Hartman Plumbing Services - New 40 gallon water heater

Had issue with my water heater. Darn valve went out. Dan…read morecame and was able to order a replacement and got it in ASAP. Very professional and prompt with their time. Will definitely use again and refer to friends that need plumbing needs.

I will only work with Dan for our plumbing needs :) He has helped us with several plumbing projects…read moreover the past few years. We first called him when a gas leak was discovered on our property, which ultimately required significant gas line work and replacement of the main line from the meter to the house. Most recently, he installed a new water softener and took care of several other plumbing items for us. He has consistently been reliable, knowledgeable, honest, and very easy to work with. He communicates clearly, shows up when he says he will, does excellent work, and takes great care of the property while he's working. His pricing has always felt fair and reasonable for the quality and scope of the work, and I appreciate knowing that the job will be done right. He also leaves everything incredibly clean when he's finished. On our most recent job, he hauled away the old water softener, took all of the packaging and debris with him, and swept up afterward. It's clear that he takes pride in his work from beginning to end. After using Hartman Plumbing for multiple jobs over the years, I'm very grateful to have found a plumber I trust and feel comfortable calling whenever something comes up. Highly recommended!

Major bathroom sink clog and Western Rooter is our go to for all our plumbing issues. Joe S…read morearrives at 8:27am and is as polite as can be. Comes in assesses the situation goes to his truck comes back with his snake and worked it out and was literally done and gone before 9:00am. But Joe S, again was very polite, respectful and skilled. He showed the black sludge buildup that he worked out and he cleaned under the sink and surrounding areas that had that back sludge from our plumbing attempts before the call. Theam is always great and Joe S definetly maintains that sentiment.

I can't say enough good things about my experience with Joe from Western Rooter!…read more Joe showed up at my house right at 8:00 AM to install a tankless water heater and a new shower valve. Before getting started, we talked for about 20 minutes and went over everything, and then Joe got straight to work. I have an older home, so I already knew there were probably going to be some challenges. Sure enough, Joe ran into a few issues along the way, but he handled every one of them professionally and never let it slow him down. He did an excellent job getting my new tankless water heater installed and working properly. After that, Joe came inside to work on my shower valve. He took the time to lay down drop cloths and protect my home before starting the work. Of course, he ran into a few challenges with the older plumbing, but once again, Joe figured it out and got the job done right. I couldn't be happier with the service, craftsmanship, professionalism, and overall experience. Joe clearly takes pride in his work, and it shows. If you're calling Western Rooter, ask for Joe! Not only will you get great plumbing work, but you'll also get a great experience from start to finish. I'll definitely be asking for Joe again the next time I have any plumbing needs. Highly recommended!

They were out the next morning and took an hour to find the leak and repair it to make sure we had no issues going forward.

Worst experience I've ever had with a plumbing company. I called today to have someone come out and…read moreassess an issue with my bathroom. When the plumber arrived, I walked him through the problem. He didn't seem to do much troubleshooting and appeared to be guessing what the issue might be rather than thoroughly checking. He quickly told me he was going to call his boss, Albert Diaz, for further guidance. After the call, he came back and began checking other faucets, but still only inspected one bathroom, even though the two bathrooms back up to each other. He gave me estimates for a couple of options he recommended. Because of how long the work would take, and because he had arrived late, I told him I would reschedule. Shortly afterward, I received a call from Albert Diaz asking what had happened. I explained my interaction with his plumber and told him that I felt the plumber was guessing and that I didn't feel confident or reassured by his diagnosis. Albert apologized and explained that the plumber was new and that he would work on additional training with him. I genuinely appreciated his response because I was simply providing honest feedback about my experience. The conversation changed when I began clarifying the estimates I had been given. It turned out that the plumber had mixed up the quotes, so I was trying to make sure I correctly understood the pricing. I asked, "Just to clarify, it's $500 just to run the camera through the toilet?" My intention was simply to confirm what the $500 charge covered--not to minimize the work or suggest that it wasn't worth the price. Albert appeared to take offense specifically to my use of the word "just," as though I was downplaying the service. That was not my intention at all, and I attempted to explain that I was only confirming the pricing, especially since I had already been given incorrect information. After that, Albert asked who had referred me to him and then told me that he would not be providing any services to me. I found the way the situation was handled extremely unprofessional. As a customer, I should be able to ask questions and clarify an estimate--especially after receiving conflicting pricing--without the owner becoming offended or refusing service. I was initially appreciative of Albert's willingness to listen to my feedback and address the training issue, but unfortunately, the way the conversation ended completely changed my impression of the company. Very disappointing experience, and I would not recommend this company based on the customer service I received.
