Recommended Customer Reviews

Tim was the plumber who helped us with our plumbing issue. We are on the bottom apartment and we were experiencing back-up issues with our garbage disposal and our dishwasher. This was our second time experiencing the issue with the back-up and our landlords who live above us tried to put the blame on us. He confirmed that our pipes were also connected to the upstairs apartment and it wasn't necessarily our fault since the line was shared. Tim took the time to answer our questions about preventive measures so this doesn't happen again. He also spent time teaching us how pipes worked which was extremely helpful to understand why things were getting clogged. I can tell just by his explanation that he had a ton of experience and knew what he was doing. Our pipes will most likely get clogged again so I hope he's the worker we get every time.

I've used A T C Plumbing a few times over the years. Again great job. Our garbage disposal died last week. TJ was on time, very efficient and competent. Replaced the disposal with a new one (they supplied) quickly and cleanly. Over 8 years ago they replaced the disposal. The cost comparison this time was: The exact same labor rate and just $20 more for the new disposal. Unbelievable.

My bathtub was overflowing but ATC did a great job fixing it. A lovely lady named Desiree called me to schedule an appointment early in the morning and I got my appointment on the same day! Tim is on time, quick and very professional. He got the job done in less than 15 mins. He is an exceptional plumber!

Tim came out promptly and fixed the problem. The job was done professionally was completed cleanly and at a reasonable price.

Highly unethical business. They want to sell you their stuff which is marked up like 2x. If you bring your own and they say they're ok with this, they either won't install (make excuses) or overcharge to make up the difference. The first time we needed a shower faucet to be installed. The plumber kept saying the one we had didn't fit and kept bringing parts from his truck that just did not fit. He charged for an hour and left. Our friend installed the one we had brought!!
The 2nd time we needed our toilet replaced. We got a top of the line brand toilet for 1/2 the price their plumber had quoted. When the plumber got here, he charged us 2x the installation fee quoted on the phone and charged for more time than he was here. He warned us to buy stuff straight from him next time and said he needed to make up the difference. We would have appreciated it if they were honest up front about the cost and then keep their word.

I have used Around The Clock for my personal home and business plumbing needs for over 15 years. Tim Mateo and his staff are professional hard working people who take care of the problem now! I have always received a fair appraisal of the issue in terms of need and cost and am always offered the best solution. Tim worked on my parent's home in Palo Alto and treated my elderly parents with the utmost respect and care- going the extra mile to help them out. He has also worked in my home, installing water heater and other items in bathrooms. And he and his staff take care of my HVAC system at two businesses I am a partner in, Rok Bistro and Rok Steakhouse.
Around The Clock is the ONLY plumbing company I use- and my experiences with Tim and his staff, both in the office and plumbing techs are the reason why!

EXCELLENT all the way around!!!! Tim is quick and is an exceptional plumber. A real person answers the phone with outstanding customer service. I was impressed!!!

Our 40 plus year old wall heater failed to light. And. this happened just one day before a guest from New York was scheduled to arrive for Thanksgiving and use that room to sleep in! Dillan came out this AM and spent about an hour seeing if a relatively minor part replacement would solve the problem but, no luck. The old heater was shot. Dillan and Tim then replaced this with a new model, cleaned up all of the mess and did it all within about about 5 hours. I was delighted with their skill and and attention to detail.

Tim and his son spent a total of 3 hours or so on a leaking pipe under a bathroom sink and a leaking shower diverter. Neither was fixed. They didn't seem to have a good idea of how to fix those things. They kept trying different diverters and none worked. Also, Tim was very rude the minute he came to our place. I showed him where the leaking diverter is and while he was checking the diverter, I was standing 2~3 feet away from him. Then he threw a pipe wrench at a box next to me. The wrench plummeted onto the floor and almost hit my foot. Instead of saying sorry or anything a nice person would say, he yelled: ""this is my work area, get out!""
I cannot believe a plumber who is so rude and lacks the skills for his job is still in business. There are so many plumbers in the area who are much more friendly and provide much better service. Stay away from Around the Clock!

ATC replaced a toilet even though there are issues with the flange and did a GREAT job.
Plus, they left the bathroom clean too! The brand new toilet had a faulty part which gave up after 2 days but they came out to replace it bright and early the next day after I informed them.
Are they pricey? Yes but honestly I experienced a major plumbing leak after calling another plumber on Yelp who did a faulty job so it's worth sticking with the pros who want to maintain a reputation.
