These guys suck. Had an emergency on a Friday night and called them 3 times. No call back nothing. DO NOT CALL THESE GUYS. CALL SOMEONE ELSE. Will never call them again. read more

These guys stopped by our complex around 8:45 PM to check something in a neighbor's unit. They were absolutely blasting music from their service truck parked in front of my patio. The employees around the truck were hanging off of the parking awning cover listening to music laughing and yelling loudly. I would normally just consider it obnoxious behavior and not feel the need to note it but I had put my daughter to bed minutes prior and they were so loud I could hear it in her room with white noise turned up to max. Unbelievable. Pretty sure I heard one of the guys mention something about Percocet. I would stay the hell away from this business unless you really want to pay to have the most immature delinquent loser dudes you remember from high school to come touch anything in your home. read more

Scheduling with this company was extremely frustrating. They failed to show up as scheduled and showed a complete disregard for other people's time. If reliability matters to you, I strongly recommend continuing your search for another plumber in the valley. Based on my experience, this company is not it. read more

One night last week I had a shallow lake in my kitchen and dining room from backed up drains - soooo fun! (Insert sarcasm) I called Diamondback and they responded almost immediately- Gary S arrived and literally saved the day! He figured out the issue, was super efficient and was so nice too which made the whole experience better. I will definitely be calling them for all my plumbing problems (even though I am ever hopeful I won't need to) read more

Absolutely worth it! We called for a leaky bathtub faucet, nothing else. These fellas though, also fixed our hot/cold and didn't say a word about it. The last time we spoke to anyone about this tub we were looking at at least 1k estimate, going to to the wall from the other side. If we have any other plumbing issues come up I know who I am calling! read more

I had 2 toilets that were leaking (things always happen at once). I called around 8:45 this morning. I was told my information would be sent to the field manager and he would call me to arrange things. It's almost 1:30 and I haven't heard from them yet. After waiting about 35 minutes for the call I decided to call someone else. Now at 1:20 the job is done by their competitor and still they haven't called. There's no sense in calling these people, they don't care. If you need a plumber and have lots of time to kill go ahead and call these people, but if you want to be treated right call someone else. read more

We discovered a leak around the flooring in our house. After checking with friends for referrals, we called Diamondback first. Sam and Dylan were at our house within 40 minutes of my panicked phone call. After listening to the troubleshooting my husband and son-in-law had already done, they asked us if we were comfortable letting them cut into the drywall to check one spot before they had to give us a quote to check multiple places in the house. We said yes, go ahead. And that was exactly where the problem was! Within an hour of their arrival, the pipe was replaced and completely fixed, and we could turn our water back on! Sam and Dylan were so courteous, and I can't emphasize how much I appreciated how they listened carefully to what we described. They were thorough, completely professional, and very careful about how our house was treated. Diamondback will absolutely be at the top of our list for plumbing issues in the future if they arise again. Thank you for sending us an outstanding team to solve this water problem! read more

We reached out to Diamondback as we were having a hard time finding a plumber that could take care of a rather large job. We had a major leak in the pipe that connected from the street meter to our house. It was the old polybutelene piping. We were hoping to have the entire pipe replaced as this material was recalled years ago. We got turned down from multiple plumbers as they did not want to take on such a big job. The front office staff was so kind when working to schedule our appointment. We got a free quote from Chad and he got us on the schedule within a couple of days. Dane showed up promptly on the scheduled date, dug a trench in our yard to re run the new piping and even moved the line so that it would be more convenient and help us save some significant costs (we would have had to tear up our whole driveway). Dane and his teammate completed the job in two days as we originally anticipated, cleaned up any messes and educated us on the new lines run. We are so thankful for Diamondback as they saved our butts. They did quality work and within budget. Highly Recommend!! read more

I manage a commercial building and contacted Diamondback Plumbing for an estimate. Four days later I am still waiting. Find another plumber.

I paid $250 for a camera inspection on my sewer line to assess the orange berg plumbing at my house. I wanted to have the inspection completed and get a quote for replacement or any other suggestions the company had prior to renovating my backyard. When I originally contacted the company, they were prompt and pleasant to work with in scheduling an appointment. Here is the sequence of events: 1. June 2021: Initial appointment and payment of $250 2. Never received the video or any quotes for additional services, despite verbally discussing with technician 3. I contacted the company, who told me "the camera inspection has a data corruption file" and they'd return to redo the inspection at no charge 4. July 2021: Second appointment for inspection 5. Never received the video or any quotes for additional services (again) 6. August 2021: Contacted the company several time requesting the video - we went back and forth several times throughout August and September. I was told they "have not been able to get all of the USB drives in yet. If I do not receive it the next couple of days we will touch base again." 7. After ZERO contact or reply, November 2021: Asked for a refund, as I did not receive any of the services I paid for Since then, I have attempted several times to work with the company to get the services I paid for OR a refund. They replied ONE time, only when I threatened to report them to the BBB on Feb 15, 2022. Since then, no replies again. I understand that many businesses are busy right now and understaffed. I am simply asking to receive the inspection I paid for or receive a refund. I am shocked to find the company's business practice includes having people pay for things, delivering nothing, and then ignoring them to hope they forget. I've tried all reasonable efforts to communicate with the company to rectify the situation and have had no luck. read more

Our AC unit of 15 years decided to quit on us. We have used Diamondback plumbing multiple times for other projects so we gave them a call. Omar came out and inspected everything and gave us our options. Due to the age of the unit and the cost of what the repairs would be we decided to look at replacement. Omar and his team gave us 4 different replacement options so that we could determine what fit our needs and our budget. They also discussed financing options if needed. The Diamondback team was able to install the new unit within 24 hours and it is working fantastic. We got a great warranty and feel confident that if we have any issues that Omar and his team will be right out to help. If you need your AC serviced or if you are up against a replacement give these guys a shot!! read more

Had a small leak under the garbage disposal. They came out quickly as scheduled. Quickly responded and were up front with the cost. The technicians were very professional and polite will definitely use again if I need services in the future. read more

I had a slab leak at the house and called out two companies. One was a popular, well know company in Phoenix and the other Diamondback Plumbing. The popular company came out and provided a quote and scoped the line. Next in was Diamondback and their proposal was three time less. Literally THOUSANDS of dollars less!!! Please call Diamondback first and don't look back. High quality at a fair price. read more

Called for my friend and this place is amazing! Derek the HVAC tech was very knowledgeable and went above and beyond to make sure our recurring AC unit was solved. He went into the attic to inspect and make sure that there was not any shorts causing the part to prematurely wear out. Thank you for the prompt and detailed service. read more

When I needed two outside water faucets replaced and also had a small leak in some pvc pipe, Dane came to the rescue! He was very professional and understood my situation. (Dire, haha) Thank-You again, Jeff Jarman read more

The old toilet in one of my bathrooms was slow to flush and starting to leak at the bottom. So I decided it was time to replace it. I ordered a new one-piece dual flush toilet from Amazon and had it delivered to Diamondback, then scheduled an appointment to have it installed. Two guys came out and had the work done in only about an hour, plus they put in a new shower head for me. I have used Diamondback for several jobs now, and plan to call them in the future if I need help again. read more

We have a Whirlpool Hot Water Heater that was installed with a 10 year warranty in 2017. In fairness this company did not install this equipment in 2017. This past weekend 9/24/22, the water heater quit. After determining that we did not have hot water due to a fuse issue, we called Whirlpool for Warranty coverage. "WHIRLPOOL REFERRED" us to "Diamondback Plumbing" and issued an authorization number. My husband called the Diamondback on call technician. He stated we do not have Whirlpool parts. Therefore, we will call you back on Monday to have a Tech come out, diagnose the problem then order the parts. Monday came and went, NO RETURN CALL! REALLY!!! The least this company could have done was to call us back and state they were not interested in doing the repair! read more

I usually don't write reviews but my situation seems warranted. The plumber Daniel came and smelled like cigarettes (the whole area he worked in smelled of cigarettes for hours after he left). He had headphones in his ear the entire time. He didn't measure the part he needed and left the house 3 different times cause he got the wrong part to fix the leak. He was not personable and barely announced himself when he entered the home. He said he was only charging me for 2 hours of time but he invoiced me for 4.5 hours. read more

We had an appointment scheduled for a technician to give us a quote for a repipe of our home between 10am- 2pm. No one ever showed. Then I get a call at 3pm (after I had waited around all morning) asking if the plumber could come by at 4pm. I said that would be fine. I waited at home patiently, and AGAIN, they no showed. This time no call, nothing. Wasted my entire day waiting on this company. Too bad they aren't reliable. They missed out on a big job. Moving on. read more

Called them for leak around base of toilet, upon arrival pulled toilet and there were roots all around the flange and base of toilet. They pulled all roots out of the and put new wax ring and reinstalled toilet. No toilet leak but the toilet was wobbly when you seat . Everything was done less than 20 minutes and I was charged $370+.. they forgot to give me invoice . they send me invoice return back and fix the wobbly toilet, they found another problem in the toilet kit and they charging us again. I think the charge was not reasonable. read more

I've had a problem with a toilet they installed, with moisture around the base. However I was unaware of it. I had issue with something else. I called another company experts on drains. That outfit wanted me to spend 3000 for a problem that did not exist. I called Justin back for a second opinion. He corrected the moisture issue with the toilet. It was a great relief. Diamondback is an honest outfit. I'll call them anytime I have a plumbing issue. read more

This company is a rip off. The guy came out, was rude, told me they're "$175 an hour" and then went to his car, came back, said he called his supervisor and they charge "by the job now and it's $600." Didn't explain anything and wasn't very friendly unfortunately. read more

Last month i had them install a tankless water heater. Installer was nice and informative and seemed to do good job on installation. However, they did not clean up though i had left 2 vacuum cleaners near their reach. So 15 min of my cleanup afterwards, But then I put my pickup i n the garage when they left. They had parked next to garage with their van open to do the work in garage. Next day my tire had a screw in it which probably was left by them....cleanup again? I called them and they did not seem to interested in my problems. So i spent another two hours to get tire to Discount and then put on again by myself. Be aware. read more

The person that took my call was very nice. She asked if it was an emergency and I confirmed that it was not. So, we scheduled an appointment for 2 days later at 9am. 9:30 came, and I called to verify that I hadn't written the appointment down wrong. She verified that I had an appointment and said the tech was running late. She said he would be calling me to give me an eta. When the tech called me he had no idea about the appointment. He asked if it was an emergency?.... I said no. It's not an emergency, I have an appointment. He said, "well my friend, I've got 12 emergencies in front of you". I think he thought it was funny for some reason. I hung up and called another company. There are plenty of plumbers in the Phoenix area. Call one that's dependable. Not these people. read more

We needed emergency service to repair a leaking pipe in our attic! Diamondback Plumbing was so quick and kept great communication with us. Levi is the plumber that was sent and he did a very thorough inspection and repair! Great attitude and so helpful. We found their prices very reasonable! Highly recommend this company! read more

Do not try to use for emergency services after hours. They tell you an on call tech will respond within minutes and they don't. Waited hours and no response for emergency service. They obviously don't have the bandwidth to keep up with emergency calls so I would not waste your time. read more

Diamondback did a great job with seasonal service on my roof AC/Heating unit. I have used them for AC/Heating and always been satisfied. Price was great, service technician was professional, through, and prompt. Arrival window was 4 hours but they send a message about 20 minutes prior to arrival. Thank You Tyree. read more

We had 2 different plumbers here with NO success . Diamond plumbing was our last hope. We had both showers backing up and one company told us we needed to excavate our mid century modern concrete floors to get to the plumbing and their bid was around $15000 . Two awesome Diamond employees came in, and within 15 minutes solved the problem. Never call anybody else. Always Diamond.. read more

We developed a plumbing problem at our business at around 9 AM and Diamondback Plumbing showed up in the time frame they promised and fixed for a fair price. I will be calling them back for another job we will be needing. read more

Steve did get in touch with me and apologize for not being responsive to my initial request. I always appreciate it when someone owns up to their mistake. We rescheduled to get an estimate for the addition of a gas line to our kitchen for a new gas stove top. The service representative who came to our house was friendly and professional.Their prices were fair but we decided not to go ahead with the work at this time. read more

Disappointing. My 4 year old AO Smith water heater began to leak gas, so I called over the gas company. They used their magic wand detector and told me it was the regulator that went bad, something that was under warranty. Since I am new to replacing water heaters I called AO Smith and they sent a new regulator and recommended diamondback on their site. After a missed appointment and a delayed one a day later they showed up, replaced the entire regulator unit and discovered only afterward that it was just the gas hose that was leaking. My issue with them is that I told them I "suspected" it was the regulator. As a professional company, I would imagine they would test this theory and do their own troubleshooting, unless of course, they wanted the much larger service fee for the regulator, which I suspect. What makes this even worse is 1. They charged me without testing what was wrong for the larger issue, 2. Didn't have a connector hose so I had to buy a $30 dollar part, 3. Told me to install it, and 4. Took the other good part away, probably for resale. I would have expected a great company to outperform their customers expectations by determining the issue first before replacement and then shipping back the part to save AO Smith money on a replacement nad the customer money on an unneeded service charge for a part that was not bad. Oh, and not expect a customer to fix their own water heater when that is what they were called to do. read more

A clogged toilet that I couldn't plunge or snake out myself is bad. But when it happens the night before my parents are due to arrive in the morning to stay at my house for the week, it's really bad. I called a few places first thing in the morning. Most couldn't get me in that day. Some would come out, but would only do it after hours and would have to charge extra. But Diamondback was able to squeeze me in during a 1:00 to 5:00 window. It was also the only company willing to give me a ballpark figure on how much I should expect to be charged for the job (Every other place would only tell me that there is a call out fee that would be waived if they did the work, and the plumber would determine the charge on site). The plumber came in the middle of the four hour window I was given. Unclogged the toilet in just a few minutes. And then gave me a discount since the job was so easy and fast. He probably wanted to insure that a first time customer would definitely give them a glowing review, recommendations, and use them again. Guess, what? It worked. read more

I used Diamondback Plumbing for a slab leak repair a few years ago and they were awesome. So we called them again a few weeks ago for a leak at the kitchen sink and again this morning for a massive leak in our front yard. For the kitchen sink leak, a technician was out in a couple hours on a Saturday, and it was within an hour or so for this emergency with the main line leak. These guys are reasonably priced - even for an emergency call - and they do really good work. I will continue to call and use them when in need of a plumber. Reliable, quick, and affordable companies are hard to come by! read more

The technician showed up and was able to get to work to find the issue in our front yard. Within 1.5 hours he fixed the main water line to the house and he was efficient and professional the entire time explaining what he was doing and how the device would fix the issue. Great job!!! read more

The ones that tackle the tough jobs. They come out right away. My remodeled kitchen they disconnected reconnected and also had to modify a gas line. Levi, Justin and Joe did great work. Justin stayed late to finish his big portion because he knew he wouldn't be available the next day and didn't want anyone to have to finish his work. So responsible. I like using a team that can do it all and charge a reasonable amount for their expertise. I refer everyone to them and have had the same feedback as everyone appreciates their skills! read more

Had my toilets overflowing about 2 weeks ago. Guy came snaked the washout areas for about 10 minutes problem solved. Now same problem again called a different company to come this time. Looks like the diamondback plumber simply pushed the blockage down the line to temporarily solve the problem. Waste of $150. Don't recommend read more

We called Diamondback Plumbing to fix a slab link in the suspected area on a bathroom. The technician came out with the sounding equipment and identified where he thought the leak was. To verify he cut into one wall and cut the hot water pipe coming from the manifold into the bathroom and then kitchen. He reworked the hot water pipe manifold so we could have hot water in the rest of the house. Before going he stated that they would get us a full repair quote the next day and get us on the repair schedule since we had no hot water in the kitchen. The next day by noon we had no quote or phone call. We call and was told that it normally takes 1 week to get a quote. We explained the situation and what was told us. We were told the technician was in classes for the next few days. After we talked to a supervisor, he got us a quote. However that afternoon we found that there was water leaking into our garage from the wall the technician worked in. We called and left word that we were having leaks. Next day, no word from the company so we called and emailed the supervisor and advised of the continuing leaks and our disappointment. Now 3 days later and more leaking, still no communication even though we paid for the preliminary work done. To solve the temporary fix, we had another plumber come out. He determined that the original technician did not put a cap on the cut line and the water is backflowing from the kitchen sink cold water through the hot water line when the faucet is turned partway hot. So we are not several hundred dollars out of pocket with no communication at all from Diamondback Plumbing. I'd avoid this company and wish there was a way to get all or part of our money back. read more

Contacted them to have an AO Smith water heater repaired. They are even on the AO Smith directory for authorized repair centers. They sent a tech out and the tech said he needed to get in touch with AO's tech support for assistance to help diagnose the problem. However the tech support was closed. So the technician said their is nothing he can until Monday when tech support opens. I was told to call the office to make another appointment for Monday for the tech to return. The operators answered (btw their operators are all very polite and kind) and they transferred to the supervisor on duty, Joe. I asked Joe if I was going to be charged for today visit. Joe replied "yes" and "people don't work for free" and "did he not come out their to fix your water heater?" The tech only made a call. Did not even try to diagnose the problem because he did not have the knowledge to do so without tech support. I would assume a company that repairs AO water heater would also know that the tech support is closed on the weekends if that is how they normally operate. They could have saved themselves a trip if they knew their technician would need tech support. I called up a different plumber on the AO list and he knew exactly what was needed to be done and had it repaired the same day. I do not recommend Diamondback Plumbing read more

I couldn't be more pleased with the level of service, care and quality work overall from DiamondBack Plumbing. My water heater broke early AM yesterday and I called this company to provide an estimate over the phone based upon the type, size, location and what needs to be done. Their estimate was below other competitors by hundreds. Taking into consideration quality of material! Spoke with Chad for the estimate and information and he was very professional, taking time with me to explain everything and recommendations. Then filtering out other companies I found Diamond back to be the best. With that, I had a plumber (Matt) come out just hours later that day. He also was onsite to provide a more accurate quote and was within the parameters of what I was quoted over the phone. He too took the time to explain anything I needed or wanted further clarification on. He too was very professional, extremely polite and friendly. Outstanding customer service, knowledge and experience. From now on these guys are my go to company for all my plumber issues! I couldn't be more pleased overall. That's what you call same day awesome service, excellent price, and fantastic quality of material. Broken water heater 7am. Called DB by 8am, plumber (Matt) at my house by 3pm and fixed within a couple hours so that our family had got water. Thanks DiamondBack and all your fantastic employees and service overall! You earned my loyalty for my family and definitely recommending your company to others needing help as well! - Tyler B. read more
