Called these people for an estimate to repair/replace leaky copper pipes in the basement that were leaking, on top of the Hot Water heater. The guy came out, don't want to name the plumber, sent me an estimate literally 5 minutes after leaving the house. The estimate was for almost $5000 to replace the hot water heater and another $4500+ to repair/replace the leaky pipes for a total of almost $9500. Ridiculously laughable. I was able to get the job done for $1200 total by a licensed independent plumber. I didn't need the HW heater to be replaced. They just had to remove some HVAC ductwork to get to the leaky pipes, which they put everything back after replacing pipes. Do Not use Mallick I would consider them to be untrustworthy, and total rip off. Always get at least 3 estimates just make sure they are licensed. I still ended paying $99 for Mallick because they have a policy you pay $99 for estimate but gets added to the total if you get the work done. Again, ripoff. I also got an estimate from FH Furr that was significantly lower than Mallick but they were unwilling to remove ducts that they didn't install. Another ridiculous policy by another large plumbing company even though their plumber said they would have to involve the HVAC department. Maybe their plumbers don't know company policy. These guys didn't charge for an estimate. My recommendation is DO NOT use Mallick and even DO NOT use FH Furr. read more

I was a customer of theirs until they tried to rip me off by charging almost $900 for a hose bib replacement. That being said there are plenty of other plumbing companies around. read more

Replaced a household hot water tank heater with modern efficient heat pump, added constant water pressure well water system, replace kitchen sink drain flange. Professional, clean, and polite are words I'd use to describe Mallick plumbing service for this job. The crew, Brandon and Chris Mallick, worked a very long day to ensure we had hot water before leaving. Thanks! Kristen, who secretly seems to run the entire operation, was pleasant and professional in handling our communications (i.e. scheduling and status) with the office. Thanks! As for value, we did not seek a second estimate. Yet, I believe that if you want a hot water system on a well job done right the first time, Mallick is a reliable choice. Yes, recommend them. read more

I paid Mallick $1,654.33 for two technicians and approximately two hours of labor to replace a well-pump controller. I was also charged $2,485.50 for a Goulds Aquavar Solo 1AS15 controller, which I found listed on Amazon for $1,487.46. It then took two weeks of repeated phone calls to receive a detailed invoice, which I needed to file an insurance claim. I was initially told that Mallick does not provide detailed invoices because it uses flat-rate pricing. My insurance company's inspector estimated the reasonable cost at $190 for labor plus $2,061.59 for the equipment. Based on the large difference between those figures and what I was charged, I felt the pricing was excessive and the experience was frustrating. I recommend requesting a fully itemized written estimate before authorizing any work. read more

I am living at my parents house and the company is refusing to acknowledge that their original installation of new valves in a 1940's shower are the direct cause of water hammer. They have been told that the tub valves do not exhibit this problem, yet they have offered to come back twice for two $99 service calls where they did not examine the valves or type of valves but measured the water pressure at 80psi and said there is your problem and if that does not fix it we may have to do more. The resolution requested to make this right is refund two $99 service calls and replace the stems and seats at no cost with the correct rubber compression type instead of ceramic. They offered to give us photos of the original valves, and pricing for the PRV was requested to be two options, instead they offered an option known to be cost prohibitive for $2700 for a PRV and also stated the house required double backflow valves without examining the meter base outside. read more

I had a great experience with Mallick Plumbing. Jose and Kyle replaced a toilet for us today and were a pleasure to work with. They were very respectful of our home, wearing shoe covers and making sure they didn't leave a mess behind. The installation looks perfect and works great. Thank you, Jose and Kyle, for the professional and friendly service! Also wanted to give a shout out to Kristen and Sarah for helping with coordination / documentation! read more

I'd like to commend the services provided by Jeremy T at my home in Washington, D.C. on June 19, 2026. Jeremy was courteous and professional. In addition to conducting an annual plumbing inspection, Jeremy installed a Flo by Moen, replaced an existing shut-off valve for my unit's main water line, and added a new drain line for my dishwasher. I've worked with Jeremy for home maintenance on several previous occasions and would gladly work with him again. I continue to appreciate Mallick's customer service and expertise! read more

Well, this was disappointing. My shower was leaking due to a faulty cartridge. The very kind and professional plumber showed up, on time. He looked at it and then quoted me a cost of $600 to repair. Seriously, this is a $70 part at Home Depot, and he would need maybe a half hour of time to do the fix. I don't mind companies making money, but this is highway robbery and so over inflated. When I was in a house, I only used Leahy Plumbing and they never took advantage. Their prices are reasonable. Unfortunately, they won't service a condo. So I will look elsewhere. Oh, and I had to pay $99 for Mallick to come out and give me the honor of being quoted a drastically overpriced job. oh, and no, I turnd them down. It is one thing to have $99 stolen and another to have over $600 stolen. PS: the price included the senior discount! read more

CJ came by and fully assembled my new PRV, installed two shut-off valves, and my tankless water heater with ease. He was very informative, neatly set up the area, and went the extra mile in helping me move my 22-year-old water heater to be removed by a collector. Compared to other estimates, this company was very reasonable, and the quality of the work is excellent. Would highly recommend Mallick's Plumbing and the technician CJ for future projects! read more

Needed to replace the water shut-off valve on the wall behind our refrigerator that was rusted and wouldn't turn. They came, and did a good job replacing that valve that costs $20-25 and charged me $360 for 0.5 hr work. Called the business back asking for their hourly rate and they told me it is $344/hr. That was an expensive fix, but we needed it. 5 stars for the service, 1 star for the rate. It was my mistake not to get a quote before the service. read more

Had a leak coming from the pressure valve of my water heater, so tried Mallick. When the Serviceman arrived, I pointed out the leak and the probable issue as the pressure valve, but he seemed more focused on my valuable LEGO and Star Wars collection than the actual work, and was making comments like "this is all very expensive", etc. He then claimed that the issue was not a leaking pressure valve, but a far more expensive 1K job that he assured would fix the leak. He did not fix the leak, and instead did a completely unnecessary job that cost me over $1,000.00. When I complained to the company, they sent a different rep over that admitted the original work done was not the issue, and that the only issue was indeed a leaking pressure valve - which he replaced for an additional $500.00 (he also did not have all the parts needed, so I had to go to Home Depot myself to get them) When they started hassling me for a review and I pointed out that I was the last person they should ask for a review based on the incorrect work being completed, the rip off, and the overall experience, the manager contacted me but only offered to refund back half of the $1K spent on the original work performed that did not fix the problem, so I still spent over 1K on what should have been a $300 job. I believe the original technician saw my valuable collection, and figured I had money to spare, so he performed and charged me for completely unnecessary - and more expensive - work in order to jack up the revenue for Mallick and himself. Not to mention the unprofessionalism of the follow-up job, and me having to go get an additional part myself. I will never use this company again. read more

these guys have their act together! Kristen scheduled the appt. was professional friendly and flexible. Eric and Isiah were friendly, covered their shoes to protect my carpet, were quick and efficient. in addition to the expansion tank replacement, Eric indicated that he smelled natural gas by the furnace. When they finished the job, he updated me to let me know that he tightened the connection and checked for leak with his meter. Overall, Mallick was fairly priced, on time, and I would use them again in a heartbeat. read more

We called Mallick Plumbing this morning, our toilet started leaking and Ian Andrews was our technician. They were scheduled to come out between 1 and 3 and came right on time. I got a message they were on there way at 1:30. Ian was very polite and knowledgable. He found the issue with my toilet and was able to get it repaired. I would recommend Mallick Plumbing and Ian, read more

Updating my review because shortly after it was placed, I received a call saying the parts were in stock and someone could complete the repair work that same week; and I also received a call from a manager named Jeff. He saw my review and reached out to learn more about the situation I experienced, and he was extremely professional. The plumber who came to perform the work was also very professional: he arrived on time, completed all the work with minimal disruption to the home, and sent a summary email with before & after photos the same day. My estimate and experience with the office staff was subpar, but the quality plumbing service and management really made up for it. read more

I just had the most unbelievable exchange with this company. I own a rental property in Bethesda, and needed to do a few repairs prior to the new tenant moving in. I spoke with their office late afternoon Friday, and when I tried to confirm the appointment minutes later, after checking my calendar, they had already turned their phones off. So I left a voice mail, indicating that Monday as promised, was good for me, and that they could proceed. I heard nothing, until 9 this morning (Monday), when she proceeded to tell me that they were all booked for today and would have to schedule for Tuesday. Not sure, how with the phones off over the weekend, and with her call to me this morning at 9, how they managed to get all booked up for today, when she told me Friday late afternoon, that I could have a Monday appointment. Anyway, I accepted the Tuesday appointment instead . The purpose for my call was to have a dripping faucet fixed. When I was confirming the appointment, I mentioned that I live out of state, that the previous tenant has vacated, and the new tenant has not moved in yet. I wanted to provide the combo for the lock. I was then informed that they would not go to the house unless someone was there to meet them. I asked why, and she said it was company policy. I explained that I lived 150 miles away, and that it would not be possible. I have had an electrician, a painter, and house cleaners in the house, and they were very happy to work in the house, without tripping over people's dogs, furniture etc. There was no concern whatsoever for her pulling the rug out from underneath me, as I had already indicated last week, to the incoming tenant, that the plumbing repairs would be made today or tomorrow. This has caused me at least a week's delay, and for really no explainable reason. This is a clean, tidy, 4 bedroom brick colonial in a multi million dollar neighborhood...not some run down shack in a crime ridden area. The Mallick employee did not seem to care at all. Beware of relying on scheduling with this company. From my experience, it appears that they don't need the work. read more

My new to me townhouse had a water heater that was at least 14 years old. Although it was still heating water and not leaking, it did make some grumpy aging noises. The plumber I had used when I was renovating last summer was unavailable and going to be out for a long period of time. His voicemail recommended Mallick. I called Mallick and they were very personable over the phone. Due to COVID-19, I got to do a virtual call with Dale. I pointed out all my concerns and he asked for me to zoom in on some points of my old water heater. He said he would work on a quote for me and get it to me. And he did. Quote came quickly. I reviewed, but also wanted to get some other quotes for comparison. I used the Yelp option to send out a request to other plumbing companies. I did get replies, but only one other plumber gave me a quote. Others said they'd call to schedule a call but didn't. So, I ended up with Mallick. I mentioned that the quote was a bit higher than expected. Dale reviewed some options and we settled on a plan that would work for me for the next decade. Dale ordered the water heater and other parts. Within a week or so, Katee from Mallick called to schedule. Tyler showed up at my house bright an early the day of the appointment. I thought it was going to be two people, but it was just Tyler. Thankfully, my water heater closet is on the main level and right at the front door so he didn't have too far to go! Took about 4-5 hours for the new water heater, expansion tank, and all the other bits and pieces to get installed. Tyler was informative and explained what I needed to know about the new water heater. While he was wrapping up, I had asked him about some other issues about the pressure valve and other pipes that probably needed to get checked and replaced. Tyler quoted it out for me so I had what I needed to research. Good thing Tyler and I had chatted about it cause something wonky was happening with the water/pipes in the house. I got a lot of water hammering noise throughout the weekend. Draining everything and hoping air would get back into the pipes didn't help much. So, I called Mallick and asked Tyler to come back out. He came the next day and changed out the pressure valve. and checked for other issues. He was going to change the valve under the water meter for me, but had to have WSSC come out to fix the valve at the curb to turn off the water. After WSSC came out and fixed the valve at the curb, Tyler came back out to finish changing the valve. Good timing cause before he arrived, I could hear a toilet tank refilling. Tyler checked it out, did the dye test and there's a leak. So, once the parts come in, he'll be back. Mallick is following COVID precautions. Tyler has a mask and gloves. He's also mindful of property wearing booties over his shoes inside the house. Also careful to make sure the door is closed as he goes in and out of the house to his work truck. Incredibly polite. Definitely recommend Mallick Plumbing. #MOENFLO10 read more

Billy and Bryce were friendly, professional, and knowledgeable. They identified the broken part in the (very old) toilet that had sent water shooting out onto the floor from the back. I have had so much trouble with it over the years that I decided to replace it. Billy went over the options and helped me select one, then he went to get it while Bryce took out the old one. I appreciate Mallick for working me into the schedule on such short notice, and I appreciate Billy and Bryce for staying late on a holiday Friday to take care of this problem for me. read more

Another company doing work on my house yesterday told us they could smell gas in our basement and identified the source of a small leak in a gas pipe. My wife and I could not smell it - the leak was tiny - but it was there and it was leaking. I was then able to get Mallick Plumbing to send someone over within hours - on a Friday! - to fix the pipe. Tyler and his colleague did great work and stopped the leak within 1.5 hours. I am super relieved. I was very impressed with Mallick's responsiveness and professionalism, and I would happily recommend them to anyone in the area. Do note that they charge by the half hour, but to be able to go into a weekend not worried about a gas leak was totally worth it. read more

Brandon came to assess my Toto toilet. Asked him what the price was to replace it instead of repair it. Said he would need a minute to get the price from his computer in his truck. Left at 12:00. 1:00 came by, and he still had not returned. Needed to return to work. Meanwhile, he sat in his car on my street and did not return to my house until 1:20, 5 minutes after I texted the office that he had abandoned the job. He then returned to his truck, where he sat on my street until 2:15. I guess he really wasn't that busy if he could sit for 2 hours in his van parked on my street. Oh, and he had called asking if he could come early because he had "a very busy day ahead of him." Needless to say, we won't be using them again. Insensitive and disrespectful of client's time. 1 hour to quote the price for a new toilet? Seriously? It took me exactly 43 seconds to find the price on Google. Surely, it wouldn't take them 59 minutes and 17 seconds to figure out how much they would charge me to install it... read more

We called Mallick today to repair our leaking kitchen faucet and replace it with a new one we purchased. It turned out we had a clogged pipe preventing the flow of warm water as well. Mallick and specifically our technician Luis Lemus diagnosed and cleaned the clog and we were good to go and back to normal; just before a busy weekend. Thanks for your great service! read more

Yesterday was Sunday, I sent an email to Mallick Plumbing & Service to request for a service for my water heater which was only about 9 years old. Today is Monday and I received a call in the morning and asked me when I wanted them to come out. They did come less than an hour. The whole work took about 4 hours to remove my old water heater and install a new one plus replacing a dual check valve backflow preventer. The service was great and Luis and Ethan were knowledge to explain things to me. They wore shoes cover when walking inside the house which was nice. Everything went well, and now I have a new water heater to enjoy. However, by comparing the price from 6 years ago, it went up more than double. I didn't expect the price would be that costly. read more

We are very happy to recommend Luis and Mallick Plumbing. It's never pleasant to need an emergency visit from a plumber. It was a big relief when we were told Luis would be able to come out.
