Calling a plumber doesn't have to be stressful, and working with us is straightforward from the first call. We handle plumbing work for homeowners who need a quick repair and for property managers who need a reliable contractor they can count on across multiple units and buildings. The scope is wide: everyday repairs, new fixture installation, drain cleaning, water heater work, sewer and main line service, repiping, and emergency response.
Residential customers get a licensed plumber at the door who explains what is wrong, what the fix involves, and what it will cost before any work begins. Commercial clients get the same honest approach, plus the experience to work around tenant schedules and keep disruption to a minimum. We bring no-pressure estimates, priced up front, so there are no surprises when the job is done. Reach out and we'll get it diagnosed quickly.
We built this business around plumbing work like this, the kind of job that keeps a household running or a commercial building functional. Below is a look at the core services we provide. Each one is handled by licensed plumbers who know this area's pipe systems, soil conditions, and building stock.
A slow drain is easy to ignore until it stops draining entirely. We clear clogs in kitchen drains, bathroom drains, floor drains, and main drain lines using the right tools for the situation. For stubborn buildup or recurring blockages, hydro jetting is one of the most effective methods available. It uses high-pressure water to cut through grease, scale, and debris without damaging the pipe wall. We diagnose the cause of the clog first, then clear it completely so it does not come back the same week.
Water leaks cause more damage the longer they go unaddressed. We locate leaks in supply lines, under slabs, inside walls, and at fixtures using methods that avoid unnecessary destruction of your property. Slab leak detection and repair is a service we perform regularly in this area, where shifting soil can stress pipes over time. A visit typically starts with a pressure test and a visual inspection, followed by targeted detection to pinpoint the exact location before any work begins. We then repair or replace the affected section and confirm the line is holding before we leave.
No hot water is one of the most disruptive plumbing problems a household faces. We repair and replace both tank and tankless water heaters, and we carry the experience to diagnose a failing unit accurately. Sometimes a repair extends the life of a heater by several years. Sometimes the unit is too far gone and replacement is the smarter call. We explain the difference honestly and give you the information you need to decide. We install new tank and tankless units and handle the gas line and water line connections that go with the job.
A running toilet can waste a significant amount of water before most people notice it. A leaky faucet drips money down the drain every day. We handle toilet repair and replacement, leaky faucet repair, kitchen and bathroom fixture upgrades, and garbage disposal installation. If you are remodeling or just replacing an aging fixture, we do the installation correctly the first time so the connection holds and the finish looks right.
A sewer backup is not a problem you can put off. We clear main line clogs, inspect sewer lines, and repair or replace damaged sections of the line that runs from your home to the city connection. We work on the line itself: clearing it, repairing it, and replacing it when necessary. We stand behind every pipe and fixture we touch, and that applies to the sewer work as much as anything else we do.
Keeping a home dry starts with the pipes behind the walls, and when one of those pipes fails, the damage moves fast. We are available around the clock for plumbing emergencies in Seguin and the surrounding area. Burst pipes, major leaks, a water heater that stopped working overnight, a sewer backup that is backing up into the house: these are the calls we take at any hour. We also offer same-day scheduling for urgent situations that are not full emergencies but cannot wait a week for an appointment.
Leak found. Leak fixed. Water back on.
When you call, you speak with someone who knows the area and can get a licensed plumber moving toward your address. We do not ask you to wait for a callback window that stretches into the next business day. Pick up the phone and we'll handle the pipes.
Nobody wants to be surprised by a bill that is twice what they expected. Before we start any job, we walk you through what the work involves and what it will cost. If the scope changes once we open a wall or pull a fixture, we tell you before we continue. That is the only way to run an honest plumbing business.
Getting a quote starts with a phone call. We ask a few questions about what you are dealing with, and in many cases we can give you a solid range before we arrive. Once we see the job in person, we confirm the price. There is no pressure to approve work on the spot, and there are no fees added after the fact for materials or labor that were not discussed. We'll get the job plumbed and finished on terms you agreed to from the start.
Every plumbing job we take on is performed to code. Licensed plumbers on every job means the work meets the standards that protect your home, your family, and the value of your property. This matters especially for commercial clients who need documentation and for homeowners who plan to sell. Plumbing that was done right the first time does not become a problem during an inspection.
We also keep up with the materials and methods that reflect current standards. Older homes in Guadalupe County sometimes have aging galvanized or polybutylene pipe that has reached the end of its useful life. We handle whole-home repiping for those situations, replacing the old system with durable modern materials and doing the job in a way that minimizes disruption to the household.
Plumbing a home right takes the right tools and a licensed hand, and it also takes familiarity with the local water supply, the soil, and the way homes in this part of Texas are built. We have been working in and around Seguin for 54 years, and that experience shows in how quickly we diagnose problems and how accurately we estimate the work.
Beyond Seguin, we regularly serve customers in New Braunfels, Schertz, Cibolo, Luling, San Marcos, and the communities spread across Guadalupe County. If you are close enough to call us a local plumber, we want to be the first number you reach for. We'll get the job plumbed and finished wherever you are in the area.
We have been doing this work in Seguin since 1972, which puts us past the 54-year mark. The business was founded by a father-and-son team who grew up in Guadalupe County and learned the trade from the ground up. That history means we know the homes, the soil, the water, and the community in a way that only comes with decades on the job.
We work with homeowners, renters, landlords, property managers, restaurant operators, office managers, and commercial building owners throughout Seguin and the surrounding area. The job might be a single dripping faucet in a home on the east side of town or a full repipe across a multi-unit rental property. We approach both with the same standards and the same upfront pricing.
The people who answer the phone are connected to the same crew that shows up at your door. We are a locally owned operation, and the plumbers on our team are licensed professionals who know this area and take the work seriously. You are not dealing with a rotating roster of unfamiliar faces.
Yes, work is performed by licensed plumbers on every job, residential and commercial. That matters because licensed plumbers know the code requirements for this area, perform the work to those standards, and protect the value and safety of your property.
We built this business here, and we back every job we do. That means honest pricing before the work starts, showing up when we say we will, and coming back if something is not right. We treat your home and its pipes the way we would our own, and that standard has not changed in 54 years.
When you call during our operating hours, 9:00 AM to 8:00 PM every day, you reach a real local person who can answer questions and get a plumber moving toward your address. For urgent situations, same-day service is available. We do not ask you to wait for a callback window that stretches into the next business day.
Seguin has a wide range of housing stock, from older homes in established neighborhoods with aging galvanized or cast-iron pipe to newer construction with modern materials. We have worked on both ends of that spectrum for decades and know the common failure points in each. That familiarity helps us diagnose problems faster and give you an accurate picture of what the repair or replacement involves.
We stand behind every pipe and fixture we touch. If a problem comes back because of the way the work was done, we come back and make it right. We are straightforward about what is covered when we give you the estimate, and we do not make promises we cannot keep.
If something we repaired is not holding up the way it should, call us. We assess the situation honestly, and if the issue traces back to our work, we fix it without turning it into a billing dispute. That is what more than five decades in this community looks like in practice.
For more than 54 years, Kelso Plumbing has been the plumber Seguin and Guadalupe County residents and businesses trust when the pipes need attention. We are locally owned, personally accountable, and ready to take your call today. We treat your home and its pipes the way we would our own, and that commitment is the same whether you need a faucet swapped out or a full emergency response at two in the morning.
Call (830) 549-8959 to request a quote or schedule service. You schedule it. We fix it. Simple as that.
We handle the full range of residential and commercial plumbing in Seguin and across Guadalupe County. From a dripping faucet to a full sewer line replacement, every job gets the same upfront pricing and the same licensed plumbers on the call. The table below covers what each service includes, who it fits best, and a practical note to help you decide what you need.
| 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.
