We called Mahon and appreciated their rapid response and superb work to correct a leak caused by the deep freeze this past winter. We have a ca1930 house and discovered a slow leak buried in a wall of the guest house. Shane's decades of experience made quick work of this repair with impeccable copper line replacement and installation of new ball valves so we can properly winterize this space next winter. Many thanks for this excellent service at a reasonable price. read more

Mahon plumbing did a wonderful job helping us with a backup in your drain and installing new sump pumps. they were professional every step of the way, and would recommend them to anyone read more

We had a tankless water heater cleaning service performed and the technician was very professional, courteous, and polite. The work was completed as described and within the time frame that was discussed. read more

Mahon services were timely and communicative with my shower leaking issue. Very thorough. Will be using them again

Mahon installed a new toilet this week. The tech arrived on time and did a very neat job of installing and hauling away the old toilet.

Mahon was a contractor for our new build, and we have used them ever since - that was almost six years ago. The technicians are professional and dependable. I highly recommend Mahone for your plumbing needs. -LaVerne N. Knight read more

I had a leaking shut off valve on the waterline to a remote garage a couple hundred feet away. This was during that recent cold snap we had where every plumber was busy thawing out pipes and repairing frozen pipes but I called Mahon plumbing and Chris immediately said give me a minute and I'll call you back he did and had a guy stop in my house between jobs within a couple hours And he brought everything he needed because I had sent a picture of the situation and from that they analyzed it then the guy showed up with all the tools he needed and a truck full of spare parts. He had the latest pipe connecting technology I knew the days of gas flames and soldering were probably gone And there's the technology that's available to us amateurs where we can push. The pipes together is also surpassed now they had the latest connection technology and the equipment they needed to implement it and I got a beautiful job done in no time at all and I stood and watched a technician, and he explained every step he was doing and it was really educational experience and then for a very reasonable price it was fixed, and he was out of there. so I gave them a five star rating For the way they operated so professionally. (Excuse the voice texting probably got a couple errors in there ) read more

Fortunately I do not have to often use plumbing services but when I do it is for an emergency and when you have an emergency, Mahon plumbing is the company to call! I recently had a sewage back up in my basement and Mahon was on the scene within 90 minutes to snake the pipe. They put a camera in the line and found another obstruction further down the line that was the counties responsibility and gave me the county emergency number to call to clear that out. When you have a plumbing emergency call Mahon. They have the expertise and professional staff to get you through it read more

I had a new bathroom remodel done in my home in October. While the company was still working in my home on other projects, we started having problems with our toilet backing up. The remodel company tried fixing the problem, only for two day later, it to happen again After a few failed attempts a different plumbing coming came out to fix it. They told me they snaked my toilet and it should be better .... 5 days later the toilet was backing up again. A friend who is retired from a plumbing career, and was an inspector for the state, recommended Mahon plumbing to us . After struggling with this problem for a month and a half, and finally not using the toilet, Mahon came out and solved the problem!! They found a piece of pvc that had fallen into the toilet during remodel . We've are so happy to say that Mahon plumbing has allowed us to enjoy our new remodeled bathroom ..... at last!!!! read more

Mahon Plumbing did an excellent job. They were very responsive. When our water heater got fried on Easter Sunday night during the COVID19 crisis, they were the very first to respond. Chris immediately dispatched his technician. Mike took care of the burnt panel and the leak and recommended the tank replaced. The following morning, the crew (Shane and Ray) replaced the tank. The whole transaction was very smooth. We will definitely call again for any plumbing work. Thank you! read more

Mahon Plumbing provides timely and professional services every time! I've used them numerous times and they're always consistent. They've given me great advice regarding how to avoid backups in my plumbing system. From upgrading my toilet to cleaning my hot water heater to replacing my sump pump, Mahon Plumbing has been awesome to work with! The time their technicians take to explain things is especially appreciated. I'd highly recommend Mahon Plumbing for all of your plumbing needs! read more

Mahon plumbing is excellent we had a great experience Dealing with a plumbing emergency on a Sunday night A friend recommended to call them we did on Monday morning and Chris was very helpful and had someone out a few hours later Tim who came out to the house was very professional and did an excellent job We will use Mahon for all our plumbing repairs in the future as will other family members Definitely recommend read more

Thanks Manhon. I'm looking forward to a master plumber . Please come thru . The in person assessment was wonderful

Mahon plumbing was very professional and showed up when they said they would which isn't always the case with these type of companies. They repaired the main water line from our well to the house and were able to have it completely done within a couple hours. They even went to the point of putting down hay and seed where they dug up our yard (to fix the pipe), can't recommend them enough, if you want great quality work this is the plumbing company to use! read more

Tim showed up wearing a mask. Took out our old garbage disposal and put the new one in. Very neat and quick and arrived at time stated. Very happy with job. read more

I've had Mahon do three projects on my house now and I've been impressed every time with their professionalism. I'd trust them with any job in my house. read more

Cannot say enough great things about Mahon. They helped us navigate an issue that came up during the home inspection of a house we were purchasing. Mahon went above and beyond in negotiating the issue with the sellers. They ultimately replaced our sewer line and did a truly professional job. Highly recommend. read more

A good friend of mine owns his own plumbing business in Texas so I hold a pretty high standard when it comes to good plumbing service. I must admit, I don't know a lot about plumbing, but I think I have a general idea of fair prices and what kind of work is needed. I've used Mahon Plumbing twice for two different homes in the last two years. They sent out different plumbers both times. Plumbers in general are pricey so you may want to do some comparisons, but they are friendly, stick to the discounts they offer and do decent work. read more

Mahon Plumbing saved me! They came in when other companies said they'd have to wait for my yard to dry after multiple days of rain and snow. I had to have my whole sewage line replaced after a belly in the pipe that left a great surprise in my laundry room on Thanksgiving. Thank you Mahon Plumbing! read more

Quick reply to request. Excellent communication. Honest, good and fair price. Excellent service. Would definitely recommend to all my friends and family (and I have a large family) and store in my contact list as my go-to plumber!! Thank you Chris Mahon and crew! read more

Was not happy with service. Their emergency line says 24 hours, but when I called they kept trying to find ways to dismiss the plumbing issue instead of getting a tech to take a look at it. You have to really push if you want a timely appointment. I had to do my own research to fix the problem. read more

After our pipe burst we called several plumbers but Mahon Plumbing were the first to follow up in a timely manner. Their plumber, Sean, was professional and efficient. He even cleaned up after finishing the work. read more

Mahon plumbing saved us a ton of money on a main water line replacement and did an excellent job. They gave us a quote and were out to start the job a couple days later. They did a quick, great job and I couldn't be happier. We had a couple other quotes that were much higher, mahon is great. read more

Had these guys come out to quote some work. They seemed interested in the job when here, seemed invested, but we can't get past the bitchy secretary from hell. She is awful to work with and we've lost interest entirely in working with them. read more

Mahon plumbing is the biggest, most inappropriate people I have ever met. Greg Mahon might be the biggest asshole on the planet. He is building a home near mine and I have heard nothing but terrible things about him from all of the neighbors around him. He doesn't notify them of anything, has caused all kinds of damage he doesn't plan on taking responsibility for, and make consistent rude and completely inappropriate comments. I went and talked to him personally about some damage to my property and he went off on me and my wife. I mean went off. Saying that I was this and I was that. I really didn't know what to say in response as I was totally taken off guard. I have asked around about him too and Anne Arundel County officials as well as other local business owners all know and are familiar with how inappropriate this guy is. One County official just rolled his eyes and said, "we have had more than one complaint about Greg Mahon." If you need plumbing services or anything for that matter please look for another service. Mahon Plumbing could possibly be the worst people on the planet. I am not joking. read more

Call Millennium Instead (410) 265-8833. We had a Sprinkler pipe freeze and burst in February and called Mahon so that we could get water back. We had specifically told them on the phone that it was a sprinkler that had burst but when they got to our home they told us that they didn't work with sprinklers (shouldn't they have shared this information over the phone?). Instead the guy they sent had us write him a personal check and he put a valve on the main line to separate the sprinkler. Since it was a personal check with no receipt we could not submit it as part of the insurance claim. He told us that the sprinkler repair people would be able to remove it. When the sprinkler repair man came he told us he didn't have the tools to work with compression fittings and that we would have to call Mahon to remove the compression fitting since sprinkler pipes are PVC and they don't work with the metal. When we called Mahon back they first told us they never did anything of the sort, when I gave the dispatcher the name of the plumber they had sent she was surprised and said she would talk to him. They insisted that the sprinkler people would be able to fix it no matter how many times I explained that they had already been to our place and told me they could not. They completely ignored me and were extremely rude. I could under no circumstances convince them to schedule a visit. We finally resolved the issue by calling Millennium Plumbing (410) 265-8833 they had to cut the valve away. read more
