"I normally don't call for help. I am the type of person who would try to fix things myself before I seek for help. Almost a month ago when my old tankless water heater kept giving me error code and with no hot water. I tried two weeks of either fixing it by watching Youtube or have other plumbers come over to take a look at the issue. None of them were able to help me resolve my tankless water issue. After 2 weeks of no hot water, I decided to give HomeAdvisor and Aaron's Plumbing and Rooter a try. Aaron came over the next day and point out the issues with my old water heater and suggested me to replace a new water heater with dedicated gas line. After 2 weeks of no hot water and researching issues that might happen to tankless hot water, I was convince what Aaron suggested. Aaron was very thorough and professional about the entire installation process. After the installation, there was error from the new tankless water heater. Aaron came out immediate to help resolve the issue. After countless hours of debugging and process of elimination with the technical support person from the water heater manufacturer, the issue was finally resolved due to a defect ignition rod from the manufacturer. I want to thank Aaron for his time and effort to restore hot water to my house. Aaron will be my go to plumber if I ever need plumbing help. George"

"Glenn and Josh are great guys. We had an emergency with Sewer blockage and they were at our house within an hour on a Friday evening. They cleaned it and also pointed out that we had old cast iron pipes which had cracks. Subsequently, we engaged them to replace all our sewer lines. The work was done within 3 - 4 days and they kept us up to speed on every aspect. The work was excellent (and they showed pictures to prove it). We would hire them for any of our plumbing needs and highly recommend them!!"

"When a pipe burst in our garage, we were pretty stressed trying to figure out what to do. Ron came out right away, shut everything off, and replaced the section of pipe that broke. He worked quickly but also took the time to explain what had happened and how to avoid it in the future. Really grateful for how calm and professional he was in a stressful situation."

"We needed a building cleanout installed as a requirement for our remodeling project. Cornelio was very thorough in investigating what were the requirements for the inspection. He installed a dual cleanout following all the requirements which will help us in case of any backups in the future. He was very transparent about the cost, and finished the installation on the following day. Highly recommend him for any plumbing issues."

"Jess helped us out with the huge job of replacing the entire sewer main pipe from under our house to the sidewalk given that our old cast iron pipes were corroded and kept getting blocked by roots. This was a 3 day job involving a multiple person team. We went with Jess given that his estimate seemed fair and beat out other competitors. The work ended up being more labor intensive than anticipated, as digging to the city sewer line, which should have taken hours, ended up taking a day and a half due to unseen gnarled roots and cement in the soil. Despite this, Jess and his team worked diligently, showed up when they said they would, and finished on time. They were courteous, professional, and very hard working. I will not hesitate to contact Jess for our future plumbing needs. Photo shows old pipe vs new pipe."

"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."

"We recently had Major League Plumbing & Rooter complete a sewer main repair at one of our commercial properties, and we couldn?t be happier with the service. From the initial inspection to the completion of the repair, their team was professional, knowledgeable, and extremely responsive. They clearly explained the issue, provided honest recommendations, and kept us informed throughout the entire process. The crew arrived on time, worked efficiently, and completed the repair with minimal disruption to our business operations. Their attention to detail, cleanliness, and commitment to quality workmanship truly stood out. Commercial plumbing issues can be stressful, but Major League Plumbing made the entire process smooth and hassle-free. We highly recommend them to any business or property owner in need of reliable, professional plumbing services. Thank you for a job well done!"

FAQs for sewer main install, replace or repair projects in Los Altos, CA

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
