"Highly recommend Edwin and his professional crew. They were very knowledgable solving a complex drainage problem. Work was on time, superb quality, and fair/reasonably priced. Unlike some other bids that I felt were giving me the 'old lady' rate ;>"

"Super helpful and professional, support small business versus large corporate chains that treat employees like a cog in a machine and don’t care about their customers."

"It went great!!! Paul was extremely professional and came out with his crew to do a complete under house inspection. He then created a written estimate that was thorough and complete and easy to understand. They corrected some of the drainage issues that have been with us since the house was built. They obtained all of the necessary building permits (they had to cut through the pavement and re-pour the sidewalk) and the work was done in a very timely and efficient manner. His work crew (headed by a guy named Edmund) worked quickly and effectively. I believe that the 'measure of a company' is not only how well they do when they do the work but how hey handle issues that may surface after the job is done. About a month after work was completed, we noticed that we had a wet area and it appeared that there was a broken sprinkler pipe. Due to the efficiency of the drainage system that they installed, we didn't notice it right away. I sent Paul an email note and he quickly sent his crew out and they fixed the broken sprinkler pipe. They were extremely apologetic for having broken the pipe but more importantly fixed it immediately without question. I highly recommend Paul and his company. First, he really knows his stuff. Our house will now withstand the next 'Noahs Arc flood'. Second, he has incredible integrity. He does exactly what he says he will do and even more. They accommodated several minor requests including taking some of the excavated dirt and fixing the erosion with it even though it wasn't specified in the bid. Third, they stand behind their work. I cite the sprinkler issue above. Minor, for sure, but the fact that they said 'Don't worry, we will take care of it' means a lot. Not a lot of companies have that sort of customer service and commitment. Anyway, I highly recommend Paul and his company for your toughest drainage issues."

"It took a while to schedule, but once the job started it went as quickly as the weather permitted."

"Exceptionally well. Nak was prompt and available onsite for a quote, and talked me through all options, including tankless. He took the time to go over total costs of tankless vs traditional plus all other pros and cons. He was able to replace the existing water heater in a timely basis before it failed."

"From beginning to end, everything went well! They did everything that they promised, including taking good care of our new french drain that was located near the work site.  They arrived on time both days and cleaned up at the end of the day. They took all of my questions and concerns with a smile, and always took time to show me what was going on. I learned so much about my house and plumbing during this process! <br />"

"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. <br /> 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.   <br /> 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. <br /> 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.  <br /> 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.   <br /> I can only hope that Dempster has sorted out its personnel issues and holds to its commitments."
