Best in San Jose CA

Great response and work. Price was also very reasonable. Character minimums on reviews are annoying and a waste of $&! time.

We hired The leak Detection Company to find a water leak in our concrete slab house in Redwood City when other company was trying to brake concrete all over our house the technician from Leak Detection Company find exactly where the problem was and we where available to repair it a much better price, no doubt about it they know what they where doing  very trustworthy company.

Mike and his guys did several jobs at my house over the last year including a partial repipe, new drains, and some work on gas lines. In each case there was great communication from start to finish, a very fair price, and the work was all top notch. So much so that other contractors that have been to my house commented on how good the work looked.

Best of all Mike and team are good people who you'll want to do business with....Highly recommend!

Great job done quickly and professionally.  Pricing was good!  Had dishwasher and disposal replaced. Rich took the time to explain how the new ones worked.  Very happy and will definitely use again!!

George is wonderful, careful, precise and does things right.

We had a leak in a pipe joint behind the drywall in our bathroom.  One of the best contractors in the area said we should call George to fix it.  We did and could not be happier.

Since then we have used George for all our plumbing  problems.  
He returns calls to his cell phone within an hour or two (650-303-6965).
He makes time to fix urgent problems.
He works carefully and fixes the problems.

When you need a plumber, call George.

When I called, they answered the phone!  It wasn't an emergency, so we set up an appointment, which was kept.  Bart showed up on time and the problem was worse than I thought.  Bart stuck with it and fixed it all.  So very grateful.  Prompt, reliable service.

Incredibly fast and responsive service, great prices, and quality work! Edwin came out quickly and on time to give us a quote for our leaking shower drain. He explained the repairs needed and price in a thorough and easily understandable way. He did the work quickly and efficiently and was incredibly respectful of the fact that my fiancé works from home and needs as much quiet as possible to do his job. I would highly recommend this company to anyone!!!

Steve is someone I've relied upon for many years. He's always willing to work and he's honest!

Needed main drain fat-ball clog cleared. Happens every 3-4 years in my 40yo home with poor plumbing design. On time replied to my request thru very helpful Yelp platform. Next day appointment was met on time, masks, booties, tarps on the floor & rootered my drain clog in half an hour. Excellent communication w dispatch, prompt response from plumbers & good work. Didn't get their names but thank you, sirs.

We needed to have our tankless water heater flushed for maintenance.  I used yelp to get quotes from several businesses.  Commando plumbing gave us the best price and I contacted using Yelp. The owner replied very quickly and I was able to get an appointment next day.  Caesar came on time and wore booties to enter our house. I requested him to show me how to do it since I am considering doing it myself next time.  He took time to explain and showed me as he worked. He was kind and knowledgeable and it took about one hour to finish.  Thank you!
We would hire them again.

Started at 8:30 and were out by 3:30 with new copper pipes under my house plus a new main to the street. Professional and courteous. Welcomed my occasional watching. Not messy and cleaned up well. Sheet rocker on time and considerate and a good job. And under my budget. They insulated the pipes, and now my water comes in fast and hot. Nice folks. I can't believe I put this off so long. Call them. Awesome.

Adrian has magical touch with the water heaters! Our water heater broke with no signs and I called Adrian the next morning. Thank god he was able to fit me into his busy schedule on the same day  and helped us to get the necessary part that need to be replaced! He was able to fix everything within an hour and followed up with me the next day! Very dependable and responsible! Thank you, Adrian!

The current more than 10 years old water tank got water leak to floor. Looking for quick service in the market, Alex is one response and offer same day service with tank purchased from home Depot. Arrived on time and detail description to whole process and out-of-order parts replacement suggestion. He performs the state of the art skill and also fixed the previous incorrect installation. Within 3 hours, the new water tank was replaced and back to working status. Highly recommend to use the service.

Contacted the owner Billy and he came out as soon as possible to fix our clogged drain and reattach our garbage disposal.
He was out of town on a weekend when I called with another emergency and although he couldn't come, he texted me with helpful suggestions on how to fix the problem.

Kevin is great and efficient! Today was the second time I needed his services and he did a great job. I highly suggest him for your plumbing needs!

My water heater started leaking over the weekend. Ivan and his crew got to my house in less than an hour after I called him on Saturday. Work was done quickly and very professionally. I would definitely use Ivan again and recommend to family and friends.
