Robert was my estimator and project manager. He was fair and understanding and helped me whenever he could. Amanda in the office was excellent. Overall, they did a great job. I was a licensed contractor for almost 40 years and understand the big picture. They knew what they were doing and I would highly recommend them for any of your sewer needs. James read more

First time home buyers here! Alpha Trenchless was great to work with from start to finish for our sewer lateral replacement. We had gotten quotes from other local companies, some much higher and others incredibly predatory (promised discounts if they didn't have to pull permits, etc.). Alpha was the only one who was straightforward, but also genuinely kind and honest. We were most comfortable working with them and I'm so happy we did. They called us and squeezed us in quickly which was great! The guys on the job were so awesome and respectful. We had a very angry/nosy neighbor situation who felt permits with the City of Petaluma simply weren't enough and we also needed to go through the permitting office of Mr. Neighbor -- I'm not joking. He was awful, but the guys carried on, completely undisturbed and also gave us assurance that we did everything right. They took incredible care with ensuring the sidewalk concrete was done correctly and cleanly -- matching with the rest of the sidewalk. Just really went the extra mile. Highly recommend this business. read more

We had Alpha Trenchless do a sewer lateral replacement and they performed at a high level. All their employees were courteous and very hardworking. The work was completed in a timely manner and as promised. They cleaned everything up afterwards so we barely noticed any disturbance in our garden or yard. Thanks Alpha! read more

A friend recommended Alpha Trenchless and I'm glad I went with them. Our sewer lateral was above average job--the line was long and our house sits on a hill--but they handled everything smoothly, including permits, inspections, and professional patching the road when the work was done. Communication was great, they showed up on time, which is an additional bonus if you know what I mean, and the quality of their work was excellent. I got quotes from 2 other companies and confirmed for myself that Alpha Trenchless was not overcharging me. I could easily highly recommend them! read more

See all

Alpha Trenchless did a great job on sewer pipe repair. From camera inspection before and after, to cleanup after job completion. They were on time and finished when they said they would. We highly recommend them. Give them a call and you will be happy you did. read more

Impressed with everything about this company. The communication was spot on and from the first contact, everyone has been super friendly and responsive. Javier came out today and instead of giving me a quote for pipe bursting which I told him I thought I needed, told me my system could hold up for years as long as we aren't abusing it with non-bio-degradable things down the drains. I assumed he owned the company based on his knowledge on not only the sewer but plumbing in general but if he's not, I'm even more impressed! He said a good hydro-jet would be worthwhile - don't know if they do hydro-jetting but calling about that now and if I do have a problem with my sewer, I know exactly who I'm calling! read more

We had to replace the sewer lateral after moving to a new home, and we talked to several companies before deciding to go with Alpha Trenchless. What made the difference for us was their clear understanding of our property's unique challenges (slope with minimal clearance underground.). We were told right away that this particular job could not be done in a trenchless way, so we fully understood the limitations and the process. The best part was when I asked Javier, who came to give the estimate, how our new garden landscape would be handled during the job. Javier told me that his crew would do it's best to make the yard look exactly how it was before the job. And that they did! This company has a very professional and friendly staff, from Amanda in the office who kept us appraised about the scheduling, timeline and permits, to the technicians who always kept the area safe and clean while undergoing a massive structural improvement. The patch of concrete in our front patio looks like it was there all along, as does the street patch of asphalt along our residential drive. While buying a new sewer lateral wouldn't be top on my list of how to spend money, Alpha Trenchless really made it as painless as possible. I highly recommend this company and thank them for a great experience. read more

I'm shocked by the unresponsiveness of this company. Based on the stellar reviews I read here, I had someone come out to quote us a price on a drainage project. The person who came over had some good ideas about what needed to be done and promised someone would be by to do some further measurement so they could propose a bid. A week went by. I reached out to the ownership on Yelp. Got a canned response. Another week went by. Said they'd send me the proposal when it was ready. Then.... ghosted? My last message to them was "if you are too busy to quote or do this project, I would appreciate the courtesy of a response." Crickets. Reminds me of a saying I learned in business: "How someone sells you indicates how they will decide you." Guess I got my answer. ** Update: I was further disturbed by the response to this review. It suggests I asked for free work. Not true, as evidenced by my multiple messages asking for an estimate for the repairs. I like to support our local businesses, but when business owners do not respond to prospective customers after promising to promptly follow up, this is the only recourse we homeowners have -- to warn others based on their experiences. ** read more

This review is definitely overdue. After three to four other quotes, calls and lots of time, I found Alpha. Professional, responsive, reasonable priced (compared to all the heavy hitters out there) and got the job done when they said they would. We were in a tight timeline with a renovation and needed a new sewer line, new clean out etc. Alpha had the guys come out do the work and the owner was onsite inspecting what his guys had done. Most companies dont do that. I would highly recommend. read more

Great communication, quality work and super efficient. This is my second experience with replacing a sewer lateral and I was blown away by Alpha Trenchless's top notch service. Good communication, timely estimate and service and attention to detail. Everyone was so kind, hardworking and responsive to my concerns. Would not hesitate to hire them again! read more

We got three quotes to replace our sewer lateral, and alpha was by far the most reliable, responsive, and helpful of the companies. Patricia was an absolute rockstar to deal with, and their crew was fast, effective, and clean. It's amazing to have your yard look exactly as it was before the work was completed. Alpha rules! read more

I had another provider come to inspect my sewer line and after they told me that it needed to be repaired to the tune of $25k, I called Alpha Trenchless for a second opinion. They came out at no cost to me and called me right away to say that the line was fine and no service would be needed. I so appreciate the honesty and the cost-savings that Alpha provided - if I ever do need service, they'll be my first call! read more

I highly recommend Alpha Trenchless. I got five estimates to have my sewer lateral replaced. I researched and asked lots of questions, which Alpha (Esperanza) promptly answered. Some companies insisted they would have to do four excavations, including in my driveway. But Alpha Trenchless did just two, one at the house and one at the street. Their estimate was written with clear language. They coordinated with all utility companies and scheduled all inspections. During the job, they attended to every detail and left my property exactly how it was before they'd arrived. Plus, everyone was extremely nice. One factor that I didn't fully appreciate was the unpredictable costs to patch the street. It turns out that the city public works department determines this cost, which can't be determined until the end of the job. In my case, it was pricy. That being said, the final costs from Alpha Trenchless were still the lowest of my five estimates. Of Note: Three different Novato inspectors told me that they do great work, so I'm confident that the final product is high quality. read more

We were in a dilemma with sewer lateral that broke on a shared driveway over 300'. We had several local companies come out and hand us huge quotes for complete lateral replacement. We found Alpha Trenchless out on San Pedro Rd doing a huge job. My husband stopped the car and went to ask them about our situation. Javi came out that same afternoon and we had a quote the next morning. They came out and worked for us quickly and methodically. We were so grateful as with a shared driveway where laterals were practically on top of each other not to mention all the utility cables to deal with. We had everything accomplished in two days to our relief. They restored the ground to better than it looked before they started. We hired them back to complete some other projects that we need to accomplish. So happy we pulled the car over to approach them to help us. Would recommend them highly with no doubts. read more

A joy to work with! Warning: this will be a bit long and detailed :), but I think it's a particularly insightful story, so here goes... We had an issue with our sewer ejector pump backing up and running, even when nothing was flushing. Javier from Alpha Trenchless (and his little helper one day :) diagnosed and fixed it quickly at *very* reasonable cost. He was also very honest and explained everything to us patiently in earnest detail. And we know this is definitely true because he was the *third* team to come out, so we inadvertently got detailed comparisons of Alpha Trenchless vs. two other 4.5+ star, rigorously-reviewed plumbing companies. Not to knock them, but just to be fair in telling the whole story: The first company we called has 4.5 stars and lots of reviews on Yelp. It charged us ~$400 across two trips just to video inspect the pump, basin, and pipe all the way out to the street. Then they misdiagnosed the issue and quoted us $15-20k to do a full project to "fix everything". When you're being asked to pay the price of a midsize Japanese sedan to fix a plumbing issue, you get additional opinions. The second company we called has 5 stars and lots of reviews on Yelp. A couple of nice gentlemen came out, took a look (literally a look), and quoted us $2k to come back the next day to take apart the pump and evaluate it. If that came back OK, *then* they said they'd come back again at (unknowable!) separate cost with video snake thing to inspect the pipe out to the street. On a whim, I called a third company also highly-rated: Zaragoza Plumbing. They were booked that day, but mentioned that since there might be a pipe or larger trenchless project (per first company's $20k mention), I should talk with Alpha Trenchless who they knew well and recommended. I called them, a nice contact on the phone was very responsive. Javier came out a couple hours later and was almost apologetic about charging just a couple hundred bucks to immediately inspect the pump and basin, and video inspect the pipe out to the street. He then patiently explained with video everything he was seeing, taking care not to obscure any detail behind hand-wavy expertise. Within that, he didn't trash the first company, but did explain using the in-pipe video where he disagreed with the assessment that we would need to do a huge project. I felt so much more confident in my understanding of what was happening in that short conversation than all of the chats leading up to it, that I actually immediately went and wrote down all the detail in an email to myself for future knowledge. He went over 2-3 potential routes, but recommended trying the least costly fix that would be a couple more hundred dollars. He was back a couple days later with parts in-hand as his schedule allowed to fix it. And he fixed it. My only regret is that it's taken me several weeks to remember to sit down and right this review. Best experience with a local service provider I've ever had. read more

Excellent service and workmanship from start to finish. They were prompt in assessing the issue, offering a solution, and getting the job done. Great communication from the office and on-site. Cleaned up everything at the end. These guys set the standard for professionalism. read more

This review is overdue since we had our main line replaced by Alpha over a year ago - but I want to give credit where credit is due! We had a broken, galvanized main line that was gushing water in front of our house....in the height of the pandemic. We called out various plumbers who gave us ridiculous quotes and could not stop the water gushing from our house until we agreed to a big project. We then called Alpha! They came out on a Saturday, immediately stopped the gushing water and promptly put in a trenchless main line with no need to rip up our driveway and landscaping. It was truly a lifesaver. I highly recommend there services! read more

Can't recommend Alpha Trenchless highly enough! Impeccable service, flawless attention to detail, absolutely great to work with. Their crew replaced the sewer lateral of our 110+ year old San Rafael house with awe-inspiring skill, expertise and efficiency. It was one of the most professional contracting operations I've ever witnessed. Like watching a great basketball team in action. Great communication from start to finish - and fair pricing. Look no further. Alpha Trenchless lives up to and surpasses these many rave reviews. read more

A bit long but content and context are important...Our sewer lateral started having issues in March of this year. We had it cleared by a great company, American Sewer and Drain (Efrain). Unfortunately we had to have Efrain come out 3 more times over the next 6 months. On the last visit (Sept.) he brought his camera and showed us that the lateral line was crushed to about 1/3 it's normal size. He tried to connect us with a plumber to fix it but it didn't work out. After a deep-dive into 'Qualified' lateral repair companies Alpha Trenchless was the best choice. The owner, Esperanza, returned my call the same day and that is when 'the magic' began to happen. She schedule Javier to come and provide a quote the next day. He spent several hours at our house analyzing the issue, including using his camera in a secondary cleanout and inspecting the lateral in the crawlspace in order to provide an accurate no-cost quote. It looked like a one day job but they were booked out 3 weeks. I told him my wife was having surgery next week and that it would be a nightmare dealing with the lateral every few days. When he left he promised to try and do it sooner if at all possible. We received a quote and a call from Esperanza that they could do the job in one day the following week. We accepted what was a fair price. I can't say enough about Esperanza, Javier and the crew that came to our home early in the morning and worked all day. They were all very friendly, professional and hard working. They dug out the area around the cleanout and a bit under a section of our front porch, carefully moving several plants and shrubs, and proceeded to do what they do best...replace a 10' section of lateral that had been crushed by a 6-8" tree root. I periodically checked progress and they always explained the process and the stage they were at. When they said they were finished I checked the area and jokingly asked: 'when are you going to start?' The area that had been a 3 foot square hole in front of our home was gone; it looked exactly the same as it did before they started the work. Amazing. Great company, great job and great people. If you are in need of this type of work, Alpha Trenchless is your company. There are a lot of plumbing companies with good ratings but if you read the reviews in full, you will see issues that should cause you to think twice. After reading all of Alpha's reviews I was convinced that they were the only choice. I was right, they are an exceptional company that did a great job and provided exceptional service. They clearly set the Standard! 5 STARS read more

I engaged Alpha Trenchless to repair and replace my sewer lateral. They were, for the most part accommodating at the outset and did replace the pipe, which seems to now be draining properly. However, I cannot give them a good review because we had some disagreements, and their behavior in response was rude, bullying, and offensive. My situation was perhaps a bit unique because the damage to my pipe was near the main in the street, and it was agreed that perhaps this was not my fault, and perhaps it was the fault of a utility company that had recently done work in the area. The City of Novato had agreed to consider compensation if they could see photographs of the damage. I thus spoke to the owner of Alpha Trenchless, and we agreed verbally that he (the owner) would take photographs of the damage for my use. This did not seem to be a problem, but upon doing the work, they chose to take an alternate route to the main, which meant they could not take the photos. Rather than calling me and informing me of this decision or asking what I might want to do, they just did their work and covered the hole, completing the project. The problem is that now I did not have photos. When I mentioned this, the owner was defensive and aggressive. He did not seem concerned at all about our previous agreement, nor did he seem to care that I would not have the opportunity to address compensation with the City of Novato. On the contrary, he was, as I said, defensive and threatening, if not abusive. read more

One of the best experiences I've had with contractors in Mill Valley. I contracted Alpha Trenchless to replace our sewer lateral in MV. We had reached out to three companies and from three quotes, theirs was right in the middle. We chose them because they were punctual, organized and their staff had great attitudes. Ours was a pretty big project and I was concerned it might take a few days to get this done. Luckily Alpha came prepared, they brought five crew members and all of the necessary equipment to finish the project in ONE DAY. I couldn't believe it! Javi and Juan were complete professionals the entire time. They kept me informed of what they were working on and why they were doing what they were doing. If we have any other plumbing needs we're calling Alpha Trenchless first. read more

This company, its customer service and competitive pricing were all top notch. We needed a large section of sewer lateral replaced within a short timeline. After receiving several bids, Alpha was the most competitive and the easiest to work with. Through permitting, the replacement and finalization of the project both Javi and Esperanza kept in touch with us through daily updates. The work was done with absolute care and they even went out of their way to keep the landscaping on the property minimally damaged. They are a great business and we will definitely use them moving forward. Thanks again Alpha! read more

Alpha Trenchless - Replacing sewer lateral all the way to main line with care. - Plumbing Near Me - Petaluma, California

They repaired my Mill Valley "sewer lateral" for $2,500, whereas I was expecting to pay about $10K! They arrived promptly, worked efficiently, and cleaned up thoroughly. As a bonus, their technician was happy to indulge my interest in their technology by explaining how everything worked. read more

I can't say enough about how great it is to work with this company ! Communications and service was amazing....they got a sewer lateral replacement project done like a well coordinated team with scheduling, getting the permits and inspections done by properly licensed and experienced professionals. They know what they are doing, and get it done right and on time. I also had Patricia send me documents I needed without even asking. They are wonderful to work with. A very satisfied customer for a Marin rental property. read more

We recently contracted with Alpha Trenchless to replace our sewer lateral and were so pleased with the excellent service they provided. From start to finish everything was done so professionally. The communication was top notch. My many calls and e-mails were answered promptly. Everyone we dealt with was pleasant and knowledgeable. The crew was very skilled, got the job done quickly, and took care to protect our landscape. The clean-up was meticulous. Other than the patch in the street, there was no evidence that a big job had just taken place in our front yard! Definitely a thumbs-up for a great local and family owned business! read more

A long overdue review. I can't say how impressed I am with Xavier and his entire team. Getting a kick out of some reviews who complain about delays and non response ... hey folks this is plumbing and escavation - shite happens - literally! My sewer lateral was no exception. A beast of job - 300 ft. run down a steep driveway with 4 new cleanouts needed. Line was collapsed and in such bad shape Xavier couldn't even get a camera down to verify for public works permit. Xavier spent an entire morning just trying to clean out and get a clear run - most would have run from the job and Xavier stuck it out knee deep muck. Staff worked dilligently with public works department to jump hurdles and get permissioning (street had just recently been repaved) and final certificate of completion. Efficient, reliable, communicative AND extremely fair. Best contracting experience I have had in 40 years of building projects. FYI - I would skip the $50 rebates that arrive in the mail from Best of Marin and 5 star rated large plumbing firms. You will pay dearly. The quotes I received from these businesses were ridiculously overpriced - actually the price difference was embarrassing! read more

Alpha Trenchless replaced our sewer lateral in Mill Valley and we had a really positive experience - would definitely recommend their services to anyone else looking to have this done at their property. Their front office was always responsive, the work provided was done in less time than they estimated, just less than two full days of work, and the cost was reasonable. Definitely reach out to them if you need to have a sewer lateral replaced. read more

We needed help with a gas line, and Fernando and the team at Alpha Trenchless was great at analyzing the problem and delivering a solution at the lowest price among the three licensed contractors we interviewed. Patty in the front office was also very responsive and helpful. A*! read more

Alpha replaced old lateral sewer pipe from the house to sidewalk connection and added 90 feet of new sewer and water pipe for an ADU in Marin. Javier was prompt with a competitive bid. Patty scheduled the work and guided us threw the permit process. The crew arrived on time, updated odd and old plumbing, installed more than 100 feet of pipe, and returned carport, flagstone stairway, and landscaping back to pre-construction grandeur. Great team; Great job! read more

The team did a fantastic job of replacing our sewer line, on time, on budget and with a smile. Highly recommended. read more

We enjoyed working with the whole team at Alpha Trenchless. They were very responsive by phone and email, very reasonably priced and clear on expectations. We appreciated the helpful photos and video from under our house showing before and after the work. The crew were quick and kind and adapted to what they found underground. We will work with Alpha Trenchless again! read more

I just wanted to thank Sara and Javier for their professionalism through out this process. I only needed a quote and really someone to bounce my concerns off, Javier was awesome! He gave me some alternative ideas but let me know if we really want to go a different route to contact them. Thank you again Sara and Javier! read more

Guy did great job scoping my sewer lateral and also marked the area for me. Very nice and professional worker

we searched for this company for awhile, and they were perfect. did great work (connecting us to a city sewer) , reasonable price,

Bought a new house and had to replace the sewer lateral. Alpha gave a great quote (saved me thousands) and Javier handed the job professionally, including great communication along the way. He knew how to move things along with inspectors and had the relationships to make everything as painless as possible. Highly recommend. read more

I needed to replace sewer lateral line for my house in Mill Valley. I contacted Alpha Trenchless. Alpha Trenchless had done an excellent job from the beginning to the end of the project. Starting with the office manager, Esperanza, she was very responsive to my request (almost instantly). More importantly, her customer service skill was very professional. Then to the project manager (Javi) and their technicians, they were all very nice and professional as well. They finished the project in 2 days. Part of the project required digging a few holes in my yard as well as on the city street. Upon the completion of the project, I can't even tell that there were holes digging during the project. They patched up and put everything back exactly the way it was. Of course, the most important part of the project is coordinating with the city inspector as well as the inspection result. Everything passed the inspection in the first time with no comment. I'm very impressed with Alpha Trenchless work. Thank you very much again Alpha Trenchless for your excellent work. We need professional contractor like you to help us. Best wishes, Duy read more

Alpha Trenchless did an amazing job of replacing our sewer line and additional issues discovered along the way. Professional, courteous, extremely tidy. Highly recommend! read more

So impressed by this company. Javier responded very quickly to my call and assessed my plumbing problem in minutes. I was all set to have my water line replaced because none of the other plumbers I called could tell me why I wasn't getting water. I felt desperate and didn't want my whole yard dug up and thought a trenchless company was my best bet. I had previously worked with another plumber to install a pressure valve on my lines and it seems that he put everything on backwards! Javier spent the time to investigate and found that all that was needed was an inexpensive repair to correct all the mistakes made by the previous plumber. It speaks to his honesty and integrity that he did not take advantage of the situation and tell me I needed a new line. Esperanza in the office is very efficient and friendly and I felt I was in good hands. They even put me in touch with someone to help with my irrigation problem. Highly recommended read more
