Houston Plumbing Services

When you need reliable plumbing services in Houston, you want a team that shows up on time, diagnoses problems accurately, and fixes them right the first time. Since 1984, John Moore Services has been that team for thousands of Houston-area homeowners across Harris, Fort Bend, and Montgomery Counties.

Our licensed plumbers handle everything from simple faucet repairs to complex sewer line replacements. We’ve worked in every type of property across the Houston metro area, from historic homes in the Heights to new construction in Katy, from high-rise condos in downtown Houston to sprawling estates in The Woodlands.

Houston’s unique climate and soil conditions create specific plumbing challenges. Our expansive clay soil shifts with changes in moisture, putting stress on pipes and foundations. Hard water from local sources damages fixtures and appliances. These aren’t problems you can trust to just anyone; you need plumbers who understand Houston.

Drain Cleaning and Clog Removal

Slow drains turn into completely blocked drains very quickly. Tree roots infiltrate older sewer lines throughout Houston neighborhoods. Grease, hair, and soap buildup create stubborn clogs that store-bought chemicals can’t touch. We use professional-grade equipment, including hydro-jetting and mechanical snaking, to clear drains and restore proper flow. Our video camera inspections show exactly what’s causing the blockage, so we can prevent it from happening again.

Water Heater Repair and Replacement

Nothing disrupts your morning routine like a cold shower. We repair and replace both traditional tank water heaters and modern tankless systems. Whether your water heater is leaking, making strange noises, or simply not producing hot water, our technicians diagnose the issue and present your options clearly. We install energy-efficient models that reduce utility bills while providing reliable hot water for your entire household.

Slab Leak Detection and Repair

Slab leaks are widespread in Houston because of our soil conditions. When pipes beneath your concrete foundation start leaking, you might notice warm spots on your floor, unexplained water bills, or the sound of running water when everything’s turned off. We use electronic detection equipment to locate slab leaks without unnecessary demolition. Our repair methods include spot repairs, repiping, and epoxy pipe lining, depending on your specific situation.

Sewer Line Repair and Replacement

Houston’s older neighborhoods often have clay or cast-iron sewer lines that have reached the end of their lifespan. Tree roots from the massive oaks and pines throughout our area seek out moisture and break into aging pipes. We provide video sewer line inspections to assess condition, then execute repairs using traditional excavation or trenchless technology, depending on your property and budget.

Kitchen and Bathroom Plumbing

absolutely me of your kitchen or bathroom? We handle all the plumbing aspects, relocating supply lines, installing new fixtures, running gas lines for ranges and cooktops, and ensuring everything meets current Houston building codes. We work directly with homeowners and coordinate with contractors to keep projects moving smoothly.

Whole-Home Repiping

Many Houston homes built before 1990 have galvanized steel pipes that corrode from the inside out. If you’re dealing with low water pressure, discolored water, or frequent leaks, whole-home repiping might be your best solution. We replace old plumbing with modern PEX or copper systems, typically completing the work in 2-3 days with minimal disruption to your daily routine.

Gas Line Installation and Repair

Our licensed technicians install and repair natural gas lines for water heaters, furnaces, ranges, dryers, outdoor kitchens, and pool heaters. Gas line work requires specific licensing and expertise; we have both. Every gas line installation includes pressure testing and inspection to ensure safety.

Water Filtration and Treatment

Houston’s municipal water is treated and safe to drink, but many homeowners prefer additional filtration to improve taste and remove minerals that damage appliances. We install whole-home water softeners, reverse osmosis systems, and point-of-use filters customized to your water quality and household needs.

Fixture Repair and Replacement

Leaky faucets, running toilets, and malfunctioning garbage disposals waste water and increase utility bills. We repair or replace all types of plumbing fixtures throughout your home. Whether you’re upgrading to low-flow fixtures to save water or replacing a broken component, we complete the work efficiently and guarantee it won’t leak.

Service Areas Throughout the Houston Metro

John Moore Services provides Houston plumbing services to homeowners and businesses throughout the metropolitan area. Our plumbers work daily in Sugar Land, Katy, The Woodlands, Pearland, Spring, Cypress, Tomball, Missouri City, League City, Humble, Pasadena, and Friendswood.

We serve Houston’s inner-loop neighborhoods, including the Heights, Montrose, River Oaks, Memorial, Bellaire, West University Place, the Galleria area, the Medical Center, the Museum District, and Midtown. Our trucks regularly run routes through Cinco Ranch, Energy Corridor, Clear Lake, Kingwood, Atascocita, and surrounding communities across Harris, Fort Bend, Montgomery, Brazoria, and Galveston counties.

Why Houston Homeowners Choose John Moore Services

Houston has no shortage of plumbing companies. Here’s what makes us different: we’ve been serving this community since 1984. Our technicians live in the neighborhoods we serve. They understand Houston’s plumbing challenges because they deal with the same issues in their own homes. Every plumber who arrives at your property is licensed, background-checked, and trained on the latest plumbing technology and techniques. We invest heavily in continuing education because plumbing codes, materials, and best practices evolve constantly. We provide upfront pricing before starting work. No hidden fees, no surprise charges, no time-and-materials billing that leaves you wondering what the final cost will be. You approve the price, and then we complete the job. Our service vehicles carry extensive parts inventory so we can complete most repairs in a single visit. We don’t tell you we need to order parts and come back next week unless absolutely necessary.

We protect your property with floor coverings, respect your home, and clean up completely when we finish. These should be standard practices, but we know from customer feedback that many plumbing companies skip these basics. Our warranties protect both labor and materials. We stand behind our work and return at no charge if something doesn’t perform as expected within the warranty period.

Plumbing Issues Common to Houston Properties

Houston’s climate and geography create specific plumbing challenges. Understanding these helps you recognize problems early and avoid expensive damage. Our expansive clay soil swells when saturated and shrinks during droughts. This constant movement stresses pipes, causes foundation shifts, and leads to slab leaks and sewer line breaks. Properties built on pier-and-beam foundations often experience sagging, which can put pressure on drain lines. Hard water throughout the Houston area contains high mineral content, particularly calcium and magnesium. These minerals accumulate inside pipes, reduce water flow, damage water heaters, and leave white residue on fixtures. Water softeners significantly extend the life of your plumbing system and appliances. Tree roots cause more sewer line damage in Houston than almost anywhere else. Our long growing season and adequate rainfall produce massive root systems that infiltrate. If you built your home before 1990 and it still has its original plumbing, it’s likely nearing or surpassing its expected service life. Houston neighborhoods have aging infrastructure. Galvanized steel pipes corrode, cast iron sewer lines deteriorate, and Orangeburg pipes (used in some 1950s-70s homes) collapse. If you built your home before 1990 and it still has its original plumbing, it’s likely nearing or surpassing its expected service life.

Our Commitment to Houston

We’re part of this community. We sponsor local youth sports teams, support Houston-area charities, and employ technicians who live and raise their families here. When hurricanes threaten, we prepare. When flooding occurs, we respond. When the 2021 winter storm devastated our infrastructure, our team worked around the clock to help homeowners recover.  That commitment extends to every service call. We treat your home the way we’d treat our own. We give you honest assessments even when that means talking you out of unnecessary work. We’ve built our reputation one satisfied customer at a time over four decades.

Financing Options for Major Plumbing Projects

Major plumbing work, like whole-home repiping, sewer line replacement, or multiple fixture upgrades, represents a significant investment. We offer financing through approved credit partners with competitive rates and flexible terms. Our office team can explain your options and help you find a payment plan that fits your budget.

How quickly can you respond to plumbing problems in Houston?

For standard service calls, we typically schedule appointments within 24-48 hours, depending on current demand. During extreme weather events or peak seasons, response times may be slightly longer. We provide honest timeframes when you call and update you if anything changes. Our dispatch system sends appointment reminders and real-time arrival notifications so you’re never left wondering when we’ll arrive.

Do you offer free plumbing estimates in Houston?

We provide detailed written estimates for all major plumbing projects before starting work. For diagnostic service calls, there’s a trip charge that applies to any work you approve that day. This covers our technician’s time and expertise in diagnosing your plumbing issue. We explain all costs upfront so you can make informed decisions.

Are your Houston plumbers licensed and insured?

Yes. Every technician on our team holds a valid plumbing license from the state of Texas appropriate to the work they perform. We maintain comprehensive general liability insurance and workers’ compensation coverage. We pull permits when required by Houston building codes and coordinate inspections with local authorities.

What payment methods does John Moore Services accept?

We accept all major credit cards, including Visa, Mastercard, American Express, and Discover. We also accept checks and cash. For larger projects, we offer financing through approved credit partners with various terms available. Our office can review financing options when you’re ready to schedule work.

Do you provide plumbing services for commercial properties?

Absolutely. Our commercial plumbing division serves restaurants, retail stores, office buildings, medical facilities, and multi-family properties throughout Houston. We handle routine maintenance contracts, emergency repairs, tenant improvements, and new construction plumbing. Our commercial team understands the unique requirements of business properties and works to minimize disruption to your operations.

What warranties do you offer for plumbing work?

We warranty our artistry and stand behind the manufacturer’s warranties on the central parts and equipment we install. Specific warranty terms vary by service type; some repairs carry 90-day labor warranties, such as water heater repairs, while central installations like water heaters include more extended written warranties. Offering central installations like water heaters includes more extensive written warranty details before starting your project and honoring them without hassle.

Can you work on plumbing in older Houston homes?

Older Houston homes are one of our specialties. We regularly work on properties built in the 1920s through 1970s throughout Houston’s historic neighborhoods. We understand the challenges of outdated galvanized pipes, insufficient venting, code violations from previous DIY work, and the need to preserve historic details while upgrading functionality. We’ve repiped hundreds of older Houston homes while maintaining their character.

What should I do if I smell natural gas in my Houston home?

Leave your property immediately without turning any electrical switches on or off. Once you’re safely outside, call CenterPoint Energy’s emergency line at 713-659-2111 or 911. Please don’t re-enter your home until authorities confirm it’s safe. After the emergency is resolved, please call us at (713) 853-9881 to inspect your gas lines and make any necessary repairs.

Do you install whole-home water filtration systems?

Yes. We install water softeners, whole-home filtration systems, reverse osmosis units, and point-of-use filters throughout the Houston area. We can test your water quality and recommend treatment solutions for specific issues such as hardness, chlorine taste, or sediment. Water treatment extends the life of your plumbing fixtures, water heater, and appliances while improving the taste and quality of your water.

How often should Houston homeowners have plumbing inspections?

We recommend annual plumbing inspections for homes over 15 years old or for homes that have experienced recurring issues. Houston’s soil conditions and hard water accelerate wear on plumbing systems. Annual inspections catch small problems like minor leaks, developing clogs, and water heater sediment buildup before they become expensive emergencies. For newer homes with no issues, inspections every 2-3 years are usually sufficient.

What’s involved in a slab leak detection and repair in Houston?

Slab leak detection starts with electronic listening equipment that pinpoints the leak location beneath your concrete foundation. We also use pressure testing to confirm the issue. Once located, we discuss repair options: spot repair (accessing the pipe through the slab), rerouting (running new pipes through walls or attic), or epoxy lining (sealing the leak from inside the pipe). The best method depends on your specific situation, and we explain the pros and cons of each approach.

Do you repair or replace sewer lines in Houston?

We both repair and replace sewer lines using traditional excavation or trenchless methods. Video camera inspection shows the condition of your sewer line, whether it has minor damage that can be repaired or extensive deterioration that requires replacement. Trenchless pipe lining or pipe bursting methods minimize yard disruption. Traditional excavation remains the most cost-effective option for many situations. We present all viable options with transparent pricing.

Can you help with low water pressure issues?

Low water pressure can be caused by corroded pipes restricting flow, pressure regulator problems, municipal supply issues, or partially closed shut-off valves. We diagnose the source of your pressure problem and recommend appropriate solutions, whether that’s replacing corroded piping, adjusting or replacing your pressure regulator, or installing a booster pump system.

What’s the difference between tank and tankless water heaters?

Tank water heaters store 40-50 gallons of hot water and maintain it at a set temperature. They’re less expensive to purchase and install but have problems with the pressure regulator and consume more energy. Tankless water heaters heat water on demand as it flows through the unit. They cost more upfront but reduce energy bills, never run out of hot water, and last longer. We help Houston homeowners evaluate which system makes sense based on household size, usage patterns, and budget.

Do you work on gas lines for outdoor kitchens and fire features?

Yes. We install natural gas lines for outdoor kitchens, grills, fire pits, pool heaters, and patio heaters throughout the Houston area. Outdoor gas line installation requires proper sizing, burial depth, and protection from lawn equipment damage. We handle permitting, installation, pressure testing, and inspection coordination to ensure your outdoor gas features operate safely.
