Can't say enough good things about Alt Plumbing. We've had them out to fix various issues in the past with solid service and reasonable prices. Last week we called again to fix our tankless water heater. Alex took a look, diagnosed the problem and advised us to go back to the installer and have them fix since it was under warranty. He could have repaired it and charged us, but wanted to save us some money. Highly recommend Alex and Alt Plumbing! read more

We had a busted water heater. We were in the process of receiving multiple quotes. John was recommended by another plumber. Came out same day we called to provide a quote. We went with John due to his transparency, great customer service i.e. answered all my questions (had a lot), provided us options and didn't up sell. He and a colleague were able to complete the work next day. Showed up on time. Work performed was high quality and clean. They left the work area cleaner than they found it. Walked us through the various shutoffs and expected system behavior. I'd give them more than 5 stars if I could. Will recommend them to everyone who needs an honest reliable plumber. read more

John was absolutely terrific and super helpful! We called him for a master shower draining issue and because our water bill had been so high and needed leak detection services. He was very prompt, there was no service fee and he fixed the master drain right away. He thoroughly spent time asking questions, looking at every zone on our water irrigation system for our yards and making notes. We found out very quickly that we were wasting a ton of water through a broken irrigation system. He answered all our questions, gave us super valuable information, and genuinely cared about the issue to fix it. I will 1000% choose him and this company every time for any plumbing issue! read more

I encountered a sudden drop in water pressure on my kitchen faucet. My wife and I tried to fix the issue ourselves thinking it was the cartridge that was bad. But we had no success. It was time to call a professional and I contacted Alt plumbing. They showed up on time and diagnosed the problem within 30 to 40 minutes and fixed my faucet. They were easy to work with the price was very reasonable. I would definitely recommend them for plumbing issues. read more

Made an appointment on Saturday over phone for a Monday appointment. Got verbal confirmation from office manager and email confirmation from the system. No one showed up and no one called. When receiving my inquiry call at the end of day, the office had no idea what had happened. Not very professional, in my definition. read more

We have used John on two separate occasions now. He did great work both times finishing the jobs pretty quick and for a fair price. Definitely our go to guy when we have a plumbing issue!! read more

Good service, fast response, price is also reasonable. Richie is the hero guy to provide service to me.

This review mainly covers his flexibility and reliability. I bought some BioClean plumbing cleaning chemical from Alt Plumbing when I thought my drain flies in my masterbath was coming from the sink (found later it was coming from under the toilet). Anyhow, it's good to have this BioClean stuff on hand anyways for regular drain upkeep. I called during a Friday evening just before his place was closing and asked if it was possible to purchase BioClean from him. It sounded like he was going to be busy Saturday but he said he was willing to meet for me to get his product. I met him at San Marcos and he also gave me advice on how to use it. He definitely gets a 5 for a reliability, flexibility, free advice, and communication. Not sure about the actual plumbing work though. read more

Was looking for a plumber to fix a leaking faucet for a rental property that we have and reached out. Got a really fast response and quote, they were even willing to come out on a Saturday. Unfortunate, we have to go through the HOA plumber so I was unable to use there services but they had very good customer service! I hope to get the chance to use them in the future. read more

My pump went out in my sewer lift station and I gave ALT a call at 8:00 PM. My well was full of sewer waste and they talked me through different options of what I could try to do to eliminate the problem myself. After realizing it was a bad pump they came out the next day and installed a new pump and valve in a very timely manner. All the work and customer service was extremely professional and they walked me through tips on how to maintain my lift station to make it last a long time. In all I recommend this company for any plumbing issues as I will definitely call them back if a problem ever arose again for me. The rates are affordable and the quote they gave me is what I paid. I'm happy to say I finally found an honest plumber.....thanks ALT Plumbing read more

After initial confusion over the appointment time (an honest mistake), John came out today and did several supply line valve replacements including the icemaker supply valve which required opening the wall and cutting in new pipe (not unexpected). The work was done professionally, John is a nice guy, clearly knows his stuff, and the price was reasonable. What more could you ask? We're going to have him bid on an upcoming gas line project too. read more

I have used Alt plumbing a few times now on different plumbing problems. I have nothing but good things to say about this company. If you want a good plumbing company call Alt. Ask for John read more

We had a horrible experience with a plumber a couple years ago so when our outside sewer line backed up, we were nervous to call a plumber. Alt Plumbing came right out to inspect and make a repair recommendation. We scheduled the repair for the next day. They were timely, priced reasonably, did great work, and John was a really nice guy. We absolutely would call Alt Plumbing again in a heartbeat. Highly recommend!!!! read more

Probably can't say enough good things about my experience! We had a leak in the garage ceiling which we discovered late on Friday night. I started calling plumbers Saturday morning and spoke to the very friendly and nice Sydnee who said John would be able to get to me that day and gave me a 3 hour window. John was at my house right in the middle of that time frame and quickly discovered the source of the leak in a very tricky, poorly accessible spot. He was still able to to get his hands in there to fix it with minimal removal of dry wall and a lot of dexterity. Coupled with the fact that John is very friendly, knowledgable, professional and efficient...and charged me a very fair price...I couldn't have been happier. I thought I'd need to have the water turned off all weekend as other plumbers were either closed or said they couldn't come out until Monday! I highly recommend John and Alt plumbing!! read more

I had a very positive experience with Alt Plumbing, who responded immediately after a toilet flooded my home. John (the owner) is knowledgeable, direct and honest. Plumbing disasters are traumatic, but when you can rely on a professional to assess and repair the problem correctly, it's much less painful. I recommend Alt Plumbing with no hesitation. Thank you John! read more

Recently had the reason to call Alt on a Sunday due to drainage line backup. First technician spent well over two hours attempting to clear lines in two different clean outs, using a 75' snake. Unfortunately, the blockage was at the curb connecting line and he couldn't reach it. He made arrangements for a different technician to come out on Monday, and did not charge us a dime for the Sunday visit! This is one honest and class-act business! The technician who came out Monday was equally as professional, charges were reasonable, and got the job done. Will not hesitate to utilize this plumbing company for any plumbing needs going forward. read more

I have used John and his company many times. They are pro's and give fair prices.

Alt installed a tankless water heater for us 5-7 years ago. It has been running smoothly ever since. Yesterday, our family returned home after an 8 day vacation. The fridge needed some purging, and, in the process, my husband put some old rice & shredded chicken down the disposal. The double sinks backed up. We have had similar experiences, and have been able to clear it up ourselves, as the clog was local, in the pipes right below the sink, Not this time! After approximately 9 hours of DIY attempts, including two trips to Home Depot, & installing a new garbage disposal (because the current one sprung a leak in the process), we literally threw in the towel! Travis arrived within the quoted time frame, quickly summed up the situation, and went to work. Thankfully, it was an easy fix. Putting too much stuff down the disposal, after a week of our plumbing being only minimally used during the pet sitter visits created a soft clog 30 or so feet from the sink on the way to the main line. He was able to snake the line and resolve the clog within 30-35 minutes of arriving. He also educated me on other things we could check and attempt if we encounter a similar situation in the future! Good people, honest, reliable, & reasonable service fees! read more

John came out same day....so nice to have a good honest plumber on call. He communicated with me throughout the day so I knew all of my options and I knew what to expect. He cleaned out my clogged drains and found roots in my main drains.....gave me some great advice on how we can solve the potentially big issue. I will definitely use alt plumbing again. read more

Fixed the clog and gave me helpful advice on other plumbing issues. I really want to recommend you guys but you were two hours late with minimal communications. I hope that improves in the future. -------------------- John called to apologize for the tardiness and the lack of communications. Also gave me a coupon. Five star customer care! read more

John just installed our toilets in our new home and fixed a leak under our sink. He was very knowledgeable and it was clear we hired the right guy. He took his time and explained everything to us and he is very personable. We feel much better now everything is done. We highly recommend Alt pluming and will use them again. read more

John came to my home in Vista to fix a kitchen faucet. Turns out the problem was a broken washer inside the water line that was clogging the faucet. He saved me a bunch of money because I was able to keep my existing faucet and return the one I bought. He was friendly and his prices were very fair. I would definitely recommend Alt plumbing for your needs. read more

Had some problems getting our new tankless water heater calibrated. It was installed by another plumber. The other plumber called ALT to help and they fixed the problem quickly and efficiently. They have now become my "go to" plumber. read more

We had a great experience with Alt plumbing. Jon came out fairly quickly and was thorough and courteous. Definitelh recommend him.

These guys are amazing. Show up when they say they're going to show up , do good work, reasonable price. I've never had a call back since I've used them. They currently take care of all my rental properties. read more

Thank you so much to Both John and Travis for fixing our plumbing promptly and for having excellent pricing! It's nice to be able to trust a company to do the job right the first time. Genuine good people! Would recommend to everyone! read more

Never had such a great service like this before. Needed an estimate to give to my landlord before I could get work done. A tech talks to me over the phone and is completely honest. The estimate ended up being higher than what is was. They have great hours and were able to come out late at night after I got home from work. The plumber was very knowledgeable and friendly. My kids started talking to him and he was super nice to them and did not get annoyed. It was just an all around good experience after years of trying other plumbers that were usually not that great. HIGHLY recommend them!! read more

My water heater leaked everywhere and I needed a new one ASAP. Alt Plumbing was willing to come out on a Sunday to help me fix my problem at an extremely reasonable rate! It was replacing the water heater that determined that I needed a new water regulator ASAP! My water pressure was supposed to be at 75, but was hitting over 140. No wonder all my faucets were leaking! Even though it was an odd sized regulator, they were able to find it and replace it with no problems. I am very thankful that they found and fixed the problem so quickly and efficiently! read more

So I thought I had an issue with my hot water heater (checked by some else) however it turned out that it was fine and I most likely needed a new cartridge to be replaced in my shower. I checked Yelp and Alt Plumbing had 5 star reviews as well as a Yelp deal. I thought this was a win win so I gave them a call. John was very accommodating and setup an appointment for the next day. The gentleman who showed up (forgot his name) brought the replacement cartridge he thought may fit but it did not so he had to leave and get a different one. He came back and proceeded to change it out. The job didn't take very long and he said I was good to go. I should of asked early on what the total charge would be ($240) because now after doing some research I know I was overcharged even with the Yelp deal ($25 off). Also after taking a shower later that day I realized he didn't set the hot water limiter high enough so I got mostly luke warm water until I personally made the correct adjustment. Now as I look back I could of most likely done the job myself and saved a lot of money. Lastly he said he would email me a copy of the invoice which I never received. I learned a few lessons that day, one of them being not to contact Alt Plumbing ever again for any of my plumbing issues. Beware. read more

We purchased a water filtration system with a water softener. In order for the warranty to be valid, we needed a licensed plumber to install. I originally called a different plumbing company and they agreed to install but when the day of installation arrived, the technician indicated that they didn't carry the correct tool. That same day our water valve (regulator) supplying water to the house broke. Our home warranty company sent two plumbing companies. One could not make the repairs, the other wanted to charge an arm and a leg. Instead, we found John and he was courteous, knowledgeable and responsive. He arrived and gave us a great suggestion about the system. We purchased some additional parts and he completed both jobs for a very reasonable price. We even asked him to come back and make a minor modification and he did so without any problems. He gets an A for communication, knowledge and customer service. He runs his own business and sometimes gets backed up with repairs, but he prioritizes and lets you know whether this will affect your timeline. I would use him again and recommend him to friends. read more
