    William was the only plumber I contacted who directly jump in helping customer. All other vendors just ask me contact info etc but William actually cares about the customer and work and his little one question helped me solved the issue without an appointment. Sometimes it's a very simple common sense and really appreciate his candid response. Thanks!

    We ended up having to install a pump but Will had advised me before I signed the contract that it might be required.

    We had a line blockage on Thanksgiving Day that forced us to relocate our entire 16 person dinner…read moreto my sister-in-law's place in the next town over. We subsequently had our line hydro-jetted by another company who provided a quote to repair a partially collapsed section of the line. The quote was high enough to warrant two other quotes, one of which was Advanced Trenchless (AT). I decided to choose AT for several reasons: first, they provided the Goldilocks quote that was not too high but not questionably low like the third quote; second, they narrowed the scope to just the collapsed part, not the whole section of crawl space behind it as the first one quoted; and lastly, I got a call from Ryan, one of the owners, who explained the unknowns and also confirmed that a permit was required, which the last quote omitted. Also, he was willing to accommodate my schedule after the holidays. As others here have noted, AT's team are true professionals. They showed up first thing in the morning, were prepared, polite and zeroed in on the exact location that needed to be addressed. I hovered some to try to understand the mysteries of outdoor plumbing, learning that work done on a past remodel was not done properly. The fix was quicker than I was expecting. Everything went smoothly, including the Central San inspection, before they closed up the space around the new pipe and cleanout, leaving everything tidy, even putting back a section of shrub that needed to be moved. Can't ask for more than that. Anyone in Lamorinda looking for quality plumbing and septic services should consider Advanced Trenchless. You can trust them to take good care of you in a timely manner at a fair price.

    Horrible experience Glosage Engineering was contracted by…read morethe local sewer district to replace the main sewer line (not the lateral), trenchless. There is a utility easement along the property line, so no problem giving them access. They gave us a description of what they are going to do, and that seemed fine. However, reality looked much different. First they placed the line further into our property than planned. Then they excavated a huge hole, digging plants out and cutting irrigation lines. Next they decided to actually pull the new line across our entire property, damaging more plants and ripping out sprinkler heads and rocks embedded in the slope to prevent soil erosion. I pointed all these things out to Glosage's foreman and they promised to take care of it. Nope. They filled the hole, haphazardly put the tree back in the ground (not even streight) and just took off. I called them and the sewer district, nothing ever came out of it. The sewer district admitted that they had issues with that contractor and many complaints. I ended up spending a couple of hours and some spare parts from Home Depot to put things back in order. So my gentle advice: Be very careful with these guys!

They did what they said they would do and overcame any obstacle that arose without any complaint. The quote was 100% accurate, even though they incurred more cost than they originally thought. They completed the job on time and on budget which is rare in my experience as a home owner. It truly was a pleasure dealing with them and I wouldn't hesitate to recommend them to any of my friends and family. I had bids that were twice what Luis quoted, from 'supposedly' reputable local plumbing firms - for the same job.

When Carlos came to get an understanding of the job, he immediately stood out as having a deep understanding of what was needed to accomplish my goal. My job was small but a bit complex, pulling 2 conduits 80ft underground through a shared driveway, with a lot of slopes and tree roots involved. He thought about everything and came up with a plan and provided a clear price estimate on the spot. After getting 3 other quotes, TrenchFree had the most compelling one, both in price and plan to get my job done. They were flexible in scheduling and worked with me to fit their job into my overall backyard project timing-wise. Armando came out the day of work and again he was very professional, detailed, and made sure everything looked correct before the actual drilling began. He took the time that morning to double check 811 markings and even my private lines to ensure no utilities would be in the way. The job took a bit longer than anticipated due to the ground being filled with roots, but they kept going at it and finished the job in 2 days. I can tell it was a very physically demanding job and all the workers I encountered, Miguel, Pablo, etc were very courteous and made sure to clean up and leave everything in good condition before leaving. Overall, I am very impressed at the outstanding job they did and would definitely reach out to them again for any underground drilling work. Thanks again.
