By The Book Plumbing Heating Air Conditioning

We had a minor leak affecting our downstairs neighbor under our toilet and things were escalating.These guys were the only ones available for same day emergency service and we were almost shocked they could help us.

From the initial phone call to the owner coming himself to help us, everything was extremely professional and courteous. Prices were also very reasonable. Will definitely need to schedule another service with them when it comes time to replace our water heater.

I had a very disappointing experience with this company. I had a slab leak and called By the Book to get a leak detection done. I made it clear that leak detection was the only service I needed from them that day, as I was going to weigh my options for plumbing. Leon came out and immediately was very condescending right off the bat. I get it, I'm a girl, I look young, but assuming I'm dumb is a bold move. I ask for leak detection, and Leon is already giving me the go around about why he can't do that. He tried telling me I don't have any water damage, even though I felt warm spots underneath our entire kitchen (meaning water was leaking and spreading under the vinyl). If I listened to Leon, we would have severe mold damage under our floors. I also knew there was water flowing in our bathroom and Leon said he didn't hear anything and implied I was just making up the noise. After not doing what I requested and instead doing a walk through of our whole house, Leon said he would be back in 5-10 minutes. He came back a full HOUR later! I had no idea what he was doing as I thought he was maybe preparing his leak detection equipment. Instead, he was ignoring my request and coming up with 10 different plumbing options to repipe the entire house. I was annoyed because all I wanted was a leak detection and Leon was refusing to do that. I quickly told him I wanted him to leave and he got visibly upset and threw a tantrum! I've never seen a professional old man do this. He told me I wasted his time, which I quickly reminded him that I never asked him to sit in his car for an hour. After throwing a fit, Leon finally left and I still had no leak detection done.

I called a different company, Mastercraft, and they came out, detected my leak, and showed me that I had bad water damage under the floors. They were very kind the entire time during the water remediation process and told me how to do everything through my insurance. I then called California Repipe and Plumbing to take a look at the leak and they had a very quick response time. They were extremely patient explaining the entire process to me and gave me very reasonable prices. It was clear they were not trying to take advantage of me and were there solely to help me.

By the Book Plumbing clearly does not train on customer service and they leech off people who are desperate for fixes. Be smart and do NOT hire this company! They will take advantage of you and be condescending the entire time.

Late on a week night, our bathtub handle broke causing water to flow out uncontrollably. Leon came out and gave me a few options, the first being the best option if it were possible. It ended up working and saved me $$$ and him from another trip. Leon was honest, reliable, and got the job done right and in a timely fashion. He showed up at 9:15pm and I was all fixed up by 10:15. Great, honest, guy. Highly recommend.

He came out on a Sunday evening in an emergency. He was very helpful & didn't try & over charge us or scare us into something we didn't need.

Highly recommend By the Book plumbing, the team came out on a Sunday and installed a new water heater. They answered all my questions and concerns which gave me peace of mind. If you're looking for a reputable plumber these are your guys!!

Was able to make a appointment that worked out for me, serviceman was there on time and even went out of the way to provide extra service out of work our, price was lower than expected

By the book plumbing service, Master Techinican
Leon Mcirvin, wasn't trying to rip you but he gave us cost affective way to save money by digging our trench ourselves instead applying trench to the bill. He was kind and funny, he would crack jokes here and there make at me ease and his easy to work with he wasn't trying to intimidate you with plumbing terms and he would tell it how it was.

All I know is these guys are the awesome in the sauce, had a plumbing emergency and team BY THE BOOK showed up on time, diagnose the problem. And provided us with options. Thanks for your prompt service from the start to finish, 10 stars for customer service. I will be recommending this company.

Leon and team did a great job fixing a shower leak, getting the sink angle stops replaced and changing out toilet parts in my oldish home. He's very honest with pricing. Cleaned up after their work. Very nice and professional business. Will be reaching out again to help fix my gas fireplace. Would definitely recommend to others.

I recommend this company to friends and family as well as other businesses looking for speedy service. We needed emergency drain service at our industrial building and Leon arrived within a few hours on a very busy Monday. He was professional and took care of the clog quickly. By the Book Plumbing is definitely on my short list of reliable businesses in San Diego.

My toilet was clogged/ draining slowly and when I plunged it, water started to come out of the tub. I contacted several businesses but they were either not available for a few days, or they took my information and the tech never called back.
After a few hours of waiting, I decided to go back on yelp and find another plumber.

That's when I found By the Book Plumbing Service. Leon answered my call and came over in minutes. On a Saturday! However, by that time the toilet seemed to have fixed itself? Leon made sure everything was working by running the sink and flushing the toilet several times. He could have easily told me that he needed to do some repairs and I would have believed him. Instead he said everything looked good and said to call back if anything changes.

I appreciate having an honest and reliable plumber that I can go to now

WOW! These guys are incredible. Don't be fooled by the lack of reviews on their page, they are new to Yelp. I gave them a call Saturday morning to help us with a troublesome clog and they arrived within an hour. They were very friendly and courteous, had really nice new looking uniforms, and explained everything they were doing while they did it. I mostly spoke with Leon and it is apparent, he is a master in this trade. He knew EVERYTHING about plumbing and offered to walk around and teach me about our current setup while doing a courteous inspection. Generous prices, quality work, great appearance, and incredible professionalism, these guys will be my go-to moving forward.

Our water heater went out this morning and By the Book Plumbing was out to fix it within a few hours. They were fast, professional, friendly and reasonably priced. Highly recommend!!

I have used their services twice in the past few weeks. They have always been very responsive. I needed some drains to be cleared as well as an issue with my hot water heater. Communication with Leon was good. They were able to clear the drains and fix the water heater. Other improvements were discussed but no pressure was placed on doing anything immediately. They were very open to questions and explained the problems well. I've been happy with their service.

We have a gentleman coming out to help us with our bathroom sink leak today. He is super helpful and kind. He gave us a very reasonable price. He was on time and very nice to talk to. I would highly recommend him if you have any issues with AC or leaking or bathroom remodeling.

Leon was recommended by good friends.  He lived up to the high praise they gave him.  He got us on the schedule quickly, installed the new kitchen faucet in no time, and left everything clean and tidy.

Leon was excellent! Responsive, easy to work with and knowledgeable. Would work with him anytime. Multiple plumbers came and did not fix it, but Leon did.

Leon was able to come over on Sunday night and solved our problem quickly!
He fixed our water heater and now it is working without any problem

Leon Mcirvin was fast and professional. As soon as he showed up he went straight to work and gave me 4 quotes and how to save money. I highly recommend his services if you are in need.
