Martin G Plumbing has served residential homeowners, landlords, property managers, and commercial clients across San Antonio and Bexar County since 2011. When a pipe leaks, a drain backs up, or a water heater stops producing hot water, you need a plumber who picks up the phone and shows up ready to work. We offer same-day availability on most calls and give you a clear estimate before any work begins. No runaround on pricing, no vague answers.
We pick up the phone. We arrive on time. We test before we leave.
Trusted by local homeowners and property managers for their plumbing, we bring the same level of care to a single-family home in Alamo Heights as we do to a commercial property in the heart of the city.
A properly plumbed home is a worry-free home, and that starts with having a reliable contractor who handles the full range of plumbing repair and installation work. We cover drain cleaning and clog removal, leak detection and repair, water heater service for both tank and tankless units, toilet and faucet repair, fixture installation, sewer and main line service, garbage disposals, water pressure issues, shutoff valves, and whole-home repiping. Whether you need a single fixture swapped out or a full plumbing contractor for a renovation, we handle code-compliant work from the meter to every fixture in the building.
Slow drains and full blockages happen in sinks, showers, bathtubs, and main lines. We clear clogs using the right tool for the job, including hydro jetting for stubborn grease or mineral buildup that a snake alone won't touch. Clearing the line properly restores full flow, prevents backups from spreading, and protects the interior of your pipes from long-term damage. We service individual drains and main line drain cleaning for the whole property.
Hidden leaks are the ones that cost the most. Water quietly working behind a wall or under a slab can cause serious structural damage before it ever shows up on the surface. We use non-invasive detection methods to locate pipe leaks, water line leaks, and slab leaks before opening walls or floors unnecessarily. Finding the leak early stops water damage in its tracks and brings your utility bills back down. Reach out and we'll start at the source of the leak.
A no-hot-water call is one of the most disruptive plumbing problems in any home or building. We diagnose the issue first, repair the unit when that's the right call, and replace aging water heaters when repair no longer makes sense. We install both traditional tank units and tankless water heaters sized for your household or facility. Work is performed by licensed plumbers, and we make sure the installation meets local code before we close out the job.
A running toilet wastes more water than most people realize, and a leaking faucet adds up fast on a water bill. We repair and replace toilets, install kitchen and bathroom faucets, and handle sink, shower, and bathtub installation. Outdoor faucets and hose bibs are part of the picture too. Every fixture installation we do is code-compliant and tested before we leave. Upgrading a fixture is also a straightforward way to improve function and stop waste at the same time.
A sewer backup is one of the few plumbing problems that can affect an entire property at once. We clear main sewer line clogs, repair damaged sewer lines, and replace sections of line that have deteriorated past the point of repair. Our work covers the line from the house out to the city connection. Keeping that line clear and intact is what prevents sewage from backing up into the home or building. We also handle main water line repair when the supply side needs attention.
A garbage disposal that won't run, low water pressure across the house, or a shutoff valve that no longer closes fully are all plumbing problems that affect daily life. We repair and replace garbage disposals, diagnose low water pressure at the source, and replace shutoff valves throughout the property. For older homes with deteriorating pipe, whole-house repiping is the long-term fix that restores reliable water flow and water quality from every tap. We also install backflow preventers where required. We'll get the job plumbed and finished.
Here's what most people get wrong about their plumbing: they assume a general repair is all they need without considering what the local environment is doing to their pipes over time. San Antonio's heavy clay soils shift foundations and stress underground lines. Water from the Edwards Aquifer is among the hardest in Texas, and that mineral load shortens the life of pipes, heaters, and fixtures. Established neighborhoods across the city carry aging infrastructure that needs attention. The three services below address the plumbing challenges that come up most often in this area.
Low-lying areas in and around San Antonio can see serious water intrusion during the intense flash flooding that Hill Country rain events produce. A properly installed sump pump protects a basement or crawl space by moving water out before it causes damage. We size the pump to the space, position the pit correctly, route the discharge line away from the foundation, and test the system before we leave. If your property is in a flood-prone area or you've had water intrusion before, a sump pump is worth the conversation.
San Antonio's mature live oaks, pecans, and other established trees are part of what makes older neighborhoods so appealing. They're also a leading cause of slow drains and sewer backups. Tree roots follow moisture, and a small crack in a sewer line is enough of an invitation. We clear root intrusion from the line, run a camera inspection to assess the full condition of the pipe, and give you an honest read on whether a repair or a full sewer line replacement is the right call. We speak only to the line itself, from the house to the city connection, and we'll tell you exactly what we find.
San Antonio water is hard. The Edwards Aquifer delivers high mineral content that leaves scale in pipes, builds up inside water heaters, and shortens the life of fixtures across the home. A whole-house water softener addresses the problem at the supply line before the water reaches anything else. We size the system to your household's demand, connect it properly to the supply line, and test water quality before and after so you can see the difference. One ring and we're on the way.
You shouldn't have to chase a plumber for answers on what a job is going to cost. Before we start any work, we give you a clear estimate that covers the scope of what we're doing. Drain cleaning, leak repair, water heater replacement, repiping, and every other job we handle comes with straight answers about your pipes and fixtures, no surprises after the invoice. We know that cost is part of the decision, and we'd rather you understand the number upfront than be caught off guard when the work is done. Call for a quote and we'll give you a real number to work with.
The hardest part of a plumbing problem is knowing when to call, and the answer is usually sooner than you think. A burst pipe, a major leak, a sewer backup, or a home with no hot water are not situations to wait on. We offer same-day service on most calls and respond quickly when the situation is urgent. Prompt response, even for last-minute plumbing calls, is part of how we operate. You should not have to wait days for a plumber when water is actively causing damage.

Yes, and we do it regularly across San Antonio and Bexar County, where a lot of the housing stock carries galvanized or older pipe that has reached the end of its useful life. We assess the condition of the existing pipe, repair what can be repaired, and recommend whole-home repiping when patching no longer makes sense. We'll give you a straight answer on what the pipe actually needs before any work begins.

Yes. We operate seven days a week, including Saturday and Sunday. Whether you need a scheduled repair on the weekend or an urgent call on a Sunday evening, you can reach us at (726) 200-5632 and we'll get someone out to you.
When you call, we schedule a time that works for you and show up when we say we will. We assess the problem, explain what we found, and give you a clear estimate before any work starts. Once you approve the scope, we complete the repair, test everything, and confirm the fix is holding before we leave.
The estimate we give you covers the scope of work we've agreed on, including labor and the parts needed to complete the repair or installation. If something unexpected comes up once we're into the job, we stop and talk to you before going further. You won't see charges on the invoice that weren't discussed upfront.
Absolutely. Telling us where the problem is, what you've noticed, and how long it's been going on helps us get to the source faster. The more detail you can share when you call or when we arrive, the more efficiently we can diagnose and fix the issue.
A targeted repair is the right call when the pipe or unit is otherwise in good condition and the problem is isolated. When we're seeing recurring leaks, persistent low pressure, or a water heater that's failing repeatedly, replacement usually saves more money over time than continuing to patch. We'll give you an honest read on which direction makes sense for your situation.

How do I know if my water heater needs to be repaired or replaced?
Age is the first thing we look at. A tank unit that is more than ten years old and showing problems is usually a better candidate for replacement than repair. If the unit is younger and the issue is isolated, a repair often makes sense. We diagnose the unit first and give you a straight answer on which direction saves more money over time. We do not push replacement when a repair will do the job.
What is the difference between a tank water heater and a tankless unit?
A tank unit stores a set volume of heated water and keeps it ready around the clock. A tankless unit heats water on demand as it flows through, which means it does not run out the way a tank can during high-demand periods. Tankless units tend to have a longer service life and lower standby energy use, but the upfront installation cost is higher. We can walk you through which option fits your household size and usage before you decide.
What causes drains to slow down or back up?
Most clogs in individual drains come from hair, soap buildup, grease, or food debris depending on which fixture is involved. When multiple drains in the house are slow at the same time, the problem is usually further down in the main line. In San Antonio, tree roots from mature live oaks and pecans are a common cause of main line slowdowns in older neighborhoods. We locate the blockage and clear it with the right tool, whether that is a snake or hydro jetting for tougher buildup.
Upfront Quotes With No Surprise Fees
We give you a clear estimate before any work starts and we stick to it. If something unexpected comes up, we stop and talk to you before going further.
How do you find a hidden leak without tearing up walls or floors?
We use non-invasive detection methods that let us locate the source of a leak before we open anything. For slab leaks, we use listening equipment and pressure testing to pinpoint where the pipe is failing under the concrete. That approach limits how much material needs to be disturbed and keeps the repair targeted. We explain what we find before any work begins.
How do I know if a clog is in one fixture or in the main sewer line?
If only one drain is slow, the blockage is likely in that fixture's trap or the branch line serving it. When multiple drains throughout the house are backing up at the same time, or when flushing a toilet causes water to rise in a nearby tub or sink, the main sewer line is usually where the problem is. We can tell you quickly which situation you are dealing with and clear the right section of the line.
What does low water pressure usually mean?
Low pressure at a single fixture is often a clogged aerator or a partially closed shutoff valve at that fixture. When pressure is low throughout the whole house, the cause is usually a failing pressure regulator, a partially closed main shutoff, or buildup inside the supply lines. San Antonio's hard water accelerates mineral buildup in regulators and valves, so this comes up more often here than in areas with softer water. We diagnose the source and fix it at the right point.
Same-Day and Emergency Availability
We offer same-day service on most calls and respond quickly when the situation is urgent. Prompt response, even for last-minute plumbing calls, is part of how we operate.
Do I need to be home when the plumber arrives?
For most jobs, yes. We need access to the work area and we give you a clear estimate before starting, which means someone needs to be available to walk through the scope with us. If you are a property manager coordinating access for a tenant, we can work with you on scheduling and communicate directly with whoever is on site. Just let us know the situation when you call.
How does pricing work and will I know the cost before work starts?
We give you a clear estimate before any work begins. That estimate covers the scope we have agreed on, including labor and parts. If something unexpected comes up once we are into the job, we stop and talk to you before going further. You will not see charges on the invoice that were not discussed upfront.
Work Performed by Licensed Plumbers
Every job we take on is handled by licensed plumbers and completed to code. We test the work before we leave so you know it is holding.
When does it make sense to repipe a home rather than keep repairing leaks?
When a home has galvanized or older pipe that is producing recurring leaks, persistent low pressure, or discolored water, patching individual spots usually costs more over time than addressing the pipe throughout the house. We assess the condition of the existing pipe and give you an honest read on whether a targeted repair or a full repipe makes more sense for your situation. Repiping is a bigger job upfront, but it restores reliable flow from every tap and stops the cycle of repeated repairs.
How does tree root damage happen and what does the repair involve?
Roots follow moisture, and a small crack or joint gap in a sewer line is enough of an entry point. Once inside, roots expand and can eventually block the line entirely. We clear the root intrusion, run a camera inspection to assess the full condition of the pipe, and give you an honest assessment of whether a repair or a section replacement is the right call. We work the line from the house to the city connection and will tell you exactly what we find.
What should I do if a pipe bursts or I have a major leak?
Shut off the water at the nearest shutoff valve you can reach, or at the main shutoff if the leak is large. Then call us. We offer same-day service on most calls and respond quickly when the situation is urgent. While you wait, keep people away from standing water and, if the leak is near any electrical panel or outlet, do not enter the area until the power is confirmed off. The sooner we can get there, the less damage the water can do.
Call (726) 200-5632 and we will walk you through what the job involves, give you a real number to work with, and get you scheduled.
