We were very happy with Leahy Plumbing. They came on time, their prices are good and they did an excellent job. We were very impressed with the quality of the work and the level of service. Would use them again in a heartbeat.

Overcharged for installation of a Standard toilet. The helper was a pleasant individual; however, the plumber who installed it, John, had a terrible attitude, refusing to answer questions, and throwing tools around in our ceramic tile bathroom upstairs after I asked that they please be careful. When we called and talked to the owner, it was apparent he had received complaints about this individual before but was not willing to do anything to correct the situation.

The plumbers we had used from Leahy in the past were good, with decent attitudes, but after this last experience, we will never use them again or recommend them to anybody.

I won't bore you with the details but Leahy Plumbing will get it right --- maybe not on the first time but they will make it right and do it as quickly as possible.
Be mindful that it is the owner who is typically answering the phone when you call. Yes he is busy - I'd be a little concerned if they weren't. And I can only speak to my rather small problem we were having - they met expectations in fixing a couple of problems and when one of the fixes had a problem, John and his crew went beyond what I would expect to get it right and moreover, very, very quickly. I know in the world I work in things can and do go wrong - my clients respect me and my colleagues because we make it right immediately - same with Leahy Plumbing & Heating. They typically get it right the first time - but if they don't, you can be assured they will do what needs to done quickly and efficiently.

Had to call them to replace my garbage disposal recently. Tried to do it myself but could not get it to unloosen. With the right tools they had it off and the new one installed in no time. I personally have been using them for about 10 years. They are reliable and honest however, I don't think they work on the weekends. Each time I have called them they have been able to get out within a day or two.

Two days after Christmas and just when the coldest weather hit, our 22YO Ruud water heater started leaking. We chose Leahy Plumbing to install our next Ruud unit and couldn't be happier. We were able to get a phone quote since I already had info from 2 other contractors quotes. We had done our homework on water heaters and decided to go with another Ruud which the other 2 contractors didn't install. They were on time, worked efficiently, and had us up and running with hot water again in 2 hours. Very pleased with the service and will definitely contact them again for plumbing services.

They deserves 5 negative stars! Too bad I had to pick plus one.
Rude, threatening, argumentative, the worst customer service!!! After waiting 2 hours, gave a rude response to me asking if they were coming or not. Do not use them. There are so many other reputable and honest people to choose from.....

I learned of Leahy plumbing by way of a social media site. First of all the guy, John I spoke with, is always busy and in a rush, his excuse was the 4th of July holiday created a backlash of calls and so he practically hung the phone up on me trying to get off to answer other calls and in doing so I was not able to clearly state my extended issues.. He makes you nervous just talking to him - he makes you feel like you work for him instead of him trying to help you feel at ease about your plumbing issues. He had offered me a free consultation in a previous call several months ago which I took advantage of.

So I rearranged my day to stay home from work. He gave me a three hour window during the middle of the day. I had also reached out to him a few days in advance to exclaim that another separate issue had surfaced in which my insurance company recommended I seek out a particular service that a plumber could refer out or do for me in order to evaluate the situation.

I had called a few days before the appointment, and he was driving and claimed that he couldn't continue the conversation due to reception issues and asked if he could call me back. Of course, I understood, and of course I stated it would be fine. However, he never called back. But since we still had a standing appointment I figured I would discuss added dilemma in person when he arrived, since I wouldn't have to worry about being rushed off the phone!.

First of all there was never a follow-up call, never a call to let me know their estimated time of arrival not any call just plain silence! Well time passed and no one ever showed up and when I called, I was basically told by John that his guy was out working on another project that was more critical so therefore they wouldn't be able to honor my time slot which had already expired. He said we could reschedule - as though the day that I just wasted was not his problem and that I have all time in the world to waste as most of us do these days..

But he also further explained that since I was a ""free"" consult that basically they had no time for me. So I guess if they decide to give you a free consult you are considered a waste of time in their eyes and they could care less if they screwed up your day. And I also guess they figure someone like me would never even think to write a review about the one sided treatment I received due to the partiality of the situation. It was never stated to me that a ""free consult"" means they can abuse someone's time.

He also stated that since we got off to a bad start (certainly not on my account), and nothing is working out, that I should go back to my condo association and get someone there to look into it. Of course, now he's telling me he doesn't need my business and how i should handle the situation. I will give credit that he apologized a couple times during the call, but as far as I'm concerned it was a backhanded apology. The worst customer service ever!!! zero stars and two thumbs down!!

Plumbing problems are not easily diagnosed sometimes! I have used Leahy Plumbing for many years now especially on my rental property. They ALWAYS go above and beyond. Most recently we encountered unexpected plumbing problems after a new floor was installed. Leahy worked seamlessly with tile company to do an amazing re-tile / plumb job. Leahy is the bomb!

Needed an estimate for a water heater, there was no charge to come out. Showed up when they said, gave me a fair estimate. I decided to go with them and they installed the heater that day. Very professional, it was wet in my backyard and a bit muddy. They were very careful to put booties on their shoes and put plastic down from the basement entry to the work room where the heater was located. I would recommend them.

Disappointed. Had service done over two weeks ago and it took a week for them to call me back with the findings. I've asked for a written report so I can get schedule work for a mainline dig and replace and now it's been two weeks out we still haven't received my report. Service has been disappointing to say the least.
