"Juan, the owner of the business was neat, professional and courteous. He is licensed and vaccinated. He explaned what he could do, then wrote out a quote, reviewed it again and then went to work on it. He brings all of his own tools including towels to clean up his work, his own pail for the garbage, he had a large floor mat he used to place the oven on while he worked on the gas supply line behind the oven. I highly recommend True Blue Plumbing and Rooter!"

"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"We had plumbing issues at our new home and were unsure how and what to fix. A friend of mine recommended them to me. Michael came out and accessed our issues. He quickly addressed our problems but noticed our pressure was really high causing all those leaks to occur. He restored our pressure to a safe range and now our new home is LEAK FREE! Iâ m glad my friend recommended this company to us. I highly recommend them, Michael was very professional and knowledgeable. Will definitely recommend them to friends and family!"

"Jose and his co-workers were great. He arrived promptly, figured out where the clogs were and cleared them with a combination of hydro jetting and root cutting. When the work was completed he tested for clogs and installed a riser and cleaned up so you couldn’t tell any work was done at all. Highly recommend So Cal Plumbing and Rooter!"

"I live in an old apartment building with old pipes. Sink was stopped up since I moved in 5 years ago and a regular snake would not unclog it. Francisco showed up with a more robust snake and cleared it right up, and quickly too! He explained what the problem was, which I totally appreciate! Thank you Francisco"

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.
