Calling a plumber doesn't have to be stressful, and when you call Kelso Plumbing, you reach a locally owned business that has been serving Seguin and Guadalupe County since 1972. We handle residential and commercial plumbing from routine repairs to full installations, and we treat your home and its pipes the way we would our own. Work is performed by licensed plumbers who know this area, know the homes here, and show up ready to solve the problem. Whether you need a same-day fix or want to plan a bigger project, we are available and ready to help. Pick up the phone and we'll handle the pipes.
We work with homeowners, landlords, property managers, and business owners across Seguin and the surrounding area. On the residential side, that means everything from a dripping faucet or a running toilet to a full bathroom remodel or a whole-home repipe. If you are remodeling a kitchen or adding a bathroom, we handle the rough-in and finish plumbing so the work meets code and holds up for years.
For commercial clients and property managers, we understand that a plumbing problem in a rental unit or a multi-unit building is not just an inconvenience. It is a liability. We work efficiently, communicate clearly, and keep disruption to a minimum. We offer no-pressure estimates, priced up front, so you know what to expect before any work begins. Reach out and we'll get it diagnosed quickly.
Keeping a home dry starts with the pipes behind the walls and the lines running beneath the ground. Slow drains, backed-up sinks, and main line clogs are some of the most common calls we get, and we clear them with the right equipment for the job. For stubborn blockages, we use hydro jetting to scour the inside of the pipe rather than just push the clog further down the line.
When the problem is deeper, in the main sewer line running from the house toward the city connection, we diagnose it accurately and give you a clear picture of what repair or replacement looks like. Where trenchless sewer repair is an option, we use it to minimize digging and disruption to your yard. For homes with aging galvanized or cast-iron pipe, whole-home repiping replaces the old system with durable modern materials that will not corrode or restrict flow.
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, that is worth a call. Low pressure can mean a partially closed shutoff valve, a failing pressure regulator, a corroded section of pipe, or something more serious. We diagnose the cause and fix it at the source rather than masking the symptom.
Leak detection is part of that same diagnostic work. A leak under a sink is straightforward. A leak inside a wall or beneath a concrete slab is harder to find and harder to ignore. Slab leaks are a real concern in Central Texas, where expansive clay soils shift with moisture and can stress pipes over time. We cover slab leak detection and repair in more detail in the local services section below, but the short version is: we find it, we fix it, and we stand behind every pipe and fixture we touch. Shutoff valve repair and replacement rounds out this cluster. A valve that will not fully close is a problem waiting to happen, and we replace them cleanly and correctly.
A water heater that stops working is not a minor inconvenience. For homeowners, it disrupts daily life. For a rental property or commercial building, it can mean unhappy tenants or a compliance issue. We repair and replace both tank-style and tankless water heaters, and we help you choose the right unit for your household size, your usage patterns, and your budget.
Tank water heaters are the most common type we service. We handle element failures, thermostat problems, sediment buildup, and full replacements when the tank has reached the end of its life. Tankless units require different service skills, and the licensed plumbers on our team are trained on both. If you have no hot water right now, that qualifies as an urgent call. Reach out and we'll get it diagnosed quickly.
We built this business around plumbing work like this: the everyday repairs and installations that keep a home or building running the way it should. If something is leaking, running, dripping, or just worn out, we replace it right.
Common calls include:
Texas weather means outdoor faucets and hose bibs get year-round use, so we keep those in good working order too. We'll get the job plumbed and finished.
Seguin sits in a part of Texas where the geology, the tree canopy, and the weather each create specific plumbing demands. Expansive clay soils shift with the rain cycle and put stress on buried lines. Mature oak and pecan trees line older neighborhoods and send roots toward any pipe joint they can find. Guadalupe County draws its water from limestone-filtered aquifers, which means mineral content runs high. And when heavy rain moves through the Hill Country, low-lying properties along the Guadalupe River corridor can see water intrusion that a pump has to handle fast. These are the conditions we work in every day.
Seguin and the surrounding river corridor can see intense rainfall in a short window, and low-lying properties fill up quickly when the ground is already saturated. A sump pump installed in a basement or crawl space moves that water out before it causes damage to flooring, framing, or stored belongings. We install new sump pump systems, replace units that have reached the end of their service life, and repair pumps that are running but not keeping up. If your property has flooded before or sits in an area prone to water intrusion, a properly sized and installed sump pump is one of the most practical investments you can make.
The mature pecan and live oak trees that give Seguin neighborhoods their character also send aggressive root systems toward any source of moisture underground. Older clay and cast-iron sewer lines are especially vulnerable because roots can enter through joints and cracks and grow until the line is partially or fully blocked. We clear root intrusions using the right tools for the depth and condition of the line, including hydro jetting for stubborn root masses. Where a section of line is damaged beyond clearing, we repair or replace it, and we use trenchless methods where the site allows to keep your yard intact. We speak to the line only, from the house to the connection point, and we leave the rest to the right trade.
Water in Guadalupe County is naturally hard. It picks up calcium and magnesium as it moves through the limestone geology of the Edwards Aquifer, and that mineral content accumulates inside pipes, water heaters, and fixtures over time. Scale buildup shortens the life of a water heater, reduces flow through supply lines, and wears out faucet cartridges and valve seats faster than they should wear. A water softener installed at the point of entry addresses that mineral load before it reaches your plumbing. We handle the plumbing connections involved in a softener installation, tie it into your supply system correctly, and make sure the bypass valve and drain line are set up properly. The result is less scale, longer fixture life, and a water heater that performs closer to its rated lifespan.
We handle gas line work on the supply side: running new gas lines, repairing existing lines, and making connections for appliances like water heaters, outdoor grills, and kitchen ranges. If you smell gas or suspect a leak in a gas line, that is an urgent call. We locate the problem, make the repair, and confirm the line is sound before we leave.
Backflow prevention is required in many commercial applications in Texas and is a smart addition on residential properties with irrigation systems or other cross-connection points. We install and repair backflow preventers to keep your potable water supply protected. Pick up the phone and we'll handle the pipes.
Plumbing emergencies do not wait for business hours. A burst pipe, a major leak, or a complete loss of hot water needs attention now, not next week. We offer same-day and after-hours service for urgent situations, and when you call, you reach a real local person who knows Seguin and can get someone to your door quickly.
You schedule it. We fix it. Simple as that.
We built this business here, and we back every job we do. Call (830) 549-8959 to report an emergency or to schedule service at a time that works for you.
Plumbing a home right takes the right tools and a licensed hand, and it also takes knowing what you are dealing with before work begins. If you are buying a home in Seguin or Guadalupe County, a pre-purchase plumbing inspection tells you the condition of the supply lines, the drain system, the water heater, and the fixtures before you close. If you are planning a renovation or an addition, we assess the existing system and give you a clear picture of what the project requires.
We offer no-pressure estimates, priced up front, for repairs, replacements, and new installations. There are no surprises in the invoice if you know the scope going in. Whether you are a homeowner planning a bathroom remodel or a property manager evaluating a building before a lease renewal, call for a quote and we will walk you through what we find. Reach out and we'll get it diagnosed quickly.
We offer same-day and after-hours service for plumbing emergencies, including burst pipes, major leaks, sewer backups, and sudden loss of hot water. When you call, you reach a local person who can get a licensed plumber moving toward your address. We are available every day from 9:00 AM to 8:00 PM, and we take urgent calls outside those hours when the situation cannot wait.
A burst pipe, a major active leak that is causing water damage, a complete sewer backup inside the home, or a sudden total loss of hot water all qualify. If the problem is actively damaging your property or making the home unusable, call us right away. For slower-developing issues, a same-day or next-morning appointment is usually the right path.
A clog in one fixture, a single sink or toilet, usually points to a localized blockage in that drain. When multiple fixtures back up at the same time, or when you see water coming up from a floor drain when you run the washing machine, the problem is likely in the main line. We diagnose the location before we start clearing so we use the right method and do not miss the actual source.
A persistent sewer smell indoors often points to a dry trap, a cracked drain line, or a venting problem that is allowing sewer gas to enter the living space. It can also indicate a partial blockage that is holding standing water in the line. We locate the source of the odor, assess the drain and vent system, and repair what is causing it rather than masking the symptom.
In older Seguin neighborhoods, root intrusion from mature oaks and pecans is one of the most common culprits. Roots enter sewer lines through joints and cracks and accumulate until flow is restricted. Grease and scale buildup in kitchen lines is another frequent cause. We clear the blockage and, where root intrusion is involved, inspect the line to assess whether a section needs repair or replacement.
A drain snake breaks up or pulls out a clog, but it does not clean the pipe wall. Hydro jetting uses high-pressure water to scour the inside of the line, removing grease, scale, and root debris that a snake leaves behind. It is more thorough for stubborn or recurring blockages and leaves the pipe significantly cleaner, which means the line stays clear longer.
Recurring leaks in different parts of the house, consistently low water pressure, discolored or rusty water, and pipes that are visibly corroded or made of aging galvanized material are all signs the system may be near the end of its useful life. Older homes in Guadalupe County sometimes have galvanized or polybutylene pipe that has reached that point. We assess the system and give you an honest picture of whether targeted repairs or a full repipe makes more sense.
A section repair addresses a specific failure point: a corroded joint, a cracked length of pipe, a leaking connection. A full repipe replaces the entire supply system, typically because the pipe material throughout the home has aged to the point where failures are happening in multiple locations. We help you weigh the cost of repeated repairs against the one-time investment of replacing the system so you can make an informed decision.
After completing a repair or installation, we run the system and check the affected area for any sign of leakage before we close up or leave. For water line work, that typically means pressurizing the line and confirming it holds. We do not consider the job done until the repair is confirmed to be holding under normal operating conditions.
When we open a wall or access a system and find something that does not meet current code, we let you know what we found and what bringing it up to standard involves. We do not perform work that leaves a known code violation in place, and we explain the requirement clearly so you understand why the correction is necessary. Licensed plumbers on the job means the work is done to the standards that protect your home and its value.
Clear out the cabinet under any sink where work is being done, including cleaning supplies, stored items, and anything stacked in front of the water heater or main shutoff valve. If the water heater is in a closet, make sure the area in front of it is accessible. A clear work area helps the plumber get to the job faster and reduces the chance of anything being moved or damaged during the visit.
Yes, keeping children and pets out of the work area is important for their safety and helps the job move without interruption. Plumbing work often involves turning off water, working under pressure, and using tools in tight spaces. A clear area lets the plumber focus on the job and finish it correctly.
The estimate we give you covers the scope of work as we understood it at the time. Additional charges can come up if we find a related problem once we access the pipe or fixture, such as a corroded fitting behind the wall or a shutoff valve that fails when we try to close it. We always describe what we found and get your approval before doing any work beyond the original scope.
Homes built several decades ago may have galvanized steel supply lines that have corroded from the inside, narrowing the pipe diameter and restricting flow. Older fixtures and valves also wear out over time. The clay soils in this part of Texas shift with the seasonal rain cycle and can stress buried lines and connections. We diagnose the specific cause rather than guessing, so the fix addresses the real problem.

| 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.
