I had a really great experience with Precision Flow Plumbing. When Esther first got involved with the project, you could immediately tell how much she genuinely cares about her customers and the quality of the work. She took the time to explain everything clearly, answered all of my questions patiently, and made sure I felt comfortable with the plan before anything started. The technicians, Juan and Minor, were amazing and incredibly easy to work with. They were professional, respectful, and clearly very knowledgeable about what they were doing. They worked efficiently, kept the workspace clean, and made the entire process feel smooth and stress-free. What really stood out to me was the honesty and communication throughout the whole job. It’s rare to find a company that combines great customer service with high-quality work, but Precision Flow Plumbing truly delivers. If you’re looking for a plumbing company that is reliable, knowledgeable, and genuinely cares about doing the job right, I would absolutely recommend Precision Flow Plumbing.
Adlon and the crew are there for businesses and homes when other plumbing companies won’t respond. They’re responsive on weekends and always as friendly and helpful on the phone as possible. They will often help you find the most budget friendly way to fix your problem. Worked with them multiple times.
Incredible and Reliable Plumbing Services! No reminders needed here. These professionals excel in their craft and prioritize customer satisfaction. I reached out to them last minute for a plumbing emergency I discovered during a cleaning and junk removal project for a realtor for my company . The realtor was understandably stressed, but upon contacting A.B. Plumbing, they promptly answered, communicated effectively, and handled the situation with utmost professionalism. I wholeheartedly endorse their services!
Unprofessional. Also not 24 hours like advertised, BEWARE. I called for a plumber at night, person on the phone said someone was dispatched and would arrive in 2 hours. I stayed up all night waiting and no one arrived until the next morning!!! At some point, I called back to ask for the status, someone said they would check and call me back. They NEVER called me back. They should not have promised to come if they couldn’t in the first place. Extreme waste of time
We were disappointed with our most recent experience replacing the faucet and under-sink hot water heater in our kitchen. First, I requested an appointment online. The form said we would hear back within a day; we didn't. I called to schedule an appointment, and they told me someone would come by 8-9 AM the next day, provide an estimate, and do the work if I approved the estimate.. After 10 AM, they called to say they had an emergency and would call me back in a few hours with an updated time; they didn't. I called the next day and was told someone would come 10-11 AM; they didn't, and we didn't receive a call this time. I telephoned again and was told they would call back to give me a new appointment time; they didn't. A plumber did come by when I was out; fortunately, my husband was home. The plumbing work seems to have been done well, although a circuit breaker tripped because of where the water heater was plugged in. The plumber took away the old faucet and heater (good) and also the box with the new items, including the documentation and receipt (bad). I asked my husband what the work cost, and he said the plumber said that we would be invoiced, so we didn't get an estimate first; granted, I could have told my husband to request one.
I can’t say enough good things about this plumbing company! From start to finish, their service was nothing short of exceptional. First off, their customer service is outstanding—responsive, friendly, and truly dedicated to helping. Scheduling an appointment was quick and easy, and they arrived right on time, which is a rarity these days! The staff was professional and knowledgeable, taking the time to explain the issue clearly and offering solutions that were both practical and affordable. They worked efficiently, ensuring the job was done to the highest standard without cutting corners. What really stood out was their reliability—every detail was handled with care, and there was no mess left behind. If you’re looking for a plumbing company that is dependable, skilled, and truly cares about their customers, look no further. This team is superior to none, and I would recommend them without hesitation! 5 stars all the way!
They get an extra star for coming out quickly to do a quote but that is where it ends. Originally was told I would receive a quote on Tuesday followed up on Wednesday with a text and received a response that they will get back to me on this. Followed up on Thursday with another text and no response and then a phone call on Friday and left a voicemail. Perhaps something happened with my point of contact, things happen and I get it and will adjust my rating based on how they follow up, the ball is in their court. Follow up: I received the quote over the weekend. Unfortunately the quote only covered 1 of the 3 things I asked to get quoted. I followed up with them to update the quote, which they did promptly this time around. I decided to go with a different plumber, to many issues right off the bat with this company, maybe they had an off week!
Our home is below grade, and thus has a plump to pump everything up to the sewer line. It stopped working, which means everything was backing up into the bathtub, which means it's time to panic! (gross! lol). The guys at AB Plumbing came out, and were like "we've never seen this kind of pump before, but we'll poke at it and see what happens". They took the pump apart, piece by piece, and i even heard them call the pump manufacturer and go over details of the pump, and then, not an hour and a half later, they got it working perfectly again. They were super friendly and communicative the whole time, too. Such nice guys! i can't recommend these folks highly enough. They're amazing. i hope i never have a broken pump again, but if i do, i know exactly who to call! Thank you guys again, you're awesome!
Basilio and his crew did a FANTASTIC job... ...sure, he's brief and "to the point", which I don't mind at all.... ...but again, they were perfect. We had a non-emergency situation, which required a trench less approach... ...which, if you haven't seen done before, is really cool. Our line ties in with the neighbor, and we share from the wye out to the main... ...while the hold was dug, the neighbor decided to have his portion replaced as well, and Budget sewer did not mind this scope creep AT ALL. Finally, they lined the pipe from the eye out to the main, providing the neighbor and I a brand new line from homes to sewer main. Would I recommend AB Plumbing? ABSOLUTELY!!! These guys are top notch, and if you end up using them, I hope you receive the same quality service.
We recently discovered a leak in our main pipe after noticing our water bill had suddenly increased. We found out it was the main waterline from the house to the street. We called around and received three different bids, and Precision Flow Plumbing stood out immediately. Not only were they the most reasonably priced. Their communication and responsiveness were exceptional. They came out quickly, were very attentive throughout the process, and did a beautiful job installing the new copper pipe. Finding honest, reliable plumbers can be difficult, and some of the other quotes we received were honestly outrageous. Precision Flow Plumbing delivered excellent work, great value, and professional service. I would highly recommend them to anyone needing plumbing help.
John came out twice to help me out. First was a clogged sink drain in an apartment with odd plumbing that made it tough to snake. He was diligent, respectful, timely, professional, and took the time to explain to me what was going on and what the process would be to fix it. He took care of me, and even went out of his way to clean up mess from the original back-up. His prices and estimates were fair and accurate. I was really happy after this experience and had him come back to fix a broken shut-off valve. He lived up again to the work he did the first time around - timely, diligent, and helpful. Based on these experiences I'm very confident about working with AB in the future.
I hired A-1 to snake my water line that was backing up into the garage, they were fast a d did a good job. It was $500 for the service ]]however they should have checked the shower in the garage as well.After they left that evening we discovered the line was backing up into the garage shower so we called them back..They refused to return u less we paid another $500 they said on e they left the job the case was closed and they did. Not warranty their work. Il Ne er work with them again they did not even offer a discount.
My experience with AB plumbing was day and night with another plumbing service I used several months ago for the same issue. They were responsive/fast, upfront about the costs (and added fees for service on a Sunday), quickly diagnosed the problem and resolved it in under an hour. And they cleaned up the bathroom after (had to remove my toilet to fix the clog). Great service, knowledgeable and fast. Maybe on the higher end for pricing but worth it for the quality of service.
Gail H. Over the years my husband and I have had AB Plumbing help us with several plumbing issues--some big (like fixing the water line to the main), some small (relighting the pilot light) and for other things in-between. In every instance we were pleased by the quality of the work which was done, the professionalism of the group and the reasonableness of the cost. Kudos to everyone! I would definitely hire the firm again.
Had AB plumbing do an open wall estimate to find a leak that had been going on for weeks. They offered different options to address the issue and after carefully explaining it to me we decided to start with the cheaper suggestion and work our way through. Problem was found, fixed and I felt that the communication was amazing and the price was reasonable. Would definitely recommend and be using them again.
