Recommended Customer Reviews

So disappointed - in past no problems with this company - they came out and told me I needed a new faucet for kitchen - I paid up front for them to get faucet (my fault) and seven weeks later NO FAUCET & no calls to let me know what was going on - each time I tried to call the mail box was full - finally after 7 long weeks of washing dishes in the bathroom and much pleading I got through to phone and demanded my money back - waited over a week to get money back - if you have over booked yourself OR don't want the job just say so up front

I absolutely applaud the prompt courteous service that I received from Mike R. ! He has done several jobs for me in the past such as unclogging my drain lines and detecting a leaky toilet problem after my water meter started running amok. I am about to replace my water heater and guess who I am calling? Yep! Rosenberg Plumbing.

I've called Rosenberg Plumbing twice in the past 5 or 6 years. Both times, he came at the stated time, did the work, charged the stated price, and made some suggestions for future work that might be needed. What more could anyone want from their plumber?

Like another reviewer, I had used Rosenberg Plumbing when it really was Rosenberg Plumbing (many, many years ago). The original owner was fantastic. I don't know when Mike took over, but I started using his services about 5 years ago. He's been fine. But this last time, he promised to send me an invoice and hasn't. I've called him several times (I hate feeling like a pest). Like other reviewers' experiences, he hasn't returned my calls. Maybe that's why he screens calls.
I can forgive the big mess he made when he changed my water filter the last time he was here ... water everywhere. Everyone makes mistakes now and then, although he said that was the second time that week he made that mistake. Unforgivable is not keeping a promise you make. I paid him, he cashed the check, but never sent me the invoice he promised. It's been over a month now.
I'm sorry to say that I won't be recommending him any more. Mike, clean up your act!!

so he charged us 1400 dollars for work that he never completed and never even gave us a receipt. This is a slimy guy. Very sad to work so hard for my money and then be taken advantage of. He will not return calls to discuss it and has a phone system where he screens the calls so he can avoid folks he has misrepresented himself.
Calling the BBB on this guy. this has been a lesson in not being so trusting for me.

mike is my go-to guy. sometimes he's busy. sometimes he's late. so minus one star. but he has always come through for me.

I called Mike on Monday morning as our water heater was dead. Mike was able to give me a firm quote over the phone. His price was a $1000 less than a scam company called Affordable Water Heaters which tried pressuring us on Sunday to commit to their installation. Mike came out a few hours later to size up the situation. He came back out later in the afternoon and within less than an hour he had the new tank installed. He was prompt, efficient and knew what was he doing. I would not hesitate in referring business to him.

I am not sure about the history of this business but I delt with Mike Rodriguez. This is the chain of events of my experience with Mr. Rodriguez. Called to have a valve replaced. He said he could make it out to the office I was located at the following day. Few days go by with no response. I receive a follow up call from Mr. Rodriguez filled with apologies and we rescheduled another date and time to have the job done (either the next day or the day after that). Still nothing. Then, it must have been 3 or 5 days later a tall gentleman enters my office. I say, ""Hello, can I help you?"" ""The job is done"" ""what?"" No warning. From what I was told from the other people occupying the building, Mr. Rodriguez walked into the building. Told the person at the front desk, ""the water is going to be shut off for an hour"" and then completed the job. I am writing this review because I just saw the invoice. $200 something for the parts (understandable since it is a commercial toilet, sure) But $165 for labor / service fee. Last I checked, I do not work in the White House. So, needless to say, I was not pleased. Also, on the day and time Mr. Rodriguez was suppose to arrive, we circulated a memo to the rest of the office building that water was to be shut off at 4:00 pm so, employee's left work early because of this.
Why 2 stars? 1 star for getting the job done. Another star because Mr. Rodriguez (from what I can tell) is a pretty nice guy. Sure he may charge an arm and a leg for labor / service that should only cost approx $60-80. And sure he may have been a week and a half late to the job. And sure he could have chosen a better way of alerting people in the building that the water was going to be shut off. But, I believe he is a nice guy who just needs a better way to organize his time and work. Maybe even a secretary could probably do him wonders. But he is a hard worker. I wouldn't recommend him to anyone though.

i have called Rosenburg plumbing a few times.
last week i called with a clogged toilet. he charged the base rate of $120. and also did maintenance on a tank less water heater and adjusted 2 other 5(?) gallon water heater he had installed in the past without an extra charge. The next week later called back with updates on the maintenance challenge needed on the tankless.
thanks for your follow up.

Mike is a cosumate professional with clear and concise best practices he follows, there are no surprise pricing attacks, He will always do his best to provide you with excellant service. I would highly reccomend him to any of my friends and business partners. in todays world it is very hard to find someone with integrity and is trustworthy.
I think you should branch your business out to the East Bay, we need a company like yours.
Thanks you MIke.
