BlackRock Plumbing Company serves Lavon, TX with licensed, insured plumbing services covering water heater repair, sewer line installation, gas line work, drain cleaning, leak detection, repiping, and the full scope of residential and commercial plumbing needs.
Reliable Plumbing in Lavon, TX
Lavon, TX sits at an interesting point in its development, still carrying the character of a small lakeside community while absorbing the residential growth pressing outward from the broader Collin County metro area. That combination produces a diverse mix of property ages and plumbing system conditions that a good plumber needs to be ready for on any given call. BlackRock Plumbing Company serves Lavon with the technical range to handle both a decades-old supply system and a newly built home where builder-grade components are starting to show their limitations. Owner John Walsh has never run a commission-based operation, and that decision shapes everything about how the company operates; technicians diagnose honestly and recommend only what the plumbing actually requires. Getting a second opinion on a plumbing recommendation should never be necessary when the first plumber is working without a financial incentive to expand the scope. Our Princeton, TX location puts Lavon comfortably within our service area, and we are available at every hour for emergency calls that cannot wait for a morning appointment. Every truck arrives stocked for the job, and we communicate clearly with homeowners throughout the process so there are no surprises on the invoice. Lavon residents deserve a plumber who is straight with them from the first phone call to the moment the truck leaves the driveway. That is exactly the standard BlackRock Plumbing Company holds itself to on every job in this community.
John has done great work for us on large shower remodel and kitchen faucet and valve replacement. I would highly recommend BlackRock plumbing.
Plumbing repairs were completed as scheduled. Work was completed to satisfactory level.
I had a great experience with John from BlackRock Plumbing. He came out to fix some under-the-kitchen-sink pipe issues and was professional, knowledgeable, and efficient from start to finish. He quickly identified the problem, explained everything clearly, and had it repaired without any hassle. The work was clean, solid, and fairly priced. It’s hard to find someone you can trust with plumbing repairs, but I’d absolutely call him again and recommend him to anyone needing reliable service! Thank you John and so glad to have a great company in Princeton!
John got our issue taken care of in under 15 mins. He was professional and courteous. Thank you so much for taking care of our issue!
John was great. He came out to look at an outdoor fireplace so I could close on this house. He was responsive and provided service and updates quickly. He did a great job and we are good to close. Thank you John!!
John was amazing, he was a true professional and he knew his job. I told him what I thought the issue was and he immediately solved the problem. John was great, very personable. I highly recommend BlackRock Plumbing. A real five star company!!!
John was great, always timely, does amazing work, great prices and was able to fix the problem in my bathtub same day. 10/10 would recommend!
I recently used Blackrock Plumbing and couldn’t be more impressed. From the first call to the completed repair, their team was professional, punctual, and knowledgeable. They clearly explained the issue, provided a fair estimate, and completed the work efficiently. Everything was left clean and working perfectly. It’s rare to find a company that combines quality workmanship with excellent customer service. I highly recommend Blackrock Plumbing to anyone looking for reliable and honest plumbers.
John with BlackRock plumbing showed up after hours to repair a leak that another plumber couldn’t even locate. His response time was great, and his team did a fantastic job. 100% recommend BlackRock Plumbing!!
Big thank you to these plumbers who showed up after hours to repair a leak we could not locate. The after hour fee was very reasonable for what the work entailed!
Wouldn’t work with anyone else - BlackRock provides timely service, in a professional manner, while being reasonably priced & are transparent with their customers from start-to-finish. Give them a call for ANY of your plumbing needs; you’ll be in good hands.
My experience with BlackRock I have to say was one of, if not the best, plumbing jobs we have had done. John was extremely knowledgeable and made it easy for us to understand from start to finish. Although our issue was an unfortunate one... We were so relieved to have the fix be as seamless as it was. If I could do 6 stars I would..
We’ve used John Walsh at Blackrock Plumbing Co. exclusively for about two years, including the installation of a new water heater. He’s been consistently reliable and punctual, fair, and does very high-quality work. He communicates clearly, shows up when he says he will, and I trust his recommendations. If you want a plumber you can count on, John is the real deal. We would be happy to share our great experiences with anyone who needs a personal reference!
Great, prompt service. We called John due to plumbing issues we were having at our business. He came out same day, quickly identified the problem and quickly remedied the issue without any effect to our business operations. A true professional that I would highly recommend for any plumbing needs in Collin county.
John was awesome and knowledgeable about his trade! He’s my plumber forever now! Thanks BNI…..
Out of the quotes I received for my front lawn leak repair, John was significantly lower. I was happy to hire him to do the repair, and he and his team showed up early the next day and finished repair within a couple of hours. Also, he didn't try to upsell products but instead fixed a leak with my water heater for free. And when it is time to change it, I will give him a call, he has my business from now on. [His price for water heater replacement was also lower]. I highly recommend John for your repair, you won't regret it. Get several quotes and you will see John is your best bet. And what he quote you is what you will pay, no surprises.
Today is January 1st and I was not expecting John to be able to come and help us. But he did. He cares about his customers! Plus his work was excellent!
We had a very stressful situation late at night on December 23rd when water started leaking from under our kitchen island. With Christmas Eve approaching, we were worried no one would be able to help and that this would turn into a major repair. We contacted John from BlackRock Plumbing Company late that night, and he came first thing the next morning, extremely punctual and reliable. He was polite, professional, and worked cleanly and carefully. It was immediately clear that he knew exactly what he was doing. He walked us through the entire process, explained everything clearly, and you could tell right away that he would never take advantage of anyone. John fixed our situation quickly and at a fair price, which was such a relief. We are absolutely saving his contact for any future plumbing needs. Thank you so much, John, for truly saving our Christmas Eve!
They were amazing, came out same day and diagnosed the problem immediately. Found a way to get us back with hot water quickly while waiting for parts. Would highly recommend them and will use them again for any plumbing issues.
John is an experienced plumber, he knows what he is doing, a honesty and passionate guy who is worth dealing with! Highly recommend

Thanks John is fantastic! He arrived at 7am sharp as promised on a Saturday. He was the only one who could come out, as other companies had a wait time till Monday to Wednesday the next week.

Excellent service! Came on short notice and was very kind. Would highly recommend this company to anyone with plumbing issues.
We were pouring a new concrete driveway and needed to excavate the old one. We discovered that our water supply pipe was embedded in our 80 year old driveway when the pipe was pulled up along with the driveway. The broken pipes and leaking water was going to stop our 12 man team from working on our project. John of BlackRock Plumbing was able to arrive with in an hour to quickly assess the situation. He went out to acquire the parts he needed and very capably fixed the broken pipes. Our project was back on track. Thank you John for saving the day!
John was super knowledgeable and same day service was exceptional. Highly recommended.

During some home renovations, I broke water pipe and had water spraying everywhere. I called John at BlackRock and he was out in 20 minutes! On a Saturday evening no less. Prices were very reasonable and he got the work done quickly, cleanly and in a very professional manner. I honestly couldn't have had a better experience, BlackRock saved my weekend.
I had such a great experience with this plumber. From the moment he arrived, he was polite, respectful, and very kind. He took the time to explain what needed to be done in a way that was easy to understand, and I never once felt rushed or like he was just trying to get in and out. He worked carefully, made sure everything was fixed properly, and even checked back over his work to be sure it was perfect! I won’t hesitate to call him again or recommend him to friends and family.
I'm so glad I called him. Exceptionally nice young man. On time, fixed the leak and his services were affordable, especially for an old lady on a fixed income.

John and BlackRock Plumbing is the best! Highly recommend their services. We used him for 3 issues that we were having with our shower, our sinks, and our outside drain. By sending him a few pictures and brief descriptions, he arrived on time and prepared and repaired all our issues in an efficient manner, and at a fair price. Hoping we don't have any future plumbing issues, but if we do, we will be using BlackRock. We are also planning to use their services on a Commercial project in Princeton later this year. Thank you John.

BlackRock Plumbing offers reliable plumbing services for homeowners in McKinney, TX and nearby communities. Our licensed plumbers take care of everything from everyday repairs to full plumbing system installations. Explore the plumbing services we provide below:
Commercial Plumbing Service in Lavon, TX for Businesses
The commercial properties serving Lavon, TX range from small neighborhood businesses to larger operations that support the community’s growing residential population, and all of them share a common need for plumbing that functions reliably without constant intervention. BlackRock Plumbing Company provides commercial plumbing in Lavon with a practical, no-nonsense approach that keeps the focus on solving problems rather than generating repeat service calls. Commercial plumbing failures create downstream consequences that residential failures do not; a non-functional restroom closes a dining room, a water heater failure shuts down a commercial kitchen, and a gas line issue stops operations entirely until the repair is complete. Our 24/7 availability ensures Lavon business owners have a licensed plumber to call the moment a problem surfaces, regardless of the day or hour. We install and service commercial gas lines, perform sewer line camera inspections for property managers who need documented infrastructure assessments, and use hydro jetting to maintain commercial drain systems that accumulate grease and scale faster than residential lines. Leak detection protects commercial interiors from water damage that develops inside walls and above ceilings without triggering any visible alarm until the damage is already significant. Multi-fixture restroom installations, commercial water heater systems, and full building repiping for older Lavon commercial properties are all within our service scope. We assess commercial systems on their actual condition and recommend accordingly, with no inflation of scope and no unnecessary return visits built into the service plan. BlackRock Plumbing Company gives Lavon businesses a commercial plumbing contractor they can call consistently and trust completely.

BlackRock Plumbing proudly provides plumbing services not only in Lavon, TX but throughout the surrounding communities within our service area. See our full service area below:
Plumbing Service in Lavon, TX
A plumbing system is only as reliable as its weakest component, and in homes that have never had a full system evaluation, weak components tend to announce themselves at the worst possible moments. BlackRock Plumbing Company performs thorough assessments during service calls in Lavon rather than addressing only the immediate complaint and leaving undiscovered problems behind for the next technician to find. Burst pipe repair is a core emergency service we provide throughout Lavon at any hour; when a line fails, stopping the water flow quickly is the first priority, followed by a complete evaluation of the affected run to identify any additional vulnerability in the surrounding pipe. Freeze events in North Texas create burst pipe risk in supply lines that are not adequately protected from overnight temperature drops, and certain installation patterns common in tract construction leave lines more exposed than homeowners realize. Drain cleaning in Lavon addresses the steady accumulation inside residential drain lines that develops from routine use and is easy to ignore until a full blockage forces the issue. The slow drain that has been present for months before a homeowner calls is typically the result of buildup that has been developing much longer, and clearing it requires working the full drain run rather than just the nearest trap. Recurring clogs in the same location are a signal that the problem extends beyond the immediate blockage point, and our technicians investigate accordingly rather than applying the same quick fix repeatedly. BlackRock Plumbing Company resolves drain problems completely rather than managing them temporarily.
Faucet failures in a home tend to start small and grow; a cartridge that drips once every few seconds becomes a steady stream within months, and a supply connection that seeps slightly under a sink will eventually saturate the cabinet floor and the wall behind it. Identifying all of the failure points during a single service visit rather than addressing only what is visible at the moment is what separates a thorough plumbing call from a temporary fix. Our technicians inspect the fixture body, both supply connections, and the angle stops beneath the sink during every faucet service call, addressing everything that is worn or leaking before the job is closed. Faucet installation is a service we perform with attention to the supply side as well as the fixture itself; a new faucet installed on a corroded angle stop or an undersized supply tube is going to cause problems regardless of the quality of the new fixture. We evaluate and replace those supporting components when they need it, ensuring the new installation performs as expected from day one. Garbage disposal service in Lavon covers repair and replacement with equal capability; we carry the parts to address jams, housing leaks, and motor failures, and we stock replacement units for situations where the existing disposal has reached the end of its useful service life. Installation of a replacement unit is completed with the drain connection sealed, the mounting assembly locked, and the unit tested under running water before the cabinet is closed up and the job is signed off.
