Plumbing reviews in Baltimore, Maryland

Service was great, time was punctual and Zack was very professional. I’ve had this testing done for the past three years and Zack was the only plumber who’s explained that I’ll also need an annual descaling done. I highly recommend Trust Plumbing.

I had an absolutely excellent experience with Trust Plumbing & Heating. The Technician for my Backflow Testing was Zack. He communicated when I made my appointment to confirm the day and time and also when he was on the way. He not only provided great customer service but was very knowledgeable in educating me about what he was doing and why it needed to be done. To top it all off, Trust Plumbing gave me rock bottom pricing as opposed to several other providers who were quoting me prices three to four times what I paid.

Based on my amazing experience, I would gladly recommend Trust Plumbing to anyone needing plumbing and or heating services.

Thanks again Zack.

Zack and his team came over to descale our water tank. They were professional, courteous, super friendly, and efficient. I think they're great, and will continue to use them for their services.

Fantastic experience. Trust kept me abreast of each step, and their technician Zach was amazing, friendly, and professional. He also filed the necessary results to AA County, which Nationwide (whom I hired in April 2025 to first perform the test) did not. Cannot recommend Trust highly enough, and I would NOT recommend Nationwide for any of their services.

Zack is definitely your go to guy , I could not be more satisfied and pleased with not only his work, his quick response his willingness to help fix my issue. Most importantly he was completely honest with me from the beginning . I am so thankful that I was connected to him. I will never use anyone else and will refer anyone I know to him.

We had previously used Trust to replace a pressure relief valve and add an expansion tank to our hot water heater. Zack was very thorough and we were really happy with the work. We just had them come back to replace our main water line which was corroding and move it over a couple feet to make more space in the closet. While doing the work Zack uncovered a large void under the concrete slab and went above and beyond to make sure that it was filled back in properly before moving forward with the repair. We are again really happy with his work. We would highly recommend Zack to anyone looking for a trusted plumber!

My wife and I were very pleased by the service provided by Zack in replacing our valve connecting the sprinkler system. He spent time carefully explaining how the system worked both professionally and expeditiously. We were glad to get this accomplished and look forward to future interaction with his company.

Zack did such an amazing job with the quote, and Stephen and Derek did amazing work to replace my ~24 year old A.O. Smith gas water heater with this beautiful Rheem, connected to an Aquatherm. The pipe work is beautiful! I could not be happier having safe, hot water before the holidays and cold arrives. You all are an answer to the prayers of MANY people on my behalf!!! THANK YOU SO MUCH!!! MAY GOD BLESS AND HELP YOU ALL FOREVER!!!

Trust was wonderful to work with. My water heater busted and flooded my basement. They got to my home quickly, competently diagnosed the problem and took the time to explain my options for replacement as well as each of the pros and cons of each option. They also got to work quickly and installed a new water heater and a smart shut off valve on my main water line. My new water heater works terrifically. After the install I learned I may have insurance coverage for replacing the water heater. I called and asked if they could provide a letter to send to my insurance company. They responded super fast and I got notice from my insurance company that it was covered incredibly quick.

Extremely responsive. Worked with us on ideas to complete an outdoor project and integrated great with other contractors on site. Clean, tidy, professional and timely work. Highly recommended. Thanks again!

Love that their techs are conscious of my wallet! Instead of repairing plumbing issues whose life is about to expire they recommend replacement...that is just as cost effective as repairing. I appreciated the conversation. I highly recommend Mahon!

Mahon provided plumbing services including installing a new kitchen faucet and hooking up the garbage disposal. Shane was friendly, professional, and efficient. I would gladly call them in the future.

We use Mahon Plumbing as a subcontractor regularly to handle all kinds of critical plumbing issues. They are super dependable 24/7 always on time & only charges for whats absolutely needed, always at a reasonable price. Thank you for your excellent service.

We used Mahon plumbing to run a gas line and help with the insert of our new gas fireplace, as well as a couple other loose ends. Chris and the other men were all professional, knowledgeable and reasonable with the job & communication necessary. Will definitely be using Mahon Plumbing for all our future needs!

The team at Mahon Plumbing has completed many projects over the years at my work, my home and my rental properties.

The employees are so great and personable, always answering any questions I have and willing to educate me on preventative measures. I definitely recommend Mahon Plumbing to anyone, they are extremely reliable and sure to help you out!

My water heater was leaking pretty severely and I needed a plumber ASAP. I contacted Mahon Plumbing after seeing their reviews and they were at my house within a few hours. They notified me that my water heater was under a manufacture's warranty and replaced it the same day. The two gentlemen that came out to do the work were courteous, professional, and left the area cleaner than they found it. I highly recommend Mahon Plumbing for any plumbing needs!!

LOVE this company. They were the second company I called with my emergency (occurred over a weekend of course!) Somebody called me back within 30 mins. - explained what I needed to do temporarily and they showed up - as promised - Monday morning and did the permanent work. The work are was cleaned, the tech was polite, and the price I thought was very fair.

I contacted through a friend’s referral for backflow valve inspection per my county’s requirement. The whole staffs at Mahon, from the receptionist who answered my call to the plumber who came for the work, were very friendly, courteous, and knowledgeable. They provided me with an exceptional experience. The expectation was clear and I was provided with all the information on how things will be handled hassle free for me. For all my future plumbing needs, I am calling Mahon.

We use Mahon plumbing for all our Plumbing needs. Prompt scheduling, technician arrives on time. Greg is very pleasant and professional.
Price is always as quoted.
10⭐️ I highly recommend Mahon Plumbing!

We had a water leak and Mahon Plumbing came to our rescue, saving us thousands of dollars. The owner of the company, Greg, and his son, went out of their way to help us. This is an honest company with good values, fair pricing and good work. Highly recommend!
