"Juan came to the house and installed a new gas valve controller for my RHEEM water heater. He honored his over the phone price quote, and did a great job. He even checked my water pressure. No run-around here, just the honest truth from True-Blue Plumbing."

"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 located Alliance on HomeAdvisor and the contact called me within 5 minutes. He came to my home to quote the job within 30 minutes. I got several quotes and they had the best price. We scheduled a date and they completed the project. What I like the most is that they were professional, came on time, and walked me through the scope of work. They reviewed and tested the work with me after completion. I would definitely recommend and rehire Alliance again."

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.
