Finally a plumber you can trust. After calling several plumbers I called John at mercy plumbing who was the only person who didn't try to swindle or take advantage of my situation. I had a gas valve leak & every other plumber I called was dishonest, including some listed here that have good reviews. John &his assistant went above and beyond, they took time to explain the problem & gave me choices on how to fix the problem. I am a happy customer. I would recommend mercy plumbing 100% & certified too!!! read more

We woke up to water pouring from a light fixture downstairs. Our upstairs supply line to the toilet broke. The owner of Mercy was out quickly... he was knowledgeable and helped us contact a water damage company also. So confident that it was done right and I don't feel ripped off. read more

Great company...The owner "John" and his son came to my home Saturday morning they were pleasant, professional, affordable and got the job done quick!The prices are good...I was VERY pleased. read more

Water pipe broke outside. Water everywhere running down the street. I shut the main water hose. I called Mercy for help. They we're here within two hours. Bryce did a great job. Highly recommend Mercy. Reasonably priced. read more

Awesome company. Other companies couldn't get to me as quick as I needed. Mercy plumbing actually called and ask if could they could come earlier. Yes please!!!!! They were honest about what needed fixing and worked at lightning speed. I just moved to this house and have saved their info as my go to plumber. Thanks again guys. read more

Nice people. The receptionist, Brianna was very professional and nice. The plumber was very nice. But, the prices he quoted me were very high. They didn't solve my problem, but they charged me $112.50 to look at my water heater, that's with a 10% off coupon. The receptionist told me it would be $29.00 to have a plumber come check it out. He wanted $250.00 to install a kitchen faucet and $1800 to install a water heater. I think this company charges the most allowable by law. A lot of service companies are like this. Shop around before you agree to anything. $250 per hour is pretty high, don't you think? read more

I do not know how their work is but we called them for an estimate (they charge $30 for it). They guy came and gave a absurd quote of more than mid to high 3 digits to fix a couple of leak. About 5 minutes after he left (the guy was at my house for less than 10 minutes to give this absolute absurd quote) the owner called me and sweet talked that he likes to do work in Grand lakes and could get the job done for $50 less and when I asked for a written quote he snickered and laughed as if I had asked for something absurd Long story short ... the parts cost less than $75 and the labour was less than $100 and both the shower and the sink work perfect.... cost me less than 25% of the original quote .... never will use these overpriced not wanting to be professionals. Make sure you shop around before calling them...yes this is a capitalist society and yes businesses make profit but charging 3-4 times more than market is what Mercy plumbing does... so shop around read more

John and his assistant Jonah saved the day at my house. My bathroom was flooded from a leaked valve. They fixed the issue along with installing a new commode. John was very kind and honest. His prices are very affordable. I highly recommend Mercy Plumbing! Thank you John!! read more

John, the owner was amazing. He helped me with a very difficult problem and gave me a reasonable price quote. He was the only one of three plumbers who was completely correct about the issues and knew exactly what he was talking about. He was honest and they completed the job quickly even through poor weather. Of the several plumbers I had come, he seemed the most honest and reliable and turned out to be just that. Would highly recommend! read more

The plumber was late and rude. The day before my appointment, the phone receptionist scheduled my appointment between 7 am and 8 am. The plumber arrived at about 8:10 am. I had gone off to get ready for work because they did not arrive during the specified time window. They arrived when I was in the shower. When I came out at about 8:25, the guy had the nerve to tell me they were waiting on me, and then he proceeded to argue with me that they do not schedule appointments for 7-8 am (he said their timeslots start at 8-9 am). After they left, my wife told me the guy had been giving her a hard time the whole time I was getting ready. read more

I had an experience with a plumber that I felt less than satisfied about so I called Mercy on Saturday morning at 9 and they were at my house in Sugar Land by 1. The owner was professional and honest and cared about my comfort level doing certain things. He got my hot water heating working again in no time and was practical and knowledgeable when explaining the issues and possible solutions. They might be a bit on the expensive side (but I don't know for sure) but I don't mind paying a bit more for satisfaction and integrity. Will absolutely use again. read more

We were in a jam and on a very tight shedule to address a plumbing issue on a Saturday; prompt and proffessional service. Outstanding work; will be reffering Mercy Pluming to friends and colleagues. Quailty of work is synonymous with the weekend rates and cost; will be a return client. read more

He can do the easy stuff, and it will cost $250, regardless. I had him over to try and diagnose a moisture issue and he could not figure it out. Another plumber did quite quickly and it was a simple fixture leak. He "shoots from the hip". Not a good listener, and somewhat rude. Would not recommend. read more

Called them out to look at my gas line in my kitchen that was poking out of the wall. It was making my stove poke out 6 inches from the wall and driving me crazy. The owner came out to my house and gave me two options on how he could fix it and then had the job done within 20 minutes and even cleaned up after his self. I would definitely recommend this company for your plumbing needs! Thanks Mercy Plumbing :) read more

Very pleased with the service we received from John & Jona. They went above and beyond to troubleshoot our problem and got us up and running in a timely manner. They were very respectful of our property and left everything nice & neat. Can't say enough about these guys and the service they provide! read more

AVOID AVOID AVOID - RUDE The owner is rude. Plumber charged $250 for a sink that was not fixed and would not warranty his work. Very unprofessional yells at customer despite me being patient with him trying to explain a problem with his plumber. I won't use again. read more

I personally tried to change out my shower fixture and broke the valve. I needed the water back on ASAP because I have painters in the house and moving in within the next few days. One company said I needed to tear down the shower wall to fix it. I called Mercy Plumbing and they were able to fix it first thing in the morning before the painters showed up! Without tearing down any shower walls! He even went around the house to make sure nothing else was having issues and fixed a clogged drain at no cost. Would highly recommend this company who is looking for a reliable plumber! read more

I had Mercy Plumbing come out and help me with a gas leak at my gas meter. I am giving them two stars because they did finish the job they said they would (pressure test and capping of leaking pipe) but not without troubles. The short version is we were stood up twice (one of which was a no call/no show) by the technician, no return calls from management, and overcharged up front to lock us in from shopping around. Overall not a good experience. Do yourself a favor and keep searchinge. read more

John and nephew took care of my backed up toilet. I could tell that he's a good, honest man by his firm handshake and greeting. I will most likely call him back for other plumbing needs. read more

Called this morning due to my sink backing up, regardless of Liquid Plumber and snaking it. Service was within 5 hours, the plumber was over for about 90 minutes, tested twice after resolving issue to ensure it was fixed, cleaned up, was very polite. We are very pleased with the service we received. read more

We are out of state property owners with a property in Houston. Our tenant notified us on a Saturday about an emergency plumbing issue. After contacting several companies, none could do the work until Monday. This would have caused our tenant to be inconvenienced the whole weekend. Enter John. He arrived on Sunday and gave us an estimate. Once he began the repairs, however, he found an additional problem with the toilet. The toilet is a specialty item he couldn't get until Monday. So, John picked it up and finished the job Monday. Mind you, he did all of this for his original estimate. John's integrity and attention to detail likely saved us a lot of money in the long run. I highly recommend him and will use him in the future. read more

I had a major plumbing problem at my house which required all new sewage pipe to be installed from my home to the street. I had one prior estimate before contacting Mercy plumbing. Mercy was able to complete the job for LESS THAN half of my 1st estimate. They even worked all the way through a Holiday weekend (Saturday & Sunday) in order to ensure my situation was fixed quickly. They did an outstanding job for a very fair price. My only complaint is that it took a couple of phone calls and SEVERAL days for me to get an invoice/work order for my record keeping. read more

I'm a relatively new homeowner, so I didn't know how to shut the water off to the house easily (it was a lever or a crank right outside the house that doesn't require too much force). So, when the water valve under my sink broke (it was cheap and wore out, apparently), hot water was spewing under my sink for a good 10 minutes. My wife threw all our mats in the cupboard under the sink to suck up the water, while I tried to find how to turn it off. It was crazy. Finally, I turned off the water at the main meter, which was ridiculously difficult. I had to use a hammer. Anyway, called Mercy Plumbing after. John from Mercy Plumbing who's a friendly guy came over pretty quick and identified the leak as a worn out valve that needed replacement and replaced it immediately. The best thing with John from Mercy Plumbing and I bet probably from other plumbers working with him, is that he's upfront with what it would cost (fair pricing) and keeps his word. If you're anxious and you start to think, maybe I should just change every valve in the house, he's honest in saying that's not necessary. John also educated me how to turn the water off quickly next time round and advised me to check for possible mold that might form. I would definitely call Mercy Plumbing again for my plumbing needs. read more

Late in the afternoon, John and his assistant Tony turned detective to discover the cause of water damage. Luckily, the walls that needed to be cut were in a closet. After determining the cause to be a pipe coming up through the concrete slab, John clearly explained the procedure and possible complications. John and Tony arrived on time the next morning. We got lucky again when it was learned that the leaky pipe only supplied one downstairs sink. Once the faulty pipe was capped, a T-joint in an upstairs line was created and a PEX pipe was dropped down to supply the downstairs sink. No other walls or floors needed to be damaged in order to complete the work. The job was finished after 4 1/2 hours, which included a run to the supply house. Plus, he was here about 1 1/2 hours the evening before. They vacuumed the area and left everything cleaned up. John charges a flat rate, but was not able to predict how extensive the job would be. He quoted a price for finding the leak and capping it. Then, he once knew what would be required in order to supply the sink, he gave me another ballpark figure to which I agreed. In the end, the bottom line was less than he quoted. Although it was not itemized, I feel that this charge was reasonable given the knowledge, skill, and creative solution that was required. I also feel that another plumber could have easily gone a different and more extensive and expensive way. I highly recommend this plumber for your home needs. read more

I am new to the Katy area and used Yelp reviews to choose Mercy Plumbing to do some (what seemed to be) fairly simple repairs. Breanna in the office was very friendly and helpful and John, the owner, told us how experienced he is (several times) so we hoped we had found a good service. The pricing seemed quite high but we moved forward hoping for a professional repair. The price was over $1500 for about 2 hours work. The invoice was extremely vague and unclear so I asked for a breakdown, but never got it. Two days after they were here, the toilet in my master bath started doing the same thing that caused me to call a plumber initially. Everyone was on vacation for over a week so we just didn't use that toilet until they got back. When they came back out, they said some part inside the toilet was installed backwards and that's why the toilet didn't work properly. They charged us another $250 to make this repair which it seems they should have found the first time. A few hours later we found that the toilet was leaking. They came back and repaired it the next day but we told them not to come back if there would be any additional charge. The toilet still doesn't work properly (the handle which they replaced sticks in the downward position when flushed) but we are just living with it and will contact a different plumber at a later date. The whole experience was very frustrating. read more

John was great. He was able to make some time for me the same day I called for an appointment, was super friendly, and was able to install some new valves for my washer and hot water heater. I know who I'll be calling next time I need some plumbing work done. read more

Had a water pipe burst in the wall this past Saturday, 3/16 around 3pm. Called Mercy and left message. Called another company said they could come out but didn't know when. Had two calls in front of mine. Within 15 minutes of leaving message with Mercy, Esai called and said he just finished a job and could head my way. I called back other company and cancelled. Mercy was here in about 15 minutes and said depending on location and type of plumbing involved would price would be within a quoted range. After locating leak, I was given a price within the quoted range toward the lower end. Esai was here about 2 hours. He was very nice, professional and had some good advice. He cut the hole in the wall,sheet rock,just big enough to do the job. I was able to find an spring loaded access panel at HmDpt to cover the hole. Thanks for the tip! It fit perfectly. To date water is where it's supposed to be, in the pipes, and we are very satisfied with Mercy Plumbing and Esai. I will not hesitate call if needed for another job. read more

Wonderful experience with John (owner) and Jonah (apprentice ) at Mercy Plumbing! Very professional, fair, and efficient. They addressed the main reason for my call and corrected an additional problem that I had been told by three previous plumbers "couldn't be fixed/was a result of the design of the home".....at NO additional charge! Very thankful for their service and will call on Mercy in the future. read more

If you need a plumber who is smart enough to diagnose your plumbing problem accurately and honest enough to not rip you off during the most vulnerable time, John Mercy is the guy you call. John and his nephew came out to my house after the previous plumbing company told me I had a leak and would take at least $3000 to fix (and somehow I had a gut feeling not to trust them), he diagnosed no leak but fixed an unstable toilet for me which was MUCH cheaper. Later I had a plumbing emergency in my dental office and he came out during the time when he should be having family dinner and diagnosed our plumbing problem. He saved us from having to shut down the office the next day. He's a rare gem in his profession and it shows as he's getting all the five star reviews on Yelp! read more

I have finally found a trustworthy plumber, one that doesn't try to up-sell you on needless aspects of the repair. John is honest and fair, and give you the straight skinny on the job at hand. HIGHLY RECOMMENDED. read more

Same day service! Great job! When the water line to my house broke I was stuck without any water. Mercy Plumbing was the only service I called who didn't ask me to wait a few days and was able to have someone to my house in a couple hours. My water was back on within 2 hours of their arrival and the price was definitely affordable. I would definitely recommend Mercy Plumbing. read more

What a relief to find a plumber who is fair and timely. I am pleased with their service and price.

John was great. Our hot water heater was broken. He came and assessed, got the part and fixed even though it was 7:00 pm. It was great to have hot water again. Thank you Mercury Plumbing! read more

I woke up to a broken pipe on a cold,rainy Sunday morning. I called John and explained where the breakage was then we discussed the fees which were fair and he was at my residence in no time. He was very professional and good at what he did. He had the pipe fixed and my water back on in no time while also taking the liberty of putting on installion since it was the freezing time of season with no extra charge . I will use him in any future problems and would recommend him to anyone. read more

I called John this morning at 7am; he was very professional on the phone and during the site visit. We had a main clog in our sewage line, which he unclogged. He also verified we had no roots running through or main line from the house to the city manhole using his fiber optic cable. He arrived to house within an hour of calling, and did not charge me an extra fee due to calling him early in the morning. I appreciate the work John and his co-worker did; I'd easily call them again for any plumbing problems. read more

I had a plumbing leak in my attic and called John after another plumbing company never returned my calls. John fit me in by the end of the day and fixed my leak within 45 minutes. Pricing was reasonable and John was a pleasure to deal with. I would highly recommend Mercy Plumbing and will use John for my future needs! read more

My husband and I have lived in our home for 30 years, and in all that time have relied on one of the Big Name Plumbing companies. This time, when our 6-year old water heater nearly leaked through a ceiling, we decided to turn to Mercy Plumbing, and it was life changing. We called John at 7 AM (so sorry!) on a Saturday morning, and he was at our front door with a replacement water heater by 11. He had called us to let us know that simply replacing the control box would do the job, but knowing that this model's boxes were prone to failure, we opted for a new brand and new machine. John is knowledgeable, energetic and swift. In two hours we had a faulty machine out of our home, plus a leaking exterior faucet that two different Big Name plumbers told us was impossible to repair working like new. We will never go anywhere else, and I only regret not making the switch sooner. This is the best plumbing service in town. Sincerely, Kathleen McKeague Travis Posey Missouri City Sent from my iPad read more

John with Mercy Plumbing came to my home to give me a estimate to repipe my whole house . He was by far the best price and was very patient and answered every question my husband and I had. We were very pleased with his clean and professional work ethics . He covered all furniture and flooring during the job, I never felt inconvenienced at all during the time he was here and when he would leave for the day we always have running water. I would definitely use Mercy Plumbing again in the future an refer him to all of our friends and family. read more

Mercy Plumbing - Plumbing Near Me - Katy, Texas

My water heater stopped working a bit over a month ago. I called Mercy and John came out and assessed the damage -- I knew the heater was old (10+ years) so it wasn't surprising to me when he said the unit would need to be replaced. He was able to get a suitable replacement and had it installed the next day! The work was done well, great manners, were careful not to bang anything around in my home and not track dirt anywhere (he even vacuumed after!). When the unit malfunctioned a month and a half later (bad part -- not John's fault) he came out immediately and fixed the issue. Very good company, great service, will use them in the future for my plumbing! :) read more

John & his associate came out to inspect and repair my water heater. Although I had some standing water in the emergency pan he was able to quickly find out that the water came from the roof and not the water heater itself. He relit the pilot light, did some service work and was finished in about 15 minutes. He didn't try and take advantage of me when I thought the situation was much worse. He also fixed a couple of my sink poppers that weren't working at no charge. He is an honest guy who also was kind enough to give some goodwill. His prices were much lower than others, but I would have been willing to pay the same as other large companies quotes to have him perform the service work. I highly recommend his company and plan to use him for all plumbing issues. read more
