    They are very professional and honest. They installed a water softener and tank less water heater and did a great job

    Text pg 5

    I had an incredibly poor experience with Flash Plumbing. I don't typically leave a negative review if only one aspect of my interaction doesn't go well. But repeated issues over the course of my experience left me feeling compelled to leave a review I initially requested a plumbing consultation on Yelp and indicated I would like a quote for replumbing my clients house. I'm a realtor helping my client purchase a home. I asked for a quote for supply and drain line replacement. I was called by their office and in subsequent texts we scheduled a 1pm. The texts mainly speak for themselves but below is a list of my grievances: - Scheduled a 1pm which they did not cancel until I repeatedly asked for confirmation. They did not cancel until 12pm - I was asked to send my clients inspection report. I was then given a call and they were attempting to upsell products which we had not requested. All without having actually seen the home. - The lady on the phone abruptly hung up on me after I asked for just a quote on the supply and drain lines as requested (to her credit she did apologize in the texts) - Scheduled a 2pm consultation in which they did not call or even mention until I texted again asking what happened. - Scheduled a 5pm consultation which again did not happen with no call. I understand if they were too busy. Which is why I gave them an opportunity to decline the work so I could find someone else. Overall I spent the entire day only to have nothing done. Very disappointed.

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!

He took the time to carefully look around and figure out what was causing the problem instead of rushing through the job. I had contacted other companies before, but it was sometimes difficult to understand their explanations, and I didn't feel like I was getting clear answers. Johnny was completely different. He explained everything clearly and patiently, making sure I understood what the problem was and what my options were. I also really appreciated that he explained the cost upfront and let me know about things I wasn't aware of before starting the work. There were no surprises, and I felt comfortable knowing exactly what was being done and how much it would cost. Johnny was not only knowledgeable and professional, but also very kind and easy to talk to. He answered all of my questions and made sure I understood everything. I'm very thankful for his help and the way he treated me with kindness and respect. I would definitely recommend Johnny and All City Plumbing & Air to anyone who needs plumbing or air conditioning service. Thank you, Johnny, for your excellent service and for taking the time to help me understand everything!

From the start, he took the time to explain his entire process in detail so I could easily understand exactly what he was going to do. We hired him for a significant amount of work, and he handled all of it flawlessly. He replaced our kitchen sink, garbage disposal, and the angle stops around our bathrooms. He also installed a brand-new water heater, a Flow Tech anti-scale system, and a thermal expansion tank. Additionally, he replaced the main faucet and pipes connecting our house to the city water supply and successfully fixed our home's water pressure, which had been running dangerously high. What truly sets Gabe apart is his customer service. He is incredibly friendly, attentive, and kept in constant contact throughout the entire project. He is completely transparent and never acts like a pushy salesman; he simply assesses the issue, states the exact cost to fix it, and gives you the space to make up your own mind without any pressure. I would absolutely hire Gabe Smith and All City Plumbing again.

I really appreciated their professionalism and straightforward approach and would definitely recommend them.

Second, replace the old waterline leading to the water dispenser with a new one. The plumber stopped the leak but left the old filter and waterline in place, contrary to what the invoice stated. He said he would check with the company about replacing the waterline. The company then proposed installing a reverse osmosis system for $1800, even though I had clearly stated I did not need a new filtration system, only a simple replacement waterline, since the dispenser already has its own filter. It took over two days to get a response, and only after I followed up twice. On the second day I hired another plumber who completed the waterline replacement for a fraction of the cost.

I knew this was the right call to make. I contacted Mr. Castillo and scheduled an appointment for him to come to our home and give me an estimate. Mr. Castillo arrived fifteen minutes early and immediately began looking for the cause of the leak. He was very friendly, professional, clean, and outgoing. Within thirty seconds, Mr. Castillo identified the problem and gave me an incredibly affordable quote. I agreed to the price. As he began working, he discovered two additional issues with the pipes under the sink. Rather than raising the price for the new problems, Mr. Castillo assured me the cost would stay the same, even though it would require a few extra pipes to fix. My first impression was that he was honest. I decided to tip Mr. Castillo more than I planned because of the great price and the extra work at no charge. Mr. Castillo finished the repair in twenty minutes, cleaned up the area, and left it better than when he arrived; my sink was fully functional again. Castillo's Plumbing is now my go-to plumber for any future plumbing needs.
