full picture, and repair or replace damaged sections using trenchless methods where the line allows it. The goal is restored flow without more excavation than the job actually requires.
The Edwards Aquifer supplies much of the water in this part of Texas, and it carries a high mineral load. Hard water scales pipes, clogs fixture aerators, shortens the life of water heaters, and leaves deposits on everything it touches. A whole-house water softener addresses the problem at the point of entry. We install the softener, connect it to your supply lines, and integrate it with your existing plumbing so the whole house benefits from treated water.
Keeping a home dry starts with the pipes behind the walls, and when one of those pipes fails, the clock starts immediately. Burst pipes, major leaks, sewer backups, and a sudden loss of hot water are not problems that improve with time. We take same-day calls and after-hours calls because that is when these situations happen. Weekends included. We stand behind every pipe and fixture we touch, and we show up prepared to handle the emergency from the first visit. Leak found. Leak fixed. Water back on. We'll get the job plumbed and finished.
If you're not sure your water pressure is where it should be, or if you have a leak you haven't tracked down yet, the last thing you need is to wonder what a plumber visit is going to cost you. We give you the number before the work starts. No-pressure estimates, priced up front, whether the job is a single fixture repair in a Seguin home or a commercial repiping project across multiple units. Residential homeowners and commercial clients both get the same straightforward approach. Call (830) 549-8959 to request an estimate and we will walk you through what the job involves and what it costs.
Property managers, business owners, restaurant operators, and office managers need plumbing work handled quickly and with as little disruption to daily operations as possible. We schedule around your business hours when we can, and we bring the right crew and equipment to get commercial jobs done efficiently.
Commercial work we handle regularly includes:
Licensed plumbers are on the job for every commercial project, and we coordinate directly with property managers and facility contacts to keep the schedule moving.
Plumbing a home right takes the right tools and a licensed hand, and it also takes someone who is accountable to the community they work in. We have been doing this work in Seguin since 1972, and the people on our crew are the same people who answer the phone when you call. We built this business here, and we back every job we do. When something is not right, we come back and make it right. That is what more than five decades in Guadalupe County looks like in practice. Work is performed by licensed plumbers who know local code and take the job seriously. We are proud of the reputation we have built one job at a time across this community.
We serve Seguin and the towns and communities throughout the surrounding region. If you are nearby, we can likely get to you.
Areas we serve include:
Call ahead to confirm service to your address, and we will let you know availability and timing.
Yes, we offer same-day appointments and take after-hours calls when a plumbing problem cannot wait. We are available every day, including weekends, from 9:00 AM to 8:00 PM. If something urgent comes up outside those hours, call us and we will do our best to get someone to you.
We give you the price before any work begins, no-pressure estimates, priced up front, so you know what the job costs before we start. If the scope changes once we open a wall or access a fixture, we tell you before we continue. There are no fees added after the fact for materials or labor that were not discussed.
A standard visit can cover almost anything in your plumbing system: drain cleaning, leak detection and repair, water heater diagnosis, toilet or faucet replacement, sewer line service, water pressure diagnostics, shutoff valve repair, and more. We come prepared for the job you described and bring the tools to handle related issues we find along the way. If the scope turns out to be larger than expected, we walk you through the options before proceeding.
Call (830) 549-8959 and describe what you are dealing with. In many cases we can give you a solid range over the phone before we arrive. Once we see the job in person, we confirm the price and explain what the work involves before anything starts.
Yes, we work with homeowners, landlords, property managers, restaurant operators, office managers, and business owners throughout Seguin and the surrounding area. Residential and commercial clients both get the same upfront pricing and the same licensed plumbers on the job.
We regularly serve New Braunfels, Schertz, Cibolo, Marion, Luling, Gonzales, San Marcos, Kyle, and communities across Guadalupe County. Call ahead to confirm service to your address and we will let you know availability and timing.
In most cases, yes, having someone present makes the visit go more smoothly. The plumber needs access to the affected area, the main shutoff valve, and often the water heater. If you cannot be there yourself, arranging for a trusted adult to be present and available to answer questions is the next best option.
It helps to know the general location of the problem, whether it is a single fixture or something affecting the whole house, and whether the issue is ongoing or just started. If you have had the same problem before, mention that too. The more detail you can share, the better we can prepare for the visit.
Yes, clearing a path to the water heater, the main shutoff valve, and any under-sink areas where work is needed saves time and helps the job move efficiently. Moving stored items, cleaning supplies, or furniture away from those areas before we arrive is appreciated and helps keep the visit focused on the repair.
Payment is typically collected at the completion of the job once the work is done and you have had a chance to confirm everything is in order. For larger projects, we can discuss the payment schedule when we walk through the estimate so there are no surprises.

| Plumbing Service | What the Job Covers | Recommended For | Helpful to Know |
|---|---|---|---|
| Garbage Disposal Service | disposal repair, full unit replacement, electrical and drain connection, jam clearing | A disposal that hums but won't turn, leaks, or has stopped working entirely | Most disposal replacements are completed in a single visit with no advance parts order required |
| Water Softener Installation | whole-house softener installation, supply line integration, existing plumbing connection, point-of-entry setup | Homes on Edwards Aquifer water dealing with scale buildup, short fixture life, or water heater deposits | Hard water shortens the life of water heaters and clogs aerators; a softener at the point of entry protects the whole system |
| Whole-Home Repiping | PEX or copper repiping, galvanized pipe replacement, full supply line replacement, staged or single-visit scopes | Older homes with galvanized or corroded pipes, persistent low pressure, or discolored water | A repipe typically takes one to three days depending on home size; we walk through the scope and timeline before work begins |
| Toilet Repair & Installation | running toilet repair, full toilet replacement, wax ring and flange service, new toilet installation | A toilet that runs, leaks at the base, or needs replacing | A running toilet can waste hundreds of gallons a month, so a prompt repair pays for itself quickly on the water bill |
| Emergency Plumbing | burst pipe response, major leak control, sewer backup service, after-hours and weekend calls | Any plumbing failure that cannot wait for a next-day appointment | We take same-day and after-hours calls every day of the week, including weekends, because plumbing emergencies do not follow a schedule |
| Sewer & Main Line Service | sewer line cleaning, main line clog clearing, root intrusion removal, trenchless repair where the line allows | Multiple drains backing up at once or sewage odor in the home | We service the line from the house out to the city connection point; trenchless methods reduce yard disruption on eligible jobs |
| Slab Leak Detection & Repair | under-slab leak location, non-invasive detection methods, slab penetration repair, rerouting when needed | Warm spots on the floor, unexplained water bills, or the sound of running water with everything shut off | Accurate detection before any concrete work begins keeps the repair targeted and limits the area that needs to be opened |
| Water Heater Repair & Replacement | tank and tankless units, same-day replacement in most cases, flush and diagnostic service, code-compliant installation | No hot water, a leaking unit, or a heater past its useful life | Work is performed by licensed plumbers who know local code requirements for water heater installation in this area |
| Tree-Root Sewer Line Service | root intrusion clearing, camera inspection of the line, damaged section repair, trenchless replacement where eligible | Older Seguin neighborhoods with mature oaks or pecans near the sewer line | A camera inspection after clearing shows whether the line wall is still intact or whether a section needs repair before roots return |
| Water Pressure & Shutoff Valve Repair | pressure diagnostics, pressure regulator replacement, shutoff valve replacement, backflow preventer service | Low pressure throughout the house, a valve that won't fully close, or a pressure regulator past its service life | A failing pressure regulator can quietly damage fixtures and appliances over time; catching it early limits the downstream cost |
| Drain Cleaning & Clog Removal | kitchen and bathroom drains, floor drain clearing, hydro jetting for stubborn buildup, main drain line clearing | Slow drains, recurring backups, or a fully blocked line | Hydro jetting removes grease and mineral buildup that a standard snake leaves behind, so the line stays clear longer |
| Leak Detection & Repair | hidden pipe leak location, slab leak detection, pipe section repair or replacement, fixture leak repair | Unexplained water bills, wet spots, or suspected hidden leaks | Finding the source accurately before opening walls saves time and limits the repair footprint |
| Well Pump Service | well pump diagnosis, pump replacement, pressure tank service, supply line from well to home | Homes on private well water with low pressure, no water, or a pump that cycles constantly | We work the plumbing side of the well system, from the pump and pressure tank through the supply lines into the home |
| Faucet & Fixture Installation | kitchen and bathroom faucets, showerheads and tub fixtures, sink installation, fixture upgrades | Dripping faucets, outdated fixtures, or a bathroom or kitchen refresh | Replacing a worn cartridge or valve seat often costs less than a full faucet swap and stops the drip just as reliably |
| Sump Pump Installation | new sump pump installation, failed unit replacement, pit inspection, discharge line routing | Low-lying properties, crawl spaces, or areas near the Guadalupe River corridor that collect water after heavy rain | Guadalupe County sees intense seasonal rain events; having the system inspected before storm season is the best time to find a weak unit |
How do I know if my water heater needs to be replaced or just repaired?
Age is the first factor. Most tank water heaters last eight to twelve years; tankless units run longer. If the unit is leaking from the tank body, producing rusty or discolored water, or failing to heat even after a diagnostic, replacement is usually the better investment. If the issue is a failed heating element, a bad thermostat, or a valve problem, a repair may restore full function at a lower cost. We diagnose the unit first and walk you through the options before recommending anything.
What causes drains to clog, and when should I call a plumber instead of trying to clear it myself?
Kitchen drains clog from grease, soap, and food particles. Bathroom drains collect hair and soap buildup. A single slow drain is often a localized blockage that a plunger can address. When multiple drains back up at once, when a drain backs up after you run a different fixture, or when a clog returns quickly after clearing, the problem is likely deeper in the line or in the main drain. That is when a plumber with the right equipment makes more sense than another attempt with a store-bought tool.
How are hidden leaks found without tearing out walls?
We use pressure testing, moisture detection, and in some cases acoustic equipment to locate a leak before opening anything. The goal is to identify the source as precisely as possible so the repair is targeted. A slab leak, for example, can often be pinpointed to a specific section of pipe under the floor rather than requiring a broad excavation. Accurate detection up front is what keeps the repair scope manageable.
Upfront Quotes With No Surprise Fees
We give you the number before the work starts, and if the scope changes once we are on the job, we tell you before we continue. You always know what you are agreeing to.
What are the signs of a sewer or main line problem?
Multiple drains backing up at the same time is the clearest sign. Other indicators include gurgling sounds from a toilet when you run a sink, sewage odor inside or outside the home, slow drains throughout the house rather than in one fixture, and wet or unusually green patches in the yard above the sewer line. Any of these warrants a main line inspection. The sooner we look at it, the less likely a partial blockage becomes a full backup.
How do tree roots get into a sewer line, and can the damage be repaired without digging up the yard?
Roots follow moisture, and a sewer line is a reliable source. They enter through small cracks, joint gaps, or aging seals and grow inside the pipe until flow is restricted or blocked. In Seguin's older neighborhoods, mature oaks and pecans make this one of the more common sewer problems we see. We clear the intrusion, run a camera to assess the pipe wall condition, and repair damaged sections using trenchless methods where the line is eligible. Not every job avoids excavation entirely, but we use the least invasive approach the line allows.
What is the difference between a tank and a tankless water heater?
A tank water heater stores a set volume of hot water and keeps it heated continuously. A tankless unit heats water on demand as it flows through the unit, with no storage tank. Tankless units take up less space, have a longer service life, and avoid standby heat loss. Tank units cost less upfront and are simpler to replace quickly. The right choice depends on your household's hot water demand, your existing gas or electrical setup, and your budget. We can walk you through both options when you call.
Work Performed by Licensed Plumbers
Every job, residential or commercial, is handled by licensed plumbers who know local code requirements and take the work seriously.
What causes low water pressure throughout the house?
Low pressure affecting the whole house rather than a single fixture usually points to a few common causes: a failing pressure regulator, a partially closed main shutoff or meter valve, mineral buildup in older galvanized pipes, or a supply line issue. In Seguin and the surrounding area, hard water from the Edwards Aquifer can accelerate scale buildup inside pipes over time, gradually narrowing the flow. We run a pressure diagnostic to identify the source before recommending a repair.
How does pricing work, and will the estimate change once the plumber arrives?
We give you the price before any work begins. No-pressure estimates, priced up front, so you know what the job costs before we start. If we open a wall or access a fixture and find something that changes the scope, we tell you before continuing. You decide whether to proceed. There are no fees added after the fact for labor or materials that were not discussed.
Same-Day and Emergency Availability
We take same-day calls and after-hours calls every day of the week, including weekends, because plumbing problems do not follow a convenient schedule.
Do I need to be home when the plumber arrives?
In most cases, yes. We need access to the affected area, the main shutoff valve, and often the water heater. If you cannot be there yourself, having a trusted adult present who can answer questions and make decisions about the repair is the next best option. For commercial jobs, a facility contact or property manager on site serves the same purpose.
When does a home need repiping, and how long does it take?
Repiping becomes the right call when galvanized pipes have corroded to the point of restricting flow, when leaks are recurring in multiple locations, when water is discolored or has a metallic taste, or when a pressure diagnostic points to widespread pipe degradation rather than a single problem. Most whole-home repipes take one to three days depending on the size of the home and the pipe layout. We walk through the scope and timeline with you before work begins so there are no surprises.
Is same-day or emergency plumbing service available?
Yes. We take same-day calls and after-hours calls because burst pipes, major leaks, and sewer backups do not wait for business hours. We are available every day including weekends. If you have an urgent situation, call us and we will tell you how quickly we can get to you.
Call (830) 549-8959 and tell us what you are dealing with. We will walk you through the options and get the right service on the schedule.
