Recommended Customer Reviews

im not one to give 5 stars, because I honestly feel 5 star should be given to a business that not only meets the customer's expectation, but goes above and beyond.
I recently bought a new washer and dryer from Pacific Sales. When the delivery guys came (that's another review that I will be posting) First thing he said was He's not able to do the installation, because my the water valves are frozen, too old, another excuse after another, after another..
In conclusion, I had to send my brand new washer and dryer back, due to the horrific service by the delivery guys, along with all of their excuses.
So i call Courtesy Plumber, because of the many positive reviews I saw. I usually dont depend too heavily on the good reviews, but rather focus on bad ones. My thought is, the bad ones are more correct or more of a consistent representation of the experience i might get. Beside, anyone (including the business itself) can write bunch of good reviews for their business. But of course, they're not crazy to write a bad review on themselves.
So I called Courtesy Plumber. Tom came within the promised timeframe. I explained what happened, and he looked at our washer's cold and hot water valves, and said they're a bit old, but nothing is wrong with them. He then tested out the valves, the water (confirming, no leakage) and said they're in perfect working condition and there's no reason it needs to be changed or replaced. Then said if i wanted to change them, he quoted me a price which i felt it was more than reasonable, but he said, they're in perfect working condition, and if it leaks, he showed me how to fix the problem and actually adjusted for me too.
I was pleased to come across a person/business that still believe in honest business, and not lying to get a simple job done for quick cash, when it' was not needed. I gave him a tip which he refused, but I told him, just for his work ethics and showing me how to adjust, (should any problem arises) was good enough for me to offer him a tip and a cold bottle of water on this hot day. He Thanked me and said if i do decide to do the replacement, to ask for him, and he'll deduct the tip i gave him from my cost.
It was nice to know that there are still business' out there that really knows the meaning of honest business.
You can be sure, I'll call on these guys in the future should i need any plumbing work done.

I discovered the hissing sound of a leaky copper pipe under my Dad's house. I shut off the main line and called another highly rated plumber on Yelp after Courtesy couldn't make the same day (kept my appointment with Courtesy just in case.) Two guys showed. The skinnier guy tried, but could not make it though some existing pipe and house support piles to get to the leaky pipe. They told me they would have to cut some existing pipe to make room for skinny guy, fix the leak, then re-pipe what had to be cut. No thanks... so Courtesy arrived the next day on schedule.
Rick from Courtesy arrived and after a few minutes knew he was not going to fit through the crawl space. No problem. He called back to headquarters and a little while later Jason arrived. Jason struggled, but managed to squeeze through to get to the leak. His final cost was about the same as the other company's estimate. I was happy because Jason did the job in about 30 minutes and didn't have to cut any existing pipe.
This was not my first time using Courtesy Plumbers. I am going to go to them first if another problem arises. As another person had commented, its nice dealing with plumbers that speak correct English and who clearly explain what the problem is and how to fix it.

This occured 08/09/13 at 6:30pm.
I had a leaky shower head issue along with a malfunctioning toilet.
I was going to hold off until Monday but the situation was degrading fast. I was quite hesistant to call on a plumbing service that operated at night because they may try to charge more, but this was an emergency.
The plumber that came was MAURICE. He was quite nice and was straightforward in diagnosing what was wrong. He even went so far as to tell me that there would even be no assurance that he could help me due to the severity of the age of my pipes.
Regardless he tried his best and managed to fix my problem and at the same time educate me on what may happen down the line.
The wait time was far longer than I thought since they didn't get to me until 8:30pm. But the end result was no more leaky shower head.

I had a clogged shower drain and called Courtesy Plumbers after searching on yelp for plumbers in San Dimas. I called about 8:30 and they said they could send someone out between 9 and 11. They told me upfront that a shower drain clear was $110.
Dustin showed up about 9:15 and was very friendly. He took a look at the shower and then went out to get the snake and had the shower drain cleared in about 20 minutes. He brought towels to put down and cleaned up after himself. He was out the door by 9:45.
It was a small job but they were prompt and easy to work with. I'll definitely call them again.

Awesome! Before even hiring Courtesy Plumbers, I was ready to give them five stars. Why? Sean, one of the owners, gave me advice on how to solve my problem temporarily before they could come out. (It was a toilet issue.) This was on a Sunday evening to boot! I could have easily taken his sound advice, and hired someone else -- my point is, he gave me the guidance freely. Next day CP showed up, installed the new toilet, with friendly, fast service.

3.5 stars. Did the job we asked for and provided estimates for future jobs that we might need done around the house. Overall efficient.

I made appointment to come out today, and sure enough a guy named Aaron came on time, did his thing and fix the clogged bathtub drain. Aaron was kinda young but was pretty cool guy. Last week I had bad experience with this flakey plumbing company, even though Courtesy Plumbers was charging little bit more than previous company, but you know what I rather pay little more to a company that is more responsible. That being said, thanx Aaron and Courtesy Plumbers!

Had Dustin out to fix some plumbing, he did an excellent job, went above and beyond. Very informative and helpful. Highly recommend this company.

I need a plumber and I needed one fast! Thanks to Courtesy Plumbers, they were able to schedule an inspection for a condo I was selling and Rick was awesome in quickly resolving my low water pressure issues and answering any other questions I had around the condo including water heater. Definitely, will use them again!

Had a clog in my garage sink which was backing up to my kitchen sink. I called three different places at 7am on a saturday morning. Courtesy was the first to call back at 9am. They told be a guy would be come between 11-2pm. Dustin came right at 11! What a great surprise. Anytime I'm given in a range, I always expect the worse.
Dustin was courteous, friendly, and professional. He was thorough but quick. He made a ""mess"" while he worked but cleaned it up and left it better than he found it!
Would definitely recommend them!
