Recommended Customer Reviews

Used these guys a few years back and I still have nightmares about the whole job. If there was a choice for zero star this would be it.
First of all stay clear of these people, they only want your money and a lot of it, their plumbers are not Lic. Nor do they know what the hell they're doing.
Every plumber had a different estimates and one does not agree with the other and they also don't care if you're happy with the job. They keep sending guys to collect a check, just goes to show that customers are not their priority.
Ever since I've only heard bad things about this company, if you see 4 in a roll one star reviews then it's probably not a good idea to schedule an appointment with them.

Got a quote after they saw the work and it's way overpriced. My recommendation is, depending upon what you need help with, call and see if you can get ah estimate over the phone. This company charged per job, not per hour.

They should rename their company ""In and In"" since they kept returning to ""fix"" their mistakes. My husband and I hired them for a home renovation. Things quickly fell apart. It took them over 3 months to complete what was a 6-7 week job. In the end, they fired the GC who was our job's lead and the company owner took the job into his own hands. We saw improvements from then and appreciated their effort, but it was a day late and a dollar short as this was at the very tail end of the project.
1- They sent unlicensed electricians to do the work unsupervised. Most of it was not done to code. Finally, after weeks of trying to fix and troubleshoot, they hired a real electrician to do the job. Sadly, In & Out refused to pay them and the electrician showed up at our house threatening to take a lien on our house.
2 - They ruined our hardwood floors. They redid the floors 3 times and each time made more mistakes. We finally gave up and In & Out credited us for some of our trouble. Our floors are left with dents from bad sanding, spots of glossy finish, dried puddles of finish, footprints where they stepped in the wet finish, and visible nailheads from oversanding.
3- They didn't measure or check anything before installation. They installed our gasline for our kitchen range in the wrong location 3 times. They installed pendant lights off-center so that one hung over the aisle and the other over the kitchen island. Ceiling lights were not installed in a straight line. They also didn't install our dishwasher correctly which caused mechanical failures a few weeks after they left. I could go on...
4 - Work was not completed in a safe manner. They hacked into posts supporting our house and had my father in law not checked, they would have left it like that. They didn't properly patch the roof when putting in a new vent so when it rains it enters the house (fortunately we're in a drought and are redoing our roof soon). Ducts weren't attached to vents nor were they properly sealed (we had to reattach and tape them ourselves).
5 - Disorganized. They couldn't tell me what was happening each day and would show up late. They mixed their tools up into ours (and in some cases would use ours without asking). They didn't print out the plans and relied on my personal copy.

Contacted this Plumbing Company out of their San Bruno office. Explained our needs and was told they could easily address such. When the plumber showed up, he was a guy from a previously used company who was incompetent the first time we met. He again tried to over sell and simply does not know what he's talking about. HE IS NOT A LIC. PLUMBER.....
When I called the company back and explained the circumstances of this individual, I was told he had many years experience, yet acknowledged he was newly hired.... The owner got on the line and ended up saying ""Well we cannot service you""! Don't trust this outfit! No CREDIBILITY......

I had a pressing need to replace the shower/bathtub valves after they were broken by my tenant. It was urgent to replace them that day. I looked for plumbing companies and found many listed and most of them had received positive and some negative reviews. I decided to call In&Out Plumbing and this was a very pleasant experience from start to finish. The lady who answered the was very courteous and knowledgeable. She answered all my questions and scheduled a visit for that same day. Valentino, the young plumber arrived at the scheduled time. He was very polite and friendly and was wearing shoe covers to protect my carpets. I explained the problem to him and he proceeded to repair the existing valves at no charge. I asked him for a estimate for a more permanent solution and he wrote one up. The price was very reasonable and he also gave me a senior citizen's discount. I agreed on the price and asked him to schedule the job as soon as possible. We agreed on having him complete the job the next day. He came in the next day and proceeded to replace the valves and supporting structures. He left the shower operational, but the tile work had to be done the next day. The next day another young man arrived and repaired the wall and replaced the missing tiles. We were very happy with the job done. My tenant wanted hotter water for the shower so I called In&Out Plumbing. They sent out Valentino again and he came in that same day after having finished with his previous assignment. He was very pleasant again, adjusted the hot water supply and resolved the issue informing me that this could cause burns if used improperly. He did this at no additional charge.
Overall,, this is a very professional company, did an excellent job, and priced it reasonably. Above all that, Valentino and the rest of the people I dealt with are superb, caring and concerned professionals. I highly recommend this company and am very grateful that I found them. FIVE STARS IN MY BOOK!

Just Terrible. They only warranty their work for 30 days. After that, they expect you to pay for the SAME JOB ALL OVER AGAIN, at the same cost. That is Ridiculous. In addition, I had different plumbers from this company - quote me different prices on the SAME JOB in a matter of days. There's no set scale, everything is very random & unprofessional.

These guys are great.They answered their phone, showed up half an hour early, rooted my blocked waste line quickly, and charged me exactly what they estimated. I've done plumbing work before, so I know that it's inherently difficult for a plumber to achieve ANY of these things. This was a small, easy service call, and they did it perfectly.

We used to love these guys. Sadly our go to guy, Manny, left.
This morning we had an emergency. We called them, and they scheduled a time to come. They were within the allotted time, which was great. But we were assigned someone different.
The new guy came in, took a look at the job, sized me up (apparently for a sucker) and quoted me $300... for a clogged kitchen sink. We haggled a bit and since I didn't have much time (it's a saturday), we settled on $250. I had a feeling I was getting ripped off, but given the urgency, I decided to live with it.
Price aside, the plumber came into the house with his boots on (no covers) and to add insult to injury, he had forgotten a few tools. He apologized but wanted to leave for 45mins to go get the tools. We just didn't have the time to spare.
To top it all off, I called Miracle Plumbing (5 stars on yelp) and they showed up almost right away, on time, and did the job for $115. All this without haggling. And their guy, Lonnie, was very polite, courteous, and walked into the house with boot covers without prompting.

I was looking for someone to remodel our bathroom. In and Out was the best! They were very professional, on time, and very friendly. The job turned out great and was done in the timeline they gave me.
The ladies in the office were great, always returned my calls and/or emails.
I would defiantly recommend them to be hired.

Hired to do a sewer later and the job was not done correctly. In fact, they caused damage on the property. POOR workmanship. Another company was hired and did the job properly.
