They gave me a quote of 900$ for one leaking tap !! That is preposterous and I hope they realize they are losing business by giving dishonest quotes like this. read more

The team help us cleaning and change the main pipeline, installing the 2-way clean out and installing get city approval. They are professionals with good experience and altitude. It's good experience working with them. Satisfied with the service they provided:) read more

Very impressed with the service. Francesco is a knowledgeable plumber and figured out the issue with my dishwasher quickly. He was patient and talked me through what could be the cause for the blockage. Highly recommend the prompt service. Thank you! read more

Edgar and his team are amazing. They are prompt and communicate quickly. He has helped us twice in the last 4 weeks at 2 separate locations. First was a sewer blockage that they cleared quickly and second was an old, rusted, dirt filled exterior storm drain. They successfully cleared it and also found three small golf balls from inside the pipe. He is very knowledgeable and offered solid alternatives for us to consider. Once he and his team solved the problem, he provided additional steps to ensure the problem never happens again. Edgar was prompt in providing us with an estimate as well as getting to our home quickly in the midst of some devastating storms. Thank you, Knockout Plumbing for all your help and assistance during a very busy and rainy time. We highly recommend them! read more

Great service. Honest, fast and reliable. Came working an hour at 830pm. Really appreciate how fast they were and the tech was honest about the work and actually helped me find the cheapest option for the repair. read more

I had a clogged up kitchen sink and they were able to fix it in less than 20mins. The technicians were very knowledgeable and nice. The price was very reasonable and lowest I could find. Highly recommended! read more

We had such a great experience with Knockout Plumbing. We had a sewage backflow due to roots in an old sewage pipe on Christmas day, and Knockout Plumbing was the first to get back to us early on 26th morning. They were here to do assessment and start repairs by noon and got our problem fixed in a day with better price than what we saw across other companies. Edgar is super communicative and a great person to be dealing with; The team is professional and was very easy to work with. I'd highly recommend the company overall. We're definitely sticking with them through any plumbing issues in the future. read more

I recently had my entire home copper re-piped by Edgar and his company. From the start, I was impressed with their work proposal which clearly itemized and outlined every task to be performed, including sheetrock repair and cleanup. Their work and customer service were also impressive. They were timely, accessible, attentive to detail and their prices were comparable to other estimates I received. They also offer a very generous warranty. A minor problem came up after the job, giving me an opportunity to try out their warranty. Jorge, their head plumber, returned a couple of times and corrected it to my satisfaction. I later got feedback from another plumber who said that Jorge's work is impeccable. Apparently, the adjoining seams of copper pipes need careful cleanup to prevent corrosion later. This is sometimes left undone. In my case, Jorge took the time to clean it up, even though I would not have known the difference. I am more than satisfied with their work. I'm glad that I picked them for this major project. read more

Very responsive and did a simple repair quickly and reasonably priced. I will use them again next time.

I had two rusted sinks in a bathroom that needed replacement. Problem was that an equivalent sink was not available in the market. Edward was very innovative and helpful. He suggested replacing the shelf and piping that goes with the sink. In a matter of less than 2 days Knockout Plumbing crew gave me a new bathroom shelf, along with 2 new sinks in a full working order, but much nicer looking than before. I definitely recommend them and will use their services again. read more

The folks at Knockout plumbing did an excellent job repiping my home, and it really showed that they care about their customers. They provided super competitive pricing, which included services that other companies didn't offer: they do drywall and texturing, so I only had to take care of the paint after, and they also pulled the permit and took care of the inspection. During the initial estimate, Edgar did a great job of explaining the process of the repiping, the materials they used, and the care that went into their work, and especially what they would do to ensure that the floors were not damaged in the process. They scheduled around the city inspection, and the work was done quickly and on time. They were prompt to address any issues that came up as part of their work, and once the work was completed, I found no damage to the floors or anything similar. They really made the process painless and easy, which is quite a big feat for such a big job. A couple of weeks later, I ran into another issue that was unrelated to the work they had performed and I called them up again, Edgar went above and beyond in providing me a very competitive price for that other problem, to make sure I was satisfied with their overall service. Every interaction I had with Knockout was positive, and they really showed that they have excellent customer care. I'm really happy I used their services, and I'll be sure to call them should anything come up in the future. read more

Two of our tubs were clogged and drainage cleaners didn't help. Edgar came at short notice after a same day appointment on a Sunday evening and helped us out. On time, polite and professional. Figured out the issue and explained to us, and gave upfront estimate for snaking. Reasonable pricing. Highly recommend. read more

They came the next day, gave a reasonable estimate, came back later, fixed the problem beautifully! Easy breezy. Pleasure doing business with them! read more

Had a backed up bathtub that needed some attention. I was in contact with a rep in less than 30 mins. Scheduling the service was really easy and clear. I received text updates regarding each aspect of the job. Axel and Edgar were knowledgable and could clearly articulate each aspect of the issue as well as details about how to fix the issue. I never felt rushed or pressured nor did they ever push for an 'upsell'. All repairs were clearly explained along with, what I felt was a fair price for the work being done. I couldn't recommend them enough for your plumbing needs. read more

Knockout plumbing did an amazing job on our rental property. They are professional, have great communication and are a pleasure to work with. I would definitely recommend. read more

The sewer line in my apartment building was clogged in Saturday night of a holiday weekend. I called a couple of big plumbing company like Rooter Hero - no one called back. I contacted Edgar from. He immediately came and cleaned sewer pipe. He was professional and honest. His price is very responsible compared with the price of big plumbing companies. I very recommend. read more

Hi, They repaired my plumbing in front yard and their work was great. They were responsive and showed up in timely manner. read more

Edgar and the team did an excellent job on remodeling the shower and bathtub area for my home. The team is super professional, reliable, and efficient. They come well-prepared and carefully protected my floor and the surroundings. Also, they cleaned up everything and took away all the disposals after their work. Edgar is a very nice person. He is responsive and flexible in the whole process and in all of our communications. When the project is close the end, he kindly offered to help fix the surrounding walls and paint that was scratched before with no additional cost. I would highly recommend Edgar and his team to anyone who needs a bathroom remodel or a plumbing project! read more

My bypass valve on my (disconnected for servicing) water softener suddenly started leaking in my garage at 7PM. Unfortunately, the only way to stop the leak was to turn off the water to the house for the whole night. After sending out a Yelp request the next morning, there were several responses but Marlene from Knockout was quick to offer technician availability that day. Even though Jorge was already on a job, he was able to finish and get to my house in an hour! He assessed the issue and explained that the valve is now out of code. Putting in new piping to meet code was more expensive but there was the added feature of not having to turn off the water to the entire house! The estimate was expensive but Jorge and his manager worked with me to lower the cost a bit (I am a senior). Jorge quickly got the necessary part and spent a couple hours (in the very hot weather) to finish a great re-pipe and valve job. I had running water again! Jorge did good work, was friendly and polite during the whole job. Footnote: it turned out that the old valve is needed for the old water conditioner. I called Knockout the next day and Marlene was actually willing to drive to my house to drop off the old valve! I really appreciate the friendly and courteous service at Knockout (it really matters these days!) and will definitely consider them again for my plumbing needs. read more

Extremely impressive customer service. We had a clogged drain, and a technician came to fix it. It then appeared to be fine. However, the clog returned that evening after showers were taken. Edgar, who owns the company, came out himself later that same evening. He cleared the clog again, and found that some old cast-iron pipes were part of the problem. He sent four workers out on a Saturday to replace the old pipes. All of the work was done in a very timely manner, which was much appreciated. I highly recommend Knockout Plumbing and Repipe. read more

Jorge was very professional. He gave an estimate for my garbage disposal as well as water shut off knobs. I will definitely call them again. Thanks so much. Martha M read more

What a wonderful service, changing the main water line, very professional polite, and knowledgeable.

I have a 60 year old 4-plex rental building in San Jose. The water pipes are original galvanized iron pipes and they started affecting water quality for my tenants in the last 12 month or so. After getting estimates from 3 licensed plumbing companies, I hired Knockout Plumbing and Repipe to do the project. All 3 companies have extensive experience in repiping project. They all have good customer reviews on both Google and Yelp. Knockout gave me some discount. They started the job on May7th and finished the job on May 11th. Only in the first two days, they needed to shut off water for about 10 hours during the day. They use top quality parts. Their young plumbers are well-trained and professional. After the entire plumbing system was replaced, they did extensive test to make sure no water pipe leaks. They took care of San Jose City inspection well. The two inspections were scheduled timely and went through smoothly. The owner, Edgar, is professional and easy to work with. His younger brother Juan and his staff member Kevin also left me with very good impression. I highly recommend this company to anyone who has similar needs. read more

Jorge, Frenado, Tirso, Eduardo and Francisco they are professional and get the problem solved quickly! Really recommends to have them for solving your plumbing related issues! read more

Edgar team did a fantastic job replacing sewage pipe under the house. The team was professional and punctual and completed the job in few hours. The way they covered the area/floor with sheets and then cleaned up everything post job completion was very impressive. The quote that they gave us and the final pricing was less than the other quotes I had. Would highly recommend Edgar and team for your next plumbing project read more

Knockout Plumbing did prompt service to snake the maindrain of my apartment. I send out request on yelp, they give quite reply, arrived in around 1.5 hours and resolve the problem. read more

Called for sink drain blockage. Fast and good work in san jose area..got appointment fast

Our kitchen sink had been leaking for weeks and had a clog somewhere along drain pipe. Had it serviced twice by sketchy plumbing company just around our area and was unsuccessful in fixing the problem. Had a difficult time reaching back to the same plumbing company to see if there's anything else they can do to fix the clog but they have been unreachable and had a feeling they've totally given up on us. Came across Knockout Plumbing while looking up online for a better plumbing company. Was able to make a last minute appointment with them the following day. Francisco showed up and fixed the leak and clog in our kitchen sink so professionally. Very knowledgeable in what he does and would really explain to you the bits of little details there is to know about the problem. The service fee is very reasonable as well and they will not try to scam and steal money from you just like what other plumbing companies out there do. Highly recommended! One of the best plumbing service companies in the bay!!!! Thanks Knockout! read more

Had a problem with slow drains and leaking drain pipes. Edgar provided a reasonable and competive quote to fix the problems. He is responsive, professional, courteous and willing to explain details about the jobs. All work was professionally done within the time frames given by Edgar. They are careful while working inside the house and clean up any mess they make. Work is quality and meets city codes. I hope to not need a plumber for a while but when I do I will call KnockOut Plumbing. read more

Mr Ramirez delivered me a good job after he replaced my broken water heater with a new one!

Used Knockout Plumbing to put in a clean out. The work was done quickly and professionally. Communication was easy. The process was explained well. Would certainly use them again. read more

Edgar is highly knowledgeable. He is the guy you call when other plumbers fail. While this is a new business, I've worked with Edgar for years through his previous employer and have followed him as he starts Knockout. For example, we recently had a pipe leak, and the initial plumber sent out could not figure out the issue. So I got ahold of Edgar, and he rapidly figured out where the problem was and got the pipe replaced asap. I've learned my lesson, call Knockout first and don't waste time with others. read more

I had an issue related to my kitchen sink and wasn't quite sure what the issue was or where the issue was coming from, there was some kind of slow water leak that evidently had been going on for quite some time. I took a look at the plumbing alternatives and found "Knockout Plumbing & Repipe" and read a few reviews. I thought to myself this place seems good so I placed the call. First of all the person scheduling the appointment was very professional and set up Francisco to come out. Francisco came out not only same day but within a few hours. There are other positive reviews of Francisco on Yelp and they are all accurate. Francisco was very professional, personable, knowledgeable and everything you'd want from someone entering your home for the first time. He identified the problem within a few minutes, we came up with a plan and took care in putting things back in place after he was done. Bravo Francisco....I hope I don't have any similar problems in the future but if I do I'll call and request Francisco to "Knockout" the issue. read more

We had a water leak under the house not knowing what is leaking, we had Knockout Plumbing come to give us an estimate. They arrived on time, crawled under the house, took pictures and explained everything that was going on under the house. The prices were very reasonable. they returned 2 days later with a fantastic crew. they covered everything to keep it clean. While fixing the problem they noticed another problem with our 50 yr old pipes. Again took pictures explained what was going on and set up an appointment to complete that project. They did an amazing job. Cleaned up everything and send over Juan to complete the mud/drywall. I would recommend this team anyone who wants the job done well and on time as the quote. read more

We had toilet and bathroom clogged over the weekend. I called Knockout Plumbing for the help, left a voicemail. Got a text immediately and got a call within 10 minutes. I talked to Edgar and explained what's the problem. He and his crew came within a couple of hours and did the snake for the sewage pipe. He told me at that time that this pipe is very very old and we would have to replace it and the problem would happen again. And as he mentioned the next day we had the same problem. He came back again next day did the snake again, put the video camera inside the pipe, showed me exactly where the problem was, where the pipe was completely broken, tree roots were gone in the sewage pipe and bathroom tissues and other stuff were getting clogged in those roots. We scheduled the date to replace the whole sewage pipe. Edgar did all the work with whatever needs to be done with the city. He and his crew came on time as per schedule and replaced the whole pipe without any damage to the house. I'm very satisfied with his work, his honesty and his expertise. He and his crew are very professional and know what they're doing. They did all the work and got everything to city code. Until the pipe was fixed Edgar called twice a day to make sure everything is working and I was comfortable. One day after his work he came to inspect everything to make sure everything is cleaned and working. He gave me 40 years written warranty on his work. Amazing guy and crew, would highly recommend to work with him and his company. read more
