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.

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.

Kenny and his team are the wonderful! We needed an old heater and gas line removed, and a new line put in for a gas range. They were in and out in a couple of hours. Plus (note to wives), the first thing they brought into the house was a vacuum cleaner! They had to cut into walls to do their job, but they left the site just as clean as they found it! Kudos to the Allison Plumbing team!

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

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!

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.

(Rather Late Review) Doug was tremendous in fixing my Wide Set sink having a minor leak. Apparently had a unique cartridge as he went the extra mile and attempted to source one through his local connections, sadly to no avail. Once I located the sink manufacturer and received the parts, they were quick to get back to do the installation. Doug was knowledgeable in his explanations of both what he was doing and what he would need as well as patient. Really exceptional work especially during these times. As a recent homeowner, I felt comfortable and fairly charged. Would highly recommend.

Had a toilet that was leaking from the base as well as a sink faucet that was leaking. I called Allison and they sent Doug over first thing the next morning. Aside from needing to run out a get a less common part that he didn't have on hand, he got the work done in a timely manner. After fixing what he assessed was the problem with the sink, he discovered that the repair didn't stop the leak and advised to replace the faucet. I understand these things can happen - he tried to do the most obvious and least expensive repair which turned out to not resolve the issue. The toilet is good, but because he wasn't able to fix the problem with the sink he reduced the price, which I appreciated. Gotta go pick out a new faucet now and will probably call Allison to send Doug back to install it. He is a very nice guy, knowledgeable, and efficient, and I would rather not have to take up my husband's time to do it himself, not to mention I want to ensure the installation gets done right the first time.

We hired Allison Plumbing (Ken and his crew) for a total repiping at my Moms house in Baldwin Park towards mid July 2020. These guys not only knocked it out in the alloted time but their work was impeccable!! Besides ALL the workers being respectful and professional, the thing that impressed me the most was that Ken was right there on the job working hand in hand with his team! We interviewed several Plumbers, but these guys are far above the rest. Thanks again Ken for a job well done and for restoring hot water to my Mother again!
