This was my week of plumbing repairs. first i needed a new AC/Heater & compressor installed & Wayne Cornett came out gave me an estimate & the job was done immediately. the workers were friendly, professional & cleaned up everything. the next day my Hot Water Heater broke & that needed replacing. i called Wayne over the weekend and on Monday morning they came with the new HWH & it was installed. once again, 5* service. I have used Cornett Plumbing since their dad had the business. Always a great experience & priced fairly. i never worry that they are taking advantage of me. read more

I called Cornett for garbage disposal and bathroom faucet replacement. My first impression was Minell, who returned my call and was awesome. She was friendly, informative and answered my questions. Josh and Ray came to do installation. They too were friendly, answered my questions, worked quickly and cleaned up very well. I will definitely recommend them and Cornett plumbing. Karen read more

We have used Cornett plumbing and heating for over 23 years, and have always found their service to be 5 star. They are professional, polite, leave the work area very clean, and are very prompt. read more

Super responsive! They scheduled us for drain clearing the next day with a window of 10am-1pm. They arrived at 10:05am, assessed the issue and cleared the problem quickly and efficiently. In and out in under 30 minutes. They were very professional and polite. read more

Wayne installed our heater 5 years ago and we have used him for regular maintenance ever since! He's professional, helpful and knowledgeable. He was willing to even call 30 min prior to coming so I would be able to leave work to make sure I was there to meet him. The installation and maintenance prices are very reasonable and affordable. We will continue to call Wayne! read more

Josh and Tim from Cornett Plumbing are excellent plumbers. They under the issues/problems well and do the work thoroughly and clean up when they're done. Excellent value for excellent quality of work. I've used Cornett Plumbing several times now and I'm always satisfied. I highly recommend this company. read more

So pleased with the service from Cornett Plumbing! Mark and Ivan came out on time as scheduled. Mark listened and responded to my questions. He provided a reasonable estimate. He communicated with me throughout the repair. Excellent customer service and timely repair! I am so relieved the leak was fixed and clean out installed. Have already recommended Cornett Plumbing to 2 people. read more

Called Cornett Plumbing to fix my garbage disposal and was able to get someone to come out same day. Dave O tried repairing the garbage disposal but recommended replacing it due to its wear and tear (including some corrosion and leaking at the base). He was able to fix it within 2 hours and also fixed the water pressure in my kitchen sink. Pricing was fair for the service. Highly recommend Cornett Plumbing! read more

I know that I need a new mini-split in my garage, but I can't afford it right now. I called a couple of other companies before Cornett, and they just tried to sell me on a new system (upwards of $6700 for a single zone MINI SPLIT) and would not just recharge my system. I know I have a leak, but I also know that if I re-charge this system it will work again, for as long as it works again and right now, that's realistically all I can afford to do. I called Cornett, and explained and Wayne agreed that he can do what I asked. He came on time, and did just as I asked. He didn't try to sell me on more, but when I asked he did give me a very reasonable quote for a new system whenever I am ready. So now I am able to work in my garage office again during the summer! Since they do plumbing I also got a great quote for a new water heater when I am ready. I have worked as a construction project manager, so I have experience with all kinds of contractors and I was so happy to have a great experience with Cornett. They are knowledgeable, and fair and I 100% recommend and will call again. I just wish he'd given me a magnet or something for my fridge so I'd have their number on hand ha ha. read more

I can't say enough good things about this company. In the ten years we've been using their services they have consistently offered great service at reasonable prices. They are quite responsive when called and schedule their visits quickly. We've had them install clean outs as well as deal with smaller issues and the plumbers they send are always courteous and helpful. read more

Amazing and prompt service! Always friendly and honest. They always quote a great quote, and I've compared and they are always the lowest. I love that they aren't trying to sell you on things you don't need. When we call they answer and come right away to complete the service. I highly recommend this place. read more

I've been with Cornett Plumbing for the last few years. I absolutely love them! They are reasonably priced and take care of their customers. I strongly recommend them to anyone who needs a great plumber. read more

Cooking for 30 people and all of a sudden, kitchen sink (both sides) backed up. It's a religious holiday and I needed my sink to be working. called about late morning and had service tech Mark at house by1:30. Cleared the problem and now I'm back to using the sink. Thank you Cornett Plumbing for understanding my situation and taking care so quickly. read more

Every time I've called Cornett they were able to quickly resolve my problems. My furnace needed a new inducer blower and it was cold, so I needed something right away. Wayne came by the same day and was able to get me a quote, but when I pressed about needing it sooner he was able to get the part sooner and have it installed the next day. I've also used Cornett before for plumbing things, and they may not be the cheapest in town but they work quickly and are very helpful at referring you if they don't have the exact service. In my case I had a sewer main that needed to be cleaned out from the roof and they referred me to someone who was so good, he was also able to fix a bathtub that I thought was unfixable. Thanks so much! read more

Thank You Cornett for your quick response in servicing our clogged kitchen drain line. Your Journeyman Plummer Mike was wonderful in troubleshooting the issue straight away and cleaning the kitchen drain line quickly thru the exterior 2" cleanout. Very professional! We have used Cornett Plumbing and heating services for almost 30 years now and always very pleased with the end results! And yes, reasonable pricing! read more

Unplug shower drain. Cornett showed up on time. Unplugged my shower drain and cleaned up the mess in the shower. They only took an hour. The cost was very reasonable. read more

I got referred by my realtor. Everything went well as Yelp stated, others plumbing company quoted $3000.00 and up but Cornett charged very reasonable and professional. I wish I knew them earlier so I won't be fooled by others. Highly recommended!! read more

Dave did a wonderful job replacing a corroded water valve under a sink. Immediately, the company responded to my inquiry and I was able to receive service the next day. Dave was very engaging and polite, at first a man of few words, but diligent and focused on the job at hand. I was able to ask him some questions about a few other concerns and he shared his knowledge with me to help me make an informed decision. Thanks for your help! read more

I had a broken HVAC duct that needed to be repaired. I received the best quote from Cornett against 4 other companies. They truly paid attention to my needs and most importantly took care of the problem. This company is very honest, very professional, and certainly provided us tremendous value for the work they have done. I will continue to use them and certainly refer them to any plumbing/ HVAC needs in the South Bay Area. Thank you Dale & others from Cornett. read more

Today, Dave installed our kitchen & patio faucet so perfect ! Wow he fixed them so fast, this is the 2nd time we called for a break down at home, Dave is so great, loved his work, perfectly, perfect if we could rate him as 10 *********** we would. Thanks so much Dave. Lee H. read more

TERRIBLE SERVICE! Do not use this company. I've called for several days to set up an appointment and on my last attempt to reach someone, I get this rude woman on the phone who says her name is Minel (spelling not sure because she said she doesn't have to spell her name!) who apparently thinks she can be as rude as she wants to be and it's ok. When asked to speak to the manager she says she is the manager. Who ever the owner is of this business please be aware you have the wrong person answering the phone! There are lots of plumbing companies out there so pass up Coronett and find one that treats people well. I DO NOT RECOMMEND THIS COMPANY! To the business owner's reply...THAT IS ABSOLUTELY NOT WHAT THAT CONVERSATION WAS ABOUT! WE DIDN'T EVEN GET TO THE FEE! And if you don't think she was rude, then that explains why she was rude. You let it be ok! read more

Our water heater started leaking during the holiday weekend, but Wayne was quick to respond to my inquiry. We have always used Cornett for our plumbing and heating needs and they didn't fail us this time either. George came today and did a great job installing the new heater. Always happy to support a local small business! Just waiting for my final bill, but they have always been fair with their prices. Thank you, Cornett! read more

When I called Cornett on 7/3/24, the day before the Fourth of July holiday weekend, I fully expected to arrange an appointment for the following week to fix some annoying but non-emergency plumbing problems. Instead I was informed that a technician would arrive between eleven and two that day! As a long time and well satisfied Cornett customer I expected good service but this was above and beyond. Roger arrived at 1115 and diagnosed the problems in a few minutes and informed me that, luckily, he had the cartridge needed to fix one of the problems on his truck. In about an hour and a half, my bathroom was again functioning as it should. If you need plumbing services or any of the associated services listed on their website, give these folks a try. They know what they're doing and they run their business the way a business should be run. It's a pleasure to deal with them. read more

I have delt with this company for years and they have always provided good service. I have never had a problem with them. I had a plumbing problem this week and they were very efficient as usual. read more

We had called Cornett to check our HVAC, which had stopped working. Wayne came out and quickly determined the thermostat had failed, and it was replaced quickly. While on site they checked the remainder of the HVAC and confirmed it was working properly. I am appreciative of Wayne's prompt response and timely resolution of my problem. I plan to contact Cornett for my future plumbing and HVAC needs. read more

Excellent response time and service. Wayne was able to identify the issue with our furnace within minutes and ordered the part and installed next day for us. Thanks, Wayne! read more

Shame on me for not asking more questions, but when I asked them about a loose tile under my toilet that I suspected was the result of a leak, they said they'd have to send a person to see if that was the case and said nothing else about a charge for giving the quote. When the plumber came, he said he couldn't tell anything without lifting the toilet up and breaking the seal. For that it'd be 250, or 700 to just get a new toilet entirely. When I asked him to write down the quote so I could ask my husband who wasn't home at the time, he charged 125 for just showing up to provide the quote. Having gotten quotes for non-urgent plumbing jobs before without being charged for a quote, I was shocked. I understand some plumbers have service call fees, but to not be upfront about it ahead of time means I'll never use them again and stop recommending them to my friends, neighbors, and Nextdoor. read more

Aug 2023: Sold me an AC unit that broke then charged me a fortune to fix it and it didn't even last a 6 months!! When I texted to come back and make it right he blew me off!! Run away...they take advantage of people read more

Roger from Cornett Plumbing was excellent in fixing a noise issue from the hot water circulation pumps in my condo. He followed thru and assisted when the boiler company showed up. This is commitment to excellent customer service. I would recommend him highly without any hesitation. Very knowledgeable and provided excellent customer service. Thank you!!! read more

Our faucet burst in the bathroom sink and water started overflowing the entire bathroom. Mikey from Cornett was the absolute best! He was at our apartment complex helping another unit, and popped over right away to help us. He fixed it immediately and even patched up a hole which was unrelated. We appreciate the service at Cornett and will always be calling them for any plumbing needs! read more

We recently had a central A/C unit installed. Wayne gave us a great estimate! He didn't push replacing our existing central heating unit that other companies were recommending. Further Wayne didn't try to sell us a larger more expensive unit as he felt we didn't need it, this was also in contrast to other companies. Cornett Plumbing and Heating is honest, does great work and is very reliable. I highly recommend them for your A/C needs. read more

Both my sister and I used their services quite a few times. We trusted them although their charges are getting more expensive which we understand things are changed after Pandemic. The recent call was not satisfactory at all, workman went, could not complete the job as it was a community public issue, workman did call me to provide reason for not completing the job, but left without putting back what he removed. I called their main line, emergency hot line with no response, called the workman and he hang up on me at the moment he answered and I said Hi. Believe me, the charges were ridiculous high for an incomplete service. The 3 stars was rated overall satisfaction of all the services in years. read more

Wow! I called on Monday to say i needed a new water heater. Said they'd be out in 2 hours. I said thank you but how about Tuesday morning. They said yes between 9 and 11 AM. On Tuesday morning they called me a little after 8 AM and said they were on their way. As I was leaving the house for a few minutes, I said give me a half hour and I will be right back. When I got home, they were out front waiting for me. They removed the old water heater, took it away and installed the new one in a very reasonable amount of time. The two guys that did the work were very polite and informative and thank you Cornette plumbing. I will definitely call you for the next issue. read more

Once again, Cornett came through for us. Mark diagnosed the main line blockage problem, scoped it, and went to work. Everything was put back to as he found it. A very responsible company that we're used exclusively since 1979. read more

We had an issue with our kitchen sink backing up. Roger was sent out to address the issue. I received a call 20 minutes prior to the 2 hour window they gave me letting me know they were going to be there early (I wasn't available to attend to them before scheduled time). First time out, he asked very few questions and was in an obvious rush to move onto the next job. Visit took no more than 20 minutes (all he did was snake the pipe), and charged me $225. The invoice states that the work included a 30 day warranty. After a few days we noticed that when the water ran for an extended period of time, it would start backing up again. Contacted Cornell to have them send someone out to investigate further since snaking the pipe didn't ultimately solve the issue. Roger was sent out again. He arrived with a terrible attitude, was extremely rude and unprofessional. Would not let me speak or explain what was going on. After a few minutes he explained that he was pissed off because he had been waiting around for me, I tried to explain that the doorbell doesn't ring inside, so I couldn't have heard it and that I had no calls from them in attempt to reach me. He said he did call (later found out they called the old number on the account which I updated the first time I contacted them). At the end of the day, this all could have been handle with SOME professionalism. It was completely uncalled for giving me such a nasty attitude and being so rude. Clearly I wasn't trying to waste his time, it was simply a breakdown in communication. Not even an attempt to have a conversation without storming off and telling me to hire someone else. Unreal. Also, it would be great if he could be taught how to write legibly on invoices to reduce the need to dispute the legitimacy of the "work" he claims he performed. Grow up man. read more

Again, top notch service from the people at Cornett Plumbing & Heating. After water from a pin hole leak in the ceiling damaged one of the rooms in our home, my wife and I decided it's time to repipe. Went with PEX and got quotes from several contractors to see how they compared to Cornett. Some bid higher while others quoted lower. Some of them had only been repiping with PEX for a short time while others had years of experience, but also tried to up-sell equipment not needed as well as overcharge for the job. Jason from Cornett came out for the estimate. Explained the pros and cons of PEX and copper as well as the costs. I brought up the items other plumbers had mentioned during their estimates and he explained they were not needed or would not make a significant difference to water quality and only add to the cost of the repipe. Discussed the route where the new water lines would go and met with the abatement company to show where he wanted the holes to be specifically cut. After the abatement company finished making their cuts, Jason came out with his brother, Josh and the pair worked quickly and efficiently to complete the repipe. The duo worked independently on their assignments to finish sections of the house fast but employed a sense of team work, if that makes sense. At the end of each day, they cleaned up their respective areas nicely and brought any old copper pipe and debris with them. While working the job, I pointed out some non-related plumbing issues I had and Jason took care of those as well for a significantly less cost than what I thought it would be. Nothing but positive comments for these guys and a continued commitment to excellence from Cornett Plumbing & Heating. read more

I had a great experience with installation and removal of my old furnace. Wayne & Miguel were fantastic! The job was Professionally done, cordial and explained everything to me and they made sure everything worked properly! They cleaned up nicely and all at a fair price Highly recommended read more

We recently had flooding in our garage due to a slab leak. We called Cornett and left a message. It was late at night so we honestly didn't expect them to call us right back although the yelp site does say they're 24/7. I called again the next morning and talked to the secretary who told us someone would come take a look that morning. Sure enough, Joshua came within an hour to take a look. They're super busy these days so his earliest availability wasn't until two days later which wasn't ideal but fine with us. He said the job would take a day and a half but he was actually able to finish it all within a day! He did an excellent job and was very friendly and professional. We could tell he has a lot of experience and he knew exactly what he was doing. We were so stressed out about the leak but his confidence put us at ease. He even talked to the HOA office for us and confirmed that it would be fully covered. I highly recommend Cornett for any plumbing needs, especially Joshua! read more

I can't imagine trying to get a warranty call with this company when I can't even get an estimate for a new install. I'll begin with the receptionist, they lack the art of customer service, when I first called, I mentioned I was looking to get a quote for an AC and Heater installation on a property. They seemed reluctant because I wasn't the home own, although I had full authority to get a quote started. The receptionist was unwilling to help out to proceed with a quote for the property till finally, I had the home owner call them and tell them that I was authorized to get a quote. I mean, I understood their hesitancy with it however, I did not understand their lack of effort to help me out to move it along. So finally, the appointment was made for the technician to come out and provide us a quote. The technician was on time, nice and respectful. He took about 10 minutes to look around and mentioned, yup, we do these installs all the time. He mentioned we'll get that quote out to us soon. Well a couple of weeks have gone by and haven't received a quote yet. I called for an update and once again, the receptionist wasn't much help again. A couple more weeks went by and finally, I called again and asked to speak to the owner. When I spoke to the owner, I mentioned before I left a negative review about the service of your company, I hoping that you'll be able to remediate it and give you guys a fair chance. I mentioned I understand how things call fall through the cracks but please note, this is us try to hire you and give you money for a service your company provides but it's getting me very nervous if I would ever need a warranty call on the installation. He mentioned he'll look into it and get back to me. Well the owner of the company, much like the receptionist and the serviceman, did not get back to me after weeks of waiting. I always say that customer service is always a reflection of management and this once again proves it. This also seems to be an ongoing issue with this business. I would strongly recommend that you call another business for a quote at the same time, in case they don't get back to you too. So if customer service isn't a priority, then Cornell might be the company for you. Again, I didn't have the opportunity to hire then and experience their work but they were way below my level of customer service expectations. Update: 05/25/2020 Oh, I don't mind you guys choosing not to work with me, but let me know. Don't leave people hanging for a response. Again, I can't imagine trying to get a warranty. I've already installed a new unit and paid someone else $10k. read more
