Recommended Customer Reviews
Horrible, horrible customer service. I was a long time customer of Air Comfort Systems which was recently purchased by Blau. They canceled on me one week and failed to show up the next. When I called to inquire about my service Blau's inept agent, Kathy, was extremely rude. If Blau is so busy that they can't keep their appointments, not to worry, I won't be using them ever again. Take your money to professionals who deserve your business, not the other way around. RIP Air Comfort, you will be missed. Blau, you're the worst
Ernesto R.Stay away. Waist of time. Salesman will arrive instead of the promised plumber. For a rather simple elbow replacement they would charge $619! So I paid him for the salesman assessment $41.18. So if they promise to send you a plumber, expect a salesman. Hope you have better luck!
I called Blau because my tenant was having water drain very slowly from our bathroom sink. Drano had been used on several occasions. Having replaced several other pipes in the home because they were old galvanized steel pipes that become clogged and need to be replaced, I suspected that was the case. Instead of sending a plumber to the home, they sent a ""technician"" to auger the sink, who called me to authorize a $175 charge.
The J trap broke (probably due to the Drano) and they were unable to auger anything, but still charged me $175. They then called me and told me it would be an ADDITIONAL $222 to have a licensed plumber come out to change the J trap (NOTHING else included), which if you've ever owned a home, you probably know you can change it yourself in a matter of 5 minutes and a $7 trip to the hardware store.
When I called their office to ask if they were nuts, they told me the ""technician"" is incapable of changing the J trap, and that they would not send out a plumber on the first call no matter what (they certainly could have made this a little more clear initially). Considering how the initial conversation was talking about a true plumbing issue, I feel pretty screwed by these guys. When I talked to their office about all of this and asked about having a plumber come out after I replace the J trap, they were very hesitant to give me any pricing. I believe Joanie is the manager I talked with, and she told me she was unfamiliar with a J trap and that she couldn't tell me how much anything would be to have anything done after I replaced the J trap.
She finally spat out it would be $30 for every quarter of an hour for diagnostics, and a flat fee based on what was found. I don't find that out of line at all, but what I do find appalling is how they are essentially trying to charge me almost $400 to replace a J trap, with no resolve on the issue that I originally had called for.
Blau installed a boiler for us three years ago. When it began to fail intermittently in Dec we called them thinking they could fix it. First service call- couldnt find the problem- charged my husband 115.00 .Second service call- replaced a gas valve, after first telling us that their ""testing"" showed a bad sensor. The tech didnt have a sensor on his truck so decided the problem was the gas valve instead. Charged us 720.00. Two days later -NO HEAT again. A different tech arrived and told us he thought it was the damper sensor( yet a different part). He didnt have that part on the truck . After consulting with the people on the phone he replaced the aquastat- still no heat. He then disabled the damper sensor. We then had heat but our high efficiency boiler is not working as intended at full efficiency.
The tech called the next day and told us that to replace the damper sensor would cost us another 700.00.
A reliable neighborhood plumber we have used told us that intermittent problems are generally always the damper sensor failing and that this job would quote at around 450.00. So we have paid Blau 850.00 and still have the problem on a boiler that they installed.
At best these guys are incompetent- there are plenty of good, honest, decently priced service people in Milwaukee- AVOID BLAU!
I filed complaints with the BBB- at that point Blau said he would replace the damper sensor for no extra cost. No way would I let them into our home again.
Rachel K.Blau is a bit more expensive than some other companies, but I'm happy to pay the extra for the amazing service from very experienced technicians. Problems are diagnosed quickly and I like that I know upfront how much it will cost me. I have had plenty of shoddy service in the past and it's nice to know I can trust their work. I have been using them for years and have never had the same problem twice.
I can't say that for other companies. I was using a different plumbing company for awhile from a referral and I was charged $260 for a problem they had ""fixed"" 3 months earlier. I went back to blau after that.
I see someone was upset about them tagging all their pipes, etc. in their basement, but I love it. It helps me when I'm doing some DIY projects.
Jane K.theo is a scammer. blau is a rip off.
unfortunately due to my complete ignorance we just paid blau $260 bucks for something i could have done myself. when i called them i even asked that and the response was ""you need to find that out yourself."" nice. i've since called three other major plumbers in town to get advice and estimates (after the fact) and they were all honest and told me i could do it myself! besides that theo went around snooping in the basement and affixed stickers on both my water heater and boiler that i can't get off and hung plastic labels on a bunch of pipes that are going to be a chose to remove. he told my 84 yo mother tat we need a ton of other work done and gave her a proposal for $1000 bucks. for a new faucet! and some other minor thing. i wanted to send him packing but we had already incurred a truck charge plus some diagnostic time. and i didn't have the knowledge for sure to know i i let him go it would be worth it to call someone else.
argh. .never use these guys.
Robert O.Beware of the Blau Plumbing. They are nothing short of scam artists. We had a drain clog in our basement pipes that has been fixed a few times prior all within an hour or so. In this situation the plumber who showed up could not have been older than 21 years old. He started to snake the drain and four hours later the pipes were leaking profusely and the clog was still not fixed. The young plumber to his credit, did take the blame for the additional leaks. However, once he contacted his boss the story changed and his boss gave us an $1800 verbal estimate to fix it sight unseen. In addition, he blamed us for the problem and claimed his plumber had nothing to do with the leaks. The young plumber left without fixing the clog or the leaks he caused. We were forced to call another plumbing company to clean up Blau's mess.
I would definitely stay away of Blau Plumbing!!!
Jerry B.Theo came out to investigate a low water pressure problem I was having. Turned out to be a blockage in the pipe, due to age. He did a reverse flush and it solved the problem. He informed me that this is a tempororty fix, as the pipes do need replacement. This I knew, so it was confirmation. The bill was very reasonable. I am very satisfied.
Christopher H.We had a bad experience with another plumbing company (see my previous review) and decided to try Blau for our broken water heater and rotting furnace. James Blau came out and helped solve all our problems. He was professional and friendly and since I wasn't home at all helped my fiance understand everything he was doing. We no longer have out of date machines and crazy pipes everywhere. We have two top of the line units taking up less space and cleaner (and less) pipes. After almost a week of no water and a lot of frustration we are more than happy with the outcome.
I needed a new hot water heater. Blau gave me an acceptable bid and the installer was there the same afternoon. I Needed a couple of minor upgrades and was given the price up front. There was no high pressure sales and the job was done efficiently and neatly. Everything was cleaned up at the end. I'm very satisfied.
