    Paul was wonderful, and quickly repaired the heating unit on top of our science lab at our school.

    We've been without hot water for two weeks (and counting)...in sub-freezing temperatures because of…read morecompany-wide incompetence. Our tankless water heater stopped working on a Friday afternoon and flashed a code. We contacted WMH because we have a service contract with them for the entire house. They wouldn't send anyone out until the following afternoon. The technician identified additional parts that were needed to complete the repair and ordered them from the manufacturer to be delivered directly to our house ASAP to avoid hassles with their warehouse (very appreciated). The problem is that he failed to order the parts related to the initial code that prompted the service call in the first place. We were out of town (thankfully) for several days and when we returned on a Saturday, the part was waiting for us at home. We called WMH first thing on Sunday, and the wouldn't send anyone until the following day. At this point, we'd been without a water heater/hot water for 10 days. In literal freezing temperatures that prevented snow from melting for weeks. No sense of urgency on their end whatsoever. By noon on Monday, no one had come to the house or called. We called to get a status update and were told that the technician didn't find the part in the warehouse, so he didn't come to the house. No one called to tell us this. If they had, we could have told them that WE HAVE THE PART AT THE HOUSE! They send he would come out later that afternoon to make the repair. Then they called back after an hour to say, never mind, the job takes too long so they won't send anyone until the next day (Tuesday). It's Tuesday (12 days without hot water), and the technician finally appears in the morning. After working for four hours and installing the new part, he tells us that the prior tech failed to order the parts needed to correct the flashing code (i.e., the reason we called them in the first place). They had to order the part, wait for it to come in, and then schedule another service appointment. We asked that it be sent directly to our house so we could keep track of it and use another service provider if we wanted. He agreed. By Thursday (our 14th day without hot water), we had to call WMH to ask when we could expect delivery of the part because it hadn't shown up yet. They confirmed it had been ordered but would get back to us with an ETA. They never got back to us. Friday morning, (15th day without hot water) we called WMH to get an ETA on the part. They said it had been shipped directly to their warehouse (contrary to our wishes) and that they'd be sending someone to make the repair that afternoon. We're still waiting for that technician to show. In the meantime, we saw an Oliver van pull into our neighbors' driveway and promptly setup a maintenance contract with them and will be using them to finish this job if WMH is yet another no-show. Maintenance contract: We have a service contract with WMH for several years and not once have they showed up on the scheduled service date. Nor have they called us to let us know they weren't showing. So we miss work that day and then have to miss work another day for when they actually do decide to show up--but they only show up if you micromanage them. And we do not have time for that, especially when their customer service is abysmal and their services are objectively over-priced!!!

    We were very fortunate to have our heating system break down, but able to be maintained heavily…read morewhile we shopped around with time on our side for a new system. We got 4 estimates in total. In all honesty, the prices were not super far off - the recommendations, or lack of were the biggest variable between all of our proposals. This is kind of long, but like others have mentioned, the experience was so good that I wanted to make sure to take the time to give this feedback. 1. Borden was the only one who recommended a chimney liner in our new system. Which is important in the newer 84% because the temps are not as high as they used to be. But even more important in the 90% model where the water heater would be an orphaned appliance. Which is actually a pretty serious safety concern. 2. Borden was also the only one who recommended a new expansion tank and offered to cut back to the steel one if we wanted to shave a little off of the price. A number of places i looked said that the amount of new installs they see using an older tank is mind boggling. And there are numerous benefits to the new style including eliminating air, rather than just controlling it. 3. Borden was the only one to add more options ala carte, especially the outdoor reset option. I really appreciate the flexibility your proposal offers. 4. Borden was the only one who actually opened the boiler to make sure they saw it was leaking etc. Everyone else heard "new boiler", saw dollar signs and that was about it. 5. Borden was also the only owner to come out! Which i think is extra important when it's one of these big jobs where you are not only trying to get the customer set up with a good system, but start a relationship for service and maintainability in the future. Mission Accomplished. Finally, they took tons of time with me explaining how each component would be installed, and a very thoughtful and insightful explanation into why you recommend those pieces. Not at all in a pushy sales way. I'm really excited about our new system and it just so happens today is the coldest day of the year and we have invaluable peace of mind! It also looks like a work of art - the company absolutely takes pride in their craft and it shows.

JJ came out to the house and struck it with my kids and husband. I wasn't home but my husband noted that they all had fun throughout the job. My water heater and water temperature at home has been amazing. What more, I asked him to sign some paperwork and not only did he sign it, he got it notarized and mailed it to my house and when I had some payment misunderstanding (btw, JJ came out again to fix some valve), it was resolved as quickly as possible. communication was top notch. I think I have got me a plumber for life. Thank you Tommy, JJ and Joan. I truly appreciate your work and your customer service.

I did not even think to ask for a rough…read moreestimate over the phone...how much could it be to replace a disposal (Insinkerator V) that costs $80? Maybe $250 on the high end? I got a call from the plumber stating it would be $485 for the job. I told them to forget it, then he started to lower his price. No thanks! I am not dealing with someone that could not give me his best price up front. Here is the kicker, a day later the tenant tells me that she finally figured out how to use the jam wrench and the disposal is working just fine! A good plumber would have unjammed the unit and called to say that it is fixed and the cost is just the cost of the service call.

When I called, the woman who answered confirmed that they would arrive at the scheduled time. She also realized that they had the wrong house number on my address. No biggie. I leave work early to be home in time for the appointment. No one showed up 15-20 minutes after my appointment time, so I called the gentleman who was supposed to come. He told me that he can't make it because "something came up in the office" and said he tried to call me 15 minutes before the appointment. I received no phone call. The number he repeated back to me was wrong. How rude and unprofessional. He wasn't apologetic and told me some BS about not having control over not being able to show up. I would not recommend this company and will not be doing business with them.
