Leon was awesome!

Great job highly recommend

Hey Leon, thank you for being such a great plumber and coming out to our office building and handling the smell that was going through the hallways! We had several tenants complaining about a smell of sewage in our office building and we’ve had two plumbers come out and could not figure it out. Leon With By The Book Plumbing came and he literally just poured some water in a floor drain and the smell stopped. It was a five minute repair for him where other people were trying to charge us like three grand to open up walls and see what they could find. He didn’t even charge us! So I’m writing this review. If you’re looking for an honest Plumbing Company By The Book is the one

Leon was absolutely outstanding. Professional, honest, and incredibly knowledgeable from start to finish. He showed up on time, explained everything clearly, and fixed the issue quickly without trying to upsell unnecessary work. You can tell he genuinely cares about doing quality work and taking care of his customers. The whole experience was stress-free, and the plumbing repair in my bathroom was done perfectly. It’s hard to find reliable plumbers these days, but Leon exceeded expectations. I would highly recommend him to anyone looking for trustworthy and high-quality plumbing service.

Leon is a great family guy that runs an honest business.

Geramiah and Cain replaced my shower valve today and they killed it! Great customer service, friendly guys and the shower works perfectly!

Had a mini emergency with our bathtub stopper Saturday morning. Jeremiah came to fix our issue, and there was no "overtime fee" that some plumbers have during the weekend.

Hes an honest man and would recommend him for any plumbing issues!

Service was quick and great. Jeremiah showed up on time and got right to work. The repair was simple and done expertly! Thanks Jeremiah!

Cleared kitchen sink blockage in minutes when other companies wanted to replace pipes. Honest diagnostics win!

Their sewer camera inspection found a collapsed pipe BEFORE it caused disaster. Preventative care pays off!

Emergency pipe leak at 10 PM. They answered, came out, and fixed it without gouging us. Integrity matters, and they have it.

Our old AC struggled all summer. By the Book recommended a perfect replacement. Installation was smooth, cleanup impeccable. Now our home is an oasis. Five stars isn’t enough!!!

Here, we had a rare rainy week when the sump pump broke. By the Book made sure our basement remained dry, inspected the drainage, and promptly restored it. We avoided expensive water damage thanks to their quick response.

The upstairs was not being cooled by our ductless air conditioner. They recharged the system, repaired duct leaks, and cleaned the coils. There are no more sweaty nights, which is a huge change! Outstanding service from beginning to end.

A unexplained leak in our pool's plumbing caused water to drain every day. These guys identified the problem, fixed it, and made the pump system more efficient. The water bill has returned to normal, yet our pool continues to be full. Outstanding work!

During a routine HVAC maintenance check, they spotted a cracked vent that could’ve led to carbon monoxide issues. They repaired it immediately and cleaned the entire system. Proactive care like this is priceless.

Installed a new water heater last week, and the difference is incredible. The technician walked me through the options, helped choose an energy-efficient model, and completed the job in one afternoon. No upselling—just straightforward, quality work.

Discovered a hidden water leak under our sink that was causing mold. They handled the leak detection and repair swiftly, then advised on preventing future issues. Their attention to detail and friendly approach made a stressful situation manageable.

Our AC stopped working during the heatwave, and these folks came through same day. They fixed the refrigerant leak, replaced the filter, and cleaned the vents. The system now runs quieter and cooler. Highly recommend their HVAC repair services to anyone in San Diego.

The shower in our guest bath had low pressure for months. By the Book not only repaired the pipes but also installed a new shower head and adjusted the valves. They explained everything clearly and left the area spotless. Five stars for professionalism!

Woke up to a flooded laundry room due to a burst pipe. They responded immediately, stopped the leak, and restored the damaged area. Their emergency plumbing services are worth every penny—calm, skilled, and efficient!

Leon is the absolute best. He is so nice & so knowledgeable. He has all the experience and yet he's still patient & ready to explain & help in any way he can. So rare to find someone like that! I would absolutely recommend him & will be using him in the future for any other issues I have.

These guys were very professional and fast. I would definitely recommend them to any family or friends.

Leon was in the plumbing aisle at Home Depot and looked like he knew what he was doing there. I clearly did not! After waiting for two Home Depot associates to be called and not to show up, I asked him for help with finding a part. He took the time to walk me through and explain the part that I needed and why. I just wanted to commend you on hiring such a thoughtful professional man in your company. He was very professional and very knowledgeable and very thorough. He also promoted your company if I couldn’t figure out what was going on in our situation, which I appreciated. Thank you for taking your time to help. Be blessed as you are a blessing.

Stan Smith was the serviceman that saw to our issue. Truly a nice person with the best of social skills. Friendly and gracious. Beyond the personal aspects of Stan however, his work was methodical and he took care to explain it along the way. Having an expert carry the nonexpert (customer) through the process was comforting and reassuring that all was done well and right. It seems hard these days to find a company who deserves loyalty, but I’m pretty comfortable keeping these guys at the top of my list.
