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!

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

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!

Commercial Plumbing Service in Allen, TX for Businesses
Commercial plumbing demands a different level of preparedness than residential work; the fixture counts are higher, the consequences of downtime are immediate, and the code requirements are more involved. BlackRock Plumbing Company serves Allen businesses with the full scope of commercial plumbing services those properties require. Restaurants, medical offices, retail centers, and multi-tenant buildings all have distinct plumbing needs, and our team has the experience to handle them. A drain backup or water heater failure during business hours is not a next-day problem, and our around-the-clock availability reflects that reality. We install and repair commercial gas lines, service high-demand water heating systems, and perform sewer line camera inspections for property managers who need accurate underground infrastructure assessments. Hydro jetting is a core maintenance service for commercial kitchens in Allen, where grease accumulation in drain lines builds up faster than standard cleaning methods can address. Leak detection protects commercial interiors from the hidden water damage that wall and slab leaks cause when they go unnoticed for extended periods. We also handle full repiping for older Allen commercial buildings where supply line deterioration is creating pressure or water quality problems throughout the property. Every recommendation we make is grounded in what the system actually needs, not what generates the largest service ticket. Allen businesses that need a reliable commercial plumbing contractor will find that in BlackRock Plumbing Company.

Plumbing Service in Allen, TX
Burst pipes are among the most damaging plumbing failures a homeowner can face, and they require fast action to limit water intrusion into walls, floors, and structural framing. BlackRock Plumbing Company responds to burst pipe calls in Allen at any hour, stopping the flow first and completing a code-compliant repair as quickly as conditions allow. Freeze events are the most common trigger for burst pipes in North Texas, particularly in supply lines running through exterior walls or unconditioned attic spaces. Drain cleaning is a service that prevents the gradual buildup of grease, soap residue, hair, and mineral deposits from becoming a full blockage inside residential drain lines. Most homeowners do not notice a drain slowing down until flow has already been significantly restricted, by which point the clog is well established inside the pipe. Our technicians clear drains completely and check downstream for secondary buildup that would cause the same problem to return shortly after the initial cleaning. Addressing the full length of the drain line rather than just the nearest accessible clog delivers a longer-lasting result. BlackRock Plumbing Company treats drain cleaning as a thorough service, not a quick fix.
Faucets fail in gradual ways that are easy to ignore until the drip becomes constant or the leak migrates behind the wall. Worn cartridges, degraded O-rings, and corroded valve seats are the most common internal failure points, and our technicians carry the components needed to address all of them in a single visit. A faucet dripping at one drop per second wastes roughly 3,000 gallons of water per year, making prompt repair a practical financial decision beyond just the annoyance factor. Faucet installation is a service we perform for Allen homeowners upgrading fixtures during a remodel or replacing a unit that has corroded beyond economical repair. Every installation includes a full pressure test at both supply connections before the job is considered complete. Garbage disposal repair covers the most common failure modes: grinding jams from hard food items, leaks at the mounting collar, and motor failures that leave the unit humming but not spinning. We assess the disposal’s overall condition when called out for any repair, letting the homeowner know whether the unit is worth servicing or whether replacement makes more sense given its age and condition. Replacement units are installed with attention to drain connection sealing, mounting assembly security, and proper electrical connection before testing begins.
Gas line installation requires correct pipe sizing, approved materials, and a licensed plumber at every stage of the project. We install gas supply lines for ranges, dryers, water heaters, fireplaces, outdoor cooking stations, and whole-home generators, calculating the correct pipe diameter for each appliance’s BTU demand before any work begins. Pressure testing is the final verification step on every gas line we install, confirming zero leaks at every fitting and joint before the line goes into service. Repair calls for gas leaks are treated as urgent regardless of the apparent size of the leak; our technicians arrive prepared to locate the source with detection equipment and make a permanent repair. Hydro jetting delivers a level of drain line cleaning that a mechanical snake cannot replicate, scouring the full interior circumference of the pipe rather than simply punching through the center of a blockage. This method is particularly effective for sewer lines with long-standing grease accumulation or root intrusion that has partially colonized the pipe interior. Allen properties with mature landscaping near sewer lines are frequent candidates for hydro jetting combined with a camera inspection to confirm the line is fully clear after the service. The results are measurable immediately in restored drain speed and reduced backup frequency.
Leak detection locates water losses that have no visible surface sign, including supply line failures beneath slab foundations, leaks inside wall cavities, and pressurized line failures under yard surfaces that inflate water bills without producing any wet area inside the home. Electronic acoustic equipment and pressure isolation testing allow our team to identify the precise location of a leak before any concrete or drywall is opened, which directly reduces the cost and scope of the repair. Slab leaks are a documented problem in North Texas homes, where ground movement applies cyclical stress to pipes embedded in or passing below the foundation. Piping and repiping address homes where the supply system has deteriorated to the point where ongoing repairs are no longer the right financial decision. We evaluate the full system before recommending a repipe, and we plan the project to keep the household without water for the shortest time possible during the work. Sewer line inspection with camera equipment provides documentation of buried pipe conditions without any excavation, capturing footage of root intrusion, pipe sag, cracks, and offset joints that are impossible to assess from the surface. Homebuyers in Allen frequently request camera inspections as part of due diligence on older properties, and we provide a clear assessment of what the footage shows.
Sewer line installation covers new municipal connections, full replacements for structurally failed lines, and capacity upgrades where fixture additions exceed the existing pipe’s diameter. We install at the correct grade for continuous gravity flow and confirm the connection to the city main before the trench is closed. Sewer line repair targets specific damage zones rather than defaulting to full line replacement; localized root intrusion, isolated cracks, and single offset joints are all candidates for spot repair that costs the homeowner significantly less than pulling and replacing the full line. Sump pump installation protects properties with below-grade spaces or drainage patterns that collect surface water near the foundation during heavy rainfall events. We size the pump to the pit volume and drainage area, route the discharge line well away from the structure, and test the float switch before leaving the property. Sump pump repair diagnoses the specific failure mode, whether that is a burned motor, a stuck float arm, or a blocked discharge line, and restores function before the next weather event creates a real problem. A sump pump that fails quietly during a dry period gives no warning until water is already on the floor of the protected space.
Tankless water heaters solve two problems that come with traditional storage tank units: the limited hot water supply that runs out during back-to-back showers, and the standby energy cost of keeping a large tank heated continuously when demand is low. These units heat water on demand as it flows through the heat exchanger, delivering continuous hot water as long as the flow rate stays within the unit’s rated capacity. BlackRock Plumbing Company sizes every tankless installation correctly for the home’s peak simultaneous demand before selecting the unit, ensuring the performance matches real-world household use. Toilet installation involves more precision than it appears from the outside; a level flange, an evenly compressed wax seal, and a pressure-tested supply connection are all required before the bathroom goes back into service. We install all standard residential toilet configurations and test every flush and fill cycle before signing off on the job. Toilet repair addresses running fill valves, worn flappers, cracked flush valves, and wax seal failures at the base, with each problem diagnosed specifically rather than replaced by default. A running toilet can add thousands of gallons to a monthly water bill depending on the severity of the internal valve failure, making a timely repair worth scheduling promptly.
Water filtration systems improve tap water quality by removing the chlorine, sediment, and dissolved minerals that pass through municipal treatment into the residential supply. Whole-home systems treat water at the point of entry, protecting every fixture, appliance, and supply fitting in the house from the scale buildup that hard water accelerates. Under-sink reverse osmosis systems provide a higher filtration level specifically for drinking and cooking water, removing contaminants that entry-point systems are not designed to capture. BlackRock Plumbing Company installs both system types and integrates them cleanly with existing supply plumbing. Water heater inspection is a preventive service that extends equipment life and catches developing problems before they result in a complete failure; we flush sediment, check the anode rod, test the pressure relief valve, and inspect all fittings during every visit. Water heater installation covers both tank-style and tankless units, with each installation connected correctly to the fuel source, water supply, and appropriate venting or exhaust system. Water heater repair in Allen addresses pilot light failures, thermostat problems, heating element burnout, and leaking tank connections before they escalate into a full unit failure. Supply lines throughout the home represent the final link in the water delivery system, and BlackRock Plumbing Company keeps them in reliable working condition with inspection, repair, and full replacement available on every service call.
