Recommended Customer Reviews

I am giving them 4 stars because I don't believe in giving 5 stars. I have had a recurring plumbing issue with my sewer. 5 years and several plumbers later, no one could figure out the problem. In & Out was reliable, gave me a good quote, and got the job done even when new challenges came up. More than the warranty, I know that they will stand behind their work.
And I was surprised at how well they put back my pavers.
Thank you!!

Fast and clean service for a clogged shower. Would use again.
Thanks for the help!

Our toilet was backed up and needed a plumbing company ASAP. Went on google and In and Out plumbing was the first company that came up. I have never worked with a company so easy and efficient. The job was done the same day. They really sympathize with their customers not working at the moment like myself and gave me a discount.

The worst experience I have ever had dealing with a contractor!!!!
PG&E shut off our gas due to a leak, in a bind this company was on the back of the phone book so we called.... little did we know our shit experience would happen.
We were told they would replace the pipe under the house and all the old ones we needed done. Came here and all they did was run a new pipe from our meter to the water heater.... now why in the world would that cost almost 5k?!?.....
Never once touched under the house. Didn't replace the new pipe to the stove. Nothing...
I just don't understand how a company can get away with charging outrageous pricing for a simple job like this. Basically taking advantage of homeowners.
I wouldn't recommend using this company. Do yourself a favor and find someplace honest.

In and Out Plumbing were referred by Angie's List. The worker they sent, Basel, quickly diagnosed our water heater/heating system problem. By replacing the Auxiliary hot water tank for $850, he told us that our two problems would be solved. That is, poor water pressure and not hot enough water.
After installing the new tank, the water pressure problem was not only not solved, but Basel claimed he never said the tank would fix the problem.
Plumbing problems can be complicated, but when the worker lies to me, that is an even bigger problem.
Do not use this company!

I avoid writing negative reviews, unless the situation is egregious; and this is one of them. Our office had a slow draining urinal. In&Out came out and said that the urinal had to be removed and the drain snaked out for $775.00. Since the solution was so expensive, we contacted Ace Plumbing and the problem was fixed in 15 minutes for a fraction of the cost.

Jose Luis came out to check some problem for my landlord. Told us that we should change the shower head and some pipe needs to be cut from the other side of the shower for $1800. I didn't understand why it cost so much to change the shower head and I don't think Luis explaining the problem if there is any really well to us. Feel like he is just throwing the number out there. I would double check with other services because the quote is out rages and he didn't explain the problem.

We used In & Out to clean out to clean the main sewage line from the house to the street. During the clean out, there was some damage done to our guest bathroom and downstairs due to no fault of their own. The owner came by and immediately had his crew (who are also contractors) repair all the damage at no cost to us. They also waived the initial cleaning fee.
This takes a lot of integrity to own up to a mistake of which they addressed immediately to our satisfaction. Oh, the pipe got cleaned out and all is good now.
I highly recommend them for your plumbing needs.

I called In and Out Plumbing because they were on the Home Adviser for recommended businesses. I wanted my water heater serviced and the technician quoted me $475, he said it cost that much because they run a chemical cleaner thru it to clean out the scales. So I agreed, when the plumber showed up all he did was drain and refill my water heater! Then hands me the bill for $475. Well I'm not paying $475 for a drain and refill, I agreed to a chemical clean at that price! What the plumber did I could've done on my own. Currently in dispute about cost of job with In and Out Plumbers.
My dispute has been resolved and the price dropped to a more reasonable rate!

Had them do a couple of jobs. Thought they were a little pricey, but techs were on-time and pleasant, and completed work quickly. HOWEVER, when I called to report a possible problem with their work my experience was very different. Took time off work for appointment but tech was a no-show. When I called, was told there was no appointment on the books. Owner came out a few days later & told me he would be back the next day to replace some parts. No-call/no-show and when I called I was told they were waiting for parts. I had to call back a few days later to follow up and make an appointment & take more time off work for tech to come out to install parts. Tech did not come when expected; when I called the office I was told he was just finishing up on a job. He never showed. Don't know if the leak downstairs was due to their work or not, but I do feel that they were happy to take my money but didn't care about standing behind their work. Or even just helping out with a problem.
