Couldn't hire a better crew. We hired them for a sewer replacement and plumbing for our new addition and the work is flawless. Will recommend to friends and family.

I have been on the fence about doing a review of Dempster Plumbing, but a recent issue with the handheld shower (not Dempster's fault; Moen's issue) has pushed me off the fence.
I had several bids and conversations with plumbing companies, and based on my interaction with Corey from Dempster's Plumbing, I elected to try them.  Once that decision was made there were many conversations with both Corey and Moen about the correct shower valve, and finally one was on it's way. We elected to do Part 1 first as Part 2 would be a bit more complicated.  Corey arrived on time and took care of replacing the faucet, disposal, and re-circulation system expediently.  So far so good, and I love the faucet and re-circulating pump.  
Corey was going to come the following day, Saturday, to start Part 2, but I said Monday was fine. He told me he was getting married on the 8th (think that is correct) so he'd not be here then. We set another date, but that date came and went, and neither Corey nor anyone else from the company contacted me. I called the company to learn that Cory had quit, and there seemed to be other employee issues as well as the company's owner was out of town on a family emergency, and the individuals I had been working with were also no longer available.  Eventually a new date was set and a team of four or five guys showed up. I was quite surprised as this should have been just a one or two-man job.  Come to find out when work was well under way that my project was being used as a teaching lab for the install of new PEX lines to copper lines. I spent my life as a teacher; I understand the importance of training.  That wasn't my issue.  It was the lack of courtesy of asking if I minded before hand not an, "Oh, by the way, do you mind..."  What should have taken no more than a third to half day ended up taking a full day.  By the end of the day, I had a working shower, and I really just wanted them all gone; however, I did point out that the shower arm was very short, and I'd be running into the wall, which I do. As a result, I mostly use the handheld shower instead of the overhead shower. The supervisor said he had another, longer shower arm he'd install, but that never happened, and I will eventually get around to buying a longer shower arm.
Now comes the tipping point.  Moen's shower slide is poorly designed.  I've been through several of them, and recently, it failed again.  Moen has been wonderful about replacing the part, and the new one arrived a couple of days ago. I have to remove the bar from the wall to replace the slide, and once I did that, I discovered that someone made an error in measuring for the installation of the handheld bar.  Instead of one drill hole, there are two. No "measure twice, cut/drill once" here.  Would have been nice had the error been acknowledged so it could be filled when a couple of other holes were addressed...begrudgingly. 
Overall, the job was more or less satisfactory in that everything functions; the process of getting there left much to be desired.  Prior to having my work done, I even recommended Dempster to a couple of other residents for whole house re-pipes. One had a good experience; the other not so, and I'm embarrassed now that I recommended Dempster before having my work completed.  
I can only hope that Dempster has sorted out its personnel issues and holds to its commitments.

My experience with dempster Started off well but ended rather poorly. The plumber who gave me my initial estimate and oversaw the work was Cory. He was personable and explained things well. The crew was at my house from July 13 through the 15th, And they were generally polite and tidied up after themselves. The water heater installation was not part of the original job; it happened to die on me the night of July 13 , And since the plumbers were here anyway, it was a relatively easy add on. When they left on the 15th, I was pretty satisfied with the job. Then a few days later I noticed the faint smell of gas in the garage. At first I thought it was my imagination, because I watched the plumbers spray all the new gas lines with that bubble leak detection solution, and it showed no leaks. but then I kept catching the scent so I gave them a call on July 20. Cory came out right away, confirmed that he could also smell the gas, but when he sprayed The solution to find a leak, he couldn't find one. So he resealed /tightened the gas lines going into the water heater, and we thought that might do the trick. Well, the faint gas smell kept coming and going. It was bothering me so much that I got my own leak detection solution from the hardware store, and put it all over the lines, but I couldn't find a leak source despite catching whiffs of gas. so I called again on Friday July 24. Cory came out again, and I asked him if The water heater itself might be leaking gas (until then, we had only been spraying the lines leading up to the water heater, and no further.) . Cory said that the water heater should be completely tight, and ruled that out.Since the water heater was brand-new and obviously under warranty, Cory said he would Call the manufacturer , And if all else failed he would swap it out.it was it was mid Friday afternoon by then, and we agreed that he would contact me back about it on The following Monday. On Monday, I finally actually found the source of the leak. I sprayed the panel of the water heater (which The plumbers hadn't inspected at all), and bubbles foamed up at the little tube that feeds gas to the pilot. So I calledDempster right away to get hold of Cory, And was abruptly informed that he had quit that day. Not only that, but apparently Cory hadn't told contacted the manufacturer or informed anyone else at Dempster about my outstanding gas leak issue. So I tried to explain the situation to the person I was talking to (William). And he got extremely short with me. Honestly, it felt like he was mad that Cory had left so abruptly (which I can understand), and he was taking it out on me (Which is rather unprofessional). He did agree to come out to take care of the leaking line, But he only showed up with a wrench and sealing compound. He didn't bring his own leak test solution, Which I found baffling (because he was coming out specifically for a gas leak) and kind of annoying (because he asked to use mine and I was just about out). At this point, I haven't smelled any more gas in the garage so I think that my water heater situation is OK now. However , after that experience, I really hope The rest of their work holds up so I won't have to ask Dempster back about another warranty situation.
Response from Dempster Plumbing
"The actual leak was a manufacturer defect, We can't understand why a person would say we wouldn't honor our warranty? Dempster Plumbing honors all its work whether the customer is happy or unhappy. We have installed thousands of gas lines and on a very rare occasion the gas tubing on the water heater was having a very small leak it seems the customer believes that we did that part of the work but we didn't and we did come out several times in attempt to find the leak and eventually solved it."

When I called them the second time, I realized the part for the toilet leak was something ridiculously cheap, and they charged me $137.00 for the work and then after the guy left the first time, I noticed that he didn't turn the water heater back on, and also a few months later, I noticed one of the faucets that he installed was leaking, but I think the warranty that they gave was already passed 30 days. I actually didn't realized that the faucets have failed until after I called them back the second time and after I paid them a ridiculously high price, and then I just realized that they're a little expensive and the work is not all that great.

Overall it went well. Team was on time and mostly cleaned up after themselves. We had two minor callbacks due to the same joint leak (where new copper was joined to a small run of existing copper). One other issue was they helped us clear all the sediment out of the faucets upon completion (as a repipe loosens up a ton of sediment), but they had left two supply lines under the sinks only finger tight and they started to leak -- but I guess after every major plumbing projects you should be on the lookout for leaks for a few weeks after.

It was low cost of inspection and I was satisfied with review of the house water system and decided not to change piping.

Corey came a couple of days before work was started and explained to me the whole process. All the the workers were super nice and professional. their work ethics were awesome. I had to stay there and they worked around me and I didn't feel in the way. Corey made great suggestions about different types of facets and toilets especially since i have limited mobility
the guys were great, the work was finished ahead of time.  This was a lot of money to invest in a job and I truly made the right choice choosing Dempster plumping

It went great, problem was spotted and diagnosed right away and I was walked through the fix in detail, along with good tips on what to look out for going forward and the best way to deal with it. Very honest and up front specially about when it was worth to call a plumber and when it wasn't necessary. Same for the condition of some older faucets and the options regarding installing a water softener for our condo. Great experience overall, particularly regarding good communication and awareness of what was covered with the AL visit and what would be extra, as well as time and cost needed for different options. Very happy.

This was a very atypical sort of job for a plumber and the other plumbers I called either declined the job or quoted ridiculously high estimates ($4200 in one case). Dempster Plumbing gave a reasonable estimate for the amount of work required, and did the job to my perfect satisfaction. They made a real effort to ensure that I was happy with the work and I really appreciate that! I expect to use them for ALL of my plumbing needs in the future.

Val did an amazing job.  He made sure everything was done right and to our liking.  The only issue was that the project took longer than expected.

I had crawled under, found the problem and was preparing to put a temporary patch on what I though was a small hole when it became evident it was a 5 ft long rust-through line in the drain pipe. They came out, verified the problem, made a quote and agreed to replace a 20 ft section of pipe the next day. They came out and replaced the pipe in about an hour. Called back a year later when the new/old pipe joint developed a leak. They fixed that promptly, at no charge, about an hour after we called them.

pLUMDempster Plumbing was very punctual. The person they sent out was extremely knowledgeable. In order to flush the toilet they had to snake through the roof. The boss came out to help. They then snaked a camera clear to the street. Just a major mess. Old, cracked and broken pipe, with roots abound. Also the pipe from the kitchen was extremely corroded. It was on its last legs. The washing machine needed a new hook up because the last solution I paid for (5 years ago) was not very efficient and created other problems, such as noise when the rinse cycle was on. Very funky. Quite frankly, everything to do with pipes needed replacement. As said early, they were extremely fast and reliable. I thought their financial arrangement was fair, considering all the work that had to be done. They were very professional solving this problem and the end result has given me peace of mind. I am very glad Angie's List recommended Dempster's Plumbing. Originally I did call Angie's List for recommendations and they provided three. So Thank You Dempster Plumbing. It was a pleasure doing business with you.

The work went very well, and I am very happy with the results and with how Dempster went about their work. First, they were very fast. They had my house entirely re-piped in a day. Granted, the house is small, but it was still something they thought would take two days. The holes they had to cut in the walls took a little longer to patch, but that was because of the scheduling for the city inspection. The patching of the walls were done beautifully, by the way; except for the variation in color from the paint, I can barely tell where they made the hole to get behind the bathroom sink. They were also very neat and concerned about leaving things clean. They put down tarps not just in the working area but also along the paths they had to walk to get to their supplies. Finally, the inspection went very smoothly: the inspector made a couple of minor suggestions, but no changes were required, and he signed off on the work.
I'd also like to comment on their demeanor. They were very professional and very friendly. I enjoyed having them work on the house, which is something I'd not expect to say about plumbers. Usually, they are the heralds of watery doom. These guys are definitely my go-to plumbers from now on.

Hot water system seems to work well.  Radiant heating worked ok at first, but has since crapped out.  However, it doesn't appear to be related to the water heater install.
Dempster plumbing was very clear that they don't do radiant heating, but did their best to find a suitable water heater rated for the dual purpose that the old one was serving.

Bill explained everything in detail while giving the estimate. He was the only plumber not scared off by the age of the house and the old plumbing. His crew had no issues working under this old home and dealing with plaster walls. They patched everything up so that you could not tell they had worked there. Other plumbers had said we would be responsible for cleaning up after they had cut open the walls. The crew was friendly, polite and seemed to enjoy working together. The inspector from the city told us we had good quality work done and also commented on how nice the workers were. How often do you hear that?
Overall an excellent experience. Almost want something else to break in the house so that we can hire them again!
