JNPC is the best!!! On very short notice, within a one week time period, JNPC obtained a city permit, re-engineered the lines, dug up the front lawn and replaced all the grass in such a way that it could hardly be noticed that the grass had ever been dug up in the first place, copper re-piped and replaced all the drains in the rental home without any loss of use to the tenants. JNPC installed many new cut-offs for all the water lines that was part of JNPC's engineering planning. The price for all the work that John Nelson did was excellent!!! This was the second copper re-pipe and drains replacement. The first was in the house where I live, and it was on the basis of that great re-pipe experience that I insisted on John Nelson Plumbing Company for the second one.
John Nelson has decades of experience, is highly efficient, is very reasonably priced and has the very best work crews doing the work which totally expedites all the multi-variant processes involved in the project from start to finish.
John is an honest man. He walks you through what needs to be done in detail. In the past, John Nelson has helped me by steering me toward contractors in fields other than plumbing who likewise have done excellent work!!!
You won't go wrong hiring JNPC for your re-pipe and drains replacement project(s). JNPC really is, at the least, among the very best in his field!!!

Super disappointed in John Nelson. I hired John to re-pipe my house a few years ago, all went well. I hired John to install a new water heater at my house about a year ago, all went well.
A few weeks ago, I hired John to install 3 water heaters in another building at a significantly higher cost than other plumbers but I used John because we had a good track record. I felt like he was my plumber and I could trust him. The work was done and a couple of weeks later the gas company came out to light a tenants heater. When the gas company looked at the new water heaters they said they were improperly installed and they red tagged 2 of the 3 water heaters.
When I called John's office I did not know exactly what the gas company had done, not being at the property but I told the office staff person that my tenants were saying the water heaters were shut off by the gas company and I needed them to check into the issue.
John eventually called me back and immediately became angry. I was very surprised and kept saying ""Wow, I can't believe you are talking to me like this"" All I wanted was for John to go to the property, determine the issue cited by the gas company, and let me know what would be required to fix the problem. In the process of trying to get John to stand by his work he said to me (in a very condescending tone) and I quote ""Stop pouting at me"" ""You cried wolf and that's not going to work"" ""I am not going to help you"" and the like. The whole conversation was really upsetting. I had just paid him thousands and he wouldn't even go look at the problem. He said something about fearing a lawsuit. Eventually said he would go look at the property if I sent him an email saying that he was going to look at the property but only as my ""friend"" and that he had no liability on the work. I refused and hired someone else to go fix the mess that John made. Sad and disappointed to have had this terribly negative experience with a neighborhood plumber that I thought I could trust.

Our experience was almost identical to Glen U's. Work took weeks longer than expected and the crew had to come back several times. They started demanding final payment prior to obtaining permit approval. We haven't had any problems with the plumbing, but we weren't satisfied with their process and lack of professionalism.

I'm not one to write reviews but feel it necessary to do so for John Nelson and his team; I applaud the fine work done by the company. From the moment I met John, I knew this was the guy who I wanted to repipe my old Spanish style house. I had already interviewed several. He was not the cheapest, nor the most expensive but he was clearly knowledgeable, caring, and persnickety about getting the job done quickly, cleanly, and with my 100%+ satisfaction in mind. The men did just that!
From the moment the crew showed up they worked beautifully as a synchronize team; they quickly laid the drop clothes, setup to get the work done all the way through to the spackle and clean up, seamlessly covering the holes necessary to gain access under the sinks and in the bathrooms. They paid attention to every detail of the job. One of the men made point to even ask if I wanted to keep some of the old fixtures, knowing that this old house had some special historic value. I am very happy to give John Nelson plumbing five stars - bravo!

After over 2 years, I just got a lengthy voicemail from John this afternoon asking me to remove my prior negative Yelp review. (So be warned Yelpers... more likely than not he has convinced bad reviews to be deleted)
I find it ironic that he, personally, never once attempted to address any of my concerns WHILE the work was being done.
In his voicemail, he essentially questioned if I was being vindictive by writing my experiences and opinion on Yelp. He digressed into talking about sprinkles on a donut (???) - I guess acknowledging one can't make everyone happy all the time. He continued to question my motives for writing the review essentially saying that I had my laugh and to please remove it.
No, my intent is never to be vindictive. If my reviews mis-state the facts, I am more than happy to correct.

John Nelson Plumbing re-piped our entire house with copper pipes. The work crew was very organized and took great care in protecting the working area and walk ways, before they started breaking the walls. They re-piped the house in 1 day, then came out the following day after the building inspector to patch up the walls (with texture).
Customer service was excellent with the office manager, who did all the work to attain the building permits, and was always available to answer any questions.
We did have a leak in a connection on the pipe leading into the house, but after a call they were out in less than an hour to fix the problem.
Thanks for the new pipes!!!!

We experienced the same scenario as David D. below. Had a lot of work done by Nelson in the early part of the 2000's with the paperwork stating Lifetime Guarantee on Labor and Materials provided by Nelson Plumbing Company. So with that we called to have them come fix a leak from our shower knob that they put in for us It took a few days for a call back but then was told that the part was lifetime guaranteed through Moen and we had to call them ourselves for the free part. Oh and my husband was told it would cost us $95.00, no wait I called and was told it would cost $125.00 to have this part replaced because they couldn't possibly send someone out for free to do a 5 min job that they on paperwork guarantee for lifetime.

Excellent work, quickly done.
We had 40-year old iron sprinkler supply pipes that burst at our Glendora home. John came out, sized up the situation, and gave us several options on how to fix it. Even though they specialize in interior repiping, they competently handled the outside job, tieing into the water supply in two different places, drilling under the driveway and through a block wall. They even added cutoff valves and hose bibs that weren't there before. Workers were professional and the price was very fair.

According to our experience, John Nelson's Motto ""COPPER REPIPE 4 LE$$"", is true.
We had an estimate for $1,500 more from a well-known plumbing company that was going to repipe our house with PEX. And that did not include patching any drywall holes afterwards. They would have charged thousands more for copper.
When we learned from a neighbor about the great job Nelson's Plumbing did, we made the all-important phone call and, after providing Mr. Nelson over the phone with detail of our house and its plumbing, we received his estimate by e-mail within 1/2 an hour.
Around 9:00 A.M. on the agreed upon date, a team of 6 plumbers, led by their foreman Sam, showed up at our door. After showing Sam the house inside and out, the team quietly and efficiently went to work without much ado, covering our floors with tarps and our furniture with plastic sheeting. It was very reassuring to watch these young, well-trained and polite plumbers quietly go to work. Without any instruction from my wife and myself, they performed flawless teamwork and interacted quietly with Sam and one another. It became quickly obvious that each one of them had his assigned area and detail while assisting others when they needed a hand.
We have had many workers in our home over the years, but we have never witnessed such teamwork. At 6:00 P.M. our house was repiped, inside and out, including a brand-new copper main, 4 outside hose bibs, new shower and bath fixtures and supply hoses in 2 bathrooms, as well as to the water heater and all sinks. The system had been checked for any leaks (there were none), and every hole had been patched professionally and even texture-sprayed (orange peel). These miracle workers cleaned all debris and vacuumed all work areas. Simply amazing! We can't say enough good things about Sam's plumbing team. - A few tips: 1) Trust that they know what they are doing and let them do their job. You will not regret it. 2) After the repiping is done, call the office, and ask for their written lifetime warranty. We received it promptly within 2 days.

I have used Nelson plumbing several times...they did a complete copper repipe of my house and got it done as was promised...my problem is the last 2 times I have tried to keep my business local and use him again, it is over a week before he gets to the job. This last time I called on a Thursday and he did not get out there until the following Saturday...simple job on a sprinkler valve and 2 leaky sprinklers...finally called me with his quote of 700 dollars to replace the valve....when I asked why it was so much he told me he had expensive labor costs....I asked him what the hourly rate of his services were he told me 200 for a plumber for the whole day...so I guess it would take one of his plumbers 3 days to do the job, because material costs were 100 dollars at most...told him to leave and he called me back to tell me he would do it for 500...when I got there, he had another plumbing company with him to do the work....this was a big rip off...my gardener did the job the next day and felt guilty charging me 120 dollars
