Had replacement water treatment (sediment filter, acid neutralizer and softener) systems installed yesterday. Excellent work from start to finish. The installers (Scott and Nate) actually upgraded some of the existing plumbing in the process of the installation instead of the cut-and-paste work they probably could have done. Very pleased with the whole experience, and would not hesitate to use Waltz plumbing & heating again. The bottom line price for the quality of work done was very fair in my opinion, compared to other estimates we got. read more

Great company! We had a leaky pipe that caused water in the basement. I consulted Yelp for reviews of plumbers and settled on Waltz due to the number of excellent reviews. Yelp works. Waltz plumbers came promptly the next day, fixed the leak and we're "back in business". The Waltz plumbers are professional, trustworthy, knowledgeable and the cost of the repair was most reasonable. They are also great people to interact with..... I join with the other five star reviewers here to give them the same. read more

Timely response. They arrived as scheduled. Knowledgeable plumber with many years experience to who found a solution to our water issue. Very pleased. read more

Three and a half as there was a bit of a hiccup at the very start. We called them, they wanted to send a proposal by email, and they kept getting the email address wrong. It was almost comical how they had it compared to how it was supposed to be. Once the proposal was agreed upon, I did have to go to their office as they do not use docusign. So it would be a case of printing off the proposal, signing it and scanning it back to them. It was far easier to go there, dog. The agreement and give the deposit. Seemingly they are one of the few companies that still instal and service oil furnaces. So there is very little option to go with otherwise. The installation was done perfectly, minus one of the installers bitching about the access and the weight of the furnace. You'd think it was his first day, but he was 60 odd.

Waltz Plumbing is reliable, prices in line, if not more reasonable that most plumbers/HVAC companies, and always do quality work. For 2 years they have provided service to our HVAC unit. We've replaced our SUMP pump - called and they were here within 24 hours. Now we replaced water heater with Gas Tankless system. They coordinated with Washington Gas for new gas meter, county inspection, and did quality work over several days. The plumbers - Steve, Jeff & Jason - were exceptional to work with, as noted Waltz always shows up on time or calls to say they are running late (needed to get supplies), kept me informed of what they were doing, and cleaned up each day leaving the area even clearer than before. You call courteous office staff then quality work and exceptional workers, Jeff Waltz, and the entire company. read more

NE Bob Waltz Plumbing & Heating - Heating & Air Conditioning/HVAC Near Me - Frederick, Maryland

We hired Waltz to install our tankless water heater due to their professionalism, prompt response time, and communication. We had quotes for lower prices to do similar work, but Jeff Waltz's assurances and willingness to help us understand our options without pressure made the deal for us. Very thorough, very clean, and many more positive descriptions I could use to describe our experience, but I will spare you from an over the top description. However, if an over the top positive description was warranted for a plumber, this is the company. Recommend highly. read more

I had a great experience with Waltz Plumbing. I needed a water heater replaced and originally called another company who wanted $50 just to come to my house for an estimate. When I called Waltz they had me take a picture of the old water heater and they were able to give me an exact quote over the phone for a replacement. They came out the very next day and installed my water heater. The old one was so old they had to leave it in my basement for a few days to drain because it was falling apart and they couldn't remove it until it was empty. Some sludge drained out and clogged my drain. They came out immediately and snaked the drain to fix the blockage. They said that was part of the warranty and was covered by my original payment. Super friendly plumbers AND excellent service/workmanship. I'm a customer for life now! read more

My hot water heater broke and they had 2 guys out to my house within 3 hrs. The men they sent were personable, friendly, and thorough. I couldn't have asked for a better experience. Would definitely use them again! read more

We were having issues with the water pressure and I wasn't sure what to do. Thank goodness for Bob Waltz Plumbing! And for Steve and Jack who arrived on time, were so thoughtful and kind, and took the time to explain the situation and how to remedy it in the future. Steve actually walked me through the steps a few times. Their service is always exceptional and their customer service is the best. Very reasonably priced. Thanks so much to Steve and Jack! read more

After a new, used refrigerator was installed over the weekend, the ceiling in the basement below started to pool with water and drip. Chris and his assistant came out within an hour of my call and quickly diagnosed the problem. They were fast, polite, professional and spot on with the repair. I had called three other plumbers and could not even get through their answering services. The price was very reasonable and I am grateful. I would highly recommend this company! read more

The best in Frederick. Efficient, knowledgeable, courteous. Reasonably priced. If I have an HVAC or plumbing problem or need maintenance, I call Bob Walz. No need to look elsewhere. They're that good. read more

I have used other HVAC contractors in the Frederick area and prefer the people at Bob Waltz. All HVAC contractors have fixed my HVAC problems. The people at Bob Waltz, though, have responded more quickly, are nicer to talk to (both on the phone and at my home) and I feel like there pricing is most reasonable. One contractor charged over $500 for something that had not been a problem. Had I not been temporarily incapacitated, I could have easily done the work for $40. Joe Dorr Baker Park area read more

Great service! Fixed same day as I called, job turned out to be worse than expected but they really came through for me. Highly recommend this company. Very reasonable price for all the work they did. read more

I had a stuffed toilet after having some friends over. I called on Monday morning and they were able to come over that afternoon. It just needed a simple plunge. He said since he was in the neighborhood, and it just needed a plunge, he wouldn't charge me. You can bet I'll call him foe ALL my plumbing needs from this point forward!! read more

Called them a week ago and was told that the person who handles plumbing jobs was off that day, and that she would call me back. She didn't.

I can't say enough good things about the repair job I just recieved from Jim W. at Bob Waltz. I called for help in the morning because my a/c brok. Jim W. came out the same day took one look at the inside of my system, analyzed the problem, had the part it needed on his truck and fixed it Perfectly! He wore a mask and kept his social distance. He was extremely knowledgeable about HVAC systems and stated that he had over 20 years of experience. If I could give him 10 stars, I would. read more

I've lived in the Frederick area for more than 50 years. I've used multiple HVAC and Plumbing companies over the years. None of them have provided the prompt and professional service like Waltz. I strongly recommend NE Bob Waltz for all your plumbing or HVAC needs. Reasonably priced and the best possible service. read more

Jeff Waltz from NE Bob Waltz Plumbing went out of his way to do research to resolve a plumbing issue that needed addressed. With no promise that he would get our work, he came out and performed water tests on our property, explained everything to us, and made various recommendations and really understood the problem we were trying to solve. I highly recommend them. read more

I can see why these guys have such high review ratings. I had some routine work I needed done on some sinks in my house. They were fixed very quickly and professionally. I was also surprised that I wasn't charged an arm and a leg for the work- it was very reasonable. I've found my plumber for any future work I may need. read more

Love these guys. I know they have won Best of Frederick for the last several years and I can vouch for their excellent service. I had a new humidifier installed after someone else botched the job. They responded quickly, made a few custom parts, and returned within a day for the installation. Had to call them back for an air leak and they came the same day and fixed the problem. While they were there, they also looked at an unrelated issue and would not charge me. Love their honesty, prompt response and excellent work. Will not use anyone else after this great experience. read more

I cannot say enough wonderful things about N.E. "Bob" Waltz. My father has used them for years and recommended them to me. They are beyond prompt, kind, courteous, fairly priced, clean, and have excellent customer service. I will never use another plumber again. They have installed a boiler, water heat, toilets, sinks, faucets, and more for me and my family over the years. They stand behind their work and do an excellent and tidy job every time. I have likely met over half their staff throughout the years and have yet to meet one I did not like! I highly recommend giving them a call for any of your plumbing or HVAC needs. The ladies in the office are joy to speak with and will get you help promptly. read more

We had an emergency back-up. Billy and Dave arrived within two hours of our call, and immediately went to work fixing the problem. They also discovered that the toilet tank was leaking; not surprising since it was 30 years old. So while they snaked our drains, I bought a new toilet, and they found time to install it. They were very neat, careful, and thorough. They explained everything. They took videos of the drain and will get back to me if the video shows anything more serious. We are highly satisfied, and have found our NEW PLUMBER! read more
