"**Highly recommend FDL Plumbing!** Francisco from FDL Plumbing was prompt, professional, and efficient. He arrived at 10am to diagnose my water heater issue and clearly explained my options. After discussing pricing, we agreed to proceed, and Francisco had a new unit installed by 11:45am, exceeding his initial timeframe. Francisco was a pleasure to work with â he completed the job expertly while maintaining a friendly demeanor. His work ethic and competitive pricing (especially for San Francisco) were refreshing. Thank you, Francisco, for the outstanding service!"

"Excellent service by Cornelio & Edson. They came for an urgent same day service for the bathtub handle that fell off. Upon further inspection they found the pipe to have been rusted & stuck. They went above and beyond to repair. Extremely satisfied with their service, they are reliable and I would highly recommend."

"Guy who came gave me good advice and advised that he felt my issue was not needed for repair. He didn't try to sale me any service as he saw no need. I appreciate a plumber who isn't trying to get work out of people whom don't need it."

"We thought we needed just our washer drain unclogged so we called the company that had fixed that before, you guys. Guys came out. Under the house they discovered rusted sewer lines. When we had our plumbing redone years ago, the company who did those did not remove the old lines. Those old lines were up against the sewer lines and were corroding our sewer lines. So we had to replace the sewer lines. A broken line just before the city line was discovered so we had to replace that too. Anyhow, we so appreciated the kind workers who smiled and waved at us. They worked around our water schedule as we have a physically disabled adult son we care for. They let us watch all the things they had to do. I took pictures and the guys were fine with that. My brand new front yard was not ruined by trenchless sewer system that went in. And my yard looks like we never had sewer lines done. It was amazing. Yes, we would recommend you to all."

"I had a sewer backup and late in the day called around and In & Out was there the next morning. Several of the other companies either didn't return calls or would not give me a time they would be there. In & Out cleared the drain and showed me the cause of the problem, roots and broken pipe. They gave me a quote for a new line on the spot and the next morning they started the work and did a fast very good job. I'd hire them again without a doubt."

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend."

"Short version:
They got the job done, but it took two visits and cost about 2-3 times more than it should have because they initially arrived with the wrong equipment and then recommended an unnecessary, expensive video scan. The extra cost was due to their error and they should have covered at least some of it (if not all) but they refused.
Details:
Our sewer line backed up between our house and the street, and so I called In and Out to clear it. They arrived with nothing but a hand snake because supposedly other equipment was in the shop. The plumber was able to (temporarily) clear the obstruction with the hand snake. Charge: $250, which also included cleaning the trap in one of our interior sinks. So far so good (although if I'd known they'd come with just a hand snake, I would have done it myself...)
Two weeks later, the line backs up again, because the hand snake only punched a small hole in the obstruction rather clear it completely. I called In and Out to come back with the correct equipment.
This time they arrived with the proper equipment, including the full sized snake and water jet to clear the roots. Given the previous failure to remove the blockage, they recommended sending the video camera down the pipes to diagnose the problem. Problem = roots from the trees near the sewer line (surprise!). They used the snake + water jet to remove the roots and clear the obstruction. Now everything works. Bill = another $775.
Why do they get a C grade?
Issue 1: they refused to refund any of the money from their first, failed intervention. If they'd just arrived with the right equipment, we would have removed the roots on day one, sparing us another sewer back up and another expensive visit. They brought the wrong equipment and didn't solve the problem -- there should be at least a partial refund. Even an apology would have been nice. But I didn't get either. instead, we come to Issue 2
Issue 2: when they came back, they recommended an unnecessary (and very expensive) video scan of our system which just turned up the obvious problem of roots from the nearby tree.
Total cost was over $1000, for a job where most plumbers would have just gone in with the big snake + jet on day one and knocked out the roots for $250-400. In and Out ultimately fixed the problem, but we had to endure 2 days of sewer back up and paid 2-3x what we should have.
On the plus side, they were always very prompt, professional, and friendly in person (aside from issues noted above)"

"Steve installed an earthquake gas shutoff valve. He carefully and thoughtfully considered the best way to make it fit in the limited space, and ultimately came up with a super-efficient solution that required a minimum of new piping. He explained and demonstrated how it worked, and how to turn it on and off. As he turned on the pilot light for the water heater after installation, he explained how to do it if I ever needed to do it myself. Quick to respond to my initial inquiry and further questions. Excellent service -- highly recommended!"
