Nedded plumbing service at my home so I called these guys and set up and appointment for today for the hrs of 3 to 4. The hr came and went and went and a no show. I called they didnt answers then I looked up their store hrs and they close at 6pm it was on 515 so i called again on my wifes phone thinking they knew my number and the phone rang twice then straight to voice mail. Im not calling these guys again and i hope u dont too cant relie on flakes and if it was an emergency i cant imagine how angry i would get.

**Update 12/20-I received a text from the owner a few days later apologizing and better explaining what occurred (plumbing old, this is common, they are getting a replacement handle). I appreciate this service recovery and look forward to getting our handle back in service.

I chose A+ waterworks to complete the upper lateral repair on my home. From beginning to end, the job went very smoothly, quickly and I couldn't be happier. Nasser, the supervisor is great and runs a great crew. He handled all the required permits and kept me informed of the steps along the way. Everyone is professional, friendly and works hard. I highly recommend this company.

Terrible customer service. Failed to re-light water heater before leaving and refused to come back out when we could not get it to work properly again. Rates are outrageous. Assessment that was made was negligible at best.

We made a call early yesterday (around 830) about a broken pipe and water leak in front of our home on the emergency line. He took the info and stated he would pass it on and no one ever called or came by. My mom ended up calling back around 4p and was told that they had too much going on. She said they didn't give a real reason why no one came out or called. She felt like they were overwhelmed. He mentioned people and appts but for an emergency line (that we initially called) I would assume those calls are priority.
He ended up saying he would call a guy. Around 545 or so another guy called and said he was in Calistoga and couldn't get to us till the morning.
The gentleman showed up this am and did a great job and fixed our problem in less than 2 hours.
Apparently he doesn't even work for this company. Our problem was fixed and we now have running water with no leak. I am submitting this review because an 830 call with no response on an emergency line is not great customer service. I would have called someone else to have the job done if I would have known that there was no available guys to come do the job all day. And ultimately it ended up with someone completely different doing it anyway, 24 hours later. So thanks for that's

Fantastic service. Nassir(sp?) was right on time, honest and friendly. What more can you ask for? I highly recommend this company.

Job started in January, Nasser said it would be ""at the most"" a 2 day repair and our house sitter would not be inconvenienced. We paid $1700.00 in advance. She didn't have water for 2 weeks, the technician would come at irregular hours, would not call in advance and did not keep appointment times. Holes were cut into the drywall and never repaired. It is now June and the job has NEVER been completed, we still have no water in our kitchen, fine if you like lugging buckets of hot water from the tub to the kitchen sink to wash dishes.. The house is totally covered by a video surveillance system and I have documentation of the coming and goings of A+ Waterworks. I called another plumbing company, Don Nicols Plumbing. They identified the issue right away and will fix, I will expect A+ Waterworks to reimburse me for the $925 it is costing me to have him fix what A+ Waterworks could not.
Horrible, Horrible Customer Service. Nasser seems to have a chip on his back. Even worse poor work. Would not recommend, except to recommend that you run far & fast from this company.
Hello Contractors State License Board. Small Claims, BBB and social media - maybe a YouTube post of the torn up kitchen, holes in the walls and no water.

After a few phone calls to A+, I was finally connected to Mike Nye. I reported to Mike what I thought was the problem on my home fire sprinkler system. He requested that I take some photos and send it to him so that he could give me an estimate. During the process of taking the a second picture, I discovered that the problem wasn't with the fire sprinkler system, but with the water softener system. I thanked Mike for his assistance as my water softener system was under warranty and I would contact the plumbers that had installed the system. A few minutes later Mike called me back and said that he noticed that my fire system gauge pressure was way to high and it needed to be released. Mike did not have to call me back to tell about this and then take the time to walk me through how to release the pressure. Mike went beyond and helped me out even though I did not hire A+ Waterworks. If Mike is the type of people that A+ hires, I would definitely recommend them for any plumbing issues. Thank you again Mike!

I would and will recommend A + Waterworks. These fellows did some back breaking work to dig down to the broken (offset) sewer line. My description is not going to do the work justice.
There were other companies that would not even attempt the job because of possible post tension rods. Undaunted A + Waterworks worked carefully and cut through the concrete in two different locations to not only repair the problem. It wasn't magic, it was skill and knowledge mixed with hard work and sweat. Thank you A + Waterworks, Nasser and crew.

Now 2 years after the job I can tell that what did was not really good. So we rerouted the hot water pipes for the whole house ; it will take at least 5 minutes to have hot water coming out of the faucet . It used to take a few seconds before rerouting . Also cosmetically they did a very sloppy job; as I was told by another plumber . They got the job done really fast ; however, it turned out a very sloppy one .
Please give it a second thought if you would like to start a project with them .
