Matt came over within the hour, fixed an almost clogged drain, and charged me fairly!

We had an appointment and MJ Plumbing completely ghosted us.

We called, left a message and sent a text.

Zero response.

Matt has come out twice to save the day for us, most recently on Christmas Day in the evening. He is a true professional and so kind. We highly recommend Matt.

The least professional business I have dealt with. Yes, his rates are reasonable, but he doesn't arrive as promised. The last experience that I had with him was when my hot water heater broke. He came in the morning, took the broken valve, asked me for a check to cover the replacement valve and said I would have hot water by the end of the day. As well, he promised to keep me updated, but that never happened. I never got hot water and I never received the valve. But, he cashed the check. Would not recommend.

Long-time customer. Matt and crew give 100% in service, follow-through and positive attitude -- a great group of guys you can really trust. Call them. You'll see.

Matt came to our rescue at short notice and got water back on to our house. He charged us a very reasonable rate. I like him and would recommend him to anyone. Thanks Matt.

Matt is epic. Service industry people just don't get any better. I had a non- emergency problem with my bathroom sink drain on the busiest day of the year. Matt assured me at 10:00AM that he would get to me today. He kept in touch and came , with my blessing, at 9:00PM. Fixed my sink with all upgraded parts, then made the mistake of asking my wife if there was anything more. She asked if he could make the bath shower head with more pressure. He did that improvement then fixed the kitchen sink faucet head that would not retract properly nor stay engaged tightly in the gooseneck. As he was saying goodbye at 10:40PM he insisted on tightening the screen door at the front door. CALL MATT.

Had an emergency with a shutoff valve. Matt came on short notice on a Sunday and did a great job replacing that valve - he was very thorough and went the extra mile by readjusting a faucet and swapping hot/cold lines for us.

Matt started out fine. We discussed the job and went over pricing. I wrote out a check for $2500 as a deposit. Two weeks later, he said he needed more money---which was fine, as the job was expensive. We mailed a check and Matt claimed he did not get it. A week later we were again at the house and since he claimed not to have received the check, we wrote out another one, this time for $3500. Then we did a stupid thing and did not stop payment on the ""missing"" check (which had not, at that point, been cashed). A few days later, Matt texted me that the check had arrived ""but I won't cash it, so you don't need to stop payment."" Some two weeks later, Matt cashed the ""missing"" check without our permission, knowledge or without telling us. Then he went on ""vacation"" and refused to answer my texts or calls. Not only did he fraudulently cash a check (felony?), after saying he wouldn't but he also failed to properly complete the job---despite having all of our money and then some. The valve to the kitchen sink, which he replaced, leaks and we have to shut it off. The one station on our heater does not shut off and so now we have to shut the whole system down went we are not there otherwise the heater runs continuously. Some kind of wiring issue, according to Matt. But he didn't come and fix it when I tried to contact him. Once I contacted my attorney, Matt offered to come by but now I don't trust him. He clearly needs money desperately---that's why he illegally cashed the ""missing"" check. We will see him in court but please don't use this dishonest plumber.
