I reached out to Courtesy Plumbing via the text option on their website about a toilet wax ring leak. They responded in under five minutes with a quote and offered same‑day service, but I scheduled for the following day. Jonny came out on time for the scheduled time period, removed the toilet, inspected the issue carefully, and installed new wax rings. He cleaned the area before and after the repair, and his workmanship was excellent. Very professional experience. read more

This company is highly recommended. We called last night to request service for our clogged toilet. We were given a time frame of 8-10am for the following day. Technician Jonny came as promised at around 9:30am. Jonny was awesome! He did such a great job! Very nice and polite guy. He fixed our clogged toilet in less than an hour. read more

I contacted Courtesy Plumbing for the first time based on their online reviews and ratings, and I'm happy to say they truly lived up to them. My first impressions are: Timely, Courteous, Efficient, and Professional -- and as someone who is retired from the trades, I can confidently say these descriptions are well deserved. My initial phone call was very pleasant, and I was able to secure a same-day consultation and proposal to evaluate my water pressure valve. Richard arrived exactly when they said he would. He was a pleasure to speak with -- very honest and straightforward. The price quoted was fair, so I gave the authorization to move forward. I was contacted the next morning and was pleased to see that Richard returned to do the work himself. This eliminated any concerns about getting a different installer or a "bait and switch." Richard completed the job efficiently, provided a clean and professional install, and used high-quality parts. This was my first experience with Courtesy Plumbing, but they'll absolutely be my first call for any future plumbing projects. Highly recommend! read more

Cory not only knows plumbing, but he found the time today to help me with my car, of all things. I am so appreciative for his kindness, and concern that he stopped his plumbing truck, on a scorcher day and wanted to help me with my broken latch, and open my hood, which he did in under 5-minutes!! What an amazing and thoughtful deed that if I ever have to call a plumber, guess who I'm calling? You're my hero today, and Thank You again! read more

WOW!! John showed up on time and with a smile. He introduced himself, asked me to show him the problem and got to work. Cleared the clogged kitchen drain in less than 10 minutes. As the name implies, he was quite courteous! I highly recommend Courtesy Plumbing! They don't try to gouge you and advise that work needs to be done when it does not. Value, definitely! Honesty, without a doubt! Make Courtesy Plumbing your first call! Thank you John!! read more

Always top notch professional service. They are our go-to plumbers. While we never want to call a plumber, when we have to, we always call Courtesy Plumbers! read more

We had a last minute drain clog, of course on Christmas. Richard came out and fixed the drain problem immediately. Very professional and within the time frame they gave us. Highly recommend them!!!!! read more

You should ask for Jack! Jack came out this morning to fix a broken garbage disposal. He was quick and efficient, he had the problem repaired in just a few minutes. Also very knowledgeable about other plumbing concerns we had. This is at least the 5th time I've used Courtesy Plumbing over the years, and they did not disappoint. They always provide great service at a very reasonable price. Thanks!! read more

I would definitely recommend Courtesy Plumbing! Richard was very courteous and thoroughly explained the process to me. Linda read more

I called Courtesy Plumbers in Covina today for a clogged drain. Adam arrived in 15 minutes and quickly took care of the problem. He was very courteous and did quality work. The price I was quoted over the phone is what I paid. read more

Very slow on creating estimate for my job!! They must not need the work. I am not impressed. Disappointed, that the company doesn't care enough to get estimate out. I understand they are busy but, "COME ON!!" No way to run a business. read more

This company is top notch. I called to share my concerns about a quote I was given from another plumbing company that we had contracted to come and help us after hours. They had seemed reasonable, but then said we needed about $4K dollars of work done to rectify a clogged toilet. I called Courtesy Plumbing and talked to the owner, he is so knowledgeable and after hearing my story he said: I will send someone right now, I'm pretty sure we can fix the problem without all of the recommendations you have been given by the other company. Sure enough, a friendly guy showed up to our door and within 5 minutes had rectified the problem. You just know when you talk to someone if they are knowledgeable-- and these guys are. Very trustworthy. Highly recommend them! Worth every penny! read more

We've been loyal courtesy plumbing customers for the reliability, quick response and quality work, but their customer service and professionalism is truly amazing. Just got a visit from Richard for a minor issue and he was the kindest, most professional plumber and worker of any kind i have met! We'll continue to call in CP for our plumbing needs! read more

Richard was amazing. He took the time to fix my leaking shower and swapped out my garbage disposal that stopped working. He was communicative, showed up on time, and left my place exactly how it was when he showed up. Definitely will be calling Courtesy Plumbing for all of my plumbing needs in the future! Thank you, Richard!! read more

I have now called Courtesy Plumbing 2 more times since my first appointment back in 2020, and have had a great experience with each tech and appointment. They, from the front office to the techs, have always been very courteous and also have very quick response times! I called on a Monday to request an appointment, and they had one for the very next day! Due to my schedule, I was able to request an appointment for Saturday, as they work Monday through Saturday, which is very convenient! I was provided a 3-hr window, and the tech arrived within the estimated window provided. Richard called me about 20 minutes prior to his arrival, which I usually request to ensure all is prepared for the tech's arrival, and he got quickly to work. He asked me what the issue was and as I was explaining it to him, he looked into it. As always, I asked a lot of questions, so am always thankful for the tech's patience in responding and explaining everything. I knew that the flapper my toilet was not available at The Home Depot or local hardware stores, but it was good to learn how to order them online, or through Courtesy Plumbing, as it would be good to have on-hand if we continue to run into issues and need to call for another appointment. The online website no longer offers any coupons for existing customers, but there is one for new customers. As always, great customer service, courteous, reasonably priced, and very professional! We love supporting local businesses and this company has been in business since 1970. Support local businesses! Read less read more

I give them a five stars out of five, came when they said they would, their technician (Shaun) knew what was wrong and what to do, for the price I was quoted. This was the second company who came out to fix the problem.... the first company who came out yesterday couldn't fix the problem, tried to sell me a $1600 hydro-jet, (when I knew the line just had to be snaked), charged me a $55 service charge after doing nothing, and left. Courtesy did what they said they were going to do. fixed the issue, at the price they quoted. They will be my new plumbers. read more

I had my house re-piped and re-drained by Courtesy Plumbing. I originally wanted to fix multiple fixture issues around the house. My home was built in 1957 with original galvanized pipes and cast iron drains. Cory advised me that attempting repairs on multiple fixtures might open up a can of worms and suggested that it's time for a re-pipe to PEX instead of wasting money trying to replace fixtures tied into old plumbing that's near the end of its life. He sent out Express Air to test the demolition areas for asbestos. When the results were negative, the job was scheduled. Ed and a team of 3 other guys were sent and got started at 8 AM. Running both the new water line from the meter to the house and the re-pipe was completed the same day. I had water again by 3 PM. When Ed was in the crawlspace, he said the cast iron drainage doesn't look like they have much life left, and advised me to change it out with ABS while the walls were already opened up. He showed me the main cleanout that ran down the middle of the entire house. It had a partial clog. I asked why not clear it? He said I run the risk of cracking the cast iron. I was convinced and agreed. Ed and his team came back out a second day and the re-drain was completed by that afternoon. I got new fixtures for my bathtub and shower. All the u-traps under sinks got replaced. I got a new pop-up for one of my sinks at no extra cost. They dug down multiple feet to install an ABS pipe with a cleanout at a section of the main sewer line. I didn't have a cleanout there before and now I got one. I'm fortunate to have a crawlspace where everything was accessible with minimal demolition. The house was designed where all the fixtures were easily accessible without demolishing bathtub and shower tiles. At the end of the job, they patched the demolition areas, and I only had to handle the repaint. It was a job well done. read more

Contacted them via Yelp when I noticed a small slow leak. They responded very quickly and I was able to make an appointment for 2 days later. Their rep Richard showed up timely, during the early part of the appointment window which I very much appreciated. He figured out the issue and explained what it was in detail. He provided a quote in case I wanted them to do the repair, but with his explanation I was able to fix it on my own. Very quick and professional and not trying to nickel and dime me unnecessarily. I will definitely contact them in the future if I have any other plumbing issues. read more

Richard and Andrew from Courtesy Plumbing came out to replace our old tankless water heater with a new one. During our estimate, Richard beat the price of a bid from a local competitor (thus earning our business). Richard and Andrew made the installation quick and painless. They were friendly, knowledgeable, and kindly explained what various parts of the new system do and how to change the settings on our new system. We have used Courtesy in the past for all of our plumbing needs and they never fail to provide sage advice, fair (and realistic) estimates, and speedy service. read more

Had an outside faucet that was worn out and a bad fitting that was spraying water everywhere. We decided to use Courtesy Plumbing. See below for why. Jack is an experienced, knowledgeable and highly efficient plumber. Courtesy Plumbing prices are reasonable/honest and the owner, Jeff, is prompt and easy to work with. If you look at the posted pictures of their work, especially the sweated joins, it's clear this is a firm that does only top quality work. Yelp automatically gives out 5 bids for a project. No one beat Courtesy Plumbing price, had equal quality work or wanted to show up as quickly. Additionally, several wanted to charge us just for estimates. Needless to say, this is the only plumbing firm I intend to use for our future plumbing needs. Thank you, Jeff and Jack for your honesty and professionalism. read more

He made sure I was ok with the repair by demonstrating that the leaks were taken care of. Thanks Richard! I would highly recommend them for all your plumbing needs! read more
