If you are looking for a reliable plumber, this is it. We had the idea for a custom project in our back yard - which was very complicated. It involved water supply and drain to an outdoor sink, separate washout pan with water supply and drain, hose bib for patio misters, water supply to a hose bib in middle of yard. Johnny (co-owner of the company) came to review our idea and proposed a solution. Throughout our discussion, he was very patient to listen to our interests and offered suggestions as well. After agreeing to the job, Johnny came back to turn our concept into reality. Using quality copper line and connections, he created a custom hookup to the existing water supply for the various faucets and hose bibs we needed. He tapped into house sewer line to install two new drains and vent that were needed. Throughout the project Johnny was careful to confirm numerous details with questions to be sure our interests were met. In the end, I can only say - Wow! Allison Plumbing met our expectations perfectly. The job was done using the best materials and skill. Everything works as expected, and will certainly last longer than I will! We have used a few different plumbing companies over the years. After this experience, Allison Plumbing will be our only go-to company for our plumbing needs. read more

I have used Allison Plumbing several times in the past, but this request I thought would be unusual. A past pool service had broken our auto filler plumbing and never said anything. Now it's time to replace and even the new pool service was a little skeptical about being able to fix it. I called Darrell and explained the issue and asked if there was anything he could do. He came out shortly after our call and evaluated the issues, it ended up being a couple of problems: a corroded valve, incorrectly installed pressure reducer and a broken piece of pipe glued in. Darrell and Jonny worked out a fair estimate for me to fix the multiple issues. Darrell got to work and fixed everything in a couple of hours. Just like the past services they have performed for us, they always leave everything better than it was before, not just a quick fix. read more

Tech was knowledgeable and explained everything clearly.  Work was fast and clean.  He gave me some great suggestions to improve my existing setup (a complex valve system).I asked him to do an additional simple sprinkler repair, and he suggested that it isn't worth paying plumbers' rates for the job.  I ended up finishing it myself in 30 minutes. Allison Plumbing is now my plumber. read more

We are so thankful we found Darrell! Our water heater was really old and died on a Monday evening. We called Darrell first thing on Tuesday morning and he was able to come to our house to replace the water heater that same day. He was so kind, efficient and had great pricing. We will definitely be calling Darrel and his crew from Allison Plumbing again for all our plumbing needs moving forward! read more

On Monday morning, it became obvious that our 12-year-old water heater had died. By 1:15 PM I had four bids to remove and replace the water heater. Allison was the lowest bid. That was good because we have used them off and on for more than 30 years. It had been about eight years since we last had to use them. They arrived just before 2:30 PM and they were gone by 4:30 PM. Everything about it was professional and well done. Many thanks to Aidan and Jonny! read more

Trustworthy and fair. Genuinely good people who I felt safe with in my home. Got a shower valve and drain replaced, gas piping gaped and some leaking drain pipes replaced. Workmanship seems quality and it felt like a good value for what we received. read more

I recently had the pleasure of working with Allison Plumbing, specifically with Darrell, and I couldn't be more satisfied with the service I received. From the very start, Darrell impressed me with his thorough inspection and honest assessment of my plumbing situation. He made it clear that although Allison Plumbing is a small company, they are very busy, which speaks volumes about their reliability and demand. I had scheduled two other appointments for estimates before his, and both companies provided me with outrageous bids. What stood out most was Darrell's transparency. He took the time to explain what was necessary for my plumbing issues and was upfront about what might be needed in the future, helping me avoid unnecessary expenses. If you're looking for an honest and thorough plumbing service, I highly recommend Darrell and the team at Allison Plumbing. They truly prioritize their customers' needs! read more

They were wonderful! Darrell came out and replaced a wax ring and handled some other things as well. He explained everything wonderfully and made sure we understood all our options. He wasn't pushy and when he did the work his attention to detail was appreciated. Her cleaned up really well and best of all he treated it with the same detail as he would if it was his house. I would highly recommend them! read more

Allison Plumbing is just up the street from our house. They are always very responsive and honest, plus the do good work.

Allison plumbing came in, diagnosed my issue, snaked my drains and now everything is working perfectly. I would recommend Allison plumbing, quick, courteous and stands by their work with a warranty. read more

I can't say enough good things about Allison Plumbing! We've been using their services for our apartment building for years, and they consistently go above and beyond. Recently, I was in the middle of a jury trial when a tenant called to report a clogged bathroom. Darrell at Allison Plumbing stepped in and took care of everything--from reaching out to the tenant, coordinating the repair, showing up promptly, and handling the issue, to keeping me informed throughout the process. After the job was completed, he sent me a detailed report with photos for my records, ensuring everything was documented. It's rare to find a business that genuinely cares and goes the extra mile like this, and I can count the number of companies that do on one hand. Highly recommend Allison Plumbing for their professionalism, reliability, and commitment to excellence! read more

Thank you Darryl for the professional repair your company made on our main water supply and pressure reducing valve to our house. It was corroded and in need of replacement. Ken and Aiden also reconfigured our irrigation valve to tie in to the main water supply with separate valves for each. Thank you for coming out personally today to make sure we were happy with the service. We highly recommend your company for plumbing needs! read more

Had a semi severe plumbing clog. First time using this company and we're FANTASTIC! - communicated about timing - friendly - informative about the process. - fairly priced. Will definitely call then if needed again read more

HIGHLY RECOMMENDED! Look no further! Best Service, Price, Communication, Skill, and Professionalism. Needed complete Re-pipe to replace old low quality copper. Darrell, Jonny and the entire Allison Team did an amazing job including complete Copper Repipe, Hot Water Heater, Bath fixtures and all wall/stucco repair. I obtained quotes from 3 Top Yelp Plumbing/Repipe trades. Darrell was the ONLY estimator to walk the entire property, look in the attic, measure and provide solution for a difficult area. He outlined exactly what, when and how they'd perform the work - plus details for smaller items no one else noticed. The Allison Team showed up on-time daily, worked tirelessly until daily scope was met and completed the project skillfully and on-time. Always clean, and with attention to details. Can't say enough good things about our experience. Former Owner Kenny did quality work at a fair price. We're so grateful Allison Plumbing is now in very good hands to continue that tradition! read more

We just got a whole house repipe because our galvanized pipes were corroded and narrowing to the point where the water flow in our sinks and shower were significantly diminished. Johnny and Daryl did an awesome job in every way! I'm so impressed with their attention to detail! I would recommend them to anyone looking for an honest, reasonable and professional company. read more

Just wanted to express my appreciation for Allison's plumbing team. My aunt and uncle in their 80/90's were fretting over a leaked toilet everytime they flushed. I took some time to research local reputable plumbers and found Allison Plumbing. From the initial point of contact with Johnny and the actual plumber on site (Daryl), they were so professional and diligent in ensuring that the job was done right to repair the leak. Daryl communicated with me when he was arriving and every point of the way. He took the time after the repair to let me know what was exactly done and the extra issues he had found and addressed in addition to the original ask to ensure it would be trouble free for some foreseeable future. My aunt and uncle were very pleased and are at ease now having this worry off their shoulders. read more

Exceptional customer service!!! Following two expensive slab leaks under the foundation of my property, I decided it was time to do a full re-pipe. I called Allison plumbing for a quote. I had used them in the past for an unrelated project on a different property and I had been very happy with their work. I submitted a price quote request online and Johnny promptly reached out to find out what was going on. He asked questions about the problem and I shared the history of the previous slab leak which occurred just 8 months prior. Johnny said he could help and the next step would be for someone to come out to assess the project. The following day, Darrell contacted me to say that he would be taking a look at the property to see what could be done. He arrived promptly to the appointment and he took a detailed look at the house. After his assessment, he went over everything with me. He was clear and transparent about the challenges involved in such a large-scale project. I'm a detail oriented person and I ask a lot of questions. Both Johnny and Darrell took the time to answer each and every question I had and they explained things in a way that I could comprehend. There was absolutely no sales pressure at any time, in any way. In sum, both gentlemen were friendly, professional, responsive, reliable, informative and honest. Chances are if you're reading this, you're looking for an honest plumber. Give these gents a call and give them the opportunity to earn your business. Thanks again, Johnny and Darrell!! read more

We were very pleased with our water heater installation by Allison Plumbing and their professional plumber Doug. Highly professional, straight forward and timely every time we have called upon their service. Thanks Allison read more

I am very impressed with the work Doug did on our gas line into our fireplace. We purchased a new gas fireplace insert and our gas line was in the way of the insert being centered within the fireplace box. Doug modified the line by shortening the line. I'd like to add, prior to having Doug with Allison Plumbing do this job, I received a quote from another very popular local plumber. This quote was $400-$700 depending on work involved. When I received the quote from Doug, his quote was $225. After getting into the job and realizing there was more to it than simply cutting the pipe, *I* asked him if the estimate should be modified, he said it should be changed to $350. I agreed and was more than happy to pay this amount. Doug worked hard to make it just right. I'm a VERY happy customer! ~Sandy read more

Great plumber! Shout out to Daryl who replaced my water heater this morning. He was prompt, friendly, knowledgeable and cleaned up thoroughly when the job was complete. I will definitely use them again! read more

Allison plumbing installed a commercial water softener system for us. The staff including Johnny and Darrell were on time (actually early), professional, did quality work with level and braced piping, and were very friendly. I would highly recommend them. read more

I had Allison Plumbing complete a shower cartridge and faucet fix along with a new whole house pressure regulator and a water heater expansion tank. Darrell quoted me a fair price over the phone and set a date for the work. He showed up on time and after evaluating the work in person, decided to do a little extra work to make it better for me. He and Matthew completed the job efficiently and everything looked great. I am very happy with the work and can tell you that you won't be unhappy if you hire this company for your plumbing needs. This is one of the most honest companies I have ever worked with. read more

We couldn't be more happy with Darrell and the entire Allison Plumbing crew. Darrell quoted us the best price, service, (plaster patching*) and equipment (USA made hot water heater) of the three companies from which we received quotes. They re-piped our 2100sq ft. house in two days. These people are hardworking, efficient, on time, PROs! *I have to mention the wall patching. Our house is 75 years old. So, our plaster walls are a bit scarred in areas. I couldn't believe that they actually matched the original walls. THAT takes some talent. We will definitely call Allison Plumbing again, if/when we need work done. We HIGHLY recommend this company. read more

The guys at Allison Plumbing are the best and the only ones I trust to do the job right. We needed a dishwasher and a water softener installed. After coming out for a quote, we were told that the old galvanized pipe for the water intake would wreck havoc on the new water softener and recommended we replace that too. A quick internet search confirmed galvanized pipe + water & time = lots of rust. Our TDS results were pretty high as well. Once we were ready to pull the trigger (waited 3+ months for the dishwasher to arrive), things moved quickly. Installation took 3 days and was very professional. We also appreciated that they were never pushy and offered a few different solutions. Highly recommend. read more

My coworker recommended Allison plumbing to us. They did excellent work on our home. When we needed plumbing work for my mom's house I did not hesitate to use this company again. Johnny is very knowledgeable and made sure the job was done right. read more

Allison Plumbing to the Rescue Again!! Yesterday I had no hot water; today I do. Call Allison Plumbing for all of your plumbing needs. They will give you an honest answer and a fair price. Their number is (909) 987-7721 Thank you, Hutch and Dominic! ps. I never call anyone else. That is how reliable they are. read more

This was the best experience I've ever had with a plumbing company. I first spoke with Johnny. He was super attentive and responsive and got me on their calendar right away. Darrell ended up coming to our home to replace our water heater. He knocked it out and communicated throughout the whole process. He was super clean and left everything extremely neat and tidy. I cannot recommend them highly enough! read more

Allison Plumbing has remodeled two bathrooms for us. They came in at the budget planned and in a timely manner. The quality of work is superior. All aspects of the plumbing work properly. Allison plumbers are good at trouble shooting and finding baffling plumbing problems. read more

Allison Plumbing replaced my aged natural gas water heater with a similar make/model. As soon as they completed the job our household started smelling nauseating fumes. Over the course of approx one week, Allison Plumbing's reporting technicians and two of their older higher-ups said the smell was "normal" for a new unit. The gas company came out three separate times and red-flagged it for 'not venting properly'. However, Allison Plumbing and its agents continued to proport the smell was normal and repeatedly turned the water heater back on without making any related repairs. They refused on multiple occasions to help. They eventually re-installed my old water heater upon my request. I went with another licensed contractor who actually volunteered to take the time to find the source of the problem: low and behold the exhaust vent piping located slightly beyond the indoor drywall was partially disconnected (construction defect). I hope they haven't told anyone else who experienced a similar situation that toxic odors like that are NORMAL. Get some training! read more

Allison plumbing to the rescue again!! They did a whole house repiping for my rental house 3 summers ago and did an absolutely fabulous job. Well, this morning at my rental I was having a sewer line blockage problem and the home warranty was only (sorta kinda) fixing problem. Emphasis on the sorta fixing.... so I reached out to Ken and he was at my property within an hour and gave me a true diagnostic and a planned final solution to the problem. He and his crew were back within two hours and cleared the line all the way to the street with a follow up in two days to install a clean out and run the biggest blade possible to clear out any and all issues with the line...and with a warranty should any problems occur again. Allison Plumbing to the rescue again. These guys really are "The One Call To End It All" problem solver. Honest and virtues to spar read more

We have been with Allison Plumbing for many years. Had an emergency leak a couple of days ago. They came to our house and fixed the problem immediately. They left the area clean and took the refuse out with them. In the ten or more years we have used them, we have never been disappointed in the service, or the price. The price was more than fair for the job they did. I would never hesitate to use them for any plumbing problem, even the little ones read more

One star for showing up but late. Then whining about the install until they gave up and didn't want to continue after strewing up the installation of the Roman tub. The scope was only an install with the fixtures already purchased. Then they with took one of the install parts from the kit so I have to reorder that. N return phone call to discuss what their installer did. Shame he was so negative. I can't recommend a company that just don't give a shit. read more

All around great experience with Allison Plumbing! Rebecca was friendly and got me on the schedule first thing the next day. Doug arrived on time and quickly figured out the problem. He took the time to explain exactly what he was doing and fixed the issue quickly. And he is a heck of a nice guy!! Excellent customer service and a fair price. I would not hesitate to recommend Allison Plumbing. See you on the softball fields soon Doug read more

Where do I start? It's all good stuff I swear. So here's the deal, I do room rentals in a five-bedroom house. That means A LOT of people turnover and bathroom use. I am a single, female who knows little about the ins and outs of plumbing products and services. I also HATE to be taken advantage of. I reached out to Allison Plumbing because I see them all over my neighborhood and have never stopped working with them since. My go-to guy Doug feels like I'm calling a favorite uncle over to help me with a plumbing emergency. He's SO friendly and somehow dispels my anxiety with his experienced assessment and quick work. Between how fast the home office and their service guys respond and repair, I can't imagine why I would go anywhere else. Honest work for honest price. Thanks so much folks! read more

They perform work without discussing the price and i got a quote on the phone for one thing, they came over without the part and wanted to charge me the same amount as the quote i got over the phone but just for labor no part read more

We are very happy with the job they did for us. We had problems with our kitchen faucet and called Allison to fix it. The problem was beyond what we originally thought and they went WELL ABOVE what they needed to do to fix the problem. They did a great job. Our plumber was very prompt, courteous and answered all of our questions. They are definitely our "go to" plumbers for any future needs. We highly recommend them. read more

Allison Plumbing did a fantastic job replacing my main sewer line at a very competitive price. They showed up on time and for two days working quickly and carefully digging out the broken root infested original clay pipe. Johnny showed extreme caution with the backhoe as he maneuvered around our spa digging the trench that exposed the old pipe. Devin did most of the hand digging around mature tree roots and sidewalks. Kenny supervised the job and even got on the end of a shovel himself. They replaced the old line with beautiful 4" ABS black plastic sewer line which will now never have to be snaked again! We passed city inspection with flying colors. The trenching, new pipe and worksite were immaculate. After refilling trenches and putting back the landscaping it looks like it never happened! So glad I never have to rent or pay someone to snake our root clogged line again! read more

A huge shout-out to Allison Plumbing for their expedient service and friendly customer service and to Johnny the Technician who was friendly and professional. Johnny explained the problem and within 20 minutes the job was done. I had shut the gas line to the water heater a day before and when reigniting the water heater it would not turn on. I was leaving town Saturday so I was stressing and I had called 5 other plumbers who were not available but Allison saved the day and sent out a technician within the hour of calling. I want to say "Thank you, Thank you, Thank you" for saving me. You guys were awesome!! read more

John came and survey my double sink Problem. He had to work to clear the drain. He had to pull out everything that was under the sink and when he finished everything was back exactly how I had it. He also left the sinks shiny clean. Well done! read more

We woke up in the morning to find that our damn water heater had started leaking. Upon further inspection I saw that it was rusted through and needed to be replaced. After calling a few places I decided on Allison Plumbing. Not for any reason other than they sounded nice enough on the phone and I was tired of calling around. I called probably 4 places and all prices were within $50 from each other so they were competitively priced. Or at least not trying to rip me off. I called in the morning and they told me they'd be able to get everything done same day. Perfect! They arrived around the time they said they would and were professional people. I pretty much left them to do their thing and came back to check on things every now and then. They removed my old water heater and installed the new one. It didn't take very long and when they were done everything looked great. They gave me a few instructions, explained a few things and that was that. It's been a little over a month now and everything is working great. Overall I think they did a great job but the missing star is due to the fact that they could have left the work area a little cleaner. No biggie but also not 5 stars. I would and probably will have them come back if I ever need any plumbing service again. read more
